Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0030] The output end of control module is connected with the control end of current controller one and current controller two respectively.

[0031] The grid access management module comprises an isolation voltage reducer, a current controller three and a current detector two, the input end of the isolation voltage reducer is connected with external mains, the output end is connected with the input end of the current controller three, the output end of the current controller three is connected with the input end of the LED power module, the detection end of the current detector two is arranged at the connection point of the output end of the current controller three and the input end of the LED power module, and the output end of the current detector two is connected with the input end of the control module.

[0032] The output end of the control module is connected with the control end of the current controller two.

[0033] The control module is a microcontroller.

[0034] The energy storage device is a super capacitor or a storage battery.

[0035] The microcontroller monitors the power size of the glass side and the grid side, controls and coordinates the power proportion of the power generation glass and the grid, ensures the balance of input and output, the control module preferentially obtains electric energy from the power generation glass, and for lack of electric energy, the control module obtains electric energy from the grid to fill the vacancy. The electric energy obtained through the above two ways is mixed and input into the LED power circuit to drive the LED to emit light. The control circuit monitors the real-time output power of the power generation glass and controls the input power of the mains to ensure that the electric energy of the power generation glass is maximized and the total power meets the requirements, thereby reducing the power consumption cost.

[0036] Through the technical scheme, when power is started, the current controller three 3 is completely opened to ensure that the LED has sufficient electric energy to work normally. After the circuit works stably, the current controller two 2 is disconnected, the current controller one 1 is connected, the electric energy output by the power generation glass is completely loaded on the load resistance, the microcontroller starts the current detector one 1, and the current flowing through the load matching resistance is measured. The power value is calculated according to the formula W 玻璃 =R*I 2 The value is the maximum output power of the power generation glass at this moment. Assuming that the input power of the grid side is W 电网 , the power of the lamp is W 总 , and W 电网 = W 总 -W 玻璃 .

[0037] The microcontroller calculates the input power of the grid end through the above formula, and adjusts the input power of the grid side to the calculated value through the current controller three 3 and the current detector two 2.

[0038] When the ambient light condition changes, the energy storage device provides short-time energy output, alleviates the fluctuation of the light-emitting diode (LED) caused by the power fluctuation of the power generation glass, and the microcontroller quickly adjusts the input current of the power grid to ensure that the sum of the power of the power generation glass and the power grid is equal to the total power of the lamp, so that the lamp emits light stably and normally during the process.

[0039] The current control component is used to control the size and direction of the current, and can control the output power of the passage while preventing the reverse flow of the current.

[0040] Based on the above technical solutions, in actual application, as shown in the circuit principle diagram: Figures 3-7

[0041] The circuit of the lighting device is as shown in the drawing, which mainly includes a power generation glass circuit, Figure 3 a isolation and voltage reduction circuit, Figure 5 a constant current LED circuit, Figure 4 and a microcontroller (single-chip microcomputer) circuit. Figure 6 Figure 7

[0042] The isolation and voltage reduction circuit

[0043] 220V alternating current is reduced to 24V direct current through the switching power supply circuit, and the MOS tube Q3 controls the size of the current. R17, U5 and R16 form a current detection circuit.

[0044] The power generation glass circuit

[0045] Power detection: R4 is a load resistor, R10 is a sampling resistor, and U3 is a current detection device. When Q2 is closed and Q1 is disconnected, the output voltage of U3 can be calculated to calculate the current I flowing through R10 and R4, and the real-time output power of the power generation glass can be calculated according to the formula W=I 2 *R.

[0046] The voltage boosting circuit: D2 is a diode to prevent reverse current, and the super capacitor can store a part of the electric energy, which plays a role in voltage stabilization when the output of the power generation glass sharply decreases. U1 is a voltage boosting chip that boosts the output voltage of the glass to 24V constant voltage and provides a constant current for the LED circuit.

[0047] The constant current LED circuit

[0048] U2 is a voltage boosting constant current driving chip that further boosts the 24V to provide a stable current for the LED.

[0049] The microcontroller circuit

[0050] 24V is reduced to 3.3V through U4 to supply power to the single-chip microcomputer U7, and the single-chip microcomputer U7 controls the entire system to work.

[0051] ​​​SW1, SW2, SW3 are switch control signals, ADC1, ADC2 voltage acquisition signals, and the corresponding circuit flows through the current size.

[0052] Power measurement: SW1 low level, SW3 high level, at this time Q1 is disconnected, Q2 is closed, the single-chip microcomputer calculates the power on R4 power resistor through ADC1 acquisition signal, which is the maximum power output by the power generation glass at this moment

[0053] Electric energy mixing: W 电网 = W 总 - W 玻璃 The single-chip microcomputer calculates the output power of Q3 through the above formula, calculates the current size flowing through R17 from the power value, and then controls Q3 through SW2 to set the current to the calculated value. At this time, the electric energy input by the combination of the alternating current power supply and the power generation glass provides illumination for the LED.
