Thermal solution for solar lamps
Introduction of solar light:
Solar lights are electric lights that are converted into electricity by solar panels. During the day, even on cloudy days, this solar generator (solar panel) can collect and store solar energy. As a kind of safe and environmentally friendly new electric light, solar light has been paid more and more attention.
The solar light is composed of solar cell components, some LED lamps, a control box (which has a charger, a controller, and a battery in the control box) and a light pole.
As we all know, LED is the most energy-efficient illuminant today, which is widely used in household, automobile, industry, city, aerospace and other fields. In LED lighting products, adhesives mainly play the functions of bonding, sealing, heat conduction, flame retardant protection and so on. The quality of the adhesive solution directly determines the safety and stability of the lighting product, atomization and light transmission, aging and durability.
Glue requirements for solar lamps:
- Power potting insulation and heat conduction;
- Strong adhesion and fixation to components;
- Excellent heat dissipation for heating components;
- Environmental protection, non-toxic, with routine testing certification and qualifications;
- Moisture-proof, anti-static, dust-proof, mildew-proof, salt spray resistance, etc. for circuit boards.
Glue scheme for solar lamps:
| Glue dots for solar lamps | Glue function category | Features of glue application |
| cooling module | Thermal Grease | Has good thermal conductivity, temperature range -40~200℃ |
| Solar panel and chassis frame | Thermally conductive adhesive | Good adhesion, good adhesion to plastic aluminum, copper, stainless steel and other metals, excellent deformation resistance |
| power module | Thermally conductive potting compound | Potting protection, no by-products are produced during the curing process, and can play the role of insulation, moisture-proof, anti-corrosion and anti-aging |
| PCB circuit board | Three-proof glue | Good protection performance, good high and low temperature resistance, and has the characteristics of dust-proof, moisture-proof, anti-static, shock-proof, etc. |
| Electronic Components | fixing glue | High bonding strength, excellent dielectric properties, good heat resistance, and will not corrode electronic components |
According to the material, shape, gluing environment and process of solar lamp products, the specific glue requirements are also different. For more glue solutions, please contact Cohetion.
