項目名稱：  LED燈管制造工藝中的石墨烯導熱膜技術

Graphene Thermal Conductive Film Technology in LED tube Manufacturing Process

申報單位：  浙江金陵光源電器有限公司

綜合介紹或申報理由：

該技術將3－9個分子層厚度的石墨烯涂到燈管的內壁，形成幾乎全透明的散熱膜，使得LED芯片的散熱面積由線狀變?yōu)槊鏍?，更好地解決LED燈管的散熱問題。本項目的研發(fā)將徹底解決LED直管燈不能以相同的光通量替代三基色熒光燈的重要技術難題，對于項目而言，可使用本項目的22W燈管以相同的光通量取代36W三基色熒光燈的水平，開創(chuàng)了LED燈管用于替代傳統(tǒng)熒光燈的新領域。

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.

主要技術參數(shù)：

（1）光效(luminous efficiency)≥135 lm/W

（2）顯色指數(shù)(color rendering index)Ra≥80

與國內外同類產(chǎn)品或同類技術的比較情況：

目前，除公司之外，采用石墨烯作為散熱涂層的LED燈管在國內外尚未發(fā)現(xiàn)。

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.

經(jīng)濟評價分析：

本項目為LED燈管在室內照明領域完全徹底地取代傳統(tǒng)照明光源鋪平了道路。如果要用本項目22W燈管替代36W三基色熒光燈，在近10年內，每年全球的需求量為2000——5000萬支，銷售額為4000萬元到1億元。

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.

技術及工藝創(chuàng)新要點：

本技術先將單層石墨烯分散于二苯胺磺酸鈉等溶劑中制成膠體，涂覆于玻璃燈管內壁，制成導熱膜。在導熱膜的上再涂上一層由二氧化硅層、硅酸鉀和氟化鎂等組成的減反射膜，而后在這層減反射膜上再涂上一層漫反射涂層。 漫反射膜可以將LED芯片上發(fā)出來的熱量快速傳導到玻璃管上表面，讓燈珠始終處于最佳的工作狀態(tài)，從而大大提高了光效。

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.

實際運用案例和用戶評價意見：

采用本技術的燈管于2019年開始進入市場之后，用戶反映良好。公司已經(jīng)開始接受大批量的訂單。

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.
