LUXEON Flip Chip
Chip Scale Package LED
Introduction
Philips Lumileds LUXEON
®
Flip Chip LED Technology enables the next generation of lighting applications.
Customers now have complete design flexibility to access Lumileds’ industry leading performance at the die level
and customize the phosphor and packaging to best suit their lighting applications.
LUXEON Flip Chip is a real Chip Scale Package LED that can be attached by reflow without additional packaging.
Traditional wire bonding limits the packing and power density of LEDs. LUXEON Flip Chip LEDs can be packaged
closer and can be driven at a higher current density, therefore requiring fewer emitters to achieve a higher lumen
output at higher lumen densities.
This document contains the performance data needed to design and engineer Philips Lumileds LUXEON Flip Chip
based application.

Notes for Table 4:
1. Proper current de-rating must be observed to maintain the junction temperature below the specified maximum junction temperature.
2. Residual periodic variations due to power conversion from alternating current (AC) to direct current (DC), also called “ripple”, with frequencies
≥
100Hz and amplitude
≤
250 mA are acceptable, assuming the average current throughout each cycle does not exceed the specified maximum DC forward current and the junction temperature is
kept below the specified maximum junction temperature.
3. Pulsed operation with a peak drive current of 1300 mA is acceptable if the pulse on-time is
≤
5ms per cycle and the duty cycle is
≤
50%.
4. Please see the LUXEON Flip Chip application brief for additional information on ESD protection.
