Detailed ways:

In order to deepen the understanding of the present utility model, the present utility model will be further described in detail below with reference to the implementation cases and accompanying drawings. The utility model can be implemented in the following ways:

1-6, a side-emitting LED downlight with good heat dissipation effect includes a heat dissipation shell 1 and a heat dissipation base plate 2 arranged at the bottom of the heat dissipation shell 1. The heat dissipation shell 1 is a circular aluminum shell , can achieve rapid heat conduction. A detachable and transparent cover plate 3 is disposed on the opening of the heat dissipation casing 1 , and a side light source 4 is disposed at the position of the heat dissipation casing 1 in contact with the side surface of the cover plate 3 . The side-emitting light source 4 is a ring-shaped light strip, and the light emitted by the lamp beads on the side-emitting light source 4 enters the cover plate 3 through the transparent cover plate 3, so that the cover plate 3 forms surface light emission. The heat-dissipating housing 1 is provided with a light source sticking wall 11 for attaching the side-emitting light source 4, the light source is arranged in an annular shape, and is pasted on the light-source sticking wall 11 of the heat-dissipating housing 1 to form the side-emitting light source 4, This design can dissipate the heat of the side-emitting light source 4 to the outside through the heat dissipation shell 1 and the heat dissipation base plate 2, and the heat dissipation effect is good. The heat dissipation shell 1, the heat dissipation base plate 2 and the cover plate 3 constitute the downlight body. The thickness of the downlight body is in the range of 8-15mm, so as to achieve an ultra-thin effect, the space required for installation is small, and the scope of application is small. wide.

A heat-dissipating connecting column 12 is arranged between the light source sticking wall 11 and the heat-dissipating housing 1 . The entire heat dissipation shell 1 is integrally formed, and the heat dissipation connecting column 12 can quickly conduct the heat transferred from the side-emitting light source 4 to the light source sticking wall 11 to the entire heat dissipation shell 1, which further accelerates the conduction of heat and improves the heat dissipation effect.

The cover plate 3 is provided with a printing layer on the bottom surface facing the heat dissipation base plate 2 . The printed layer can not only reduce the emission of light from the back of the downlight and ensure that the light can be emitted from the front of the downlight, but also has a better decorative effect.

The top of the heat dissipating housing 1 extends radially inwardly with a clipping portion 13 for clipping the cover plate 3 . The clamping portion 13 can prevent the cover plate 3 from falling off after the downlight is installed.

The heat dissipation base plate 2 is made of fast heat dissipation material. The bottom of the heat dissipation base plate 2 is provided with a plurality of heat dissipation strips 21, which can increase the contact area between the heat dissipation base plate 2 and the outside air, and further improve the heat dissipation effect.
