Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution:

example 1: the utility model provides an intelligent dimming controller circuit of multiple control mode, includes switch box (1) and rotary switch 2, is provided with rotary switch (2) on the switch box 1, is provided with integrated circuit board, three functional module in the switch box 1: the power management module, the control circuit and the simulation phase-cut control circuit are matched with each other to form an intelligent dimming control circuit which can be controlled by a mechanical switch and can also be controlled by intelligent equipment in multiple control modes. As shown in fig. 1, when the smart dimmer is connected to the commercial power 220VAC at the input terminal L \ N and the LED lamp is connected between the output terminal N1 and the DIM, the circuit starts to enter the working state. At this time, the "power management module" starts to work, and forms a half-bridge rectification circuit through the diode D6 shown in fig. 2, and then passes through a DC to DC BUCK power management chip, so that a stable constant voltage output voltage DC-5V can be finally output. The power management module shown in fig. 2 provides stable direct current 5V power supply for the control circuit and the analog phase-cut control circuit. Referring to fig. 1 and 3, when the "power management module" in fig. 2 provides stable power for the "control circuit" in fig. 3, after passing through the U4 linear regulator module shown in fig. 3, a dc 3.3V voltage is output from the U4, so as to provide a normal operating voltage for the Model 1-wireless control module and the U5-programmable integrated circuit; in the initial state, the pin P0.4 of the LS1-LED lamp is set to be in a high level by U5, at the moment, the optocoupler U2 is enabled to conduct work, the U2 is enabled to conduct work, Q2 is enabled to conduct work, the control voltage of Q1 is pulled down, and Q1 is enabled to be turned off, so that the LS1-LED lamp is in a turned-off state. And the Model1 wireless control module also enters into working state, and at this time, the dimmer can be connected to the mobile phone APP wirelessly through the intelligent device (mobile phone APP and the like). As shown in fig. 1 and 4, when power is just turned on, the optocoupler U1 is periodically conducted with the mains supply through the voltage reduction resistors R1 and R2 between L and N, the mains supply periodic signal is sent to the P1.0 port of U5 through U1, and when an action of dimming control needs to be generated, the U5 judges which time slot the phase-cut power switch Q1 needs to be controlled through a signal received from U1. Through the U3 DC-DC voltage conversion module, the 5V direct current voltage of the power management module is increased to the working voltage 15V required by the Q1, and the conduction working voltage is provided for the Q1.

The internal connection of the knob type mechanical regulating switch is that a pin 1 of SW is connected with a pin P1.2 of U5, a pin 3 of SW is connected with signal ground, a pin 6 is connected with a pin P1.3 of U5, and a pin 4 of SW is connected with a pin P1.4 of U5. When the switch is pressed, the 1 pin and the 3 pin of the SW are communicated; when the adjusting switch of the SW is rotated clockwise, the 6 feet of the SW and the 4 feet of the SW are communicated with the 3 feet in sequence; when the adjusting switch of the SW is rotated in a counterclockwise mode, the 4 pins of the SW and the 6 pins of the SW are communicated with the 3 pins in sequence. When the knob type mechanical adjustment switch is used for operation, when the switch SW is pressed, the pin SW1 is communicated with the pin 3, and the pin P1.2 of U5 detects a low-level signal at the moment and judges that the switch acts at the moment; when the U5 detects low level information for the first time through the P1.2 pin, the U5 changes the output signal of the P0.4 pin to enable the P0.4 pin to output low level, so that the optocoupler U2 is turned off, and the rear-end triode Q2 is turned off; after Q2 is turned off, Q1 provides normal operating voltage from U3 through R5 and R6, and Q1 is turned on. Q1 causes current to flow from the L port into the LS1 and then from the DIM terminal through the LS1-LED back to the N1 terminal, and the LED lamp is normally lighted. When the switch SW is pressed again, after the U5 detects the low level signal of the P1.2 pin again, the U5 changes the output state of the P0.4 pin from the last low level to the high voltage, so that the U2 is turned on again, and the Q2 is turned on, and when the Q2 is turned on, the Q1 driving level is pulled down, so that the Q1 is turned off, and the LS1-LED lamp is turned off. When the U5 detects a low signal of the P1.2 pin each time, the output state of the P0.4 pin will be changed (high-low electrical cycle change).

When the LS1-LED lamp is turned on and the knob of the knob type mechanical adjusting switch SW is used for adjusting, the U5 detects the level states of the 6 pin and the 4 pin of the SW and the level states of the P1.3 pin and the P1.4 pin respectively; when the knob direction is clockwise, the pin P1.3 will detect the conducted low level signal first, and then the pin P1.4 will detect the low level signal, at this time, the U5 detects the clockwise rotation information through two conducting sequences; the U5 will gradually increase the low level output period of P0.4 pin, finally the on time of Q1 in the whole period is increased, and the brightness of LS1-LED is increased; when the direction of the turn button of the SW is a counterclockwise direction, the pin P1.4 will detect the on low level signal first, and then the pin P1.3 detects the low level signal, at this time, the U5 detects counterclockwise rotation information through two on sequences; the U5 will gradually reduce the low output period of the P0.4 pin, eventually reducing the on-time of Q1 in the whole period, and reducing the brightness of the LS 1-LED.

When the dimmer is controlled by using a smart device instead of the knob-type mechanical adjustment switch, the smart device such as a mobile phone performs information transmission with the Model 1-wireless control module through wireless communication. When the wireless control module Model1 receives the control signal of the intelligent device, the control signal is transmitted to the pins P0.6 and P0.7 of the U5 through the information transmission ports of the PWM1 and the PWM2 of the Model 1; and after receiving signals of the P0.6 pin and the P0.7 pin, the U5 controls the working states of the dimmer and the LS1-LED lamp through the P0.4 pin, so that the functions of dimming and switching are realized.

When the intelligent equipment and the knob type mechanical adjusting switch SW are operated simultaneously, when the U5 detects the working level changes of the pins P1.2, P1.3 and P1.4, the communication processing between the intelligent equipment and the Model1 is shielded; when the U5 detects a switch signal of the knob type mechanical adjusting switch SW, the signal of the SW is processed preferentially, and the control signal of the Model 1-wireless control module is processed when the signal of the SW does not exist, so that the stable dimming performance can be realized, and the problems of poor dimming effect and flicker during dimming of the traditional dimmer are avoided. The function of compatible regulation of mechanical type regulating switch and intelligent control equipment can be realized.

Example 2: the components of the power management module can be composed of other rectification modules, and the half-bridge rectification structure of D6 can be changed into a full-bridge rectification structure; the BUCK type topology formed by the U7 can be changed into other power management ICs of the same type; the Model1 is a wireless control module, which can realize wireless communication by a bluetooth wireless module, a WIFI module or a ZIGBEE module.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
