Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Figure 1 This is a structural diagram of an intelligent bedroom light control system proposed in this utility model;

[0019] Figure 2 This is a circuit diagram of the intelligent control module in an intelligent bedroom light control system according to this utility model. Detailed Implementation

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figure 1 A smart bedroom light control system includes a door infrared detection module, a human motion detection module, and a smart control module; the door infrared detection module and the human motion detection module are respectively connected to the smart control module;

[0022] The intelligent control module includes a sleep light control circuit, an entry / exit judgment circuit, and an intelligent light control circuit; the portal infrared detection module includes an inner portal infrared detection module and an outer portal infrared detection module, and the portal infrared detection module is connected to the entry / exit judgment circuit; the human motion detection module is connected to the sleep light control circuit.

[0023] For the diverse lighting needs of the bedroom environment, intelligent management of indoor light, human activity, and mode switching is required. This includes automatic light switching when people enter or exit, adjusting light brightness based on indoor lighting conditions, and defining lighting for nighttime sleep. An infrared doorway detection module, a human motion detection module, and a light detection branch collect information about external conditions and output control signals to the intelligent control module. The control circuit then drives the lights and includes a sleep mode switching button to address the specific needs of nighttime sleep.

[0024] like Figure 2 The entry / exit judgment circuit receives signals from the infrared detection modules inside and outside the portal. By detecting the timing of the signals from the inside and outside detection modules, it determines the entry / exit status of personnel and drives the lighting control branch in non-sleep mode.

[0025] The entry / exit detection circuit includes thyristors U6, U11, U12, PMOS transistors Q1 and Q4, and transistors Q11 and Q5. The source of Q4 is connected to the infrared detection module outside the portal, the gate is connected to the negative terminal of U12, and the drain is connected to the control terminal of U11. The source of Q1 is connected to the infrared detection module inside the portal, the gate is connected to the negative terminal of U11, and the drain is connected to the control terminal of U12. The positive terminals of U11 and U12 are connected to the collector of Q11. The collector of Q11 is connected to the power supply, the emitter is grounded, and the base is connected to the negative terminal of U6 and the reflector of Q5, respectively. The negative terminal of U11 is connected to the control terminal of U6. The negative terminal of U12 is connected to the base of Q5. The collector of Q5 is connected to the positive terminal of U6 and the power supply, respectively. The emitter of Q5 is grounded.

[0026] The infrared detection module inside the portal and the infrared detection module outside the portal are installed on the inside and outside of the portal, respectively, and emit a high-level signal when a person passes by; the personnel movement detection module emits a high-level signal when a person's movement is detected.

[0027] When the infrared detection module on the outside of the portal detects a human body first, it turns on thyristor U11, causing Q1 to turn off. The output voltage of U11 then turns on thyristor U6, which in turn turns on transistors Q2 and Q3, which transmit signals between the light detection branch and the lighting control branch. This achieves the effect of turning on the lights when someone enters, and simultaneously turns on transistor Q11, resetting thyristor U11. Similarly, when the infrared detection module on the inside of the portal detects a human body first, it turns off Q4 and turns on transistor Q5, causing Q2 and Q3 to turn off, turning off the lights when someone leaves. The emitter of Q5 is connected to Q11, resetting the thyristor.

[0028] The intelligent lighting control circuit includes a light detection branch and a lighting control branch;

[0029] The light detection branch includes a photoresistor R2, comparators U7 and U9; R2 and resistor R3 form a voltage divider circuit, inputting the voltage across R2 to the positive comparison terminals of U7 and U9 respectively; the inverting comparison terminal of U7 is connected to the first threshold voltage, the negative input terminal is grounded, and the positive input terminal is connected to the power supply; the inverting comparison terminal of U9 is connected to the second threshold voltage, the negative input terminal is grounded, and the positive input terminal is connected to the power supply; the output terminal of U7 is connected to pin 1 of optocoupler U8; the output terminal of U9 is connected to pin 1 of U10.

[0030] The lighting control branch includes transistors Q2, Q3, Q6, Q7, low-brightness lamp U1, and lamp U5; the bases of Q2 and Q3 are connected to the negative terminal of U6; the collector of Q2 is connected to pin 2 of U8, and the emitter is connected to the base of Q6; the collector of Q6 is connected to the power supply, and the emitter is connected to U1 through an RC circuit; the collector of Q3 is connected to pin 2 of U10, and the emitter is connected to the base of Q7; the collector of Q7 is connected to both the power supply and pin 1 of switch K2, and the emitter is connected to U5 through an RC circuit; pin 2 of K2 is connected to U5 through an RC circuit; pins 4 of U8 and U10 are connected to the power supply.

[0031] First, a voltage divider network is formed using photoresistors to obtain external light information. The dimmer the light, the greater the resistance of R2, and the greater the voltage division. Two comparators are used to distinguish between evening and nighttime light conditions using preset thresholds. U7 corresponds to the evening situation, and the corresponding lighting control branch uses low-brightness lamps, and the lamps are turned on and off slowly through an RC circuit. Similarly, U9 corresponds to lamps with normal brightness and is equipped with an emergency button K2 for handling lighting situations in emergency situations.

[0032] The sleep light control circuit includes a control switch K1, transistors Q8, Q9, Q10, and a low-brightness lamp U2. The collector of Q8 is connected to pin 3 of U8 and pin 3 of U10. The base of Q8 is connected to pin 2 of K1 and the collector of Q5. Pin 1 of K1 is connected to the power supply. The emitter of Q8 is connected to the base of Q9. The collector of Q9 is connected to the power supply, and the emitter is connected to the collector of Q10. The base of Q10 is connected to the human motion detection module, and the emitter is connected to U2 through an RC circuit.

[0033] The sleep light circuit switches modes via control button K1. When K1 is closed, sleep mode is activated, Q5 conducts, the entry / exit judgment circuit stops working, and the light detection branch no longer controls the light control branch. The light control branch does not work when the emergency button K2 is open. When K1 is closed, the light detection branch detects insufficient external light, the emitter of Q8 shows a high level, and Q9 conducts. At this time, when the human motion detection module detects human movement, Q10 conducts, and the low-brightness lamp U2 gradually brightens, meeting the lighting needs during nighttime sleep.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
