With a 120° Viewing Angle, 330 Lumen OutputCARROLLTON, Texas, Feb. 22, 2006 -- Combining high-brightness LEDs with
three-dimensional packaging technology, TT electronics' Optek
Technology has introduced what the company describes as one of the
industry’s brightest single-source packaged visible LED assemblies.
Designated the Optek Lednium series, the 10-W package offers a full
120° viewing angle for its array of amber, blue, green, red or white
Optek Technology manufactures standard and application-specific
sensors using infrared, visible, magnetic and fiber optic technologies
focused on applications in office machines, industrial equipment,
encoders, automotive electronics, military applications and medical
diagnostic equipment. Last year Optek signed a joint agreement with
Lednium, an Australian LED technology company, to develop a series of
solid-state lighting products using Lednium’s packaging technology.

Unit, the Lednium series devices achieve an output of up to 330 lumens
with nine 1-W LEDs mounted in an anodized aluminum package just 1.3 in.
square, with a board-mounted profile of less than half an inch. “The
ability to put high-brightness LEDs in a compact, energy efficient
package will have significant impact on the lighting industry,” Saffa
explained. “As one of the brightest single-source LED assemblies
available today, Optek’s Lednium series devices have the potential to
make solid-state lighting a practical reality for a wide range of
Conventionally-packaged LED arrays with comparable light output
often require as many as 12 1-W LEDs in configurations up to 8 in. in
diameter, which typically consume more power. The wide viewing angle
and increased brightness are critical features for lighting design
engineers as they begin to incorporate solid-state light sources into
applications such as automotive interior and exterior lighting, indoor
and outdoor electronic signage and displays, as well as architectural
lighting and general lighting applications.
The Optek Lednium LED assemblies also provide different
parallel-serial connections that enable the operation of three, six or
all nine of the mounted LEDs, enabling design engineers to vary the
light output and power consumption.
Lednium series devices are available in amber (595 nm, 330 lm);
blue (467 nm, 60 lm); green (524 nm, 290 lm); red (624 nm, 247 lm); and
white (250 lm). All colors feature a full 120° viewing angle in
water-clear lenses. In development are other visible, as well as
ultraviolet and infrared wavelengths and package configurations.
DC forward current is 1.05 A, with peak pulsed forward current
of 3 A. Typical forward voltage characteristics range from 6.3 V to
9.25 V (color-dependent), and reverse voltage for all devices is 15 V.
Maximum allowable junction temperature is 130 °C (average thermal
resistance junction-to-board is 5 °C/W), and the operating temperature
range for the device is -50 to +80 °C.
The Lednium series is stocked by Optek’s distributors in the
Americas, Europe and Asia. Production quantity lead times are from
stock to six weeks. For more information, visit: www.optekinc.com/led_pr1.asp; e-mail: firstname.lastname@example.org
