The new OSTAR Compact LED from OSRAM Opto Semiconductors is accommodated in the same 3.9 x 3.6mm
package size as the previous version, enabling small projectors to be designed
with higher brightness without increasing their size. Instead of 4A, the new
LED can now be pulsed up to 6A, achieving 350 lm in amber, 600lm in green and
165 lm in blue in pulsed mode (typically 120Hz, 2 ms, Ts= 25C).
Thanks to a new packaging material, its thermal resistance has been reduced to
3K/W, compared to 6K/W for the previous version, allowing heat to be dissipated
performance of the high-power OSTAR Compact LED is achieved with a 2 mm² chip
that benefits from improved epitaxial processes and a more even power
The new LED with the higher current capability extends
the portfolio of OSTAR Compact LEDs for projection applications. The OSTAR
portfolio includes LEDs with chips having sizes of 750 x 750µm and 1 x 1mm
available in all colors.
