New High-Current LED from OSRAM Boosts Brightness for Small Projectors with No Increase in Size



New generation of OSTAR Compact LED provides more light output

Sunnyvale, CA - The new OSTAR Compact LED from OSRAM Opto Semiconductors is characterized by improved high-current capability and lower thermal resistance for more light output. It can handle up to 6A in pulsed mode, making it ideal for pico and pocket projectors for small mobile terminals.

The new OSTAR Compact is accommodated in the same 3.9 mm x 3.6 mm 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, 600 lm in green and 165 lm in blue in pulsed mode (typically 120 Hz, 2 ms, Ts= 25°C). Thanks to a new packaging material, its thermal resistance has been reduced to 3 K/W, compared to 6 K/W for the previous version, allowing heat to be dissipated more efficiently.

The enhanced 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 distribution. "This has enabled us to design the OSTAR Compact LED for even higher current handling capacity," said Wolfgang Schnabel, Marketing Manager, Projection, at OSRAM Opto Semiconductors. "The new version offers higher luminous power for smaller projector designs. The OSTAR Compact is small, but delivers increased brightness with its advanced thermal management design."

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 µm x 750 µm and 1 mm x 1 mm available in all colors.
