LED street lights have three advantages
The light emitted by the well-designed LED street lamp is clear, controllable and beautiful. The optical elements designed in the LED luminaire ensure that the light reaches where it belongs, which means less light is wasted.
Second, the maintenance cost and energy consumption of LED lamps are lower. Since most road lights are owned and operated by utility companies, the use of LEDs can reduce energy consumption by about 40%. At the same time, the more important saving is maintenance. Because the lumen output of high-pressure sodium lamps will decrease, high-pressure sodium lamps must be replaced at least every five years. The material and labor for a single bulb replacement may cost 80 to 200 US dollars. Since the life of LED lamps is three to four times longer than HID, the cost savings of a single maintenance will be very large.
Third, decorative LED street lighting is growing. With the improvement of technology and the reduction of manufacturing costs, lighting manufacturers can provide a wider range of decorative lighting options, which can imitate the lighting design of old-fashioned gas lamps, etc., which has very aesthetic advantages.
