LEDs boost electronic-signage viewing quality

Avago Technologies has launched three series of high-brightness oval through-hole LEDs for electronic signage applications.

Dubbed HLMP-Lx75, HLMP-Hx74/75 and HLMP-Ax74/75, these LEDs reduce the current required to drive systems. The LEDs' matched RGB radiation pattern is designed to maintain consistent light and uniform color mixing from all viewing angles.

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 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

Pricing: The green and blue HLMP-Lx75, HLMP-Hx74/75 and HLMP-Ax74/75 LEDs are priced at $0.21 each in minimum quantities of 2,000 pieces, and the red LEDs are priced at $0.12 each in minimum quantities of 2,000 pieces.

Availability: Samples and production quantities are available now through the Avago direct sales channel and via worldwide distribution partners.
