AI Technical Summary
In the existing stage lamp module, the through holes at the bottom of the substrate need to be treated with C angle, resulting in increased processing costs; thermally conductive silicone grease may cause oxidation, rust or loosening of the screws; the gaps at the fastening screws will cause silicone grease to penetrate into the substrate chip and damage the chip; the thermal conductivity area of the substrate is reduced, affecting the heat dissipation efficiency; exposed screws are easily disassembled and leak design secrets; exposed fasteners affect aesthetics.
The module structure of hidden screws is adopted. By setting a positioning groove on the substrate and riveting or welding the fixing nut column, the bracket or shell is connected to the nut column through screws to achieve the fixing of the substrate and the bracket and shell, and the screw hole is closed through the glue plug to hide the screw.

Abstract
Description
Technical Field
[0001] The utility model relates to a stage light module, in particular to a module structure with hidden screws. Background Art
[0002] The common structure of stage light modules on the market is that screws penetrate holes from the bottom of the base plate to fix the housing and other hardware.
[0003] There are several disadvantages to this fixation:
[0004] 1. The through hole at the bottom of the PCB substrate needs to be processed with a C angle, and both the front and back sides need to be processed, which increases the processing cost of the substrate;
[0005] 2. When the module is in use, a large amount of thermal grease needs to be applied to the bottom of the substrate. In the case of long-term use, if there are chloride ions, oxidants or acidic substances in some thermal grease, it may cause the screws to oxidize, rust or even loosen;
[0006] 3. The fastening screws at the bottom of the PCB substrate should also be coated with thermal grease in the case of production aging. Since there is a C angle at the fastening screws, the screws are not completely sealed. One is that the thermal grease penetrates into the front of the substrate chip from the gap between the screws and the substrate, and the volatile silicone oil damages the chip; the other is that a small amount of silicone grease will penetrate into the gap between the screws and the C angle, and the cleaning before shipment is time-consuming and laborious;
[0007] 4. There are countersunk screw fasteners in many places on the bottom substrate, which reduces the actual heat conduction area of the copper substrate and affects the heat dissipation efficiency;
[0008] 5. The exposed screws at the bottom of the substrate are easily disassembled by competitors and customers, leaking the company's design secrets;
[0009] 6. The exposed fasteners at the bottom of the baseboard affect the appearance. Utility Model Content
[0010] The technical problem to be solved by the utility model is to provide a module structure with hidden screws to solve the problems existing in the background technology.
[0011] The module structure of the hidden screw of the utility model is realized by the following technical solutions, including:
[0012] A substrate, on which an LED lamp module is arranged;
[0013] An array lens assembly, wherein the array lens assembly is connected to the substrate via a fastener locking structure;
[0014] The shell component is connected to the base plate through a fastener locking structure, and the fastener locking structure is shielded by a rubber plug, and the array lens component is placed inside the shell component.
[0015] As a preferred technical solution, the array lens assembly includes a homogenizer, a bracket, a lens body and a convex lens mounting seat;
[0016] The homogenizing mirrors are installed above and below the bracket respectively, and the homogenizing mirror located below corresponds to the position of the lens body;
[0017] The convex lens mounting seat is arranged on the LED lamp module of the substrate, and the small convex lens body on the convex lens mounting seat corresponds to the position of the LED lamp module chip; the bracket is fixed to the substrate by a fastener locking structure.
[0018] As a preferred technical solution, the housing assembly includes a shell, a large convex lens body and a pressure ring;
[0019] The shell component body is fixed on the shell through a pressure ring, and the position of the shell component body corresponds to that of the array lens component; the shell and the substrate are fixed to the substrate through a fastener locking structure.
[0020] As a preferred technical solution, the fastener locking structure includes a screw hole provided on the bracket or the housing and a positioning groove provided on the base plate;
[0021] The positioning groove is fixed with a nut column by riveting or welding, and the bracket or shell is connected to the nut column by a screw set in the screw hole, thereby achieving fixation of the substrate to the bracket and the shell; a rubber plug is set above the screw hole of the shell, and the screw hole of the shell is closed by the rubber plug.
[0022] As a preferred technical solution, a rubber pad is provided between the shell and the base.
[0023] The beneficial effects of the utility model are:
[0024] 1. The utility model adopts nut columns fixed by riveting or welding, so that there are no screw holes on the back of the substrate, which effectively avoids the problem of silicone grease infiltration that may be caused by the screw holes and improves the air tightness of the product;
[0025] 2. The setting of the hidden screws of the utility model makes the entire module structure more concise and elegant in appearance, without exposed screws, thus enhancing the aesthetics of the product;
[0026] 3. In the present invention, since the screws are hidden under the rubber plug, destructive disassembly is required to access the screws, which effectively prevents the risk of illegal disassembly and leakage;
[0027] 4. The utility model helps to improve the heat dissipation efficiency by increasing the heat dissipation contact surface of the substrate, thereby ensuring that the LED lamp module can work stably in a high temperature environment. BRIEF DESCRIPTION OF THE DRAWINGS
