LED street lamp used in street lamps and lanterns have what advantage

Specially light shape design of the application on the lamps and lanterns of street lamp, led wall lamp manufacturer can offset in the luminous point of the lamps and lanterns, improves the utilization rate of road next to the lighting; According to the aspect ratio of rectangle can occur the aspect ratio of 2:1 flare, so between adjacent flare

 specially light shape design application on the lamps and lanterns of street lamp, led wall lamp manufacturer can offset in the luminous point of the lamps and lanterns, raised the road next to the lighting efficiency; Based on rectangular aspect ratio can occur the aspect ratio of 2:1 flare, so will not appear between adjacent light shadow, can constitute a bright light on the road the uniform light, and thus more in line with the current traffic road lighting design, not demand progress in the shine of the light pole height can meet meet wide scale, and it also advances the efficiency of the lighting of lamps and lanterns, fell on the way of lighting power density ( Lighting power density ( LPD) Definition: building a room or place, lighting installation power per unit area ( Including ballast, transformer power consumption) , the unit is: watts per square metre. 】 , then the real to energy saving and environmental protection with high power LED street light [ LED street lamp is made of street lamp, LED lamps and lanterns with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, the city lighting energy saving is of great significance. 】 Lamp used for road lighting, compared with traditional high pressure sodium lamp has incomparable advantages: 1. Light-emitting mechanism is different, because the LED street lamp is a kind of semiconductor devices, the useful life of up to 50000 hours ( Namely after 50000 hours, light failure is less than 30%) , far higher than that of sodium lamp and metal halide lamp ( Metal halide lamp ( Metal Halide Lamp） Is ac power, working in mercury and rare metal halide mixture vapor arc discharge in glowing discharge lamp, metal halide lamp is on the basis of high pressure mercury lamp add various metal halide made of the third generation light source. 】 （ Their life spans about - in 12000 15000 hours) 。 2. Because the LED street lamp is a semiconductor material, no filament and other additional information, so it's good vibration resistance. 3. LED street lamp light source lighting color rendering index [ Light source for color is called color rendering of the object, is by reference or reference light source with same color temperature ( Incandescent lamp or light) The comparison of the object color appearance. 】 Can be reached more than 80, more close to natural light, the eye in this case are more likely to distinguish between things, is conducive to safety; And color rendering index as long as 20 - high pressure sodium lamp 30. 4. The traditional gas discharge lamp ( Gas discharge lamp is composed of gas, steam or several metal and glowing gas and the mixture of metal vapor discharge lamp. 】 If you have a high pressure sodium lamp in a preheating process, which wastes energy and is not conducive to intelligent control; LED street lamp lights for the light source has essentially difference, does not exist the problem of 'start time', and electricity can be immediately to normal operation, can complete intelligent energy-saving control is very convenient. 5. Because traditional street lamps light source are chosen to light the mechanism of mercury vapor, therefore, the processing of waste light source is now all international problems to be solved, and the luminescence mechanism of traditional light source resolution announced it will be harmful to human body of ultraviolet ray. LED street lamp light source is solid state lighting' Solid state lighting ( Solid— StateLighting, SSL) Is a new kind of lighting technology, the use of semiconductor chip as a luminescent material, converts electrical energy into light energy directly, it with incandescent tungsten light and energy-saving light glow sanki toner, semiconductor light-emitting diode ( 领导) The electroluminescence, photoelectric conversion efficiency is higher. 】
