Wherein, LED light source further comprises the heat-conducting plate of the bottom that is arranged at support, and heat-conducting plate is supported in a side of PCB wiring board.
Wherein, pin is fixed on the layer of conducting wire and with conducting wire layer and is realized and being electrically connected by welding manner.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of LED light fixture is provided, and this LED light fixture comprises above-mentioned LED light source assembly.
Wherein, LED light fixture further comprises radiator.On the upper surface of PCB wiring board and radiator, be respectively arranged with screw, PCB wiring board by screw and screw be fixed on radiator and a side of PCB wiring board towards radiator.
Wherein, LED light fixture further comprises a lens holder plate and multiple lens unit, lens holder plate is fixed on radiator and is provided with second opening corresponding with LED light source, each lens unit respectively correspondence is arranged in one second opening, and PCB wiring board and LED light source are arranged between lens holder plate and radiator.
The invention has the beneficial effects as follows: the situation that is different from prior art, the present invention accommodates LED light source by the first opening, can improve the fixed effect of LED light source and reduce setting height(from bottom), and further by making the exiting surface of LED light source be positioned at the opposite side contrary with conducting wire layer of PCB wiring board, can make the outward appearance of LED light source assembly and LED light fixture more succinct, attractive in appearance.And LED light source directly contacts with radiator, has reduced the direct thermal resistance of LED light source and radiator, has improved the radiating effect of LED light source.

Detailed description of the invention
Consult Fig. 1, Fig. 2 and Fig. 4, Fig. 1 is the decomposing schematic representation of LED light source assembly according to an embodiment of the invention, Fig. 2 is the assembling schematic diagram of LED light source assembly according to an embodiment of the invention, and Fig. 4 is the schematic rear view of LED light source assembly according to an embodiment of the invention.
As depicted in figs. 1 and 2, the LED light source assembly of the present embodiment comprises PCB wiring board 10 and multiple LED light source 20.Consult Fig. 4, in a side (downside of the PCB wiring board 10 shown in Fig. 1 and Fig. 2) of PCB wiring board 10, be provided with conducting wire layer 103, and on PCB wiring board 10, be formed with multiple the first openings 101 and multiple screw 102.
Each LED light source 20 correspondences are arranged in one first opening 101, and are electrically connected with conducting wire layer 103.Further, the exiting surface of LED light source 20 is positioned at the opposite side contrary with conducting wire layer 103 (upside of the PCB wiring board 10 shown in Fig. 1 and Fig. 2) of PCB wiring board 10.
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 support 21 relative both sides two pins 23 and be arranged at the heat-conducting plate 24 of the bottom of support 21.In the time that LED light source 20 is installed on PCB wiring board 10, support 21 is arranged in the 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 in the side that conducting wire layer 103 is set of PCB wiring board 20.
In the present embodiment, the shape of support 21 is identical with the shape of the first opening 101, and is specifically decussate texture.By the way, can carry out effective location to LED light source 20, improve the fixed effect of LED light source 20.Pin 23 is fixed on conducting wire layer 103 and with conducting wire layer 103 and is realized and being electrically connected by welding manner.Certainly, in other embodiments, the shape of support 21 and the first opening 101 can be set arbitrarily as required, and pin 23 can be realized by other means fixing and be electrically connected with conducting wire layer 103, for example, pass through conducting resinl.
Further, in the present embodiment, PCB wiring board 10 is circular configuration, and two pins 23 of each LED light source 20 are positioned at the same radial direction of PCB wiring board 10, so that multiple LED light sources 20 are radially distributed from PCB wiring board 10 centers.
