Abstract
The utility model relates to a red-white LED (light-emitting diode) ceiling lamp of a cross-country vehicle. The ceiling lamp comprises a shell; the back surface of the shell is connected to the top of a vehicle driving room; the front surface of the shell is provided with a power supply switch, a left lens and a right lens; the shell is internally provided with a PCB (printed circuit board); a red light-emitting LED group and a white light-emitting LED group are welded on the PCB; the red light-emitting LED group is connected with a blackout lamp power supply wire; and the white light-emitting LED group is connected with an illuminating power supply wire. The red-white LED ceiling lamp provided by the utility model is simple in structure; the white light-emitting LED group is switched on under normal conditions to light up the internal space of the driving room; and the red light-emitting LED group is switched on under emergent conditions to play an air defense warning role. Additionally, as an LED is taken as a light source of the ceiling lamp, the ceiling lamp has the advantages of less heat, low power consumption, high brightness and long service life.
Description
Technical field
The utility model relates to the lighting device of offroad vehicle, refers to particularly the red white dichromatism LED ceiling light of a kind of offroad vehicle.
Background technology
At present, white top light only is equipped with at the automobile cab top, is used for the illumination cabin space.But offroad vehicle also needs to tackle various emergencies in order to realize outside general lighting, namely except the white illumination lamp as general lighting, also needs antiaircraft illuminating lamp.In addition, the ceiling light that is used for illumination adopts bulb as light source, and caloric value is large, and power consumption is high, and the life-span is short.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and provides a kind of offroad vehicle red white dichromatism LED ceiling light, and this ceiling light can be selected white illumination and red air defence warning as required, improves the performance of offroad vehicle.
