![]() For low cost applications a pure blue/white LED approach might be preferred, but the market is currently also asking for higher CRI values. The decay in lumen output is less than 5% and the color shift is negligible. The Department of Energy in the United States, is continuously testing former blue/red chip bulbs and they are still running after 40,000 hours. You need to control both channels because the two materials have different temperature characteristics. Lee: The blue/white LEDs plus the red chip still give you the highest performance but you need two channel controls. LED professional: What about Epistar’s high-voltage LEDs with a combination of blue and red LED chips?ĭr. In the future for micro-LED and smart, digital lighting you may need RGB mixing to support this market. Backlighting and solid-state lighting need blue LEDs. ![]() Lee: Currently, of course we still focus mostly on visible light. LED professional: What are the main markets that you address?ĭr. We endeavor to cover the full spectrum range, infrared, visible and UV technologies. We are trying to bring the so-called “one-stop shopping” to our customers. Our products range from the red, yellow, orange, green and blue - all the visible range - and lately also included some of the infrared and ultra violet. ![]() Since then we have also started to focus on different wavelengths of LED chips. Right from the beginning we positioned ourselves as a pure chipmaker. LED professional: Could you give us a short overview of Epistar’s strategy and positioning within the LED business?ĭr. ![]()
