CX Family Design guiDe
MECHANICAL DESIGN
Typical Assembly
CX family LEDs are generally attached directly to a heat sink and discrete wires are used to deliver power to the LED, as illustrated in
Figure 1. A thermal interface material (TIM) must be applied between the CX family LED and the heat sink to properly maintain thermal
performance.
Without the use of a connector to attach a CX family LED to a heat sink, apply thermal adhesive or thermal tape between the CX family
LED and the heat sink.
With a connector, apply thermal adhesive, thermal tape, a thermal pad, thermal grease, gel, gap ller or heat spreader between the CX
family LED and the heat sink.

Connectors
The use of a connector to attach a CX family LED to a heat sink simplies the mechanical fastening of the CX family LED to the heat sink
and can help with aligning a secondary optic with the LES. The use of a connector can also ensure proper clamping force is applied to the
CX family LED, minimizing the potential for damage. Additionally, because a connector covers the LED’s electrical connections, use of a
connector simplies the safety and regulatory certication process.
Connector Resources
Table 1 contains model numbers and characteristics for connectors available from Interconnect Solution Providers that participate in the
CSP program. Each supplier name and model number is a link to additional information on the connector. These suppliers can provide
assistance with connectors and connector information.
