The bottom of the light source cavity 13 integrally extends to form two sets of

fixing walls

131, 132 opposite to each other, the two sets of

fixing walls

131, 132 form a square frame, and the light source module 20 is fixed on the two sets of

fixing walls

131, 132.

Referring to fig. 3, in the present embodiment, the light source module 20 includes a metal heat dissipation plate 21 fixed on the

fixing walls

131 and 132, a circuit board 22 fixed on the heat dissipation plate 21, a cover plate 23 covering the periphery of the circuit board 22, and a first fixing member 24 and a second fixing member 25 for fixing the cover plate 23 on the heat dissipation plate.

The heat dissipating plate 21 is rectangular, and has fixing holes formed at both long sides thereof, and is fixed to the fixing wall 131 by screws so that both short sides thereof abut or are erected on the fixing wall 132. The inner side of the long side of the heat radiating plate 21 is protruded to form a fixing stand 211, and the fixing stand 211 extends from one short side to the other short side of the heat radiating plate 21. Sliding grooves 212 are formed on both side surfaces of the fixing base 211. The sliding groove 212 extends from a side surface of the fixed table 211 toward the other side surface, and has a small entrance and a large groove bottom, and the sliding groove 212 penetrates both ends of the side surface of the fixed table 211. The fixing base 211 is further formed with a screw hole extending rearward from the front of the fixing base 211 and a hole penetrating the heat radiating plate 21. It is understood that both the screw holes and the wire holes are sealed.

The circuit board 22 is fixed to the fixing table 211 by a fastener such as a screw, and has one surface (back surface) closely attached to the surface of the fixing table 211 and the other surface (front surface) provided with a plurality of light sources 221. In the present embodiment, the circuit board 22 is substantially (substantially or approximately, as determined by common knowledge) in a rectangular plate shape, and both the width and the length thereof are smaller than those of the fixing table 211. Conductive wires are also led out from both ends (near the short sides) of the circuit board 22, respectively, and extend from wire holes on the fixed table 211 to below the heat radiating plate 21.

The periphery of the cover plate 23 is rectangular, the width and the length of the cover plate are both greater than those of the circuit board 22, a concave part for accommodating the circuit board 22 is formed in the middle of the back surface of the cover plate, and optical lenses 231 are formed in positions of the concave part opposite to the plurality of light sources 221 of the circuit board 22 so as to perform preset optical processing on the light emitted by the light sources 221 and realize specific light effects. The cover plate 23 is preferably made of a chemically stable PC material. A groove or step 232 recessed from the top down (rearward from the front direction) is formed on the long side of the front surface of the cover plate 23. The groove or step 232 extends through both ends of the long side. The periphery of the back face of the cover plate 23 close to the cover plate should also form a groove for accommodating the sealing rubber ring, and the groove should be arranged outside the recessed portion, so as to ensure a good waterproof effect.

The first fixing member 24 is used for being connected with the fixing table 211 to press the cover plate 23 on the fixing table 211 in a manner that the long side of the cover plate is uniformly stressed. The second fixing member 25 is used for connecting with the fixing table 211 to press the cover plate 23 on the fixing table 211 in a manner that the short side of the cover plate is uniformly stressed. Therefore, the cover plate 23 is fixed to the heat radiating plate 21 in such a manner that the periphery thereof is uniformly forced.

The first fixing member 24 includes an elongated base plate 243 and two

slide rails

241, 242 extending substantially perpendicularly from two long sides of the base plate 243, wherein the slide rail 241 is inserted into the slide groove 212 on the side wall of the fixing platform 211 as a rear claw, and the other slide rail 242 is inserted into the groove or step 232 of the cover plate 23 as a front claw, and is pressed on the bottom of the groove or step 232 from top to bottom. By properly setting the width of the base plate 243, the first fixing member 24 can press the cover plate 23 onto the fixing table in a manner that the two long sides of the cover plate are uniformly stressed. It will be appreciated that the rear and front jaws 241,242 each have oppositely projecting portions for engaging with particular portions of the channel 212 and the recess or step 232.

The second fixing member 25 has a beam 251 and claw portions 252 extending downward from both ends of the beam 251, the claw portions 252 corresponding to the rear claws 241 are inserted into the slide grooves 212, and the beam 251 is used for pressing the short side of the cover plate 23 against the fixing base.

The utility model discloses a light source module is when the apron is compressed tightly on the fixed station by first and second mounting 24, 25, sets up the space between apron 23 below recess inboard sealed rubber ring apron and the fixed station to seal circuit board 22 in the space that apron 23 and fixed station 211 enclose, ensured circuit board and power module work in dry environment. Because the cover plate is fixed on the fixed platform in a way of uniformly stressing the periphery of the cover plate, the cover plate is not easy to crack even if becoming brittle due to being exposed to alkaline environment, and the service performance can be ensured.

In the above embodiment, the light source module is fixed in a state of being uniformly pressed on the periphery, it can be understood that in other embodiments, the second fixing member 25 may be omitted and only the first fixing member 24 may be used for the lighting fixture because the short side of the light source module is shorter.
