LED lamps have beautiful appearance, energy saving, environmental protection, safety, long life, high efficiency, no radiation, and resistance.

After the film is released, the heat is still concentrated inside the tube and is not released. When the working time of the LED lamp is long, the internal temperature of the lamp will rise to a higher level, so that the LED lamp works under high temperature condition, and the LED lamp may be damaged under bad conditions, so that the service life of the LED lamp tube is shortened. The defect is worth solving.
