Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to an LED light source board. Background Technology

[0002] The LED light source board is a crucial component in LED lighting products, containing electrical circuits and LED light-emitting particles. The most commonly used LED light source board on the market is made of aluminum substrate. The LED light source board is installed inside the lamp housing and is fixed to the housing with screws. During installation or when replacement is needed due to problems, tools are required to disassemble and reassemble the screws, making the process cumbersome, time-consuming, and labor-intensive. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide an LED light source board that can be magnetically installed, saving time and effort and is easy to operate.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An LED light source board includes an aluminum substrate, on which a plurality of LED patches are disposed, and a circuit connected to a power driver is laid on the aluminum substrate. A wire hole is opened in the middle of the aluminum substrate, and four rectangular pads are fixedly installed on the side of the aluminum substrate where no LED patches are disposed, and magnets are fixedly installed on the pads.

[0006] The aluminum substrate has notches on both sides, and a bracket is fixedly installed on the aluminum substrate opposite the notch. Two arc-shaped baffles are fixedly installed on the aluminum substrate, and the two ends of the arc-shaped baffles are fixedly connected to the two brackets respectively. A quick-release structure is installed on the bracket.

[0007] Thus, the main structure of the light source board includes an aluminum substrate, several LED chips mounted on the aluminum substrate, and circuitry for connecting the power driver laid on the aluminum substrate. This existing structure includes wiring holes for easy cable routing. The use of spacers and magnets facilitates the connection of the LED light source board to the iron ceiling light base via the magnets. During connection, the installation is completed by the magnets attracting the light source board to the iron ceiling light base. If the LED chips or circuitry are damaged and the light source board needs to be disassembled, the quick-release mechanism allows for easy separation of the light source board from the iron ceiling light base. The rounded edges and brackets facilitate the installation of the quick-release mechanism and allow better light transmission through the light-transmitting plate, improving the luminous effect.

[0008] Preferably, the quick-release structure includes two horizontal guide posts, the bracket has horizontal guide holes that slide with the horizontal guide posts, a handle is fixedly installed at the outer end of the horizontal guide posts, a shovel base is fixedly installed at the inner end of the horizontal guide posts, an upper inclined surface is provided at the end of the shovel base away from the bracket, two vertical guide posts are fixedly installed on the aluminum base, a slider has vertical guide holes that slide with the vertical guide posts, a lower inclined surface is provided at the end of the slider near the bracket, and the upper inclined surface and the lower inclined surface slide in contact.

[0009] Preferably, a tension spring is sleeved on the vertical guide post, the lower end of the tension spring is fixedly connected to the aluminum substrate, and the upper end of the tension spring is fixedly connected to the slider.

[0010] Preferably, the two sides of the handle are slidably fitted to the two sides of the bracket.

[0011] Preferably, a number of spaced-apart thermally conductive aluminum strips are fixed on the side of the aluminum substrate where no LED patches are provided.

[0012] In summary, this LED light source board has the advantages of magnetic installation, saving time and effort, and being easy to operate. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0017] like Figure 1-3As shown, an LED light source board includes an aluminum substrate 1, on which a plurality of LED patches 2 are provided, and a circuit connected to a power driver is laid on the aluminum substrate. A wire hole 3 is opened in the middle of the aluminum substrate. Four rectangular pads 4 are fixedly installed on the side of the aluminum substrate where no LED patches are provided, and magnets 5 are fixedly installed on the pads.

[0018] The aluminum substrate has notches on both sides, and a bracket 6 is fixedly installed on the aluminum substrate opposite the notches. Two arc-shaped baffles 7 are fixedly installed on the aluminum substrate, and the two ends of the arc-shaped baffles are fixedly connected to the two brackets respectively. A quick-release structure is installed on the bracket.

[0019] Thus, the main structure of the light source board includes an aluminum substrate, several LED chips mounted on the aluminum substrate, and circuitry for connecting the power driver laid on the aluminum substrate. This existing structure includes wiring holes for easy cable routing. The use of spacers and magnets facilitates the connection of the LED light source board to the iron ceiling light base via the magnets. During connection, the installation is completed by the magnets attracting the light source board to the iron ceiling light base. If the LED chips or circuitry are damaged and the light source board needs to be disassembled, the quick-release mechanism allows for easy separation of the light source board from the iron ceiling light base. The rounded edges and brackets facilitate the installation of the quick-release mechanism and allow better light transmission through the light-transmitting plate, improving the luminous effect.

[0020] In implementation, the quick-release structure includes two horizontal guide posts 8. The bracket has horizontal guide holes that slide with the horizontal guide posts. A handle 9 is fixedly installed on the outer end of the horizontal guide post. A shovel base 10 is fixedly installed on the inner end of the horizontal guide post. An upper inclined surface is provided at the end of the shovel base away from the bracket. Two vertical guide posts 11 are fixedly installed on the aluminum base. A slider 12 has vertical guide holes that slide with the vertical guide posts. A lower inclined surface is provided at the end of the slider near the bracket. The upper inclined surface and the lower inclined surface slide in contact.

[0021] In this way, when the outer side of the handle and the outer side of the aluminum substrate are on the same circumference, the slider is located below the curved edge, avoiding interference with installation. When disassembly is required, both hands simultaneously push the handle inward from both sides, causing the shovel base to move inward through the horizontal guide post. Utilizing the cooperation between the upper inclined surface and the lower inclined surface of the slider, the slider is pushed upward under the guidance of the vertical guide post. As the slider contacts the iron ceiling light base and continues to apply force, the aluminum substrate separates from the iron ceiling light base, and the magnet separates, achieving rapid disassembly. Compared to directly prying the sides of the aluminum substrate with fingers, the light source board can be removed much faster.

[0022] In practice, a tension spring 13 is fitted onto the vertical guide post. The lower end of the tension spring is fixedly connected to the aluminum substrate, and the upper end of the tension spring is fixedly connected to the slider. By using the tension spring, when there is no need to separate the light source board from the iron ceiling light chassis, the tension spring can hold the slider in place, keeping it below the arc-shaped edge and preventing interference with installation.

[0023] During implementation, the two sides of the handle slide against the two sides of the bracket, making the movement of the handle more stable and reliable.

[0024] In practice, a number of spaced-apart heat-conducting aluminum strips 14 are fixed to the side of the aluminum substrate without LED patches. The heat-conducting aluminum strips allow heat from the aluminum substrate to be quickly transferred to the iron ceiling light base, achieving heat transfer. Compared to heat transfer through the air without heat-conducting aluminum strips, the use of heat-conducting aluminum strips accelerates heat dissipation.

[0025] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
