Lumileds line and area sources for LED lighting
Lumileds has started to make multi-LED area and line light sources, based around 3535L surface mount LEDs on ridged and flexible PCBs.
Luxeon XR (below) is the name of the rigid line, and the flexies are Luxeon XF (right).
XR-3535L is first out of the traps. Designed for Zhaga compliant assemblies and aimed at troffers, it comes in 3,000, 3,500 or 4,000K colour temperature with a CRI of 80. Output is 1,320 to 1,515 lm and maximum efficacy is 160 lm/W. LEDs are connected as a parallel combination of three strings, each of 11 LEDs. These are arranged as a 11×3 array on a 280x55mm substrate. There is a connector (from Molex), at each end of the board. nominal drive is 300mA. Mounting is by screws.
