What is the main difference between LED street lights and solar street lights
Solar street lights refer to lamps that use sunlight to generate electricity instead of alternating current.
The principle is: the sun shines on the solar panel, which usually converts the light into electricity, and then provides the main current for the lamp. At present, due to the low conversion rate, the general solar lamp can be lighted for a short time, usually using a smaller power LED light source As a light bulb (a few watts, more than ten watts, to more than 50 watts, basically seldom can light up for a long time). The advantage is that it uses solar energy, saves electricity, and is environmentally friendly.
The LED street lamp refers to the street lamp that uses LED as the light source. At present, the most professional one in China is Kingsun Optoelectronics. It has been used on the Guangzhou-Shenzhen Expressway. However, street lamps have strict requirements for fog permeability and long life. Although the LED light source is claimed to have a life span of 100,000 hours, its drive is usually useless in one or two years. In fact, the overall life of the LED light source can be more than one year or two years. The so-called LED energy saving is not an ideal data obtained under experimental conditions. The premise of the life span of 100,000 hours is that the LED power supply and driver have been in normal use. And no matter which brand of LED, the luminous decay is unavoidable, and it is not bad if it can maintain the original brightness of 80% after two years.
The advantage is the small size, which provides more light source options for lamp manufacturers, and the color of the light is more diversified. After solving the current and driving and price problems in the future, it is expected to become popular. It is an effective light source for energy saving.
