Embodiment Construction

[0013] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0014] The most critical idea of ​​the present invention is: use the light guide plate of the daytime running light as the light-transmitting protective cover of the night running light, and combine the daytime running light and the night running light into one, which not only simplifies the structure but also has the functions of the daytime running light and the night running light, and can effectively Greatly save installation space and improve light utilization and anti-glare effect.

[0015] Specifically, please refer to figure 2 As shown, the composite automobile headlamp provided by the present invention includes a light guide plate 2, a reflector cup 4, a first LED light source 5 and a second LED light source 6, and the light guide plate 2 is arranged a...

Abstract

The invention relates to a composite automobile headlamp which comprises a light guide plate, a reflection cup, a first LED light source and a second LED light source; the light guide plate is arranged at the opening end of the reflection cup; the first LED light source is arranged on the side face of the light guide plate; and the second LED light source is arranged at the bottom of the reflection cup. Different from an existing automobile headlamp in which a daytime running light and a nighttime running light are arranged separately, the composite automobile headlamp uses the light guide plate of a daytime running light as a light-permeable protection cover of a nighttime running light to integrate the daytime running light and the nighttime running light, so that mounting space is effectively saved, the function of the daytime running light and the function of the nighttime running light are both achieved, the overall structure is concise and attractive, the light utilization ratio is high, and the anti-dazzle effect is good.

Description

technical field [0001] The invention relates to the technical field of vehicle lamps, in particular to a composite vehicle headlamp. Background technique [0002] At present, the daytime running lights and night running lights of vehicles on the market are separated and exist independently. The daytime running lights are usually installed around the night running lights and occupy a certain amount of space. [0003] The light-emitting mechanism of light-guiding daytime running lights mainly depends on the working principle of the light guide plate (such as figure 1 shown). The light source 1 enters light from the side of the light guide plate 2, and the light 3 enters the interior of the light guide plate 2. According to the law of total reflection, the light 3 is continuously reflected inside the light guide plate 2. When the light 3 is irradiated on the network point 20 (light guide point) on the lower surface of the light guide plate 2, the reflection condition will be ...
