Downlight Thermal Solution
Introduction of downlight:
Downlights also called surface mounted downlights, stage downlights, pendant downlights, embedded downlights, etc.
Downlights generally have a screw base, which can be directly installed with incandescent lamps or energy-saving lamps. Downlight is a type of lighting fixture that is embedded in the ceiling.
The downlight is mainly composed of fin radiator, surface frame, fixed frame, aluminum substrate, LED lamp beads, lens or light diffuser, power supply and other parts.

Glue requirements for downlights:
Glue requirements for downlights:
- Temperature resistance -50~150℃;
- Strong adhesion and sealing to the lampshade;
- The power supply has good waterproof sealing performance;
- It needs to have good conductivity and low oil separation
- The circuit board is moisture-proof, anti-static, shock-proof, dust-proof and mildew-proof.
Glue scheme for downlight:
Downlight glue point | Glue function category | Adhesive glue features |
Drive power | Thermally conductive potting compound | Potting protection, insulation, moisture-proof, shock-proof, dust-proof, anti-corrosion, anti-aging |
Radiator cooling | Thermal Grease | Good thermal conductivity, low oil separation, temperature range -50~180℃ |
lamp cover | Thermally conductive adhesive sealant | High bonding strength and good sealing performance |
circuit board | Three-proof glue | Good protective performance, dustproof, moistureproof, antistatic, shockproof |
According to the material, shape, gluing environment and process of downlight products, the specific glue requirements are also different. For more glue solutions, please contact Cohetion.
