Incandescent lights in the 20th century, and led lamp illuminated street lamp light

As the latest generation of lighting source, LED lamp, Street light, solar street lamp, garden lamp, mining lamp, etc. ) With its high light efficiency, environmental protection, energy saving, long life unique advantages has been widely used, and will get faster development: a, led lamps and lanterns consumption

as a new generation of lighting source, led lamp, Street lamp, solar street lamp, garden lamp, mining lamps, etc. ) Because of its unique high photosynthetic efficiency, environmental protection, energy saving and long service life and the advantages of widely used, and will get faster development. First of all, the led lamps and lanterns with high power and high photosynthetic efficiency, very energy saving. General incandescent light efficiency between 11 to 17 lumens per watt, halogen tungsten lamp light efficiency between 14 to 26 lumens per watt, fluorescent light efficiency between 52 and 95 lumens per watt, the metal sodium lamp light efficiency of traffic signal lamp manufacturers in between 85 and 150 lumens/watt, and the light efficiency of light emitting diode has now reached 90 to 300 lumens per watt ( Lab has reached more than 400 lumens/watt) , and monochromatic light is good, can direct emission color visible light. Under the same lighting effect, power consumption is less than one over ten of incandescent bulbs. Second, the light emitting diode low working voltage ( Only 2 - DC 3. 6 v) And very low power consumption, especially suitable for ac power or cable laying no convenient area lighting. Led lights need only very weak electric current can normal light. A light emitting diode lamp of illumination is only 0. 6 watts, whereas a only 1 watt led lamp, especially suitable for solar street lamps. Third, led lights can be made into various shapes of dot, line, surface products, very convenient to control: by regulating current, free to adjust light intensity, using sequential control circuit, can realize the colorful light color changing effect. Green environmental protection, long service life. Led light source adopts the semiconductor light-emitting, belong to solid cold light source. It has small volume, light weight, not afraid of vibration. Its service life can reach 50000 - 100000 hours. No uv or infrared, the spectrum can waste recycling, no pollution to the environment. It is a kind of high quality green lighting light source, has been widely used in street light and solar street light. Incandescent lamp lit up in the 20th century, and led lamp will light up the 21st century.
