SlimRay™ pre-wired LED array holders with a low profile stepped design for use with Lumileds LUXEON and similar next generation COB arrays. These SlimRay™ LED array holders feature pre-wired high pressure gold plated crimped terminals that eliminate the need for hand soldering and resultant damage to the COB during the process and a robust reflective white thermoplastic connector housing to promote light output. Additonal features of these SlimRay™ LED array holders include an LED Chip-on-Board (COB) pre-hold feature that allows the LED array to be fitted to the holder during final assembly, a flat-top surface with integrated bevel that surrounds the LES that provides seating for the optics and aids light output and a simple screw mount attachment for securing to a heatsink. Typical applications for these SlimRay™ pre-wired Lumileds LUXEON LED array holders include general illumination eg downlighting and spotlighting and area lighting eg roadways and carparks
