CooLam® 3D Thermal Substrate

Bendable Thermal Substrate Allows LED Lighting Designers to Direct and Control Light Output

The key to LEDs delivering on their promise of longer life and more effiecient electrical performance is in controlling and dissipating heat inside the LED chip package.

The most effective way of doing that is with thermal substrate materials that dissipate heat conductively through the package. 

DuPont™ CooLam® 3D thermal substrates for bendable metal core printed circuit boards (MCPCBs) are ideal for applications requiring innovative lighting designs that direct light output without secondary optics, as well as low thermal impedance and superior electrical performance at a competitive cost.

This bendable thermal substrate offers higher quality of light and exceptional freedom of design. Ideal for innovative omnidirectional A-19 replacement bulbs and general lighting fixtures.
