Red and Amber Lamps with 15°/30° Viewing Angle
SAN JOSE, Calif., and SINGAPORE, June 21, 2010
Avago Technologies (Nasdaq: AVGO), a leading supplier of analog interface components for communications, industrial and consumer applications, today announced its support of European Standard EN 12966-1 for variable message traffic signs with new 5mm extra high brightness LED lamps.
Avago’s new LED products to support the variable message traffic sign requirements for 15° and 30° viewing angles are the HLMP-Ex1A/1B-xxxDV (15°) and HLMP-Ex3A/3B-xxxDV (30°). These 5 mm extra bright LEDs have minimum luminous intensity ratings of 12,000 mcd (15° LEDs) and 5,500 mcd (30° LEDs) and are available in red and amber colors.
The visual requirements of signs set the viewing angle of the LEDs. Signs installed on highways, for example, require bright LEDs with a narrow beam width, but in cities with a requirement for short distance legibility a wide beam width LED is usually required.
Outdoor message signs must typically operate for over ten years in a harsh, corrosive, and exposed working environment. Avago’s new 15 and 30 degree viewing angle lamps are manufactured for outdoor signal and sign applications. The maximum LED junction temperature limit of +130° C enables high temperature operation in bright sunlight conditions. The lamp epoxy uses UV inhibitors to reduce the effects of long term exposure to direct sunlight.
Applications for LED lamps in road equipment and signage include:
– Traffic management
– Traffic signals
– Pedestrian signals
– Work zone warning lights
– Variable message signs
– Solar powered signs
– Commercial outdoor advertising
The new 15° and 30 ° viewing angle LED lamps, which are available now for production orders, are lead-free and RoHS-6 compliant.
