Led Lighting Energy Saving Technologies
Because of advantages of energy-saving, environmental protection, LED has become a major trend in the light industry. As the technologies and product attributes used in LED are very different from the traditional lamps, so the current safety standards and norms in general lighting is obviously not applicable for LED lights. To assist the industry to address this problem, this issue will explain the LED lighting technology and the scope of possible applications.
The LED lighting refers to lighting products using LED (Light-emitting Diode) technology as the main light source. LED is a solid-state semiconductor components, its use the forward current circulate to PN junction of the semiconductor, and then the isolated negatively charged electrons combine with the positively charged holes, the photon emission when two kinds of electric carrier combined with each other. Different types of LED can emit the different wavelengths of light from the infrared to the blue, and the purple to the ultraviolet. In recent years, a new development is to paint fluorescent powder on the blue LED, finally achieve the white light LED. The operation usually requires LED driver or power supply, the main function of drive or power supply is to converted the AC to DC, and at the same time to achieve the voltage and current consistent with LED to drive the matching components.
LED lamps with small bulb size, light weight, and packed by epoxy resin, can affordable high intensity mechanical shock and vibration, not easy to break, and with long brightness decay cycle, its lifespan up to 50,000-100,000 hours, far exceeding the traditional incandescent light (1,000 hours) and fluorescent tubes (10,000 hours). Since lifespan up to 5 to 10 years, so LED lamps not only can reduce the cost of replacement lamps significantly, but also because of the feature that can be driven by extremely small currents, when in the same illumination effects, the power consumption is only half of the fluorescent light.
But because a part of the LED technologies are still inadequate, there are shortcomings when used LED lights initially, including poor light quality (color performance, consistency, color temperature), problem of heat dissipation, and the high price, among which the heat dissipation problem will accelerate brightness decay and reduce the lifetime of circuit components. As the manufacturing technologies were developed sharply in the past decade, the above-mentioned shortcomings were also improved. Besides the light efficiency of cold wihite LED has reached 100 Lm / W in 2008, the light efficiency of warm white LED is expected to increase from 70 Lm / W to 100 Lm / W in 2010. Compared to current general light source: incandescent light bulbs about 15 Lm / W, fluorescent lamp about 45 ~ 60 Lm / W, HID light about 120 ~ 150 Lm / W, LED luminous efficiency have significant advantage; following is a comparison for LED lamps and other common lights:
white LED: Less heat, wide operating environment, small size, Anti-vibration, focus beam.
fluorescent lamp: Energy-saving, but fragile and contain pollution waste such as mercury issues.
Incandescent bulb: Low efficiency, high consumption, short lifespan, fragile
