Abstract

PROBLEM TO BE SOLVED: To eliminate irregularity in illumination over the entire pilot lamp light emission surface in mutually continuous directions by arranging a diffusion sheet which makes an LED illuminate uniformly over the entire LED light emission surface between the LED and an LED cover. SOLUTION: The diffusion sheet 13 is mounted on a printed board 12 in the front of the LED 11 so that the entire LED light emission surface 11a of the LED 11 illuminates uniformly. In this constitution, the light emitted by the LED 11 impinges on the diffusion sheet 13 to cause surface light emission along the surface of this diffusion sheet 13 and then the light emitted by the LED 11 is uniformly diffused and projected to prevent the pilot lamp light emission surface 16 from having irregularity in illumination. Consequently, when the LED 11 illuminates, the pilot lamp light emission surface 16 of the LED cover 14 illuminates and is continuous to the front and flank of a case main body 15, so the illumination of the pilot lamp can be confirmed from places over a wide range.

However, the above-mentioned conventional LED display light device emits light emitted from the LED 31 to the display light emitting surface 36 of the milky white LED cover 34.
Since the light emitted from the LED 31 has directionality, the light emitted to the outside is emitted from only one of the misalignment of the indicator light emitting surfaces 36 and 37 because the light emitted from the LED 31 has directivity. As a result, the other indicator light emitting surface will have uneven light, and in electrical equipment using such an indicator light device, such as a nurse call corridor, if it does not move to the light emitting direction position, the display is performed. The inconvenience of not being able to confirm was imposed.
