20110317406 | STRUCTURE OF SAFETY LED (LIGHT-EMITTING DIODE) LIGHTING TUBE - A safety LED lighting tube has a light cover, a base, a circuit board, and two electrical connectors. The light cover has a semi-circular hollow body made of a moldable material and has two side edges extending inwards and recessed to form rail channels. The base has a semi-circular body made of a moldable material and has a lower surface from which two hooked flanges project for slidable engagement with the rail channels formed on the side edges of the light cover. Ribs are formed on inward edges of the hooked flanges. The circuit board is received between and is supported by the ribs formed on the inward edges of the hooked flanges of the lower surface of the base. The circuit board has at least one LED. The electrical connectors are respectively mounted to opposite ends of the base and are electrically connected to the circuit board. | 12-29-2011 |
20120032574 | STRUCTURE OF LED (LIGHT-EMITTING DIODE) LIGHTING BULB - A structure of LED (Light-Emitting Diode) lighting bulb has a fin base, a pillar, a circuit board, an electrical connector, and a cover. The fin base forms a bore extending through a central portion and the bore has an inner circumferential surface forming an internal thread. The pillar has an outer circumferential surface forming an external thread, and the pillar is received and retained in the bore through threading engagement. The circuit board is mounted to an end of the pillar, and the circuit board carries an LED and conductor wires. The electrical connector is recessed to form a hollow configuration having an inside surface forming threading, and is coupled to the pillar through threading engagement while electrically connected to the conductor wires. The cover is mounted to the fin base. The mounting arrangement of the pillar and circuit board facilitates replacement of the circuit board and maintenance. | 02-09-2012 |
20120262915 | LED (LIGHT-EMITTING DIODE) LAMP WITH LIGHT REFLECTION - The present invention is primarily related to a LED (Light-Emitting Diode) lamp with light reflection, which provides both the forward and the backward illumination via the configuration of reflection plate with one side or both sides regularly distributed with a plurality of protruding or hollow geometric spatial blocks, for example, pyramids or cones to enable both light transparency and reflection, and thus enlarges the practical space of prior LED lamp illumination and provides more utility and convenience. | 10-18-2012 |
20130194805 | LED LIGHTING STRUCTURE - The present invention relates to an LED lighting structure, which includes a plurality of lighting units arranged and mounted to a base. Each lighting unit includes a seat, which has a surface to which a plurality of heat dissipation fins is mounted and an opposite surface to which a circuit board is attached. The circuit board includes a plurality of light-emitting diodes. The lighting units are arranged to allow the light-emitting diodes to face outward. In this way, all the light can be projected outward or toward a direction where lighting is desired so that no light would be wasted and the lighting efficiency and the convenience of use are improved. | 08-01-2013 |
