Product Datasheet

Attachment Guide1. Lens to PCB Adhesionroughly
0.05~0.10g Adhesive

Ensure your selected adhesive:

LED-Is silicone based-Has low siloxane levels-Has high viscosity-Has appropriate strength-Is compatible with your processes-Is suitable for the UV environment or is protected from the irradiation

Ensure no floating or tilting of lens before curing
Recommended for opaque or room temp-curing adhesives

2. MechanicalFastener

Secure a plate with a hole of ~5% larger diameter than the lens optic, fitted over the lensCare must be taken to ensure no scraping or other physical damage to the lens optic when mounting

Securing Plate
This method allows easier lens replacement
while preserving the LED, where desired
