PROBLEM TO BE SOLVED: To provide a display system which is used for guide displays in buildings, signs in parks, etc., and can make sufficient display by a small number of light emitting diodes without decreasing a light quantity. SOLUTION: The display system 1a is used for the emergency guide sign installed in the park and has the light emitting diodes 2g and 2o which are light sources, an escape sign 3a and arrow 3b as objects 3 to be irradiated which are irradiated by the light emitting diodes 2g and 2o and a power source device 4 which is a power source. The distances, at which the irradiation range of the light of the light emitting diodes 2g and 2o spreads and the entire part of the escape sign 3a and the arrow 3b is irradiated, are disposed between the light emitting diodes 2g and 2o and the escape sign 3a and the arrow 3b. Since screens, etc., for diffusing the light are not disposed between both, there is no decrease in the light quantity and therefore the irradiation of the objects 3 to be irradiated may be executed by a small number of the light emitting diodes 2. |
