Technology has been advancing over time, and after enduring the long years of torches, candles, and kerosene lamps, humanity has finally developed to this day, creatively entering the era of using electricity as the lighting source. According to the principle of luminescence, it has gone through three stages of development: incandescent lamps, fluorescent lamps (including electronic energy-saving lamps), and semiconductor lamps (LED). The environment of human life has undergone significant changes over time and human factors, so we have begun to consider the concept of green and low-carbon living.
LED can become a new darling in the extreme energy shortage of the 21st century, and due to its many advantages, it will definitely surpass the era of incandescent and fluorescent lamps and lead the wave of the third lighting revolution.

LED is driven by DC, and under the same lighting effect, its power consumption is only 1/9 of that of incandescent lamps and 1/5 of that of fluorescent lamps. LED is a cold light source that generates almost no heat during use, thus saving a lot of electricity.
LED is a cold light source for lighting, with low voltage and low current, and does not rely on heat to emit light. Its service life can reach 50000 to 100000 hours. For outdoor high-power lighting street lights, one-time investment costs such as cables and poles can be greatly reduced in the early stage.

Usually, second-generation lighting fixtures that use the principle of high-voltage (vacuum) gas discharge are filled with toxic substances such as mercury, and the replaced waste also causes secondary environmental issues. Neon lights filled with inert gas are very fragile and often have short arms and legs, bringing another type of light pollution to urban landscapes. LED, on the other hand, emits solid light, is small in size, pollution-free, and recyclable. There is no ultraviolet or infrared light in the spectrum, no radiation, no heat. It does not contain any toxic or harmful substances that may harm health or damage the environment. It is truly 'green lighting'.
The concept of "green lighting" was proposed by foreign countries in the late 1980s. The implementation of "green lighting" in China was carried out in 1996. The important step is to promote efficient and energy-saving lighting products, save lighting electricity, and reduce environmental and light pollution.
LED has been widely used for lighting in public places such as stations, docks, airports, shopping malls, hospitals, hotels, securities markets, as well as for landscape art lighting in squares, gardens, and streets. According to reports, Beijing's "Water Cube" has set the world's largest precedent for LED landscape lighting.
