Description

Technical Field

[0001] The invention belongs to the field of photographic equipment and relates to an outdoor energy-saving solar photographic lighting device. Background Art

[0002] With the booming photography industry, outdoor photography, with its unique charm and endless possibilities, is attracting a growing number of photography practitioners and enthusiasts. From magnificent mountain scenery to delicate close-ups of people, from the mysterious microcosm to the grandeur of urban landscapes, outdoor photography encompasses a rich and diverse range of subject matter, providing creators with a vast creative space. However, the unique characteristics of outdoor photography also place higher demands on photographic equipment. Portable, high-performance lighting equipment has become a key factor in meeting these diverse shooting needs.

[0003] At the same time, global energy shortages are becoming increasingly severe, and environmental awareness is growing, driving the rapid development of energy-saving lighting technologies. Among the many clean energy sources, solar energy, with its inexhaustible supply and zero pollution, is increasingly being used in outdoor equipment. This has led to the emergence of outdoor solar lighting equipment, which has gradually become a hot topic in industry research and development. These devices cleverly convert solar energy into electricity to power lighting, while balancing portability and energy efficiency, attracting widespread attention from photographers and outdoor enthusiasts.

[0004] Currently, the outdoor photography lighting market primarily consists of traditional mains-powered or battery-powered photography lights. These traditional devices have numerous limitations. Firstly, they rely heavily on external power sources or require frequent charging, significantly limiting their use in outdoor locations without grid coverage. When shooting in remote mountainous areas, wilderness, or deserts, photographers often struggle to find a suitable power source or need to carry a large number of batteries. This not only increases the weight and bulk of the equipment, reducing portability, but can also affect the progress and quality of the shoot due to insufficient batteries. Secondly, traditional non-solar photography lights consume a lot of energy, which is inconsistent with current energy-saving and environmental trends. As shooting time increases, the power consumption of the equipment also increases, which not only increases operating costs but also places a certain strain on the environment.

[0005] In addition to power supply issues, traditional non-solar photography lights also have significant functional shortcomings. Their lighting adjustment functions are limited, lacking the precise control of color temperature and brightness, as well as the soft light and spotlight modes required for professional photography. In outdoor photography, different scenes and subjects require different lighting effects. For example, when shooting portraits, you may need soft light to create a warm and natural atmosphere; when shooting landscapes, you may need bright, even light to bring out the details and colors of the scene; and when shooting macro shots, you may need spotlight to highlight the subject and blur the background. However, traditional photography lights often fail to meet these diverse needs and are difficult to adapt to the diverse outdoor shooting scenarios, limiting the photographer's creative potential. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide an outdoor energy-saving solar photography lighting device. By optimizing the solar energy conversion and energy storage system, designing an angle-adjustable solar panel, and integrating a professional light effect adjustment module, it can achieve high efficiency and energy saving, stable battery life, and precise and controllable light effect, thereby meeting the diverse needs of outdoor professional photography.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] An outdoor energy-saving solar photography lighting device includes a bracket, a lamp pole, a lamp head, several solar panels and a solar controller; the bracket and the lamp pole are connected by a sliding sleeve, and several legs of the bracket are fixed to the outer side of the sliding sleeve; the lamp head is arranged at the top of the lamp pole; the solar panel is installed in an angle-adjustable manner through a mounting base on the top of the lamp head; the solar controller is electrically connected to the solar panel and the lamp head, and is used to transmit the electrical energy converted by the solar panel to the lamp head.

[0009] Furthermore, the solar panel includes several foldable multi-angle adjustment panels, which are connected to the back of the lamp head through a folding hinge, and the adjustment angle range is 0-180 degrees.

[0010] Furthermore, the solar controller integrates an MPPT maximum power point tracking chip to track the maximum power generation of the solar panel in real time and stabilize the output power voltage and current.

[0011] Furthermore, the solar controller includes a light effect adjustment module with a knob-type color temperature adjustment structure and an adjustment range of 3200K-6500K. The color temperature can be continuously adjusted by controlling the current ratio of the cold / warm light beads in the lamp holder.

[0012] Furthermore, the solar controller also includes an energy storage module, which stores the electrical energy converted from excess solar energy through a rechargeable battery.

[0013] Furthermore, the solar controller is also provided with a protection circuit to protect against overcharging and over-discharging.

[0014] Furthermore, it also includes a mode switching button for switching between three lighting modes: soft light, spotlight, and flash. The mode conversion is achieved by controlling the working status of the LED lamp beads and the position of the spotlight lens.

[0015] Furthermore, the lamp holder includes several high color rendering LED lamp beads, of which cold light beads and warm light beads each account for half, and are connected to the light effect adjustment module through an internal circuit.

[0016] Furthermore, the front end of the lamp head is provided with a detachable soft light cover and a slidable focusing lens. The focusing lens can be adjusted at an angle of 30-60 degrees to achieve switching between soft light and focusing mode.

[0017] Furthermore, the lamp pole is configured as a telescopic pole with an adjustable height range of 50cm-150cm. The lamp head is connected to the lamp pole through a rotating joint, supporting 360-degree horizontal rotation and ±90° pitch adjustment.

[0018] The beneficial effects of the present invention are:

[0019] 1. Solve outdoor power supply limitations and improve energy saving and portability

[0020] Traditional non-solar photography lights have many disadvantages when used outdoors. They are heavily dependent on external power sources, resulting in extremely poor outdoor portability and high energy consumption. The present invention cleverly constructs a solar power supply and energy storage system, successfully breaking through these limitations. Through foldable and multi-angle adjustable solar panels, it can be flexibly adjusted according to the position of the sun, efficiently collect solar energy and convert it into electrical energy, which is then processed by a solar controller and stored in a high-capacity lithium battery. This innovative design allows the device to operate completely independently from the power grid, without the need to carry additional power supplies or frequent charging, greatly improving its flexibility in outdoor scenes. Moreover, as a renewable energy source, solar energy can effectively reduce energy consumption by more than 30% compared to traditional mains electricity or battery power supply. It is in line with the current trend of energy conservation and environmental protection, and provides a sustainable energy solution for outdoor photography.

[0021] 2. Enhance lighting professionalism and adapt to diverse shooting scenes

[0022] Existing solar photography lights are relatively simple in terms of light effect adjustment, and it is difficult to meet the diverse needs of professional photography.

[0029] See also Figure 1 , which is an outdoor energy-saving solar photography lighting device.

[0030] Example 1

[0031] The outdoor energy-saving solar photography lighting device proposed in this embodiment mainly consists of a lamp head, a lamp pole, a bracket and a solar panel, each of which is connected mechanically or electrically to form a unified whole. It also includes the following corresponding components:

[0032] Specifically, the lighting device includes at least a bracket, a lamp pole, a lamp holder, several solar panels and a solar controller, wherein the bracket and the lamp pole are connected by a sliding sleeve, one end of several legs of the bracket is fixed to the outer side of the sliding sleeve, the sliding sleeve is sleeved on the lamp pole, and the lamp holder is arranged at the top of the lamp pole; several solar panels are installed on the top of the lamp holder in an angle-adjustable manner through the mounting seat on the top of the lamp holder; the solar panels and the lamp holder are electrically connected through the solar controller, and the electric energy converted by the solar panels is transmitted to the lamp holder by the solar controller.

[0033] Specifically, this embodiment is equipped with 2-4 foldable, multi-angle adjustable solar panels, each measuring 15cm x 20cm. They are connected to the back of the lamp head via a folding hinge, which allows the solar panels to independently adjust their angles. In actual use, the angle can be flexibly adjusted according to the position of the sun. For example, in the morning or evening when the sun's altitude is low, the angle can be lowered, and at noon when the sun's altitude is high, the angle can be adjusted to near vertical to maximize the reception of sunlight and improve power generation efficiency. The output end of the solar panel is connected to the input end of the solar controller via a wire, which transmits the converted electrical energy.

[0034] The solar panel mount on the top of the lamp uses a hinged mount with an adjustable angle of 0-180 degrees, connecting the solar panel to the back of the lamp. Users can flexibly adjust the solar panel's angle based on the sun's position to maintain optimal light reception and improve charging efficiency. The solar panel can also be independently adjusted to maintain its connection to the lamp.

[0035] In this embodiment, the solar controller integrates an MPPT (Maximum Power Point Tracking) chip, whose input is connected to the solar panel output to receive electrical energy. The MPPT chip tracks the solar panel's maximum power generation in real time, rapidly adjusting the operating point as light intensity fluctuates to maintain maximum power output. Simultaneously, the unstable electrical energy output from the solar panel is stabilized at both the voltage and current levels to meet the charging requirements of the energy storage module. The processed energy is then transmitted through the output to the module's lithium battery.

[0036] In this embodiment, the solar controller also includes a light effect adjustment module, which includes a knob-type color temperature adjustment mechanism. The adjustment range of the knob is 3200K-6500K. The knob is integrated into the side of the lamp body or lamp pole and is connected to the LED lamp beads in the lamp holder through internal circuitry. The user rotates the knob to adjust the current ratio of the cool and warm light beads, achieving continuous color temperature adjustment. For example, turning it clockwise increases the current ratio of the warm light beads, lowering the color temperature, while turning it counterclockwise increases the current ratio of the cool light beads, raising the color temperature.

[0037] The solar controller also includes a mode switch: This switch is integrated into the lamp head or the side of the lamp pole and is connected to the LEDs in the lamp head through internal circuitry. The user presses this button to switch between different lighting modes: soft light mode is suitable for softly illuminating a large area, spot light mode is suitable for highlighting the subject, and strobe light mode can be used to create special effects such as tense and dynamic atmospheres.

[0038] More specifically, the solar controller is also provided with an energy storage module. Specifically, the energy storage module adopts 18650 high-capacity lithium battery, which adopts 2 18650 high-capacity lithium batteries connected in series, with a total capacity of 10000mAh and a voltage of 7.4V. It is connected to the output end of the solar controller, the lamp holder and the light effect adjustment module through wires. When there is sufficient light, the lithium battery is in a charging state, receiving and storing the electric energy transmitted by the solar controller; when there is insufficient light or at night, it automatically switches to a discharge mode to power the lighting module and the light effect adjustment module. Specifically, the solar controller can at least obtain the power consumption information of the lamp holder and the power conversion information of the solar panel, and dynamically adjust the energy transfer route according to the power consumption information of the lamp holder and the power conversion information of the solar panel, wherein, Figure 1 The control logic diagram of the solar controller is shown, which includes:

[0039] If the power consumption of the lamp holder is greater than the amount of solar energy converted, the charging circuit of the energy storage module is turned off, and the discharge circuit of the energy storage module is controlled to open at the same time. The discharge amount is equal to the difference between the power consumption of the lamp holder and the amount of solar energy converted.

[0040] If the power consumption of the lamp holder is equal to the amount of solar energy converted, the charging circuit and the discharging circuit of the energy storage module are turned off, and only the solar panel is used to supply power to the lamp holder;

[0041] If the power consumption of the lamp holder is less than the amount of solar power converted, the charging circuit of the energy storage module is turned on and the discharge circuit of the energy storage module is turned off, and the excess energy from the solar power conversion is transferred to the energy storage module for storage.

[0042] The solar controller also features protection circuits for overcharge and over-discharge. These circuits monitor the lithium battery's status in real time. The overcharge protection circuit prevents excessive voltage during charging, preventing damage and extending battery life. The over-discharge protection circuit automatically shuts off the discharge circuit when the battery level is too low, preventing excessive discharge and protecting battery performance and safety.

[0043] In this embodiment, the lamp base is equipped with several high-color-rendering LEDs. Specifically, in this embodiment, the lamp base includes 36 high-color-rendering LEDs, including 18 cold-light LEDs and 18 warm-light LEDs, with a color rendering index (Ra ≥ 95). These LEDs are fixed inside the lamp base. Internal circuitry connects to a light-effect adjustment module, which adjusts color temperature by controlling the current ratio of the cold / warm-light LEDs and the total LED current to adjust brightness. The combination of cold and warm-light LEDs can meet the needs of different shooting scenarios, such as cold light for technological scenes and warm light for cozy atmospheres.

[0044] The lamp head also features a detachable diffuser, which, along with the lamp housing, protects the lamp beads. The diffuser has a light transmittance of 85% and connects to the front of the lamp head via a snap. Users can choose whether to use it based on their shooting needs. It diffuses light, making it soft and even, reducing shadows and contrast, making it ideal for portraits, still lifes, and other scenes requiring soft lighting.

[0045] The lamp head also features a focusing lens nestled within the diffuser. This lens slides along the lamp head's axis, allowing for a focus angle of 30-60 degrees. Sliding the lens adjusts the focus of the light, switching between soft and spotlight modes. Spotlight mode concentrates the light, making it ideal for macro and close-up shots that emphasize the subject. Softlight mode disperses the light, making it ideal for illuminating large areas.

[0046] In this embodiment, the light pole is retractable, with a height adjustment range of 50cm-150cm. It is connected to the bottom of the lamp holder's connector via a threaded connection. This allows users to flexibly adjust the pole to their desired shooting height, such as retracting the pole for low-angle shots and extending it for higher-up shots. The connection ensures a secure connection between the pole and the lamp body.

[0047] The connection between the lamp head and the lamp pole is set as a rotating joint, which supports 360° horizontal rotation and ±90° pitch adjustment. Users can freely adjust the direction of the lamp head according to shooting angle requirements to achieve all-round lighting coverage, such as horizontal rotation to adjust the lighting direction, pitch adjustment to adjust the light projection angle, while maintaining a stable connection with the lamp stand.

[0048] This embodiment also describes the workflow of the outdoor energy-saving solar photography lighting device of the present invention:

[0049] During the charging phase, the solar panel receives sunlight and converts it into electricity. The MPPT chip tracks the maximum power generated in real time to ensure optimal power output. This energy is then transmitted via wires to the solar controller, where it is stabilized for voltage and current before being stored in the lithium battery. A protection circuit monitors the charging status to prevent overcharging. When sunlight is insufficient, the lithium battery automatically switches to discharge mode to power the lamp.

[0050] Lighting stage: Users adjust color temperature, brightness, and lighting mode through the light effect adjustment module. The knob-type color temperature adjuster adjusts the current ratio of the cool / warm light beads for continuous color temperature adjustment; the touch-sensitive brightness adjuster controls the total LED current for precise brightness adjustment; the mode switch button switches between soft light, spotlight, or strobe modes. The position of the spotlight lens varies depending on the mode, achieving either diffused or concentrated light.

[0051] Adjustable Structure: Users can adjust the device structure according to actual usage. The folding hinge of the solar panel adjusts the angle of the solar panel to be perpendicular to the sunlight to improve charging efficiency. The retractable light frame and the rotating joint of the light head can be rotated and tilted to adapt to different shooting heights and angles.

[0052] Through the above specific implementation methods, the present outdoor energy-saving solar photography lighting device realizes efficient, convenient and energy-saving outdoor photography lighting functions, and provides reliable lighting support for outdoor photography.

[0053] As another preferred embodiment, the solar panel can be replaced with a flexible solar panel to achieve lighter folding and storage without affecting the charging efficiency.

[0054] As another preferred embodiment, the lithium battery of the energy storage module can be replaced with a lithium iron phosphate battery in a scenario where higher capacity is required, thereby increasing the cycle life (but with a slight increase in weight).

[0055] As another preferred embodiment, the color temperature adjustment method of the light effect adjustment module can be achieved by replacing filters with different color temperatures (discontinuous adjustment, lower cost), but the accuracy is lower than electronic adjustment.

[0056] As another preferred embodiment, the connection method between the lamp pole and the lamp holder can be replaced with a quick-release buckle to improve installation efficiency without affecting the function.

[0057] Additionally, the following usage steps are provided:

[0058] 1. Equipment deployment and installation

[0059] Remove the device and place the stand on a stable surface, ensuring the non-slip feet are in full contact with the ground to prevent shaking. Extend the light pole to the desired height (rotate the pole lock clockwise to lock the height, and rotate counterclockwise to unlock). Unfold the solar panel and adjust its angle according to the sun's position (rotate the hinge to position it as perpendicular to the sun as possible) to improve charging efficiency.

[0060] 2. Charging operation

[0061] Solar Charging: In bright sunlight, the solar panel automatically receives sunlight and stores energy for the device through internal circuitry (the charging indicator lights red and turns green when fully charged). Emergency Charging: If sunlight is insufficient, the device can be charged using the USB port on the side of the device (compatible with 5V / 2A chargers). The charging process is synchronized with the status of the solar charging indicator.

[0062] 3. Lighting and light effect adjustment

[0063] Press the power button on the side of the lamp to turn on the lighting (short press to turn on, long press for 3 seconds to turn off).

[0064] Color temperature adjustment: Rotate the "color temperature knob" to continuously adjust between 3200K (warm light) and 6500K (cold light) to suit the lighting requirements of different scenes such as portraits and scenery.

[0065] Brightness adjustment: Press the "Brightness +" and "Brightness -" keys to achieve precise control of 0-100% brightness to meet the light intensity requirements of different environments.

[0066] Mode switch: Press the "Mode button" to switch between soft light (soft and diffuse light), spotlight (concentrated light), and strobe (high-frequency flashing) modes. Sliding the spotlight lens at the front of the lamp head can help enhance the soft light / spot light effect.

[0067] 4. Angle adjustment

[0068] The lamp head features a swivel joint that allows for ±90° pitch adjustment and 360° horizontal rotation, allowing for precise alignment of the subject. To adjust the solar panel angle during filming (e.g., to adjust the sun's position), simply rotate the folding hinge without shutting down the device.

[0069] 5. Storage and maintenance

[0070] After use, turn off the power, retract the light pole to its shortest position, fold the solar panel to fit the light body, and fold the bracket to store it. Regularly wipe the solar panel surface with a dry cloth to prevent dust from obstructing charging efficiency. Avoid getting water in the light head; if it gets wet, wipe it dry before use.

[0071] In response to the problems that traditional photography lights rely on external power supplies, have poor outdoor portability and high energy consumption, the present invention adopts a solar power supply system to achieve independent operation off the power grid, improve portability for outdoor use, and at the same time reduce energy consumption, meeting energy-saving needs; in response to the problem that existing products have a single light effect adjustment function and cannot adapt to a variety of professional photography scenes, the present invention integrates a professional light effect adjustment module to achieve precise control of color temperature and brightness and switching of modes such as soft light and focusing to adapt to the lighting requirements of different outdoor shooting scenes such as portraits, scenery, and macro; in summary, the present invention provides an outdoor energy-saving solar photography light, which, through the above improvements, achieves high efficiency and energy saving, stable battery life, precise and controllable light effect, and adaptability to outdoor professional photography scenes.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
