The specific embodiment
Consult Fig. 1, Fig. 2 and Fig. 4; Fig. 1 is the decomposing schematic representation according to the led light source assembly of the utility model one embodiment; Fig. 2 is the assembling sketch map according to the led light source assembly of the utility model one embodiment, and Fig. 4 is the schematic rear view according to the led light source assembly of the utility model one embodiment.
As depicted in figs. 1 and 2, the led light source assembly of present embodiment comprises PCB wiring board 10 and a plurality of led light sources 20.Consult Fig. 4, a side of PCB wiring board 10 (downside of PCB wiring board 10 illustrated in figures 1 and 2) is provided with conducting wire layer 103, and is formed with a plurality of first openings 101 and a plurality of screws 102 on the PCB wiring board 10.
Each led light source 20 correspondence is arranged in one first opening 101, and is electrically connected with conducting wire layer 103.Further, the exiting surface of led light source 20 opposite side (upside of illustrated in figures 1 and 2 PCB wiring board 10) opposite that be positioned at PCB wiring board 10 with conducting wire layer 103.
Specifically, led light source 20 comprise support 21, be arranged at the top of support 21 and have exiting surface led chip 22, be arranged at two pins 23 and the heat-conducting plate 24 that is arranged at the bottom of support 21 of the relative both sides of support 21.When led light source 20 is installed on 10 last times of PCB wiring board, support 21 is arranged in first opening 101, and pin 23 is electrically connected with conducting wire layer 103 and led chip 22, and heat-conducting plate 24 is supported on the side that conducting wire layer 103 is set of PCB wiring board 20.
