Benefits of Solid State Lighting vs. Conventional Lighting
Lasts longer than any other light source - 10,000 hours, reduced maintenance costs, more energy efficient - environmentally friendly, no heat or UV in the light beam ... read more
what is light emitting diodes
A light-emitting diode (LED) is a semiconductor device that emits incoherent narrow-spectrum light when electrically biased in the forward direction. This effect is a form of electroluminescence. ... read more
leds failure modes
The most common way for LEDs (and diode lasers) to fail is the gradual lowering of light output and loss of efficiency. However, sudden failures can occur as well. ... read more
Considerations of using leds
Unlike incandescent light bulbs, which light up regardless of the electrical polarity, LEDs will only light with positive electrical polarity. When the voltage across the p-n junction is in the correct direction, a significant current flows and the device is said to be forward-biased. ... read more
Advantages and disadvantages of using LEDs
LEDs produce more light per Watt than do incandescent bulbs; this is useful in battery powered devices. ... read more
light emitting diode driver considerations
Many of today's portable electronics require backlight LED-driver solutions with the following features: direct control of current, high efficiency, PWM dimming, overvoltage protection, load disconnect, small size, and ease of use. ... read more
