Abstract:
An illumination device for the simulation of neon lighting comprises a leaky waveguide rod having a light-emitting lateral surface and a first set of one or more point light sources positioned adjacent one or both ends of the waveguide rod, the attenuation of light along the length of the waveguide rod being controlled such that light emitted from the lateral surface of the waveguide rod has essentially the same intensity over the length of the waveguide rod.

International Classification:
F21V021/00
US Classification:
362219, 362249, 362224, 362241
Abstract:
An illumination device for simulating neon of a predetermined design includes a substantially rigid power control board, a light source, at least one sidewall, and a waveguide. Light entering the lower lateral surface of the waveguide from the adjacent light source is directed along at least a portion of the length of the waveguide before being emitted from the light-emitting lateral surface of the waveguide, resulting in an essentially uniform light intensity pattern over its entire light-emitting surface. The control board is preferably a printed circuit board, prepopulated with multiple point light sources which are electrically connected to one another and are secured to and arranged in a predetermined design on the control board.
Illumination Device For Simulating Neon Lighting Through Use Of Fluorescent Dyes

International Classification:
F21V 21/00
US Classification:
362 84, 362219, 362231
Abstract:
An illumination device simulates neon lighting and allows for emission of light in colors that cannot ordinarily be achieved by use of LEDs alone through the incorporation of a light color conversion system into the illumination device. This light color conversion system comprises an intermediate light-transmitting medium tinted with a predetermined combination of one or more fluorescent dyes. Light emitted from the light source of the illumination device is directed into the intermediate light-transmitting medium and interacts with the fluorescent dyes contained therein. This light is partially absorbed by each of the fluorescent dyes of the intermediate light-transmitting medium, and a lower-energy light is then emitted from each of the fluorescent dyes and into the light-receiving surface of the waveguide. Thus, selection of appropriate combinations of dyes results in various colors being emitted from the illumination device.

US Classification:
315200A, 315185 S, 315312, 315323, 362800, 362806
Abstract:
A cuttable illumination device has a first lamp, a second lamp, a current source element, and a voltage breakdown element connected such that the first lamp may be removed from the device without affecting the function and performance of the remaining portion of the illumination device. Additional lamps may be added to the device in conjunction with additional voltage breakdown elements to form a string of lamps where any number of lamps may be removed without affecting the function and performance of the remaining portion of the device. The device may have a waveguide member and a housing, creating a cuttable illumination device for simulating neon lighting.

Assignee:

International Classification:
F21V 3/04
US Classification:
362311, 362355
Abstract:
An illumination device generally comprises a housing, a light source, and a scattering member. The housing includes a base portion and a side wall, which collectively defines an interior cavity with an open end having a predetermined shape. A light source is positioned within the interior cavity, along with an electric connecting member adapted to connect the light source to a remote power source. A scattering member having substantially the same predetermined shape as the open end of the housing is positioned adjacent the light source at the open end of the interior cavity. The scattering member has a light-emitting surface and is composed of a material which causes light entering the scattering member to be directed through a portion of thereof before being scattered and emitted, such that a substantially uniform light pattern is perceived along the light-emitting surface of the scattering member in the predetermined shape.

F21V 21/00
US Classification:
36224904, 36224902, 362278
Abstract:
An illumination device includes a flexible and substantially rod-like member having a predetermined length with a light-receiving surface and a light-emitting surface and an elongated light source extending along and positioned adjacent the light-receiving surface of the rod-like member, such that light entering the rod-like member from the elongated light source and through the light-receiving surface is preferentially scattered, thus causing a light intensity pattern that appears substantially uniform along the light-emitting surface of the rod-like member.

US Classification:
362520
Abstract:
A vehicle lamp assembly includes a housing having an inner reflective surface with predetermined optics and an outer surface. The inner and outer surfaces extend between proximal and distal ends. A lens is attached to the distal end of the housing. The lens and the inner reflective surface bound an enclosed chamber of the assembly. The assembly further includes a heat sink subassembly. The subassembly includes a heat sink and an electronic module. The electronic module has PCB electronics and at least one LED coupled in electrical communication with one another. The subassembly is mounted to the proximal end of the housing externally from the enclosed chamber.
Clip Unit And Edge Mounted Light Emitting Diode (Led) Assembly Comprising A Clip Unit
A clip unit and an edge mount light emitting diode (LED) assembly comprising a clip unit. The clip unit provides a mounting structure for mounting a light source, such as an LED, to an edge of a printed circuit board (PCB). A surface mount LED, for example, can thus be easily mounted to the edge of the PCB so as to project light in a direction normal to the edge surface of the PCB, instead of the typical mounting orientation that allows for the projection of light normal to the primary surface of the PCB. The clip unit includes an anode retention clip and a cathode retention clip which are electrically isolated from one another within an insulative housing portion.
