Description

Technical Field

[0001] This invention relates to the field of intelligent lighting technology, and more particularly to an intelligent dimming lighting lamp. Background Technology

[0002] After receiving the tobacco leaves, the raw tobacco needs to be graded in order to proceed with the re-drying process according to different grades. Tobacco leaf grading is mainly achieved through "sight, touch, and smell," with sight being the core element. There are many types of tobacco leaves, and tobacco leaves from different origins, varieties, and grades differ in appearance characteristics such as color and luster. Appropriate light sources can enhance the identification of target characteristics, so the lighting conditions at the sorting site are one of the important factors in the on-site working environment.

[0003] Currently, re-drying plants often use traditional lighting fixtures with fixed illuminance and color temperature. These fixtures are often single color temperature, which cannot effectively simulate natural light. Furthermore, the light cannot be adjusted according to environmental changes, making them poorly adaptable to the environment. They may even have problems such as insufficient illuminance, low color rendering index, and color temperature deviation. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent dimming lighting lamp. It uses a photosensitive sensor to detect the ambient light intensity during leaf selection in real time, and a color temperature sensor to detect the ambient light color temperature during leaf selection. When the light intensity is outside a first set range, the control module adjusts the lighting intensity to the first set range via the lighting drive module. When the light color temperature is outside the color temperature threshold corresponding to the light intensity, the control module adjusts the light color temperature according to the light intensity. This solves the problems of existing lighting fixtures, such as poor simulation of natural light sources, color temperature deviation during leaf selection, and insufficient illuminance.

[0024] The technical solutions of the embodiments of this application are briefly described below: According to some embodiments, such as Figure 1 As shown, this application provides an intelligent dimming lighting fixture, which includes: A photosensitive sensor is used to detect the intensity of light in the environment. Color temperature sensor, used to detect the color temperature of ambient light; The system includes a control module, a lighting driver module, and a lighting lamp. The control module is connected to a photosensitive sensor, a color temperature sensor, and the lighting driver module, respectively. The lighting driver module controls the lighting lamp.

[0025] The working principle of the above embodiment is as follows: the control module obtains the light intensity of the leaf selection environment in real time through a photosensitive sensor. When the light intensity is lower than the preset first set range, the control module increases the duty cycle of the drive signal and outputs the drive signal to the lighting drive module, which then increases the light intensity of the lighting lamp to the first set range. When the light intensity is higher than the preset first set range, the control module decreases the duty cycle of the drive signal and outputs the drive signal to the lighting drive module, which then reduces the light intensity of the lighting lamp to the first set range.

[0026] The control module obtains the ambient light color temperature through a color temperature sensor. When the light color temperature is not within the color temperature threshold corresponding to the light intensity, the control module adjusts the light color temperature according to the light intensity.

[0027] The following is in conjunction with the appendix to this instruction manual. Figures 1 to 3 The preferred embodiments of this disclosure will be further described in detail below.

The other end of the first resistor R1 is connected to the photosensitive sensor. The other end of the second resistor R2 is connected to ground through the third resistor R3. The other end of the first capacitor C1 is grounded. The non-inverting input of the first comparator U1 is connected to the gear adjustment module.

The collector of the first NPN transistor QN1 is connected to the control module, one end of the fifth resistor R5, and one end of the second capacitor C2. The other end of the fifth resistor R5 is connected to the second power supply V2. The emitter of the first NPN transistor QN1 and the other end of the second capacitor C2 are grounded.

[0029] Furthermore, such as Figure 1 As shown, the intelligent dimming lighting also includes a second comparator module, which includes a second comparator U2, a second NPN transistor QN2, a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, a ninth resistor R9, a tenth resistor R10, a third capacitor C3, and a fourth capacitor C4. Their specific connection method is as follows: The non-inverting input of the second comparator U2 is connected to one end of the seventh resistor R7, one end of the eighth resistor R8, and one end of the third capacitor C3. The other end of the eighth resistor R8 and the other end of the third capacitor C3 are grounded. The other end of the seventh resistor R7 is connected to one end of the sixth resistor R6. The other end of the sixth resistor R6 is connected to the photosensitive sensor. The inverting input of the second comparator U2 is connected to the gear adjustment module. The output of the second comparator U2 is connected to the base of the second NPN transistor QN2 through the ninth resistor R9. The collector of the second NPN transistor QN2 is connected to the control module, one end of the tenth resistor R10, and one end of the fourth capacitor C4. The other end of the tenth resistor R10 is connected to the second power supply V2. The emitter of the second NPN transistor QN2 and the other end of the fourth capacitor C4 are grounded.

[0030] Furthermore, such as Figure 1 As shown, the gear adjustment module includes a gear adjustment knob S1, an eleventh resistor R11, a twelfth resistor R12, a thirteenth resistor R13, a fourteenth resistor R14, a fifteenth resistor R15, and a fifth capacitor C5. Their specific connection method is as follows: The first pin of the gear adjustment knob S1 on the first side is connected to the second power supply V2 through the eleventh resistor R11. The second and third pins of the gear adjustment knob S1 on the first side are connected to the second power supply V2. The first and second pins of the gear adjustment knob S1 on the second side are connected to one end of the twelfth resistor R12. The third pin of the gear adjustment knob S1 on the second side is connected to one end of the thirteenth resistor R13 and one end of the fourteenth resistor R14. The other ends of the twelfth resistor R12, the thirteenth resistor R13, and the fourteenth resistor R14 are connected together and connected to the non-inverting input of the first comparator U1, the inverting input of the second comparator U2, one end of the fifteenth resistor R15, and one end of the fifth capacitor C5. The other ends of the fifteenth resistor R15 and the fifth capacitor C5 are grounded.

[0031] The working principle of the above embodiment is as follows: when the gear adjustment knob S1 is adjusted to the first gear, the first pin on the first side and the first pin on the second side of the gear adjustment knob S1 are connected. There are eleventh resistor R11 and twelfth resistor R12 in the circuit. At this time, the resistance is the largest. The voltage input to the non-inverting input terminal of the first comparator U1 and the inverting input terminal of the second comparator U2 is low. At this time, the light intensity of the leaf selection environment is maintained within the first set range.

[0032] When the light intensity is within the first set range, the voltage at the inverting input of the first comparator U1 is greater than the voltage at the non-inverting input, and the voltage at the inverting input of the second comparator U2 is also greater than the voltage at the non-inverting input. Both the outputs of the first comparator U1 and the second comparator U2 output low-level signals, and the first NPN transistor QN1 and the second NPN transistor QN2 are turned off. The control module receives a high-level signal through the collector of the first NPN transistor QN1 and a high-level signal through the collector of the second NPN transistor QN2. At this time, the control module determines that the light intensity is within the first set range.

[0033] When the light intensity is lower than the preset first set range, it is detected by the first comparator U1. The voltage at the inverting input terminal of the first comparator U1 is less than the voltage at the non-inverting input terminal, and the first comparator U1 outputs a high-level signal. The first NPN transistor QN1 is turned on, and the control module receives a low-level signal through the collector of the first NPN transistor QN1. At this time, the control module determines that the light intensity is lower than the first set range. The control module increases the duty cycle of the drive signal and outputs the drive signal to the lighting drive module. The lighting drive module increases the light intensity of the lamp to the first set range.

[0034] When the light intensity exceeds the preset first set range, it is detected by the second comparator U2. The voltage at the inverting input terminal of the second comparator U2 is less than the voltage at the non-inverting input terminal, and the second comparator U2 outputs a high-level signal. The second NPN transistor QN2 is turned on, and the control module receives a low-level signal through the collector of the second NPN transistor QN2. At this time, the control module determines that the light intensity exceeds the first set range. The control module reduces the duty cycle of the drive signal and outputs the drive signal to the lighting drive module. The lighting drive module reduces the light intensity of the lamp to the first set range.

[0035] Furthermore, when the gear adjustment knob S1 is adjusted to the second gear, the second pin on the first side and the second pin on the second side of the gear adjustment knob S1 are connected. A twelfth resistor R12 is present in the circuit, and its resistance is moderate. The voltage input to the non-inverting input of the first comparator U1 and the inverting input of the second comparator U2 is moderate, and the light intensity of the leaf selection environment is maintained within the second set range. When the gear adjustment knob S1 is adjusted to the third gear, the third pin on the first side and the third pin on the second side of the gear adjustment knob S1 are connected. A thirteenth resistor R13 and a fourteenth resistor R14 are connected in parallel in the circuit, and their resistance is minimum. The voltage input to the non-inverting input of the first comparator U1 and the inverting input of the second comparator U2 is high, and the light intensity of the leaf selection environment is maintained within the third set range.

[0036] Among them, the light intensity of the third set range is greater than the light intensity of the second set range, which is greater than the light intensity of the first set range.

[0037] According to some embodiments, such as Figure 1 As shown, the intelligent dimming lighting also includes a first diode D1, a second diode D2, a third diode D3, and a sixteenth resistor R16, with the specific connection method as follows: The positive terminals of the first diode D1, the second diode D2, and the third diode D3 are all connected to the photosensitive sensor. The negative terminal of the first diode D1 is connected to the other end of the first resistor R1. The negative terminal of the second diode D2 is connected to the control module through the sixteenth resistor R16. The negative terminal of the third diode D3 is connected to the other end of the sixth resistor R6.

[0038] This application provides a first diode D1, a second diode D2, and a third diode D3 to prevent mutual interference between the first comparator U1, the second comparator U2, and the control module when detecting light intensity.

[0039] Specifically, the control module detects the light intensity through the second diode D2 and adjusts the light color temperature according to the real-time light intensity. Different light intensities correspond to different light color temperatures, as shown in Table 1 below: Table 1

[0040] According to some embodiments, such as Figure 2 As shown, the lighting driver module includes a third NPN transistor QN3 and an eighteenth resistor R18. The lighting lamps include multiple red lamps RD, multiple green lamps GD, and multiple blue lamps BD. Their specific connection method is as follows. The collector of the third NPN transistor QN3 is connected to the first power supply V1 through the eighteenth resistor R18. The base of the third NPN transistor QN3 is connected to the control module. The emitter of the third NPN transistor QN3 is connected to the positive terminals of multiple red lights RD, multiple green lights GD, and multiple blue lights BD. The negative terminals of multiple red lights RD, multiple green lights GD, and multiple blue lights BD are connected to the control module.

[0041] In the above embodiment, the control module controls the light intensity of the lighting lamp through the third NPN transistor QN3, and the control module directly controls the light color temperature of the lighting lamp.

[0042] Furthermore, such as Figure 2 As shown, the lighting driver module also includes a red light regulating transistor RQN, a green light regulating transistor GQN, a blue light regulating transistor BQN, and a nineteenth resistor R19. Their specific connection methods are as follows: The control module is connected to the base of the red light regulating transistor RQN, the base of the green light regulating transistor GQN, and the base of the blue light regulating transistor BQN. The collector of the red light regulating transistor RQN is connected to the negative terminals of multiple red lights RD, the collector of the green light regulating transistor GQN is connected to the negative terminals of multiple green lights BD, and the collector of the blue light regulating transistor BQN is connected to the negative terminals of multiple blue lights BD. The emitters of the red light regulating transistor RQN, the green light regulating transistor GQN, and the blue light regulating transistor BQN are all grounded through the nineteenth resistor R19.

[0043] In the above embodiment, the nineteenth resistor R19 is formed by two resistors connected in parallel. The control module controls the light intensity of the lighting lamp through the third NPN transistor QN3, and controls the light color temperature of the lighting lamp through the red light regulating transistor RQN, the green light regulating transistor GQN, and the blue light regulating transistor BQN.

[0044] When the gear adjustment knob S1 is adjusted to the first gear, if the light intensity is lower than the first set range, the control module increases the duty cycle of the drive signal and outputs the drive signal to the base of the third NPN transistor QN3. The third NPN transistor QN3 increases the light intensity of the lamp to the first set range. If the light intensity is higher than the first set range, the control module decreases the duty cycle of the drive signal and outputs the drive signal to the base of the third NPN transistor QN3. The third NPN transistor QN3 decreases the light intensity of the lamp to the first set range.

[0045] The control module obtains the ambient light color temperature through a color temperature sensor. When the light color temperature is not within the color temperature threshold corresponding to the light intensity, the control module adjusts the brightness ratio of the red light RD, green light GD, and blue light BD through the red light regulating transistor RQN, green light regulating transistor GQN, and blue light regulating transistor BQN, so as to adjust the light color temperature to within the light intensity threshold corresponding to the first set range.

[0046] According to some embodiments, such as Figure 3 As shown, the intelligent dimming lighting also includes a power supply module, which includes a fuse F, a rectifier bridge DB, a second PNP transistor QP2, a third PNP transistor QP3, a twentieth resistor R20, a twenty-first resistor R21, a twenty-second resistor R22, a twenty-third resistor R23, a twenty-fourth resistor R24, a twenty-fifth resistor R25, and an eighth capacitor C8. The specific connection method is as follows: The first input terminal of the rectifier bridge DB is connected to the first electrode of the main power supply through fuse F. The second input terminal of the rectifier bridge DB is connected to the second electrode of the main power supply. The positive output terminal of the rectifier bridge DB is connected to one end of the sixth capacitor C6, one end of the seventh capacitor C7, and one end of the twentyth resistor R21 through the twentieth resistor R20. The negative output terminal of the rectifier bridge DB serves as ground. The other ends of the sixth capacitor C6 and the seventh capacitor C7 are grounded. The other end of the twenty-first resistor R21 is connected to the emitter of the second PNP transistor QP2. The base of the second PNP transistor QP2 is connected to the third PNP transistor. The emitter of transistor QP3 and the collector of the second PNP transistor QP2 output the first power supply V1. One end of the eighth capacitor C8 is connected to the first power supply V1, and the other end of the eighth capacitor C8 is grounded. The base of the third PNP transistor QP2 is connected to one end of the twenty-second resistor R22, one end of the twenty-fourth resistor R24, and one end of the twenty-fifth resistor R25. The other end of the twenty-second resistor R22 and the other end of the twenty-fifth resistor R25 are grounded. The other end of the twenty-fourth resistor R24 ​​is connected to the first power supply V1. The collector of the third PNP transistor QP3 is grounded through the twenty-third resistor R23.

[0047] Furthermore, such as Figure 3 As shown, the power module also includes a three-terminal Zener diode U3, a Zener diode DZ, a 26th resistor R26, a 27th resistor R27, and a 9th capacitor C9. Their specific connection methods are as follows: The input terminal of the three-terminal Zener diode U3 is connected to the first power supply V1. The output terminal of the three-terminal Zener diode U3 outputs the second power supply V2 through the twenty-sixth resistor R26. One end of the twenty-seventh resistor R27, one end of the ninth capacitor C9, and the cathode of the Zener diode DZ are connected to the second power supply V2. The other end of the twenty-seventh resistor R27, the other end of the ninth capacitor C9, and the anode of the Zener diode DZ are grounded.

[0048] The working principle of the above embodiment is as follows: when the voltage of the first power supply V1 exceeds the set voltage, the third PNP transistor QP3 decreases its opening, causing the second PNP transistor QP2 to decrease its opening, thereby further reducing the voltage of the first power supply V1; when the voltage of the first power supply V1 is lower than the set voltage, the third PNP transistor QP3 increases its opening, causing the second PNP transistor QP2 to increase its opening, thereby further increasing the voltage of the first power supply V1. The second PNP transistor QP2 and the third PNP transistor QP3 form a closed-loop control, improving the stability of the voltage of the first power supply V1.

[0049] In this system, the voltage of the first power supply V1 is greater than the voltage of the second power supply V2. The three-terminal Zener diode U3 and the Zener diode DZ are used to step down the voltage of the first power supply V1 to the second power supply V2. At the same time, the three-terminal Zener diode U3 and the Zener diode DZ also play a role in voltage regulation.

[0050] According to some embodiments, such as Figure 2 As shown, the intelligent dimming lighting also includes a start-up module, which comprises a manual switch S2, a 28th resistor R28, a 29th resistor R29, a 30th resistor R30, and a 10th capacitor C10. The specific connection method is as follows: One end of the manual switch S2 is connected to the second power supply V2 through the twenty-eighth resistor R28. The other end of the manual switch S2 is connected to the control module, one end of the thirtieth resistor R30 and one end of the tenth capacitor C10 through the twenty-ninth resistor R29. The other end of the thirtieth resistor R30 and the other end of the tenth capacitor C10 are grounded.

[0051] In the above embodiment, when it is necessary to turn on the lighting, the manual switch S2 is pressed. When the manual switch S2 is closed, the control module receives a high-level signal through the manual switch S2, determines that the lighting needs to be turned on, and then the control module drives the lighting to light up through the lighting driver module.

[0052] When it is necessary to turn off the lights, press the manual switch S2 again. The manual switch S2 will open, and the control module will receive a low-level signal through the 30th resistor R30. It will then determine that the lights need to be turned off and turn off the lights through the lighting driver module.
