LED lighting and energy-saving lamps confrontation
as the incandescent light bulb out time gradually approaching, LED lighting and energy-saving lamps confrontation is more intense. In the two exchanges in the field of lighting, who can produce? So we are here to compare the characteristics of two kinds of lighting.
who more energy efficient?
CFL (compact fluorescent lamp in the same light output under the premise of use up 1/5 to 1/4 of ordinary incandescent lamp of electricity, which can save a lot of lighting electric energy and cost, so usually is also known as energy-saving lamps. Energy-saving lamps promotion strategy in China has a long history, from 2008 in the first fiscal subsidies and efficient lighting products launched more than 60 million energy-saving lamps, so far, the lamps and lanterns of energy-saving lamps in overall market share has reached 55%, at the same time, our country has become a major exporter of energy-saving lamps, domestic production of energy-saving lamps, 70% exported to overseas markets each year.
the LED is a solid-state semiconductor devices, it can be directly put DianZhuan into light, need only a third of its predecessor incandescent lamp energy consumption, and can achieve the same lights, also can make use of smart sensors and microcontrollers, a sharp rise in the equipment maintenance efficiency and reduce management costs, really bring extra energy saving effect and economic benefits.
whose service life is longer?
in accordance with the relevant national energy-saving lamps quality standard, a high quality energy-saving lamp light life should reach an average of 6000 hours. And some of the brands are more strict on light life, such as their current research and development of new types of spiral energy-saving lamps, light life can reach 10000 hours ( About a year or so) And, in use after 10000 hours, light intensity fell by 30%.
the service life of the theory of normal manufacturer of production of LED lights for about 80000 hours (commonly About 9 years) , data show that the high quality LED after 50000 hours of continue to operate, also can maintain more than 60% of the initial light levels. Also often have the manufacturer said the LED life of up to 100000 hours, in fact, this is just in the laboratory under the condition of constant temperature, constant humidity, constant current half-life ( Light attenuation in half the time) And not all LED life is very long, more not may not be damaged. The LED products should pass MOCVO ( Metal organic chemical vapor deposition process) Growth of epitaxial wafer, and then after thinning, segmentation, solid crystal, wire, packaging long roast, testing, testing and a series of technological process, every process to determine the length of service life of the LED. More importantly, the life of the drive power and reduce the heat generated by the LED chip is currently the important factors that affect the service life of the LED lighting.
who more environmentally friendly?
energy-saving lamps one of the most popular is the pollution to the environment. Because of working principle, energy-saving lamp tube of mercury inevitably become a pollution source. 1 only about 5 mg of mercury content of ordinary energy-saving lamps, only with a round bead pen, but after seep into the underground might produce 1800 tons of contaminated water. Due to the low boiling point of mercury, room temperature can evaporate, abandoned after energy-saving lamp tube broken, instantaneous can make around one hundred times on the chroma of mercury in air. And once in the body's levels of mercury can damage a person's central nervous system, the human body a suction 25 micrograms of mercury vapor can be lethal. In the aspect of CFL recycling and disposal in our country at present is still blank, a lot of broken energy-saving lamps as living garbage landfills or exposed to the air, serious damage to the environment.
is based on this, in order to highlight the difference between LED lighting and energy-saving lamps, the current more LED manufacturers began to stress & other; Green lighting & throughout; The concept of. LED lighting is a solid-state encapsulation, belongs to the cold light source, no mercury and other harmful substances, from the point of view of mercury pollution, its more advantages. But now scientists have for the LED light biological safety problem more and more attention, on January 9, 2011, the European Union has already begun to enforce EN 62471:2008 standards, required test LED lamp wavelength at 200 nm to 3000 nm range of optical radiation hazards, including radiation intensity and radiation intensity, and the damage to skin, eye, retina may make a rating.
although LED lighting on the various data beyond the CFL comprehensive energy-saving lamps, but at this stage in the early stage of the production process maturity, investment, lighting effect, and the price is still far superior to LED lighting, from domestic and international market demand and the requirement of energy conservation and emissions reduction, energy-saving lamps is still in the near future to replace incandescent and halogen lamps lighting products such as high energy consumption of the best choice. And from the perspective of long-term development, the advantages of LED lighting speak for themselves, to achieve more in the future lighting market achievement, the key lies in the foundation technology, fundamentally solve the LED lighting in the current problems encountered in the application of, for the people really show & other; Green & throughout; , high efficiency, energy saving, economy, practical product image.
