Comparison of LED street lights and traditional street lights
Traditional street lights require a large power supply system. The difference between LED street lamp manufacturers and conventional street lamps is that the LED light source adopts low-voltage DC power supply, and is a high-efficiency white light synthesized by GaN-based power blue LED and yellow. It has high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and display. Unique advantages such as high color index can be widely used on roads. The outer cover can be made, the high temperature resistance can reach 135 degrees, and the low temperature resistance can reach -45 degrees. With the rapid growth of the national economy, the contradiction between my country's energy supply and demand has become increasingly prominent. There is a serious shortage of power supply, and energy conservation is an urgent problem to be solved. Therefore, the development of a new type of high-efficiency, energy-saving, long-life, high color rendering index, environmentally friendly LED street lamps is of great significance to the energy saving of urban lighting. Large power transformers are very expensive. The voltage of the traditional lamp will not fluctuate too much, otherwise it will seriously affect the life of the lamp. The LED street lamp uses Sunshine Shengyuan technology to drive the module and does not require a large transformer. When the voltage fluctuates, the brightness of the LED street lamp remains unchanged. T220C350W12S12 can drive 12WLEDs. When the voltage changes from 180V to 260V, the entire driver can achieve constant current drive. Ensure the brightness of high-power LED street lights. In addition, in abnormal situations, the driver has many protection functions and the reliability of the entire power grid.
Energy saving comparison between LED street lamps and traditional street lamps
Let's calculate the cost of electricity consumption for one year with three sections of road and two light sources. The calculation method is to turn on the lights for 10 hours a day, and calculate the electricity per kilowatt hour at 1 yuan. The annual power consumption of traditional street lamps on 3 kilometers of highway is 184,325 kilowatt-hours, which is 184,325 yuan. The total annual electricity consumption of LED street lights is 36,865 kWh, 36,865 yuan, 5 km traditional street lights 30 3863 kWh, 30 3863 yuan, 60 773 kWh, 10 km traditional street lights 60,773 kWh. The total electricity consumption is 607,725 kWh, 607,725 yuan, and the LED street lamp is 121,545 kWh, 121545 yuan.
