【摘要】:基于現(xiàn)有的LED植物光源在植物培育中光照不均勻的問題,對目前的植物工廠中使用較為廣泛的紅、藍LED陣列型光源進行優(yōu)化設計。通過對比四種不同的LED陣列排布方式,采用9點法進行PPFD值的測量和光譜的測量,進一步觀察平面上光量子通量密度的均勻性和光譜分布的均勻性,進而尋求效果較好的LED陣列排布方式。結果表明:紅藍LED芯片交差分布和陣列行列交錯分布的排列方式有利于提高光源陣列光譜的均一性。
[Abstract]:Based on the problem of uneven illumination of existing LED plant light sources in plant cultivation, the red and blue LED array light sources which are widely used in plant plants at present are optimized and designed. By comparing four different arrangement methods of LED arrays, the PPFD values and spectra were measured by 9-point method, and the uniformity of optical quantum flux density and spectral distribution on the plane was further observed. Then we seek a better arrangement of LED array. The results show that the intersecting distribution of red and blue LED chips and the interlacing distribution of array columns are beneficial to improve the uniformity of the spectrum of the light source array.
