DETAILED DESCRIPTION

[0024] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described in detail with reference to the accompanying drawings. In the following description, it should be understood that the directions or positional relationships indicated by "front", "back", "up", "down", "left", "right", "longitudinal", "horizontal", "vertical", "horizontal", "top", "bottom", "inside", "outside", "head", "tail", etc. are based on the directions or positional relationships shown in the accompanying drawings, are constructed and operated in a specific direction, and are only for the convenience of describing the present technical solution, rather than indicating that the device or element referred to must have a specific direction, and therefore cannot be understood as a limitation to the present invention.

[0025] The present invention provides a color temperature and brightness adjustment system for adjusting the brightness and color temperature of a lighting fixture 100 in a target area. The target area may be a conference room, a banquet hall, a restaurant, a carriage, or other occasions where the brightness and color temperature of the lighting fixture 100 need to be adjusted.

[0026] like Figure 1 As shown, the color temperature and brightness adjustment system may include a communication module 400 , a light source driving module 500 , an infrared sensing sensor 200 , a signal acquisition module 300 and a control module 600 .

[0027] Among them, the light source driving module 500 is connected to the lighting fixture 100 in the target area, and the brightness and color temperature of the lighting fixture 100 can be adjusted through the light source driving module 500; the infrared sensing sensor 200 is set in the target area, and is used to output a human body sensing signal when there is human activity in the target area; the signal acquisition module 300 is connected to the infrared sensing sensor 200 and the communication module 400, and is used to collect the human body sensing signal and output it to the communication module 400 for protocol conversion; the control module 600 is connected to the communication module 400 and the light source driving module 500, and a lighting mode is set in the control module 600. The lighting mode includes a working mode and a sleep mode. The control module 600 is used to receive the human body sensing signal after protocol conversion, and determine the lighting mode of the lighting fixture 100 according to the human body sensing signal after protocol conversion, and is also used to output a first adjustment signal to the light source driving module 500 according to the lighting mode to adjust the brightness of the lighting fixture 100.

[0028] Specifically, the control module 600 is pre-set with a lighting mode, which includes a working mode and a sleep mode. In the working mode, the control module 600 outputs a first adjustment signal to the light source driving module 500, so that the lighting fixture 100 is illuminated at high brightness; in the sleep mode, the control module 600 outputs a first adjustment signal to the light source driving module 500, so that the lighting fixture 100 is illuminated at low brightness. There is no specific standard for dividing low brightness and high brightness, and those skilled in the art can divide according to the specific occasions of the target area.

[0029] Specifically, when brightness adjustment is performed, when there are human activities in the target area, the infrared sensing sensor 200 can output a human body sensing signal, that is, the infrared sensing sensor 200 is used to determine whether there are human activities in the target area. When there are human activities in the target area, it means that the lighting fixture 100 needs to be adjusted to high brightness for lighting; when there are no human activities in the target area, the lighting fixture 100 can be adjusted to low brightness for lighting; thereafter, the signal acquisition module 300 acquires the human body sensing signal and outputs it to the communication module 400 for protocol conversion; the communication module 400 outputs the human body sensing signal after protocol conversion to the control module 600, and the control module 600 determines the lighting mode according to the human body sensing signal after protocol conversion, that is, when there are human activities in the target area, the lighting mode is determined to be the working mode, and when there are no human activities in the target area, the lighting mode is determined to be the sleep mode, and further after the lighting mode is determined, a first adjustment signal is output to the light source driving module 500 according to the lighting mode, and the brightness of the lighting fixture 100 is adjusted by the light source driving module 500.

[0030] It can be seen that the color temperature and brightness adjustment system can automatically adjust the brightness without manual adjustment, thus reducing labor costs. At the same time, the brightness can be adjusted in real time according to the activities of people in the target area, saving energy consumption, that is, when there are people in the target area, the lighting is adjusted to high brightness, and when there is no one in the target area, the lighting is adjusted to low brightness.

[0031] In this embodiment, a second duration can be set in the control module 600. When the lighting is adjusted to high brightness, if no human body sensing signal is received during the second duration (it is considered that there is no one in the target area at this time), the control module 600 determines the lighting mode as the sleep mode and outputs a first adjustment signal to the light source driving module 500 to adjust the lighting fixture 100 to low brightness for lighting.

[0032] In some embodiments, a color temperature mode is also provided in the control module 600, and the control module 600 is also used to determine the color temperature mode according to the human body sensing signal after protocol conversion, and is also used to output a second adjustment signal to the light source driving module 500 according to the color temperature mode to adjust the color temperature of the lighting fixture.

[0033] Specifically, when adjusting the color temperature of the lighting fixtures in the target area, the adjustment is also performed based on whether there are people in the target area. When there are people in the target area, the control module 600 can output a second adjustment signal to the light source driving module 500 to enable the lighting fixtures to illuminate at a high color temperature; when there are no people in the target area, the control module 600 can output a second adjustment signal to the light source driving module 500 to enable the lighting fixtures to illuminate at a low color temperature.

[0034] It can be seen that the color temperature and brightness adjustment system can not only automatically adjust the brightness, but also automatically adjust the color temperature, and can create a suitable lighting atmosphere while adjusting the brightness.

[0035] In some embodiments, Figure 1 As shown, a plurality of infrared sensing sensors 200 are provided, and the plurality of infrared sensing sensors 200 are arranged in an array in the target area.

[0036] Specifically, the number of infrared sensing sensors 200 can be set according to the actual size of the target area. For example, when the target area is large, in order to be able to more accurately adjust the brightness and color temperature of the lighting fixture 100, multiple infrared sensing sensors 200 can be set in the target area in an array, for example, 3×3, 3×4, 5×6, 10×10, etc. Those skilled in the art can determine the number of infrared sensing sensors 200 to be set according to the actual situation of the target area, and no excessive restrictions are made here.

[0037] Among them, each infrared sensing sensor 200 can be correspondingly set with a signal acquisition module 300 and a communication module 400. The signal acquisition module 300 is connected to the corresponding infrared sensing sensor 200 and the communication module 400. The signal acquisition module 300 collects the human body sensing signal output by the corresponding infrared sensing sensor 200 and transmits it to the corresponding communication module 400. The communication module 400 converts the received human body sensing signal into a protocol and transmits it to the control module 600.

[0038] In this embodiment, since a plurality of infrared sensing sensors 200 are provided in the target area, the color temperature and brightness can be adjusted more accurately, that is, the human body sensing signal can be accurately output. When there is human activity at any position in the target area, the human body sensing signal can be output in time because a plurality of infrared sensing sensors 200 are provided.

[0039] In some embodiments, the infrared sensing sensor 200 may be a passive infrared pyroelectric sensor (PIRSensor, Passive Infrared Sensor).

[0040] In some embodiments, the working mode may include a plurality of brightness adjustment gears, each brightness adjustment gear corresponding to a brightness value. Figure 1As shown, the color temperature and brightness adjustment system also includes a sound collection module 700, which is connected to the control module 600. The sound collection module 700 is set in the target area, and the sound collection module 700 is used to collect sound signals in the target area; the control module 600 is also used to receive sound signals, and is also used to record the number of human body sensing signals after protocol conversion received in the first time length, and determine the brightness adjustment gear of the working mode according to the number of human body sensing signals after protocol conversion received in the first time length and the sound signal, and then output a third adjustment signal to the light source driving module 500 according to the brightness adjustment gear, wherein the first time length is preset in the control module 600.

[0041] Specifically, the number of people in the target area can be determined by setting a sound collection module 700 in the target area, and combining the sound signal collected by the sound collection module 700 with the number of human body sensing signals after protocol conversion received by the control module 600 for the first time period. When the sound signal collected by the sound collection module 700 is large and the number of human body sensing signals after protocol conversion received in the first time period is large, it can be considered that there are many people in the target area.

[0042] In a specific embodiment, the target area is a conference room, and the brightness adjustment gears may include but are not limited to three gears (a first brightness adjustment gear, a second brightness adjustment gear and a third brightness adjustment gear). The first brightness adjustment gear corresponds to a brightness value, and the corresponding brightness value is relatively high; the third brightness adjustment gear corresponds to a brightness value, and the corresponding brightness value is low; the second brightness adjustment gear corresponds to a brightness value, and the corresponding brightness value is between the brightness value corresponding to the first brightness adjustment gear and the brightness value corresponding to the third brightness adjustment gear.

[0043] When adjusting the brightness, if the sound signal acquired by the sound collection module 700 is large, and the number of human body sensing signals of the first duration recorded by the control module 600 is large (it may be that multiple people are active in the target area, or it may be that a small number of people are active frequently), it is considered that high-brightness lighting is required in the target area. At this time, the third control signal is output to the light source driving module 500 according to the first brightness adjustment gear, so that the lighting fixtures in the target area are illuminated at high brightness; if the sound signal acquired by the sound collection module 700 is large, but the number of human body sensing signals of the first duration recorded by the control module 600 is small, If the sound signal collected by the sound collection module 700 is small and the number of human body sensing signals of the first time length recorded by the control module 600 is small, the third control signal can be output to the light source driving module 500 according to the third brightness adjustment gear, so that the lighting fixtures in the target area are illuminated at medium brightness (medium brightness refers to a brightness value between the brightness value corresponding to the first brightness adjustment gear and the brightness value corresponding to the third brightness adjustment gear); if the sound signal collected by the sound collection module 700 is small and the number of human body sensing signals of the first time length recorded by the control module 600 is small, the third control signal can be output to the light source driving module 500 according to the third brightness adjustment gear, so that the lighting fixtures in the target area are illuminated at low brightness.

[0044] In this embodiment, the brightness of the lighting fixtures in the target area is adjusted in real time by using the sound signal and the number of human body sensing signals recorded in the first time period, so that the brightness adjustment is more accurate and has high precision.

[0045] In some embodiments, the color temperature mode includes several color temperature adjustment gears, each color temperature adjustment gear corresponds to a color temperature value; the control module 600 is also used to determine the color temperature adjustment gear of the color temperature mode according to the number of human body sensing signals and sound signals converted from the protocol received in the first time period, and then output a fourth adjustment signal to the light source driving module 500 according to the color temperature adjustment gear.

[0046] Specifically, the atmosphere of the target area can be determined by the sound collection module 700. When the sound signal collected by the sound collection module 700 is large, it can be preliminarily determined that the atmosphere in the target area is relatively high. In order to avoid the influence of noise outside the target area, when determining the color temperature adjustment gear, the control module 600 further records the number of human body sensing signals after protocol conversion received in the first time period to more accurately judge the atmosphere of the target area, thereby determining the color temperature adjustment gear of the color temperature mode, and then outputting a fourth adjustment signal to the light source driving module 500 according to the color temperature adjustment gear to adjust the color temperature of the lighting fixture.

[0047] In a specific embodiment, the target area is a conference room, and the color temperature adjustment gear may include but is not limited to three gears (a first color temperature adjustment gear, a second color temperature adjustment gear and a third color temperature adjustment gear). The first color temperature adjustment gear corresponds to a color temperature value, and the corresponding color temperature value is relatively high; the third color temperature adjustment gear corresponds to a color temperature value, and the corresponding color temperature value is low; the second color temperature adjustment gear corresponds to a color temperature value, and the corresponding color temperature value is between the color temperature value corresponding to the first color temperature adjustment gear and the color temperature value corresponding to the third color temperature adjustment gear.

[0048] When adjusting the color temperature, if the sound signal acquired by the sound collection module 700 is large, and the number of human body sensing signals of the first time length recorded by the control module 600 is large (it may be that multiple people are active in the target area, or it may be that a small number of people are active frequently), it can be determined that the atmosphere in the target area is relatively high. At this time, the fourth control signal is output to the light source driving module 500 according to the first color temperature adjustment gear, so that the lighting fixtures in the target area are illuminated at a high color temperature; if the sound signal acquired by the sound collection module 700 is large, but the number of human body sensing signals of the first time length recorded by the control module 600 is small, it can be determined that the atmosphere in the target area is a conversation atmosphere. If the sound signal collected by the sound collection module 700 is small and the number of human body sensing signals of the first time length recorded by the control module 600 is small, it can be considered that the atmosphere of the target area is a comfortable atmosphere. At this time, the fourth control signal can be output to the light source driving module 500 according to the third color temperature adjustment gear, so that the lighting fixtures in the target area are illuminated at a medium color temperature (the medium color temperature refers to a color temperature value between the color temperature value corresponding to the first color temperature adjustment gear and the color temperature value corresponding to the third color temperature adjustment gear). If the sound signal collected by the sound collection module 700 is small and the number of human body sensing signals of the first time length recorded by the control module 600 is small, it can be considered that the atmosphere of the target area is a comfortable atmosphere. At this time, the fourth control signal can be output to the light source driving module 500 according to the third color temperature adjustment gear, so that the lighting fixtures in the target area are illuminated at a low color temperature.

[0049] In this embodiment, the color temperature of the lighting fixtures in the target area is adjusted in real time by the sound signal and the number of human body sensing signals recorded in the first time period, so that the color temperature of the lighting fixtures can be adjusted automatically and accurately.

[0050] For example, when adjusting the color temperature, if the sound signal acquired by the sound collection module 700 is large, and the number of human body sensing signals of the first time length recorded by the control module 600 is large (it may be that multiple people are active in the target area, or it may be that a small number of people are active frequently), it is considered that the atmosphere in the target area is high, and the color temperature mode can be determined as the first color temperature adjustment gear, and the control module 600 outputs the fourth adjustment signal according to the first color temperature adjustment gear, so that the lighting fixture 100 is illuminated at a color temperature value of 6500K. If the sound signal collected by the sound collection module 700 is small, and the number of human body sensing signals of the first time length recorded by the control module 600 is small, it is considered that the atmosphere in the target area is a comfortable atmosphere, and the color temperature mode can be determined as the third color temperature adjustment gear, and the control module 600 outputs the fourth adjustment signal according to the third color temperature adjustment gear, so that the lighting fixture 100 is illuminated at a color temperature value of 4500K. If the sound signal collected by the sound collection module 700 is small, but the number of human body sensing signals of the first time length recorded by the control module 600 is large, it is considered that the atmosphere in the target area is a conversation atmosphere. At this time, the color temperature mode can be determined as the second color temperature adjustment gear. The control module 600 outputs a fourth adjustment signal according to the second color temperature adjustment gear, so that the lighting fixture 100 is illuminated at a color temperature value of 5500K.

[0051] It should be noted that the target area is different, and the color temperature adjustment level of the color temperature mode and the color temperature value corresponding to the color temperature adjustment level can be set according to the specific target area. There is no clear standard for whether the sound signal is loud or soft and whether the number of people is large or small. Those skilled in the art can classify according to the specific occasion of the target area, and no excessive restrictions are made here.

[0052] In this embodiment, the atmosphere of the target area is judged by combining the sound signal and the number of human body sensing signals recorded for the first time duration, that is, the atmosphere of the target area is judged based on the sound signal and the number of human body sensing signals recorded for the first time duration, and the color temperature in the target area is further adjusted more accurately, and the adjustment method is more flexible and accurate.

[0053] In this embodiment, the first duration can be understood as a counting cycle. After the counting of a first duration is completed, the count will be reset to facilitate the counting of the next cycle.

[0054] In some embodiments, Figure 2As shown, the sound collection module 700 may include a microphone 701, a signal amplifying unit 702, a first chip U1, a second chip U2, a first resistor R1, a second resistor R2 and a first capacitor C1; wherein the first pin of the microphone 701 is connected to one end of the second resistor R2, the other end of the second resistor R2 is connected to the power supply end VCC, the second pin of the microphone 701 is grounded, and one end of the first capacitor C1 is connected to the third pin of the microphone 701; the other end of the first capacitor C1 is connected to the input end of the signal amplifying unit 702, and the signal amplifying unit 70 The output end of 2 is connected to the 1st pin of the first chip U1; the 2nd pin of the first chip U1 is connected to the 1st pin of the second chip U2, the 3rd pin of the first chip U1 is connected to the 2nd and 3rd pins of the second chip U2, the 4th pin of the first chip U1 is connected to the 4th pin of the second chip U2; the 5th pin of the second chip U2 is grounded, the 6th pin of the second chip U2 is connected to one end of the first resistor R1, the 7th pin of the second chip U2 and the 6th pin of the second chip U2 are also connected to the communication module 400, and the 8th pin of the second chip U2 is connected to the power supply terminal VCC.

[0055] Specifically, the model of the first chip U1 may be, but is not limited to, CMS8S5887. The model of the second chip U2 may be, but is not limited to, IC-ST3485.

[0056] like Figure 2 As shown, the signal amplification unit 702 may include a third resistor R3, a fourth resistor R4, a fifth resistor R5 and a first operational amplifier; wherein, one end of the third resistor R3 is connected to the other end of the first capacitor C1, and the other end of the third resistor R3 is connected to the non-inverting input terminal of the first operational amplifier; one end of the fourth resistor R4 is grounded, and the other end of the fourth resistor R4 is connected to the inverting input terminal of the first operational amplifier, one end of the fifth resistor R5 is connected to the inverting input terminal of the first operational amplifier, and the other end of the fifth resistor R5 is connected to the output terminal of the first operational amplifier; the output terminal of the first operational amplifier is connected to the first pin of the first chip U1.

[0057] When collecting sound signals, the signals collected by the microphone 701 are converted into electrical signals, which are amplified by the first operational amplifier and then transmitted to the first chip U1. The first chip U1 performs digital-to-analog conversion and then outputs the signals to the second chip U2 for protocol conversion and then outputs the signals to the control module 600. That is, the signal output by the second chip U2 after protocol conversion is a sound signal.

[0058] In this embodiment, the microphone 701 ensures the real-time acquisition of the sound signal and has low cost.

The signal acquisition module 300 may be, but is not limited to, a signal acquisition circuit constructed with a chip model of CMS8S5887. The lighting fixture 100 may be an LED (Light Emitting Diode) lamp, and correspondingly, the light source driving module 500 is any LED driving power supply capable of realizing the above functions, wherein, when adjusting the color temperature and brightness of the LED lamp, different pulse width modulation (PWM) signals are output to the LED driving power supply through the dimmer, and then the color temperature and brightness of the LED lamp are adjusted through the LED driving power supply, that is, the first adjustment signal, the second adjustment signal, the third adjustment signal and the fourth adjustment signal are all pulse width modulation signals. The communication module 400 may be an RS485 communication module, for example, the communication module 400 may be a communication circuit constructed with a MAX3485AE chip.

[0060] In some embodiments, Figure 3 As shown, the present invention also provides an adjustment method for the color temperature and brightness adjustment system as described above, and the adjustment method comprises the following steps: S100, the control module obtains the human body sensing signal after protocol conversion; S200, the control module determines the lighting mode of the lighting fixture according to the human body sensing signal after protocol conversion, wherein the lighting mode includes a working mode and a sleeping mode; S300: The control module outputs a first adjustment signal to the light source driving module according to the lighting mode to adjust the brightness of the lighting fixture.

[0061] Specifically, a lighting mode is pre-set in the control module. When there is human activity in the target area, the infrared sensing sensor outputs a human body sensing signal to the signal acquisition module. After receiving the human body sensing signal, the signal acquisition module transmits it to the communication module for protocol conversion. The human body sensing signal after protocol conversion is transmitted to the control module. The control module determines the lighting mode according to the human body sensing signal.

[0062] It can be seen that this adjustment method can automatically adjust the brightness without manual adjustment, thus reducing labor costs. At the same time, it can adjust the brightness in real time according to the activities of people in the target area, saving energy consumption (when there are people activities in the target area, the brightness of the lighting fixture is adjusted to high brightness for lighting, and when there are no people activities in the target area, the brightness of the lighting fixture is adjusted to low brightness for lighting).

[0063] In some embodiments, Figure 4 As shown, the adjustment method also includes: S400, the control module determines the color temperature mode according to the human body sensing signal after protocol conversion; S500: The control module outputs a second adjustment signal to the light source driving module according to the color temperature mode to adjust the color temperature of the lighting fixture. The details are as described in the specific embodiment of the color temperature and brightness adjustment system, and will not be described in detail here.

[0064] Furthermore, the working mode includes a plurality of brightness adjustment gears, each of which corresponds to a brightness value. Figure 5 As shown, after the step in which the control module outputs the first adjustment signal to the light source driving module according to the lighting mode to adjust the brightness of the lighting fixture, the following steps are also included: S600, the control module records the number of human body sensing signals after protocol conversion received within a first time period, wherein the first time period is a preset time period; S700, the control module receives a sound signal; S800, the control module determines a brightness adjustment level according to the number of human body sensing signals and sound signals received after protocol conversion for the first duration, and then outputs a third adjustment signal according to the brightness adjustment level; S900: The control module determines the color temperature adjustment level according to the number of human body sensing signals and sound signals received after protocol conversion in the first time period, and then outputs a fourth adjustment signal according to the color temperature adjustment level. The specific details are as described in the specific embodiment of the color temperature and brightness adjustment system, and will not be described in detail here.

[0065] In some embodiments, the present invention further provides a lighting device, which may include a lighting fixture 100 and the color temperature and brightness adjustment system as described above, wherein the lighting fixture 100 is connected to a light source driving module 500 in the color temperature and brightness adjustment system.

The control module 600 is used to receive the human body sensing signal after protocol conversion, and determine the lighting mode of the lighting fixture 100 according to the human body sensing signal after protocol conversion, and is also used to output a first adjustment signal to the light source driving module 500 according to the lighting mode to adjust the brightness of the lighting fixture 100. The specific embodiments are described in detail in the above-mentioned specific embodiments of the color temperature and brightness adjustment system, and will not be described in detail here.

For technical details not disclosed in the adjustment method and lighting device embodiments, please refer to the description of the color temperature and brightness adjustment system embodiments of the present invention for understanding.

[0068] In summary, the present invention provides a color temperature and brightness adjustment system, adjustment method and lighting equipment, which have the following beneficial effects: According to the human body sensing signal collected by the infrared sensing sensor 200 in the target area, the control module 600 determines whether there is human activity in the target area according to the human body sensing signal after protocol conversion, and then determines the lighting mode. After the mode is determined, it outputs a first adjustment signal to the light source driving module 500 to adjust the brightness of the lighting fixture 100, avoiding the need to manually adjust the brightness when there is someone in the target area.
