| 摘要 |
The present invention relates to a method for illuminating a space, and more specifically, to a method for illuminating a space using a plurality of LED illumination modules, wherein the plurality of LED illumination modules adjust a mutual distribution ratio between a vertical illuminance and a horizontal illuminance, which is greater than the vertical illumination, according to a limitation of a radiation angle at one point within the space having the constant volume. The present invention can increase the efficiency of illumination and can reduce electric energy by lowering the vertical illuminance compared to the horizontal illuminance. |
