Description

Technical Field

[0001] This application relates to the technical field of lighting fixtures, and more particularly to a lighting fixture. Background Technology

[0002] In the field of modern lighting, lamps are increasingly diversified in design and function to meet different occasions and aesthetic needs, such as solar ground lights, solar wall lights, solar floodlights, and solar lawn lights.

[0003] Currently, commercially available solar lawn lights typically consist of a light-transmitting cover, solar-powered light bulbs, a battery pack, and a ground socket. However, most existing solar lawn lights are single-color, offering limited color options and failing to meet diverse usage scenarios and user preferences. To address this, a few color-changing solar lawn lights have been introduced, but their color-changing function involves adding a switch button to the solar panel and creating openings on the panel to accommodate the switch. This design not only significantly increases the manufacturing cost of the solar panel but also easily reduces its performance, affecting its stability.

[0004] In view of this, the applicant has developed and designed a solar lawn light fixture that eliminates the need for an actual switching button. The main structure includes a light-transmitting cover, a light-emitting lamp group with storage and control circuits, a battery pack, a conductive plate, and connecting conductive wires. By rotating the battery pack clockwise and counterclockwise, the connection between the battery pack and the conductive plate is controlled, thereby achieving the light color switching function of the existing actual switching button, thus eliminating the technical problems existing in the current structure of adding a switching button to the solar panel.

[0005] However, during the research and development process, the applicant encountered a problem where the battery pack easily made multiple brief contacts with the conductive plate when rotating, resulting in unstable light color switching and thus affecting the user experience. To solve this problem, the applicant has developed a new type of solar lawn light to meet practical usage needs. Utility Model Content

[0072] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0073] Example 1:

[0074] like Figures 1 to 11 As shown, a lighting fixture includes a light-transmitting lampshade 100 having a accommodating cavity 101, a light-emitting lamp group 200 disposed on the accommodating cavity 101, a connecting wire group 300 connected to the lower side of the light-emitting lamp group 200, and also includes a conductive plate 400 and a locking connector 500.

[0075] The conductive plate 400 is disposed on the lower side of the connecting wire group 300, and a positive conductive area 401 and a pre-tightening connection area 402 located outside the positive conductive area 401 are provided in the middle of its lower side, as well as a negative conductive area 403 concentrically disposed with the pre-tightening connection area 402.

[0076] The battery pack 500 is rotatably connected to the lower side of the light-transmitting lamp cover 100, and its positive terminal is connected to the positive conductive area 401, while its negative terminal can be switched between the pre-tightening connection area 402 and the negative conductive area 403.

[0077] This lamp utilizes a combination of a light-transmitting lampshade 100, a light-emitting lamp group 200, a connecting wire group 300, a conductive plate 400, and a battery pack 500. The conductive plate 400 is equipped with a positive conductive area 401, a pre-tightening connection area 402, and a negative conductive area 403. When the battery pack 500 is connected to the conductive plate 400, the positive terminal of the battery pack 500 connects to the positive conductive area 401, while the negative terminal first contacts the pre-tightening connection area 402. Then, the battery pack 500 is rotated to transfer the negative terminal from the pre-tightening connection area 402 to the negative conductive area 403, ensuring a stable connection. This effectively avoids the problem of disordered light color switching caused by multiple brief contacts between the battery pack 500 and the conductive plate 400, ensuring the accuracy and stability of the lamp's light color switching and improving the user experience.

[0078] Furthermore, a gap 404 is provided between the pre-tightening connection area 402 and the negative electrode conductive area 403. This is to effectively separate the pre-tightening connection area 402 and the negative electrode conductive area 403.

[0079] Furthermore, the material used to make the light-transmitting lampshade 100 can be acrylic with high light transmittance or glass with high light transmittance, preferably glass with high light transmittance, to ensure uniform brightness when the lamp is lit and improve the quality of light effect.

[0080] The lamp also includes a conductive plate connector 600 and a locking connector 700.

[0081] The conductive plate connector 600 is located on the lower side of the light-transmitting lamp cover 100 and extends upward into the accommodating cavity 101. It has an accommodating cavity 601 for accommodating the conductive plate 400, and also has a communicating cavity 602 located on the upper side of the accommodating cavity 601 and communicating with the accommodating cavity 601.

[0082] The locking connector 700 is threaded to the outer side of the upper end of the conductive plate connector 600, and its lower side is pressed against the bottom surface of the accommodating cavity 101 for locking the conductive plate connector 600, and a clearance opening 701 communicating with the communicating cavity 602 is provided thereon.

[0083] The lower end of the connecting wire group 300 passes through the clearance opening 701 and the communicating cavity 602 in sequence and then connects to the conductive plate 400.

[0084] This application, through the ingenious design of the conductive plate connector 600 and the locking connector 700, ensures the stable installation of the conductive plate 400 and reduces the molding difficulty of the light-transmitting lampshade 100, thereby facilitating production and assembly.

[0085] Furthermore, the lamp also includes a ground socket 800 detachably connected to the lower side of the battery pack 500, which is intended to facilitate the user to insert the lamp into the lawn.

[0086] Furthermore, the connecting wire assembly 300 includes a positive wire 301 and a negative wire 302, both of which are silver wires or silver-plated wires; preferably, they are silver wires to ensure excellent conductivity and corrosion resistance, improve circuit stability, and extend the lifespan of the lamp. Simultaneously, the high conductivity of silver wires helps reduce resistance, decrease energy loss, and improve luminous efficiency, further enhancing the overall performance of the lamp.

[0087] The lower left sidewall of the communicating cavity 602 is provided with a left protrusion 6021 that protrudes to the right, and the lower right sidewall is provided with a right protrusion 6022 that protrudes to the left.

[0088] The left protrusion 6021 has a left limiting opening 60211 for limiting the lower end of the positive conductor 301. The purpose is to effectively limit the positive conductor 301, prevent it from shifting, and ensure stable circuit connection.

[0089] The right protrusion 6022 has a right limiting opening 60221 for limiting the lower end of the negative conductor 302. The purpose is to effectively limit the negative conductor 302, prevent it from shifting, and ensure stable circuit connection.

[0090] Furthermore, the cavity 601 is provided with an internal thread 6011;

[0091] The battery pack 500 includes a connecting housing 51, a battery 52, and a conductive spring 53;

[0092] The upper outer side of the connecting housing 51 is provided with an external thread 511 that can be connected to the internal thread 6011, and a placement cavity 512 is also provided thereon.

[0093] The battery 52 is disposed in the placement cavity 512, and its upper positive terminal is connected to the positive electrode conductive area 401.

[0094] The conductive spring 53 is disposed in the placement cavity 512, with its lower end located below the battery 52 and its upper end extending upward to hook onto the upper side wall of the connecting housing 51 for connection with the pre-tightening connection area 402 or the negative electrode conductive area 403.

[0095] When the battery pack 500 is connected to the conductive plate connector 600, the conductive spring 53 is compressed by the battery 52, and the battery 52 is also reacted by the elastic force of the conductive spring 53, so that the entire battery pack 500 has a certain pre-tightening force when initially connected to the conductive plate connector 600. This facilitates close contact between the upper positive terminal of the battery 52 and the positive conductive area 401, and also facilitates close contact between the upper end of the conductive spring 53 and the pre-tightening connection area 402 or the negative conductive area 403. This design ensures that the battery pack 500 can be stably connected to the conductive plate 400.

[0096] Furthermore, the exterior of the light-transmitting lampshade 100 is provided with a refractive part 102 that can refract light to present a light spot pattern, in order to enhance the visual effect of the entire lamp and thus improve its artistry and aesthetics.

[0097] Furthermore, the light-emitting lamp assembly 200 includes a solar panel 21, an intermediate adjustment housing 22, a PCB board 23, and lamp beads 24; the solar panel 21 is disposed on the upper side of the accommodating cavity 101; the intermediate adjustment housing 22 is disposed on the lower side of the solar panel 21, and has a through cavity 221 extending vertically through it; the PCB board 23 is disposed on the lower side inside the through cavity 221, and is connected to the solar panel 21 and the connecting wire assembly 300; the lamp beads 24 are disposed on the lower side of the PCB board 23, and are used to emit light when powered.

[0098] The reason for adopting the design of the intermediate adjustment housing 22 in this application is as follows:

[0099] During the design and development process, the different heights of the LED beads 24 located inside the accommodating cavity 101 result in different light-emitting effects and significantly affect the light spot pattern after refraction by the refractive part 102.

[0100] Therefore, this application designs a replaceable intermediate adjustment housing 22 to flexibly adjust the position of the LED beads 24, avoiding blurring or shifting of the light spot, so as to ensure the aesthetics and visual appeal of the light spot pattern.

[0101] Furthermore, the lower left side of the through cavity 221 is provided with a lower left limiting slot 2211 for limiting the upper end of the positive electrode wire 301, and the lower right side is provided with a lower right limiting slot 2212 for limiting the upper end of the negative electrode wire 302, in order to ensure that the wire is stable and does not deviate.

[0102] Furthermore, refer to Figure 2 and Figure 12 As shown, there are multiple LED beads 24, and the multiple LED beads 24 emit light of different colors after being powered on;

[0103] The PCB board 23 is provided with a control circuit 231, a light detection circuit 232, a storage circuit 233, a unidirectional conductive circuit 234, a battery management circuit 235, a delay circuit 236, and a clamping circuit 237.

[0104] The input terminal of the control circuit 231 is connected to the output terminal of the light detection circuit 232. The bidirectional data terminal of the control circuit 231 is connected to the bidirectional data terminal of the storage circuit 233. The output terminal of the control circuit 231 is connected to the negative terminals of the plurality of lamp beads 24 respectively to control at least one of the plurality of lamp beads 24 to emit light. The power input terminal of the control circuit 231 is connected in parallel with the delay circuit 236. The power input terminal of the control circuit 231 is connected in parallel with the clamping circuit 237. The power input terminal of the control circuit 231 is connected to the output terminal of the unidirectional conductive circuit 234. The input terminal of the unidirectional conductive circuit 234 is connected to the output terminal of the solar panel 21. The output terminal of the unidirectional conductive circuit 234 is connected to the input terminal of the battery management circuit 235. The output terminal of the battery management circuit 235 is electrically connected to the battery 52.

[0105] The control circuit 231 can be implemented using a microprocessor, microcontroller, or programmable logic device, controlling the light-emitting state of multiple LED beads 24 through a preset program to achieve different color lighting effects. The light detection circuit 232 detects the ambient light intensity and sends the detected light intensity signal to the control circuit 231. In this embodiment, the presence or absence of light can be determined by whether the solar panel 24 generates electricity. The storage circuit 233 stores information such as the lamp's operating parameters and lighting effect settings, which can be retrieved by the control circuit 231 when needed. The unidirectional conductive circuit 234 acts as a rectifier, ensuring that the DC power output from the solar panel 21 can be correctly connected to the circuit. The battery management circuit 235 manages the charging and discharging process of the battery 52, protecting it from damage such as overcharging and over-discharging. The delay circuit 236 is used to maintain the current light color when the power outage time is less than 0.5 seconds. When there is sufficient sunlight, the electrical energy generated by the solar panel 21 charges the battery 52 through the unidirectional conductive circuit 234 and the battery management circuit 235, and the excess electrical energy is also stored in the delay circuit 236. When there is insufficient sunlight or when lighting is needed, the control circuit 231 draws electrical energy from the battery 52 to control multiple LED beads 24 to emit light. The clamping circuit 237 is used to limit the voltage or current in the circuit to protect other components in the circuit from damage.

[0106] The control circuit 231 can automatically adjust the brightness and color of multiple LED beads 24 according to the ambient light intensity or preset time conditions to provide a suitable lighting effect. For example, in daylight or well-lit environments, the control circuit 231 can control the LED beads 24 to emit light at a lower brightness, or even turn off some or all of the LED beads 24 to save energy; while at night or in dimly lit environments, the control circuit 231 can control the LED beads 24 to emit light at a higher brightness and adjust the emission color as needed to create different atmospheres. In addition, users can also send commands to the control circuit 231 through an external operating interface (such as a remote control or a smartphone application) to manually adjust the lighting effects to meet personalized lighting needs.

[0107] The storage circuit 233 can store information such as the usage history and fault records of the lamps, so as to facilitate troubleshooting and maintenance.

[0108] The battery management circuit 235 monitors the state of charge of the battery 52 and manages and optimizes the electrical energy output from the solar panel 24 via the unidirectional conductive circuit 234, ensuring the lifespan and performance of the battery 52. ​​For example, when the battery 52 is fully charged, the battery management circuit 235 can control the battery 52 to discharge at a lower rate to extend its usage time. Furthermore, the battery management circuit 235 can automatically turn off the light fixture or reduce the brightness when the battery 52 is too low to prevent damage from over-discharge. This intelligent battery management strategy not only improves the energy efficiency of the light fixture but also provides users with a more reliable and longer-lasting lighting experience.

[0109] The control circuit 231, light detection circuit 232, storage circuit 233, unidirectional conductive circuit 234, battery management circuit 235, delay circuit 236, and clamping circuit 237 of this embodiment can achieve stable and reliable switching of light color modes. The switching process is as follows:

[0110] When the connecting housing 51 containing the battery 52 is loosened by rotating counterclockwise, and the counterclockwise rotation angle is ≥90 degrees, the power is cut off and the light goes out.

[0111] When the power outage time is ≥0.5 seconds, and the connecting housing 51 is rotated clockwise again until it is tightened, the lamp will cycle through and switch to the next light color.

[0112] When the power outage time is less than 0.5 seconds, the current light color can be maintained within the power outage time of less than 0.5 seconds by combining the program design in the control circuit 231, the memory function of the storage circuit 233, and the delay circuit 236 implemented by the capacitor.

[0113] Furthermore, refer to Figure 13 and based on the above Figure 12 In the embodiment shown, the control circuit 231 includes a control chip U1;

[0114] The storage circuit 233 includes a storage chip U3, and the bidirectional data terminal of the storage chip U3 is connected to the bidirectional data terminal of the control chip U1.

[0115] The light detection circuit 232 includes a first resistor R9 and a second resistor R10 connected in series. The common node of the first resistor R9 and the second resistor R10 is connected to the input terminal of the control chip U1. The first end of the first resistor R9 is connected to the negative terminal of the solar panel 21, and the second end of the second resistor R10 is connected to the positive terminal of the solar panel 21.

[0116] The delay circuit 236 includes a first capacitor C1 and a second capacitor C2. The first capacitor C1 is connected in parallel with the power input terminal of the control chip U1, and the second capacitor C2 is connected in parallel with the power input terminal of the control chip U1.

[0117] The clamping circuit 237 includes a first diode Z1, the two ends of which are connected in parallel with the power input terminal of the control chip U1.

[0118] The unidirectional conductive circuit 234 includes a second diode D1, the positive terminal of the second diode D1 is connected to the positive terminal of the solar panel 21, a third resistor R13 is connected in series between the negative terminal of the second diode D1 and the power input terminal of the control chip U1, and the negative terminal of the second diode D1 is connected to the positive terminal of the battery 52.

[0119] The battery management circuit 235 includes a power chip U2, a fourth resistor R2, and a third capacitor C3. The first end of the fourth resistor R2 is connected to the negative terminal of the second diode D1, the first end of the fourth resistor R2 is connected to the positive terminal of the battery 52, the second end of the fourth resistor R2 is connected to the first end of the third capacitor C3, the second end of the third capacitor C3 is grounded, and the common node of the fourth resistor R2 and the third capacitor C3 is electrically connected to the power chip U2.

[0120] The control chip U1 serves as the core component of the control circuit 231, responsible for receiving the light intensity signal sent by the light detection circuit 232 and controlling the illumination state of multiple LED beads 24 according to a preset program or user instructions. The storage chip U3 stores various operating parameters and user settings of the lamp, ensuring the lamp operates as expected. Data transmission between the storage chip U3 and the control chip U1 can be achieved via the I²C protocol. The voltage divider circuit composed of the first resistor R9 and the second resistor R10 reduces the voltage generated by the solar panel 21 to a level suitable for the control chip U1 to process, thereby achieving accurate detection of ambient light intensity. The first capacitor C1 and the second capacitor C2, acting as energy storage capacitors, not only filter the electrical energy output from the solar panel or battery but also provide temporary power support to the control chip U1 when it is powered off, ensuring a smooth transition to the power-off state and preventing damage to the control chip U1 from sudden power outages. The first diode Z1 acts as a clamping diode, clamping the voltage at the power input terminal of the control chip U1 within a safe range to prevent damage to the control chip U1 or other circuit components due to excessive voltage. The second diode D1 acts as a rectifier diode, allowing only unidirectional flow of DC power generated by the solar panel 21, ensuring that electrical energy is correctly connected to the circuit while preventing backflow that could damage the solar panel 21. The third resistor R13 acts as a current-limiting resistor, limiting the current flowing through the second diode D1 and protecting it from excessive current surges. The power chip U2, as the core component of the battery management circuit 235, is responsible for monitoring the state of charge of the battery 52 and controlling the charging and discharging process based on the battery's charge level, ensuring the battery's lifespan and performance. The filter circuit composed of the fourth resistor R2 and the third capacitor C3 filters the input voltage of the power chip U2, removing high-frequency noise and ripple to ensure stable operation of the power chip U2.

[0121] This type of lighting fixture not only has intelligent lighting control functions, which can automatically adjust the lighting effect according to the ambient light intensity or user instructions, but also has a complete circuit protection mechanism, which can ensure that the fixture can operate stably in various environments, providing users with a more reliable and lasting lighting experience.

[0122] Example 2:

[0123] Please refer to Figures 1 to 8 ,as well as Figures 10 to 14 As shown, the difference between this embodiment and Embodiment 1 is that:

[0124] This embodiment provides a lamp fixture, including a light-transmitting lampshade 100 having a accommodating cavity 101, a light-emitting lamp group 200 disposed on the accommodating cavity 101, and a connecting wire group 300 connected to the lower side of the light-emitting lamp group 200. The lamp fixture further includes:

[0125] A conductive plate 400 is disposed on the lower side of the connecting wire group 300, and a positive conductive area 401a and a negative conductive area 403a located outside the positive conductive area 401a are provided in the middle of its lower side.

[0126] The battery pack 500 is rotatably connected to the lower side of the light-transmitting lamp cover 100, and its positive terminal is connected to the positive conductive area 401a, and its negative terminal is connected to the negative conductive area 403a in an open-closed manner.

[0127] The light-emitting lamp group 200 includes lamp beads 24 and PCB board 23. Multiple lamp beads 24 are provided, and multiple lamp beads 24 emit light of different colors after being powered on.

[0128] The PCB board 23 is provided with a control circuit 231, a light detection circuit 232, a storage circuit 233, and a delay circuit 236;

[0129] The input terminal of the control circuit 231 is connected to the output terminal of the light detection circuit 232. The bidirectional data terminal of the control circuit 231 is connected to the bidirectional data terminal of the storage circuit 233. The output terminal of the control circuit 231 is connected to the negative terminals of the plurality of lamp beads 24 respectively, so as to control at least one of the plurality of lamp beads 24 to emit light. The power input terminal of the control circuit 231 is connected in parallel with the delay circuit 236.

[0130] In this embodiment, the accommodating cavity 101 is a space for installing and accommodating the light-emitting lamp assembly 200 and other electronic components. Its shape and size can be designed according to actual needs. The light-transmitting lampshade 100 can be made of a material with good light transmission properties, such as glass or plastic, to ensure that the light can evenly illuminate the surrounding environment. The light-emitting lamp assembly 200 includes multiple LED beads 24 and a PCB board 23. The LED beads 24 can emit different colors of light after being powered on, providing users with a variety of lighting effects. The PCB board 23 integrates electronic components such as a control circuit 231, a light detection circuit 232, a storage circuit 233, and a delay circuit 236, realizing intelligent control of the lamp. Among them, the control circuit 231, as the core component, is responsible for receiving the light intensity signal sent by the light detection circuit 232 and controlling the light emission state of multiple LED beads 24 according to a preset program or user instructions. The storage circuit 233 is used to store information such as the lamp's operating parameters and lighting effect settings, so that it can be read by the control circuit 231 when needed. The delay circuit 236 is used to ensure that the circuit retains its current light color when the power-off time is less than 0.5 seconds.

[0131] The control circuit 231 can automatically adjust the brightness and color of multiple LED beads 24 according to the ambient light intensity or preset time conditions to provide a suitable lighting effect. For example, in daylight or well-lit environments, the control circuit 231 can control the LED beads 24 to emit light at a lower brightness, or even turn off some or all of the LED beads 24 to save energy; while at night or in dimly lit environments, the control circuit 231 can control the LED beads 24 to emit light at a higher brightness and adjust the emission color as needed to create different atmospheres. In addition, users can also send commands to the control circuit 231 through an external operating interface (such as a remote control or a smartphone application) to manually adjust the lighting effects to meet personalized lighting needs.

[0132] A conductive plate 400 is located below the connecting wire assembly 300 and is used to transfer electrical energy provided by the battery pack 500 to the light-emitting lamp assembly 200. The positive conductive area 401a and negative conductive area 403a on the plate are connected to the positive and negative terminals of the battery pack 500, respectively, to control the circuit. The battery pack 500, as the power supply for the lamp, is connected to the lower side of the light-transmitting lampshade 100 via a rotating connection, facilitating user replacement or charging. Its positive terminal is connected to the positive conductive area 401a, and its negative terminal is connected to the negative conductive area 403a via a method such as a spring contact or metal sheet to achieve on / off connection.

[0133] In Embodiment 2 of this application, through the power connection structure between the battery pack 500 and the conductive plate 400, and the coordinated operation of the control circuit 231, light detection circuit 232, storage circuit 233, and delay circuit 236 on the composite PCB board 23, the problem of disordered light color switching sequence caused by multiple brief contacts between the battery pack 500 and the conductive plate 400 can be effectively avoided, which is close to the problem described in Embodiment 1. At the same time, during the assembly and production process, it is also possible to eliminate the need to check the specific placement of the partition positions on the conductive plate 400, thereby improving production efficiency.

[0134] The above description is one implementation method provided in conjunction with specific content, and does not imply that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to or identical to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
