The invention has an object of obtaining an illuminating panel by which an illuminated area having a high illuminance and a stable flat illuminance distribution can be formed with a long irradiation distance while power is being saved. An illuminating panel 100 has disposed thereon a plurality of linear light source units 200, and the linear light source units 200 each include: a light emitter having a plurality of light emitting diodes linearly installed on a base; a first reflector formed of parabolic surfaces which are provided on a light emergence side of the light emitter in such a way as to correspond to the plurality of light emitting diodes, and light emitting faces of which fall in focal positions; and a second reflector having a pair of flat plate-like reflecting surfaces which, being arranged with the light emitting diodes sandwiched therebetween, farther to the light emergence side than the first reflector and parallel to an array direction of the light emitting diodes, reflect light from the light emitting diodes toward the light emergence side, wherein the linear light source units 200 are annularly disposed on a module panel. |
