Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] The inner surface of the high-beam reflector provided by the embodiment of the present invention is formed by rotating a spline curve. The light emitted by the light source is emitted directly or only reflected once by the inner surface of the reflector, that is, parallel emission. The requirements of light distribution performance, and the light decay is small.

[0016] The inner surface of the high beam reflector provided by the embodiment of the present invention is formed by rotating a spline curve, and the central axis of the reflector coincides with the optical axis of the light source...

Abstract

The invention is applicable in the field of illumination, and provides a high beam lamp reflector, a high beam lamp and a motor vehicle. The inner surface of the reflector is formed by curved rotation of splines, and the central axis of the reflector is superposed with the optical axis of a light source. The inner surface of the high beam lamp reflector provided by the embodiment of the invention is formed by curved rotation of the splines, most of light emitted by the light source is directly emergent, and only a small part of the light is reflected once through the inner surface of the reflector and then emergent in parallel to form long-distance projection, so the light is centralized and meets the requirement of light distribution performance of the high beam lamp, and the light attenuation is low.

Description

technical field [0001] The invention belongs to the field of lighting, and in particular relates to a high beam reflector, a high beam and a motor vehicle. Background technique [0002] At present, the light sources of automobile headlights are mainly halogen tungsten lamps and high-pressure gas discharge lamps. The lamps have poor shock resistance, short service life, and relatively high power consumption. In contrast, LED light sources have the advantages of energy saving, long life, and good shock resistance. The development of LED as a light source for automobile headlights has been a hot spot in recent years. [0003] After 2004, various LED headlights were exhibited at international auto exhibitions. In May 2007, Japan's Koito Manufacturing Co., Ltd. successfully installed white LED headlights on the LEXUS LS600h model. The optical system uses The ellipsoidal reflector and lens form a transmissive optical system. In 2007, OSRAM Germany launched the LED module "OSTAR...
