Referring to FIGS. 1-13, an LED lamp with a replacement transparent plate bare-handed in accordance with an embodiment of the present disclosure includes a heat sink 10, an LED light board 20 and a transparent plate 30. The LED light board 20 is composed of a plurality of LED beads that is fixed to a circuit board, the LED light board 20 is installed on a front surface 11 of the heat sink 10, and the transparent board 30 is a lens plate and covers on the LED light board 20.

The LED lamp also includes a buckle assembly 40 that includes a base 41, a first limiting portion 414, an elastic member 43 and a fastener 42. The base 41 is fixed to the heat sink 10, and the fastener 42 is movably connected to the base 41. A first end 431 of the elastic member 43 abuts against the base 41 and a second end 432 of the elastic member 43 abuts against the fastener 42. When the buckle assembly 40 is in a first state, a first portion 428 of the fastener 42 presses on the transparent plate 30 to fix the transparent plate 30 to the heat sink 10; and when the buckle assembly 40 is in a second state, a second portion 429 of the fastener 42 is pressed against the first limiting portion 414, and the first portion 428 of the fastener 42 is detached from the transparent plate 30.

By setting the buckle assembly 40, when it is necessary to remove the transparent plate 30, it is only to manually squeeze the fastener 42 horizontally, and when the second portion 429 of the fastener 42 moves to cross a first limiting portion 414, and then the fastener 42 slightly rotates to make the second portion 429 of the fastener 42 abut against the first limiting portion 414, thereby preventing the fastener 42 from being reset. At the same time, the first portion 428 of the fastener 42 is cocked up and detached from the transparent plate 30, at this point, the transparent plate 30 can be manually removed without needing additional tools.

The base41 is arranged on a back surface 12 of the heat sink 10, and the fastener 42 includes a board portion 421 arranged on the back surface 12 of the heat sink 10 and movably connected to the base 41, a connecting portion 422 connected to the board portion 421, and a compressing portion 423 arranged on the front surface 11 of the heat sink 10 and connected to the connecting portion 422; when the buckle assembly40 is in the first state, the compressing portion 423 of the fastener40 presses on the transparent plate 30 to fix the transparent plate 30 to the heat sink 10.

The fastener 42 further includes a second limiting portion 425 connected to the board portion 421, and when the buckle assembly 40 is in the second state, the second limiting portion 425 abuts against the first limiting portion 414, which can prevent the fastener 42 from being reset, so that the transparent plate 30 can be manually removed.
