For N number of and inline, M ＞ N >=1；Front-seat LED chip formation low beam light source, front-seat LED chip and heel row LED chip is total to
With formation high-beam light source；The LED-baseplate front together with LED chip surface covered with fluorescent adhesive layer, the LED-baseplate
Front is provided with white adhesive layer in fluorescent adhesive layer, and the top surface of the LED chip is exiting surface.The utility model principle：In LED-baseplate
Whole front be all covered with white adhesive layer, the area of reflection is bigger, be conducive to improve LED/light source light extraction efficiency；When needs are beaten
When going out dipped beam light type, front-seat LED chip is lighted, "cut-off"line is cooperatively formed with light barrier；When needing to get distance light light type,
Front-seat LED chip and heel row LED chip are lighted simultaneously, and light barrier resets.As an improvement, the LED car lamp also includes and LED
Reflector that light source coordinates, it is arranged on and is used for the light barrier, lens and radiator that form "cut-off"line in front of LED/light source；Institute
LED/light source is stated to set on a heat sink.
As an improvement, heel row LED chip is altogether provided with two LED chips, front-seat LED chip is altogether provided with four LED cores
Piece.
As an improvement, the top surface and the either flush of LED chip of the white adhesive layer.
As an improvement, the reverse side of the LED-baseplate is provided with the input terminal pad of LED/light source, it is easy to laminating.
As an improvement, front-seat LED chip is overlapped with the Axisymmetric Distributed Line of heel row LED chip
The beneficial effect that the utility model is brought compared with prior art is：
LED chip of the present utility model is distributed using ladder so that have "cut-off"line during dipped beam for linear light sorurce；Far
Light time, the light collective effect of two row's LED chips, brightness is higher, meets the demand of distance light light type.
