Abstract: A street lamp includes a shell, a mount, a radiation unit and an illumination unit. The shell includes an opening defined therein. The mount is located in and connected to the shell. The radiation unit is connected to the mount. The illumination unit is connected to the radiation unit. The illumination unit can emit light that can travel through the opening.

Abstract: A roadside lamp with a heat dissipating design is disclosed. The roadside lamp of the present invention comprises a seat portion and a plurality of light emitting units. A panel is fitted to the seat portion and the light emitting units are fitted to the panel. The back portion of the panel is tightly fitted to a heat dissipating fin-like portion. A pair of rails extends outwardly from the fin-like portion. The pair of rails may be used to connect the roadside lamp with a surface in a place such as a tunnel. For example, a track may be provided on the top portion of a tunnel; therefore, a plurality of the roadside lamps may be fitted to the track in a tidy manner. The pair of rails allows each roadside lamp to be fitted to the track and thus, the location of the lamp may be adjusted.

Abstract: An LED assembly includes a circuit board, one or more LED modules, one or more positioning plates and a heat dissipating plate. One or more openings are disposed in the circuit board. An electric terminal is provided on either side of each hole. A circuit pattern is provided on the circuit board to allow a parallel connection of each electric terminal. The heat dissipating plate is installed under the circuit board. Several connective holes are provided in the heat dissipating plate. In assembly, each hole is aligned with the corresponding LED module and the positioning plate is installed on top of the corresponding LED module. Several fasteners are used to fixedly connect the positioning plates, LED modules, circuit board and heat dissipating plate together. Therefore, the LED modules may be securely fixed.

Abstract: The background light module for LCD utilizes LED as its light source, a single light generating LED die is grouped in an arcuately shaped oval lens to form an LED light source unit, and several LED light source units constructed as such are combined to form a background light module on a support arm to illuminate the LCD so as to create a brilliant and comfortable lighting effect.
