ILLUMINATION LIGHT DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an illumination light display device with high visibility so that an indicator applied for a management system of a picking facility can easily and visually confirm the illumination state of a light guide plate even at an installation place out of view height.

SOLUTION: This illumination light display device is constituted by an assembly of: the rectangular light guide plate 10 using as an illumination light surface a front side 11, and edge end surfaces 12 on the upper side and lower side; light emitting diode (LED) modules 20 which have a plurality of LEDs 22 arranged in an array form on a circuit substrate using the light guide plate 10 as an illumination light source and are oppositely arranged on side edge end surfaces 13, 14 of the light guide plate; and a case 30 which accommodates the LED modules 20 and makes a recessed frame structure surrounding the peripheral part of the light guide plate 10 except for the illumination light surface and shielding light to the space to the periphery.
