Description

Technical Field

[0001] The utility model relates to the technical field of aluminum substrates, in particular to an aluminum substrate for LED lighting. Background Art

[0002] An aluminum substrate is a PCB, which also means a printed circuit board. The material of the circuit board is aluminum alloy. Previously, the material of our general circuit board was glass fiber. However, because LEDs generate a large amount of heat, the circuit boards used in LED lamps are generally aluminum substrates, which can conduct heat quickly. The circuit boards used in other devices or electrical appliances are still glass fiber boards. An aluminum substrate is a metal-based copper clad laminate with good heat dissipation function. Generally, a single-sided board consists of three layers, namely a circuit layer (copper foil), an insulating layer, and a metal base layer. It is commonly found in LED lighting products. It has two sides. The white side is for soldering the LED pins, and the other side shows the natural color of aluminum. Generally, a heat-conducting gel is applied and then it is in contact with the heat-conducting part.

[0003] During the use and installation process of the existing aluminum substrate, it is fixedly connected to the inner side of the installation cover through bolts. When installing the aluminum substrate, a large number of bolts need to be screwed in, the operation is not convenient enough, and the maintenance and replacement are also relatively troublesome. Moreover, most of the existing lamp covers are made of relatively soft materials such as plastics. The aluminum substrate is completely exposed inside the lamp cover. When the aluminum substrate is installed at a lower position, it may be damaged or even scrapped due to collision, causing greater losses. For this reason, we have proposed an aluminum substrate for LED lighting. Summary of the Utility Model

A stop block 23 and a buffer pad are fixedly connected to the upper surface of the mounting plate 1, and a through groove 24 is formed on the mounting plate 1.

[0028] Specifically, when using this aluminum substrate for LED lighting, fix one side of the mounting plate 1 to the inner side wall of the lamp cover, rotate the protective plate 5, the torsion spring 7 is stressed, one side of the protective plate 5 is fixedly connected to the sleeve 4, and the sleeve 4 is connected to the fixing rod 3 through the torsion spring 7, so that relative movement occurs between the sleeve 4 and the fixing rod 3, making an angle between the protective plate 5 and the mounting plate 1. Then place the aluminum substrate body 11 on the buffer pad on the mounting plate 1, slowly release the protective plate 5 to make the protective plate 5 reset, so that the lighting lamp on the aluminum substrate body 11 is located in the strip-shaped groove 6 on the protective plate 5. Screw the threaded rod 10 into the groove 9 on the protective plate 5, so that the threaded rod 10 enters the threaded tube 8, and the threaded rod 10 fixes the position between the protective plate 5 and the mounting plate 1. The end of the threaded rod 10 is designed as a countersunk head in the groove 9. The stop block 23 and the limiting component fix the aluminum substrate body 11 between the protective plate 5 and the mounting plate 1. When the aluminum substrate body 11 needs to be replaced, through the operation of the limiting component, the aluminum substrate body 11 can be drawn out from one side. The cooperation of the protective plate 5, the threaded tube 8 and the mounting plate 1 makes the aluminum substrate body 11 not easily damaged by collision, improving the safety when using this aluminum substrate for LED lighting.

[0029] The limiting component includes an arc-shaped rod 13 and two limiting blocks 14. Limiting grooves 16 are formed in both of the two mounting blocks 12.

The operation is convenient, without the need to screw in a large number of bolts, improving the work efficiency.
