Abstract

The invention provides an LED (Light-Emitting Diode) traffic signal lamp device, which comprises a first LED signal lamp, a second LED signal lamp and a third LED signal lamp, wherein the first LED signal lamp, the second LED signal lamp and the third LED signal lamp respectively display three kinds of color to express three traffic states. The LED traffic signal lamp device also comprises a first light-sensitive unit packaged in the first LED signal lamp, a second light-sensitive unit packaged in the second LED signal lamp, and a third light-sensitive unit packaged in the third LED signal lamp, and the first light-sensitive unit, the second light-sensitive unit and the third light-sensitive unit are respectively used for periodically sensing the light-emitting states of the first LED signal lamp, the second LED signal lamp and the third LED signal lamp. A control unit judges when the first LED signal lamp, the second LED signal lamp and the third LED signal lamp normally work or not according to signals received from the first light-sensitive unit, the second light-sensitive unit and the third light-sensitive unit, and light-emitting control signals sent to the first light-sensitive unit, the second light-sensitive unit and the third light-sensitive unit.

Description

Technical field [0001] The present invention relates to the field of LED technology, and more specifically, the present invention relates to an LED traffic signal lamp device. Background technique [0002] LED (Light Emitting Diode) is a new type of light source developed and produced in recent years. It has low power consumption (current only 10-20mA), high brightness (light intensity can reach tens of thousands of mcd), and small size (the smallest diameter can reach 3mm) , Light weight (a light-emitting diode weighs only a few ten grams), long life (average life of 100,000 hours) and other advantages. It has gradually replaced incandescent lamps and low-voltage tungsten halogen lamps to make road traffic signal lights. [0003] LED traffic lights are light and color signals that are alternately replaced at a specified time. They are usually installed at intersections or other special places to assign roadway rights to vehicle drivers and pedestrians, and to control traffic cont...
