Abstract

The invention discloses an LED matrix headlamp of an electromobile. The LED matrix headlamp of the electromobile comprises a plurality of LED lamp beads and an LED drive circuit board, and further comprises safety protection assemblies which are made into sizes same with those of the LED lamp beads. Each safety protection assembly comprises an air bag and a trigger, wherein the trigger is providedwith two second power receiving pins which can be inserted into power supply sockets and a second signal receiving pin which can be inserted into one of two signal interfaces. Each drive unit of theLED drive circuit board is correspondingly provided with one LED lamp bead or one safety protection assembly. When the drive units are provided with the LED lamp beads, a control module is configuredinto a lighting control manner; and when the drive units are provided with the safety protection assemblies, the control module is configured into a safety control manner. By means of the LED matrix headlamp of the electromobile, multiple headlamp matrixes can be conveniently combined according to actual demands or client configuration, so that a certain safety protection function is achieved while the automobile headlamp achieves the lighting function, and the safety of an electromobile is improved.

Description

technical field [0001] The invention belongs to the fields of electric vehicles, LED lighting and automobile safety, and in particular relates to an electric vehicle LED matrix headlight and a safety protection component thereon. Background technique [0002] Due to the advantages of small size, low power consumption, high brightness, and environmental protection, LED has become an ideal light source to replace traditional light sources. The application of LED light sources is very flexible, and can be made into various forms of point, line, and surface matrices, and the control is also very convenient. , the light intensity and / or light color of the LED can be freely controlled only by controlling the current. LEDs have been widely used in the field of automotive lighting, such as vehicle headlights. However, a single type of LED headlight cannot meet the diverse safety requirements of vehicles. For example, LED headlights do not have certain collision protection functions....
