Avago oval LEDs raise the bar for viewing full-colour displays
The company says its latest through-hole indium gallium nitride and phosphide LED series reduce power consumption and provide consistent light from all angles.
Supplier of analogue interface components for communications, industrial and consumer applications, Avago Technologies, has released three series of high-brightness oval through-hole LEDs.
The new red AlInGaP LEDs are available at 626-nm dominant wavelength, and the new green InGaN and blue InGaN LEDs are available at 530-nm and 470-nm, respectively. The maximum luminous intensity at 20 mA of the new LEDs is as follows (measured in millicandelas):
* 4 mm standard oval HLMP-Lx75 LEDs: Red – 2400, Green – 6050 and Blue – 1660
* 5 mm standard oval HLMP-Hx74/75 LEDs: Red – 2400, Green – 6050 and Blue – 1380
* 5 mm mini oval HLMP-Ax74/75 LEDs: Red – 4200, Green – 7260 and Blue – 1990
Additional HLMP-Lx75, HLMP-Hx74/75 and HLMP-Ax74/75 Features
* Standoff packages for all series and non-standoff packages for HLMP-Hx74/75 and HLMP-Ax74/75 LEDs
* Lead-Free and RoHS 6 compliant
* Tinted and diffused
* Operating temperature range of -40° to +100° C for red LEDs and -40° to +85° C for green and blue LEDs
* Electro-static discharge sensitivity: JEDEC Class 1C HBM
Avago says that they have set a new performance standard for electronic signage applications. The new HLMP-Lx75, HLMP-Hx74/75 and HLMP-Ax74/75 LEDs deliver industry-leading brightness for oval through-hole LEDs, reducing the current required to drive systems.
The LEDs’ matched RGB radiation pattern is designed to maintain consistent light and uniform colour mixing from all viewing angles. This combination enables sharper viewing quality with lower power consumption for full-colour signage such as billboards, stadium video screens, building video walls, as well as for simpler roadway and commercial signage.
The HLMP-Lx75 and HLMP-Hx74/75 LED series offer a typical viewing angle of 40 by 100 degrees, while the HLMP-Ax74/75 LEDs offer 30 by 70 degrees. The wide typical viewing angles and the high luminous intensity of the LEDs deliver optimal performance for outdoor applications.
The package epoxy of the LEDs contain UV inhibitors to reduce the effects of long-term exposure to direct sunlight, and also offer superior resistance to moisture, providing enhanced durability for outdoor environments. Avago provides design flexibility with the option of shipping tight colour and intensity bins, up to 4 nm per bin for the new blue and green LEDs.
“Our customers already recognise the quality Avago LEDs bring to full-colour electronic signage applications, and we believe these new offerings will add to our reputation and success in this quickly growing market,” said Francis Khor, director of marketing for the optoelectronics products at Avago. “These efficient and durable new LEDs provide superior viewing performance, along with cost savings realised from lower power consumption and reduced maintenance.”
