Description

Technical Field

[0001] The utility model relates to the field of lighting devices, in particular to an LED lamp with safe and convenient lens plate replacement. Background Art

[0002] LED lamps have many advantages such as energy conservation, environmental protection and long service life, and have been widely used in various lighting places. In actual use, the situation faced is the need to replace the lens plate to convert different lighting effects. However, in the prior art, there are the following deficiencies when replacing the lens plate:

[0003] 1) Since the LED lamp board is connected to the power supply and is charged, the operator may have the risk of electric shock during the process of replacing the lens plate.

[0004] 2) Most of the existing lamp manufacturing technologies are fully fixed products. The components of fully fixed lamps are completely fixed before leaving the factory. If component replacement of the product is involved, multi-step disassembly of the lamp is required. Components fixed by screws need to be disassembled and assembled with tools, which is not convenient for disassembly and relatively time-consuming. It is difficult for LED lamps to replace the lens plate quickly and conveniently. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an LED lamp with safe and convenient lens plate replacement.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is:

[0007] An LED lamp, comprising a lamp base, an LED lamp board, a light-transmitting plate and a driving power supply. The driving power supply and the LED lamp board are installed on the lamp base. The driving power supply is used to supply power to the LED lamp board. The light-transmitting plate covers the LED lamp board. It further comprises a pressing frame which presses the light-transmitting plate, and the pressing frame is fixed on the lamp base through a quick disassembly and assembly structure.

[0008] Preferably, the quick disassembly and assembly structure comprises a clamping block arranged on the pressing frame and a fixing seat arranged on the lamp base. A clamping groove is arranged on the fixing seat, and the clamping block is clamped with the clamping groove;

[0009] When the pressing frame is in the first state, the clamping block is clamped with the clamping groove;

[0010] When the pressing frame is in the second state, the clamping block is disengaged from the clamping groove.

[0011] When the light-transmitting plate needs to be replaced, simply manually rotate the pressing frame counterclockwise so that the clamping block on the pressing frame disengages from the clamping groove on the fixed seat, and remove the pressing frame. At this time, the light-transmitting plate can be removed for replacement or repair without the aid of tools. Conversely, when the light-transmitting plate needs to be installed, place the light-transmitting plate in the installation position, then manually cover the light-transmitting plate with the pressing frame and rotate the pressing frame clockwise. At this time, the clamping block on the pressing frame is clamped with the clamping groove on the fixed seat, so that the light-transmitting plate can be fixed on the lamp body. The operation is simple and fast, and no other tools are needed.

[0012] Preferably, a positioning plate is extended and provided on the edge of the light-transmitting plate, and a positioning groove is provided at the position corresponding to the fixed seat.
