The measurement of light can be separated into a range of measurement principles. Each of these measurement principles is quantified according to different optical parameters. In the case of ...

This file type includes high resolution graphics and schematics. LEDs are the most efficient way to turn an electric current into illumination. When a current flows through a diode in the forward ...

A family of high-intensity low-current, single-digit, seven-segment displays that provide excellent readability even in direct sunlight was announced by Vishay Intertechnology. The Vishay ...

Designed to measure LED luminosity from the near UV to the near IR, the IL1400A portable radiometer and LED probe verifies the output of LEDs, traceable to NIST standards. The instrument provides ...

Unlike incandescent tungsten-filament light bulbs, high-power LEDs do not radiate heat. Instead, LEDs conduct heat from their PN junction to the thermal slug on the LED package. Because the heat ...
