DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(15) Aspects of the invention are disclosed in the accompanying description. Alternate embodiments of the present invention and their equivalents are devised without parting from the spirit or scope of the present invention. It should be noted that like elements disclosed below are indicated by like reference numbers in the drawings.

(16) The waterproof light bulb assembly of the disclosed embodiments includes a bulb cavity configured to allow for the correct heat release provided by the plurality of LEDs. Excessive heat discharge can cause damage to the LED bulb. The LED modules inside the bulb generate heat. If there are too many LED modules, then the interior of the bulb overheats which causes the circuitry and other components within the bulb to fail. Too few modules, and the light bulb is too dim for use in an outdoor or wet environment. Further, the light bulb should resemble a conventional bulb. Thus, the disclosed embodiments provide a plurality of LED modules to emit enough light for use in chandeliers and other light fixtures but also account for the generated heat to avoid failures.

(17) It should be noted that the disclosed waterproof light bulb assembly may be used in any location, including outdoors in the rain or in inclement weather. The light bulbs do not require extensive maintenance. Unlike conventional light bulbs, the disclosed light bulbs resist corrosion from the elements and exposure. For example, a conventional upward-facing Edison light bulb may only last a short time being used outdoors before needing to be replaced. This failure rate precludes use of the Edison conventional bulb in remote or elevated locations as personnel would have to lower and replace the bulbs frequently.

(18) Although there are LED bulbs on the market, these devices do not look or illuminate like conventional incandescent light bulbs. The disclosed embodiments allow for a modern, energy efficient, all weather light bulb that is upward-facing and is cosmetically identical or looks similar to any traditional indoor candelabra light bulb. This feature may be important for set locations and the ambience being created by using a chandelier. Further, the LED light bulbs in accordance with the disclosed embodiments are applicable to wet location environments.

(19) The disclosed embodiments also allow for existing or even antique light fixtures to be retrofitted with the waterproof light bulbs. The disclosed light bulb assembly may fit different light bulb socket designs and dimensions. This benefit allows the disclosed light bulbs to fit many varieties of devices and fixtures, some of which are antiques in that they do not include the designs of modern light fixtures.

(20) The waterproof light bulb assembly in accordance with the disclosed embodiments includes LED modules as light sources and a hollow light bulb, or light bulb shell. The LED modules including a plurality of LEDs are installed in the light bulb assembly with the plurality of LEDs facing upwardly. The light bulb shell acts like that glass portion of a conventional light bulb. This appearance also is provided based on the configuration of the LED modules within the light emitting assembly. The LED light is not as soft as the light emitted in a conventional light bulb, and as the plurality of LEDs face upwardly, the LED light will shine in an upward direction. Conventionally, the light bulb shell is made frosted to let light pass through but not too frosted to diminish the lighting effects. The frosted light bulb shell helps reserving some emitting light inside of the light bulb to provide the appearance of a conventional light bulb. The disclosed embodiments provide a unique waterproof light bulb assembly in which the light bulb shell may be made of clear plastic. An additional lens is disclosed inside the light bulb shell to reflect and refract the light shone by the LED module to render the light bulb having an appearance of a conventional light bulb. In the disclosed embodiments, the bulb shell made be made of clear or frosted plastic.

(21) FIG. 1 depicts a waterproof light bulb assembly 100 according to the disclosed embodiments. Light bulb assembly 100 includes a plastic bulb shell 102 and a lens assembly 120.

Lens assembly 120 is located on the top of a light emitting assembly 104. Lens assembly 120 has a lens 122 in a shape of a pyramid, with cut-off-edge top surface 124 and a peak 126 on a bottom. Lens 122 may be made of a polycarbonate material or any appropriate material that allows a light to pass through. In use, a light beam emitted from light emitting assembly 104 will shine on lens 122 from below. Cut-off-edge top surface 124 and peak 126 of lens assembly 120 reflect and refracted the light beam emitted from light emitting assembly 104 to represent an appearance of a traditional candelabra light bulb.

(22) Lens 122 is located above light emitting assembly 104 and is apart from assembly 104 with a distance called a focal length. To do so, lens 122 is inserted on a top of hollow cylinder 128. The height of hollow cylinder 128 is determined to ensure that the light emitted from light emitting assembly 104 will travel to lens 122 and be reflected and refracted by lens 122, thereby a light bulb appearance most simulated to the conventional light bulb are generated.

(23) A detailed view of lens assembly 120 is illustrated in FIG. 2. As shown in FIG. 2, lens 122 is inserted on the top of hollow cylinder 128 with peak 126 toward the bottom of hollow cylinder 128. A lower end 130 of hollow cylinder 128 is designed narrower to have a smaller diameter than the rest of hollow cylinder 128. The diameter of lower end 130 matches an inner diameter of a bulb cap 106 so that hollow cylinder 128 can be inserted tightly in bulb cap 106.

(24) Light emitting assembly 104 includes components that emit light using LED modules. Preferably, light emitting assembly 104 includes a plurality of LEDs that are oriented upwards into plastic bulb shell 102.

(26) Lens assembly 120 is seated on the top of light emitting assembly 104 and is inserted in bulb cap 106. As describe above, lower end 130 of hollow cylinder 128 has a smaller diameter than the rest of hollow cylinder 128. Therefore, after lower end 130 of hollow cylinder 128 is inserted in bulb cap 106, the rest of hollow cylinder 128 will sit on bulb cap 106 to secure the position of lens assembly 120.

(27) Light bulb assembly 100 also includes socket 108 and mount 110. Socket 108 may receive bulb cap 106 and a threaded portion of light bulb shell 102. Socket 108 also may help attach the DC connector to a wire or power source in a secure manner. Socket 108 is secured to mount 110. Mount 110 is configured to fit light bulb assembly 100 to a variety of light fixtures.

(28) FIG. 3 depicts an exploded view of light bulb assembly 100 according to the disclosed embodiments. Light bulb shell 102, lens assembly 120, light emitting assembly 104, and bulb cap 106 may comprise waterproof light bulb 200 within assembly 100. Light bulb 200 may be a distinct component from socket 108 and mount 110. FIG. 3 also shows other components of assembly 100.

(29) As can be seen in FIG. 3, bulb shell 102, lens assembly 120, and light emitting assembly 104 fit into bulb cap 106 to create light bulb 200. Light bulb 200 is waterproof in that the plastic bulb shell, lens assembly 120, and secured fit between the shell and the bulb cap and the lens assembly 120 and the bulb cap does not allow water or other elements into contact with the LED modules. Further, as these materials are not comprised of metal, they may withstand exposure outside and to water. Preferably, light bulb shell 102, lens assembly 120, and bulb cap 106 are made of plastic. As disclosed below, light bulb shell 102, lens assembly, and bulb cap 106 are fitted to attach to each other in a secure manner.

(30) Some components of socket 108 are shown in more detail. Socket 108 includes socket housing 204.

Protrusion 404 also helps fit light bulb shell 102 with bulb cap 106.

(33) The interior of exterior threaded portion 302 may be referred to as mating part 406. Mating part 406 includes a tapered draft 408. Tapered draft 408 tapers inward along the length of mating part 406. Tapered draft 408 may tap at an angle between 0.5 to 3. Thus, the passage 410 of light bulb shell 102 to receive bulb cap 106 may get slightly thinner the further it goes towards shaped portion 301.

(34) Referring back to FIG. 4, DC connector 304 may be shown extending from the bottom surface of bulb cap 106 to resemble a conventional light bulb. This feature is disclosed in greater detail below. The size of light bulb shell 102 is important as well to accommodate the heat generated by light emitting assembly 104. Light bulb shell 102 may be about 20% larger than conventional light bulb shells to provide enough air and volume to accommodate the generated heat. This size may vary depending on the function of light bulb 200 and the amount of heat generated by light emitting assembly 104. This specified size also allows light bulb shell 102 to be made of plastic, which is waterproof.

(35) FIG. 6 depicts a cut-away view of bulb cap 106 according to the disclosed embodiments. As shown above, bulb cap 106 is circular to fit within light bulb shell 102.

As shown, light bulb 200 is secured in socket 108 using threaded portions 302 and 802. DC connector 304 is received within female connector 208 to provide a DC power receptacle for light emitting assembly 104. LEDs 608 are configured to illuminate upwards into light bulb shell 102. Screws 206 secure socket 108 to mount 110 while extended part 812 fits between arms 1008.

(54) It also may be shown that female connector 208 along with O-ring 202 provides a seal between socket 108 and light bulb 200. Positive and negative connectors 908 and 910, respectively, are shown extending outwards to be soldered to wires or connect to a power source for light bulb 200. All components are fitted to provide a waterproof seal that allows the disclosed waterproof light bulb assembly to be used outside and in wet conditions without exposing the circuits to the elements. Further, the light emitting assembly is configured to regulate the amount of heat generated so as to not overheat or damage the components. Once placed in the secure, waterproof fitting, the disclosed assembly does not need to be replaced or fixed for an extended period of time so that the disclosed assembly may be used in remote locations.

(55) It may be appreciated that the disclosed embodiments, including light bulb 102, waterproof light bulb assembly 100, and light emitting assembly 104 are comprised, or mostly comprised, of plastic materials. This feature is in contrast to conventional light bulbs using LEDs that are comprised, at least partially, of metal. These metal component bulbs may dissipate heat but are ill-suited for the disclosed embodiments as they are not able to withstand exposure to outdoors or wet conditions. The metal corrodes and rusts over time so that these conventional light bulbs cannot be used and causes damage to the light fixture. The disclosed embodiments, by regulating the generated heat, is able to use plastic components that can withstand outdoor and wet conditions.

(56) Further, as the light bulb assembly 100 includes a lens assembly 12 that reflects and refracts the light beam emitted from light emitting assembly 104, light bulb shell 102 does not need to made frosted and can be made of clear plastic. An upward-facing light bulb assembly that has an appearance of any traditional candelabra light bulb can thus be provided in accordance with the disclosed embodiments. The light bulb assembly of the disclosed embodiments can be used indoors and outdoors with a wet location environment.

(57) It will be apparent to those skilled in the art that various modifications and variations can be made in the disclosed embodiments of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention covers the modifications and variations of the embodiments disclosed above provided that they come within the scope of any claims and their equivalents.
