Abstract

The present invention discloses an LED lamp bar, which mounts a plurality of LEDs and comprises an extruded aluminum reflection back plate, at least one LED carrier plate, at least one driver, a transparent lamp cover, and two side plates. The LED carrier plate and driver are arranged on the extruded aluminum reflection back plate. The LED carrier plate mounts the LEDs. The driver is coupled to the LED carrier plate and drives the LEDs. The transparent lamp cover and two side plates are installed on the extruded aluminum reflection back plate to encase the LED carrier plate and driver. The extruded aluminum reflection back plate features high reflectivity and high thermal conductivity can promote light efficiency and dissipate heat fast, wherefore the present invention is exempted from burnout caused by high temperature.

Claims

1. A light-emitting-diode lamp bar, mounting a plurality of light emitting diodes (LED), and comprising:

an extruded aluminum reflection back plate being a strip-like structure and having an accommodation room;

at least one LED carrier plate arranged in said accommodation room and having a plurality of contacts respectively mounting said LEDs;

at least one driver coupled to said LED carrier plate and driving said LEDs to emit light;

a transparent lamp cover installed on said extruded aluminum reflection back plate and covering said accommodation room; and

two side plates installed on said extruded aluminum reflection back plate and cooperating with said transparent lamp cover to encase said accommodation room.

2. The light-emitting-diode lamp bar according to claim 1, wherein said side plate has an accommodation room accommodating said driver.

3. The light-emitting-diode lamp bar according to claim 2, wherein said side plate has a blocking cover used to close said accommodation room.

4. The light-emitting-diode lamp bar according to claim 1, wherein said contacts are arranged into a line or lines.

5. The light-emitting-diode lamp bar according to claim 1, wherein a power source is embedded on said extruded aluminum reflection back plate;

said power source is connected to said driver and supplies power to said driver.

6. The light-emitting-diode lamp bar according to claim 5, wherein a hood is arranged on one plane of said extruded aluminum reflection back plate, wherein said plane is far from said transparent lamp cover;

said hood accommodates said power source and said driver.
