LEDs have been widely used to mark particular areas, illuminate dark areas, illuminate equipment, enhance the appearances of vehicles, etc. An LED is a semiconductor diode made of gallium arsenide, gallium phosphide, gallium nitride, silicon carbide, or the like, according to the color, the luminance and the intensity. LEDs convert electric energy efficiently into spontaneous and non-coherent electromagnetic radiation at visible and near-infrared wavelengths by electro-luminescence at a forward-biased pn junction. Upon being biased at the avalanche breakdown region, the pn junction forces an LED to emit visible light rays.

LEDs are very rugged and durable, exhibiting extremely long life because they emit light without heat, with no consumable filaments or gasses, having no voids, and perform with little regard for environmental conditions. In addition, LEDs are physically small, do not require high voltages to operate and consume minimal power compared with other active light sources. However, LEDs have several drawback characteristics that must be considered in their use. LED light output is highly directional, e.g., their viewing angle is narrow. Typical viewing angles are on the order of an included angle of only 20 degrees up to rare angles of 45 degrees. Viewed 'head-on', within their viewing angle, LEDs can appear very bright. But viewed outside of their viewing angle, LEDs quickly dim and disappear. Although not a problem with cosmetic or indicator applications, this characteristic severely limits LED use in practical or functional lighting. Until recently, LEDs were not a bright light source. This has changed, bringing LEDs into the arena of functional lighting applications, but the viewing angle restrictions of LEDs have remained.

The present invention are LED tube light housings configured to control and orient the lateral position of inserted LEDs on a wiring harness. An LED tube light housing according to the invention includes a first end, a second end, an inner surface, and an outer surface. The housing may be manufactured from rigid or flexible material. First and second sections are generally formed inside the housing.

The first section is configured in the form of a cavity for providing a vertical orientation of one or more LEDs. At least the top of the first section, e.g., the cavity, is transparent, translucent, or the like, to permit light emitted from LEDs contained therein to pass therethrough. The remaining portion of the housing may be transparent, translucent, opaque, or a combination thereof. The second section is configured to contain therein electrical components of the wiring harness. The wiring harness may include LEDs, fuses, resistors, wiring, and wiring splices. No printed circuit board portions are included in the wiring harness. The housing may also include a socket covering for one end, and may include a plug covering for the other end to enable multiple housings to be interconnected. The housing may also include a molded end cap.

One example of an LED tube housing is generally configured so a cross-section of the first section is generally U-shaped and is inverted, and cooperates with the second section that has a cross-section that is generally rectangularly shaped. The first section is configured to slidingly receive one or more LEDs.

Another example of an LED tube housing is generally rectangularly shaped. This housing is configured so a cross-section of the first section is generally rectangularly shaped, and cooperates with the second section that has a cross-section that is generally rectangularly shaped. The first section is configured in the form of two vertical walls that are spaced from each other by a distance that permits slidingly receiving one or more LEDs.

This housing also includes laterally extending portions from the top of the first section. These laterally extending portions may be configured in the form of hooks to permit the housing to be snapped onto a supporting member.
