Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] refer to figure 1 , the present invention includes a lampshade 1, a housing 2, a lamp cap 10 equipped with a light-emitting diode, and a power connection 3. The lampshade 1 is provided with a heat sink support 4, and a lamp board 5 is fixed on the heat sink support 4, and the heat sink support 4 There is also a graphite heat sink on the top. The heat sink support 4 divides the internal space formed by the lampshade 1 and the shell 2 into three cavities. The graphite heat sink is arranged in the upper cavity and fixed on the heat sink support 4. The chamber 9 is filled with heat dissipation material, and the lower cavity is the lens installation chamber 6 .

[0017] The thermistor 8 is also arranged on the power connection 3, and its resistance value increases with the increase of the temperature in the lamp, which can better prevent potential safety hazards caused ...

Abstract

An LED explosion-proof vehicle lamp comprises a lampshade, a shell, a lamp holder and a power connection line. The lamp holder is provided with light emitting diodes, a radiating fin support is arranged in the lampshade, a lamp panel is fixed onto the radiating fin support, and graphite radiating fins are arranged on the radiating fin support. The LED explosion-proof vehicle lamp is simple and compact in structure, fine in radiating performance, not easy to cause light attenuation, long in serve life and wide in application range.

Description

technical field [0001] The invention relates to an LED explosion-proof vehicle lamp. Background technique [0002] LED car light is a car light that uses LED (light-emitting diode) as the light source, because LED has the characteristics of high brightness, rich colors, low power consumption and long life, and the light source can directly produce the red color required by car lamps without color filtering , amber and other colors, no loss, and the power utilization rate is as high as 80%, so it is widely used in the automotive field. However, the functions of the existing LED car lights are not comprehensive enough, the design concept is not humanized enough, the waterproof, dustproof and explosion-proof performance is poor, the heat dissipation performance is not good, and light decay is prone to occur, which often leads to excessively high internal temperature of the car lights, thus affecting the quality of the car. lamp life.
