Prewired LED array holder

16 July 2014 Interconnection

Molex has released details about an innovative LED array holding concept for LED lighting manufacturers using chip-on-board (COB) technology.

Given that a key design challenge for high-performance LED accent lighting luminaires is to get secondary optics very close to the light emitting surface of the LED, any reduction in the distance between the LED and the optics results in tighter beam control and higher luminous efficacy.

First-generation LED COB holders have enabled many applications, using reasonably low profile heights, but the new Molex prewired model takes it a step further, reducing the height of the holder by optimising the entire contact system. As a result, optics can be placed much closer to the LED, with a positive effect on both the quality of light as well as the light output. The holder body is made from a highly reflective, white moulding material to further enhance light output.

With this system, the height profile is limited primarily by the thickness of the wire selected. Wires need not be inserted at the holder during assembly, as they are an integral part of the holder, providing maximum wire-to-holder retention forces. The free ends can be stripped, tinned or terminated with another connector, such as a Molex Micro-Fit or Mizu P25.

The new holders come with an LED pre-load feature that allows seating of the LED before final assembly. This reduces assembly time and prevents quality issues caused by misalignment. The new compact system also allows flexibility in footprint size – from small, space-saving diameters to 50 mm Zhaga-type or larger – with a wide range of optical attach possibilities.
