Description

Technical Field

[0001] This utility model relates to the field of LED aluminum substrate technology, specifically to an LED aluminum substrate. Background Technology

[0002] LED aluminum substrates are copper-clad laminates with excellent heat dissipation properties, primarily used in LED lighting products. They consist of a three-layer structure: a circuit layer (copper foil), an insulating layer, and a metal substrate. Common LED aluminum substrates include single-sided, double-sided, and multilayer boards, with single-sided boards being the most common. A single-sided board consists of a circuit layer, an insulating layer, and a metal substrate. Double-sided boards add an insulating layer and a circuit layer, while multilayer boards are made by bonding a standard multilayer board with an insulating layer and an aluminum substrate.

[0003] Chinese Patent Publication No. CN217495442U discloses an aluminum substrate for LED lamps, comprising an aluminum substrate body and a heat dissipation assembly mounted on the aluminum substrate body. The heat dissipation assembly includes a base plate fixed to the aluminum substrate body, a groove on the base plate containing coolant, a waterproof layer fixed to the groove to seal the coolant, multiple openings on the waterproof layer, and heat-conducting blocks fixed at the openings. The base plate also has multiple integrated bending portions extending to and in close contact with the surface of the aluminum substrate body. Multiple connecting portions are located on the side of the waterproof layer near the aluminum substrate body, and thermally conductive insulating mesh is provided at these connecting portions. This invention prevents the entire aluminum substrate from being damaged by excessive power during use, making it suitable for high-power LED lamp aluminum substrates.

[0004] Although the aforementioned aluminum substrate for LED lamps is not easily damaged by excessive power during use and is suitable for use in high-power LED lamps, aluminum substrates generally have poor dust resistance. When installing LED chips, dust easily accumulates on the surface of the aluminum substrate, especially at the connection between the LED chip and the aluminum substrate, which poses a certain risk of short circuit. Therefore, we propose an LED aluminum substrate. Utility Model Content

[0005] The purpose of this utility model is to provide an LED aluminum substrate to solve the problem mentioned in the background art that, due to the poor dust resistance of general aluminum substrates, dust easily accumulates on the surface of the aluminum substrate when installing LED chips, especially at the connection between the LED chip and the aluminum substrate, which poses a certain risk of short circuit.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an LED aluminum substrate, comprising:

[0007] Mounting plate, one end of which is mounted with an aluminum substrate, and both sides of the aluminum substrate are mounted with positioning bolts. One end of the aluminum substrate is connected to a lighting plate, and the lighting plate has several mounting slots inside.

[0008] LED beads are installed on the top of the inner wall of the mounting groove. A protective cover is installed inside the mounting groove, and a locking block is connected to one end of the protective cover. A magnetic strip is provided on the outer side of the mounting groove.

[0009] Heat dissipation holes are provided inside the aluminum substrate, and a number of heat dissipation fins are installed on one end face of the aluminum substrate.

[0010] Preferably, the aluminum substrate is connected to the mounting plate by positioning bolts, and the positioning bolts are symmetrically distributed about the vertical center line of the aluminum substrate.

[0011] Preferably, the mounting plate further comprises:

[0012] The limiting rotating plate is installed on both sides below the mounting plate. The limiting rotating plate is rotatably connected to the rotating shaft, and the limiting rotating plate is perpendicular to the positioning bolt.

[0013] Preferably, the LED beads correspond one-to-one with the mounting slots, and the protective cover engages with the mounting slots via locking blocks.

[0014] Preferably, the protective cover is magnetically attached to the lighting panel via a magnetic strip, and the protective cover corresponds one-to-one with the mounting groove.

[0015] Preferably, the heat dissipation holes are symmetrically distributed about the vertical center line of the aluminum substrate, and the heat dissipation fins are symmetrically distributed about the vertical center line of the aluminum substrate.

[0016] Compared with the prior art, the present invention provides an LED aluminum substrate, which has the following advantages:

[0017] The mounting slot of this utility model facilitates the installation of LED beads, and the protective cover can easily surround and protect the LED beads to prevent dust from entering. The lower end of the protective cover is made of metal and can be magnetically attached to the lighting board, making it easy to remove. This avoids the problem that ordinary aluminum substrates have poor dust resistance, and dust easily accumulates on the surface of the aluminum substrate when installing and using LED beads, especially at the connection between the LED beads and the aluminum substrate, which poses a certain risk of short circuit.

The limiting rotating plate 4 is rotatably connected to a rotating shaft, and the limiting rotating plate 4... The positioning bolt 3 is perpendicular to the positioning plate 3; the limiting plate 4 can rotate relative to the rotating shaft, so that the orientation of the limiting plate 4 can be easily adjusted. The positioning bolt 3 can be limited by the limiting plate 4 to prevent the positioning bolt 3 from loosening; one end of the aluminum substrate 2 is connected to the lighting plate 5, and the interior of the lighting plate 5 is provided with several mounting slots 8; the LED beads 9 correspond one-to-one with the mounting slots 8, and the protective cover 6 is engaged with the mounting slots 8 by the locking block 7; the mounting slots 8 facilitate the installation of LED beads 9, and the protective cover 6 can easily surround and protect the LED beads 9 to prevent dust from entering.
