Automobile lamp PES unit, automobile lamp assembly and automobile

Abstract

The invention relates to the technical field of an automobile lamp, in particular to an automobile lamp PES unit, an automobile lamp assembly comprising the automobile lamp PES unit and an automobilecomprising the automobile lamp assembly. The automobile lamp PES unit comprises a light source, a primary mirror, a first auxiliary mirror, a second auxiliary mirror and a lens. A light outlet is formed under the lens, and the light source is arranged at the perifocus of the primary mirror. The light emitted by the light source comprises main output light and residual light, the main output lightis reflected by the primary mirror and is projected onto the lens, and the residual light is not projected onto the lens. The first auxiliary mirror is arranged on the light path of the residual light, and the second auxiliary mirror is opposite to the first auxiliary mirror. The residual light is reflected by the first auxiliary mirror and the second auxiliary mirror successively and then is shotout from the light outlet. On the precise that the quantity of the light source and the power are not increased, the visual effect of multiple light sources is realized through a single light source,the lighting effect is improved, and the irradiation brightness and the effective irradiation distance are increased.

Description

technical field [0001] The invention relates to the technical field of automobile lamps, in particular to an automobile lamp PES unit, an automobile lamp assembly including the automobile lamp PES unit and an automobile including the automobile lamp assembly. Background technique [0002] At present, the PES unit of car lights has been widely used in the field of automotive lighting because of its small size, high energy utilization rate, uniform light pattern, and clear cut-off line. For example, the patent application with the publication number: CN105570794A discloses a PES unit with integrated LED far and near light for a car lamp and an ADB function, and specifically discloses a basic structure of the PES unit for a car lamp. [0003] The optical path design of the traditional headlight PES unit is as follows: figure 1 As shown, the LED light source 01 is set at the near focal point of the reflector 02, and the light emitted by the LED light source 01 is reflected by t...

AI Technical Summary

Problems solved by technology

[0004] Due to the design of the traditional car light PES unit with a single LED light source, the light emitted to form the illumination light pattern is all emitted from a lens 03, so the visual effect formed is that only a single light source emits light

Moreover, due to the small size requirement of the lens 03, only part of the light emitted by the LED light source 01 can be projected onto the lens 03 to form an effective output ( figure 1 The light shown by the solid line with the arrow in the center), there are also s
