Abstract

The invention discloses an LED car lamp. The LED car lamp comprises LED beads, an LED driving circuit board, supports and safety protection assemblies; and the safety protection assembly comprises anair bag and a trigger, each driving unit of the LED driving circuit board is correspondingly provided with one support, one LED bead and one safety protection assembly, and a control module of each driving unit receives an adjusting signal coming from an user operation interface and meanwhile receiving signals coming from a vehicle collision sensor; during car collision, the LED beads fall from the LED driving circuit board, and the LED driving circuit board is protected by the air bag to prevent damage. By means of the LED car lamp, a plurality of headlamp matrixes can be combined conveniently according to actual needs or client allocation, car headlamps have a certain safety protection function while the lighting function is achieved, the safety of electric cars is improved, the precision and expensive LED driving circuit board can be protected and can be prevented from being damaged during car collision, and cost is saved.

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 lamp 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. Contents ...
