LED light illuminate After Edison 1879 invents the carbon filament incandescent, lighting technology has entered a new era. Recalling to the history of the 20th century lighting, fluorescent lamps, mercury lamps, high / low LED bulb pressure sodium, metal halide lamps, compact fluorescent lamps, high-frequency and microwave electrode less fluorescent and other new sources emerge in endlessly. Incandescent are born with congenital defects, tungsten heating high power consumption, light bulbs is fragile and easy to make electric shock. While saving energy is more saving than incandescent fluorescent, but unfavorable to human vision, the mercury inside is harmful to humans and the environment. Really cause a qualitative change in lighting technology is LED light. Compared with traditional lighting technologies, the biggest difference of LED is the different structures and materials; it is a semiconductor that can convert electrical energy into visible light, upper and LED light lower layers with electrodes, the middle is conductive material, the illuminated material in the two electrodes mezzanine, the color of light is depending on the material properties vary. LED are all solid cold light source, smaller in size, lighter, with more robust construction, and low operating voltage, practical and long life. According to the usual definition of luminous efficiency, LED luminous efficiency is not high, but the LED spectrum almost all concentrated in the visible light spectrum, efficiency is up to 80% to 90%. The visible efficiency equivalent incandescent light efficiency is only 10% to 20%, monomer LED's power is generally 0.05 ~ 1W, to meet the different needs through the cluster approach. LED as a new green product, is an inevitable trend of future development, the 21st century will enter the new era of LED lighting represented.LED grow light save more for your garden lighting Plants grow lights are used to enhance the rapid and healthy grow of indoor plant species. The plant lights mimic natural sunlight; its wavelength is most suitable for plant growth. Because of the different types of plants require different lighting requirements, the most common fluorescent lamps are LED grow lights. myledgrowupanty 140930
