High bright RGB LEDs from Avago for signage
applications
Avago Technologies has announced 3 series of high-brightness
oval through-hole LEDs HLMP-Lx75, HLMP-Hx74/75 and HLMP-Ax74/75
reducing the current required to drive systems.
Avago explains that the LEDs' matched RGB radiation pattern
is designed to maintain consistent light and uniform color
mixing from all viewing angles. This combination enables
sharper viewing quality with lower power consumption for
full-color signage such as billboards, stadium video screens,
building video walls, as well as for simpler roadway and
commercial signage.
Avago describes HLMP-Lx75 and HLMP-Hx74/75 LED series as
it provides a typical viewing angle of 40 by 100 degrees,
while the HLMP-Ax74/75 LEDs offer 30 by 70 degrees. The
package epoxy of the LEDs contains UV inhibitor to reduce
the effects of long-term exposure to direct sunlight, and
the package also offer superior resistance to moisture,
providing enhanced durability for outdoor environments.
Additional features of the series includes:
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
"Our customers already recognize the quality Avago
LEDs bring to full-color 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 realized
from lower power consumption and reduced maintenance."
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
Availability: Now in samples and production quantities.
Price: $0.21 each for 2K units of green and blue,
$0.12 each for 2K units of red
