TORRANCE, CA — July 28, 1999 — Continuing to expand the LED universe, LEDtronics® announces today the availability of new Crescent
Bargraph LEDs. Featuring 15 LEDs arranged in a graceful semi-circle, Crescent Bargraph
LEDs add visual appeal to mundane displays such as temperature gauges, automotive
instrument panels, volume levels, ultraviolet meters, audio/video indicators,
etc. . . .
Crescent Bargraphs LEDs operate between 565 – 660 nanometers
(Ultra-Red = 660, High-Efficiency Red = 635, Yellow = 585, High-Efficiency
Green = 565) at 10mA. These compact bargraph LEDs are available in any Red,
Green Yellow color combination with brightness characteristics ranging from
4.5 – 8.0 typical mcd at 25° C depending on the color of the LED.
For each LED in the package, there is a single common contact point for
negative (Cathode) and one contact point for each LED positive (Anode) for
a total of 16 leads.
Crescent Bargraph assemblies may be configured with LEDs of a single color
or with LEDs of several colors. Standard colors available are Ultra-Red,
High-Efficiency Red, Yellow and High-Efficiency Green, but custom colors
(Orange, Pure Green and Blue) that may better complement your design may
be ordered. All colors are sunlight visible. Lenses are diffused. Also,
the segment color is white when powered off. These multi-colored LED bargraphs
enable the integration of low powered, evenly diffused, compact module displays
into user interfaces.
Solid-state design renders Crescent LED Bargraphs impervious to electrical
and mechanical shock, vibration, frequent switching and environmental extremes.
Crescent LED Bargraphs are excellent choices for a wide range of display,
fault or status indicators that require easy-to-read measurements such as
readouts that indicate low, safe and overfilled conditions. With an average
life span of 100,000-plus hours (11 years), Crescent LED Bargraph displays
operate reliably year after year. That’s more than 10-20 times longer
than incandescent bulbs! Additionally, Crescent LED Bargraphs are environmentally
friendly because they use 80% to 90% less operating power than standard
incandescent bulbs. Think of the savings from reduced power usage, maintenance
costs and less downtime!
Founded in 1983, LEDtronics® leads where others only follow when it comes
to designing, manufacturing and packaging state-of-the-art LEDs to meet
the world’s constantly changing lighting needs. Our inventive product
line encompasses an array of direct incandescent lamp replacement Based
LEDs, low-cost snap-in and relampable Panel Mount LEDs, high intensity sunlight-visible
Discrete LEDs, PCB LEDs circuit board status indicators, surface mount diodes
SMT LEDs, full-spectrum rainbow RGB LEDs and Infra-Red (IR) LEDs.
Prices for Crescent LED Bargraphs range from $8.25 each - $3.03 to $2.86
in quantity of 1,000 depending on the choice of LED color and LED technology
level. Crescent LED Bargraphs are custom molded. Standard Crescent LED Bargraphs
are available as samples to meet your design requirements for qualified
customers. For a additional information on how to incorporate the Crescent
LED Bargraphs into your display applications, contact LEDtronics toll free
