Detailed ways

In order to facilitate the understanding of those skilled in the art, the structural principle of the present utility model will be further described in detail below in conjunction with specific embodiments and accompanying drawings:

Embodiment 1: As shown in accompanying drawings 1 and 2, this embodiment mainly includes a lampshade 1, the cross section of which is a square, and the front of the lampshade 1 is sequentially installed with a waterproof gasket 6, a glass sheet 2 and an upper cover 9, and the back of the lampshade 1 A radiator 5, a radiator cover 7 and a fixed handle 8 are installed on the top, and a lamp holder 3 for fixing a light bulb 4 is installed at the inner bottom of the lampshade 1.

The upper cover 9 is a square fixed frame structure, and the frame is provided with through holes 91 for inserting screws. There are also threaded holes 11 corresponding to the through holes 91 and a channel 14 for installing the waterproof gasket 6 on the front edge of the lampshade 1. By fixing with screws, the upper cover 9 and the glass sheet 2 can be fixed on the front of the lampshade 1, and the glass Seal between sheet 2 and lampshade 1 .

The heat sink 5 and the lampshade 1 are also fixed by screws. In order to prevent water flow from entering the interior of the lampshade 1 through the holes for inserting the screws at the bottom of the lampshade 1, a waterproof gasket 6 is also provided on the periphery of the contact surface between the lampshade 1 and the heat sink 5; At the same time, the threaded holes for fixing screws on the heat sink 5 are opened in the form of counterbore holes, that is, threaded counterbore holes 51 .

In order to promote the flow of air in the heat sink 5 and increase the heat dissipation effect, a heat sink cover 7 is also installed on the heat sink 5 . The heat sink cover 7 of this solution is an n-type bent metal sheet, which is parallel to the heat sink 5 and straddles both sides of the heat sink 5 . This installation structure is conducive to the formation of a wind tunnel effect between the heat sink cover 7 and the heat sink 5, which can greatly improve the air flow in the heat sink 5 and increase the heat dissipation effect. At the same time, in order to further increase the heat dissipation effect, the fixed handle 8 is also installed on the heat sink 5 , and part of the heat can be dissipated through the fixed handle 8 . Of course, the fixed handle 8 is a metal product that is conducive to heat conduction. Both ends of the fixed handle 8 are fixed on both sides of the heat sink 5 by screws, and the contact part between the fixed handle 8 and the screw nut is provided with anti-slip embossing 81 to prevent the fixed handle 8 from rotating relative to the screw.

A stepped hole 11 through which electric wires are inserted is opened on the lampshade 1 , and a sealing screw 12 and a sealing gasket 13 are tightly screwed in the stepped hole 11 . The middle of the sealing screw 12 is provided with a circular hole 121 through which a wire is inserted, and the threaded end surface of the sealing screw 12 is provided with an arc-shaped depression 122 . The gasket 13 is spherical or hemispherical. When the sealing screw 12 is tightened and installed, the sealing gasket 13 is deformed toward the center of the arc-shaped depression under the extrusion of the end surface of the screw thread and the arc-shaped depression, so that the sealing gasket 13 is tightly filled at the junction of the round hole 121 and the stepped hole 11 and Tighten the outer circumference of the wire to prevent water from entering the lampshade 1 along the wire, the round hole 121 and the stepped hole 11.

Simultaneously, in order to enhance the light irradiation effect according to needs, the bulb 4 is installed in an optical lens 41, and the optical lens 41 is a concave mirror that is beneficial to light divergence or a convex mirror that is beneficial to light convergence, and its specific form can be determined according to the needs of the environment.

Naturally, in this embodiment, the lampshade 1 used can be configured as a bottomless structure. That is, the lamp holder 3 is directly installed on the heat sink 5, and the connection form of other components remains unchanged. Since the lamp holder 3 is in direct contact with the heat sink 5, the heat dissipation effect is better. Of course, the heat sink cover 7 can be T-shaped or two symmetrical L-shaped metal sheets, so that the wind tunnel effect can be generated between the heat sink cover 7 and the heat sink 5 .

Embodiment 2: As shown in accompanying drawings 3 and 4, compared with Embodiment 1, this embodiment differs in that the lampshade 1, the waterproof gasket 6, the glass sheet 2 and the heat sink 5 are all circular, and the heat sink is eliminated. The cover 7 and upper cover 9, other parts and their connections are consistent with those in Embodiment 1, and will not be repeated here.
