Description

Technical Field

[0002] The lighting manager is used to control the brightness of the lighting system so as to achieve different levels of lighting. The currently adopted lighting manager is mainly a time control switch, which is used to control the time of turning on and off the lighting system.

[0032] In order to solve the problem that when simulating the sunrise and sunset scenarios through a time control switch currently, a large amount of manual intervention is required, which is rather cumbersome. The present utility model proposes a lighting manager system, enabling the system to automatically output a 0 - 10V signal at a fixed time and in a fixed quantity, thereby automatically simulating the sunrise and sunset effects, as Figure 1 - Figure 10 shown. The system includes:

[0033] A current input circuit 11 for converting an external input power supply into a stable first current, further including a first conversion module 12 for converting the first current into a second current for use by the signal processing module 2, and a second conversion module 13 for converting the first current into a third current for use by the signal output module 3. The current input circuit 11, the first conversion module 12, and the second conversion module 13 together constitute the power supply module 1. First, obtain a current with a stable voltage through the current input circuit 11, and then convert the voltage of the current through the first conversion module 12 and the second conversion module 13, thereby supplying power to the corresponding signal processing module 2 and signal output module 3;

[0034] A signal processing module 2 for obtaining the current time and the sunrise period, sunshine period, and sunset period set by the user, and adjusting the output PWM signal to the corresponding design value according to the period in which the current time is located, and then outputting it to the signal output module 3.

[0035] A signal output module 3 for amplifying and outputting the PWM signal output by the signal processing module 2. The signal processing module 2 outputs electrical signals with different voltages between 0 - 10V, thereby being able to control the brightness of the lighting system, and thus being able to automatically adjust the brightness of the lighting system through a logic circuit at a predetermined time according to the set parameters.

[0036] The current input circuit 11 needs to convert the input current into a stable 12V current. The following introduces the circuit structure of the current input circuit 11.

The 12V external power supply provides +12V voltage for the system through the fuse F1, the MOS transistor Q1, the MOS transistor Q2, and the coil FB1.

[0037] Since the operating voltages of the signal processing module 2 and the signal output module 3 are different, it is necessary to convert the +12V voltage into their operating voltages. The first conversion module 12 needs to convert the voltage into +3.3V. The first conversion module 12 includes a voltage regulator VR1 connected to the output port of the current input circuit 11. A capacitor C4 grounded is connected to the 3rd pin of the voltage regulator VR1. A capacitor C5 grounded and a diode D5 are connected to the 1st pin of the voltage regulator VR1. The +12V obtains a +3.3V voltage through the voltage regulator VR1.

[0038] The second conversion module 13 needs to convert the +12V voltage into a +5V voltage. Therefore, the second conversion module 13 includes a voltage regulator VR2 connected to the output port of the current input circuit 11. A capacitor C6 grounded is connected to the 3rd pin of the voltage regulator VR2. A capacitor C7 grounded is connected to the 2nd pin of the voltage regulator VR2. The +12V voltage obtains a +5V voltage through the voltage regulator VR2.

[0039] The signal output module 3 cooperates with the instructions of the signal processing module 2 to achieve the purpose of outputting a 0 - 10V voltage regularly and quantitatively, and amplifies the output signal. The signal output module 3 includes a resistor R8 connected to the output end of the signal processing module 2, a capacitor C12 grounded, a resistor R11, and a capacitor C13 grounded;

[0040] It also includes an LED driver chip U1. The 3rd pin of the LED driver chip U1 is connected between a resistor R11 and a capacitor C13. A capacitor C8 is connected between the 4th pin and the 1st pin of the LED driver chip U1. A resistor R7, transistors Q4, Q5 and Q6 are also connected to the 1st pin of the LED driver chip U1.

After the resistor F4 is connected to the emitters of transistor Q4 and transistor Q5 and they are connected in parallel with capacitors C14, C15, resistor R12, diode D6 and capacitor C16 which are all grounded. A resistor F2 is connected to the collector of transistor Q4. A grounded capacitor C10 is connected to the 5th pin of the LED driver chip U1. A resistor R6 and a resistor R5 connected to the resistor F4 are connected in parallel to the 4th pin of the LED driver chip U1;

[0041] The signal processing module 2 is a kind of single-chip microcomputer and needs to communicate with the signal output module 3. The signal processing module 2 includes a single-chip microcomputer U2. A resistor R16, a MOS transistor Q7 and a resistor R17 are sequentially arranged on the 17th pin of the single-chip microcomputer U2. A resistor R18, a MOS transistor Q8 and a resistor R19 are sequentially arranged on the 18th pin of the single-chip microcomputer U2. The model of the single-chip microcomputer U2 can be the single-chip microcomputer of STM32F031F6P6-TSSOP-20. Of course, a clock circuit, an indicator light circuit, etc. may also be required in the circuit and will not be elaborated here.

[0042] The working principle of this system is generally described below. +5V provides the working voltage for the LED driver chip U1. The LED driver chip U1 communicates with the 17th pin and the 18th pin of the single-chip microcomputer U2 through the MOS transistors Q7 and Q8;

[0043] The single-chip microcomputer U2 executes actions according to the received instructions:

[0044] A: When the time is in the sunrise period, the 13th pin of the single-chip microcomputer U2 outputs a PWM signal. This signal will slowly rise to the designed value according to the set sunrise duration. This signal is provided to the 3rd pin of the LED driver chip U1 through the resistors R8 and R11. The LED driver chip U1 outputs a signal through the 1st pin and provides it to the base of the transistor Q4 through the resistor R7. The +12V voltage passes through the coil F2, the collector of the transistor Q4, and a 0 - 10V voltage is output from the emitter and then output through the fuse F5;

[0045] B: When the time is in the sunshine period, the 13th pin of the single-chip microcomputer U2 keeps outputting the set maximum brightness. At this time, the emitter of the triode Q4 outputs a stable 0 - 10V dimming signal. This signal is provided to the 3rd pin of the LED driver chip U1 after passing through the resistors R8 and R11. The signal output from the 1st pin of the LED driver chip U1 is provided to the base of the triode Q4 through the resistor R7.

[0046] C: When the time is in the sunset period, the PWM signal output from the 13th pin of the single-chip microcomputer U2 will gradually decrease to the designed value according to the set sunset duration. This signal is provided to the 3rd pin of the LED driver chip U1 after passing through the resistors R8 and R11. The signal output from the 1st pin of the LED driver chip U1 is provided to the base of the triode Q4 through R7. The +12V voltage passes through the resistor F2 and the collector of the triode Q4, and the 0 - 10V voltage output from the emitter is then output through the F5 fuse;

[0047] D: The external 0 - 10V signal passes through the positive pole of the P3 port and is provided to the 6th pin of the single-chip microcomputer U2 through the resistor R14. The single-chip microcomputer U2 compares the voltage sampled at the 6th pin with the set value. If the 0 - 10V voltage is higher than the output voltage set in the design, the single-chip microcomputer U2 outputs the voltage sampled from the external signal. The signal transmission is still: This signal is provided to the 3rd pin of the LED driver chip U1 after passing through the resistors R8 and R11. The signal output from the 1st pin of the LED driver chip U1 is provided to the base of the triode Q4 through the resistor R7.
