Seoul flash LEDs compete with Xenon for digital cameras
Seoul Semiconductor has launched a new flash LED product that can be driven at up to 2 A, providing sufficient light output for high-quality flash.
The company says that its Flash LEDs are to be used by a global digital camera manufacturer to provide flash capability in its digital still cameras. No further details are available.
Seoul Semiconductor's new flash LED, the FCW211Z series, features high brightness, ultra-miniature size, and long lifespan.
FCW211Z can operate at a current of 2 A, and emit up to 100 candelas, which Seoul says is more than twice the brightness level of conventional LEDs for flash.
The Flash LED's small size supports the miniaturization of devices, and is suitable for ultra-small products such as mobile phones, digital cameras and video cameras.
The FCW211Z Series measures 3.5 x 3.0 mm, with a height of 0.75 mm. In comparison, a Xenon lamp for a mobile phone typically measures 10.1 x 4.6 mm, with a height of 3.5 mm.
Seoul says its FCW211Z series enables the capture of moving images and continuous shooting without a need of charge while conventional xenon lamps are not available for those functions.
Furthermore, the LEDs offer more than two times longer lifespan than conventional xenon lamp.
"The performance of conventional LEDs were not the best for flash due to its poor brightness despite its availability in moving image, ultra-mini size, and long lifespan. However, with our new FCW211Z series, we can now enjoy both the advantages of LEDs and superior image quality with brightness that is comparable to xenon lamp," says Byung Hack Lee, head of the chip and module business division at Seoul Semiconductor.
