It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] Please refer to Figure 1-2 As shown, a solar energy storage box applied to a lamp comprises a box body 1, wherein the box body 1 is provided with a wire 2 for supplying power to the lamp, and the box body 1 is provided with a battery 3 connected to the wire 2, and a photovoltaic panel;

[0018] Also included is a circuit part, the circuit part includes:

[0019] The main control unit U1 has a detection end connected to the collector of the transistor Q2, the emitter of the transistor Q2 is grounded, and the base is connected to the photovoltaic port PV+ through a resistor R1, and the photovoltaic port PV+ is used to connect the photovoltaic panel. The photovoltaic port PV+ is also connected to the drain of the P1-P3 switch tube, and the source of the P1-P3 switch tube is connected to the battery port B+, and the gate is connected to the output control end of the main control unit U1, and the battery port B+ is used to connect to the battery 3.

[0020] When there is light during the day, the photovoltaic panel receives solar energy. At this time, the photovoltaic port PV+ supplies power to the base of the transistor Q2, so that the transistor Q2 is turned on. Then the detection end pin 7 of the main control unit U1 is grounded through the transistor Q2 to pull down the voltage. At this time, the pin is a signal 0, which is determined to be a daytime state. The control output end pin 8 of the main control unit U1 sends a signal to turn on the P1-P3 switch tube, so that the photovoltaic panel is connected to the battery through the switch tube for charging, so that the battery 3 continuously supplies power to the lamp through the wire;

[0021] At night, the pin 7 of the main control unit U1 is signal 1, and the pin 8 turns off the switch tube. In this way, the energy storage box of the present application can work outdoors without being connected to the mains.

[0022] In this embodiment, a sensor connection port YS1 is also included, which is used to connect to the sensor. Its power supply end is connected to the output end of the main control unit U1 through a resistor R6, its signal end is connected to the signal detection end of the main control unit U1, and its ground end is connected to the resistor R6 through a capacitor C6. RAP is a control voltage. When there is a sensing function, the voltage is output to power the sensor to achieve the purpose of power saving. RA is a sensing signal. When there is a sensing signal, RA is 1, and when there is no one, RA is 0. Pin 16 of the main control unit U1 receives the RA signal. When RA is 1, the pin 9 of the main control unit U1 controls the output signal to be high-lighted. When RA is 0, the pin 9 of the main control unit U1 controls the output signal to be off.

[0023] In this embodiment, a remote control connection port IR1 is also included, which is used to connect to the remote control module to control the energy storage box by remote control. Its power supply end is connected to the output end of the main control unit U1 through a resistor R5, and its signal end is connected to the signal receiving end of the main control unit U1 to receive the remote control signal. IR-EN is the remote control voltage control pin, and the single-chip microcomputer controls the output to achieve power saving. IR is the remote control signal pin. Pin 15 of the main control unit U1 receives the remote control signal and controls the corresponding remote control signal.

[0024] In this embodiment, a key unit SW-1 / SW-2 is also included. The key unit SW-1 / SW-2 is connected to the main control unit U1, and the main control unit U1 is controlled by keys to activate corresponding functions.

[0025] In this embodiment, a boost unit U2 is also included;

[0026] It also includes an inductor L1-2, one end of which receives the voltage of the battery 3, and the other end of which is connected to a diode D5, the diode D5 is connected in parallel with a diode D4, and the common end of the diode D5 and the diode D4 is provided with an output end for powering the lamp;

[0027] The other end of the inductor L1-2 is connected to the drain of the N3-4 switch tube, and the source thereof is grounded through a resistor R16. The resistor R16 is connected in parallel with a resistor R15. The gate of the N3-4 switch tube is connected to the control end of the boost unit U2.

[0028] The common terminal of the resistor R16 and the resistor R15 is connected to the collection terminal of the boost unit U2.

[0029] In the initial state, the N3-4 switch tube receives the signal from the boost unit U2 and turns on. The battery voltage passes through the inductor L1-2, the switch tube, and the resistors R15 and 16 to the ground. At this time, the current of the inductor increases linearly, and the voltage collected by the resistor R16 also increases linearly and is fed back to the collection end of the boost unit U2 until the CS voltage reaches 0.25V and the switch tube is turned off. Then the inductor L1-2 releases the current and supplies power to the output end through the freewheeling diodes D4 and D5, which in turn increases the output voltage, allowing the lamp beads to have better luminous power.

[0030] In this embodiment, it also includes a switch tube N1, whose source is grounded, whose drain is connected to the output end of the battery 3, and whose gate is connected to the main control unit U1;

[0031] The gate of the P4-6 switch tube is connected to the drain of the N1 switch tube, the source is connected to the output end of the battery 3, and the drain is connected to the VDD end of the boost unit U2 through the resistor R14.

[0032] Only after the main control unit U1 sends the EN signal to turn on the N1 switch tube, the P4-5 switch tube will be turned on, and the battery voltage can supply power to the VDD of the boost unit U2 through the resistor R14, playing a control role, and can also disconnect the boost circuit to save power.

[0033] In this embodiment, a voltage conversion unit Q3 is also included, whose input end is connected to the output end of the battery 3, whose output end outputs a voltage, and the output end is connected to the source of the P1 switch tube, whose gate is connected to the main control unit U1, and whose drain outputs a signal FB;

[0034] The signal FB is connected to the diode D5 via the diode ZD1, and the P1 switch is controlled to conduct by sending a PWM signal to control the signal FB, thereby achieving dimming of the lamp.
