Abstract

A light emitting diode (LED) traffic signal light module is provided. The LED traffic signal light module comprises a housing, an LED module, a power supply module and a lens set. The LED module is disposed on an inner wall in the housing. The power supply module is disposed in the housing, wherein the power supply module is electrically connected to the LED module. The lens set is disposed on the housing.

First claim

What is claimed is:

1. A light emitting diode (LED) traffic signal light module, comprising:
a housing, comprising a front panel;
an LED module disposed on an inner wall in the housing;
a power supply module disposed in the housing, wherein the power supply module is electrically connected to the LED module, wherein the power supply module is fixed to and arranged parallel to the LED module, the power supply module and the LED module are disposed on a mounting base disposed in the housing, and an entire bottom surface of the power supply module and an entire bottom surface of the LED module both directly contact the inner wall of the housing, wherein a material of the housing comprises a heat dissipation material; and
a lens set disposed on the front panel of the housing, wherein the front panel is movable for exposing the LED module and the power supply module inside the housing, such that the LED module and the power supply module inside the housing are repaired or replaced.

2. The LED traffic signal light module according to claim 1 , further comprising:
a connection wire module disposed in the housing, wherein the power supply module is electrically connected to an external power via the connection wire module.

3. The LED traffic signal light module according to claim 2 , wherein the power supply module is electrically connected to the connection wire module via a connector.

4. The LED traffic signal light module according to claim 1 , wherein the LED module comprises at least a high-power LED.

5. The LED traffic signal light module according to claim 4 , wherein the LED module further comprises at least an optical lens disposed on the high-power LED, and a light emitted from the high-power LED passes through the optical lens at a light emitting angle of 80-120 degrees.

6. The LED traffic signal light module according to claim 1 , wherein the front panel is movably disposed corresponding to a light emitting direction of the LED module.

7. The LED traffic signal light module according to claim 6 , wherein a light emitted from the LED module passes through the lens set and proceeds towards a predetermined direction.

8. The LED traffic signal light module according to claim 1 , wherein a material of the housing comprises a plastic material, a metal material, or a combination thereof.

9. The LED traffic signal light module according to claim 1 , wherein the lens set comprises an outer lens and an inner lens.
