Bright Future for Plating LED Lights
LEDs are widely used in the electronics and automotive industries, together with household and road lighting applications. Silver plating of the LED substrate can be carried out via conventional rack or reel-to-reel plating procedures.

Most industrial nations have gradually removed incandescent light bulbs from the market due to their inadequate performance and high consumption of electricity.
In 2008, the European Union began the process, and in 2012, the last incandescent bulb was sold and the rest removed from the shelves the following day—marking the end of a technology era that had caused a revolution when it was introduced about 130 years ago.
The U.S. Congress passed a law in 2007 to begin phasing out the old familiar tungsten-filament 40- and 60-watt incandescent light bulbs by the beginning of 2014.
Light emitting diode (LED) technology provides an efficient alternative to standard bulb technologies. The efficiency of each lamp type can be expressed as “luminous efficacy,” defined as the ratio of the luminous flux emitted from the lamp per electrical power required by the lamp.
Efficacy is specified in lumen [lm] per watt [W-1] and is typically 15 lm/W for conventional light bulbs, increasing to 30 lm/W for halogen, while as high as 150 lm/W for an LED. This high efficiency, combined with extended longevity, explains why LED technology has high market attraction with excellent growth and application potential.
A low free-cyanide silver process, containing innovative brightener additives, enables the highest luminous reflectance and performance of the LED.
