The present invention relates to the technical field of lighting equipment, particularly to a power regulating device.
Background Power regulating of lights is usually realized with a dedicated dimmer, such as 0-10V dimmer, controllable silicon dimmer, etc. Such dimmers are usually independent from the light, and the specification of the dimmer should match the specification of the driving power supply inside the light, so that the dimmer can be used. The operation of such application is complex. Also, when the specification of the dimmer does not match that of the driving power supply, the circuit is easy to burn out, and accidents will occur. Additionally, existing lights usually apply continuous power regulating which is hard to realize precise dimming of specific power and affects the service effect.

Taking the light with the maximum power of 63 W as an example, the light body is provided with a power regulating device. The power regulating device comprises a rotatable regulating part, a potentiometer, at least one control switch and one control power supply. The regulating part comprises the first regulating section and the second regulating section. The first regulating section connects to the potentiometer (variable resistance RT1), and can change the resistance value of the potentiometer during rotation of the regulating part to generate continuously changing first control signals, enabling the control power supply to realize corresponding continuous power output. During rotation of the regulating part, the second regulating section can gradually start one or multiple control switch/es to change the state of the control switch and generate specific second control signals, enabling the control power supply to realize specific precise power output [in the embodiment, the control switch can be normally open, when the second regulating section contacts the control switch, the switch will be turned off to send the second control signals to the control power supply; when the second regulating section does not contact the control switch, the switch will be turned off automatically, so that the second control signals will not be sent]. For example, when the second regulating section rotates to the first control switch SW1, one second control signal enabling output of 36 W power will be sent to the control power supply, when the second regulating section rotates to and contacts the second control switch SW2, another second control signal enabling output of 54 W power will be sent to the control power supply (

(3) Multiple specific power points for precise dimming can be added, the power regulating precision is high, and the working stability of lights can be improved.
(4) This facilitates unification of the light specification. Users only need to buy one specification of products. By regulating the dimming device manually, the power demands of different lighting scenes can be met. Users can freely select brighter or more energy-saving working models according to personal likes. No matter the light is supplied with electricity, the power can be adjusted, enabling convenient and safe operation.
