Abstract
The present invention relates to an indoor parking lot, comprising: a hollow frame portion, which is installed in the lengthwise direction on the ceiling along a driving path; and a lighting portion, which is fixedly installed on a side surface of the frame portion, for lighting the driving path and parking space around the driving path, wherein the lighting portion provides light distribution which is perpendicular to a driving direction of the driving path. The present invention is installed along the driving path of a vehicle which is between the parking spaces, so as to limit light distribution to directions on both sides of the direction of installation, thereby reducing the number of lighting portions while providing light having ample brightness to the parking spaces and a lighting space and thus effectively minimizing power consumption despite constant lighting.
