Pristine white light creates an aura of peace and is therefore one of the most preferred source of lighting. Now taking advantage of the emerging Organic Light Emitting Diode or OLED technology you can enjoy a warm white light that helps in huge savings in your electricity bill besides being environment friendly.

 

It would be surprising to know that people spend more than $200 billions in energy bills every year and that the by products of light sources are the major contributors for the rising green house effect. With the introduction of white OLED all this is bound to change. White OLED brings with it amazing new features which are unavailable in the commonly used fluorescent lamps and incandescent bulbs.  Not only does this organic light sources brings a drastic reduction in the energy consumption, there is also a big reduction in the amount of heat that is produced by using conventional light sources thereby promoting the concept of green light. Also the absence of any hazardous substance like mercury that is used in regular CFL will also add to the popularity of the white OLED.

 

A bright white OLED has been effectively designed by scientist by making certain modifications in the original organic polymer layer present in OLED. White OLED has been achieved by mixing a little greenish-white emitting host Bis-zinc with a pinch of an orange-red fluorescent dye known as tetraphenylnaphthacene. The unadulterated white light emission is attained by passing a voltage of 20 Volts to this organic layer. This white OLED lighting is considered both safe and soothing for the eye of human beings.

 

Universal display company  had launched in the market a white OLED light panel with the energy efficiency of 102 lumen per watt which is way higher than the energy efficiency offered by incandescent bulbs( 15lm/watt) and fluorescent lamps (60-90 lm/watt). With growing energy crisis this tremendous breakthrough will surely benefit the people globally.

 

White OLED scores above their counterparts because they are exceptional diffuse emitters and with new techniques employed in their mass production, it is soon going to be extremely cost effective. Moreover, white OLEDs don’t disperse heat and are literally the “coolest” light sources around.

 

So bid adieu to hefty electricity bills and promote green earth initiative by buying white OLED light sources
