Be provided with first spout 141 on the mounting bracket 14, be provided with first arch 33 on the lens holder 3, lens holder 3 slides in first spout 141 through first arch 33, be provided with second spout 142 on the mounting bracket 14, be provided with the protruding 40 of second on the lamp shade 4, lamp shade 4 slides in second spout 142 through the protruding 40 of second, first spout 141 and the setting of second spout 142 along mounting bracket 14 length direction on the mounting bracket 14, the protruding entering that can effectively prevent outside water and outside dust with the cooperation of spout.

Further, the heat sink 1 further includes a cover plate 15, and the cover plate 15 covers the side surfaces of the heat sink 1, the lens holder 3, and the lamp housing 4. The cover plate 15 can fix the lens holder 3 and the globe 4 to prevent them from sliding in the slide grooves. Further, a threaded hole 143 is formed in the mounting frame 14, and the cover plate 15 is in threaded connection with the mounting frame 14 through the threaded hole 143.

Referring to fig. 12, 13, 15 and 16, the cover plate 15 is connected to the lamp housing 4 by a first waterproof mechanism for preventing external water from entering the heat sink 1 and the lens 30. Specifically, the first waterproof mechanism includes a first waterproof groove 41 disposed on the lamp shade 4 and a first waterproof protrusion 151 disposed on the cover plate 15, and the first waterproof groove 41 and the first waterproof protrusion 151 cooperate to achieve waterproofing of the lamp shade 4.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
