Problems solved by technology

These light patterns with special specifications must be achieved through the aforementioned optical design; moreover, due to the large light emitting angle of the light emitting diode, the probability of astigmatism is relatively high. The light output of the chip is clear, and the light-emitting diodes packaged by glue will cause light refraction due to the glue package when emitting light. At this time, it is easy to produce a situation that is difficult to control. A feasible response and solution must be proposed for the above situation.

Abstract

The invention discloses a vehicle headlamp having an anti-scattering structure. A main light assembly is arranged in a lamp housing, the main light assembly comprises a lamp cup, and a lamp plate and more than one scattering shielding plate, wherein the lamp cup has a front end and a rear end, an inwardly concave reflecting wall is formed on the front end, a through hole is formed in a bottom end of the reflecting wall, and passes through the rear end of the lamp cup, the lamp plate is arranged at the rear end of the lamp cup, more than one light emitting diode (LED) is arranged on the lamp plate, and faces the through hole in the lamp cup, the scattering shielding plate is located at a lower edge of the through hole, and shields part of light paths of the LED, thus generating a light type which can prevent the sight of an opposite vehicle from being affected and complies with regulations, and improving the problem of scattering.

Description

technical field [0001] The invention relates to a vehicle headlight, in particular to a vehicle headlight with an anti-scattering structure. Background technique [0002] At present, most automobile headlights still use high-intensity discharge lamps (HID) as light sources. Compared with halogen lamps, high-intensity discharge lamps with the same wattage can produce greater brightness. However, due to the development of semiconductor technology, light-emitting diodes that are more energy-saving and have a longer life have also begun to be used in automotive headlight lighting systems. Since headlight lighting requires higher brightness requirements, it is necessary to develop high-power light-emitting diodes and transmit them Secondary optical design is used to realize the application of light-emitting diodes in automobile headlights. The first optical design of the so-called secondary optical design is carried out during the packaging of light-emitting diodes to determine t...
