  • Reliability Of LEDs
    As mentioned earlier, the luminous intensity of LED lamps characteristically declines slowly with use. Select LED lamps according to the level of reliability require in the equipment in which they will be used.
  • Measurement of LEDs
    If there were ever any question that LEDs would be such a dominating lighting technology just take a look around. They are virtually everywhere. From standard indicators on stereo equipment, laptops and toys to traffic lights, variable message signs and automotive lighting, LEDs have enjoyed
  • Derating LEDs
    Toshiba technical data for LED lamp usually shows the permissible current values against temperature. Refer to this information when planning a new design.
  • LED Measurements
    Since it is possible to manufacture Light Emitting Diodes in a wide variety of colors and brightness, it is also necessary to accurately measure their optical characteristics. There are two ways of measuring LED's, photometry and radiometry. Photometry only relates to visible radiation, like
  • LED Active Cooling Solutions
    With more and more LEDs being used in the world active cooling of the LEDs is needed to preserve the life of the LEDs.
  • Power Supplies for LED Driving
    Power Supplies for LED Driving. Including detailed examples of what works and why, this practical, hands-on book covers the design trade-offs involved in LED driving applications, from low-power to UB-LEDs and beyond.
  • What is an LED Light Pipe?
    An LED Light Pipe is a practical solution to conduct light from board-mounted LED(s) to the exterior, or in some cases, a photodetector.
  • Design of Fundamental LED Circuits
    The IR LED emitter is commonly continuously powered, forcing a constant DC current through the LED. The LED is connected to the DC supply via current limiting resistor. Equation included in piece.
