Moreover, there is a lamp holder 12 between the two heat dissipation parts 11, the lamp holder 12 has a joint surface 121, the joint surface 121 is inclined from the center to both sides, and a convex part 122 protrudes from the periphery of the lamp holder 12, and is connected to the body. 1 A plurality of fixing holes 123 are respectively provided on the opposite sides of the adjacent lamp holder 12 (three screw holes are taken as an example in the figure), whereby the lamp holder 12 is provided with a lamp 2 and at least one spotlight frame 3 in sequence, Then cover the light-transmitting plate 4 and the fixing frame 5 .

In addition, a plurality of heat conduction holes 124 are respectively pierced on the two end surfaces of the heat dissipation portion 11 of the main body 1 to provide two heat conduction rod groups 13 .

The thermal conductivity of each heat conducting rod group 13 is higher than that of the main body 1 . In the present invention, the above-mentioned main body 1 can be made of aluminum, and the two heat conducting rod groups 13 can be made of copper. The two heat-conducting rod groups 13 respectively use a main rod 131 to vertically connect several secondary rods 132, and each secondary rod 132 is respectively inserted into the heat-conducting holes 124 of the heat dissipation parts 12 on both sides, and extends into the lamp holder 12 of the main body 1. And adjacently arranged (see Fig. 5 and Fig. 6 sectional views for details), so that the heat conduction rod group 13 can transfer heat quickly, and at the same time, each main rod 131 is fixed on the body 1, which is fixed by screw locking, and To position the secondary rod 132 inserted in the main body 1, the heat generated by the lamp 2 is quickly transferred to the main body 1 through the heat conduction rod group 13 with high thermal conductivity, and the heat dissipation part 11 on the main body 1 is used to communicate with the outside world. heat exchange.

The lamp 2 is composed of at least one LED module 21 (take twelve groups of LED modules as an example in the figure), and each LED module 21 is controlled by a circuit board 22 at the same time. The face 23 (opposite to the face providing the light source) abuts against the joining face 121 of the body 1 .

In addition, a heat conduction material (not shown) can be disposed between the joint surface 121 of the main body 1 and the heat dissipation surface 23 of the lamp 2, and the heat conduction material can be coated with heat dissipation paste for effective heat conduction.

In the foregoing, twelve light-concentrating frames 3 are used here as an example, which are positioned in the lamp socket 12 of the main body 1 to match the light sources of the LED modules 21 of the lamp 2 .
