“…In order to attain more effective use of dynamic daylight, stable optical components and active devices of the daylighting system were studied. Common optical components are high-reflectivity light pipes [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31], Fresnel lens [32][33][34][35][36][37][38][39][40][41][42][43][44], linear Fresnel lens [45][46][47], optical fiber with different materials [32], light guide [39], parabolic concentrator [48][49][50], Compound Parabolic Concentrator (CPC) [38,47,51,52], dish concentrator [1,53], cold mirror [48], IR filer [32,38], hot mirror [49] and prism structure ...…”
