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:

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.
