不便を強いていた。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.
