Description

Technical Field

[0001] This utility model relates to the field of photographic lighting control technology, specifically to an energy-saving control system for photographic lights. Background Technology

[0002] Photography lights often operate at high brightness for extended periods due to a lack of intelligent control logic, maintaining full power output even during non-shooting times (such as lighting adjustments and equipment setup), resulting in significant energy waste. Professional photography lights are mostly in the hundreds of watts range, with ineffective lighting time accounting for over 60% of total operating time, leading to substantial energy loss. Existing equipment lacks energy-saving logic adapted to different scenarios; for example, it cannot automatically reduce the brightness of unnecessary lights based on shooting status (such as the photographer temporarily leaving the camera); when multiple lights work together, it is difficult to individually activate low-power modes for some lights, causing all devices to maintain a uniform energy consumption level and failing to allocate energy as needed. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a photographic light energy-saving control system that can accurately control the energy consumption of multiple lights, dynamically adjust power, and support scenario-based energy-saving modes.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an energy-saving control system for photographic lights, comprising: several light bodies, each light body including a power supply and power supply module, a control and communication module, a light emission and heat dissipation module, an NTC temperature probe, and an automatic step-up / step-down constant voltage and constant current mainboard; the power supply and power supply module includes a battery, a PD3.1 protocol bidirectional fast charging chip, a Type-C female connector, and a DC female connector; the control and communication module includes a first microcontroller with PWM signal output, a first Bluetooth communication module, a first WiFi communication module, a first display screen, and several first encoders; the light emission and heat dissipation module includes a heat sink and a COB light-emitting surface. The automatic step-up / step-down constant voltage / constant current mainboard is connected to the first microcontroller via a ribbon cable and is attached to the outer shell of the lamp body with high-temperature thermally conductive adhesive; the remote control includes a power module, a control communication module, an input module, and an output module. The power module includes a remote control battery. The control communication module includes a second microcontroller, a second Bluetooth communication module, a second WiFi communication module, and a gyroscope. The input module includes several second encoders and switches. The output module includes a second display screen; the first Bluetooth communication module is wirelessly connected to the second Bluetooth communication module, and the first WiFi communication module is wirelessly connected to the second WiFi communication module.

[0005] Preferably, the PD3.1 protocol bidirectional fast charging chip is electrically connected to the Type-C female connector, the DC female connector, and the battery respectively, to realize bidirectional power supply and charging.

[0006] Preferably, the switch is a three-position switch with a first position, a second position, and an off position. When in the first position, the remote control only controls the color temperature and brightness of the light. When in the second position, a power-saving mode is triggered. When the gyroscope detects a preset angle threshold, it sends a signal to the lamp body through the communication module to control the light to turn off or dim. The trigger angle of the power-saving mode supports 3-5 custom settings and 1 default setting. Angle recording and selection can be performed by accessing the secondary menu through one of the second encoders on the remote control.

[0007] Preferably, both the lamp body and the remote control are provided with adjustable channel values, and a seamless connection is achieved when the channel values ​​are consistent; the lamp body is provided with a number value for identification, which is 2-4 digits; the lamp body is provided with a menu page, which supports modifying the channel value and the number value through the first encoder on the lamp body.

[0008] Preferably, the second encoder has three parts, each corresponding to channel selection, color temperature, and brightness adjustment. The first part of the second encoder can be switched to a select all / select a single light mode by long-pressing, and can be locked / unlocked by clicking. When a single or all lights are selected, the corresponding light flashes twice to indicate selection, and the value displayed on the second display screen must remain for 2 seconds before the operation is performed.

[0009] Preferably, the first encoder on the lamp body can be pressed and held to trigger a reverse power supply mode, which supplies power to external devices through the Type-C female connector.

[0010] Preferably, the remote control supports simultaneous connection of no less than 10 of the lamps, and the adjustment operation delay is ≤50ms.

[0011] Preferably, the control motherboard further includes a high-power MOSFET, and the first microcontroller controls the MOSFET through a PWM signal to adjust the power of the COB light-emitting surface.

[0012] Preferably, the remote control supports a long battery life mode. In this mode, one of the second encoders manages the light numbers that trigger the long battery life mode, and the other second encoder manages the light numbers that do not trigger the long battery life mode. After the long battery life mode is triggered, only the brightness of the corresponding light is reduced, without changing its color temperature and light effect parameters.

[0013] With the above structure, this utility model has the following advantages:

[0014] 1. Relying on the remote control's precise selection and adjustment mechanism for single or multiple lights, combined with light flashing feedback and numerical delay execution functions, it avoids energy waste caused by misoperation, solves the redundant energy consumption problem of "one controlling many" in traditional multi-light scenarios, and adjusts parameters only for the target light, greatly reducing unnecessary energy consumption;

[0015] 2. Set power saving mode and long battery life mode. Power saving mode uses the gyroscope to detect the angle and automatically controls the lights to turn off or dim when the photographer leaves or when not working, reducing unnecessary lighting consumption. Long battery life mode can reduce the brightness of a specific light body individually, realizing the on-demand distribution of energy consumption and avoiding all lights from maintaining a uniform high power, significantly extending the battery life of outdoor shooting.

[0024] Combined with appendix Figures 1-3 An energy-saving control system for photographic lights includes several light bodies and a remote controller.

[0025] Each lamp body includes a power supply module 1, a control and communication module 2, a light emission and heat dissipation module 3, an NTC temperature probe 4, and an automatic step-up / step-down constant voltage / constant current mainboard 5. The power supply module 1 includes a battery, a PD3.1 protocol bidirectional fast charging chip, a Type-C female connector, and a DC female connector. The control and communication module 2 includes a first microcontroller with PWM signal output, a first Bluetooth communication module, a first WiFi communication module, a first display screen, and several first encoders. The light emission and heat dissipation module 3 includes a heat sink and a COB light-emitting surface. The automatic step-up / step-down constant voltage / constant current mainboard 5 is connected to the first microcontroller via a ribbon cable and is attached to the lamp body shell with high-temperature thermally conductive adhesive. The remote control includes a power supply module 6, a control and communication module 7, an input module 8, and an output module 9. The power supply module 6 includes a remote control battery. The control and communication module 7 includes a second microcontroller, a second Bluetooth communication module, a second WiFi communication module, and a gyroscope. The input module 8 includes several second encoders and switches. The output module 9 includes a second display screen. The first Bluetooth communication module and the second Bluetooth communication module are wirelessly connected, and the first WiFi communication module and the second WiFi communication module are wirelessly connected.

[0026] In one embodiment of this utility model, the PD3.1 protocol bidirectional fast charging chip is electrically connected to a Type-C female connector, a DC female connector, and a battery, respectively, to achieve bidirectional power supply and charging. Specifically, as shown... Figure 3 As shown, when an external power source is connected via a DC female connector or a Type-C female connector, the PD3.1 protocol bidirectional fast charging chip can automatically identify the input voltage and adjust the charging current to provide a suitable fast charging mode for the battery and improve charging efficiency. At the same time, the chip supplies power to the control and communication module 2 and the light-emitting and heat-dissipating module 3 of the lamp body through the automatic step-up / step-down constant voltage and constant current motherboard 5 to ensure stable power supply. When reverse power supply is required, the first encoder on the lamp body is pressed and held. After receiving the trigger signal, the first microcontroller controls the PD3.1 protocol bidirectional fast charging chip to switch to the discharge mode. At this time, the Type-C female connector can output voltage and current that conform to the PD protocol to power external devices such as laptops and cameras, realizing flexible use of energy.

[0027] In one embodiment of this utility model, the switch is a three-position switch with a first position, a second position, and an off position. When in the first position, the remote control only controls the color temperature and brightness of the light. When in the second position, the power-saving mode is triggered. When the gyroscope detects a preset angle threshold, it sends a signal to the lamp body through the communication module to control the light to turn off or dim. The trigger angle of the power-saving mode supports 3-5 custom settings and 1 default setting. The angle can be recorded and selected by entering the secondary menu through one of the second encoders of the remote control. Specifically, when the three-position switch is switched to the second position, the gyroscope detects the spatial angle changes of the remote control in real time and transmits the angle data to the second microcontroller. The user can access the "Trigger Angle Setting" in the secondary menu through the second encoder and select the default angle or a custom angle. If the custom angle is selected, pressing and holding the third encoder will enter the angle recording state. At this time, the remote control is adjusted to the target angle (such as the angle at which the photographer leaves the camera) and the encoder is clicked to end the recording. This angle will be saved as the trigger threshold. When the angle detected by the gyroscope matches the preset threshold, the second microcontroller sends a control signal to the lamp body through the Bluetooth or WiFi communication module. After receiving the signal, the first microcontroller of the lamp body adjusts the power of the COB light-emitting surface through the PWM signal, so that the light is turned off or reduced to the preset brightness, reducing energy consumption in non-working state.

[0028] In one embodiment of this utility model, both the lamp body and the remote control are equipped with adjustable channel values, enabling seamless connection when the channel values ​​match. The lamp body is equipped with a serial number for identification, which is 2-4 digits. The lamp body also has a menu page that allows modification of the channel value and serial number via a first encoder on the lamp body. Specifically, when the lamp body is first started, it is assigned an initial channel value and serial number by default. The user can access the menu page through the first encoder on the lamp body, rotate the encoder to select the "Channel Setting" or "Serial Number Setting" option, and then press and hold the encoder to confirm to modify the channel value (such as an integer in the range of 0-255) or the serial number (such as a 2-4 digit number). After the remote control is powered on, the second microcontroller will automatically scan for lamps with the same channel value in the vicinity and display the corresponding serial number on the second display screen, achieving seamless connection without manual pairing. Devices with different channel values ​​do not interfere with each other, ensuring accurate control in multi-device scenarios.

[0029] In one embodiment of this utility model, the second encoder has three parts, each corresponding to channel selection, color temperature, and brightness adjustment. The first second encoder can be long-pressed to switch between all / single light selection modes, and a single click locks / unlocks the operation. When a single or all lights are selected, the corresponding light flashes twice to indicate selection, and the value displayed on the second screen remains for 2 seconds before the operation is executed. Specifically, when rotating the first second encoder, the second screen will cycle through the light body numbers in the current channel. After selecting a target number, the corresponding light body will flash twice through its COB emitting surface to indicate selection. Long-pressing the encoder displays "all" on the second screen, and all lights flash twice to indicate entering the all-select mode. A single click on the first second encoder locks the current selection state; at this time, all operations except power on / off are invalid to prevent accidental touches. Another click unlocks the mode. Regardless of whether a single or all light is selected, the values ​​on the second screen (such as brightness and color temperature parameters) remain for 2 seconds until user confirmation before the second microcontroller sends the adjustment signal to the light body, ensuring operational accuracy and reducing unnecessary energy consumption due to misoperation.

[0030] In one embodiment of this utility model, a long press on the first encoder on the lamp body can trigger a reverse power supply mode, supplying power to external devices via a Type-C female connector. Specifically, by pressing and holding both first encoders on the lamp body for 3-5 seconds, the first display screen will show a "reverse power supply" prompt. At this time, clicking on any one of the first encoders confirms the switch, and the first microcontroller controls the PD3.1 protocol bidirectional fast charging chip to switch to output mode. The Type-C female connector begins to output power. During the output process, the first display screen displays the output voltage, current, and remaining power in real time. When the battery power is lower than a preset threshold (e.g., 10%), the system automatically shuts off the reverse power supply, prioritizing the operation of the lamp body itself.

[0031] In one embodiment of this utility model, the remote control supports simultaneous connection to no fewer than 10 lamps, and the adjustment operation delay is ≤50ms. Specifically, the second Bluetooth communication module of the remote control adopts the BLE5.0 protocol, and the first WiFi communication module supports the 802.11n standard. Both have multi-device connection capabilities and can establish stable communication with more than 10 lamps simultaneously. The second microcontroller prioritizes the communication data to ensure that adjustment signals (such as brightness and color temperature commands) are transmitted first. By optimizing the communication protocol stack, the data transmission time is reduced, so that the delay from the remote control sending the command to the lamp executing the operation is controlled within 50ms, ensuring the real-time performance of multi-lamp collaborative adjustment.

[0032] In one embodiment of this invention, the control motherboard further includes a high-power MOSFET. The first microcontroller controls the MOSFET via a PWM signal to adjust the power of the COB light-emitting surface. Specifically, the COB light-emitting surface consists of multiple LED chips with different color temperatures. Each color temperature group corresponds to a high-power MOSFET. After receiving adjustment signals from the remote control and its own encoder, the first microcontroller outputs a PWM signal with a corresponding duty cycle to the gate of the MOSFET, controlling the on and off times of the MOSFET, thereby adjusting the current flowing through the corresponding color temperature LED chip. This achieves continuous adjustment of color temperature and brightness. For example, increasing the PWM duty cycle corresponding to a warm color temperature LED lowers the light color temperature; increasing the current duty cycle of all LEDs increases the overall brightness. Precise power control reduces energy waste.

[0033] In one embodiment of this utility model, the remote control supports a long-battery-life mode. In this mode, one second encoder manages the light numbers that trigger the long-battery-life mode, and another second encoder manages the light numbers that do not trigger the long-battery-life mode. After triggering the long-battery-life mode, only the brightness of the corresponding light is reduced, without changing its color temperature and luminous efficacy parameters. Specifically, after switching to the long-battery-life mode via the second second encoder, the first and third second encoders enter different number management states: rotating the first second encoder allows selection of the light number that needs to trigger the long-battery-life mode, and after clicking confirm, the number is added to the long-battery-life management list; rotating the third second encoder allows selection of the light number that does not need to trigger the long-battery-life mode, and after clicking confirm, it is added to the non-long-battery-life management list. When the long-battery-life mode is activated, the second microcontroller only sends a brightness adjustment signal to the light managed by the first second encoder, and the first microcontroller controls the MOSFET to reduce its power while keeping the color temperature and luminous efficacy parameters unchanged; the light managed by the third second encoder maintains its original parameters, achieving differentiated energy consumption allocation.

[0034] In summary, this utility model achieves precise energy-saving control of photographic lights through the collaborative design of the light body and remote control: on the one hand, it optimizes power supply efficiency through a PD3.1 protocol bidirectional fast charging chip, supporting bidirectional power supply to reduce the amount of equipment carried; on the other hand, it utilizes scenario-based functions such as power-saving mode and long-lasting mode, combined with the precise operation of the gyroscope and encoder, to achieve dynamic adjustment and on-demand allocation of energy consumption for multiple lights, ensuring that the system improves energy-saving effect while taking into account ease of operation and control stability.

In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
