• Manufacturer Part Number: 210-10PKT
• Description: LUXEON Rebel 14mm Linear +/-15O (30 Deg) LED Collimator Optic
• Manufacturer: Polymer Optics

Application Notes:
It should be noted that the thermal coefficient of expansion of polycarbonate (3.75 x 10
than the typical thermal coefficient of expansion for an aluminium alloy extruded housing/heatsink (23.2
x 10
As a guide, a 1200mm long section of the polycarbonate extrusion will expand by 0.045mm/
temperature, where an aluminium extruded housing of the same length will expand by 0.0278mm/
Therefore the difference in linear expansion will be 0.0172mm/
So, if the 1200mm fitting experiences a temperature rise of 40
expand by around 0.7mm more then its aluminium housing. It is therefore recommended that some
expansion clearance is allowed on the overall length of the Linear Optic in its housing.
Expansion gaps left at the ends of the Linear Optic, or gaps between lengths assembled end to end, can
be filled with a silicone based elastomer material or similar flexible sealant/adhesive to allow for the
expected expansion movement.
