This study proposed a model with different luminous intensity profiles without reflective matrix bar for light fixtures that used asymmetric luminous intensity(ALI) CSP-LEDs (Chip Scale Package-Light emitting diode) combined with light guide as light source module. and analyzed illumination uniformity and unified glare rating (UGR) performance by using a classroom as an example.
