Description

Technical Field

[0001] The utility model relates to the technical field of COB light sources, in particular to a COB light source packaging structure. Background Art

[0002] COB technology is an innovative achievement in modern lighting technology. It installs LED chips directly on a substrate. The high thermal conductivity of the substrate material allows heat to be quickly transferred away from the chip, thereby effectively solving the heat dissipation problem.

[0003] When the existing COB light source package is actually used, the light source sheet is usually fixed by bonding. If the bonding is not tight, the light source sheet will become loose and fall off. If the bonding is tight, it will be difficult to remove the light source sheet later, resulting in the light source sheet being easily broken after disassembly, which is very inconvenient during installation and disassembly. Therefore, it is necessary to provide a packaging structure that can avoid the above-mentioned falling off or breaking to ensure the convenience of installation and disassembly of the light source sheet. Summary of the invention

[0004] The purpose of the present utility model is to provide a COB light source packaging structure to solve the problem raised in the above-mentioned background technology. In actual use, the existing COB light source packaging usually adopts a bonding method to fix the light source sheet. If the bonding is not tight, the light source sheet will become loose and fall off. If the bonding is tight, it will be difficult to remove the light source sheet at a later time, resulting in the light source sheet being easily broken after disassembly, which is very inconvenient during installation and disassembly.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a COB light source packaging structure, comprising:

[0007] A body component, the body component comprising a substrate and a light source sheet;

[0008] A fixing component, the fixing component comprising a guide rod, a guide ring, a limit plate, a support rod, a clamping ring, an internal threaded ring, a threaded rod and a handle;

[0009] The guide rod is symmetrically connected to the top of the base plate, the guide ring is symmetrically and movably connected to the outer surface of the guide rod, the middle of one side of the guide ring is connected to the support rod, one side of the support rod is connected to the clamping ring, and both ends of the guide rod are fixed with limit plates.

[0010] Furthermore, the clamping ring is clamped on the outside of the light source sheet, and the clamping ring is in an arc shape.

[0011] Furthermore, the middle part of the other side of the guide ring is connected to an internal threaded ring, the middle part of the internal threaded ring is connected to a threaded rod, and the outer end of the threaded rod is rotatably connected to a handle.

[0012] Furthermore, the body component also includes a mounting plate and an inner groove;

[0013] An inner groove is provided in the middle of the top of the base plate, the light source sheet is located inside the inner groove, and both sides of the outer wall of the base plate are fixedly connected to the mounting plate.

[0014] Furthermore, it also includes a supporting component, which includes a supporting plate, a slide rail, a limit block, a slider, a positioning block and a rubber column;

[0015] The support plate is connected to the inside of the inner groove, the bottom circumference of the base plate is equidistantly connected to the slide rail, the outer surface circumference of the support plate is equidistantly connected to the slider, the slider is movably connected to the inside of the slide rail, and the two sides of the outer wall of the slider are connected to positioning blocks.

[0016] Furthermore, both sides of the outer wall of the slide rail are connected to limit blocks, the limit blocks are symmetrically clamped at both ends of the positioning block, the inner wall of the limit block is bonded to a rubber column, and the rubber column blocks the bottom of the positioning block.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] The utility model is provided with a guide rod, and a guide ring is provided on the outside of the guide rod, and a clamping ring is provided on the outside of the guide ring. The light source piece can be placed inside the inner groove, and the guide ring is moved on the outside of the guide rod. According to the position of the light source piece, the clamping ring is completely clamped on the outside of the light source piece, and the light source piece is clamped and fixed by the clamping ring. The threaded rod is rotated so that the threaded rod is clamped and fixed on the outside of the guide rod. When disassembling, the threaded rod is loosened so that the guide ring is adjusted on the outside of the guide rod, and the clamping ring is separated from the light source piece. The light source piece can be disassembled, thereby avoiding the phenomenon of loosening or breaking of the light source piece after installation, and ensuring the convenience of installing and disassembling the light source piece.

[0019] Based on the above beneficial effects, a slide rail is provided at the bottom of the substrate and a slider is provided on the outside of the support plate, so that the support plate will be supported on the bottom of the light source sheet. After long-term use, the traditional support plate is fixedly installed inside the substrate, and some dust particles will be generated on the surface of the support plate. It is difficult to clean the dust particles attached to the surface. By sliding the slider inside the slide rail, the support plate is pulled downward to separate the positioning block from the limit block. The support plate can be removed separately for cleaning, which saves time and effort and is very convenient to clean. BRIEF DESCRIPTION OF THE DRAWINGS
