LED Market Headed for 20 Billion Units in the Coming Year
Market will see higher light-emitting efficiency and lower cost
Design News Staff -- Design News, October 6, 2008
The market for LEDs is growing larger as they go into more products and those products head for high volume sales. There are five primary markets for LEDs: handheld applications such as mobile phone handsets and digital cameras, medium-size applications that include ultra-mobile PCs and small digital photo frames, large-size applications such as billboards, marquees and LCD TVs, automotive applications that include indicator and illumination lighting and general illumination such as general indoor and outdoor lighting. We'll soon see the proliferation of LED headlamps on cars, as well as LEDs in auto interior lighting. LEDs will increasingly be used for general illumination applications around 2013 and 2014.
HIGH-EFFICIENCY ULTRAVIOLET LED SERIES
Bivar Inc. has announced the addition of the UVTZ series of high-efficiency ultraviolet (UV) LEDs. The new UV LEDs are available in 3 mm (UV3TZ) and 5 mm (UV5TZ) through-hole packages each comprised of four tightly binned wavelengths, 390, 395, 400 and 405, with a wavelength tolerance of ±2.5 mm. According to Bivar, the new UVTZ series provides 10-20 mW output while consuming only 15 ma of current, with a rated operational life of 10,000 hours compared with 1,000 to 2,000 hours of many other available devices. Both packages are available with a narrow 15 degree and slightly wider 30 degree viewing angle. Each LED contains an integrated zener diode to provide enhanced ESD protection. The LEDs are built for high resistance to shock and vibration compared with filament-based light sources.
YELLOW AND AMBER LEDS BUILT FOR THERMAL RESISTANCE AND HIGH OPTICAL POWER
Vishay Intertechnology Inc. has released a series of high-intensity amber and yellow power LEDs in a CLCC-2 flat ceramic package with driving currents up to 4,000 mA. The light-efficient VLMK82 and VLMY82 devices were designed to offer low thermal resistance of 20 K/W and high optical power of 5,600 mcd to 14,000 mcd for thermal-sensitive applications. With the ultra-low profile of only 0.75 mm, the CLCC-2 flat ceramic package of these LEDs were built to allow the additional current drive for a maximum light output while maintaining a high service life of up to 50,000 hours, making them appropriate light sources in space-limited applications where thermal management is a key consideration. Samples and production quantities of the new LEDs are available now, with lead times of eight weeks for large orders.
