Background technique

As a new generation of green lighting fixtures, downlights have the advantages of energy saving, environmental protection, and long life, and are currently being used more and more.

The light source component template of the existing downlight is fixed on the heat dissipation base through a heat-conducting silica gel sheet or heat-conducting silicone grease. The heat-conducting silica gel sheet is used for easy installation and small tolerance, but the heat dissipation effect is poor. This is due to the low thermal conductivity of the heat-conducting silica gel. Although the use of thermal conductive silicone grease is better in heat dissipation adjustment than thermal conductive silicone, but the paste-like thermal conductive silicone grease is easy to dirty the surrounding devices during use and cause short circuits, and when reinstalling, it is necessary to scrape off the original thermal conductive silicone grease to apply new thermal conductive silicone. Grease is not only troublesome but also easy to scratch electronic components.
