How to improve LED technology?
LED manufacturers are claiming lamp lives in the order of 50,000 to 100,000 hours. However, the technology is developing so quickly that it is impossible for a manufacturer to test a lamp for this long before it is obsolete. A new testing standard now means lumen depreciation can be estimated to 36,000 hours.
As more manufacturers test to this standard, buyers will have greater certainty about the longer-term performance of their investment.Our experience in testing LEDs over the last two years has shown a great improvement in LED efficacy over that time” says Rowse. “At current rates of improvement, it is reasonable to assume that an efficacy of 150 lumen per watt will be achieved before 2015, and that lamps will then be commonly available with an overall efficacy of at least 120 lumens per watt. This would mean that an 18 or 20 watt LED could be confidently used to substitute a 36 watt fluorescent with no loss of light output.”
While waiting for LED technology to improve, building owners and managers should explore other options to reduce their fluorescent lighting energy use that have a fast payback and will provide both financial and environmental savings.With imminent legislative changes concerning the use of traditional power hungry bulbs, LED light will be the light source of the future. LED light is an innovative, environmental-friendly and economical light source for both domestic and industrial environment.
LED light is energy saving light source which is made up of multiple LEDs installed in the case. Not only it is energy saving, it is also environment friendly. As the entire structure of LED lighting does not contain any harmful chemical substance, therefore no special preparation is required during disposal. It is also UV-ray free.Energy-saving: The brightness for 12W led tube light approximately equals to that for 40W fluorescent tube light, it can save 70% to 80% Energy.
Environment-friendly: Traditional fluorescent tube light contains a large amount of mercury steam and once the tube is broken, the mercury will volatilize and cause pollution. LED tube lights on the other hand do not contain any mercury or lead. This together with the fact that the LED tubes can be recycled and used again greatly contributes to environment protection. This makes LED tube light the Green Lighting for the 21st Century.
