How is LED Street Light different from traditional street lights?

Light source type:
LED Street Light uses LED (Light Emitting Diode) as the light source, which is a solid-state light source made of semiconductor materials. The light-emitting principle of LED is that when current passes through a semiconductor material, it stimulates electron transition to generate photons, so LED has high photoelectric conversion efficiency. In contrast, traditional street lights usually use traditional light sources such as high-pressure sodium lamps (HPS), fluorescent lamps or metal halide lamps. Their light-emitting principle is to emit light through gas discharge or electron excitation of fluorescent substances. LED light sources are more stable, durable, and energy-saving than traditional light sources, and have broader application prospects.

2. Energy efficiency ratio:
LED Street Light has a higher energy efficiency ratio, mainly because the LED light source has high energy conversion efficiency. The photoelectric conversion efficiency of LED is usually above 80%, while the energy efficiency of traditional street lights is relatively low, generally around 30% to 50%. This means that LED Street Light can consume less energy at the same brightness, thereby achieving the purpose of energy saving and emission reduction.

3. Energy saving performance:
LED Street Light has better energy-saving performance. This is because the energy utilization rate of LED light source is high and it can convert more electrical energy into light energy. In contrast, traditional street lights have high energy consumption and waste a lot of electrical energy. . According to statistics, the energy consumption of LED Street Light is usually more than 50% energy-saving than traditional street lights, which is of great significance for urban energy conservation and emission reduction, and reducing energy consumption.

4. Light quality characteristics:
LED Street Light has better light color adjustability. LED light sources can achieve different color temperatures and color performances, which can better meet the lighting needs of different occasions. The light color temperature of LED Street Light is usually adjustable between 3000K and 6500K. The appropriate light color can be selected according to specific application scenarios. For example, 3000K warm white light is suitable for residential areas, parks and other places, while 6500K cold white light is suitable for roads. , highways and other places that require high brightness.

5. Lifespan and maintenance:
LED Street Light has a long life, usually reaching tens of thousands of hours, and has less light decay problems, reducing the frequency of maintenance and replacement of lamps. The life of LED is mainly affected by factors such as LED chip, heat dissipation structure and driving power supply. Reasonable design and selection of materials can improve the life of LED Street Light. In contrast, traditional street lights have a short lifespan and require frequent replacement of bulbs and maintenance of lamps, which increases the cost and workload of urban lighting management.

S4 Low Harmonic Street Light
Low Harmonic Street Light typically refers to a type of street light designed to have a reduced impact on the harmonic distortion of the electrical power system. Harmonic distortion occurs when the normal sinusoidal waveform of the electrical voltage or current gets distorted due to the presence of non-linear loads, such as electronic devices and lighting systems.
