     This invention was not made pursuant to any federally-sponsored research and/or development. 
     THE FIELD OF INVENTION 
     Dangerous bacteria, viruses, and other pathogens are present in the air and on various physical surfaces, which are easily spread through air and by contact with contaminated surfaces. Certain pathogens, bacteria, and viruses are airborne, easily inhaled, and can travel quickly from person to person as well as settle on room surfaces. These airborne or surface pathogens can cause infections, illness and even death to individuals who come in contact with these pathogens. 
     Methods of control are difficult and labor intensive, involving washing or wiping surfaces with caustic germicidal substances, leaving a film and/or smell of these substances on surfaces. An even greater problem was disinfecting the air to destroy airborne bacteria and other pathogens that could resettle on surfaces. Fast spreading viruses and other airborne pathogens are capable of settling onto room objects and re-contaminating surfaces immediately after the surfaces are physically cleaned and disinfected making it extremely difficult to maintain a safe, healthy, and germ/virus/pathogen-free environment. 
     The present invention relates to a self-contained air decontamination system, intended to install directly into or onto a ceiling in a room, in a non-movable or repositioning relationship, designed to destroy pathogens in the air drawn into the system and return decontaminated air back into the room directly from the unit. Further, present disclosure relates to a device that includes additional components designed to mount to the system such as ceiling tile in frame, room luminaire, and room surface and air decontamination luminaire in a hingable, removable, replaceable, and interchangeable. 
     BACKGROUND OF THE INVENTION 
     The benefits of devices that use ultraviolet spectrum light for killing bacteria and other pathogens are known in the art. Non-visible, Ultraviolet C or Germicidal light source technology is known to destroy the DNA or ability of viruses, bacteria, and other pathogens to reproduce. Visible light utilized on common light fixtures used as a light source is usually in the 400-700 nm range. UV light used to destroy viruses, bacteria, and other types of pathogens are typically below 400 nm (although any light below 400 nm is considered UV light). Some of the methods of using UV light for killing viruses, bacteria, and other pathogens are disclosed in U.S. Pat. No. 8,350,228 (Welker), the disclosure of which is incorporated herein by reference. However, Welker discloses an extremely heavy unit that requires disengagement from the mounting surface to pivot 90 degrees, below ceiling surface, for service or maintenance in a manner which is unsafe and may cause the unit to break free from its attachment means. The Welker unit breaking fee may injure the service technician or maintenance person, disconnect from the Install Apparatus (custom brackets required in Welker) and power supply connection, or cause damage to the installation facility. The complete germicidal unit of Welker is designed to disengage from ceiling to swing downward to allow access to the top of the unit to change the germicidal source. The combination of the Welker&#39;s unit weight along with the weight of the exiting troffer housing create a situation that may exceed the maximum weight for ceiling grid specifications designed to support a much lighter, standard troffer unit alone. 
     The current global crisis creates a new environment of exposure that requires greater need for decontamination systems. Existing facilities may not be suited to add additional germicidal devices to their installed ceiling systems due to lack of available space, congestion, or other items occupying the space required to install additional systems. There is a need to improve the quality of air including the decontamination of airborne microorganisms and pathogens in the air we breathe. 
     Air filters and other air processing systems involve ductwork or existing HVAC Systems that draw air into the facility HVAC System for processing. These systems are limited to larger ceiling duct systems where effective, where the HVAC air return duct is located and may not be capable of decontaminating office or hospital area distant from the return ducts. Poor efficiency will also result from offices or hospital rooms where doors are closed, making importing the room air into the return duct difficult or impossible. Facilities that include wall-installed HVAC ductwork are inefficient due to the return duct location at the perimeter of the room. 
     An essential element of quality air decontamination in a room requires a centrally located system capable of importing room air in an equal manner that assures a balanced and efficient process. This involves the use of facility ceiling or ceiling structures to position air decontamination systems in locations that can perform effectively. Positioning an air decontamination system in the optimal location may not always be possible in many facilities due to the lack of available space in the ceiling or in the ceiling recessed grid system. HVAC ductwork, lighting fixtures, electrical wiring, plumbing, computer wiring, joists and beams, and other objects limit the available area to install a new air decontamination system. 
     Most offices and hospital facilities have recessed or drop ceiling, also referred to as T-Bar, Inverted T-Bar, or grid ceiling, for aesthetic reasons in order to accommodate the various elements typically associated with a ceiling structure (wires, ducts, pipes, beams, etc.). Recessed drop ceilings also reduce the size of a room cavity by lowering the ceiling which reduces the cost associated with heating or cooling a facility. 
     Since HVAC system return ducts are not positioned in ideal locations and available space is limited in most recessed drop ceilings, the ideal location for an efficient room air decontamination system would be in the available space in the ceiling or in the space occupied by existing room luminaires. 
     Installing an air decontamination system into a centrally-located open space in a recessed drop ceiling would provide the most efficient system for air decontamination. Many offices and hospitals with recessed drop ceilings have recessed luminaires equally spaced in the ceiling grid. This often allows for several ceiling tiles be positioned between the installed luminaires. Depending on the ceiling grid pattern and location of the installed luminaires, an available space on the recessed ceiling grid that is occupied only by a ceiling tile would be an ideal location to install an air decontamination system. 
     What is needed is a ceiling-mounted decontamination unit, permanently mounted into the ceiling, which efficiently decontaminates the air passing (circulating) through the decontamination system to destroy the bacteria, viruses and other pathogens in the air and allows easy access to all components for maintenance and repair from the room side of the unit without disengaging the system from the ceiling grid. The unit should also be capable of replacing a recessed drop ceiling tile or recessed grid luminaire with an air decontamination system that is safe, effective, and user friendly offering fast and efficient maintenance for facilities where closing a room for maintenance is a challenge and costly. 
     The present invention solves this problem by providing a ceiling-mounted decontamination unit with luminaire, which the Applicant also refers to as a Recessed Ceiling or Surface Mounted Decontamination System, that draws in air from room or area, subjects the air in the unit to a decontamination source destroying harmful viruses, bacteria, and other pathogens, and re-circulates or returns the decontaminated air directly back to the same room or area. The present invention relates more particularly to a system and device that includes one or more UV-C emitters inside the housing, and one or more fans inside the housing that re-circulate the air in a room and subject the air to the germicidal decontamination source inside the housing, thereby decontaminating the air passing through the ceiling-mounted decontamination unit internal space and destroying viruses, bacteria, and other pathogens. 
     This ceiling-mounted decontamination unit includes a hingable frame, preferably with a latch, for grid ceiling tile to allow facilities to match existing ceiling type. The hingable frame allows a common recessed ceiling tile to be inserted into the hingable frame for easy attachment to the Recessed Ceiling and Surface Mounted Germicidal Decontamination System&#39;s hinge and latch provision. 
     However, the system can also incorporate a recessed grid ceiling luminaire, or room luminaire, to provide an air decontamination system along with a recessed luminaire capable of illuminating a room and being installed into the ceiling-mounted decontamination unit&#39;s hinge and latch provision. 
     In addition, in areas of higher concern with greater pathogen contamination, the system may incorporate a hinged Room Surface and Air Decontamination Luminaire into the ceiling-mounted decontamination unit&#39;s hinge and latch provision to decontaminate surfaces and air in a room. The hinged Room Surface and Air Decontamination System includes a decontamination source mounted on the surface of the Room Surface and Air Decontamination System exterior surface to make direct contact with the surfaces and air in a room. Similar to the Hinged Ceiling Tile in frame and the Hinged Room Luminaire, the Hinged Room Surface and Air Decontamination Luminaire is designed to hinge or open downwardly, toward the floor, to allow access to the maintenance panel on the air decontamination chamber for maintenance and repairs. 
     The components associated with the air decontamination system should accessible from below the installed unit on the ceiling grid. Access to the decontamination source, power supply connection, filer, drivers, ballasts, means for moving air, and all other components are available from below the installed unit, on the room side of the installed unit, and without moving or disengaging the air decontamination system from the installed position on the ceiling grid. 
     Installing an air decontamination system may require the removal of an existing luminaire from the recessed drop ceiling or other ceiling type. The device incorporates provisions to install or attach a room luminaire directly onto the housing of the air decontamination system that does not alter the performance of the air decontamination process. The system includes a hinge and latch provision designed to allow the attachment of a room luminaire that will illuminate the room as effectively as the removed luminaire. The hinge and latch feature combined with a custom-size luminaire is designed to install onto the front surface of the air decontamination system, preferably between the air decontamination air processing features. 
     In areas of greater pathogen contamination, the air decontamination system includes provisions to install or attach a room surface and air decontamination luminaire directly onto the air decontamination system that does not alter the performance of the air decontamination process. The system includes a hinge and latch provision designed to allow the attachment of a room surface and air decontamination luminaire that will effectively destroy pathogens on the surfaces and air in room where installed. Safety features are incorporated into the room surface and air decontamination luminaire decontamination sources. The hinge and latch features combined with a custom-size room surface and air decontamination luminaire is designed to install onto the air decontamination system, preferably between the air decontamination air processing features. 
     Light Fixture 
     The light fixture or room luminaire design is completely self-contained with all lighting required components attached or secured to the room luminaire. The room luminaire is dependent on the ceiling-mounted decontamination unit as a means of installation with provisions for attachment, hinging or pivoting, latch or securing device, and power supply means. When installed, the attached light fixture or room luminaire has no direct association with the Recessed Ceiling or Surface Decontamination System decontamination process but does provide a quality substitute or replacement light source when an existing light fixture is removed from the grid ceiling or other ceiling. 
     SUMMARY OF THE INVENTION 
     It is an object of the present invention to provide a ceiling-mounted decontamination unit that includes a housing designed to install, mount, or rest directly on an inverted T-Bar or drop ceiling grid, independent of any other device, incorporating one or more decontamination sources located within the decontamination system&#39;s internal space to destroy pathogens, one or more fans inside the system housing that recirculate the air in a room and subject the air to the decontamination source inside the decontamination system housing, destroying bacteria and pathogens in the air passing though the unit&#39;s internal space. Room air is drawn into the ceiling-mounted decontamination unit&#39;s internal decontamination intake aperture where the contaminated air travels through the systems decontamination chamber, or duct, where the air comes in direct contact with the systems decontamination source that destroys all pathogens in the air. The air decontamination source preferably uses wavelengths ranging from 100 nm to 400 nm. The decontaminated air then passes through the system&#39;s exhaust aperture where the air is returned directly, without additional ductwork, from the unit back to the same room. 
     Unit Directly Connected and Secured to Grid Ceiling 
     The ceiling-mounted decontamination unit includes integral provisions, such as pry-out clips, referred to as “Earthquake Clips”, designed to secure the ceiling-mounted decontamination unit housing directly to the recessed ceiling grid or T-bar system. These built-in clips are designed to prevent the unit from disengaging from the ceiling grid in the event of an earthquake or other occurrence that may cause a non-supported unit to fall from the ceiling grid toward the floor below. In addition to the integral Earthquake Clips, the unit housing has provisions secure the ceiling-mounted decontamination unit housing to the facility structure by way of support cables or ties, often required by building codes, directly attached to the facility structure. The ceiling-mounted decontamination unit is designed to preferably be permanently attached to the ceiling Grid or T-bar and not move in any way once properly installed. 
     Unit Connected to Grid Ceiling—not Moveable 
     The Recessed Ceiling or Surface Decontamination System housing size, length and width, is greater than the opening size or aperture in a drop ceiling. Once installed, the Recessed Ceiling or Surface Decontamination System housing is designed to remain in complete and direct contact with the ceiling grid at all times. The unit housing is not designed or physically capable of pivoting, hinging, or disengaging in any way from the ceiling grid, downwardly toward room floor for any reason. 
     Maintenance From Room Side of Installed Unit—Not Hinging or Pivoting 
     Once installed, all maintenance and access to components within the Recessed Ceiling or Surface Mounted Luminaire are performed from the room side of the installed unit, below the installed unit, with the unit housing remaining in direct contact with the ceiling grid system. All maintenance to the system is performed as installed the unit housing remains in mounted position, on recessed grid ceiling, with access to all components without hinging, pivoting or in any way disengaging the ceiling-mounted decontamination unit housing from the mounted position on the ceiling grid. 
     Modular—Tool-Free Maintenance 
     Costs associated with maintenance and repairs to certain facilities can be costly. Hospitals, offices, and other areas cannot afford to close rooms such as operating rooms, emergency rooms, of high traffic areas for extended periods to make costly repairs on devices in room ceilings. The ceiling-mounted decontamination unit components are modularly designed for quick and tool-free maintenance by way of cord and plug attachment within the unit. Attachable hinge and latch features makes maintenance, service, and replacing components quick, easy, and tool-free. This user-friendly and tool-free design significantly reduces time required to shut down or close a specific room or area during maintenance and repairs. 
     Center Section—Drop Ceiling Tile (Hinged/Pivot) 
     The Ceiling or Surface Mounted Decontamination System includes a provision for recessed drop ceiling tile to install into a hingable, frame-like device that allows the drop ceiling tile to attach directly to Ceiling or Surface Mounted Decontamination System to maintain uniformity of the room ceiling appearance. The hingable ceiling tile and frame has the ability to open, by way of device&#39;s hinge and latch provisions, in a way that allows the drop ceiling tile to hinge, pivot, or otherwise open downward toward the room floor to access the Ceiling or Surface Mounted Decontamination System&#39;s maintenance panel, located or positioned behind the installed ceiling tile, for maintenance to the air decontamination source. The ceiling tile with hingable frame is equipped with a hinge and latch that are compatible with the hinge and latch provision located on the Recessed Ceiling or Surface Mounted System housing. This system includes any and all designs capable of installing into the hinging and latching system as well as other means of attachment including pivot, lift-and-slide, or other known designs as well other securing means such as screws, bolts, clips, spring clips, fasteners, latches, or other known devices known in the art. 
     Self Contained Air Decontamination System 
     The ceiling-mounted decontamination unit is a completely self-contained air decontamination unit, preferably with an anti-microbial finish, that requires no additional devices other than a power supply (currently AC). This system uses internal fans or other mechanisms known in the art to draw room air into one end of the air decontamination system where the air is in direct contact with the decontamination source then the decontaminated, pathogen-free, air is expelled or exhausted from the unit, directly without the need for additional ducts or ductwork. As the air passes through the unit&#39;s internal space, the air flows by one or more decontamination sources, preferably Ultraviolet-C, which destroys micro-organisms and pathogens that come into contact with the decontamination source, properly and effectively decontaminating the air before the air exits the unit. 
     Internal Air Decontamination Sources 
     The ceiling-mounted decontamination unit&#39;s internal decontamination source and optional external room surface of the present invention is Germicidal Ultraviolet-C (UV-C), preferably ranging from 100 nm to 400 nm wavelength. Ultraviolet light ranging from 100 nm to 400 nm is considered invisible light. Ultraviolet light sources considered less harmful to humans ranging above 400 nm, such as Ultraviolet-B (UV-B), Blacklight, or other visible light spectrum capable of destroying viruses, bacteria, and pathogens are options for both internal air and external surface decontamination systems. 
     Center Section—Room Light Fixture, Luminaire (Hinged/Pivot) 
     The Recessed Ceiling or Surface Mounted System&#39;s Decontamination System includes a provision for an optional room luminaire. The room luminaire is designed to attach directly to ceiling-mounted decontamination unit, by way of housings hinge and latch provisions, to provide general room lighting. The centrally positioned room luminaire has the ability to open downwardly toward room floor, by way of hinge and latch provisions located on the system housing, that allows access to the system&#39;s maintenance panel, located or positioned behind the installed room luminaire, for maintenance to the air decontamination chamber and decontamination source. The custom-size room luminaire is equipped with a hinge and latch that are compatible with the hinge and latch provision located on the Recessed Ceiling or Surface Mounted System housing. This system includes any and all luminaire designs capable of installing into the hinging and latching system as well as other means of attachment including pivot, lift-and-slide, or other known designs as well other securing means such as screws, bolts, clips, spring clips, fasteners, latches, or other known devices known in the art. 
     Center Section—Room Surface and Air Decontamination Luminaire (Hinged/Pivot) 
     Yet another option for the Ceiling or Surface Decontamination System includes a provision for a recessed-type Room Surface and Air Decontamination Luminaire to attach directly to Ceiling or Surface Decontamination System housing. This provides a room surface decontamination source or germicidal luminaire designed to destroy viruses, bacteria, and pathogens on room surfaces as well as in the air in the room where the unit is installed. The preferred Room Surface and Air Decontamination Luminaire source for decontamination uses wavelengths preferably ranging from 100 nm to 400 nm, ozone, or other known decontamination sources. The Room Surface and Air Decontamination Luminaire has the ability to open, by way of hinge and latch, in a way that allows access to the Ceiling or Surface Mounted Decontamination System&#39;s access panel, located or positioned behind the installed room luminaire, for maintenance to the air decontamination source. All known safety requirement provisions and warnings should be included with this option. 
     Ozone as Decontamination Source 
     Another option for the ceiling-mounted decontamination unit decontamination source is Ozone. Ultraviolet energy can be produced at 185 nm which is proven to effectively produce ozone, a natural sanitizer and deodorizer. Ozone is capable of destroying pathogens in the air and on room surfaces and has the ability to travel deeper into area where the standard or conventional ultraviolet light sources, 200 nm to 400 nm wavelength, may not directly reach. Since UV light sources are required to make contact with surfaces for proper pathogen decontamination, Ozone has the ability to reach areas that UV light sources are not reaching. Additionally, Ozone has ability to decontaminate air and surfaces such as under beds, under desks, behind objects, or any other place in a room where air/gas can travel. When ozone is used as decontamination source for room surface and air decontamination luminaire, a UV light shield device is available to block the UV rays but allow the ozone produced to effectively decontaminate the surfaces and air within a room. 
     Novel Design and Mounting 
     This ceiling-mounted decontamination unit includes provisions to insert or attach a ceiling tile or drop a ceiling tile into a frame that hinges or pivots open from the unit housing and to allow access to the Air Decontamination Chamber maintenance access panel, located in unit housing internal space, to replace the decontamination source or perform maintenance. 
     The device housing contains provisions that allow the housing to be directly installed onto or into a ceiling surface, recessed drop ceiling or plaster ceiling or non-recessed ceiling, without breaching the air decontamination system in any way. 
     Furthermore, the ceiling-mounted decontamination unit incorporates a provision to insert a drop ceiling tile into a frame that hinges or pivots open and to allow access to the Air Decontamination Chamber maintenance access panel within the housing for maintenance to the decontamination chamber and decontamination source. This provision allow for the hingable ceiling tile in frame, hingable room luminaire, or hingable recessed surface and air decontamination luminaire to be interchangeable at any time without the need for any modifications to the system. 
     The room luminaire provision feature includes a hinge and latch provision, once the room luminaire is installed onto the hinge system, allows the room luminaire to hinge or pivot downwardly, toward the room floor, from the mounted position in the drop ceiling to allow access to the ceiling-mounted decontamination unit maintenance panel located within the housing&#39;s internal space. 
     The features of the Recessed Ceiling or Surface Decontamination allow for interchangeability as well as tool-free removal and replacing the hingable ceiling tile, room luminaire, and room air and surface decontamination luminaire. 
     Unique Luminaire Power Supply Connection In System 
     The optional feature such as the Room Luminaire and Room Surface and Air Decontamination Luminaire are designed to connect directly into the ceiling-mounted decontamination unit internal power supply connection. These dedicated connectors are uniquely specific to each hingable, attachable and removable device provision and designed to provide power to each device. The power supply connection from the ceiling-mounted decontamination units consists of a power supply provision for room luminaire and room surface decontamination luminaire consist of a modular connection system, preferably female-type but other system is acceptable. Although the dedicated connectors are similar in function to an electrical wall outlet and designed to only accept similar male connector supplied on the optional Room Luminaire or Room Surface and Air Decontamination Luminaire. In the preferred embodiment of this system, the power supply connecting system is incorporated into all ceiling-mounted decontamination unit and available if needed or not. Units incorporating Drop Ceiling Tile in hingable frame will not require power supply provision but in the preferred embodiment the provision will be included in case a customer wishes to replace a drop ceiling tile with a room luminaire or a room surface decontamination luminaire at a later date. 
     Optional Center Luminaire Hinge and Latch System 
     The attached Room Luminaire, Recessed Ceiling Tile in frame, or Room Surface and Air Decontamination Luminaire include a hinge and latch provision which function in either direction that allows to unit to disconnect from the ceiling-mounted decontamination unit housing for quick and easy maintenance or replacement if needed. 
     Optional Center Luminaire Removable/Detachable Feature 
     The ceiling-mounted decontamination unit combines an internal air chamber and a decontamination source with a removable and detachable room luminaire feature that pivots or hinges from the provisions attached to the Recessed Ceiling or Surface Mounted Germicidal Air Decontamination System. The Room Luminaire and Room Surface and Air Decontamination Luminaire systems contain attachment cords with modular connections making the units easy to unplug and disconnect from power supply to allow for easy tool-free luminaire replacement. 
     Tool-Free Center Luminaire and Room Surface Luminaire Replacement 
     The ceiling-mounted decontamination unit&#39;s hingable Room Luminaire and Room Surface and Air Decontamination Luminaires are modularly designed with all necessary components attached to the Luminaire housing. To remove or replace, simply disconnect the power supply connector by releasing connector locking provision and unhook/release the hinge/pivot provision to remove the luminaire from the ceiling-mounted decontamination unit housing. To install a new or replacement luminaire, reverse the previous steps. 
     Installs in Same Space as Traditional Luminaire 
     One preferred embodiment for the ceiling-mounted decontamination unit includes provisions, between the air intake and air exhaust apertures, for a room luminaire. Due to limited space in facilities, the addition of an air decontamination device may not be possible. Most rooms are designed with lighting fixtures centrally located in the ceilings with power supply to the unit. Incorporating a room luminaire into a Recessed Ceiling or Surface-type Germicidal Air Decontamination system allows for a combination unit to function in the same physical space as the existing recessed room luminaire providing the additional feature of air decontamination in optimal locations. 
     Decontaminated Air Returned Directly to Room—No Ductwork Needed 
     This device re-circulates the decontaminated air from the unit&#39;s decontamination chamber directly back into the same room without the need for additional ductwork or other devices. By directly re-circulating pathogen-free air from the internal decontamination chamber and directly back into the same room, this device is suitable for all room types with all ceiling types. Since this device does not require additional ductwork to re-circulate the decontaminated air back into the room, this device is also suitable for sheetrock/plaster ceilings, concrete ceilings, and other non-recessed type ceilings. When installed in recessed ceilings, this device does not interfere with various obstacles above a ceiling such as HVAC ductwork, telecom, electrical wiring and conduit, water lines, water sprinkler systems, as well as other infrastructure items and structures. 
     Optional Air Filters 
     The ceiling-mounted decontamination unit may contain air filter systems located at the air intake aperture or air exhaust aperture, positioned prior to or after the decontamination chamber where the air is decontaminated, which may be accessible for maintenance by way of vent cover, grill, or access panel that is removable, hinged, or using other methods that do not require the unit to be moved, removed, pivoted, hinged, altered, or removed or relocated in any way from its installed/mounted operating position. The air filter is designed to be located at or on the vertical intake or exhaust ducts and not in the actual decontamination chamber in a way that the filter does not interfere with the decontamination chamber where the air flow makes contact with the decontamination source. This also protects the air filter from the UV rays when UV is the decontamination source. 
     Air Decontamination Source Access Panel 
     The Recessed Ceiling or Surface Decontamination System has an air decontamination source maintenance cover to access the air decontamination chamber or duct for replacement or maintenance to the system air decontamination source. The Room Luminaire, Drop Ceiling Tile in hinged frame, and Room Surface and Air Decontamination Luminaire are all designed to pivot or hinge open 90 degrees, in a downward direction toward the floor, for access to the systems maintenance panel to allow access to the decontamination source for maintenance or replacement. The air decontamination maintenance panel does not require the Recessed Ceiling or Surface Decontamination System unit to be moved, removed, pivoted, hinged, altered, or removed or relocated in any way from installed mounted operating position for unit maintenance or replacing the decontamination source. 
     Room Luminaire—Dimming Capable 
     The Recessed Ceiling or Surface Decontamination System center Room Luminaire is preferably capable of dimming. 
     Indicator Light 
     The Recessed Ceiling and Surface Decontamination System preferably contains an indicator light to confirm when the internal air decontamination system is or is not working properly or requires maintenance. 
     Air Decontamination Source Power-Off Switch 
     The Recessed Ceiling or Surface Decontamination System preferably has a switch to shut down power to the internal decontamination chamber when the air decontamination access cover is opened or removed for access or maintenance. The switch may be manual, but it is preferably automatic, activating when the Room Luminaire, Drop Ceiling Tile in hinged frame, or Room Surface and Air Decontamination Luminaire are opened. 
     External Room Surface Decontamination Source 
     The Recessed Ceiling or Surface Decontamination System preferably includes a warning strobe light, flashing light, audible alarm, and/or another warning device, or combination of warning devices, when the unit switches from external visible light source to the optional external non-visible light source (UV) for room decontamination. 
     Occupancy Sensor 
     The Recessed Ceiling or Surface Decontamination System optional External Room Surface and Air Decontamination Luminaire will contain occupancy sensors, thermal sensor, or motion sensor devices to control lighting when the room is occupied versus unoccupied. The sensor may be passive infrared, ultrasonic, dual passive infrared and Ultrasonic or other type of sensors known in the art. 
     Visual Warning Feature 
     The Recessed Ceiling or Surface Decontamination System optional External Room Surface and Air Decontamination Luminaire will contain visual warning feature such a strobe, strobe light, or other means as an indicator that the Room Surface and Air Decontamination Luminaire is in use. 
     Online Monitoring 
     The Recessed Ceiling or Surface Decontamination System preferably includes an online or other type monitoring system, on site or remote, which alerts installation facility or others that system that is working properly or is not working properly and requires maintenance.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     It is an object of the present invention to provide a ceiling-mounted decontamination unit with an internal decontamination source, with air intake and exhaust, which creates air movement through the unit&#39;s internal air decontamination chamber, duct, or enclosure to decontaminate and circulate room air effectively when the unit is installed into or onto a ceiling. This ceiling-mounted decontamination unit draws air into system from room below, decontaminates the air inside the chamber (enclosure), and exhausts air directly into the room below (drawing air upward into the air intake and exhausting the air downward into the room directly from the unit). 
     Permanently (Non-Moveably) Installed Into Recessed Ceiling 
     The ceiling-mounted decontamination unit is designed to be installed in a fixed, permanent, non-moveable manner into or onto recessed ceilings, drop ceiling, Inverted T-Bar Ceiling, Grid Ceiling, or other known type of suspended ceilings as well as onto or into non-recessed or plaster or sheetrock ceiling in areas such offices, hospitals, hallways, health care facilities, and other locations where air decontamination is desired. 
     Provision For Room Ceiling Tile, Luminaire, Or Room Surface Decontaminttion Luminaire 
     The ceiling-mounted decontamination unit contains a provision, preferably between the intake aperture and exhaust aperture or vent grill covers, designed to couple a Ceiling Tile in frame when no luminaire is needed, Room Luminaire for room lighting, or a Room Surface and Air Decontamination Luminaire for decontaminating room surfaces and air in the room or area where the unit is installed. 
     Ceiling Tile, Luminaire, Room Decontamination are Hingable or Pivoting 
     The Ceiling Tile, Room Luminaire, and Room Surface and Air Decontamination Luminaire coupled to the ceiling-mounted decontamination unit provision, are designed to hinge or pivot directly from the ceiling-mounted decontamination unit housing in a downward direction, toward the room floor, for maintenance, removal, and replacement, as well as provide access to the electrical raceway and Air Decontamination Maintenance Panel located on the decontamination chamber in the housing&#39;s internal space located behind the installed Ceiling Tile, Room Luminaire, and Room Surface and Air Decontamination Luminaire. This allows for all maintenance, replacement, removal, or any service from below the installed unit without moving or disengaging the unit housing from the ceiling grid in any way. 
     Internal Decontamination Source 
     The ceiling-mounted decontamination unit contains an internal decontamination system that is designed to draw room air into the system&#39;s internal decontamination chamber, where a decontamination source (Ultraviolet-C, Germicidal, Light Emitting Diode (LED), fluorescent, Ozone, or any other decontamination source) kills airborne pathogens in the room air as the air travels through the system&#39;s internal decontamination chamber making direct contact with the internal decontamination source. In the preferred embodiment, the one or more decontamination source(s) located within the decontamination chamber is positioned parallel with the air flowing through the chamber to increase the exposure time required for effective decontamination. Orienting the decontamination source parallel with the air flow increases the exposure time between the air in the chamber and the decontamination source. Greater exposure allows for more effective pathogen decontamination. Positioning the decontamination source in a parallel orientation with the air flow significantly increases the effectiveness of the germicidal source and the decontamination process verses orienting the decontamination source oriented in a position perpendicular with the air flow path through the decontamination chamber. The air makes direct and continued contact with the germicidal source as the air travels through the chamber. The decontaminated air exits the decontamination chamber and exits the unit directly back into the same room. 
     Room Surface and Air Decontamination Source 
     The ceiling-mounted decontamination unit may also contain a Room Surface and Air Decontamination Luminaire consisting of germicidal ultraviolet light (UV-C), Germicidal, Ozone, Sonic, Ultrasonic or known decontamination source designed to destroy pathogens on surfaces or in air as they come into contact with the Room Surface Decontamination Luminaire source. The Room Surface Decontamination Luminaire may consist of Light Emitting Diode (LED), fluorescent, germicidal, ultraviolet (UV-C), Ozone, or any other known decontamination source. 
     Source of Invisible Light Less than 400 nm 
     Both the internal Air Decontamination source and Room Surface and Air Decontamination Luminaire source are preferably “invisible light” less than 400 nm in wavelength. The lighting may be LED, fluorescent, germicidal, ultraviolet (UVC), ozone or other decontamination-type source or other lighting known in the art. 
     UV-C, Germicidal, Led, Sonic, Ultrasonic, Ozone as Decontaminating Sources 
     Currently, UV-C (Ultraviolet-C) in fluorescent-type discharge linear tubes with bi-pin or quad-pin base is the most effective decontamination system on the market with wavelengths of approximately 254 nm (254 nanometers). The preferred wavelength for the application is 254 nm-270 nm, which is believed to be the wavelength for maximum pathogen destruction. LED technology allows UV source to produce various wave lengths, producing wavelengths with greater pathogen decontamination ability. UV-C is a pathogen-killing light source that is unsafe for human contact. A decontamination source using UV-C is not visible light, so it would be dangerous to humans, mostly eyes and skin, if not treated safely. However, other methods of destroying bacteria, such as sound or ultrasound technology, and ozone may be used to destroy pathogens. In that case, the decontamination source would not be light (UV spectrum based), but sound based of air/gas-based and implementing the system and device of the present invention would simply involve replacing the UV-C light decontamination source with the sound, ultrasound based decontamination source or an ozone source. 
     With reference to  FIGS.  1 - 6   , the preferred embodiment of the present invention achieves this goal with a housing  1 , which includes attached ends  21 , being substantially rectangular for installing the unit directly onto a recessed ceiling grid or T-Bar  37 , also referred to as suspended ceiling, T-Bar Ceiling, Inverted T-Bar Ceiling, Grid Ceiling, or other known references. The housing  1  is adapted to be placed directly on the Recessed Drop Ceiling Grid “T-Bar”  37  as well as into or onto a plaster ceiling or other Non-Drop Ceiling applications inside a room. The ends  21  includes provisions, build in Hurricane Clips  22  designed to interlock the housing  1  with the ceiling grid  37  to prevent the housing from moving or dislodging from the grid ceiling  37  after installation. The ends  21  also include pry-out provision tabs  55  designed to fold or bend away from the end  21 , toward the ceiling, and provide additional provisions for support cable or support wire that secure the housing  1  directly to the facility structure to prevent the unit from dislodging or disengaging from the ceiling grid  37  after installation. 
     The housing  1  interior space  1   b  provides a mounting surface or raceway and electrical raceway cover  38  in which the internal components  39  of the Recessed or Surface Germicidal Decontamination System are mounted, including an internal air decontamination chamber  15 , intake aperture  2   a  and exhaust aperture  2   b , electrical raceway  40 , means for driving air  47 , and other required devices. 
     Decontamination Chamber/Duct 
     The internal space  1   b  of housing  1  also contains at least one decontamination duct or chamber  15  consisting of a vertical intake duct  12   a , decontamination chamber base  26  and chamber cover  28 , and vertical exhaust duct  12   b  located within the housing  1 . The decontamination chamber or duct  15  is positioned to extend the length of the housing  1  for greater exposure time to the decontamination source  16  in the chamber  15 . The room air  19  is drawn through the air intake aperture  2   a , by the system&#39;s means for driving air  47  which are preferably air fans  61 , and into the system&#39;s internal decontamination chamber  15  where the air  14  in the chamber  15  travels across one or more air deflectors  64  extending perpendicular across the chamber designed to create a stirring and swirling effect that causes an unsteady movement of air in the chamber. The air in the chamber  14  comes in direct contact with the decontamination source  16 , oriented in a direction that is perpendicular with the direction of the air path  14  traveling through the decontamination chamber for proper and effective decontamination. The decontaminated air exits the internal decontamination chamber  15  by way of the unit&#39;s exhaust aperture  2   b  where the decontaminated air returns to the same room, directly from the unit  20 , without the need for additional fans, ductwork, or HVAC equipment. The system&#39;s internal decontamination chamber  15  contains an opening  27  with a removable maintenance panel  18  designed for maintenance to the chamber  15  and the internal decontamination source  16  including replacing the decontamination source  16 . 
     Internal Decontamination Source 
     At least one internal decontamination source  16  is placed, attached or mounted into the decontamination chamber  15  positioned parallel with the air  14  flow to increase the exposure time between the decontamination source  16  and air  14  flowing through the chamber  15  for effective decontamination, located inside the internal space  1   b  of the housing  1 . Also contained in the internal space  1   b  of the housing  1  are the means for driving air  47  through the decontamination chamber  15 , wherein the air  14  is decontaminated by the at least one internal decontamination source  16  when the air  14  passes through the decontamination chamber  15 . The means for driving air  47  are preferably air fans  61 , but they could be other means for driving air. Thus, with reference to  FIG.  3   , the means for driving air  47  take room air  19  into the internal space  1   b  of the housing  1 , through the intake aperture  2   a  and drive the air  19  into the decontamination chamber  15 . When the at least one internal decontamination source  16  is active, pathogens and bacteria are killed or disabled when air  14  is passing through the decontamination chamber  15 . 
     Means for Driving Air 
     The means for driving air  47  then exhaust decontaminated air  20  from the internal space  1   b  of the housing  1  through the exhaust aperture  2   b . The means for driving air  47  may include optional air filters  13 , such as, for example particular matter, HEPA, or other known filters. The directional arrows  19  show the path of air  19  flow that enters the chamber  15  through the intake aperture  2   a  and the directional arrow  20  shows the path of the decontaminated air  20  flow that exits the system exhaust aperture  2   b . The directional arrows  14  show the path of the air  14  flow across the air deflectors  64  and the decontamination source  16  located within the decontamination chamber  15 . The intake aperture  2   a  and/or the exhaust aperture  2   b  of the preferred embodiment include a hinge  7  designed to engage and secure the intake aperture  2   a  and exhaust aperture  2   b  to the hinge provision  7   a  in the housing. The intake aperture  2   a  and exhaust aperture  2   b  are secured to the housing by a latch mechanism  8  designed to engage in the latch slot  8   a  to allow intake aperture  2   a  and exhaust aperture  2   b  to hinge or pivot open and/or to detach from housing  1  to enable easy access to the means for driving air  47  as well as air filters  13  for maintenance and/or replacement. The means for driving air  47 , preferably fans or fan bank  61 , are modular and connected together with fan bracket  62  that includes an enclosure for the fan power supply  63 . 
     Hingable Lighting
