Thermal Management Products for LEDs

The thermal management of the LED and the unit is a vitally important consideration for the reliability of an LED unit.
  • Thermal Pastes
  • Phase Change Material
  • Gap Pads
  • Thermal Bonding
  • RTVs
  • Encapsulation Resins

The thermal management of the LED and the unit is a vitally important consideration for the reliability of an LED unit. A variation of just one single degree centigrade can effect both the life of the LED, (the higher the temperature the unit is running at the faster the luminaire degrades) as well as the efficiency, ( the lower the temperature, the more efficient the luminaire is at producing light).

With a single degree centigrade of heat having such a large effect on the efficiency and the lifetime of an LED Luminaire, the thermal interface material chosen for the LED design is of vital importance.

Electrolube offer a wide range of thermal interface materials including curing and non-curing pastes, gap pads, phase change materials (facilitating easy rework), as well as a selection of encapsulation resins which are designed to dissipate the heat away from the components to the housing.

If you have any questions our dedicated technical support team are on hand to answer your questions and don’t forget that our LED brochure contains vast amount of collaborative test data from Bridgelux comparing data to help you select the right material.
