Osram Opto Semiconductors has developed two super-bright LEDs especially for flash light. OSLUX has beam characteristics that are ideal for photo formats and homogeneous brightness right into the margins.

CERAMOS can be combined with various lenses and offers great versatility for applications in which space is at a premium, for example in mobile phones, but high luminous intensity is still needed.

OSLUX
The compact and efficient OSLUX with its aspherical lens and a luminous efficacy of 48 lm/W provides homogeneous light right into the margins at a distance of 1 to 3 m. Illumination is optimised for rectangular photos. In the direct target area of 1.15 x 0.87 m it achieves more than 50 lx.

The good thermal properties of the LEDs, combined with short switching times, enable rapid flash frequencies to be achieved and high-output operation with peak currents of 1500 mA. The LED and lens can be handled in standard SMT solder processes at temperatures up to 260°C.

CERAMOS
CERAMOS is another flash light LED. It offers impressive versatility and high efficiency. It can be combined with various proprietary and customer-specific lenses.

The lumen values correspond to those of the OSLUX; lux values depend on the lens used. With a low thermal resistance and short switching times, this LED can handle higher than normal currents and flash rapidly in succession.

The two LEDs are based on a 1 mm2 ThinGaN chip and can be oper-ated either in pulse mode or with a constant current. They provide high levels of brightness for low power consumption. Their rapid flash frequencies make even small mobile terminals fit for short flash sequences or complete series of pictures.
