| Building lighting problems Modern office building energy saving of lighting requirements more and more high, not only required to provide comfortable, adequate lighting to meet the lighting business office staff health requirements, but also to meet the social requirements of green, energy saving. The office building is generally equipped with underground parking, public lighting using energy-saving lamps of traditional and high power light source, the annual electricity expenditure amount is not small, lighting electricity consumption accounted for about fifty percent, reduce lighting energy consumption has become a problem of office building; If the building of public lighting source part of the LED lamp model of green light source, in the premise of not changing the original circuit to replace the existing light source, to achieve energy saving forty percent than the traditional lighting; Energy saving retrofit scheme of building lighting Principle of traditional lighting: light emitting principle is not the same, the common incandescent lamp directly to electricity installed into light and heat energy, energy saving lamp is the electron in the potential under the function of the fluorescent powder to emit light to reach the purpose of lighting, The principle of LED lamp: is through the light-emitting diode to electric energy into light energy. The advantages of the contrast between lighting: 1, the traditional incandescent lamp: low cost, good color rendering, but life is short; 2: as the name suggests, LED energy-saving lamp energy saving, energy saving and emission reduction in response to the government call...... , more energy saving, no pollution (mercury) more environmental protection; the original design for the general lighting, energy-saving lamps, halogen tungsten lamp, high energy consumption, instead of white LED lighting, lighting energy consumption will decrease. On the LED with the traditional lighting brightness and energy efficiency comparison: 1W LED=3W CFL (=15W incandescent lamp energy saving lamp) 3W LED=8W CFL (=25W incandescent lamp energy saving lamp) 4W LED=11W CFL (=40W incandescent lamp energy saving lamp) 8W LED=15W CFL (=75W incandescent lamp energy saving lamp) 12W LED=20W CFL (=100W incandescent lamp energy saving lamp) Recommend the use of lamps and lanterns
