The LED can
be used wherever there are large fluctuations in temperature and a large amount
of light is needed from a small area. The thermal coefficient of expansion
of the molding material precisely matches the coefficient of expansion of the boards,
and there is an ESD protective diode concealed in the molding. The high output
efficiency in the black package does not require additional reflectors. The
materials have been chosen so that even large fluctuations in temperature do
not have an adverse effect on reliability or on the life of the LED (approx.
50,000 hours). The Oslon LED
has a low thermal resistance of 6.5 K/W.
The Oslon Black Series has a lens with
a 90 degree beam angle and produces a typical brightness of 115 lm at an operating
current of 350 mA and a color temperature of 6500 K. By increasing the operating
current to 1 A, it is able to achieve a brightness of 250 lm. The LED uses a 1 mmÂ²
chip and is available in all colors, including warm white. The Oslon Black Series solder pad is
compatible with the other LEDs in the Oslon product family.
The LED is useful for signal lights, interior
lighting for refrigerators and lighting for train, planes, automobiles, and
The fun factor continues to draw developers to Linux. This open-source system continues to succeed in the market and in the hearts and minds of developers. Design News will delve into this territory with next week's Continuing Education Class titled, “Introduction to Linux Device Drivers.”
