This application claims priority of Chinese Patent Application No. 202311442698.8, filed on Nov. 1, 2023, entitled “LED LAMP”, the entire content of which is incorporated herein in its entirety.

TECHNICAL FIELD

The present disclosure relates to lighting devices, and in particular to an LED lamp.

BACKGROUND

LED lamps have many advantages such as energy saving, environmental protection and long life, and have been widely used in various lighting places. In actual use, a lens plate needs to be replaced to convert different luminous effects. However, in the prior art, there are the following shortcomings when replacing the lens plate.

• • 1) Since an LED lamp panel is connected to a power supply, an operator may be at risk of electric shock when replacing the lens plate.
  • 2) Most of the existing lamp manufacturing technologies are fully fixed products. The components of the lamp are completely fixed in the factory. If the components of the lamp need to be replaced, the lamp needs to be disassembled in a multi-step process. The components fixed by screws need to be disassembled and assembled using tools, which is inconvenient and time-consuming. It is difficult to replace the lens plate of the LED lamp quickly and conveniently.

SUMMARY

Accordingly, it is necessary to provide an LED lamp that is safe and convenient for replacing a lens plate.

An LED lamp includes: a heat dissipation lamp holder provided with a mounting groove on a front side thereof; an LED lamp panel mounted in the mounting groove; a driving power supply electrically connected to the LED lamp panel and configured to power the LED lamp panel; a switch assembly located on the heat dissipation lamp holder and electrically connected between the LED lamp panel and the driving power supply; and a lens plate located on a side of the LED lamp panel emitting light and capable of abutting against the switch assembly. The switch assembly disconnects the LED lamp panel from the driving power supply when the lens plate is separated from the switch assembly, and the switch assembly electrically connects the LED lamp panel and the driving power supply when the lens plate abuts against the switch assembly.

Since the switch assembly is provided between the LED lamp panel and the driving power supply, and the switch assembly is pressed by the lens plate, when the LED lamp panel needs to be removed for maintenance or replacement, the lens plate is separated from the switch assembly, so that an internal circuit of the switch assembly is disconnected, thereby disconnecting the LED lamp panel from the driving power supply, and thus preventing human hands from getting an electric shock due to being in contact with the LED lamp panel.

Referring to FIGS. 1 to 7, an LED lamp according to a first embodiment is provided, including a heat dissipation lamp holder 1, an LED lamp panel 2, a driving power supply 3, and a switch assembly 5. The driving power supply 3 is configured to power the LED lamp panel 2. A front side of the heat dissipation lamp holder 1 is provided with a mounting groove 4, and the LED lamp panel 2 is mounted in the mounting groove 4. The switch assembly 5 is electrically connected between the LED lamp panel 2 and the driving power supply 3. The switch assembly 5 is located on the heat dissipation lamp holder 1. The LED lamp further includes a cover member located on a side of the LED lamp panel 2 emitting light. In this embodiment, the cover member is a lens plate 6 having a lens structure. The lens plate 6 is capable of abutting against the switch assembly 5. When the lens plate 6 is in an open state, that is, when the lens plate 6 is separated from the switch assembly 5, the switch assembly 5 disconnects the LED lamp panel 2 from the driving power supply 3.
