随着社会科技的发展,作为相对环保能源,在人们的日常生活中LED灯的应用也越来越广泛,LED灯由于具有美观、节能、环保、安全、寿命长、效率高、无辐射、抗冲击等优点,已经得到越来越广泛的使用,但由于灯管两端装上连接端子后,使LED灯板处于灯管及其两端的端子组成的封闭空间,即使LED灯产生的热量经过散热片散发后,热量仍集中于灯管内部得不到释放。当LED灯工作时间较长后,灯管内部温度会上升到一个较高的水平,使LED灯处于高温状态下工作,恶劣情况下可能造成LED灯损坏,使LED灯管的使用寿命缩短,所述缺陷值得解决。With the development of social science and technology, as a relatively environmentally friendly energy source, LED lamps are used more and more widely in people's daily life. 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.
