Low calorific value, no thermal radiation, cold light source, safe touch: precise control of light type and light emitting angle, soft light color, no glare; Does not contain mercury, sodium and other substances that may be harmful to health. Built-in microprocessor system can control the luminous intensity, adjust the luminous mode, and realize the combination of light and art. LED is an all-solid-state luminous body, which is earthquake-resistant and impact-resistant, not easy to break, and the waste can be recycled without pollution. The light source is small in size, can be combined at will, and is easy to develop into a light, thin, short and small lighting product, and is also convenient for installation and maintenance. Of course, energy saving is the main reason why we consider using LED light sources. Perhaps the LED light source is more expensive than the traditional light source, but it will take one year to recover the investment of the light source, and it will take several times a year to get the net benefit period of energy saving in 4 ~ 9 years.
