Abstract
A transmittance of light is adjusted by more various operation modes compared to the related art. In a dimming device, in a case where an AC voltage having a first frequency and an amplitude equal to or greater than a first amplitude is applied, the transmittance of light in the first wavelength range is higher than that in a case where a flake is oriented in a direction shielding the light, and in a case where an AC voltage having a second frequency and an amplitude equal to or greater than a second amplitude is applied, the transmittance of light in the second wavelength range is higher than that in a case where a flake is oriented in a direction shielding the light. Here, the second amplitude is equal to or greater than the first amplitude.
Claims11
A dimming device that adjusts a transmittance of light by controlling an orientation of a dimming member, the device comprising:
- a first dimming member that changes the transmittance of the light in a first wavelength range in accordance with a change in an orientation state;
- and
- a second dimming member that changes the transmittance of the light in a second wavelength range in accordance with the change in the orientation state,
- wherein, in a case where an AC voltage having a first frequency and an amplitude equal to or greater than a first amplitude is applied, the transmittance of the light in the first wavelength range is higher than that in a case where the first dimming member is oriented in a direction shielding the light,
- in a case where an AC voltage having a second frequency and an amplitude equal to or greater than a second amplitude is applied, the transmittance of the light in the second wavelength range is higher than that in a case where the second dimming member is oriented in a direction shielding the light, and
- the second amplitude is equal to or greater than the first amplitude.
