Embodiment Construction

[0012] Referring to the accompanying drawings, the structure and functions of the system will be described in detail below.

[0013] like figure 1 As shown, the LED car light is a line array or area array composed of a plurality of LED lamp beads 1 and an LED driving circuit board 2, and the LED lamp beads 1 and the LED driving circuit board 2 are electrically coupled;

[0014] The LED car light also includes a safety protection component 3, which is smaller in volume than the LED lamp bead 1, and is arranged close to the bottom of the LED lamp bead 1, and the safety protection component 3 includes an airbag 5 and a trigger 6;

[0015] like figure 2 As shown, the LED driving circuit board has a plurality of driving units 4, and each driving unit 4 includes a control module 7, a dimming module 8, a power supply module 9, two power supply sockets 10 and two signal sockets 11, and the power supply socket 10. Connect the dimming module 8, the power supply module 9 and the posit...

Abstract

The invention discloses an LED vehicle lamp of an electric vehicle. The LED vehicle lamp comprises LED lamp beads, an LED driving circuit board and safety protection modules. Each safety protection module comprises an air bag and a trigger. Each driving unit of the LED driving circuit board is provided with one LED lamp bead and one safety protection module correspondingly. Control modules of thedriving units receive adjusting signals from a user operation interface and also receive signals from vehicle collision sensors. In case of a vehicle collision, the LED lamp beads fall off from the LED driving circuit board, and the LED driving circuit board is protected by the air bags against damage. The LED vehicle lamp can be configured according to the actual demands or the demands of a client, various kinds of headlamp matrixes can be combined conveniently, a vehicle headlamp achieves the illumination function and also has a certain safety protection function, and the safety of the electric vehicle is improved. Moreover, the precise and expensive LED driving circuit board can be protected against damage, and the 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 ...
