Tyco Electronics has a solderless LED socket designed specifically for use with the Philips Lumileds LUXEON S LED.

The Type LS socket complies with UL-1977 specifications and is designed with insulation displacement technology to allow for quick and easy termination of 24 AWG wires to the socket. 

An integral stainless steel spring within the socket is designed to provide a uniform and adequate normal force to the LED.

To position the LED on a heat sink a plastic frame that is first placed on the heat sink to correctly orient the LED in its position prior to socket attachment. Once positioned, only three commercially-available #4 or M3 screws are needed to rapidly secure the socket to the heat sink.

Designed to maximize optical efficiency in un-lensed applications, the shape of the Type LS socket ensures that 98 percent of the light emitted from the LED is unobstructed.
