Advantages of energy-saving lamps and LED lights

　　Energy saving lamp is the official full name of rare earth trichromatic compact fluorescent , high luminous efficiency, energy-saving effect , long life , small size, ease of use . It works basically the same and fluorescent lamps . In addition to energy-saving lamps white ( cold ) outside , there is still blue ( warm light) . Generally under the same wattage , an energy-saving lamps than incandescent energy saving 80% , the average life expectancy eight times , only 20% of the thermal radiation . Under non- stringent conditions , a 5 -watt energy-saving lights shine can be seen as equal to 25 watt incandescent , 7 -watt energy-saving light shines equal to about 40 watts , 9 watts equal to about 60 watts . The 1970s was born in the Netherlands, Philips , refers to a combination of fluorescent lamps and ballasts or ballast lighting as a whole . Energy-saving lamps and incandescent similar size , with the incandescent lamp socket interface and also the same , so you can directly replace incandescent lamps . Currently 80% of the country 's energy-saving lamps from Guangdong production, of which 80 % energy saving lamps are manufactured in Zhongshan . This light is the same light output reached under the premise , just ordinary incandescent electricity consuming 1/5 to 1/ 4 , which can save a lot of energy and lighting costs , so called energy-saving lamps .

　　LED lights called light-emitting diode , which is a solid-state semiconductor devices, can be directly into electricity to light. LED 's heart is at one end of a semiconductor wafer , the wafer is attached to a frame, one end is the anode, and the other end connected to the positive power supply , so that the whole chip is epoxy encapsulated . Semiconductor wafer consists of three parts , one part is a P-type semiconductor , the hole in it dominates , the other side is N -type semiconductor, here is mainly electronic , in the middle is usually quantum wells 1-5 cycles. When the current through the wire on the chip , the electrons and holes will be pushed to the quantum well , electron hole recombination , and will be issued in the form of photon energy in the quantum well , which is the principle of LED light .

　　LED lamps have a small size, low power consumption, long life , non-toxic environmental protection and many other advantages , LED lighting from outdoor decoration , lighting projects , and gradually developed into household lighting .

　　Energy saving lamp incandescent energy conversion rate is relatively much higher , save energy , it can be said that reducing greenhouse gas emissions , long service life.

　　Energy-saving lamps disadvantages:

　　1 , Energy saving lamps slow start .

　　2, Energy-saving lamp is bright line spectrum , it is usually purplish light energy-saving lamps , energy-saving lamp to see things seriously discolored. Blue becomes purple, red and yellow will look more vivid. So the color of the workplace should not use energy-saving lamps.

　　3, After a long research scientist preliminary conclusion : energy saving lamp radiation may pose a risk to human health or even cause cancer.

　　LED lamp advantages:

　　High energy: saving energy is clean and is environmentally friendly. DC drive, ultra-low power electro-optical power conversion close to 100% , the same lighting effects than traditional energy sources more than 80%.

　　Long life : LED light source that some people call longevity , meaning light never goes out . Solid cold light source , epoxy resin, light body and no loose parts , there is no filament light easy to burn , heat deposition , the light fades and other shortcomings , the service life up to 60000-100000 hours , 10 times longer life than conventional light sources above .

　　Multi- changes: LED light source can make use of red, green and blue color theory , under the control of computer technology to make three kinds of colors with 256 gray scale , and any mix , you can generate 256 × 256 × 256 = 16777216 colors to form a different light combination of changing color to achieve a variety of dynamic effects and variety of images.

　　Lee Green : Environmental benefits of better, no ultraviolet and infrared spectra , neither heat nor radiation , glare small and recyclable waste, no pollution, no mercury elements, cold light source , safe touch , typical of the green lighting.

　　Tech tip : Compared with traditional light glow monotonous , LED lighting is low voltage microelectronic products , the successful integration of computer technology, network communication technology, image processing technology, embedded control technology, so it is also digital information products , is semiconductor optoelectronic devices " high point" technology, with online programming , unlimited scalability , flexible features .

　　LED lamp disadvantages:

　　1, LED lamps can not completely replace the incandescent lamps ; flux, luminous efficiency and color rendering can be , but is too expensive and not decreased in recent years . But you can replace incandescent lamps to reduce costs through improved product flux.

　　2, LED light source can not be simply use in common ; its use to drive power, with optical and thermal conductivity .

　　3, LED lights will also heat required cooling.

　　Overall, the odds ratio for its energy-saving lamps over incandescent lamps , LED lamps , but because it 's more environmentally friendly and energy-saving features and energy-saving lamps with fair competition . We have to believe that , in later life , the use of LED lights people will more and more.
