To provide a lighting system capable of preventing the glare from being intolerable irrespective of a viewing direction, and capable of suppressing the occurrence of failure caused by a warping of a chassis from occurring.
In an LED fixture 10, a pair of LED units 50 having a plurality of LEDs 55 which are disposed in line, and printed wiring to electrically connect the LEDs 55 to emit light are accommodated in both sides of a light emitting space J along a side forming a flat rectangular shape of the light emitting space J, and a light emitting side of each of the LED units 50 is sheathed by a diffusion cover 60 along the line of the LEDs 55 for each of the LED units 50. Thereby, the output light output from the plurality of LEDs 55 is diffused by a diffusion cover 60, and radiated toward the outside in a flat shape, so that even when the LEDs 55 of the LED units 50 are seen from a front according to the viewing direction, the output light output from the LEDs 55 does not directly come into view so as to become a tempered light.
