An aluminum substrate is arranged inside the rear cover, and the LED lamps are installed on the aluminum substrate, and the annular radiator is surrounded by a plurality of cooling fins arranged at intervals, and the cooling fins include a hollow cylindrical base and are arranged outside the hollow cylindrical base, and along the hollow cylindrical The heat dissipation fins on the axial direction of the type base, the heat dissipation fins extend from the rear cover to the front cover, and the width of the heat dissipation fins along the extending direction gradually increases, the aluminum base plate and the hollow cylindrical base bottom contact.

Further, the rear cover is provided with a plurality of cooling holes.

Further, the front cover is covered with a reflective plate for anti-dizziness.

Further, the lower end of the lamp body is provided with a first connecting lug, and the first connecting lug is provided with a screw hole, and the upper end of the lamp holder is provided with a second connecting lug, and the second connecting lug is provided with a screw hole. Screw holes are also provided, and the first connecting lug and the second connecting lug are movably screwed through bolts.

Further, the lower end of the lamp holder is a hollow suction cup structure, and the two ends of the base of the suction cup structure are provided with threaded connection holes for fixing to the installation site by screws.

detailed description

The idea, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, characteristics and effects of the present utility model. Apparently, the described embodiments are only some embodiments of the present utility model, rather than all embodiments, and other embodiments obtained by those skilled in the art without paying creative work all belong to the protection scope of the present utility model .

As shown in Figures 1 and 2, an LED lamp includes a lamp body 1 and a lamp holder 2. The lamp body 1 includes a front cover 11, a rear cover 12, and a ring-shaped radiator connecting the front cover and the rear cover. A radiator 13, an aluminum substrate is arranged inside the rear cover 12, and an LED lamp is installed on the aluminum substrate, and a plurality of cooling fins 131 arranged at intervals are surrounding the annular radiator 13, and the cooling fins 131 include hollow cylinders Type base 1311 and cooling fins 1312 arranged on the outside of the hollow cylindrical base and along the axial direction of the hollow cylindrical base 1311, the cooling fins 1312 extend from the rear cover 12 to the front cover 11, And the width of the cooling fins 1312 along the extending direction increases gradually, and the aluminum base plate is in contact with the lower end of the hollow cylindrical base. The arc-shaped edges around the hollow cylindrical base 1311 can better form a heat conduction flow to dissipate heat. At the same time, the hollow cylindrical base 1311 can be filled with heat-absorbing materials, which is more conducive to the heat dissipation of the LED lamp. The width of the heat dissipation fins is gradually widened to expand the heat dissipation area. The rear cover is provided with a plurality of cooling holes 121 . Allow some of the heat to dissipate through the back.

The front cover is covered with a reflector for preventing dizziness.

The lower end of the lamp body 1 is provided with a first connecting lug 14, and the first connecting lug 14 is provided with a screw hole, and the upper end of the lamp holder 2 is provided with a second connecting lug 21, and the second connecting lug 21 is provided. Screw holes are also provided on the ear 21 , and the first connecting lug 14 and the second connecting lug 21 are movably screwed together by bolts.

The lower end of the lamp holder 2 is a hollow suction cup structure, and the two ends of the base of the suction cup structure are provided with threaded connection holes 22 for being fixed on the installation site by screws.

When using the LED lamp, the base can be selectively fixed and installed on the installation surface, or the base can be sucked on the installation surface through the suction cup structure, which is convenient for people to use.

It should be noted that the above description is only a preferred embodiment of the utility model, and the utility model is not limited to the above-mentioned embodiment, as long as it achieves the technical effect of the utility model by the same means, it should belong to the utility model scope of protection.
