Embodiment approach 1

[0041] The first embodiment of the present invention provides a lighting fixture, which is powered by the mains, see figure 1 shown, including:

[0042] Lamp switch, used to control the mains input of lighting fixtures;

[0043] The power conversion circuit is electrically connected with the lamp switch, and is used to convert the input power of the mains into the output power for supplying power to the load;

[0044] The power monitoring circuit is electrically connected to the lamp switch, and is used to monitor whether the lamp is powered on;

[0045] The load regulation circuit is electrically connected with the power monitoring circuit and the power conversion circuit, and communicated with the external operation port, and is used to control the output characteristics of the power conversion circuit according to the load regulation signal sent by the external operation port;

[0046] When the power supply monitoring circuit detects that the lamp switch lights up the lig...

Embodiment approach 2

[0053] The second embodiment of the present invention provides a lighting fixture, and the second embodiment is a further improvement of the first embodiment; the main improvement is that in the second embodiment of the present invention, see figure 2 As shown, the load regulation loop consists of:

[0054] The receiver is used to receive the load regulation signal sent by the external operation port;

[0055] The MCU unit is electrically connected with the power monitoring circuit, the receiver and the power conversion circuit, and is used to send a PWM signal to the power conversion circuit according to the load adjustment signal received by the receiver;

[0056] The MCU unit does not respond to the received load adjustment signal within a preset time after receiving the power-on reminder signal.

[0057] Using the receiver to receive the load regulation signal sent from the external operation port has the advantage of convenient operation, and using the MCU unit to control...

Embodiment approach 3

[0061] The third embodiment of the present invention provides a lighting fixture, and the third embodiment is a further improvement of the first or second embodiment; the main improvement is that in the third embodiment of the present invention, see image 3 As shown, the power conversion circuit includes: Buck circuit;

[0062] The MCU unit is electrically connected to the Buck loop, and the Buck loop adjusts the load of the lighting fixture according to the received PWM signal.

[0063] The load connected to the Buck loop can be effectively and conveniently controlled by the PWM signal sent by the MCU unit.

Abstract

The invention relates to the field of household electrical appliances, and discloses a lighting fixture and a control method for the lighting fixture. The lighting fixture is powered by commercial power, comprising: a lighting switch; a power conversion circuit; a power monitoring circuit; a load regulation circuit; When the lighting fixture is turned on, a power-on reminder signal is sent to the load regulation circuit, and the load regulation circuit does not respond to the received load regulation signal within a preset time after receiving the power-on reminder signal. A lighting fixture using a lighting fixture control method can prevent loop problems caused by momentary load fluctuations.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a lighting fixture and a control method for the lighting fixture. Background technique [0002] With the popularity of smart homes, intelligent control of lighting fixtures has gradually become a new trend. In the current lighting fixtures, for the convenience of use, a function of one-key lifting to the maximum load is often provided. [0003] Conventional LED circuits are usually composed of two parts of the circuit, one of which is a power conversion circuit, which is used to convert the connected mains power into a power supply suitable for the load of the lighting fixture, and the other part of the circuit is a load regulation circuit. It is used to control the power conversion circuit to adjust the output status of the load such as brightness, color temperature or number of lights. [0004] When the power supply is just powered on, the power conversion circuit has not ...
