Twin light integrated LED automobile headlamp

Abstract

The invention discloses a twin light integrated LED automobile headlamp and belongs to the technical field of automobile lamps. The twin light integrated LED automobile headlamp comprises a lens support, a lens, a reflecting cup and a light source assembly. The lens is installed on the reflecting cup through the lens support. The light source assembly is arranged in the reflecting cup. A low-beam reflecting hood and a high-beam reflecting hood are arranged in the reflecting cup and are opposite to each other. A cut-off line diaphragm is arranged at the front end of the low-beam reflecting hood. The light source assembly comprises a high-beam LED light source module and a low-beam LED light source module. The high-beam LED light source module faces the high-beam reflecting hood. The low-beam LED light source module faces the low-beam reflecting hood. According to the twin light integrated LED automobile headlamp, a low beam and a high beam are provided with the independent optical reflecting hoods respectively through the ingenious structure design; the cut-off line of the low beam can effectively protect the eyes of a driver of a car on the opposite side; the high beam is better condensed, the central luminance is high, and the irradiation distance is long; the optical axes of the high beam and the low beam can conduct illumination at the same time and coincide, and then a perfect light path light spot is formed.

Description

technical field [0001] The invention relates to an automobile headlight, more specifically, relates to a dual-light integrated LED automobile headlight. Background technique [0002] With the advancement of automobile technology, the production and sales of automobiles are constantly expanding, and the related accessories industry is also increasing. Automobile lamps are one of the main accessories. At present, the main accessories of automobile lamps are xenon lamps and halogen lamps. Xenon car lights and halogen car lights have high power consumption, short life, low brightness, and delay in starting. However, reducing energy consumption is the pursuit of all industries. The power consumption of on-board electrical appliances directly affects fuel consumption, especially for hybrid electric vehicles and pure electric vehicles. Energy saving is particularly important. Car lights consume the most energy in all electrical appliances in a car. Reducing the power consumption o...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the shortcomings of the existing automobile headlights, such as high energy consumption, low light efficiency utilization rate, and the inability to effectively combine the far and near light optical axes, and provide a dual-light integrated LED automobile headlight. The technical solution, through ingenious structural design, makes the high beam and the low beam have independent optical reflectors, the cut-off line of the low beam can effectively protect the eyes of the other driver, thereby reducing the accident rate, and the high beam is more concentrating. The central brightness is strong, and the irradiation distance is long. During high-speed driving, there will be no rear-end collision accidents due to astigmatism and dimness of the lights; The running light is integrated on the heat dissipation reflector cup of the LED car headlight, and uses the heat dissipation system of the LED car headlight to complete the heat dissipation of the daytime running light. The structure is compact, the heat dissipation is fast, and it has the characteristics of low energy consumption, high light efficiency utilization and long service life.
