OSRAM Opto Semiconductors Inc. today announced the newest members of its leading light-emitting diode (LED) product family: OSLUX(TM) and CERAMOS(TM) "super-bright" LEDs that are ideal for "flash light" applications in mobile communication devices such as phones and digital cameras.
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, as in mobile phones, and where high luminous intensity is still needed.
"OSRAM is delighted to announce these innovative advancements to our LED product portfolio," said Ellen Sizemore, North American director, LED and IR Products Group, OSRAM Opto Semiconductors. "Both new solutions provide our customers with the desirable combination of extremely high levels of brightness with low power consumption, and their rapid flash frequencies enable even small mobile terminals to be suitable for short flash sequences or a complete series of pictures," she added.
OSLUX
The compact and efficient OSLUX boasts an aspherical lens and a luminous efficacy of 48 lumens-per-watt (lm/W), providing homogeneous light right into the photo margins at a distance of one-to-three meters (m). Illumination is optimized for rectangular photos and, in a direct target area of 1.15 x .87 m, achieves more than 50 Lux (lx). With OSLUX, the superior thermal properties of the LEDs, combined with short switching times and high-output operation, enable rapid flash frequencies to be achieved with peak currents of 1500 mA.
CERAMOS
OSRAM's CERAMOS LED device can be combined with various proprietary and/or customer-specific lenses for greater flexibility. These applications include mobile phones, where both versatility and high luminous intensity is necessary. The lumen values correspond to those of the OSLUX, and the specific lens determines the Lux value. With low thermal resistance and short switching times, CERAMOS can handle higher than normal currents (1000 mA) and flash rapidly in succession.
The two new LED products are based on a 1-millimeter2 (mm) chip using indium gallium nitride (ThinGaN(R)) technology, and can be operated either in pulse mode or with a constant current. The technology allows highest brightness levels at lowest operating voltage, is scalable and supports all wavelengths.
Both new devices offer the advantages of OSRAM's surface-mount technology (SMT), enabling lower-profile, low-cost solutions to be produced. The SMT package allows the OSLUX and CERAMOS to be processed using standard automated placement and solder techniques, reducing assembly costs. Both products operate at peak currents of 1500 milliamps (mA, OSLUX) and 1000 miliamps (mA, CERAMOS) respectively and can be handled in SMT solder processes at up to 260 C.
