The structural principle and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.

Referring to Figure 1, a sunlight conveyor and LED complementary lighting device is composed of four parts: a pan/tilt, an automatic tracking system, an optical fiber lighting device and an LED light source;

Described cloud platform comprises cloud platform daylighting plate A and glass convex lens 104 and solar panel 103 that are installed on it, and cloud platform daylighting plate A is provided with cloud platform base plate B by double-ended adjustable bar 107, and described cloud platform daylighting plate A is fixed on the U-shaped pipe frame D, and the U-shaped pipe frame D is set on the control box and the base C;

Described automatic tracking system comprises the sunlight sensor 102 that is installed on cloud platform daylighting board A, east-west direction control motor 101 and north-south direction control motor 105, and described sunlight sensor 102 is connected with control circuit module, liquid crystal display module and button module by data line , the control circuit module includes a single-chip microcomputer, the output of the single-chip microcomputer is connected to the input of the driver chip, and the output port of the driver chip is connected to the interface of the east-west direction control motor 101 and the north-south direction control motor 105; There is a positive pole of the solar panel 103; the input end of the single-chip microcomputer is configured with a potentiometer, and realizes forward and reverse and start-stop control of the east-west direction control motor 101 and the north-south direction control motor 105 according to the control signal of the single-chip microcomputer; It is L298N, and the microcontroller is STC12C5A60S2;

As shown in Fig. 2 (a), described optical fiber illuminating device is made up of plastic optical fiber 202 and optical fiber terminal diffuser 201, and described plastic optical fiber 202 adopts the PMMA type plastic optical fiber that diameter is 2mm, and described optical fiber terminal diffuser 201 is connected on the cloud platform bottom plate B by plastic optical fiber 202; Described glass convex lens 104 receives sunlight, changes the distance between the cloud platform daylighting plate A and the bottom plate B through double-ended adjustable rod 107 to adjust the glass convex lens 104 The size of the light spot, and then by moving the position of the optical fiber receiver 106 in the round hole on the base plate B of the pan/tilt up and down, left and right, the light spot can just fall to the center of the optical fiber receiver 106, and the concentrated sunlight can be guided into the plastic light guide The fiber 202 finally guides the light into the room for direct lighting through the optical fiber in a way of total reflection.

As shown in Figure 2 (b), the LED light source includes a battery 108, the positive pole of the battery 108 is connected to an energy-saving LED lamp 204 through an automatic LED lighting controller 203, and the other end of the energy-saving LED lamp 204 is connected to the negative pole of the battery 108, so The lighting controller 203 is a trigger switch, and the single chip microcomputer will automatically close when it receives a high pulse signal, and automatically disconnect when receiving a low pulse signal;

The battery 108 is also connected to a solar panel 103;

The present invention directly introduces outdoor sunlight into lighting during the daytime, and is especially suitable for occasions such as underground parking lots, museums, large shopping malls, gymnasiums, hotels, etc., and can save a large amount of power; the lighting controller 203 is a trigger switch, and the single-chip microcomputer gives it a high pulse signal to automatically Closed, automatically disconnected when receiving low pulse signal. When the light intensity is less than the set value threshold, the automatic tracking system of the sunlight conveyor stops tracking, and the single-chip microcomputer sends a control signal to make the LED lighting controller 203 connect the energy-saving LED lamp 204 with the storage battery 108, and the energy-saving LED lamp 204 can provide up to 12 hours of continuous lighting; when the light intensity is greater than the set value threshold, the single-chip microcomputer sends a control signal to make the LED lighting controller 203 cut off the connection between the energy-saving LED lamp 204 and the battery 108, and the automatic tracking system of the sunlight conveyor restarts tracking and converts to optical fiber For lighting, if a particularly bright lighting environment is required, the battery 108 and the fiber optic lighting device can work together by turning off the switch of the LED lighting automatic controller 203, so that the fiber lighting and the LED lighting run simultaneously to provide enhanced lighting for the room.

As shown in Figure 3, the optical fiber receiver 106 is funnel-shaped, and one end of the optical fiber receiver 106 is provided with a focusing hole 301 and a top cover 302, and a fiber inlet 304 and a fiber circular sleeve are arranged opposite to the focusing hole 301. Tube 303, the outer diameter of the optical fiber circular sleeve 303 is 2.5 mm, and the inner diameter is 2.1 mm.

As shown in Fig. 4, the power supply of about 12v provided by the solar panel 103 can directly provide power for the east-west direction control motor 101 and the north-south direction control motor 105. The cathode of the conductive diode D1 is connected to the positive pole of the storage battery 108, and the diode D2 is connected to the input end of the 7805 regulated power supply chip to provide a power supply of about 5V for the system. During the daytime, the solar panel 103 uses part of the electric energy emitted by the entire system for consumption, and the remaining part is stored in the battery 108;

When the light intensity is very weak, due to the unidirectional conduction effect of the unidirectional conductive diode D1, the storage battery 108 cannot supply power to the capacitors C6, C7, C8, C9, and C10, and the two control motors cannot operate due to lack of power, but can be stabilized by The power supply chip 7805 continues to supply power for the single-chip microcomputer to ensure the normal operation of the single-chip microcomputer program.

When the light is good, the output voltage of the solar cell panel 103 is higher than the charging voltage of the storage battery 108, so the solar cell panel 103, the unidirectional conductive diode D1, the storage battery 108 and the control circuit module form a loop, realizing the charging and charging of the storage battery 108. The power supply of the control circuit module realizes the tracking of sunlight; under the condition of poor illumination, the voltage of the battery 108 is higher than the voltage of the solar panel 103, because the unidirectional conduction diode D1 has unidirectional conductivity, so the battery 108 is cut off from the solar energy. The current in the direction of the battery panel 103 reduces the loss of the battery 108 and protects the solar panel 103 .

As shown in Figure 5, the principle of STC12C5A60S2 single-chip microcomputer and L298N driver chip to drive and control the motor is: P3.4, P3.5, P3.6, and P3.7 pins of the single-chip microcomputer are connected to 5 (IN1), 7 (IN2) of the L298N driver chip respectively. ), 10 (IN3), 12 (IN4) pins, which send control signals to control the work and stop of the east-west direction motor 101 and the north-south direction motor 105.

The 4-pin Vss of the L298N driver chip is directly connected to the positive pole of the solar panel 103, and the solar panel 103 is used to provide power for two control motors, 2 (OUT1), 3 (OUT2), 13 (OUT3), 14 (OUT4) pins The output terminals are connected to the positive and negative poles of the east-west direction control motor 101 and the north-south direction control motor 103 respectively, and the motors are controlled to rotate forward or reverse or stop according to the instructions provided by the single-chip microcomputer. Diodes D ₅ , D ₆ , D ₇ , D ₈ , and D ₁₂ , D ₁₃ , D ₁₄ , and D ₁₅ are freewheeling diodes, and light-emitting diodes D ₉ , D ₁₀ , D ₁₁ , and D ₁₆ are used to display the status of the two motors respectively. In the case of positive and negative rotation, J6 (that is, CON4) is a 4-port connection terminal, from top to bottom 1-4 are respectively externally connected to the positive and negative poles of the east-west direction control motor 101 and the north-south direction control motor 103.

As shown in Figure 6, the present invention judges the irradiation situation of sunlight by sunlight sensor 102, and the resistance value of the photosensitive resistance element installed on sunlight sensor 102 becomes approximately linear change in a certain range for different light intensity, and sunlight sensor 102 will photosensitive The analog quantity generated by the component is transmitted to the P1 port (P1.0～P1.7) of the STC12C5A60S2 single-chip microcomputer through the data line. port (P1.0～P1.7), the conversion speed can reach 100KHz, because the 8-way A/D converter of the single-chip microcomputer is a voltage input type, and the analog quantity provided by the photosensitive element is a current signal, at P1.0～P1. The 7 ports are externally connected with 8 potentiometers (ie, variable resistors), and the current signal provided by the sunlight sensor 102 is converted into a voltage signal, and then processed by the signal amplification circuit, filter circuit, and comparison circuit, and provided to the single-chip microcomputer.

Potentiometers are used instead of resistors, because the external light intensity varies greatly in different environments and regions, and the input amount of the sunlight sensor 102 to the single-chip microcomputer can be adjusted by simply adjusting the 8 potentiometers, so that the control system can be calibrated to a certain extent. The STC12C5A60S2 single-chip microcomputer processes the digital signals provided by the sunlight sensor 102 and related circuits through the internal program, and uses the integrated chip L298N to drive and control the motor, so that the light plate A of the cloud platform of the sunlight conveyor is always facing the sunlight. ,

Then use the glass convex lens 104 to condense the sunlight. The plane of the cloud platform lighting plate A and the plane of the platform base B must be placed in parallel, and the focus of the glass convex lens 104 on the platform base B is the center of the circle. Open about 6mm Circular hole, the optical fiber receiver 106 is installed on the circular hole of the pan-tilt bottom plate B, by adjusting the double-ended adjustable rod 107, changing the distance between the pan-tilt daylighting plate A and the bottom plate B to adjust the glass convex lens 104 Spot size, adjust the spot diameter to about 2mm.

By moving the position of the optical fiber receiver 106 in the round hole on the pan-tilt bottom plate B up and down, left and right, the light spot can just fall on the center position of the optical fiber receiver 106, because the beginning of the optical fiber is installed in the center of the optical fiber receiver 106, This is equivalent to the light spot hitting the light-receiving surface of the optical fiber, so that the concentrated sunlight is guided into the plastic optical fiber 202, and then the light is guided into the room through the optical fiber in a way of total reflection for direct lighting. Because sunlight is converged to the light-gathering interface area with a diameter of 2 mm through the glass convex lens 104, the light-gathering area ratio reaches (π*50 ² )/(π*1 ² )=2500 (times), resulting in the temperature of the light-gathering interface area It rises sharply, and can reach a maximum of about 120°C, which is close to the melting point of the plastic optical fiber. Therefore, it is inevitable that the plastic optical fiber is in a molten state. The upper surface is closely connected with the aluminum base plate B of the gimbal, thus forming a huge radiator, which greatly reduces the temperature of the light-gathering area to about 70°C, which is within the normal working temperature range of plastic optical fibers.

After testing, the terminal optical fiber of the sunshine conveyor is always in a bright state, and the 16 optical fibers can provide the luminous flux equivalent to two 60W fluorescent lamps; at the same time, since the sunlight is always directly shining on the solar panel 103, the efficiency of solar power generation is significantly improved. For the solar panel 103, the efficiency of solar power generation can be increased to more than 22%. Part of the energy generated by the solar panel 103 provides power for the control system and the motor, and most of it is stored in the lead-acid battery for night LED lighting.

As shown in the structural diagram of Figure 7, the manual control board is composed of a liquid crystal display LCD12864, a 9-pin serial port plug UART, and 6 buttons S1-S6. Through the 12864 liquid crystal display, you can observe the current operating conditions of the sunlight conveyor and the LED complementary lighting device at any time. By operating the button S1, you can set the control system to two modes: manual and automatic control. In the automatic control mode, the device can automatically find the position of the sun. Azimuth, finally make the sunlight shine directly on the daylighting panel of gimbal A; stop automatic tracking in manual mode, press S2 to make the gimbal move north, press S5 to make the gimbal move south, press S4 down to make the gimbal move Move to the west, press S6 to make the gimbal move to the east, and manually adjust the gimbal to make the daylighting panel A of the gimbal face the sunlight, which is used to correct the automatic tracking situation. After pressing and holding S6 for more than 30 seconds, you can enter the interface for setting the light intensity threshold, press S2 to increase the original threshold, and press S5 to decrease the original threshold, so as to set the appropriate light intensity according to the actual lighting needs threshold.

A control method for a sunlight conveyor and LED complementary lighting device. First, the intensity of sunlight is converted into an electrical signal by a photoelectric sensor, and then divided into 256 levels from 0 to 255, where 0 and 255 correspond to no light and the strongest The sunlight intensity of the sun, and then display the lighting situation of the pan-tilt daylighting panel A when the system is initially started on the liquid crystal in digital form through the liquid crystal display. When the sum of the displayed light intensity values on the liquid crystal display is greater than the set threshold, The system recognizes that the current situation is daytime, and first drives the north-south direction control motor 105 to rotate to determine the position of the sun in the north-south direction, and then drives the east-west direction control motor 101 to rotate to further determine the position of the sun in the east-west direction, so that the sunlight reaches the cloud platform daylighting panel The light intensity of A is the highest, that is, the sunlight irradiates the glass convex lens 104 and the solar panel 103 vertically.

Then by utilizing the convex lens 104 to gather sunlight to the center hole of the optical fiber receiver 106, the initial end of the plastic optical fiber 202 is inserted into the center hole of the fiber receiver 106, and the principle of total reflection of the optical fiber is used to guide the room for illumination. The solar panel 103 is always irradiated by sunlight vertically, and the efficiency is increased by more than 80%: the solar panel provides about 12v of power, which can directly provide power for the east-west direction control motor 101 and the north-south direction control motor 105; the power supply of the solar panel 103 and the microcontroller control board The circuit is connected, and the voltage is converted to 5v by a 7805 voltage regulator circuit to provide power for the single-chip microcomputer. At the same time, it is also connected to the lead-acid battery 108 through the single-chip microcomputer control board to charge and store energy for LED lighting in rainy days and nights. When the sum of the light intensity values shown on the liquid crystal display is less than the set threshold value, it is considered that the current situation is rainy or night, and the automatic control system stops tracking, while the LED lighting automatic controller 203 automatically connects the storage battery 108 to utilize the energy-saving LED Provide lighting, when the light intensity is greater than the set threshold, it will automatically switch to fiber optic lighting.
