Referring to fig. 10 to 14, the assembly process of the light source module 10 according to the present invention is described in detail as follows: firstly, the backlight side of the light source board 200 is close to the positioning side of the back plate 100, so that the pre-positioning holes 250 on the light source board 200 penetrate through the pre-positioning columns 140 on the back plate 100, thereby primarily mounting the light source board 200 on the back plate 100, and at this time, any two substrates 210 of the light source board 200 are separated by the electrical separation wall 190; then, the connecting side of the light distribution element 300 is close to the light emitting side of the light source board 200, the correction column 350 of the light distribution element 300 is made to pass through the automatic correction via 260 of the light source board 200, and a certain external force is applied at the same time, so that the first clamping claw 330 is in snap fit with the first clamping groove 150, the first clamping position 160 and the second clamping position 340 are clamped with each other, thereby mounting the light distribution element 300 on the backboard 100, at this time, the light source board 200 is fixedly mounted in the housing space formed by the backboard 100 and the light distribution element 300, the driving assembly 230 is located in the driving cavity 310, and the light emitting 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, so that the first end 421 is located at the predetermined position 3614, a certain external force is applied, the mounting buckle 3611 moves towards the outside of the mounting hole under the action of the external force, the first end 421 moves downwards to the mounting position 3613, and simultaneously, under the action of the elastic force of the mounting buckle 3611, the mounting buckle 3611 rebounds to the initial position and is buckled on the surface of the first end 421 away from the second end 422, so that the magnetic member is fixed to the mounting hole. When the pre-positioning hole 250 of the light source board 200 passes through the pre-positioning hole 140 of the back plate 100, the light source board 200 is initially positioned on the back plate 100, and the diameter of the pre-positioning hole 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 board 200 are not completely fixed and can generate a certain relative movement therebetween, and thus the position of the light source board 200 can be further adjusted and fixed in the process that the correction column 350 of the light distribution element 300 passes through the automatic correction via 260 of the light source board 200, so as to ensure that the position between the light source and the light distribution element 300 can meet the design requirement, and in this embodiment, the light distribution element 300 and the light source board 200 are placed in an offset manner to realize light distribution at different angles.

It will be understood by those skilled in the art that the mounting base of the present invention may be any object capable of fixing the light source module 10, and the fixing member 410 is used to fix the light source module 10 to the mounting base, in which case the mounting base may be a wall, a ceiling, or the like; since the mounting member 420 is a magnetic member, the mounting base generally has a magnetic characteristic, such as: the metal chassis 30 of the lamp, etc., and the present invention is not repeated. It should be noted that the fixing member 410 and the mounting member 420 can be used separately or in combination.

According to the utility model, the relative position precision of the light distribution element 300 and the light source can be greatly improved through two times of alignment by initially installing the pre-positioning column 140 and the pre-positioning hole 250 and then mutually matching the correction column 350 and the automatic correction via hole 260, so that the aim of accurate light distribution is achieved. The pre-positioning 3614 is arranged at the position of the mounting hole, so that the mounting piece 420 can be prevented from being normally mounted due to inclination in the mounting process or being damaged after being forcibly mounted, the mounting precision of the mounting piece 420 is improved, the design is ingenious, time and labor are saved, the improvement of the mounting efficiency of the light source module 10 on the mounting basis is facilitated, and the mounting device is suitable for large-scale popularization and application. The whole assembling process of the light source module 10 does not need to turn over all parts, all parts are assembled in a stacked buckling mode, the requirement on the professional degree of an operator is not high in the assembling mode, the automation degree is greatly enhanced, the production and manufacturing cost can be effectively reduced, and the production efficiency and the market competitiveness of products are further improved. Moreover, the light source board 200 is formed by splicing a plurality of the substrates 210, the light source module 10 with such a structure can independently distribute light for part of the light sources 220, and when the light sources 220 on a certain substrate 210 fail, the substrate 210 with the failed light sources 220 can be independently replaced, so that the independent local replacement of the light source board 200 can be realized, and the maintenance cost of the light source module 10 can be relatively reduced. The light source cavity 320 and the driving cavity 310 respectively cover the light source 220 and the driving assembly 230, so that the light source module 10 can improve the appearance, prevent the electrical crosstalk problem caused by too small a gap between the light source 220 and the driving assembly 230, and improve the protection performance.

In some embodiments of the utility model, after the light source module 10 is assembled, the light distribution lens 321 and the light sources 220 are disposed in an offset manner, in other words, at least one light source 220 is offset from the corresponding central position C of the light source cavity 320₁Preferably, at least one of the light sources 220 is disposed adjacent to the driving assembly 230, and at least one of the light sources 220 faces the central position C of the light source board 200₃Deviates from the corresponding central position C of the light source cavity 320₁Or at least one of the light sources 220 faces away from the center C of the light source board 200₃Deviates from the corresponding central position C of the light source cavity₁. It is understood that, as shown in fig. 14, the center position C of the light emission source 220 is satisfied₂And the central position C of the light source cavity₁It is not overlapped. Further, when the light source 220 is an LED light source and the light distribution lens 321 is a granular lens, each of the LED luminaries corresponds to one of the granular lenses, and at this time, at least the light distribution lens 321 near the driving cavity 310 and the light source 220 are disposed in an offset manner, the reason why the light distribution lens 321 and the light source 220 can be placed in an offset manner is that when the pre-positioning hole 250 of the light source board 200 passes through the pre-positioning column 140 of the back board 100, the pre-positioning hole 250 and the pre-positioning column 140 are in clearance fit, and a certain adjustment space is left, so that when the correction column 350 of the light distribution element 300 passes through the self-correcting via hole 260 of the light source board 200, the position for fixing the light source board 200 can be further adjusted to realize the offset distance required by the design between the light distribution element 300 and the light source board 200. The arrangement can change the light emitting path of the light emitting source 220 close to the driving chamber 310, and particularly, the light distribution lens 321 and the driving chamber 310 can be distributed and guidedThe path simulation analysis result is designed, and the deviation angle between the light distribution lens 321 and the light source 220 is adjusted, so that the purpose of avoiding the driving cavity 310 is achieved, and light rays are prevented from being reflected or refracted by the driving cavity 310 to the greatest extent to form bright spots or dark areas. Because the outer wall of drive chamber 310 is the arc setting, what the light shined to take place on the outer wall of drive chamber 310 is diffuse reflection, is difficult for producing the reflection or the refraction of a certain obvious specific angle, has further avoided forming bright spot or dark space.
