Abstract

The invention discloses a light emitting diode (LED) automobile high beam, which comprises a reflecting cup. The high beam is characterized in that: the reflecting cup comprises a first parabolic surface, a second parabolic surface, a third parabolic surface and a fourth parabolic surface; the first parabolic surface is connected with the fourth parabolic surface; the first parabolic surface is totally symmetrical with the third parabolic surface, the second parabolic surface and the fourth parabolic surface are restrained by the same parabolic surface equation, and the area of the fourth parabolic surface is greater than that of the second parabolic surface; and the focal points of all the parabolic surfaces are superposed, an LED luminous source group is arranged at the focal points, and the LED luminous source group is fixed on an LED installation base. By adopting the automobile high beam, the emergent light spot is a rectangular light spot at the same time of ensuring that the emergent light is parallel light, and dizziness of the high beam and irradiation on human eyes are furthest reduced.

Description

technical field [0001] The invention is a lamp invention, in particular to an LED automotive headlight high beam lamp. Background technique [0002] With the improvement of living standards, automobiles have begun to become a popular consumer product and have entered millions of households, bringing huge business opportunities and attractive prospects to the automobile industry. As an important link in the automobile manufacturing industry chain, automobile accessories, especially the headlight system that is related to the safe operation of automobiles, will also bring a lot of market opportunities to related enterprises. The current automotive lamp market is mainly occupied by halogen lamps and xenon lamps. With its good development trend and its many advantages in recent years, LED has already had preliminary application and development in the automotive headlight market. At present, many brands in the automotive and other markets have launched their own LED lights and a...
