AXT, Inc. Announces Breakthrough in Large, High Flux LED Chips
AXT, Inc. a leading manufacturer of opto-electronic devices and compound semiconductor substrates, today announced the introduction of production quantities of large, high flux aluminum indium gallium nitride (AlInGaN) chips in green, cyan and blue. The P2 chips, which are much larger than standard sized LED chips, are designed for applications, such as automotive lighting, dental curing and general illumination that require the maximum luminous flux per device.
The green P2 chips have output powers (at 350 milliamps) up to 27 milliwatts with 17.5 lumens per watt efficiency. The cyan P2 chips, designed for use in traffic signals, have output powers of 30 milliwatts with 12.5 lumens per watt. The new blue AlInGaN-based LEDs have output powers up to 35 milliwatts and achieve efficiencies of 6 lumens per watt.
``The introduction of our P2 chip is another example of how AXT is becoming a leading player in the LED industry, said Morris Young, president and chief executive officer ``Only a handful of companies have experienced this level of luminous flux in an AlInGaN chip. We expect further improvements in our large chip performance in the near-term as we continue to invest in advancing our technology.
Brightness Increases 30 Percent Over Previous Generation Product
AXT have also made significant brightness improvements in production quantities of green, cyan and blue light emitting diode (LED) products. The brighter LEDs have 30 percent more power than the company s previous generation LEDs and allow AXT to compete with the top-tier players in the LED industry. AXT s chips are already being purchased by many of the world s largest LED packagers because of their reputation for high reliability, and the brightness improvements will increase AXT s competitiveness in the large and rapidly growing video display, traffic signal and backlighting markets.
The new green, cyan and blue aluminum indium gallium nitride (AlInGaN)-based high brightness LEDs have typical output powers (at 20 milliamps) of 2.0 milliwatts, 2.2 milliwatts, and 3.0 milliwatts, respectively. The expected packaged lamp power output for these devices is 4.0 milliwatts, 4.4 milliwatts, and 6.0 milliwatts.
``I am pleased with our continued progress in improving our brightness levels across all colors of our AlInGaN devices, said Morris Young, president and chief executive officer. ``This accomplishment is even more impressive given that it has occurred simultaneously with a major ramp up in our LED production. We expect further brightness improvements in the near-term as we continue to invest in advancing our technology.
