RGB LED achieves
1,725-mcd output
http://www.electronicproducts.com/ShowPage.asp?SECTION=3130&PRIMID=&FileName=marHL4.mar2003
White-output device's 6-pin package enables
each color to be driven independently
Designed as a light source for 3G phone cameras
and display backlights, the GM5WA06260A TAF
Series RGB three-die chip LED delivers white
light with a luminous intensity of up to 1,725
mcd. The device's 2.4-mm-thick 6-pin package
enables it to be connected in series while
allowing each color to be driven independently.
The GM5WA06260A TAF Series RGB three-die chip
LED delivers white light with a luminous
intensity of up to 1,725 mcd.
In addition to providing a design alternative to
single-die white LEDs, the independent color
control enables improved control over heat output
and color balance. Typical red, green, and blue
forward voltage and current are 2.3 V at up to 40
mA; 4.4 V at up to 40 mA; and 4.6 V at up to 20
mA, respectively.
The LED's operating temperature ranges from
–30° to +85°C. (From $2 ea/5,000--available now.)

Look out, Las Vegas: LEDs are coming after your neons!

Offering alternatives to neon and incandescent signage-light sources, Light Stix LEDs from the Sunbrite Group of Lumex feature brightness, easy installation, long life, and low power (Picture). A typical Light Stix uses 36 LED chips, yielding a total light intensity of 400 cd/m2 over a 60° viewing area. Power consumption is 3W at 24V dc, and lifetime is 100,000 hours over 11 years of constant use.
Unlike glass-enclosed neon lights, these lights come in easy-to-mount plastic tubes with one side flat and with integral mounting brackets. You can mount these 600-mm (24 in.)-long, 34-mm (1.3-in.)-diameter lights end to end to extend their length. They are available in red, yellow, green, blue, and white, and prices begin at $50, depending on color and quantity.

Blue LED breaks
size, power barriers
http://www.electronicproducts.com/ShowPage.asp?SECTION=3130&PRIMID=&FileName=marHL1.mar2003
High-efficiency device has a brightness of 100
mcd
Presented as the first device to use
nanotechnology in the fabrication process, the
CyberLite blue LED requires less than 2.9 V at 20
mA for a brightness of 100 mcd. Smaller than a
grain of sand, the device can be combined with a
yellow phosphor to create a white LED, promising
to speed the implementation of solid-state
lighting in a wider variety of applications.
The CyberLite blue LED chips require less than
2.9 V at 20 mA for a brightness of 100 mcd.
The LED's light-emitting nano-structures, called
NanoPockets, are created in a manufacturing
process that also reduces material defects. An
additional advantage of the process is that the
LED has an ESD resistance of over 4,000 V, up to
twice that of standard LEDs. (From less than $0.50 ea/large qty --available now.)
