Detailed Description
the invention uses a microcontroller (MCU control circuit) to generate PWM signals with different duty ratios, thereby realizing the adjustment of the output light of the LED primary and secondary lighting equipment. When receiving the detection information result corresponding to the set control mode, the MCU control circuit generates a PWM signal according to the corresponding dimming requirement, and sends the PWM signal to the TRIAC circuit, and the TRIAC circuit is used for dimming the submachine in the mother lighting device. The input voltage value of the submachine obtained by the AC power supply is determined by the conduction time of the TRIAC circuit, the effective input voltage is increased if the conduction time is long, and the effective input voltage is decreased if the conduction time is short, so that the aim of adjusting the brightness of the lamp is fulfilled by using the change of the voltage.

The secondary machine is arranged in a living room or a main bedroom, and the primary machine is arranged at a position different from the position where the secondary machine is arranged, such as a door or a house.
Fig. 2 is a schematic view of the structure of the detecting unit 6 in fig. 1.
as shown in fig. 2, the detection unit 6 includes a human body sensor 9, a light intensity sensor 10, and a rotary switch 11, and the detection unit 6 can be used to detect human body movement and light intensity information around the mother machine.
the human body sensor 9 is used for detecting and sensing human body activity information, the illuminance sensor 10 senses the intensity of ambient light to perform illuminance detection to judge the intensity of ambient light, and the detected human body activity information and the ambient light intensity information are used as the basis for dimming the sub-machine.
The user selects a control mode through a preset setting position of the rotary switch 11, and in combination with the human body sensor 9 and/or the illuminance sensor 10 in the detection part 6, the MCU control circuit 5 sends preset PWM signals with different duty ratios to the TRIAC circuit 4 according to the human body activity information and/or the ambient light intensity information detected by the detection part 6, controls the sub-lamps to act according to the preset corresponding control mode, and lights on, lights off and/or dims, can set continuous lighting time, and realizes richer segmented dimming. The continuous lighting time is preset by preset software. The rotary switch 11 may be replaced by a touch panel or a selection button.
In a preferred embodiment, the body sensor 9 is an infrared sensor, which uses thermal infrared radiation generated by a human to generate an electrical signal.
As shown in fig. 1 and 2, the detection unit 6 transmits the human body movement information detected by the human body sensor 9, the ambient light intensity information detected by the illuminance sensor 10, and the setting mode (setting position) of the rotary switch 11 to the MCU control circuit 5. The MCU control circuit 5 transmits a PWM (pulse width modulation) signal to the TRIAC circuit 4 according to the human body activity information and/or the ambient light intensity information transmitted from the detection unit 6 in combination with the setting mode of the rotary switch 11, so that the TRIAC circuit 4 performs ON/OFF operation, thereby realizing dimming control of the handset 3. Therefore, the sub-unit can be appropriately dimmed according to the detected external lumen value and the human body activity information, and the output of the sub-unit is reduced.
The MCU control circuit 5 further sends a master control signal corresponding to the detection information to a master power control circuit (not shown), and adjusts the master according to the master control signal.
Dimming to the submachine includes: and at least one of lighting the submachine, extinguishing the submachine, adjusting the brightness of the submachine and controlling the lighting time of the submachine is operated.
Dimming of a master comprising: and at least one operation of lighting the main machine, extinguishing the main machine, adjusting the brightness of the main machine and controlling the lighting time of the main machine.
In a preferred embodiment, the sub-machine is a lamp in a phase dimming mode. When the TRIAC circuit 4 performs the ON/OFF operation, the slave unit is turned ON with dimming, i.e., the luminance is reduced to 25%, for example, and when the TRIAC circuit 4 maintains the ON operation, the slave unit is turned ON with 100% FULL, and when the TRIAC circuit 4 maintains the OFF state, the slave unit is in the OFF state. Of course, a single ON/OFF type lamp may be selected as the slave lamp.
Fig. 3(a) shows a voltage waveform applied to a slave unit in a conventional slave lighting device.
as shown in fig. 3(a), the MCU control circuit outputs an ON/OFF signal to the TRIAC circuit, and in the ON signal control state, the AC power supplies a complete AC power to the slave unit through the TRIAC circuit, so that the brightness of the slave unit is 100%, and in the OFF signal control state, the TRIAC circuit is OFF, so that the AC power does not supply a voltage to the slave unit, so that the slave unit is in the OFF state, and the brightness is 0%.
Fig. 3(b) is a voltage waveform applied to the slave unit based on the PWM control in the child-mother lighting apparatus according to the present invention.
First, in the first stage, the MCU control circuit 5 does not output the PWM control signal pulse, which is the same as the part shown in fig. 3(a), and is not described herein again.
In the second phase, the MCU control circuit 5 outputs a series of pulses of the PWM control signal, which are used to control the TRIAC circuit 4. The PWM control signal pulses with different cycle ratios can lead the conduction time lengths of the TRIAC circuit 4 to be different, thereby leading the effective values of the voltages applied to the submachine by the AC power supply 1 to be different, and realizing the dimming of the submachine. In other words, the width of the control signal pulse is modulated so that the TRIAC circuit 4 adjusts the conduction angle (ON period) to change the magnitude of the effective voltage value applied to the slave unit, thereby changing the luminance of the slave unit and realizing richer dimming in stages.
According to a preferred embodiment of the present invention, the lighting device is a sub-lighting device, and the sub-lighting device is mainly used for implementing segmented dimming, such as lighting only 25% or 30%. More segment dimming can be provided while ensuring the operation of the TRIAC circuit 4.
When the human body sensor 9 in the detection part 6 detects that a person exists, the MCU control circuit 5 can give a low level signal to turn on all lights of the sub-machine, and when the presence of a person is not detected and a certain preset condition is satisfied, the MCU control circuit 5 gives a PWM signal to perform a step dimming, for example, only turn on 25%. When the MCU control circuit 5 gives a high level signal, the sub-machine is turned off.
The MCU control circuit 5 can perform a stepwise dimming operation based on the ambient light intensity information detected by the illuminance sensor 10 in the detection unit 6. For example, when it is detected that the ambient light is dark (for example, the ambient brightness is less than 5 lx), the PWM signal sent by the MCU control circuit 5 to the TRIAC circuit 4 has a duty ratio of 40%. When it is detected that the ambient light is dark (for example, the ambient brightness is greater than 25 lx), the MCU control circuit 5 sends the PWM signal to the TRIAC circuit 4 with a duty ratio of 25%.
in combination with the human body sensor 9 and the illuminance sensor 10 in the detection portion 6, the MCU control circuit 5 can realize the step dimming according to the human body activity information and the ambient light intensity information detected by the detection portion 6. For example, when a person is detected and the ambient brightness is detected to be 50lx, the PWM signal transmitted from the MCU control circuit 5 to the TRIAC circuit 4 has a duty ratio of 40%. When the ambient brightness is detected to be 100lx, the PWM signal sent by the MCU control circuit 5 to the TRIAC circuit 4 has a duty ratio of 25%.
Fig. 4(a) and 4(b) are schematic diagrams of two dimming level examples of the slave unit multi-step dimming. As shown in fig. 4(a) and 4(b), the voltage waveform of the slave unit differs depending on the PWM control signal transmitted from the MCU control circuit 5 to the TRIAC circuit 4, and different dimming levels can be generated.
Preferably, the MCU control circuit 5 also sends a PWM master control signal corresponding to the detection information to a master power control circuit (not shown), and adjusts the master according to the master control signal.
In the invention, for the slave machine, the MCU control circuit 5 sends PWM signals with different cycle ratios to the TRIAC circuit 4 to ensure that the conduction time lengths of the TRIAC circuit 4 are different, thereby realizing phase dimming, and the master machine realizes the master machine dimming by sending the PWM signals to the master machine power supply control circuit. In this case, the duty ratios of the PWM signals transmitted to the slave unit and the master unit may be different from each other, and may be set based on the FULL lighting current and the step dimming current.
Specifically, for example, the control port of the master device is 17pin, the control port of the slave device is 22pin, the MCU control circuit 5 transmits PWM signals to the control port of 17pin and the control port of 22pin, respectively, and the PWM signal transmitted to the control port of 17pin is different from the PWM signal transmitted to the control port of 22 pin. For example, the duty ratio of the two is different because, for example, in the full lighting mode, the current of the master unit is 200mA, and the current of the slave unit is 160mA, and the PWM signals of the master unit and the slave unit need to be different to satisfy the respective dimming characteristics.
The "control mode" according to the present invention is described below with reference to table 1.
in table 1, 9 control modes in total, i.e., modes 0 to 8, are listed, and when a user selects a certain mode by adjusting the position of the rotary switch 11, whether the mode belongs to the "welcome-to-home mode" is selected according to the corresponding condition in the mode listed in table 1, and if the mode belongs to the "welcome-to-home mode", the preset duration of the welcome-to-home mode corresponds to the duration of the mode. Then, the lighting device controls the sub-lamps to turn on, turn off, and/or dim the light by sending PWM signals with different duty ratios to the TRIAC circuit 4 based on the selected control mode in combination with the human activity information and/or the ambient light intensity information detected by the human body sensor 9 and/or the illuminance sensor 10.
in the case that the duration of the "welcome home mode" is 4 hours, as shown in control mode 1, it means that the primary and secondary lighting devices will operate in the "welcome home mode" 4 hours after the system-preset home time (for example, 8 o 'clock in the evening) is selected by the user, that is, until 12 o' clock in the evening.
In table 1, the "leaving mode" in the control mode 8 means that when the user leaves home, i.e., when the user knows that he does not get home at night or within a certain number of days, and does not want the slave unit to be turned on by itself according to the detection result by setting of another control mode during leaving home, the "leaving mode" is selected so that the MCU control circuit 5 ignores the detected illuminance information and the human body movement information, and the master lamp and the slave lamp are always kept off and are not turned on by the detection result from the detection unit.
In addition, although not shown in table 1, in a preferred embodiment, another "leaving mode" may be included, in which the system is preset with a leaving time, for example, 8 o 'clock in the morning of working day, and in the case that the "leaving mode" is set to 9 hours, the primary and secondary lighting devices are operated in the "leaving mode" until 5 o' clock in the evening. In this "away mode", since the detected illuminance information and the human body movement information are set so as not to be ignored, even when the light is temporarily turned dark due to a cloudy day or other conditions easily cause erroneous detection of the human body movement information, the sub lamp and the main lamp are not turned on by the detection results. But instead will go to the normal "welcome home" mode or other mode after a specified 9 hours has elapsed.
At least one control mode in the present invention may be: detecting environment light intensity information and whether human activity information exists, comparing the environment light intensity information with a preset light threshold value by the MCU control circuit, if the human activity information is detected, and the environment light intensity information is in the set light threshold value, adjusting a PWM (pulse width modulation) value by the MCU control circuit according to preset information, sending a sub machine control signal corresponding to the detection information to the TRIAC circuit, controlling a sub machine to light corresponding preset brightness and preset duration, and if the environment light intensity information is greater than the set light threshold value, not lighting the sub machine.
in addition, at least one control mode of the present invention may be: detecting ambient light intensity information, comparing the ambient light intensity information with a preset light threshold value by the MCU control circuit, and if the ambient light intensity information value is within the set light threshold value, adjusting a PWM (pulse width modulation) value according to preset information by the MCU control circuit, sending a sub machine control signal corresponding to the detection information to the TRIAC circuit, controlling a sub machine to light corresponding preset brightness and preset duration, and if the ambient light intensity value is greater than the set light threshold value, not lighting the sub machine.
In addition, the at least one control mode may be: and detecting whether human body activity information exists or not, and if the human body activity information is detected, adjusting the PWM value by the MCU control circuit according to preset information, sending a submachine control signal corresponding to the detection information to the TRIAC circuit, and controlling the submachine to light corresponding preset brightness and preset duration.
Table 1 is an embodiment of a sub-lamp intelligent control setting mode having a welcome home mode and a away home mode.
As shown in table 1, according to the preset 9-step setting position of the rotary switch 11, in combination with the brightness of the ambient light intensity information and whether the human body sensor 9 detects human body activity information, the primary and secondary lighting device of the present invention has the following control modes:
Control mode 0: the "welcome home mode" is not included in this control mode. When the position selected by the rotary switch 11 is "0", at this time, if the human body sensor 9 detects the human body activity information and the ambient light intensity information is less than 5lx, the MCU control circuit 5 gives a low level signal, the master and the linked slave are both turned ON at 100%, and after the lighting is maintained (ON) for 1 minute, if the human body activity information cannot be detected, the master and the linked slave are both turned OFF (OFF). Since the motion sensor 9 continuously detects the presence or absence of the motion information, the master unit and the linked slave units continue to be lit at 100% for 1 minute if the motion information is still detected after the master unit and the linked slave units are kept lit at 100% for 1 minute. This is repeated until the master unit and the slave units linked with each other are turned OFF (OFF) when the human body movement information cannot be detected after the lighting is maintained at 100% for 1 minute. The extinguished primary and secondary lighting device can be turned on again by 100 percent when the human body sensor 9 detects the human body activity information again.
If the human body sensor 9 detects human body activity information but the ambient light intensity information is more than 5lx, the master machine and the linked slave machines are both kept in an off state;
Control mode 1: the mode includes a "welcome to home mode" in which a set time period is 4 hours, and the control mode requires the sensing information of the illuminance sensor 10 and the sensing information of the human body sensor 9. When the rotary switch 11 is at the selected position "1", if the ambient light intensity information is less than 5lx, the MCU control circuit 5 transmits a PWM signal with a duty ratio of 25% to the TRIAC circuit 4, the master and the linked slave units are both turned ON (ON) at 30% and continuously maintained, if the human body sensor 9 detects human body activity information at any time within 4 hours of the duration set by the "welcome-to-home mode", the MCU control circuit 5 gives a low level signal, the master and the linked slave units are turned ON at 100% from the lighting at 30%, and after the lighting at 100% is maintained for 1 minute, if the human body activity information is still detected, the lighting at 100% is continuously maintained for 1 minute, if the human body activity information is not detected after the lighting for 1 minute, the MCU control circuit 5 transmits a PWM signal with a duty ratio of 25% to the TRIAC circuit 4, and the master and the linked slave units are dimmed to 30% and maintained until the lighting at 30% is maintained until the 4 hours set by the "welcome-to-home mode" And the end of the hour.

Control mode 5: the control mode includes a "welcome home mode" in which a time period is set to 8 hours, and the control mode is operated based on the sensing information of the illuminance sensor 10 and the sensing information of the human body sensor 9. When the rotary switch 11 is at the selected position of "5", if the detected ambient light intensity information is less than 25lx, the MCU control circuit 5 sends a PWM signal with a duty ratio of 15% to the TRIAC circuit 4, the master and the linked slave units are both turned ON (ON) at 20% and continuously maintained, if the human body sensor 9 detects human body activity information at any time within 8 hours of the time set by the "welcome-to-home mode", the MCU control circuit 5 gives a low level signal, the master and the linked slave units are turned ON at 100% from the turn-ON state, and after the 100% turn-ON state is maintained for 1 minute, if the human body activity information is still detected, the 100% turn-ON state is continuously maintained for 1 minute, if the human body activity information is not detected after the continuous 1 minute turn-ON, the MCU control circuit 5 sends a PWM signal with a duty ratio of 15% to the TRIAC circuit 4, and the master and the linked slave units are dimmed to 20% and maintained until the turn-ON state is maintained until the ambient light intensity information specified by the "welcome-to The time period is 8 hours.
