Reflector LED creates brighter
backlights
Devices are ideal for light-guide-based backlighting of displays in high ambient light conditions, such as in automotive dashboards and aircraft cockpits.
Osram Opto Semiconductors reckons its new Ceramos reflector LED provides unprecedented high brightness and power in a very small package, making it the ideal solution for backlighting mid-size (5-20in) LCDs Specifically designed for light-guide-based backlighting of displays in high ambient light conditions, such as those found in today's TFT displays, automotive dashboards and aircraft cockpits, the slim profile of the Ceramos reflector LED is well suited for icoupling into light guides as thin as 2mm

Super-bright LED keeps its cool
The exceptionally low thermal resistance of the Diamond Dragon's SMT package allows heat produced in the chip to be efficiently removed from the LED.
OLED tile promises lighting efficiency
OLED prototype has achieved a luminous efficiency of more than 20 lumen/W at a brightness of 1000cd/m.
This feature also makes the LED ideal for edge lighting for LCD TVs and monitors.
The Ceramos reflector LED is powered by Osram's patented ThinGaN LED technology, which enables it to operate at a high level of optical efficiency - 70 lumen/W at 80mA.
Ceramos delivers a long life of 50kh, and its SMD ceramic package enables excellent performance at high operating temperatures (up to 150C), and is compatible with standard surface mount processes.
The slim, compact package dimensions (2.3 x 3.2 x 0.8mm) facilitate integration into small display designs, and the oval out-coupling window allows for use in thinner light guides.
Mercury-free and RoHS-compliant, the new Ceramos reflector LED is the perfect solution for light guide backlighting.
"As more display manufacturers look for an eco-friendly alternative to CCFL backlighting, the Ceramos reflector LED offers excellent efficiencies in brightness, lifetime and power savings in a compact package ideally suited for back lighting applications", says Ellen Sisemore, Director, LED/IR Marketing, Osram Opto Semiconductors.
In addition to display backlighting, the Ceramos reflector LED can be used for camera flash and strobe lighting; reading lamps in aircraft, cars and buses; decorative and entertainment lighting; and signage or marker lights.
