Traffic tool lighting lamp with adjustable color temperature

Abstract

The invention relates to the technical field of the lighting tool, and discloses a traffic tool lighting lamp with adjustable color temperature. The lighting lamp comprises an lens, a lens mounting frame, a back shell, a circuit board, multiple light sources, a light guiding plate and a distant-light and near-light switching module; the lens is embedded at a front end part of the lens mounting frame, the lens mounting frame is fixedly connected with the back shell; multiple light sources are arranged at a front end surface of the circuit board in an matrix arrangement, multiple light guiding bodies are convexly arranged on the front end wall of the light guiding plate; the light sources are arranged at the backside of the light guiding bodies; the distant-light and near-light switching module comprises a light-blocking plate, and the light-blocking plate can be arranged in front of the light guiding plate in an upper-lower rotating manner; each light source comprises two LED beads withdifferent color temperatures; the color and brightness of the light source can be adjusted by adjusting the current of two LED beads; the light ray of the light source is converged to emit from the lens after being refracted through the light guiding bodies. Through the technical scheme disclosed by the invention, the brightness and color temperature of the light source can be adjusted as required, thereby effectively coping with the lighting demands under different climates, and effectively improving the driving security.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to a vehicle lighting fixture with adjustable color temperature. Background technique [0002] In the traditional vehicle lighting fixtures, the lighting fixtures are equipped with lamp beads and reflective cups. The reflective surface of the reflective cups is usually provided with electroplating. The electroplating layer has the function of concentrating light and can reduce the loss of light energy. The role of spot lighting. However, the heat of the light source will cause the reflector to be heated for a long time, which will easily increase the temperature inside the lamp, so that the electroplating layer of the reflector will turn yellow and fall off, resulting in the loss of the reflector. The function of spotlight affects the luminous effect and lifespan of LED lighting, and the current traditional traffic lighting has only a single light color, and the light col...
