LED light source is a light source with light-emitting diode (LED) as a luminous body, which has five advantages: no mercury, energy saving, material saving, no electromagnetic interference to the environment, and no harmful rays. The LED light source is a low-voltage microelectronic product that uses electronic light field radiation to avoid the disadvantages of traditional light sources such as aging and burnout. At the same time, because of its small size, light weight, sturdiness and durability, it is not easy to break, and the actual service life is longer.
