Description

一种具有散热功能的LED灯管 A kind of LED lamp tube with cooling function

技术领域technical field

本实用新型属于LED灯领域,特别是涉及一种具有散热功能的LED节能灯管。The utility model belongs to the field of LED lamps, in particular to an LED energy-saving lamp tube with heat dissipation function.

背景技术Background technique

LED是英文light emitting diode(发光二极管)的缩写,它的基本结构是一块电致发光的半导体材料,置于一个有引线的架子上,然后四周用环氧树脂密封,起到保护内部芯线的作用。发光二极管的核心部分是由p型半导体和n型半导体组成的晶片,在p型半导体和n型半导体之间有一个过渡层,称为p-n结。在某些半导体材料的PN结中,注入的少数载流子与多数载流子复合时会把多余的能量以光的形式释放出来,从而把电能直接转换为光能。在能量转换的过程中其电路板及电源等难免会散发出一定的热量。而且LED灯处于完全封闭的环境,热量散发不出来。目前,LED灯支架很多双面板、多层板密度高、功率大,热量散发难。常规的印制板基材如FR4、CEM3都是热的不良导体,层间绝缘,热量散发不出去。这样就会导致电子元器件高温失效。LED is the abbreviation of English light emitting diode (light emitting diode). Its basic structure is a piece of electroluminescent semiconductor material, placed on a shelf with leads, and then sealed with epoxy resin around it to protect the inner core wire. effect. The core part of a light-emitting diode is a wafer composed of a p-type semiconductor and an n-type semiconductor, and there is a transition layer between the p-type semiconductor and the n-type semiconductor, which is called a p-n junction. In the PN junction of some semiconductor materials, when the injected minority carriers recombine with the majority carriers, the excess energy will be released in the form of light, thereby directly converting electrical energy into light energy. In the process of energy conversion, its circuit board and power supply will inevitably emit a certain amount of heat. Moreover, the LED lamp is in a completely closed environment, and the heat cannot be emitted. At present, many LED light brackets have double-sided boards and multi-layer boards with high density and high power, and it is difficult to dissipate heat. Conventional printed board substrates such as FR4 and CEM3 are poor conductors of heat, and the interlayer insulation prevents heat from being dissipated. This will lead to high temperature failure of electronic components.
