Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to an LED lamp. Background Technology

[0002] As a new type of solid-state lighting device, LED lamps mainly consist of five core components: lamp housing, light-transmitting cover, LED light-emitting module, driver power supply, and hanging bracket. The lamp housing, as the main load-bearing structure, is typically made of aluminum alloy or engineering plastics; the light-transmitting cover is mostly made of polycarbonate (PC) or polymethyl methacrylate (PMMA), combining light transmission and protection; the LED light-emitting module includes a substrate and an array of LED chips; the driver power supply module realizes power conversion and regulation; and the hanging bracket is fixed to the ceiling to suspend the lamp housing.

[0003] Light-transmitting covers tend to accumulate dust and dirt, requiring disassembly and cleaning after a period of use to prevent impact on lighting performance. Currently, the connection between the light-transmitting cover and the lamp housing is generally achieved through snap-fit ​​assembly or threaded fastening. While snap-fit ​​structures offer the advantage of quick installation, prolonged use can lead to increased clearance due to loss of elasticity at the snap joint, creating a channel for dust and oil intrusion. Threaded connections, after repeated disassembly and assembly, suffer from reduced screw tightening torque, even stripping, and require tools for disassembly and assembly, making operation inconvenient. Utility Model Content

[0004] 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 lamp that is easy to install and remove the lampshade, simple to operate, and has a stable structure.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An LED lamp includes a lamp housing, an LED light-emitting module, a driver power supply, a light-transmitting cover, and a hanging bracket. The hanging bracket is fixedly installed on the ceiling using expansion screws. The lamp housing includes an outer frame and a partition fixedly installed inside the outer frame.

[0022] 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.

[0023] like Figure 1-8 As shown, an LED lamp includes a lamp housing, an LED light-emitting module, a driver power supply, a light-transmitting cover 1, and a hanging bracket 2. The hanging bracket is fixedly installed on the ceiling by expansion screws. The lamp housing includes an outer frame 3 and a partition 4 fixedly installed inside the outer frame. The LED light-emitting module is fixedly installed at the lower end of the partition. The partition has a through-hole for wiring. The driver power supply is located above the partition, and one end of the driver power supply is wired through the through-hole and connected to the LED light-emitting module. An inner frame 5 is fixedly installed at the lower end of the partition. The inner frame is spaced apart from the outer frame, and the inner frame is located inside the outer frame, forming an installation space between the inner frame and the outer frame. The lower ends of the inner frame and the outer frame are sealed by a sealing frame 6. A support frame 7 is provided below the sealing frame, and a support platform 8 is provided inside the support frame. The light-transmitting cover is placed on the support platform. Both sides of the support frame are connected to the sealing frame by two connecting structures.

[0024] In this configuration, the LED light-emitting module and driver power supply form the main structure of the lamp, which is existing technology. The LED light-emitting module is fixedly installed below the partition, while the driver power supply is located above the partition, and the LED light-emitting module is connected to the driver power supply. During installation, the bracket is fixedly installed on the ceiling, then the lamp housing is fixedly connected to the bracket. Next, the light-transmitting cover is placed on the support platform of the bracket, and then the bracket is connected to the sealing frame via a connecting structure to complete the assembly. No additional tools are required. When cleaning the light-transmitting cover is needed, the bracket can be disassembled to remove the cover. The sealing frame design prevents light leakage, allowing light to pass through the light-transmitting cover more effectively.

[0025] In implementation, the connecting structure includes an inner cylinder 9 fixedly installed on the support frame, a limiting ring 10 fixedly installed on the outer side of the inner cylinder, a limiting hole opened in the sealing frame, one end of the limiting hole being a circular hole 11 that allows the limiting ring to pass through, and the other end of the limiting hole being an elongated hole 12 that slides with the cylinder, the limiting ring being spaced apart from the support frame and the gap between the limiting ring and the support frame being greater than the thickness of the sealing frame.

[0026] In this way, when connecting the support frame and the sealing frame, the inner cylinder and the limiting ring on the support frame are aligned with the circular hole, with the limiting ring passing through the circular hole. Then, the support frame is pushed laterally, causing the inner cylinder to move into the elongated hole and reach the end away from the circular hole. At this point, the limiting ring overlaps the support frame, preventing the support frame from falling off. The gap between the limiting ring and the support frame is greater than the thickness of the sealing frame, allowing the limiting ring to be positioned more effectively above the sealing frame.

[0027] Preferably, a compression spring 13 and a pin 14 are provided inside the inner cylinder, the upper end of the pin is rounded 15, and the two ends of the compression spring are fixedly connected to the support frame and the pin respectively.

[0028] The partition is fixedly installed with a limiting block 16 opposite the limiting hole. The limiting block has an upper plane 17 opposite the circular hole and a lower plane 18 opposite the limiting hole at the end away from the circular hole. The upper plane and the lower plane are connected by an inclined plane 19. The pin can slide along the upper plane and the inclined plane to the lower plane and abut against the lower plane.

[0029] In this way, through the arrangement of the compression spring and the pin, when the inner cylinder and the limiting ring pass through the circular hole, the upper end of the pin contacts the upper plane. During the lateral movement of the support frame, the pin moves along the upper plane and the inclined plane to the lower plane, finally contacting the lower plane. Since the upper end of the pin is flat, it makes full contact with the lower plane, resulting in high stability. The rounded corners facilitate the movement of the pin, and the compression spring ensures a stable fit between the pin and the lower plane, further improving the reliability of the connection. When it is necessary to disassemble the support frame, simply push the support frame in the opposite direction.

[0030] During implementation, the sealing frame is welded to the inner and outer frames. Laser welding can be used, which facilitates connection and avoids light leakage.

[0031] In implementation, the main body of the hanger is I-shaped, with the ends bent to form connecting ends 20. A threaded hole 21 is provided through the connecting end, and a through hole 22 is provided directly opposite the threaded hole on the outer frame. The outer frame and the hanger are fixedly connected by screws. The I-shaped hanger, combined with multi-point screws for connection to the outer frame, ensures high connection stability.

[0032] 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.
