Further, described LED light source module comprise pcb layer, the LED chip be encapsulated on pcb layer, the reflector layer covering pcb layer surface and the wire be connected with pcb layer; Described LED installed surface is provided with mounting groove, and described LED light source module is embedded in described mounting groove.
Pcb layer, LED chip, reflector layer and wire all can select existing techniques in realizing.LED chip by pin package on pcb layer.Reflector layer is then for improving the brightness of LED light source module, and wire is used for LED light source module to be connected to power supply.The utility model arranges mounting groove especially on LED installed surface, and LED light source module embeds in mounting groove, and structure is simply convenient to assembling, is conducive to enhancing productivity.Meanwhile, mounting groove also helps the positions such as accommodation, shield wires joint and solder joint, avoids it exposed, is conducive to the outward appearance improving the utility model LED automobile lamp.
Further, also comprise the wire through-hole of through mounting groove, cooling base, described wire is arranged in wire through-hole.
Further, the middle part of described cooling base is provided with the installation projection of annular, and the edge installing projection is provided with installing hole.
Projection is installed be used for the utility model to be fixed in the reflector of auto lamp assembly, the screw that installing hole is then installed on fixing reflector.
Preferably, described pcb layer is provided with locating hole, is provided with the pilot pin penetrating locating hole in described mounting groove.
Automobile in the process of moving, easily jolts, shakes, and causes LED light source module to come off, damage.Therefore the utility model arranges locating hole especially on pcb layer, corresponding pilot pin is set in mounting groove simultaneously, pilot pin coordinates with locating hole, the stability of LED light source module in mounting groove can be strengthened, avoiding LED automobile lamp of the present utility model in use to damage because rocking, effectively improving reliability and the service life of product.
