7 facts about LED’s that you may not know
Did you know that the LED with a visible-spectrum was invented in 1962 by Nick Holonyak, Jr. He worked with GE at that time. Since then, LED’s have not looked back and have seen steady rise in technical improvement and usage across the commercial as well as the domestic market spectrum. LED costs have also reduced drastically making them the ideal lighting solution for almost all needs.
- An LED (abbr. for Light Emitting Diode, is a kind of lighting technology that uses semiconductors in order to convert electricity into light. LED’s have been in use for a very long time, mostly on PCB and smaller applications. Technology has certainly evolved and today, an LED bulb is quite efficient and can work at about 20% of the power consumed by an incandescent bulb. This translates to 80% energy savings, which is substantial.
- LEDs are green and eco-friendly and are mercury-free thus making them ideal to reduce carbon footprints. LEDs are also more efficient that CFLs that are currently the growing trend.
- LED bulbs, manufactured with a qualitative process can run for over 25,000 hours compared to a traditional incandescent bulb that has an average life of 1000 hours. A good quality LED bulb, if run 24 X 7 can last for over 3 years.
- LED bulbs have varied uses, beginning from Vehicle brakes, vehicle day time lighting, brake lights, displays, televisions and many other applications. LEDs have unique characteristics like smaller footprint, low breakage, focussing capability, ease of maintenance and handling and many other factors.
- The secret to energy saving using an LED bulb is that it produces very low amount of heat compared to incandescent bulbs which use 90% of the energy consumed to produce and dissipate.
LED replacement lighting grew by over 22% between 2011 and 2012 and the cost fell by about 40% in the same period. According to market estimates, 75% of world lighting needs will be addressed by LED lighting.
Keeping these facts and figures in mind, we should look at changing to LED lighting as quickly as possible, either by replacing the existing traditional lighting systems or by replacing as and when necessary. You will not only save costs on your power bills, but also contribute to reduction of global warming, one by reducing consumption and second by opting for greener lighting systems.
