Abstract:
An ultra-high efficiency underwater light for attracting marine life having radially arranged facets supporting light emitting diodes (LEDs) that project a large perimeter of light underwater. A water cooling system allows the high powered LEDs to operate at sustained peak levels without sacrificing service life. A light bifurcating structure causes a central portion of water to illuminate in a different color than the color of the outer perimeter portion of water. A tire valve stem located on the underwater light is used to remove moisture bearing air and to also pressurize the light with a non-corrosive gas. Antifouling circuitry automatically cycles the underwater light on and off multiple times during periods of non-use. Smart circuitry communicates through a series of blinks and accepts commands from a user through a power cord.

No. 13/655,107 filed Oct. 18, 2012, entitled, “SYSTEMS AND METHODS FOR UNDERWATER LIGHTING.” 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    This invention relates, generally, to underwater dock lights. 
         [0004]    2. Background Art 
         [0005]    The light emitting unit in many conventional underwater lights are incandescent bulbs that are not energy efficient. Metal hydride lighting systems require the use of bulky transformers that are also not energy efficient compared to compact fluorescent lighting (CFL) or high intensity light emitting diode (LED) systems. Transformers make the assembly more costly and are unsightly. Incandescent, metal hydride, and CFL bulbs use hazardous high voltage A/C current. When these bulbs are used in underwater lights, the use of a ground fault circuit interrupt (GFCI) is recommended for safe operation. GFCI&#39;s add additional cost to an underwater light system. LED systems can operate with non-hazardous, low voltage D/C current which is a much safer alternative to the prior art A/C systems. Moreover, incandescent bulbs, CFL bulbs, and metal hydride bulbs have a short life expectancy in comparison to LEDs. 
         [0006]    High intensity LEDs used in light systems produce concentrated heat at each LED. Although an underwater light assembly has a relatively stable external temperature due to submersion, without a way of dissipating the heat from a concentrated point of each LED, the high intensity LED will overheat and become damaged. 
         [0007]    There are several challenges to overcome with using high intensity LEDs in an underwater light system. One challenge being the need for the LED to be in contact with a heat sink capable of sufficiently transferring heat. The problem with a heat sink in an underwater light is determining how to cool the heat sink. Thus, there is a need for an improved method of cooling LEDs inside an underwater light. 
         [0008]    Currently, most prior art underwater lights on the market operate in about ten feet or less of water. These underwater lights have a light emission that is configured to beam away from the light fixture housing, resulting in the light source emitting a beam of light. In shallow water, the light beaming upward results in an underwater light having a small diameter of light being illuminated. Thus, there is a need for an improved, underwater light that directs the light not only upward, but radiating outward to produce a large diameter of light being illuminated in shallow water. 
         [0009]    Prior art underwater lights are not energy efficient compared to the diameter of light they produce. Thus, there is a need for an underwater light that produces a brighter light and a larger diameter of light in a body of water. This is more desirable to an observer and attracts more marine life to the site. More particularly, a brighter light is more effective at penetrating murky water. 
         [0010]    Prior art underwater lights illuminate the surrounding water a single color. Thus, there is a need for an improved underwater light that illuminates the surrounding water with multiple colors simultaneously. 
         [0011]    Prior art underwater lights incorporate a compression nut to attempt to seal an electrical cord to a light housing. However, the constant underwater tugging motion and temperature variations result in expansion, contraction, and fatigue of the electrical cord against the compression nut. This constant tugging from the water movement and temperature variations results in a high failure rate of sealing an electrical cord to a light housing, allowing water to enter the light and damage the electrical components. 
         [0012]    Some prior art underwater lights are designed to accept an electrical cord through an opening penetrating the light housing. Liquid resin is applied to the light housing&#39;s opening to create a seal. The problem with the prior art light housing is that as the resin hardens to a solid state, it begins to shrink and pull away from the inner perimeter wall of the light housing opening. 
         [0013]    More particularly, due to the liquid resin shrinking and pulling away from the inner perimeter wall of the light housing opening, the underwater light will leak water in a gap formed between the inner perimeter wall opening of the light housing and the hardened resin. When water leaks into an underwater light, the integrity of the unit is compromised and the unit fails. Thus, there is a need for an improved sealing structure that produces a permanent, water-tight seal. 
         [0014]    However, in view of the prior art considered as a whole at the time the present invention was made; it was not obvious to those of ordinary skill in the pertinent art how the identified needs could be fulfilled. 
       SUMMARY OF THE INVENTION 
       [0015]    The long-standing but heretofore unfulfilled need for an underwater light that is adapted to be internally water cooled by a thermally conductive housing having LED circuit boards mounted at an angle to produce a large diameter of light and a housing having an integrated surrounding water sealing structure which also includes improvements that overcome the limitations of prior art underwater lights, is now met by a new, useful, and non-obvious invention. 
         [0016]    The novel underwater light includes a transparent cover positioned over a light fixture housing. The transparent cover is adapted to fit over a light emitting unit including, but not limited to, an LED. Any light emitting unit is within the scope of this invention. The light fixture housing has an integrally formed sealing structure located opposite a light emitting unit. The sealing structure is defined by a primary sealing surface at the base of the sealing structure located opposite a secondary sealing surface at the peak of the sealing structure. The cavity at the base of the light fixture housing is located adjacent to the primary sealing surface at the base of the sealing structure. The cavity at the peak of the light fixture housing is located adjacent to the secondary sealing surface at the peak of the sealing structure. A primary sealing structure opening in the sealing structure accommodates an electrically conductive element including, but not limited to, a wire, a port tube, or a light socket adapted to penetrate the sealing structure opening from a point external of the light fixture housing. The primary sealing structure opening has a liquid resin in contact with the sealing structure and the electrically conductive element. This electrically conductive element is connected in electrical communication with a light emitting unit. The secondary sealing structure opening accepts an electrically conductive element including, but not limited to, an electrical cord. 
         [0017]    A liquid resin substantially fills the cavity at the base of the light fixture housing and comes into contact with the sealing surface at the base of the sealing structure. The liquid resin substantially fills the cavity at the peak of the light fixture housing and comes into contact with the sealing surface at the peak of the sealing structure. When the liquid resin hardens to a solid state its unitary structure conforms to the primary sealing surface at the base of the sealing structure and the secondary sealing surface at the peak of the sealing structure. This results in the electrically conductive element and the sealing structure to be permanently sealed from an external water source. 
         [0018]    This improved integrally formed sealing structure with a primary sealing surface opposing a secondary sealing surface for the liquid resin to conform to as it hardens results in a sealing structure producing a permanent, water-tight seal. An electrical power cord is permanently sealed regardless of a gap forming between the inner perimeter wall opening of the light housing and the hardened resin. By constructing this sealing structure, the use of a liquid resin and the shrinking nature of resin during hardening, makes such a sealing structure produce a permanent, water-tight seal. This is due to the constriction of the hardened resin around the surfaces of the sealing structure. 
         [0019]    This novel invention also includes an improved transparent cover being one color and having a transparent lens being a different color. More particularly, the preferred combination is a colored lens to emit a dark colored light located in the center portion of the light projected through the water and a clear cover to emit a white light or lighter color to the outer perimeter of light projected through the water. This combination attracts marine life to the center dark color beam of light while the outer lighter color perimeter light allows spectators to view marine life more vividly. Though multi-color underwater lights aid in attracting and viewing marine life, they are also aesthetically pleasing to spectators. The transparent cover may have a lens that is permanently attached to the transparent cover. Additionally, the transparent cover may have a lens that is removable from the transparent cover. This removable feature is accomplished with the transparent lens having a transparent lens latching structure that is inserted into a transparent cover opening. 
         [0020]    The improved water cooling system dissipates the concentrated heat associated with LEDs to a point external of an underwater light, resulting in a substantially brighter light without damaging the LEDs. By having a stable way of cooling LEDs with water, the LEDs can be safely overdriven, producing a brighter light than they were originally designed to produce.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0048]    In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part hereof, and within which are shown by way of illustration specific embodiments by which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the invention. 
         [0049]    In a preferred embodiment,  FIG. 1  shows the underwater light  1  has light fixture housing  4 A located opposite transparent cover  2 . Light fixture housing  4 A has attaching structures  8 A and  8 B located on an end of the light fixture housing  4 A. Attaching structures  8 A and  8 B are configured to equally suspend underwater light  1  in a body of water. Underwater light  1  displaces a volume of water, causing underwater light  1  to be buoyant. Attaching structures  8 A and  8 B each have attaching structure opening  9 A and  9 B to receive an attaching element (not shown). The attaching element includes, but is not limited to; a rope, tether, tie strap, or a chain. Attaching structures  8 A and  8 B receive an attaching element connected to an anchor configured to suspend underwater light  1  in a vertical orientation when submerged in a body of water. 
         [0050]      FIG. 3  shows light fixture housing  4 A having secondary sealing structure opening  21  located on sealing structure  5  to receive an electrically conductive element (not shown). A liquid resin (not shown) is in direct contact with sealing structure opening  21  and primary sealing structure opening  13 , permanently sealing the electrically conductive element from surrounding water.  FIG. 4  shows, light fixture housing  4 A on which sealing structure  5  and support surface  6  are formed. Support surface  6  receives a pliable support material (not shown) that surrounds the light bulb (not shown). 
         [0051]      FIG. 25  illustrates one embodiment of housing  10  having valve stem opening  26  capable of removing or filling underwater light  1  with a gas including, but not limited to; an inert gas. An alternate embodiment not shown includes light fixture housing  4 A having a valve stem opening located thereon. It is also within the scope of this invention to evacuate underwater light  1  of all gas and to be left in a state of vacuum. The removal of air containing moisture eliminates the oxidation of internal electrical components. Additionally, pressurizing underwater light  1  allows the assembly to be post tested for potential leaks at the point of manufacture. Pressure inside the assembly also adds a counter force to the crushing effects of water at a depth. It is also within the scope of this invention to connect an opening of the light to a regulated and pressurized gas supply that would fill or release a gas inside of underwater light  1  to maintain a constant force against the crushing effects of surrounding water, even at extreme depths. Uses for the invention could branch out to marine exploration or construction. 
         [0052]    Underwater light  1  has antifouling circuitry (not shown) configured to automatically cycle a power interrupt circuit (not shown) to underwater light  1  “on” and “off” multiple times during periods of non-use. The frequency and duration of cycles will vary in differing conditions including, but not limited to, freshwater or saltwater. The antifouling circuitry includes, but is not limited to, a software program. It is also within the scope of the invention to include antifouling chemicals in the injection molding process of components including, but not limited to; transparent lens  3  or transparent cover  2 . Bright light and heat generated by underwater light  1  deters growth from attaching to transparent lens  3 , transparent cover  2 , and cooling surfaces of housing  10 . 
         [0053]    Underwater light  1  has smart circuitry (not shown) that can accept commands and communicate with a user through a series of light blinks or pauses between light blinks. The smart circuitry controls a power interrupt circuit (not shown) that powers a light emitting unit. A user can program the light to operate for a desired time span of each night by acknowledging a series of blinks from underwater light  1 . Each series of blinks indicate an “on” period of time or an “off” period of time per day. The user acknowledges a series of blinks from underwater light  1  by powering “off” the light after the desired series of blinks. The smart circuitry accepts the command associated with the desired series of blinks prior to powering down. It is also within the scope of this invention for the user to cycle the power to the light, causing the smart circuitry to accept commands. For instance, a user could cycle the power “on” and “off” three times within thirty seconds, which would cause the smart circuitry to operate “on” twelve hours and “off” twelve hours each day. The smart circuitry can also monitor and communicate faults including, but not limited to, a high temperature condition and also shut down the light if it overheats. It can indicate overheating to a user through a series of flashes until a user rectifies the cause of overheating. Though the above methods of communicating are preferred embodiments, all methods of communicating through the power supplied to underwater light  1  and controlling other features are within the scope of the invention. 
         [0054]      FIG. 2  shows transparent cover  2  is located opposite light fixture housing  4 A. Transparent cover  2  is positioned over a light bulb (not shown).  FIG. 4 . shows light fixture housing  4 A having support surface  6  that receives a pliable support material (not shown) that surrounds the light bulb not shown. The pliable support material is wider than the distance between the bulb and inner wall  4 B of light fixture housing  4 A, such that the pliable support material is compressed between the light bulb and inner wall  4 B of the light fixture housing  4 A. The pliable support material thus squeezes the light bulb to support the bulb. Additionally, the pliable support material is forced against inner wall  4 B of light fixture housing  4 A. The supporting of the light bulb aids in protecting the light bulb from breaking when underwater light  1  is tossed into the water. The squeezing of the light bulb also prevents the unscrewing from its socket due to the constant motion of currents. The pliable support material also creates a water tight barrier. 
         [0055]    Transparent cover  2  is located opposite light fixture housing  4 A. Transparent cover  2  is positioned over a light bulb. Transparent cover  2  has a support surface (not shown) that receives a pliable support material (not shown). The pliable support material is in contact with a portion of the bulb. The pliable support material is compressed between the light bulb and inner wall  4 B of the light fixture housing  4 A. 
         [0056]    Light fixture housing  4 A is located opposite housing  10  (not shown). Light fixture housing  4 A has support surface  6  that receives a pliable support material (not shown).

The pliable support material is configured to be compressed between port tube  40  and inner wall  4 B of light fixture housing  4 A. The pliable support material forms a water tight seal between light fixture housing  4 A and housing  10 . 
         [0057]      FIG. 24  shows transparent cover  2  is positioned over housing  10 . Transparent cover  2  has support surface  6  that receives a pliable support material (not shown). The pliable support material is in contact with a portion of housing  10 . The pliable support material is configured to be compressed between housing  10  and transparent cover  2 . As shown in  FIG. 25 , housing  10  has chamber  31  formed from an interconnection of primary supporting surface  22 A, secondary supporting surface  22 B, tertiary supporting surface  22 C ( FIG. 9 ), and quaternary supporting surface  22 D ( FIG. 9 ).  FIG. 9  shows each of supporting surfaces  22 A,  22 B,  22 C, and  22 D are formed on chamber wall secondary side  33 . 
         [0058]      FIG. 8  shows internal cooling system  20  having housing  10  having primary chamber aperture  17  that is in direct contact with a surrounding water source. Primary chamber aperture  17  receives water and absorbs heat generated by light emitting units  19 A and  19  B through chamber wall primary side  32  and chamber wall secondary side  33  as shown in  FIG. 26 .

Primary chamber aperture  17  is configured to allow surrounding water to substantially fill chamber  31  and absorb heat from chamber  31  generated from light emitting units  19 A,  19 B,  19 C, and  19 D as shown in  FIG. 9 , sufficiently cooling light emitting units  19 A,  19 B,  19 C, and  19 D.  FIG. 9  depicts each of supporting surfaces  22 A,  22 B,  22 C, and  22 D are in thermal communication with light emitting units  19 A,  19 B,  19 C, and  19 D generating heat. Each of supporting surfaces  22 A,  22 B,  22 C, and  22 D supports at least one light emitting unit. 
         [0059]      FIG. 5  depicts transparent cover  2  being a first color having a permanently attached transparent lens  3  of a second color positioned over a light emitting unit.

         [0062]      FIG. 12  shows transparent cover  2  having two attaching structures  8 A and  8 B located on the end of transparent cover  2 . The two attaching structures  8 A and  8 B each have one attaching structure opening  9 A and  9 B to receive an attaching element. The attaching element includes, but is not limited to; a rope, tie strap, tether, or a chain. An alternate embodiment not shown includes two attaching structures  8 A and  8 B are located outboard of the perimeter of a primary chamber aperture  17  receiving surrounding water.

A user has the ability to remove air from the inside of underwater light  1  and to fill underwater light  1  with an inert gas. This prevents water droplets from condensation and building up on the inside surfaces of underwater light  1 , causing damage to circuitry inside the light. Internal pressure from within the light also aids in leak detection and leak prevention.

Each of supporting surfaces  22 A,  22 B,  22 C, and  22 D support a primary light emitting unit of a primary color  19 A,  19 B,  19 C, and  19 D and a secondary light emitting unit of a secondary color  19 E,  19 F,  19 G, and  19 H.  FIG. 7  shows primary light emitting unit of a primary color  19 A and  19 B and secondary light emitting unit of a secondary color  19 E and  19 F are oriented in an upper and lower position related to central axis  30  of internal cooling system  20 . 
         [0068]    As shown in  FIG. 23 , housing  10  has light bifurcating structure  27  having light bifurcating structure primary surface  35  located opposite light bifurcating structure secondary surface  16 . Light bifurcating structure  27  is positioned between primary light emitting unit of a primary color  19 A,  19 B,  19 C ( FIG. 9 ), and  19 D ( FIG. 9 ) and secondary light emitting unit of a secondary color  19 E,  19 F,  19 G ( FIG. 9 ), and  19 H ( FIG. 9 ). Light bifurcating structure  27  extends from a point substantially related to or connected to a surface supporting a primary light emitting unit of a primary color and a secondary light emitting unit of a secondary color. Light bifurcating structure  27  extends away from the point of contact of primary light emitting units of a primary color  19 A,  19 B,  19 C, and  19 D and secondary light emitting units of a secondary color  19 E,  19 F,  19 G, and  19 H extends to a point where light bifurcating structure  27  obstructs at least a portion of light from primary light emitting units of a primary color  19 A,  19 B,  19 C, and  19 D and a portion of light from secondary light emitting units of a secondary color  19 E,  19 F,  19 G, and  19 H. Light bifurcating structure  27  causes an outer perimeter of water to illuminate in a primary color and a central portion of water to illuminate in a secondary color. An electrical cord (not shown) is provided to be in electrical communication with light emitting units through power cord inlet  7  located on housing  10 . The electrical cord is connected to a power source. 
         [0069]    Transparent cover  2  is located over housing  10 . Housing  10  is constructed of a thermally conductive material.  FIG. 7  describes housing  10  having primary supporting surface  22 A at an angle between 0 degrees and 85 degrees in relation to central axis  30  of underwater light  1  ( FIG. 24 ). Housing  10  has secondary supporting surface  22 B at an angle between 0 degrees and 85 degrees in relation to central axis  30  of underwater light  1 . Housing  10  has tertiary supporting surface  22 C ( FIG. 9 ) at an angle between 0 degrees and 85 degrees in relation to central axis  30  of underwater light  1 . Housing  10  has quaternary supporting surface  22 D ( FIG. 9 ) at an angle between 0 degrees and 85 degrees in relation to central axis  30  of underwater light  1 . The optimal supporting surface angle is approximately 20 degrees in relation to central axis  30  of underwater light  1 . The angle range between 0 degrees and 85 degrees is to achieve a varying perimeter of light radiating from underwater light  1 .  FIG. 9  depicts primary supporting surface  22 A, secondary supporting surface  22 B, tertiary supporting surface  22 C, and quaternary supporting surface  22 D are each in thermal contact with light emitting units generating heat. 
         [0070]    Primary supporting surface  22 A, secondary supporting surface  22 B, tertiary supporting surface  22 C, and quaternary supporting surface  22 D are configured to form chamber  31  having a large diameter primary chamber aperture  17  located on one end of chamber  31 . As shown in  FIG. 10 , chamber  31  has a smaller diameter secondary chamber aperture  18  located at the opposite end of chamber  31 . Primary chamber aperture  17  receives surrounding water of an ambient primary temperature. One opening located at the end of chamber  31  has a diameter at least 10 percent larger or smaller than the opening located at the opposite end of chamber  31 . Depending on how tall chamber  31  is, the diameter of the larger opening will become exponentially larger as chamber  31  lengths are increased. As water absorbs the heat radiated from light emitting units, secondary chamber aperture  18  expels surrounding water from inside chamber  31  at a secondary temperature greater than the ambient primary temperature. Secondary chamber aperture  18  expelling heated water is determined by the orientation of underwater light  1 . Since hot water rises, the end of chamber  31  pointing toward the surface will generally expel the heated water. 
         [0071]    Transparent cover  2  is located over housing  10 . Housing  10  is constructed of a thermally conductive material. Housing  10  has primary supporting surface  22 A at an angle between 0 degrees and 85 degrees in relation to central axis  30  of underwater light  1 . Housing  10  has secondary supporting surface  22 B at an angle between 0 degrees and 85 degrees in relation to central axis  30  of underwater light  1 . Housing  10  has tertiary supporting surface  22 C at an angle between 0 degrees and 85 degrees in relation to central axis  30  of underwater light  1 . The optimal supporting surface angle is approximately 20 degrees in relation to central axis  30  of underwater light  1 . Primary supporting surface  22 A, secondary supporting surface  22 B, and tertiary supporting surface  22 C are each in thermal contact with a light emitting unit generating heat. Housing  10  can be configured to have or not have chamber  31 . All though not as efficient, housing  10  can be constructed primarily as a solid structure with a surface exposed to surrounding water. Housing  10  could also be constructed of a solid outer surface with its core filled with a thermally conductive material. 
         [0072]      FIG. 25  depicts a method of constructing underwater light  1  to enable a cooling operation between housing  10  and a surrounding water source. Housing  10  is provided and has a plurality of supporting surfaces each being at an angle between 0 degrees and 85 degrees in relation to central axis  30  ( FIG. 7 ) of underwater light  1 . A plurality of light emitting units are attached to the plurality of supporting surfaces. The plurality of supporting surfaces are located on chamber wall secondary side  33  that is not in contact with water. Transparent cover  2  is provided to enclose the portion of housing  10  having the plurality of supporting surfaces.  FIG. 21  shows chamber wall primary side  32  of housing  10  which is in contact with surrounding water. The surrounding water sufficiently cools light emitting units. 
         [0073]    These embodiments are illustrative of the invention and are not exhaustive thereof. As underwater light manufacturers add additional or different structures, still further structures may be required in future embodiments of the invention but all such future embodiments are within the scope of this invention. 
         [0074]    For example, underwater light  1  may have only one attaching structure (not shown). Thus, the single attaching structure would bridge an end of housing  10  having primary chamber aperture  17  to accommodate an attaching element. 
         [0075]    Underwater light  1  having two attaching structures  8 A and  8 B located on an end of housing  10  each have at least one attaching structure opening  9 A and  9 B to receive an attaching element. The attaching element includes, but is not limited to; a tether, tie strap, rope, or a chain, including, but not limited to being; tied, clipped, or snapped to attaching structure openings  9 A and  9 B. 
         [0076]    Thus, attaching structures  8 A and  8 B will connect with all currently known attaching elements and in view of this disclosure any future changes in attaching structures  8 A and  8 B can be met. 
         [0077]    Moreover, as mentioned, each embodiment of the illustrative embodiments will accommodate novel internal water cooling system  20 , regardless of the number of supporting surfaces and configuration of housing  10  therein. In order to form chamber  31  having angled supporting surfaces, there must be at least three supporting surfaces  22 A,  22 B, and  22 C. Although, not preferred, a cone shape without a flat supporting surface would also accommodate a plurality of supporting surfaces at an angle between 0 degrees and 85 degrees in relation to central axis  30  of underwater light  1  and also provide chamber  31 . 
         [0078]    For instance,  FIG. 26  shows housing  10  with chamber  31  having primary chamber aperture  17  located at the base end of chamber  31  and an opposite secondary chamber aperture  18  located at the peak end of chamber  31 , will incorporate internal water cooling system  20  ( FIG. 8 ). Surrounding water flows through chamber  31  by entering through primary chamber aperture  17 . Surrounding water contacts chamber wall primary side  32  and absorbs heat generated by light emitting units attached to chamber wall secondary side  33 . Heated water is expelled through secondary chamber aperture  18 . 
         [0079]    Although, not as effective as internal water cooling system  20 , a solid housing  10  not having chamber  31  will have a water cooling effect in which surrounding water comes into contact with an exposed surface of housing  10 . This surface will be in thermal communication with light emitting units generating heat. The surrounding water will absorb heat from housing  10 &#39;s surface in contact with surrounding water. 
         [0080]    In addition to the aforesaid embodiments of chamber  31  of housing  10 , light fixture housing  4 A includes multiple additional improvements as well. 
         [0081]    A first improvement as shown in  FIG. 3  is of light fixture housing  4 A having an integrally formed sealing structure  5  located opposite of a light emitting unit (not shown). Sealing structure  5  has an area for resin to contact two opposing surfaces: primary sealing surface  11  and secondary sealing surface  12  ( FIG. 4 ). An electrically conductive element is adapted to penetrate secondary sealing structure opening  21  from a point external of light fixture housing  4 A. When resin is applied to primary sealing structure opening  13  and secondary sealing structure opening  21 , primary cavity  14  at the base end of light fixture housing  4 A becomes filled with resin and primary sealing surface  11  is contacted by the resin. As shown in  FIG. 4 , secondary cavity  15  at the peak end of light fixture  4 A housing becomes filled with resin and secondary sealing surface  12  becomes surrounded by the resin. When the resin hardens to a solid state, it tightens around primary sealing surface  11  and secondary sealing surface  12  while pulling away from inner wall  4 B of light fixture housing  4 A. The electrically conductive element and sealing structure  5  are permanently sealed from an external water source. 
         [0082]    A second improvement of light fixture housing  4 A is shown in  FIG. 3  and has a primary sealing structure opening  13  to accept an electrically conductive element including, but not limited to, a light bulb, light socket, or an electrical cord. Light fixture housing  4 A has a secondary sealing structure opening  21  located at the base end of light fixture housing  4 A accepts an electrically conductive element including, but not limited to: an electrical cord. 
         [0083]    A third improvement as shown in  FIG. 10  includes internal water cooling system  20 . Housing  10  has chamber  31  that receives surrounding water at a primary ambient temperature through primary chamber aperture  17  located on the base end of chamber  31 . The water enters chamber  31  through primary chamber aperture  17  and cools the LEDs by absorbing heat generated by the LED&#39;s through chamber wall primary side  32  of housing  10 . The water exits the chamber through secondary chamber aperture  18  located at the peak end of chamber  31  at a secondary temperature greater than the ambient water primary temperature. By overdriving the LED&#39;s, a substantially brighter light is produced without risk of damaging the LEDs due to the efficiency of water cooling. It is also envisioned to have the peak of chamber  31  point opposite the surface of the water to illuminate toward including, but not limited to, the sea floor or a reservoir bottom. It is also envisioned to have underwater light  1  in a horizontal position having water forced through chamber  31  due to movement of a water vehicle or water pump. 
         [0084]    A fourth improvement of internal water cooling system  20  as shown in  FIG. 10  has primary chamber aperture  17  accepting surrounding water. The water then flows into chamber  31  where it comes into contact with chamber wall primary side  32  of housing  10  and absorbs heat generated from a light emitting unit. The greater temperature water rises and exits chamber  31  from secondary chamber aperture  18 . 
         [0085]    Another improvement produces a large diameter of light in shallow water. Housing  10  has at least three LED circuit board supporting surfaces each configured at an angle between 0 degrees and 85 degrees in relation to central axis  30  of underwater light  1  when suspended vertically underwater from an end of underwater light  1  opposite transparent cover  2 . This configuration allows the light from the LEDs to radiate outward and upward from underwater light  1  to produce a large diameter of light. 
         [0086]    Underwater light  1  is further improved as shown in  FIG. 2  by transparent cover  2  being a primary color and having transparent lens  3  located at the distal end of transparent cover  2  being a secondary color. Transparent cover  2  illuminates an outer perimeter of water in a primary color while transparent lens  3  illuminates a central portion of the water in a secondary color. This multi-color effect both attracts marine life and is esthetically pleasing to spectators. 
         [0087]    The transparent cover  2  is clear with white LED&#39;s and transparent lens  3  has a color other than clear. Marine life is attracted to the colored center beam of light and the white perimeter lighting illuminates the surrounding water for vivid visibility of marine life. 
         [0088]      FIG. 4  shows an improved support surface  6  is formed on inner wall  4 B of light fixture housing  4 A located opposite transparent cover  2  ( FIG. 1 ) which is positioned to cover a light bulb (not shown). This support surface  6  receives a pliable support material (not shown) including, but not limited to; foam or rubber. The pliable support material is in contact with a portion of a light bulb to prevent any shifting of the light bulb and also to create a seal to prevent water from entering light fixture housing  4 A. The pliable support material is configured to be compressed between a light bulb and an inner wall  4 B of light fixture housing  4 A. 
         [0089]    Support surface  6  has a location on transparent cover  2  that provides a surface for a pliable support material configured to be compressed between a light bulb and transparent cover  2  (not shown). 
         [0090]    Support surface  6  has a location on transparent cover  2  positioned over housing  10 . The pliable support material is configured to be compressed between housing  10  and an inner wall  4 B of light fixture housing  4 A (not shown). 
         [0091]    Support surface  6  has a location on transparent cover  2  positioned over housing  10 . The pliable support material is configured to be compressed between housing  10  and inner wall of transparent cover  2  (not shown). 
         [0092]    An important object of this invention is to provide underwater light  1  with the use of high powered LEDs by utilizing internal water cooling system  20  to absorb excessive heat. This heat absorption enables a stable environment for the LEDs to be overdriven and creates superior light penetration underwater. 
         [0093]    Another important object is to provide a permanently water tight sealing structure  5  that allows a hardened resin to tighten to opposing surfaces of primary sealing surface  11  and secondary sealing surface  12  ( FIGS. 3 and 4 ). 
         [0094]      FIG. 26  illustrates an improved housing  10  eliminates the need for light fixture housing  4 A. Housing  10  has a wider base that comes into contact with transparent cover  2  and is sealed by an O-ring or sealant in primary O-ring channel  38  that mates with secondary O-ring mating surface  37  of housing  10 .  FIG. 25  shows housing  10 &#39;s base has openings to receive fasteners including, but not limited to screws or rivets. Housing  10 &#39;s base has a power cord inlet  7  to receive an electrically conductive element. Housing  10  may have chamber  31  with one or two openings for internal cooling system  20  ( FIG. 8 ) or a structure with no opening (not shown) for a cooling system that transfers heat when surrounding water comes into contact with an exposed surface of housing  10 . 
         [0095]    Additional objects include, but are not limited to, the provision of underwater light  1  having an improved support surface  6  with a pliable support material, a plurality of circuit boards supporting light emitting units mounted on housing  10 &#39;s chamber wall secondary side  33  at an angle between 0 degrees and 85 degrees from central axis  30  to increase the perimeter of light emitted, an improved transparent cover  2  being a primary color having transparent lens  3  of a secondary color, a higher intensity light emitted providing improved light penetration underwater due to ultra-efficient water cooling of LEDs, light bifurcating structure  27  that is positioned between a set of LED&#39;s of a primary color and a set of LED&#39;s of a secondary color, antifouling circuitry (not shown) that deters growth from attaching to underwater light  1 , smart circuitry (not shown) that can communicate faults and settings to a user through multiple combinations of blinks from underwater light  1 , and valve stem opening  26  to add a gas to or remove a gas from underwater light  1 . 
         [0096]    These and other important objects, advantages, and features of the invention will become clear as this description proceeds. 
         [0097]    The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts that will be exemplified in the description set fourth hereinafter and the scope of the invention will be indicated in the claims.
