LED灯管制造工艺中的石墨烯导热膜技术——2020神灯奖申报技术

项目名称：  LED灯管制造工艺中的石墨烯导热膜技术

Graphene Thermal Conductive Film Technology in LED tube Manufacturing Process

申报单位：  浙江金陵光源电器有限公司

综合介绍或申报理由：

该技术将3－9个分子层厚度的石墨烯涂到灯管的内壁，形成几乎全透明的散热膜，使得LED芯片的散热面积由线状变为面状，更好地解决LED灯管的散热问题。本项目的研发将彻底解决LED直管灯不能以相同的光通量替代三基色荧光灯的重要技术难题，对于项目而言，可使用本项目的22W灯管以相同的光通量取代36W三基色荧光灯的水平，开创了LED灯管用于替代传统荧光灯的新领域。

The technique applied graphene with 3-9 molecular layer thickness to the inner wall of the lamp tube to form a nearly fully transparent heat dissipation film, which made the heat dissipation area of the LED chip change  linear to surface, which could better solve the heat dissipation problem of the LED lamp tube. The research and development of this project will completely solve the important technical problem that LED straight tube lamp can not replace three-color fluorescent lamp with the same luminous flux. For the project, the 22 W lamp tube of this project can be used to replace 36 W of three-color fluorescent lamp with the same luminous flux, which opens up a new field of LED lamp tube to replace traditional fluorescent lamp.

主要技术参数：

（1）光效(luminous efficiency)≥135 lm/W

（2）显色指数(color rendering index)Ra≥80

与国内外同类产品或同类技术的比较情况：

目前，除公司之外，采用石墨烯作为散热涂层的LED灯管在国内外尚未发现。

At present, in addition to the company, the LED lamp tube using graphene as heat dissipation coating has not been found at home and abroad.

经济评价分析：

本项目为LED灯管在室内照明领域完全彻底地取代传统照明光源铺平了道路。如果要用本项目22W灯管替代36W三基色荧光灯，在近10年内，每年全球的需求量为2000——5000万支，销售额为4000万元到1亿元。

This project paves the way for the LED lamp tube to completely replace the traditional lighting source in the field of indoor lighting. To replace 36 W tricolor fluorescent lamps with the 22 W lamp tube of this project, in the last 10 years, the annual global demand is 20～50 million, and the sales volume is 40 million Yuan RMB to 100 million Yuan RMB.

技术及工艺创新要点：

本技术先将单层石墨烯分散于二苯胺磺酸钠等溶剂中制成胶体，涂覆于玻璃灯管内壁，制成导热膜。在导热膜的上再涂上一层由二氧化硅层、硅酸钾和氟化镁等组成的减反射膜，而后在这层减反射膜上再涂上一层漫反射涂层。 漫反射膜可以将LED芯片上发出来的热量快速传导到玻璃管上表面，让灯珠始终处于最佳的工作状态，从而大大提高了光效。

In this technique, monolayer graphene was first dispersed in solvent such as sodium diphenylamine sulfonate to make colloid, coated on the inner wall of glass lamp tube, and made into thermal conductive film. A layer of antireflection film consisting of SiO2 , K2SiO3  and MgF2  is applied to the thermal conductive film, and then a diffuse reflection coating is applied to the film.diffuse reflection film can quickly transmit the heat emitted  the LED chip to the upper surface of the glass tube, so that the lamp beads are always in the best working state, thus greatly improving the luminous efficiency.

实际运用案例和用户评价意见：

采用本技术的灯管于2019年开始进入市场之后，用户反映良好。公司已经开始接受大批量的订单。

After the lamp tube with this technology began to enter the market in 2019, the user reflected well. our company has started to accept large orders.
