[0032] See Figure 1 The lamp holder 100 provided in this application embodiment includes: a main control unit 102, a battery unit 101, and a light-emitting unit 103.

[0033] The battery unit 101 is connected to the main control unit 102 and the light-emitting unit 103 through a power supply line, and the battery unit 101 also includes a charging port 1011, which is used to connect to the photoelectric conversion module.

[0034] In one embodiment, the battery cell 101 is provided with at least one battery Ba that is rechargeable and dischargeable.

[0035] In one embodiment, the battery unit 101 is connected to the main control unit 102 and the light-emitting unit 103 via a power supply line, thereby providing power to the main control unit 102 and the light-emitting unit 103.

[0036] In one embodiment, the photoelectric conversion module can characterize a device or apparatus capable of converting light energy into electrical energy, such as a solar panel.

[0037] In one embodiment, the specific form of the charging port 1011 is matched with the configuration of the photoelectric conversion module to be connected.

[0038] The main control unit 102 is connected to the light-emitting unit 103 and is used to control the light-emitting unit 103 to turn on or off. The main control unit 102 includes a communication port 1021, which is used to connect to the working indicator module through a communication line.

[0039] In one embodiment, the main control unit 102 may characterize a device or component capable of configuring lighting control logic to control the light-emitting unit 103 to turn on or off, such as an MCU (microcontroller unit).

[0040] In one embodiment, the working indicator module can characterize a device or equipment that can at least indicate the working status information of the battery unit 101 and / or the light-emitting unit 103 in the indicator head 100, for example, a pull box having a power display light module and a light control level display light module.

[0041] The lamp head 100 provided in this embodiment includes: a main control unit 102, a battery unit 101, and a light-emitting unit 103. The battery unit 101 is connected to the main control unit 102 and the light-emitting unit 103 through a power supply line, and the battery unit 101 also includes a charging port 1011 for connecting to a photoelectric conversion module. The main control unit 102 is connected to the light-emitting unit 103 and is used to control the light-emitting unit 103 to turn on or off. The main control unit 102 also includes a communication port 1021 for connecting to a work indicator module through a communication line. Thus, the lamp head 100 provided in this embodiment can be mounted on a solar lamp, and the rechargeable battery unit 101 configured in the lamp head 100 can supply power to the light-emitting unit 103 under the control of the main control unit 102 to achieve lighting. Since the lamp head 100 is directly configured with the battery unit 101, the battery unit 101 does not have a long power transmission line, so the power loss of the lamp head 100 is reduced, thereby improving the energy utilization rate of the battery unit 101.

[0042] In one embodiment, see Figure 2The battery unit 101 also includes a charging protection chip U1 and a battery Ba. The battery Ba is connected to the charging port 1011 and the charging protection chip U1 to form a charging protection circuit. The charging port 1011 includes a photovoltaic interface and a diode D1. The photovoltaic interface is connected to the battery Ba through the diode to form a charging path for charging the battery Ba. The photovoltaic interface is used to connect to the photoelectric conversion module.

[0043] In one embodiment, the charging protection chip U1 can be of model XB5352A, which can provide overcurrent protection, overvoltage protection, and overcharge protection for the battery Ba. For example, the positive terminal interface of the battery Ba ( Figure 2 The 1 and 3 interfaces of the battery Ba are connected to the VDD pin of the charging protection chip U1 through the current-limiting resistor r1. The negative interface of the battery Ba ( Figure 2 The 2nd and 4th interfaces of the battery are connected to the GND pin of the charging protection chip U1. The positive and negative interfaces of the battery Ba are also connected through the filter capacitor r1.

[0044] In one embodiment, diode D1 can prevent reverse flow of electrical energy from battery Ba.

[0045] In one embodiment, the charging port 1011 includes an ambient light detection circuit E1. The ambient light detection circuit E1 includes a first resistor R1, a second resistor R2, a first capacitor C1, and a first signal output interface OUT1. One end of the first resistor R1 is connected to the charging path, and the other end of the first resistor R1 is grounded through the second resistor R2. The first signal output interface OUT1 is connected between the first resistor R1 and the second resistor R2. The first signal output interface OUT1 is also grounded through the first capacitor C1 and is connected to the main control unit 102. The ambient light detection circuit is used to transmit a first voltage divider signal GK obtained according to the voltage of the charging path to the main control unit 102, so that the main control unit 102 determines the ambient light intensity according to the first voltage divider signal GK and performs lighting control according to the preset lighting control logic.

[0046] In one embodiment, the first capacitor C1 can achieve filtering and noise reduction, making the first voltage divider signal GK more stable.

[0047] In one embodiment, the voltage on the charging path of the photoelectric conversion module changes due to changes in illumination, which in turn causes the first voltage divider signal to change. The main control unit 102 can determine the ambient light intensity based on the change in the first voltage divider signal, thereby identifying whether the current environment is daytime or nighttime, and can then automatically switch between the daytime lighting mode and the nighttime lighting mode configured based on the preset lighting control logic (built-in algorithm) of the main control unit 102.

[0048] In one embodiment, see Figure 3The lamp holder 100 may also include an infrared probe PIR1; the infrared probe PIR1 is connected to the main control unit 102 and is used to acquire the infrared sensing signal PIR and transmit the infrared sensing signal PIR to the main control unit 102, so that the main control unit 102 can determine the human body sensing information based on the infrared sensing signal PIR and perform lighting control according to the preset lighting control logic.

[0049] In one embodiment, the main control unit 102 controls the lighting based on the infrared sensing signal PIR and preset lighting control logic, such as controlling the lights to turn on when someone comes and turn off when someone leaves.

[0050] In one embodiment, the main control unit 102, through environmental sensing devices or circuits such as infrared probe PIR1 and ambient light detection circuit E1, and in conjunction with preset lighting control logic, can control the light-emitting unit 103 according to environmental changes to achieve adaptive lighting or turning off of the light, as well as adjustment of lighting brightness or color temperature.

[0051] In one embodiment, see Figure 4 The lamp holder 100 may further include a power detection circuit; the power detection circuit includes a third resistor R3, a fourth resistor R4, and a second signal output interface OUT2; one end of the third resistor R3 is connected to the battery Ba to receive the battery Ba voltage, and the other end of the third resistor R3 is grounded through the fourth resistor R4; the second signal output interface OUT2 is connected between the third resistor R3 and the fourth resistor R4, and is connected to the main control unit 102. The power detection circuit is used to transmit a second voltage divider signal BK obtained based on the battery Ba voltage to the main control unit 102, so that the main control unit 102 outputs a power display control signal to the communication port 1021 based on the second voltage divider signal BK. The power display control signal BK is used to control the working indicator module to display the power level. Thus, this embodiment provides a lamp holder 100 that has the functions of power detection and controlling the working indicator module to display power information.

[0052] In one embodiment, see Figure 5 The light-emitting unit 103 includes a switch control unit E2 and a light control unit E3. The light control unit E3 includes a current control module E31 and a light-emitting diode D2. The anode of the light-emitting diode D2 is connected to the battery unit 101, and the cathode of the light-emitting diode D2 is connected to the switch control unit E2 through the current control module E31. The current control module E31 is a current shunt circuit composed of at least one resistor (e.g., Figure 5 The current shunt circuit consists of three resistors Ra, Rb, and Rc connected in parallel; the switch control unit E2 includes at least one MOSFET (e.g., Figure 5Two MOSFETs Q1 and Q2 are shown, along with a fifth resistor R5 and a sixth resistor R6. The control terminal of the MOSFETs is connected to the main control unit 102 through the fifth resistor R5. The first path terminal of the MOSFETs is connected to the current control module E31, and the second path terminal of the MOSFETs is grounded and connected to the control terminal of the MOSFETs through the sixth resistor R6.

[0053] For example, see Figure 5 In this embodiment, the current in the light-emitting unit 103 is triggered by the positive terminal of the battery unit 101, flows through the anode of the light-emitting diode D2, through the light-emitting diode D2, then through the three parallel resistors Ra, Rb, and Rc, and finally grounded through the path formed by the conduction of MOSFETs Q1 and Q2. When the main control unit 102 sends a high-level LED control signal, MOSFETs Q1 and Q2 conduct, and the light-emitting diode D2 is lit, with its brightness depending on the magnitude of the current flowing through it. When the main control unit 102 sends a low-level LED control signal, MOSFETs Q1 and Q2 conduct, and the light-emitting diode D2 is turned off. In addition, the brightness of the LED can be controlled by the switching and feedback regulation of the MOSFETs, combined with the current shunting of the parallel resistors. Among them, the fifth resistor R5 acts as a pull-up resistor, which can prevent the voltage output by the main control unit 102 from being too high and burning out the MOSFETs. The sixth resistor R6 acts as a pull-down resistor, which can prevent the diode in the MOSFET from conducting, thus preventing the MOSFET from malfunctioning or becoming unstable. The three parallel resistors Ra, Rb, and Rc mainly function in the circuit to shunt, limit, and participate in feedback regulation. They adjust the total current flowing through the LED D2 by combining in parallel, thereby controlling the brightness of D2. At the same time, they limit the maximum current flowing through the LED D2 to prevent excessive current from damaging the LED D2.

[0054] In one embodiment, multiple resistors in the current control module E31 can form a resistor divider network to set the reference current of the light-emitting diode D2 and control its brightness.

[0055] In one embodiment, when the switch control unit E2 includes multiple MOSFETs, the operating temperature of each MOSFET can be reduced to avoid device damage.

[0056] In one embodiment, the lamp holder 100 may further include a first switch assembly; the first switch assembly is connected to the main control unit 102 and is used to trigger and output a lighting control signal to the main control unit 102, so that the main control unit 102 performs lighting control according to a preset lighting control logic. For example, the main control unit 102 can control the lighting unit 103 to turn on or off, and / or adjust the lighting level, etc., according to the preset lighting control logic and the lighting control signal.

[0057] In one embodiment, the battery cell 101 includes a first voltage conversion unit, which is used to convert the battery voltage Ba provided by the battery Ba in the battery cell 101 into a first operating voltage.

[0058] In one embodiment, the first voltage conversion unit is connected to the main control unit 102 and is used to power the main control unit 102 with the first operating voltage.

[0059] In one embodiment, a first voltage conversion unit is connected to an infrared probe PIR1 and is used to power the infrared probe PIR1 with a first operating voltage.

[0060] In one embodiment, the first voltage conversion unit may include a voltage regulator chip. The voltage regulator chip may be, for example, a DC-DC voltage regulator chip or an LDO (low dropout linear regulator). The DC-DC voltage regulator chip can perform voltage boost or buck conversion; the LDO (low dropout linear regulator) can perform buck conversion. See also... Figure 6 Taking the voltage regulator chip U2 in the first voltage conversion unit as an LDO as an example, the VIN pin of the LDO is connected to the battery Ba to receive 5V (i.e., the voltage of the battery Ba). The VIN pin of the LDO is also grounded through capacitor C2 to achieve voltage regulation and filtering. After the LDO performs voltage reduction processing, it outputs 3V (i.e., the first working voltage) through its VOUT pin. The LDO is also grounded through capacitor C3 to achieve voltage regulation and filtering.

[0069] The lighting control gear indicator module is connected to the secondary control unit. After the secondary control unit receives the gear display control signal sent by the main control unit 102 when it performs lighting control, the secondary control unit controls the display of the lighting control gear information corresponding to the gear display control signal.

[0070] The second switch assembly is connected to the secondary control unit and is used to trigger and output a lighting control signal to the secondary control unit so that the secondary control unit controls the main control unit 102 to perform lighting control according to the preset lighting control logic.

[0083] Among them, see Figure 9 The working indicator module receives control signals sent by the main control MCU through the communication MCU, so that the communication MCU can control the power display module to indicate power information and control the indicator light position display module to indicate the indicator light position information according to the received control signals.

[0084] The charging port of the lamp head includes an ambient light detection circuit, which transmits a first voltage divider signal GK obtained from the charging voltage of the charging port to the main control MCU, so that the main control MCU can determine the ambient light intensity based on the first voltage divider signal GK and control the lighting according to the preset lighting control logic.

[0085] The lamp holder may also include an infrared probe; the infrared probe is connected to the main control MCU to acquire the infrared sensing signal PIR and transmit the infrared sensing signal PIR to the main control MCU, so that the main control MCU can determine the human body sensing information based on the infrared sensing signal PIR and control the lighting according to the preset lighting control logic.

[0086] The lamp head also includes a power detection circuit, which transmits the second voltage divider signal BK obtained from the battery voltage Ba to the main control MCU. The main control MCU then outputs a power display control signal to the communication MCU of the working indicator module based on the second voltage divider signal BK. This allows the communication MCU of the working indicator module to control the power display lamp module to indicate power information based on the power display control signal.
