Description

Technical Field

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

[0002] In recent years, LED (light-emitting diode) technology has gradually replaced traditional incandescent and fluorescent lamps, becoming the mainstream technology in the lighting field, thanks to its advantages such as high energy efficiency, long lifespan, and environmental friendliness. However, with the widespread application of LEDs, the maintenance and replacement issues exposed in actual use have become increasingly prominent.

[0003] Currently, the structure of an LED light source includes a lamp housing, an LED light source board, and a driver power supply. The LED light source board includes an aluminum substrate, on which several LED chips are mounted. The circuitry connecting to the driver power supply is also laid on the aluminum substrate. When using an LED light source board, the following problems exist:

[0004] 1. The LED light source board is fixed to the lamp housing with screws. Tools are required for disassembly and assembly, which is cumbersome and inefficient. In particular, if problems occur later, the user experience is poor and replacement is inconvenient.

[0005] 2. The LED light source board is attached to the iron lamp housing by a magnet. The iron lamp housing has a raised magnetic groove. After the magnet is attached to the iron lamp housing, the aluminum substrate is attached to the iron lamp housing. When replacement is needed, the operator has to pry off the aluminum substrate with their fingers, which is difficult to remove and inconvenient to disassemble. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide an easy-to-install and easy-to-disassemble LED light source that is simple to operate, saves time and effort, and is easy to replace.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] An easily replaceable LED light source includes an iron lamp housing, an LED light source board, and a lampshade. The lampshade is installed at the bottom of the iron lamp housing, and the iron lamp housing has wiring holes. The LED light source board includes an aluminum substrate, on which a plurality of LED chips are disposed, and circuitry for connecting to a driving power supply is laid on the aluminum substrate.

[0009] Four magnets and two quick-release structures are fixedly installed on the side of the aluminum substrate without LED patches. The four magnets and the two quick-release structures are located on the same circumference. The iron lamp housing has an annular groove, and the four magnets can be attracted to the bottom of the annular groove.

[0010] Thus, the iron lamp housing and lampshade are existing structures, and the LED light source board includes an aluminum substrate with several LED patches on it. The circuitry connecting the driving power supply is laid on the aluminum substrate, a common structure known to those skilled in the art. To solve the problem of difficult disassembly, quick-release structures are provided on both sides of the aluminum substrate. These structures push the aluminum substrate out, allowing separation from the iron lamp housing, enabling quick removal of the aluminum substrate and replacement of the LED light source board. The operation is simple. During assembly, simply align the magnet with the annular groove; the magnet will attract the bottom of the groove to complete the installation.

[0011] Preferably, the quick-release structure includes a limiting cylinder, a knob, and a support block;

[0012] The aluminum substrate has a mounting hole, the limiting cylinder is coaxially arranged with the mounting hole and fixedly installed on the aluminum substrate, a limiting platform is formed between the limiting cylinder and the aluminum substrate, and limiting blocks are provided on both sides of the upper end of the limiting cylinder.

[0013] The knob slides into the mounting hole. The upper end of the knob protrudes outward and has a convex edge that slides into the limiting cylinder. The convex edge is positioned opposite the limiting platform and has a clearance opening opposite the limiting block. A blind hole is coaxially provided on the knob.

[0014] A rotating shaft is fixedly installed at the lower end of the support block, and the rotating shaft is rotatably engaged with the blind hole. Limiting grooves that slide with the limiting block are provided on both sides of the support block.

[0015] Two axially symmetrically arranged lower arc-shaped blocks are fixedly installed on the upper end of the knob. The upper end of the two lower arc-shaped blocks has an upper inclined surface. Two axially symmetrically arranged upper arc-shaped blocks are fixedly installed on the lower end of the support block. The lower end of the two upper arc-shaped blocks has a lower inclined surface. The upper inclined surface of the lower arc-shaped blocks and the lower inclined surface of the upper arc-shaped blocks slide in contact.

[0016] Preferably, a tension spring is sleeved on the outer side of the rotating shaft, and the two ends of the tension spring are fixedly connected to the knob and the support block, respectively.

[0017] Preferably, the openings of the annular groove in the iron lamp housing are provided with rounded corners on both sides.

[0018] Preferably, the four magnets are arranged in a square.

[0019] In summary, this easily replaceable LED light source has the advantages of being easy to install and remove, simple to operate, and saving time and effort. Attached Figure Description

[0030] like Figure 1-9 As shown, an easily replaceable LED light source includes an iron lamp housing 1, an LED light source board, and a lampshade. The lampshade is installed at the bottom of the iron lamp housing. The iron lamp housing has wire holes. The LED light source board includes an aluminum substrate 2. The aluminum substrate has several LED patches 3. The aluminum substrate has a circuit for connecting to the driving power supply. Four magnets 4 and two quick-release structures 5 are fixedly installed on the side of the aluminum substrate without LED patches. The four magnets and the two quick-release structures are located on the same circumference. The iron lamp housing has an annular groove 6. The four magnets can be attracted to the bottom of the annular groove.

[0031] Thus, the iron lamp housing and lampshade are existing structures, and the LED light source board includes an aluminum substrate with several LED patches on it. The circuitry connecting the driving power supply is laid on the aluminum substrate, a common structure known to those skilled in the art. To solve the problem of difficult disassembly, quick-release structures are provided on both sides of the aluminum substrate. These structures push the aluminum substrate out, allowing separation from the iron lamp housing, enabling quick removal of the aluminum substrate and replacement of the LED light source board. The operation is simple. During assembly, simply align the magnet with the annular groove; the magnet will attract the bottom of the groove to complete the installation.

[0032] In practice, the quick-release structure includes a limiting cylinder 7, a knob 8, and a support block 9;

[0033] The aluminum substrate has a mounting hole 10. The limiting cylinder is coaxially arranged with the mounting hole and is fixedly installed on the aluminum substrate. A limiting platform 11 is formed between the limiting cylinder and the aluminum substrate. Limiting blocks 12 are provided on both sides of the upper end of the limiting cylinder.

[0034] The knob slides into the mounting hole. The upper end of the knob protrudes outward and has a protruding edge 13 that slides into the limiting cylinder. The protruding edge is positioned opposite the limiting platform and has a clearance opening 14 opposite the limiting block. A blind hole 15 is coaxially provided on the knob.

[0035] A rotating shaft 16 is fixedly installed at the lower end of the support block. The rotating shaft is rotatably engaged with the blind hole. Limiting grooves 17 are provided on both sides of the support block to slide with the limiting block.

[0036] The upper end of the knob is fixedly installed with two axially symmetrically arranged lower arc-shaped blocks 18, the upper ends of the two lower arc-shaped blocks having upper inclined surfaces 19. The lower end of the support block is fixedly installed with two axially symmetrically arranged upper arc-shaped blocks 20, the lower ends of the two upper arc-shaped blocks having lower inclined surfaces 21. The upper inclined surfaces of the lower arc-shaped blocks and the lower inclined surfaces of the upper arc-shaped blocks slide in contact.

[0037] In this way, during assembly, the knob is placed inside the limiting cylinder, and when the convex edge is in contact with the limiting platform, the lower end of the knob is located below the aluminum base plate, making it easy to hold. Then, the support block is connected to the knob via a rotating shaft. When the magnet is attracted to the bottom of the annular groove, the support block is in contact with the bottom of the annular groove.

[0038] When disassembling the LED light source board, it is necessary to separate the aluminum substrate from the iron lamp housing. At this time, turn the knob, and the upper and lower inclined surfaces work together to limit the support block through the limiting block, so that the limiting block can only move in the vertical direction. The upper inclined surface pushes the lower inclined surface, increasing the distance between the knob and the support block. Since the support block is in contact with the bottom of the groove, the knob will drive the aluminum substrate to move downward, thereby causing the magnet to disengage from the bottom of the annular groove, and the LED light source board can be quickly removed.

[0039] In practice, a tension spring 22 is fitted onto the outer side of the rotating shaft, with its two ends fixedly connected to the knob and the support block, respectively. The tension spring ensures that the upper and lower inclined surfaces are aligned and in contact, allowing the support block to fit snugly against the bottom of the groove, thus improving the structural reliability.

[0040] In practice, the openings of the annular groove in the iron lamp housing are rounded at both sides. This facilitates the magnet's rapid access to the annular groove, with the rounded corners acting as a guide.

[0041] During implementation, the four magnets are arranged in a square pattern. This improves the installation stability of the LED light source board.

[0042] 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.
