LED uses semiconductor light-emitting diodes.
LED street lights use high-brightness white light-emitting diodes as the light source, which have high light efficiency, long lifespan, easy control, safety, and environmental friendliness. They are energy-efficient street light products that save more electricity than ordinary energy-saving lamps. They provide high brightness, long-range illumination, and operate within a wide voltage range. The light source can achieve seven colors through a built-in microcomputer controller, and the light is soft, vibrant, low energy consumption, and environmentally friendly, suitable for long-term lighting in homes, shopping malls, hotels, restaurants, and various public places.
Compared with incandescent tubes or low-pressure fluorescent tubes, the stability and longevity of LED lights are significant advantages. Incandescent bulbs rarely last more than 1,000 hours, and fluorescent tubes with electronic drivers can last over 8,000 hours, but LEDs can work without failure for more than 50,000 hours.
Due to the advantages of energy efficiency, environmental protection, long lifespan, and compact size, experts regard LED lighting as a significant advancement in the history of human lighting, following incandescent and fluorescent lamps. High-power LED street lights can be directly connected to 100-240V AC power sources and are considered environmentally friendly. The spectrum generated by LED street lights contains no ultraviolet or infrared light, no heat or radiation, making it a green light source. Each LED lamp saves approximately 503.7 kWh of electrical energy annually compared to a typical 150W energy-saving lamp. The lamp head is made of die-cast aluminum alloy, and the lampshade uses high-quality tempered glass, providing excellent light transmittance and dust and waterproof properties. The complete set of fasteners is made of stainless steel, and the product surface has environmentally friendly fluorocarbon powder electrostatic spraying, ensuring good self-cleaning properties.
Lighting costs involve not only the initial cost of fixtures but also the energy costs consumed by the fixtures and the labor costs of replacing fixtures when they fail to operate. The price of LED light sources is about 50 times that of incandescent light sources. Currently, semiconductor lighting mainly focuses on color lighting and special lighting, with plans to expand into general lighting in the future, covering areas such as beautification of squares and streets, decorative lighting for homes, and enhancement of public entertainment venues.
