Control device with light adjustment function
First Claim
1. A control device with a light-adjustment function coupled between a power supply and a lighting load, comprising:
- a first switch coupled to the power supply, wherein when the first switch is turned on by a user, a power signal generated by the power supply is transmitted to the lighting load via the first switch, and the brightness of the lighting load is gradually increased or reduced as time increases;
a timing setting switch configured to set a time value by the user independently of the first switch;
a control unit coupled to the timing setting switch, wherein when the first switch is turned on, the control unit executes a countdown according to the time value during which time the brightness of the lighting load is gradually increased or reduced, and upon finishing the countdown, the control unit generates a trigger signal and simultaneously the brightness of the lighting load is at a set value; and
a second switch coupled between the control unit, the first switch and the lighting load, wherein when the second switch receives the trigger signal, the second switch automatically stops transmitting the power signal from the first switch to the lighting load, and then immediately transmits the power signal from the first switch to the lighting load such that the brightness of the lighting load is at the set value.

Abstract
A control device including a first switch, a control unit and a second switch is provided. When the first switch is turned on, a power signal generated by a power supply is transmitted to a lighting load via the first switch. The brightness of the lighting load is gradually increased or reduced as time increases. When the first switch is turned on, the control unit executes a countdown according to a time value. Upon finishing the countdown, the control unit generates a trigger signal and simultaneously the brightness of the lighting load is at a set value. When receiving the trigger signal, the second switch stops transmitting the power signal from the first switch to the lighting load at first and then transmits the power signal from the first switch to the lighting load such that the brightness of the lighting load keeps at the set value.
