The guidelines for Led Public lighting(CLASSICLEDLIGHT) design are based on the "led public lighting design specification standards and the LED lighting industry". This standard is formulated to ensure that urban road lighting can create a good viewing environment for vehicle drivers and pedestrians, and to achieve safe transportation, improve transportation efficiency, facilitate people's lives, prevent criminal activities and beautify the urban environment.
1. Lighting LEDs The main feature of public lighting is the ability to directionally emit light, since power LEDs are almost always equipped with reflectors, and the efficiency of such reflectors is significantly higher than the reflector efficiency of the lamps. In addition, the efficiency of the self-reflector has been included in the LED efficacy detection. Public lighting using LEDs should utilize the characteristics of directional emitted light of LEDs as much as possible, so that each LED in the public lighting fixture directly directs the light to each area of the illuminated road surface, and then uses the auxiliary light distribution of the luminaire reflector to A comprehensive light distribution that achieves very reasonable public lighting.
2. The LED public lighting power system is also different from the traditional light source. The constant current driving power supply required by the LED is a cornerstone to ensure its normal operation. The simple switching power supply scheme often brings damage to the LED device. How to make a group of LEDs tightly compressed together is also an indicator of LED public lighting. The requirement of the LED for the driving circuit is to ensure the characteristics of the constant current output. Because the relative change region of the junction voltage is small when the LED is working in the forward direction, the constant driving current of the LED ensures that the output power of the LED is constant.
