In the accommodation space, the drive assembly 230 is located in the drive cavity 310, the light source 220 is located in the light source cavity 320; finally, the second end 422 of the magnetic member faces the first mounting hole 361, make the first end 421 at the predetermined position 3614, and then apply a certain external force, under the action of the external force, the installation buckle 3611 moves toward the outside of the installation hole, the first end 421 moves down to the installation position 3613, and at the same time, under the elastic force of the installation buckle 3611 itself, the installation buckle 3611 rebounds to the initial position, and buckles at the first end 421 away from the The surface of the second end portion 422 is fixed to the mounting hole. Wherein, when the pre-positioning holes 250 on the light source board 200 pass through the pre-positioning posts 140 on the backplane 100, the light source board 200 is preliminarily positioned on the backboard 100, and the pre-positioning posts The diameter of 140 is smaller than or equal to the aperture of the pre-positioning hole 250, so that the back plate 100 and the light source plate 200 are not completely fixed, and a certain relative movement can occur between the two, so that the light distribution element can In the process of the correction column 350 of 300 passing through the automatic correction via hole 260 of the light source board 200, the position of the light source board 200 can be further adjusted and fixed, so as to ensure the position between the light source and the light distribution element 300 Design requirements can be met, and in this embodiment, the light distribution element 300 and the light source plate 200 are offset to achieve light distribution at different angles.

Those skilled in the art can understand that the installation base in this application can be any object capable of fixing the light source module 10, and the fixing member 410 is used to install and fix the light source module 10 on the installation base, At this time, the installation base can be a wall, a ceiling, etc.; since the installation piece 420 is a magnetic piece, usually the installation base has the characteristics of magnetic adsorption at this time, such as: the metal chassis 30 of a lamp, etc., which are not included in this application. repeat. It should be noted that the fixing part 410 and the mounting part 420 can be used alone or in combination.

Furthermore, the light source board 200 is spliced by a plurality of the substrates 210, and the light source module 10 with this structure can separately distribute light for some of the light sources 220. When the light source 220 fails, the base plate 210 where the light source 220 fails can be replaced alone, and then the light source board 200 can be replaced individually and partially, which can relatively reduce the maintenance cost of the light source module 10 .
