(1) Energy conservation has the characteristics of low voltage, low current, and high brightness. The LED light used as Led Public lighting must have the characteristics of low voltage, low current and high brightness to ensure the normal use and high efficiency and energy saving during installation.(2) A new type of green and environment-friendly light source. LED uses a cold light source with small glare and no radiation and does not emit harmful substances in use. LED has better environmental protection benefits, no ultraviolet and infrared rays in the spectrum, recyclable waste, no pollution of mercury-free elements and safe touch, and belongs to a typical green lighting source.(3) Long service life. Since LED public lighting needs to be used continuously, it is also troublesome to replace it in batches when replacing it, so long service life is also an important factor when selecting it.(4) The light structure is reasonable. The LED light will completely change the structure of the light. According to different use requirements, the structure of the LED light will increase brightness again through rare earth under the condition of improving initial brightness, and its luminous brightness will be further improved through the improvement of optical lenses. LED is a solid-state light source encapsulated with epoxy resin, and its structure is an all-solid structure without easily damaged components such as glass bulb filament, so it can withstand shock impact without being damaged.(5) simple light color, light color. As a street light, LED public lighting must have a simple light color and need not too much noise. It is necessary to ensure road safety while ensuring lighting brightness.(6) High safety. The LED light source is driven by low voltage, stable in light emission, pollution-free, free from stroboscopic phenomenon when 50Hz AC power supply is adopted, free from ultraviolet B band, color rendering index Ra bit close to 100, color temperature 5000K, and the color temperature 5500K closest to the sun. It is a cold light source with low calorific value and no thermal radiation, and can accurately control the light type and luminous angle, with soft light color and no glare. And does not contain mercury, sodium and other substances that may harm LED public lighting.
