Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to the field of recessed lighting systems which utilize either light emitting diodes (“LEDs”) or fluorescent lighting to provide non-glaring interior lighting. 
     2. Description of the Prior Art 
     In general, the concept of utilizing LEDs and/or fluorescent lights in recessed lighting fixtures has been known. However, the source of illumination is frequently visible, making for an unattractive source of lighting. 
     In the prior art, there have been various lighting fixtures which provide direct lighting. However, in most of these cases, the source of illumination is frequently visible to the individuals in the room in which the light is being used. Another embodiment includes a fluorescent lamp and a lens having prismatic elements for distributing the light. There are also some light fixtures which include parabolic fixtures in the light. 
     The most common source of indoor lighting, especially for business uses, has been a fluorescent lighting fixture. One problem with fluorescent lighting fixtures is sometimes they emit light which is too bright for the area. 
     Another disadvantage that is found in traditional parabolic and prismatic troffers is the presence of distracting dynamic changes in brightness level and patterns as seen by a moving observer in the architectural space. 
     There have been various sources of solutions to resolve the problems with the prior art. One example is found in U.S. Pat. No. 7,229,192 issued to Mayfield, III et al. on Jun. 12, 2007, for “LIGHT FIXTURE AND LENS ASSEMBLY FOR SAME”. In that patent, the disadvantages of light fixtures using brighter light sources by providing a configuration that appears to the viewer as though it has a source of lower brightness, but which otherwise permits the light fixture to advantageously and efficiently distribute the light generated by the selected lamp such as T5 lamp was allegedly resolved. The light fixture of that invention reduces directing direct light glare associated with high brightness light sources used in direct or indirect light fixtures. While the advantages of this patent are certainly of benefit, there is still significant room for improvement to improve the ability to reduce brightness and glare of sources of illumination, not only from fluorescent bulbs, but also from a source of light coming from light emitting diodes (“LEDs”). 
     SUMMARY OF THE INVENTION 
     The present invention is a recessed lighting fixture which can utilize either an LED recessed lighting fixture which includes a multiplicity of LED boards which have a multiplicity of LEDs thereon, or a fluorescent light source. The LED boards and/or fluorescent lights are shrouded by a diffuser lens basket so that light from the LEDs or fluorescent bulbs shining through the diffuser is dispersed to reduce glare and visibility of the source of light. 
     The present invention relates to a light fixture for efficiently distributing light emitted by a light source into an area to be illuminated. The invention includes a light reflector assembly that supports the light source. A significant innovation of the present invention is that the light reflector assembly is straight and is neither concave nor convex but instead, provides a straight angular reflector which serves to improve the light source emission from LEDs as well as fluorescent bulbs. 
     The light fixture also includes a lens assembly positioned with respect to the source of illumination, which lens assembly is removably affixed in the manner as will be described hereinafter. In the preferred embodiment, the fixture includes two parallel lenses which are spaced apart and cover separate LED boards or separate fluorescent tubes. 
     In one embodiment of the present invention, the reflector assembly of the light fixture includes a base member that extends longitudinally between spaced edges along a longitudinal access. At least a portion of the base member can form a reflective surface which is preferably a straight non-curved reflecting surface. The light fixtures is typically higher up in the structure so that the illumination can be dimmed by the reflector assembly and lens as set forth hereinafter. 
     It is an object of the present invention to provide an LED recessed lighting fixture which has the illumination from the LEDs shining through a diffuser which can be made of frosted acrylic material or perforated metal so that the illumination appears to come from a fluorescent light. 
     It is an additional object of the present invention to provide an access door in the top of the fixture so that access to a driver or ballast retained within the fixtures can be provided from the top of the fixture. 
     It is also an object of the present invention to provide an access door in the top of the fixture so that access to an emergency ballast or emergency battery retained within the fixture can be provided from the top of the fixture. 
     It is also an object of the present invention to provide a single driver or diffuser within the body of the fixture where access can only be gained from below the fixture. 
     It is an additional object of the present invention to incorporate the above novel features into a fixture which utilizes fluorescent light bulbs as the source of illumination. 
     Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims. 
     The present invention is an LED direct recessed lighting fixture and is also a direct recessed fluorescent lighting fixture for indoor lighting which includes a pair of diffuser lens baskets and reflectors. The fixture can be in various sizes. The preferred embodiment for the present invention has a generally square shape with a given length and width which by way of example can be 2 feet by 2 feet. 
     In the embodiment where the present invention LED direct recessed lighting fixture is designed to mimic a fluorescent light, it includes an LED fixture which is shrouded in a frosted acrylic or perforated metal diffuser to defuse the light emitted from the LEDs. Alternatively, the present invention is also a direct fluorescent lighting fixture. 
     Referring to  FIGS. 1-21 , there is illustrated the embodiments of the present invention which are generally square shaped and can be approximately 2 feet long by 2 feet wide. The LED direct recessed lighting fixture  10  has a first lengthwise sidewall  12 , a second parallel oppositely disposed lengthwise sidewall  14 , a first transverse front wall  16 A, a second transverse wall or rear wall  48  and a top surface or wall  80  which form a generally square shaped object. The front wall  16  has a top opening  18  and interior edge  20 . Top surface or wall  80  has a first opening  82  which joins opening  18  in front wall  16 . One of the unique innovations of the present invention is a first access door  30  having a top section  32  with an interior edge  34 , the top section extending to a transverse section  35  having a lower edge  36  into which are formed a pair of spaced apart fastening members or teeth  38  and  40 . The interior edge  34  of top section  32  of access door  30  is affixed to hinge  34 A an  34 B (See  FIG. 8 ) where top access door  30  rotatably opens about hinges  34 A and  34 B. The lower edge  36  of transverse section  35  is removably affixed to interior edge  20  of first sidewall  16  by teeth  38  and  40 . Referring to  FIG. 3 , the fixture  10  contains a driver or ballast  42  which is affixed to the interior surface  31  of access door  30 . By incorporating first rapid access door  30 , access to the driver  42  can be rapidly achieved from above the fixture  10  without having to dismantle the fixture from below. 
     Parallel oppositely disposed rear wall  48  has a top opening  50  and interior edge  52 . Top wall  80  has a second opening  84  which joins opening  50  in second sidewall  48 . A second unique innovation of the present invention is a second access door  60  having a top section  62  with an interior edge  64 . The interior edge  64  of top section  62  of access door  60  is affixed to a hinge  65  where top access door  60  rotatably opens about hinge  65 . The lower edge  66  of transverse section  67  is removably affixed to interior edge  52  of second transverse wall  48  by teeth  68  and  70 . Referring to  FIG. 3 , the fixture  10  contains an emergency ballast or driver  72  which is affixed to the interior surface  65 A of access door  60 . By incorporating second rapid access door  60 , access to the emergency ballast  72  can be rapidly achieved from above the fixture  10  without having to dismantle the fixture from below. 
     When a main ballast or driver  42  and emergency ballast or diver  72  is desired, they are on opposite sides of the fixture to provide balance. This is also illustrated in the cross-sectional view of  FIG. 11 . Sometimes, only one ballast is desired. In that design, the ballast  42 A is centered in the fixture as illustrated in  FIG. 20  and this is only a main ballast and there is no emergency ballast in this design. 
     One key innovation of the present invention is that it is an LED recessed light which is designed to mimic a fluorescent light. Referring to  FIGS. 9A through 13 , the invention contains two spaced apart pairs of LED boards. By way of example only referring to  FIG. 13 , the present invention includes two LED boards  400  and  410  along one LED section  420  affixed to the underside or interior wall  86  of top wall  80 . Both LED boards  400  and  410  are horizontally oriented and spaced apart so that the two LED boards extend for the entire width of the fixture  10 . There is a second spaced apart parallel set of LED boards  430  and  440  along a second LED section  450  affixed to the underside or interior wall  86  of top wall  80 . 
     Alternatively, by way of example only referring to  FIG. 13A , the present invention includes at least one LED board  400 A having at least one LED  410 A along one LED section  420 A affixed to the underside or interior wall  86  of top wall  80 . The at least one LED board  400  is horizontally oriented and spaced apart so that the at least one LED board extends for the entire width of the fixture  10 . There is a second spaced apart parallel at least one LED board  430 A having at least one LED  440 A along a second LED section  450 A affixed to the underside or interior wall  86  of top wall  80 . 
     It will be appreciated that while two LED boards  400 ,  410 ,  430  and  440  are illustrated in each respective set  420  and  450 , it is within the spirit and scope of the present invention to have at least one LED board being horizontally disposed. The body comprising sidewalls  12  and  14  and front wall  16  and rear wall  48  and top wall  80  all act as a heat sink for the LEDs. 
     One of the unique innovations of the present invention is that each set of the LED boards  400 ,  410 ,  430  and  440  respectively are shrouded in a frosted acrylic or perforated metal diffuser lens  200  or  200 A (see  FIG. 3 ) which is in the shape of a longitudinal basket extending the entire interior width of the fixture  10  and which serves to diffuse the light from the LEDs. 
     The key physical components of the fixture  10  are illustrated in the exploded views of  FIGS. 9A and 9B . The main body  100  comprises the top surface  80  and interior surface  86  of top surface  80 . Top surface  80  extends to a first vertical interior transition wall  90  which in turn extends at a first angled wall  92  which extends at an angle relative to top surface  80  and terminates in a lower grooved wall  94  having a gap  96  between wall  94  and angled wall  92 . Top surface  80  also extends to a second interior transition wall  102  which in turn extends to a second angled wall  104  which extends at an angle relative to top wall  80  and terminates in a lower grooved wall  106  having a gap  108  between wall  106  and second angled wall  104 . First angled wall  92  and second angled wall  104  are mirror images of each other. First angled wall  92  has pair of spaced apart first channel receiving or gripping members  91  and  93  (see  FIG. 13 ). Second angled wall  104  has a pair of spaced apart second channel receiving or gripping members  105  and  107 . While the number  80  has been designated as the “top surface” throughout the text, it will be appreciated that it can also be referred to as the “top wall” for support in the claims. 
     Referring to  FIG. 9B , the fixture  10  further comprises a V-shaped ballast cover  120  having a first angled wall  122  extending to a first vertical interior transition wall  124 . A pair of spaced apart second channel receiving or gripping members  126  and  128  are located at the junction where the first angled wall  122  contacts the first vertical interior transition wall  124 . The V-shaped ballast cover  120  also has a second angled wall  130  extending to a second vertical transition wall  132 . A pair of spaced apart first channel receiving or gripping members  134  and  136  (see  FIG. 13 ) are located at the junction where the second angled wall  130  contacts the second vertical interior transition wall  132 . 
     First angled wall  92  and second angled wall  104  are straight—that means that they are neither convex or concave. Front wall  16  and rear wall  48  are each perpendicular to top wall  80 —that means they are not at any angle other than 90 degrees relative to top wall  80 . 
     Referring to  FIG. 12A , the light from the LEDs is transmitted through the diffuser lens  200 . An additional improvement is the incorporation of a wavy interior surface  202  on the exterior of the diffuser lens  200 . The wavy interior surface causes the lights from the LEDs to bounce off the wavy surface and provide a smooth warm illumination glow. The wavy surface also serves to hide the spot locations where illumination from the LEDs are emitted. 
     As best illustrated in  FIG. 12A , the diffuser lens  200  is arc shaped having a first arcuate sidewall  210  which terminates in a bent hook end  220  having a channel or gap  230  within the hook end  220 . The diffuser lens  200  also has a parallel second arcuate sidewall  240  which terminates in a bent hook end  250  having a channel or gap  260  within the hook end  250 . The diffuser lens  200  has a width “W 1 ” which can range from approximately three (3) inches to approximately eight (8) inches. A first reflector support assembly  300  includes first receiving or gripping members  91  and  93  inserted into channel  230  of diffuser lens  200  and second gripping members  126  and  128  from first angled wall  122  of V-shaped ballast cover  120  are inserted into channel  260 . The first angled wall  92  is supported by interior transition wall  90  affixed to interior surface  86  of top surface  80 . V-shaped ballast cover  120  is affixed to interior surface  86  of top surface  80  by screws such as screws  120 A,  120 B,  120 C,  120 D,  120 E and  120 F illustrated in  FIG. 9B . To remove diffuser lens  200 , an inward force is applied to remove channel  230  from gripping members  91  and  93  or channel  260  is removed from first gripping members  126  and  128 . The diffuser lens  200  covers LED boards  400  and  410 . 
     Referring to  FIG. 9B , parallel diffuser lens  200 A covers LED boards  450 A and  450 B. As best illustrated in  FIG. 12B , the diffuser lens  200 A is arc shaped having a first arcuate sidewall  210 A which terminates in a bent hook end  220 A having a channel or gap  230 A within the hook end  220 A. The diffuser lens  200 A also has a parallel second arcuate sidewall  240 A which terminates in a bent hook end  250 A having a channel or gap  260 A within the hook end  250 A. The diffuser lens  200 A has a width “W 2 ” which can range between approximately three (3) inches and approximately eight (8) inches. A second reflector support assembly includes second channel receiving or gripping members  134  and  136  from second angled wall  130  of V-shaped ballast cover  120  inserted into channel  230 A of diffuser lens  200 A and second gripping members  105  and  107  from second angled wall  104  are inserted into channel  260 A. The second angled wall  104  is supported by interior transition wall  102  affixed to interior surface  86  of top surface  80 . V-shaped ballast cover  120  is affixed to interior surface  86  of top cover  80  by screws such as screws  120 A,  120 B,  120 C,  120 D,  120 E and  120 F illustrated in  FIG. 9B . To remove diffuser lens  200 A, an inward force is applied to remove channel  230 A from gripping members  134  and  136  or channel  260 A is removed from gripping members  105  and  107  of second angled wall  104 . The diffuser lens  200 A covers LED boards  430  and  440 . 
     Referring to  FIG. 11A , the straight first angled wall  92  extends at a downward approximately 45 degree angle and terminates in a bottom end  92 A having a lower horizontal section  92 B extending to a first vertical section  92 C which extends to a second upper horizontal section  92 D which extends to a second upper vertical section  92 E. The bottom of sidewall  14  rests on upper horizontal section  92 D and against upper vertical section  92 E. 
     Referring to  FIG. 11B , similarly the straight second angled wall  104  extends at a downward approximately 45 degree angle and terminates in a bottom end  104 A having lower horizontal section  104 B extending to a first horizontal section  104 C which extends to a second upper horizontal section  104 D which extends to a second upper vertical section  104 E. The bottom of sidewall  12  rests on upper horizontal section  104 C and against upper vertical section  104 E. 
     Since the LED boards are horizontally oriented, light will shine through the respective diffusers  200  and  200 A and give a glowing effect to the fixture  10 . As a result, through the use of the diffusers  200  and  200 A, the LEDs mimics a fluorescent light. The addition of the wavy interior surface  202  on the diffuser lens (and  200 B on diffuser lens  200 A) provides the added advantages previously discussed. 
     The driver  42  through which the system is powered is affixed to the lower surface of access door  30  as previously discussed and can be accessed from above through access door  30 . In addition, to gain access from below, diffuser  200  is removed as previously described and the respective reflector assembly  300  will have to be removed. 
     On the opposite side of the fixture is the emergency battery pack or emergency ballast  72  which is affixed to the lower surface of access door  60  as previously discussed which enables access from above to the emergency battery pack  72 . In addition, to gain access from below, diffuser  200 A is removed by an inward force to remove the diffuser  200 A and reflector assembly  310  will have to be removed. 
     If the ballast  42 A is in the center affixed to interior surface  86  of surface  80 , then the V-shaped ballast cover  100  will have to be removed to gain access to the center diffuser. 
     The purpose of the emergency battery pack or emergency ballast is to light some of the LEDs in the event power goes out so that an individual will have lighting to escape from a building should power go out. 
     The LEDs  400 ,  410 ,  430 , and  440  are primarily white light but it is also within the spirit and scope of the present invention to have them in color and have them in different colors. It is believed that the fact that the LEDs on a board being in tandem in alternating rows is a new innovation of the present invention. 
     The pair of diffusers  200  and  200 A are unique to the present invention. 
     Either or both of the drivers  42  and  72  or individual driver  42 A can be a dimming driver. Alternatively, it is possible to have a dual level switch where two hot leads are brought in each switch independently that would turn on and off a subgroup of one of the subsets of the LED boards. By way of example, a dimming LED switch would have a dimming LED driver which would have a rotating switch wherein the amounts of light emitted from each of the LEDs would be varied and could be brighter or dimmer. Alternatively, the fixture can have dual level switch where the LEDs on boards  400  and  430  can be turned on with one switch and the LEDs on boards  410  and  440  can be turned on with a separate switch. This is only one example because any variation of a number of switches turning on the LEDS and respective boards is within the spirit and scope of the present invention. Therefore, it is within the spirit and scope of the present invention to have at least one board turned on with a switch and it is also possible to have two or three boards turned on with one switch and an alternatively two or three boards turned on with a second switch. Therefore, a user can use the full power mode the dimming mode on the driver. 
     The diffusers  200  and  200 A are each primarily frosted acrylic although it can also be perforated metal. For the LEDs, there are different shades of white. There are a warm white, a cool white, daylight and possibly colored LEDs. Therefore, the LEDs  400 ,  410 ,  430  and  440  can be warm white, cool white, daylight, colored and true white. 
     In the case of the emergency battery pack or emergency diffuser  72 , it will go on if the power goes out and at least a certain subset of the LEDs will be lit. The special circuit design will be a nickel cadmium battery for the emergency battery pack  72  so it will last at least 90 minutes and the idea is to preserve battery life so therefore, the emergency battery will only be lighting one subset of LEDs to provide light so that someone can exit the building in case there is an emergency. 
     Referring to  FIGS. 1 and 2 , the top surface  80  has an access door  80 D to gain access to the junction box for wiring. The top surface  80  also has knockouts  80 A,  80 B and  80 C for electrical connection means to affix a central ballast. 
     Another key innovation of the present invention is that the 2×2 dawn lighting volumetric fixture can also retain fluorescent bulbs instead of LED boards. The LED boards are replaced with fluorescent bulbs  700  and  710 . Referring to  FIGS. 12C ,  12 D and  17  through  20 , the invention contains two spaced apart fluorescent bulbs  700  and  710 . Both fluorescent bulbs  700  and  710  are horizontally oriented so that the two fluorescent bulbs each respectively extend for the entire width of the fixture  10 . 
     One of the unique innovations of the present invention is that each of the fluorescent bulbs  700  and  710  are respectively shrouded in a frosted acrylic or perforated metal diffuser lens  200  or  200 A which is in the shape of a longitudinal basket extending the entire interior width of the fixture  10  and which serves to diffuse the light from the fluorescent bulbs. 
     The key physical components of the fixture  10  are illustrated in the exploded views of  FIGS. 9A and 9B . The main body  100  comprises the top surface  80  and interior surface  86  of top surface  80 . Top surface  80  extends to a first vertical interior transition wall  90  which in turn extends at a first angled wall  92  which extends at an angle relative to top wall  80  and terminates in a lower grooved wall  94  having a gap  96  between wall  94  and angled wall  92 . Top surface  80  also extends to a second interior transition wall  102  which in turn extends to a second angled wall  104  which extends at an angle relative to top wall  80  and terminates in a lower grooved wall  106  having a gap  108  between wall  106  and second angled wall  104 . First angled wall  92  and second angled wall  104  are mirror images of each other. First angled wall  92  has pair of spaced apart first channel receiving or gripping members  91  and  93 . Second angled wall  104  has a pair of spaced apart second channel receiving or gripping members  105  and  107 .

Similarly, as illustrated in  FIGS. 19 and 20 , sockets  720  and  730  are on opposite sidewalls  12  and  14  to retain fluorescent bulb  710 . Diffuser  200 A covers fluorescent bulb  710 . 
     The driver  42  through which the system is powered is affixed to the lower surface of access door  30  as previously discussed and can be accessed from above through access door  30 . In addition, to gain access from below, diffuser  200  is removed as previously described and the respective reflector assembly  300  will have to be removed. 
     On the opposite side of the fixture is the emergency battery pack or emergency ballast  72  which is affixed to the lower surface of access door  60  as previously discussed which enables access from above to the emergency battery pack  72 . In addition, to gain access from below, diffuser  200 A is removed by an inward force to remove the diffuser  200 A and reflector assembly  310  will have to be removed. 
     If the ballast  42 A is in the center affixed to interior surface  86  of cover  80 , then the V-shaped ballast cover  120  will have to be removed to gain access to the center diffuser. A single ballast  42 A is most commonly used with fluorescent bulbs, but it is within the spirit and scope of the present invention to have two diffusers  42  and  72  also used with fluorescent bulbs. 
     The purpose of the emergency battery pack or emergency ballast is to light some of the LEDs in the event power goes out so that an individual will have lighting to escape from a building should power go out. 
     The fluorescent bulbs  700  and  710  are primarily white light but it is also within the spirit and scope of the present invention to have them in colors and have them in different colors. 
     The pair of diffusers  200  and  200 A are is unique to the present invention. 
     Either or both of the drivers  42  and  72  or a single driver  42 A can be a dimming driver. Alternatively, it is possible to have a dual level switch where two hot leads are brought in each switch independently that would turn on and off a subgroup of one of the subsets of the fluorescent bulbs. By way of example, a dimming switch would have a dimming driver which would have a rotating switch wherein the amounts of light emitted from each of the fluorescent bulbs would be varied and could be brighter or dimmer. Alternatively, the fixture can have dual level switching where a respective one of the fluorescent bulbs  700  can be turned on with one switch and the fluorescent bulb  710  can be turned on with a separate switch. This is only one example because any variation of a number of switches turning on the fluorescent bulbs. Therefore, it is within the spirit and scope of the present invention to have at least one fluorescent bulb turned on with a switch. Therefore, a user can use full power mode or dimming mode on the driver. 
     The diffusers  200  and  200 A are each primarily frosted acrylic although it also can also be perforated metal. 
     In the case of the emergency battery pack or emergency diffuser  72 , it will go on if the power goes out and at least a certain subset of the LEDs will be lit. The special circuit design will be a nickel cadmium battery for the emergency battery pack  72  so it will last at least 90 minutes and the idea is to preserve battery life so therefore, the emergency battery will only be lighting one subset of LEDs to provide light so that someone can exit the building in case there is an emergency.
