Humans have been using incandescent light bulbs for over 130 years. Long before Edison, British electrical engineer j. Swan began research on electric lights from the late 1840s. After nearly 30 years of hard work, Swan finally found a carbon filament suitable for filament.
After more than one hundred years of development, the constant innovation of science and technology has also led to the "elimination" of some old products. So what's the difference between LED street lights and ordinary street lights? Compared with ordinary street lights, what are the advantages of LED street lights?
What are the advantages of LED lights?
1. High efficiency and energy saving: only a few kilowatt hours of electricity for one thousand hours! (Ordinary 60W incandescent lamp consumes 1 degree of electricity in 17 hours, and ordinary 10W energy-saving lamp consumes 1 degree of electricity in 100 hours.) 2. Super long life: semiconductor chip emits light, no filament, no glass bulb, not afraid of vibration, not easy to break, service life Up to 50,000 hours (the life of ordinary incandescent lamps is only 1,000 hours, and the life of ordinary energy-saving lamps is only 8,000 hours) 3. Healthy light: The light does not contain ultraviolet and infrared rays, and does not generate radiation! (Ultraviolet and infrared rays are included in ordinary light lines)
4. Green environmental protection does not contain harmful elements such as mercury and xenon, which is conducive to recycling and does not generate electromagnetic interference (elements such as mercury and lead are contained in ordinary lamps, and electronic ballasts in energy-saving lamps will generate electromagnetic interference) 5. Vision protection: LED energy-saving lamps are driven by DC, no flicker (common lamps are AC-driven, with flicker) 6. High light efficiency: LED energy-saving lamps generate less heat, and 90% of electricity is converted to visible light (80% of ordinary incandescent lamps) The electrical energy is converted into thermal energy, and only 20% of the electrical energy is converted into light energy.) 7. High safety factor: The required voltage and current are small, the heat is small, and there is no hidden safety hazard. It is used in dangerous places such as mines.
LED street light is a street light using semiconductor light emitting diodes as the light source. LED street lights are highly energy-efficient and ultra-low power consumption. The energy consumption of white LEDs is only 1/10 of that of incandescent lamps and 1/4 of energy-saving lamps. And the LED light source does not contain harmful metal mercury. The LED street light source has a small loss of luminous flux. Unlike traditional light sources, LED street lights are half-space light sources.
So what exactly is a traditional street lamp?
Traditional ordinary street lamps generally use high-pressure sodium lamps, which have a low overall luminous efficiency and 360 ° light emission, which not only causes a huge waste of energy, but also generates large amounts of heat and has a short life. A high-pressure sodium lamp is a light source that emits light in a full space. It is necessary to change the direction of the light emitted from one half of the space to the reflector in the other half of the space. At the same time, it is inevitable to absorb light and block the light source itself.
The use of LED lights as the light source does not cause losses in this respect, and the utilization ratio of light is higher than that of high-voltage nano-lights.
In fact, no matter in energy saving, use time, quality and later maintenance, the performance of LED street lights is better than traditional street lights, and the color light of LED street lights is brighter than traditional street lights. The color cast of traditional street lights is more serious. LED Street lights are much better.
