【摘要】：在可見光通信系統(tǒng)中,光源具有照明和通信的雙重作用,由于房間的大小以及室內(nèi)環(huán)境各不相同,難免會(huì)存在光照射不到或者光線比較微弱的地方,這些地方很有可能成為通信的盲區(qū),這將會(huì)大大影響通信的質(zhì)量,為了解決陰影效應(yīng),需合理對(duì)光源進(jìn)行布局設(shè)計(jì),以4 m×4 m×3 m房間為模型,采用四個(gè)LED列陣作為室內(nèi)光源,將單個(gè)的LED光源看做朗伯光源,服從朗伯輻射模型,通過公式計(jì)算結(jié)合軟件仿真分析對(duì)比得出了采用9×9大小的LED列陣,列陣距離屋頂邊緣0.4 m,LED光源間的間距為0.03 m時(shí),在滿足國(guó)際室內(nèi)照明標(biāo)準(zhǔn)的前提下,在距離屋頂2.25 m的4 m×4 m接收平面上光照度分布最均勻,其均勻度達(dá)到90.4%。該光源列陣布局模型可推廣到任意尺寸房間,為室內(nèi)辦公照明中光源的布局提供了一種可行的方案。
[Abstract]:In the visible light communication system, the light source has the dual function of lighting and communication. Because the room size and indoor environment are different, it is inevitable that there are places where the light can not be illuminated or the light is weak.These places are likely to be the blind areas of communication, which will greatly affect the quality of communication. In order to solve the shadow effect, it is necessary to reasonably design the light source, taking 4 m 脳 4 m 脳 3 m room as the model and using four LED arrays as the indoor light source.Taking a single LED source as a Lambert light source and applying the Lambert radiation model, a 9 脳 9 size LED array with a spacing of 0.03 m from the edge of the roof is obtained by formula calculation and software simulation analysis.On the premise of meeting the international indoor lighting standard, the light intensity distribution is the most uniform on the receiving plane of 4 m 脳 4 m from the roof 2.25 m, and the uniformity reaches 90.4%.The light source array layout model can be extended to any size room, which provides a feasible scheme for the layout of light source in indoor office lighting.
