Abstract

The invention discloses an LED car high beam. The LED car high beam comprises a plurality of LED light sources, a plurality of free-form surface optical lenses, a lens support and a base plate. The lens support and the LED light sources are fixed to the base plate, and a plurality of holes for emergent light of the LED light sources to pass through are correspondingly formed in the lens support. One free-form surface optical lens is arranged at each hole in the lens support, and the distance between light-emitting faces of the LED light sources and incident planes of the free-form surface optical lenses is fixed according to the height of the lens support. The LED car high beam is simple in structure, high in light energy utilization efficiency, simple and stable in structure, convenient to assemble, low in cost, long in service life, good in light distribution performance and capable of meeting GB25991-2010 light distribution requirements. According to the LED car high beam, exit planes of the lenses are free-form surfaces, so that the appearance of the whole car high beam can be more flexible and meet requirements for beautification and streamline of modern car high beam design.

Description

technical field [0001] The invention relates to the technical field of LED automobile lamp lighting, in particular to a free-form surface optical lens used for LED automobile high beam lamps. Background technique [0002] In recent years, with the continuous advancement of light-emitting diode (LED) technology and the popularization of applications, the application of LEDs in automotive lighting has become more and more common. The light sources of traditional automobile headlights have disadvantages such as low efficiency, short lifespan, and non-environmental protection, while LED light sources have many advantages such as energy saving, high efficiency, and environmental protection. Using LED light sources to replace traditional light sources will be a development trend for automotive headlights. In recent years, with the continuous advancement of LED technology and the popularization of applications, the application of LEDs in automotive lighting has become more and more...
