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(nèi)外同類產(chǎn)品或同類技術的比較情況:

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(nèi)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(nèi),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(nèi)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.
