Mechanical Assembly and Handling
Recommended assembly is illustrated below.
When handling parts, please avoid contacting and do not apply stress to the resin area (see Figure 1,
resin area is indicated in yellow).
Product should be firmly secured onto appropriate heat sink by fastening M2.5 or #4 screws on both sides
of the product as illustrated in Figure 16. The recommended center-to-center spacing for these the two
tapped holes for mounting screws is 19.20 ± 0.05mm for hexagonal star products and 26.92 ± 0.10mm for
rectangular array products. Bridgelux recommends the use of hard non-electrically conductive flat
washers with lock washers. Refer to Application Note AN11 – Handling and Assembly of Bridgelux LED
Arrays, for more details.
A thin layer of thermal grease should be applied to the bottom surface of the LED Array, between the
bottom of the array and the heat sink. All air gaps and voids between the heat sink and array should be
eliminated. Ensure that sufficient thermal grease is used to cover the entire bottom surface of the array,
but not so much that the thermal grease creeps up to the top of the array.
