LED COMPARISONS

  LED (or Light Emitting Diode) lighting products are quickly taking over the incandescent lamp world.  They are meeting the needs of the present, without compromising the generation of the future’s own needs.  LED lamps use up to 75% less energy than incandescent lamps, without the production of carcinogenic materials (such as lead and mercury) [...]

LED AND THE ENVIRONMENT

LED AND THE ENVIRONMENT

  Tests conducted at the University of California-Davis and Irvine, on LED traffic lights, automobile headlights, brake lights and Christmas tree lights, showed unsafe levels of some toxins.  After LEDs were crushed, they were found to contain lead, arsenic, nickel and other hazardous substances.  Their conclusions may put a damper on the growing popularity of [...]

LED, ORGANIC LIGHT

LED, ORGANIC LIGHT

  THE BIRTH OF OLEDs: Organic Light-Emitting Diodes, or OLEDs, were invented by Dr. Ching Tang at Eastman Kodak.  Although this took place in the late 1970’s, it is just now (over two decades later) finding its way into markets.  It was confined to cell phones and small video displays for years, now it is [...]

LED, WHAT IS IT?

Light Emitting Diode (LED) is a semiconductor light-producing unit.  When an electrical current passes through the unique materials, there is a recombination of positive and negative charges resulting in the emission of photons, as light energy.  This action is called electroluminescence.  The color of the light is determined by the energy gap of semiconductor and [...]
