Automobile LED (Light Emitting Diode) headlamp

Abstract

The invention discloses an automobile LED (Light Emitting Diode) headlamp. The automobile LED headlamp is characterized in that a light source fixing frame comprises an installing end and a fixing end, wherein the installing end has three installing surfaces, three aluminum substrates are respectively arranged on the three installing surfaces, two of the aluminum substrates are arranged far away from the fixing end, one of the aluminum substrates is arranged close to the fixing end, and the aluminum substrates are provided with LED light sources; a radiator comprises a connecting end and a heat dissipation end, an installing hole is formed in the connecting end, a containing groove is formed in the heat dissipation end, the fixing end is connected with the installing hole in an interference fit way, a heat dissipation fan is contained in the containing groove, and a dust cover is attached to the heat dissipation end; a fixing piece is connected to the fixing end in a sleeving way, and a protecting cover is connected with the end surface of the installing end. According to the automobile LED headlamp disclosed by the invention, the automobile LED headlamp is arranged in a limited space range, on one hand, due to 360-degree light emitting of the LED light sources, the utilization rate of the LED light sources is increased, and on the other hand, due to reasonable structure design of all components, the heat dissipation problem of the LED light sources is well solved, and the service life of the LED light sources is prolonged.

Description

technical field [0001] The invention relates to a lamp, in particular to an automobile LED headlamp. Background technique [0002] There are two main types of traditional car headlights, one is halogen bulbs with standard interfaces such as H1, H4, H7, and H11 commonly used in the industry, and the other is gas discharge lamps, such as xenon headlights. The filament of the halogen headlamp is fragile, has a short lifespan, and is easy to burn out when switched on and off frequently. The start-up voltage and current of the xenon headlamp are high, the driving circuit has a wide working range, great difficulty and high failure rate. [0003] LED headlights have energy saving, long life, green environmental protection, no flicker, impact resistance, work under low thermal voltage, wide voltage range, high luminous efficiency, high brightness, fast response, high CRI, good color reproduction, weather resistance The advantages of high reliability and good reliability make it gr...
