Dimmer with mode switching switch circuit

Abstract

To provide a dimmer device including a switch circuit capable of increasing versatility in addition to fixed switch operation; i.e., when there are two or more user switches, the switch operation is restricted to only one user switch, or depending on the case, either switch operation can be switched between transparent and opaque states.SOLUTION: The dimmer device has a switch circuit that includes: a light control film that includes a light control body capable of controlling light by voltage application; a power supply unit; and a switch for switching between transparent and opaque states. The switch circuit includes at least two user switches and a DIP switch for switching a mode of user switch operation.SELECTED DRAWING: Figure 1

Claims

1. A dimmable film equipped with a dimming element that can be dimmed by applying voltage, a power supply, and a switch circuit including a switch for switching between a transparent state and an opaque state of the dimmable film, comprising at least two user switches and a DIP switch for switching the mode of the user switches, The switch circuit switches the state of the dimming film between the transparent state and the opaque state by switching between applying and not applying voltage to the dimming element. The two user switches consist of a first switch and a second switch. The mode of the user switch is, A mode in which the voltage is applied to the dimmer only when both of the user switches are turned on. A mode in which the application and non-application of the voltage to the dimming element can be switched by operating each user switch, A mode in which only the operation of the first switch can switch between applying and not applying the voltage to the dimmer, A mode in which only the operation of the second switch can switch between applying and not applying the voltage to the dimmer, A mode in which the state in which the voltage is applied to the dimming element is maintained regardless of whether each user switch is operated, and This consists of a mode in which the state in which the voltage is not applied to the dimmer is maintained regardless of whether each user switch is operated or not. A dimming device characterized by the following features.

2. The dimming device according to claim 1, characterized in that the dimming film becomes transparent when both of the user switches are set to the ON position.
