| 20120044676 | Structure of light-emitting diode (LED) lamp - A structure of color temperature adjustable LED lamp includes a substrate, on which a plurality of cold white light LEDs and a plurality of additional LEDs are respectively mounted. The additional LEDs give off lights having a wavelength of 580-660 nm. The cold white light LEDs give off lights that are mixed with the lights from the additional LEDs to realize adjustment of the result color temperature as desired. | 02-23-2012 |
| 20110317409 | Structure of lighting device - A structure of lighting device includes a heat dissipater having opposite edges respectively forming a guide slot and a groove. A substrate board has an edge received and retained in the guide slot and an opposite edge forming a mounting hole. A fastener is received through the mounting hole to tightly engage the groove so as to fix the substrate board to the heat dissipater. No pre-machining of thread tapping is needed to form inner-threaded holes first. The structure of lighting device offers advantages in respect of simple structural arrangement, efficient manufacturing and production, reduced labor and material used, and lowering of costs. | 12-29-2011 |
| 20110304271 | Light-emitting diode (LED) protection structure - A light-emitting diode (LED) protection structure includes an LED portion and a protection portion. The protection portion includes a fuse and a Zener diode connected in series. The protection portion is electrically connected to the LED portion in parallel but opposite in direction. As such, the LED protection structure can effectively protect the LEDs and the Zener diode from being damaged to thereby reduce costs. | 12-15-2011 |
| 20110298378 | Light-emitting diode (LED) protection structure - A light-emitting diode (LED) protection structure includes an LED portion and a protection portion. The protection portion includes a fuse and a Zener diode connected in series. The protection portion is electrically connected to the LED portion in parallel but opposite in direction. As such, the LED protection structure can effectively protect the LEDs and the Zener diode from being damaged to thereby reduce costs. | 12-08-2011 |
| 20110292646 | Structure of lighting device - A structure of lighting device includes g a hood, a heat dissipater, at least one substrate board, and a fastener. The hood forms a receiving space, at least one fitting slot, and at least one heat dissipation opening. The fitting slot is located inside the receiving space. The heat dissipation opening is defined in a circumferential surface of the hood. The heat dissipater is received in the receiving space. The heat dissipater forms at least one guide section. The guide section opposes the fitting slot and is received in the fitting slot. The substrate board is electrically connected to at least one light-emitting diode. The substrate board is coupled to the heat dissipater. The heat dissipation opening allows for air circulation for removing heat generated by light-emitting diodes. Further, the heat dissipation opening is formed to have a width W less than 3mm, and the heat dissipater is arranged to be spaced from a circumferential surface of the hood by a distance greater than 6mm. | 12-01-2011 |
| 20090237940 | ADJUSTABLE LIGHTING DEVICE - An adjustable lighting device having a main body, a light generation device inserted into a receptacle, a movable lens, a base electrically connected to the light generation device, and an adjustor cover rotatably mounted to and covering the outside of the main body so that rotation of the adjustor cover causes the lens to extend/retract within the receptacle so that the extension/retraction of the lens can be controlled by the rotation of the adjustor cover for realizing focus adjustment. | 09-24-2009 |
