Abstract
A light-emitting apparatus applied with a power switch includes a light-emitting unit and a dimming driving unit. The light-emitting unit has at least one light-emitting element. The dimming driving unit is electrically connected with the light-emitting unit and controls the light-emitting element to emit a first brightness or a second brightness, which are both nonzero, according to a switching frequency or a switching interval of the power switch during a specific time range when the power switch is turned on.

A light-emitting apparatus applied with a power switch, comprising:
- a light-emitting unit having at least one light-emitting element;
- and
- a dimming driving unit electrically connected to the light-emitting unit and controlling the light-emitting unit to emit a first brightness or a second brightness according to a switching frequency or a switching interval of the power switch during a specific time range when the power switch is turned on, wherein the first brightness and the second brightness are both nonzero.
A light-emitting apparatus, comprising:
- a light-emitting unit having at least one light-emitting element;
- and
- a dimming driving unit electrically connected to the light-emitting unit and controlling the light-emitting element to emit a first brightness or a second brightness according to a frequency or an interval of receiving an external power signal during a specific time range when the dimming driving unit receives the external power signal, wherein the first brightness and the second brightness are both nonzero.
A dimming method, comprising the steps of:
- electrically connecting a light-emitting unit and a dimming driving unit, the light-emitting unit having at least one light-emitting element;
- and
- controlling the light-emitting element to emit a first brightness or a second brightness by the dimming driving unit according to a frequency or an interval of receiving an external power signal during a specific time range when the dimming driving unit receives the external power signal, wherein the first brightness and the second brightness are both nonzero.
