Embodiment Construction

[0018] As shown in the figure for the LED car high beam lamp structure, the reflector 2 includes a first parabola 4, a second parabola 5, a third parabola 4, and a fourth parabola 5 that are connected in sequence; the first parabola 4 also Connected to the fourth parabolic surface 5; the first parabolic surface 4 and the third parabolic surface 4 are completely symmetrical, the second parabolic surface 5 and the fourth parabolic surface 5 are constrained by the same parabolic surface equation, and the area of ​​the fourth parabolic surface 5 is larger than the first The area of ​​the two parabolic surfaces 5; the focal points of all parabolic surfaces coincide. The LED light-emitting source group 1 is set at the focal point, and the LED light-emitting source group is fixed on the LED mounting base 6, and the outside of the LED mounting base 6 is provided with a claw-shaped heat dissipation shell 3. According to the requirements of the shape of the light spot, the distance of th...

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