As shown in FIGS. 3 to 9 , the bottom of the lamp body 10 is provided with a fixing groove 13 for accommodating the fixing member 60 , and the fixing groove 13 is communicated with the aforementioned gap a. The purpose of this setting is to make the mask 40 and the lamp body 10 connect. The accumulated water between the two can flow out from the gap a and the fixing groove 13, which has the effect of automatic drainage. In order to ensure smooth drainage, the present application sets the space of the fixing groove 13 to be large enough to ensure that when the fixing member 60 is accommodated in the fixing groove 13 , there is a gap a between the inner wall surface of the fixing groove 13 and the fixing member 60 . Therefore, regardless of whether the fixing member 60 is accommodated in the fixing groove 13 or not, the accumulated water between the mask 40 and the lamp body 10 can flow out from the gap a and the gap b, ensuring the drainage effect.

Preferably, the mask 40 is a glass mask; the second accommodating cavity 12 is an annular rubber strip groove; the fixing groove 13 at the bottom of the lamp body 10 is a through hole; of course, the mask 40 can also be made of other materials, such as plastic; the fixing groove 13 can also be in other forms, as long as the fixing member 60 can be accommodated and a gap b is reserved, and there is no excessive limitation here.

As shown in FIG. 7 and FIG. 8 in combination with FIG. 5 , the pressing member 50 is generally arranged in a T-shape, including a pressing portion 51 for pressing the mask 40 and an installation extending downward from one end of the pressing portion 51 . part 52 , the pressing part 51 protrudes toward the side of the mask 40 for abutting with the upper surface of the mask 40 . The mounting portion 52 is arranged in a column shape and extends into the lamp body 10, and the bottom of the mounting portion 52 is provided with an insertion hole 521 for the fixing member 60 to be inserted into. The bottom of the body 10 is installed into the fixing groove 13 , and then inserted into the insertion hole 521 on the pressing piece 50 to fix the pressing piece 50 and the lamp body 10 .
