Usage of silicone encapsulants
Sensitive LED's need protection from moisture and other harsh environmental hazards. This protection is normally provided on two levels, the micro and macro. Our silicones can also be used to improve the light output and overall optical efficiency of the device.
Micro level
In these applications clear silicone gels and elastomers are used to encapsulate individual diodes. In addition to providing protection they can be used to improve the light output of the LED. Silicones with a high refractive index or one that is matched to the lens material, produce significant improvements. Silicones used at the micro level may also be required to have very low ionic content which will reduce the risk of interference with the electrical properties of the diode.
Any yellowing of the encapsulant due to heat exposure or UV light will also have a ***rimental effect on the light output and particularly, the colour temperature index of the light produced by the LED. Modern reflow soldering of diodes onto PCB's requires temperatures up to 260oC which can cause this discoloration in epoxy and other resin based encapsulants, but not silicones.
The delicate wire connections between PCB and diode are vulnerable to mechanical stress caused by fluctuations in temperatures therefore, it is also important the chosen encapsulant has low modulus properties and a high Coefficient of Thermal Expansion (CTE).
