20110280020 | ILLUMINATION STRUCTURE AND LAMP TUBE STRUCTURE FOR GENERATING SPECIFIC DIRECTIONAL LIGHT SOURCES - An illumination structure for generating specific directional light sources includes a substrate unit, a light-emitting unit and a lens unit. The substrate unit has at least one substrate body. The light-emitting unit has a plurality of light-emitting elements disposed on and electrically connected to the substrate body. The lens unit has a plurality of lens modules sequentially abutted against each other and disposed on the substrate body. Each lens module has a lens frame disposed on the substrate body and a plurality of protruding lens elements separated from each other by a predetermined distance and integrally formed on the lens frame, the protruding lens elements respectively correspond to the light-emitting elements, and each protruding lens element has at least one concave portion formed on a top side thereof and above each light-emitting element and at least two protrusion portions respectively integrally connected to two opposite sides of the concave portion. | 11-17-2011 |
20110199768 | ASSEMBLED LED LAMP STRIP STRUCTURE AND LED LAMP HAVING THE SAME FOR CONTINUOUS LIGHTING - An assembled LED lamp strip structure for generating continuous lighting includes a substrate unit, a light-emitting unit and a packaging unit. The substrate unit has a plurality of substrate bodies sequentially and electrically connected to form a strip shape. The light-emitting unit has a plurality of linear light-emitting arrays respectively disposed on and electrically connected to the substrate bodies. Each linear light-emitting array has a plurality of light-emitting elements, and light beams generated by each light-emitting element are unobstructively projected outward. The packaging unit has a plurality of packaging bodies respectively disposed on the substrate bodies and respectively covering the linear light-emitting arrays, and the length of each packaging body is substantially the same as the length of each substrate body. | 08-18-2011 |
20110103053 | LED Lighting Device - The LED lighting device includes a tubular housing, a light emitting unit, and a reflector. The tubular housing has an accommodating space. The light emitting unit is disposed in the accommodating space and has a plurality of light emitting diodes. The reflector is disposed in the accommodating space and has a wing-shaped reflecting portion. The reflecting portion faces the light emitting unit for reflecting the light source emitted from the light emitting diodes to the lateral directions of the tubular housing. As a result, the light source can be converted to a specific direction. Compare to the fluorescent lamps, the present invention has higher illumination efficiency and a longer operating life. The volume of the lamps and the cost are saved. | 05-05-2011 |
20100219441 | LIGHT EMITTING DIODE PACKAGE STRUCTURE - An LED package structure and an LED packaging method are disclosed. The LED package structure includes a substrate, an LED unit and a transparent holding wall. The LED unit is electrically connected and located on the surface of the substrate. The transparent holding wall that corresponds to the LED unit is formed on the surface of the substrate, and has a receiving space. The LED unit is received in the receiving space. By utilizing the transparent holding wall, the colloid is controllably received in the receiving space and uniformly spread on the surface of the LED unit and around the LED unit. Thereby, the quantity of the colloid is easily controlled, and the LED package structure has a wide lighting angle due to the light emitted from the LED unit can pass through the transparent holding wall. | 09-02-2010 |
20100128485 | CUSTOM ASSEMBLY LIGHT-EMITTING MODULE - A custom assembly light-emitting module includes a base unit, a light-emitting unit and a lens unit. The base unit has a heat-dissipating base and two first retaining structures extending upwards from two opposite lateral sides of the heat-dissipating base. The light-emitting unit is detachably disposed on the heat-dissipating base. The lens unit has a lens and two second retaining structures formed on two opposite lateral sides of the lens, wherein the lens unit is detachably disposed over the light-emitting unit by matching the two first retaining structures and the two second retaining structures. Hence, the base unit, the light-emitting unit and the lens unit can be replaced according to the user's different requirements. | 05-27-2010 |
20090135602 | Lighting unit, receptacle unit, and assembly thereof - An assembly of a lighting unit and a receptacle unit includes at least one receptacle unit and at least one lighting unit. The receptacle unit has an outer housing provided with at least one first connection portion and at least one second connection portion electrically connected to the first connection portion in the outer housing. The lighting unit is electrically connected to one of the first and second connection portions of the receptacle unit, so that the lighting unit and the receptacle unit can be independently rotated in relation to each other along a connection axis thereof. | 05-28-2009 |
20090040782 | LED LIGHTING DEVICE - An LED lighting device includes a light pipe and a support portion. The light pipe includes a light emitting diode module inside and two first fastening portions on an outer wall thereof. A support portion secures the light pipe and provides a rotatable function for the light pipe. The support portion further includes a clamp and a base member. A clamp has two second fastening portions at opposite sides thereof. The second fastening portions engage with the first fastening portions. The clamp further includes a strip hollow slot. A base member includes a pair of positioning portions for holding an outer wall of the clamp, wherein a fastener is led through the strip hollow slot and fastened on the base member. The clamp slides relative to the base member along the strip hollow slot such that the light pipe rotates relative to the base member. | 02-12-2009 |
20080198590 | EXTENSIBLE LIGHT SHADE - A male terminal cap and a female terminal cap are mounted on the two ends of a strip light shade to form an extensible strip light shade. Electrical contacts are formed in the terminal caps for electrical coupling when two light shades are connected through mechanical coupling of the terminal caps. | 08-21-2008 |
