Abstract
A method for adjusting the brightness of a light source is performed according to the status of input voltage which is determined by detecting how and how many times a toggle switch switches state. When a user switches the state of the toggle switch for the first time in order to turn on/off the light, the brightness of the light source gradually increases/decreases within a dimmer period, during which the user may select an appropriate brightness of the light source by giving a swift double-toggle on the toggle switch.
Claims8
A method for adjusting a brightness of a light source using a toggle switch, the method comprising:
- identifying a first state of the toggle switch when the light source is in an initial state;
- gradually adjusting the brightness of the light source from a first brightness to a second brightness during a dimmer period after the toggle switch changes from the first state to a second state at a first time point;
- and
- maintaining the brightness of the light source at the value obtained from a second time point when the toggle switch changes from the second state to the first state at the second time point and then changes from the first state to the second state at a third time point, wherein a first dimmer period from the second time point to the third time point does not exceed a turn-off time of the light source.
