An LED lamp tube with built-in cooling base

technical field

The utility model relates to the technical field of LED lighting, in particular to an LED lamp tube with a built-in heat dissipation base.

Background technique

LED light tubes are also commonly known as LED light tubes, LED fluorescent tubes, and LED fluorescent lamps, and their light sources use LEDs as illuminants. Traditional fluorescent tubes are also called fluorescent lamps. There is a filament at each end of the lamp. The tube is filled with a small amount of argon and thin mercury vapor. The inner wall of the tube is coated with fluorescent powder. The gas between the two filaments emits ultraviolet rays when conducting electricity. Make phosphors emit visible light. Due to the heavy metal pollutant "mercury", the scrapped fluorescent tubes pollute the environment very seriously. The LED lamp uses light-emitting diodes as the light source, which has higher luminous efficiency, more energy-saving, longer service life, and is more environmentally friendly. It has become the most ideal product to replace fluorescent lamps at the current stage.

LED lamps are the same as traditional fluorescent lamps in size and diameter. There are T5 lamps, T8 lamps and T10 lamps, and the lengths are 0.6m, 0.9m, 1.2m, 1.5m, 1.8m and 2.4m.

The installation of LED lamp tube is very simple. When installing, the original fluorescent lamp is removed and replaced with LED lamp tube, and the ballast and starter are removed, so that 220V AC mains power can be directly added to both ends of the LED lamp tube.

LED lamps save electricity by more than 70%, and their lifespan is more than 10 times that of ordinary lamps (theoretically, it can reach more than 50,000 hours). It is almost maintenance-free, and there is no need to frequently replace lamps, ballasts, and starters. For the problem, the cost saved in about half a year can be exchanged for the cost. The green and environment-friendly semiconductor electric light source has soft light and pure color, which is beneficial to people's vision protection and physical health.
