Controlling LEDs Part 4 - Five questions when trying to dim an LED product?

Before you commit yourself or your customer to investing in LED technology you need to understand its limitations, especially when it comes to dimming control compatibility. Many LED luminaire manufacturers are new to the lighting industry and are not familiar with the multitude of control types and the corresponding product design requirements that accompany them. This has resulted in “dimmable” products that do not work as claimed,...

Controlling LEDs Part 3 - Why Dim LEDs?

Similar to fluorescent, incandescent and other conventional light sources, dimming LEDs saves energy at a roughly 1:1 ratio. This means that if you dim LEDs down to 50% of their light output you will save nearly 50% of your energy usage. So not only do you save by using a more efficient source, you save even more energy by dimming LEDs. Dimming LEDs also makes them run cooler, which should extend the life of the electronic components...

Controlling LEDs Part 2 - Advantages and Limitations of LEDs for General Illumination

LEDs Advantages for General Illumination High Efficacy (Lumens per Watt) LED-based lighting fixtures can achieve efficacies ranging from 25 LPW to over 80 LPW, compared to an incandescent efficacy of 5-10 LPW. Longevity LEDs can achieve useful lifetimes ranging from 25,000 hours to up to 100,000 hours, compared to ~1000 hours for an incandescent.  LEDs do not contain hazardous materials as compared to mercury vapor in CFLi bulbs. LEDs...

THE MUTED VOICE OF LIGHTING DESIGNERS BY JAMES BEDELL

There is little question that lighting has a direct impact on energy consumption. There is also little argument that lighting fundamentally changes a space. Lighting is elemental to how we live and the spaces we occupy everyday. The rules of the game and the expectations for what light does are changing rapidly. By now everyone has heard that the future of lighting will be the LED and most educated consumers understand that the end is near for the...
