Correspondingly, FIG. 2 is a schematic diagram showing the basic structure of an intelligent control device of a lighting system according to an embodiment of the present invention. As shown in FIG. 2, the intelligent control device of the illumination system comprises a switch control component 100, a constant voltage constant current power conversion control component 200, an MCU control component 300, an LED light source load control component 400, and an infrared receiving control component. 500. The switch control component 100 is an optional component used in the intelligent control device of the illumination system for controlling the on and off of the input voltage. When the switch control component 100 is turned on, the input voltage can pass through the switch control component 100. The other parts of the intelligent control device of the lighting system are powered up, and when the switch control component 100 is disconnected, the input voltage is blocked outside the intelligent control device of the lighting system, and the intelligent control device of the lighting system is powered down.

When the switch control component 100 is turned on to enable the input voltage to be powered on, the constant voltage constant current power conversion control component 200 coupled to the switch control component 100 is activated and can pass AC-DC power. The conversion circuit provides adaptive power to the LED load. Further, the illumination system of the embodiment of the present invention includes a plurality of LED loads that can be combined, and the specified combination of the plurality of LED loads can be described as LED status information.

After the constant voltage constant current power conversion control component 200 is started, the MCU control component 300 coupled thereto can be synchronously started. Subsequently, the MCU control component 300 can use its own memory function to memory store the status information of the LEDs. When the lighting system is next started, the LED status information stored by the MCU control component itself can be read. Further, after the LED status information is acquired, it can be parsed. Specifically, the LED status information can be parsed into control information for different LED loads involved in the specified combination. Furthermore, the MCU control component 300 can transmit the generated control information to the LED light source load control component 400 coupled thereto, and the LED light source load control component 400 can sequentially activate different LED loads based on the analyzed control information. At the same time, the LED light source load control component 400 is also coupled with the constant voltage constant current power conversion control component 200. At this time, the constant voltage constant current power conversion control component 200 can convert the input voltage of the illumination system through the AC-DC power conversion circuit. In turn, the specific LED load in the LED light source load control component 400 is provided with corresponding adaptation power to meet user requirements.

Further, FIG. 3 is a detailed structural diagram of an intelligent control device of a lighting system according to an embodiment of the present invention. As shown in FIG. 3, the constant voltage constant current power conversion control component 200 further includes a PWM controller 210. The MCU control component 300 also includes an MCU power supply circuit 310, an internal memory 320, a timer 330, a calculator 340, and a processor 350. The PWM controller 210 is coupled to the MCU power supply circuit 310. After the PWM controller 210 is started, the MCU power supply circuit 310 is synchronously activated. In the MCU control component, the MCU power supply circuit 310 is coupled to the internal memory 320, the timer 330, the calculator 340, and the processor 350 respectively, that is, the activation of the MCU power supply circuit 310 will drive each other element in the MCU control component 300. The device starts synchronously. Specifically, when the switch control component 100 is turned on, the mains input voltage is passed through the switch control component 100 to power up other portions of the intelligent control device of the lighting system. Furthermore, the PWM controller 210 in the post-stage constant voltage constant current power conversion control component 200 will be quickly activated as the input voltage is powered up. Preferably, the effective starting time will be controlled within 200ms to cope with the limit operation time interval value of the manual switch button. If the startup is too slow, the LED load will not respond in the fast switch, and the LED cannot be illuminated. After the PWM controller 210 is started, the MCU power supply circuit 310 receives the startup information of the PWM controller 210 and starts synchronously. Accordingly, the MCU control component 300 completes the synchronous startup.

After the MCU control component 300 is started, its internal components are synchronously started. At this time, the MCU control component 300 can read the LED status information stored in its internal memory 320 to control the working state of the LED load. . In the embodiment of the present invention, the MCU control component 300 generates a control signal by reading the LED state information in the internal memory 320, and then sends the control signal to the LED light source load control component 400 to implement the LED load. control. Further, the LED light source load control component 400 can control the LED load as a general illumination function, and the LED load will directly operate in the constant current mode based on the constant current function of the constant voltage constant current power conversion control component 200, and no longer PWM dimming output, which reduces the design cost of the system and realizes the design of economical smart lamps. Correspondingly, the LED light source load component 400 can also control the LED load as a dimming color mixing and color mixing function, and the LED load will be based on the constant voltage function of the constant voltage constant current power conversion control component 200 through the linear constant current component. In order to realize the control mode of the constant current mode, the PWM dimming function is realized by the MCU control component 300 outputting PWM signals of different duty ratios. The various loads provided by the embodiments of the present invention can also be combined in an additive manner to obtain a plurality of different LED states, which greatly enrich the color type of the LED.

In the embodiment of the present invention, when the storage state of the MCU control component 300 of the illumination system is used to store the LED state information, the preset LED status information may be stored, and the LED state whose memory working time exceeds the preset duration may be stored. information. In addition, the storage function of the MCU control component 300 can also memorize the current LED status information by receiving a custom setting signal input from the outside world.

Specifically, in the embodiment of the present invention, the timer 330 in the MCU control component 300 can be used to time the duration of the current working mode of the LED load to obtain the timing duration T _N . The difference between the T _N and the preset time length T _SET within the MCU control component 300 is further calculated. If the difference is greater than zero, the current LED status information is written to the internal memory 320 of the MCU control component 300 to state lock the current LED status information. If the difference is not greater than 0, the preset LED status information is written to the internal memory 320.

In a preferred embodiment, the current operating state of the LED load can be marked as LED state 1. Furthermore, during the entire process of the input voltage being electrically turned on, the output state of the MCU control component 300 will always control the operating mode of the LED state 1. At the same time, the MCU internal timer 330 will time the duration of the operating mode of the LEDs in different states. Correspondingly, in the embodiment of the present invention, the timing duration of the LED state 1 working mode is marked as T ₁ . At this time, the calculator 340 coupled to the timer 330 in the MCU control component 300 can be compared with the preset time length T _SET in the MCU control component 300 according to the timing result T ₁ in the timer 330. The difference between the two. After the comparison result is obtained, the LED status information corresponding to the result is sent to the processor 350 coupled to the calculator 340 according to the difference between the two. Specifically, when the difference is greater than 0, indicating that the timing of the LED state 1 working mode is greater than the preset length of time within the MCU, the logic information of the LED state 1 may be written into the internal memory 320 by the processor 350. To state the status of the LED status 1 information. When the difference is not greater than 0, indicating that the timing of the LED state 1 working mode is less than or equal to the preset length of time within the MCU, the preset LED state information is written into the internal memory 320 by the processor 350. The preset status information is locked. At this time, corresponding LED status information has been stored in the internal memory 320 of the MCU control component 300. In addition, in the embodiment of the present invention, if there is no memory inside the MCU control component 300 or when the internal memory storage capacity is insufficient, and the current LED state information to be memorized cannot be stored, a corresponding memory may be added therein to realize The above memory storage function. In the embodiment of the present invention, the "LED state 1" is merely an example, and the embodiment of the present invention does not specifically limit this.

In the embodiment of the present invention, when the input voltage is disconnected, the MCU control component 300 and the constant voltage constant current power conversion control component 200 will be quickly powered down and no longer operate. Specifically, the PWM controller 210 can control the constant voltage constant current power conversion control component 200 to complete the power down operation when the input voltage is off. Subsequently, the MCU power supply circuit 310 receives the power-down information of the PWM controller 210 and completes the synchronous power-down, thereby causing the MCU control components to be powered down synchronously. During this process, the switching response speed of the MCU control component 300 is inversely proportional to its power-down maintenance time. The longer the power-down maintenance time, the slower the response speed of the switch, and vice versa. In the embodiment of the present invention, the power-down maintenance time of the MCU control component 300 needs to be as short as possible to meet the response speed requirement of the fast switch.

In a preferred embodiment, after the input voltage is powered up again, the MCU control component 300 will directly read the LED status information stored in its internal memory 320 to control the mode of operation of the current LED. If the LED state 1 duration R ₁ of the previous stage is greater than the preset time length T _SET , the intelligent control device of the current lighting system will operate in the LED state 1 mode. The function of repeating the last LED state provided by the embodiment of the present invention is a memory locking function of the intelligent control device of the illumination system. On the other hand, if the LED state 1 duration T ₁ of the previous stage is not greater than the preset time length T _SET , the intelligent control device of the current lighting system will operate in the working mode of the preset LED. The function of switching to a predetermined LED state provided by the embodiment of the present invention is a switch control function of the intelligent control device of the illumination system.

In addition, in a preferred embodiment, after sequentially starting different LED loads according to the control information, the intelligent control device of the illumination system can also receive a control signal input by the outside world, and adjust the LED of the illumination system according to the received control signal. Load to the specified combined state and light up. Referring to FIG. 2, an embodiment of the present invention further provides an infrared receiving control component 500, which is an optional component in an intelligent control device of the lighting system. When the infrared receiving control component 500 is used in an intelligent control device of the lighting system, it is coupled to the MCU control component 300. At this time, the infrared receiving control component 500 can receive the infrared transmitting encoded signal emitted by the infrared information transmitting component of the outside, and effectively detect the infrared transmitting encoded signal. When the valid coded signal is detected, it is forwarded to the MCU control component 300. When the MCU control component 300 receives the valid coded signal, it can decode it, and then convert it into a logic signal capable of controlling the LED load, and carry the logic signal in the control information and send it to the LED light source load control. Component 400. The LED light source load control component 400 will adjust the LED load of the illumination system to the combined state specified by the infrared emission coded signal according to the logic signal and illuminate.

The embodiment of the present invention further provides an infrared signal transmitting component 600 (see FIG. 3). The infrared signal transmitting component 600 is coupled to the infrared receiving control component 500 for transmitting an infrared transmitting encoded signal to the infrared receiving control component 500. Specifically, FIG. 4 is a schematic diagram of a custom mode setting of an intelligent control device of a lighting system according to an embodiment of the present invention. In a preferred embodiment, as shown in FIG. 4, the infrared receiving control component 500 will continuously detect the transmitted encoded signal of the infrared signal transmitting component 600 during any of the electrical conduction of the input voltage. When the infrared receiving control component 500 detects the correct effective transmit encoded signal, the signal is sent to the MCU control component 300. The MCU control component 300 will further decode it and convert it into a logic signal capable of controlling the state of the LED to specifically control the current state of the LED. Furthermore, if the user likes the LED state, the user-defined mode setting can be performed by the infrared signal transmitting component 600, and the LED state information is sent to the infrared receiving control component 500 through the infrared signal. After receiving the signal, the infrared receiving control component 500 notifies the MCU control component 300 to store the status information of the current LED, and the MCU control component 300 stores the current LED state information according to the notification. In this way, if the user wants to obtain the LED status again, there is no need to repeat the operation again, and it is only necessary to directly call the custom mode or switch to the LED state by switching, which is not only simple but also convenient. The settings can be customized according to the user's preferences. In addition, the user can maintain the length of the working time of the favorite LED state is greater than the preset length of time, then when the user powers up again next time, the system will directly lock in the working mode of the LED state without The switch is switched to find this state, which provides great convenience for the user.

Among them, the linear constant current component can be a linear constant current integrated control circuit commonly used in the market, or a linear constant current circuit formed by a discrete device.

When the user activates the switch control component 100 for the first time, the input voltage is powered by the switch control component 100 to the other parts of the smart light fixture. At this time, the illumination mode of the smart luminaire is the white light that is preset internally. At the same time, the MCU control component 300 inside the smart luminaire counts the current LED state and stores the corresponding LED state information. It is assumed that after the luminaire is illuminated for 10 minutes in a normally white light illumination mode, the user adjusts it to a combination of white light and yellow light.

The optically combined color light illumination method corresponds to the infrared coded signal. The infrared receiving control component 500 in the smart luminaire effectively detects the infrared encoded signal and transmits the detected effective encoded signal to the MCU control component 300. The MCU control component 300 decodes the received valid encoded signal into a logic signal of the LED load to switch the illumination mode of the LED load. At this point, the illumination mode of the smart luminaire can be successfully switched to the combination of white light and red light. If the user wants to illuminate the smart light fixture with the combination of white light and red light, the infrared light emitting component 600 can also transmit the corresponding infrared coded signal to the smart light fixture to perform the illumination mode. Memory lock. Further, when the user activates the switch control component 100 of the smart light fixture again, the illumination mode of the smart light fixture is a combination of white light and red light, without requiring the user to manually adjust the setting again.

The method provided by the embodiment of the present invention can memorize and store the manners of the plurality of LED load combinations that the user likes, and then, when the smart light fixture is restarted, the light fixture can be illuminated in the illumination mode that the user prefers without manual operation by the user. Improved user experience.

The white light, the yellow light, and the red light provided by the above embodiments are merely exemplified.
