Description

Technical Field

[0001] The utility model relates to the field of lamps, in particular to a garden lamp with adjustable lighting modes. Background Art

[0002] With the development of urbanization and the improvement of people's living standards, outdoor lighting equipment, especially garden lights and lawn lights, are becoming more and more widely used. These lighting devices can not only provide basic lighting functions, but also beautify the environment and create an atmosphere by illuminating plants with light.

[0003] For example, patent publication number CN213810342U, entitled "An Angle-Adjustable Lawn Lamp," specifically discloses an angle-adjustable lawn lamp comprising a lamp post and a lamp barrel fixed to the top of the lamp post. The lamp barrel can be cylindrical in shape, with an internal cavity for accommodating objects. A power module is located within the cavity, comprising a power supply and associated protection circuitry for providing electrical energy. The outer side of the lamp barrel has an inwardly recessed groove that is not connected to the cavity. A fixing surface is located at the top of the groove, which is tilted relative to the axis of the lamp post so that the light is primarily directed obliquely downward, illuminating the ground. The fixing surface has an opening connected to the cavity. An outer ring body is fixed within the opening. An inner ring body is located within the inner side of the outer ring body, and the inner ring body can be arranged concentrically with the outer ring body. Two radially outwardly extending rotating rods are located on the outer wall of the inner ring body. The two rotating rods are coaxially arranged so that the two rotating rods are located on the same diameter of the inner ring body. Two rotating holes that are compatible with the rotating rods are provided on the side wall of the outer ring body. The positions and sizes of the rotating holes correspond to the positions and sizes of the rotating rods respectively. The two rotating rods are respectively inserted into the two rotating holes and can rotate in the rotating holes. A lighting module is fixed on the inside of the inner ring body. The lighting module is electrically connected to the power module. The power module supplies power to the lighting module so that the lighting module emits light to provide lighting. When using the lawn lamp of this embodiment, the angle between the axial direction of the inner ring body and the axial direction of the lamp tube can be adjusted. The larger the angle, the longer the illumination distance of the lighting module and the wider the illumination range. Conversely, the closer the illumination distance of the lighting module and the smaller the illumination range, thereby achieving the effect of changing the lighting atmosphere and improving the applicability of the product.

[0004] As described above, the lawn lamp disclosed in the prior art only provides a single lighting mode. By adjusting the relative position of the lamp tube and the lamp pole, the illumination distance and illumination range of the lamp tube can be changed. However, the illumination range is still limited to the light outlet groove provided on the lamp pole. In fact, the adjustment is made within a fixed illumination range. The illumination range is single and cannot be adjusted at multiple angles. The small adjustment range limits users' use in different scenarios. In addition, the lighting effect is single, that is, it uses a single light source, which cannot provide the requirements of multiple lighting effects and cannot meet the needs of different lighting scenarios, which is not conducive to energy conservation.

[0027] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0028] like Figures 1 to 6As shown, this case provides a garden light with adjustable lighting modes, specifically including a lamp tube 1 and a light source module 2 rotatably connected to the lamp tube 1. The lamp tube 1 is the main part of the entire garden light. When implemented, it is cylindrical, and a power module and other corresponding components are provided inside it. The light source module 2 provides a light source to achieve a variety of lighting modes. The garden light in this case also includes a conical connector 3, the upper end of the conical connector 3 is circumferentially concave inward to form a conical portion 31 that is narrow at the top and wide at the bottom. The upper end of the conical connector 3 is fixedly connected to the light source module 2 through the conical portion 31, and the lower end of the conical connector 3 is rotatably connected to the lamp tube 1. Through the rotatable connection between the conical connector 3 and the lamp tube 1, the user can adjust the relative position of the conical connector 3 and the lamp tube 1 to achieve adjustment of the light source module 2, increase the adjustment range of the lighting angle, and achieve lighting in different directions and ranges. An annular light-emitting portion 100 is formed between the light source module 2 and the tapered portion 31. The annular light-emitting portion 100 directs light downward and outward from the annular light-emitting portion 100, ensuring that the light can be evenly distributed, providing a wider lighting range, enhancing the lighting effect, avoiding the problem of uneven lighting caused by a single light outlet, improving the lighting effect, and providing a wider range of application scenarios. The light source module 2 includes a circuit board 21. The circuit board 21 is downwardly provided with a first LED lamp bead 211 and a second LED lamp bead 212 that can emit light from the annular light-emitting portion 100, and the first LED lamp bead 211 and the second LED lamp bead 212 have different light angles along the annular light-emitting portion 100. By integrating the first LED lamp bead 211 and the second LED lamp bead 212 on the circuit board 21, a variety of lighting modes and multiple lighting angles are achieved, meeting the lighting needs of more different scenarios and providing more flexible and diverse lighting effects. In specific implementation, users can also integrate a combination of three or more LED lamp beads to meet actual needs. The circuit board 21 can independently control the operation of the first LED lamp bead 211 and the second LED lamp bead 212. Users can independently control the operation of the first LED lamp bead 211 and the second LED lamp bead 212 through the circuit board 21. According to different lighting needs, the user can choose to turn on the first LED lamp bead 211 and turn off the second LED lamp bead 212, or turn on the second LED lamp bead 212 and turn off the first LED lamp bead 211, thereby providing different lighting modes. Compared with the single light source in the existing technology, this is more flexible and helps save energy.

[0029] Specifically, refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5As shown, two groups of first LED beads 211 are arranged along the periphery of the circuit board 21 in this embodiment, with each group comprising a number of equally spaced first LED beads 211. In practice, the light source module 2 is cylindrical in shape, and the circuit board 2 is configured in a circular ring shape. The two groups of first LED beads 211 are evenly distributed around the periphery of the circuit board 21. The first LED beads 211, along the annular light-emitting portion 100, emit a 360° illumination angle, making them suitable for scenarios requiring all-around illumination, such as illuminating an entire courtyard or lawn, ensuring complete illumination.

[0030] Continue to refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 As shown, specifically, two parallel groups of second LED lamp beads 212 are provided, each group comprising a plurality of second LED lamp beads 212. The second LED lamp beads 212 are disposed at the left or right end of the inner side of the circuit board 21. In a specific implementation, the first LED lamp beads 211 are disposed outside the second LED lamp beads 212. The second LED lamp beads 212 are suitable for localized diffuse lighting. Combined with the all-around lighting provided by the first LED lamp beads 211, different lighting effects can be achieved in different scenarios.

[0031] Reference Figure 1-Figure 5 As shown, further, the light source module 2 in this case also includes a connecting seat 22 installed on the upper end of the circuit board 21. A mounting cavity 200 is provided at the lower end of the connecting seat 22, and the circuit board 21 is embedded in the mounting cavity 200 and is fixedly connected to the connecting seat 22. The setting of the mounting cavity 200 provides an installation space for the circuit board 21, which is beneficial to saving the internal space of the light source module 2 and effectively simplifies the installation process. The connecting seat 22 ensures the stability and reliability of the circuit board 21 and prevents loosening due to vibration or external factors. A shading structure is provided in the mounting cavity 200 for limiting the illumination angle of the second LED lamp bead 212 along the annular light output portion 100. By providing a shading structure, the illumination angle of the second LED lamp bead can be controlled, ensuring that the illumination angle of the second LED lamp bead 212 is within a predetermined range, thereby improving the accuracy and effect of the lighting.

[0032] Specifically, if Figure 1-Figure 5As shown, the light-shielding structure includes a fixing base 221 for connecting and fixing the circuit board 21. In a specific implementation, the fixing base 221 and the connecting base 22 are integrally formed, and the circuit board 21 is connected and fixed to the connecting base 22 via the fixing base 221. The fixing base 221 includes a first baffle 2211 and a second baffle 2212. The first baffle 2211 and the second baffle 2212, together with the sidewalls of the fixing base 221, form a light-shielding area 300. The second LED lamp bead 212 is disposed in the light-shielding area 300, thereby limiting the illumination angle of the second LED lamp bead 212. The light-shielding area 300 limits the illumination angle of the second LED lamp bead 212 along the annular light-emitting portion 100 to 120°-180°. In a specific implementation, the user can adjust the relative positions of the first baffle 2211 and the second baffle 2212 as needed, thereby changing the shape of the light-shielding area 300 to adjust the illumination angle of the second LED lamp bead 212 within a range of 120°-180°. Specifically, the first baffle 2211 and the second baffle 2212 can be configured as an adjustable structure. Preferably, in this case, the illumination angle of the second LED lamp bead 212 along the annular light outlet portion 100 is limited to 180°.

[0033] Further, if Figure 1 、 Figure 4 、 Figure 5 As shown, the lower end of the conical connector 3 is covered on the outer wall of the upper end of the lamp tube 1. The upper end of the lamp tube 1 is concavely formed with an annular groove 11. The lower end of the conical connector 3 is provided with a bolt 32. The front end of the bolt 32 is inserted into and pressed into the annular groove 11 to fix the conical connector 3 relative to the lamp tube 1. In specific implementation, a screw hole for the bolt 32 is provided at the lower end of the conical connector 3. When the garden light in this case has been installed, if the illumination range, direction, or light output angle of the second LED lamp bead 212 does not meet the user's needs, if the user needs to adjust the illumination range, direction, or light output angle of the second LED lamp bead, they only need to loosen the bolt 32, thereby rotating the conical connector 3 relative to the lamp tube 1 until it is adjusted to the desired position, and then tighten the bolt 32. This method is easy to adjust and is conducive to further providing different illumination directions and angles. The cooperation between the bolt 32 and the annular groove 11 provides a flexible adjustment function, allowing users to adjust the lighting direction and angle as needed, and is applicable to a wider range of scenarios.

[0034] Continue to refer to Figure 1 、 Figure 4 、 Figure 5As shown, the bottom of the lamp tube 1 is provided with a first switch 12, exposed on the bottom wall of the lamp tube 1, for turning the first LED lamp bead 211 and the second LED lamp bead 212 on and off. A second switch 13 is also provided at the bottom of the lamp tube 1 for adjusting the color temperature of the first LED lamp bead 211 and the second LED lamp bead 212. Both the first switch 12 and the second switch 13 are electrically connected to the circuit board 21. The first and second switches 12, 13 are both exposed on the bottom wall of the lamp tube 1, allowing the user to easily turn the first and second LED lamp bead 211 and 212 on and adjust their color temperature directly from outside the lamp tube 1. In practice, the garden light in this embodiment can achieve two color temperature effects: warm white and cool white, but is not limited to these two. Users can adjust the current control or pulse width modulation mode of the corresponding circuit board 21 to achieve a variety of color temperature effects as needed. The second switch 13 provides users with a variety of color temperature options to meet the needs of different scenes and atmospheres, while also contributing to energy conservation. In a specific implementation, the circuit board 21 is electrically connected to the first switch 12 and the second switch 13 through a wire passing through the lamp tube 1. The first switch 12 and the second switch 13 can be configured as a toggle switch or a push switch.

[0035] Reference Figure 1-Figure 5 As shown, a waterproof gasket 4 is further provided between the lamp housing 1 and the tapered connector 3 to effectively prevent external moisture from penetrating through the connection between the lamp housing 1 and the tapered connector 3, protecting the internal electronic components of the garden light from moisture, improving the product's waterproof performance, extending its service life, and ensuring stable operation in outdoor environments. The light source module 2 includes an upper cover 23 disposed above the fixing base 221 and covering the fixing base 221 and the circuit board 21. The light source module 2 also includes a light-transmitting plate 24 disposed below the circuit board 21 and fixedly connected to the fixing base 221. The light-transmitting plate 24 protects the circuit board 21 and the internal components of the light source module 2 while allowing light to pass through to achieve a lighting effect. In practice, users can also select a light-transmitting plate 24 with different lighting effects, such as transparent, translucent, or corrugated. To further conserve energy, the upper cover 23 can be configured to contain a solar panel, utilizing solar energy to power the garden light, achieving energy conservation and environmental protection.

[0036] like Figure 1 、 Figure 4-Figure 6As shown, further, the garden light of this case also includes an internal hollow mounting tube 5 for installation on the ground, and the mounting tube 5 is used to provide a certain support height, which is suitable for courtyard, road or lawn lighting scenes. The lamp tube 1 is completely embedded in the mounting tube 5, and the conical connector 3 abuts the upper end of the mounting tube 5. As another embodiment of this case, a number of grooves 14 are equidistantly provided on the outer peripheral wall of the lamp tube 1, and at least two screw holes 51 corresponding to the grooves 14 are symmetrically provided on the peripheral wall of the mounting tube 5. During specific implementation, the user uses a bolt to pass through the screw hole 51 and abut against the groove 14 to connect and fix the mounting tube 5 to the lamp tube 1. The user can also change the relative position of the lamp tube 1 and the mounting tube 5 by rotating the lamp tube 1, and correspond the screw hole 51 to the groove 14 at different positions of the lamp tube 1, and fix it by bolts to adjust the illumination direction of the second LED lamp bead 212. This method facilitates adjustment and, in conjunction with the multiple equally spaced grooves 14, provides a wider range of illumination directions for the second LED lamp bead 212, offering another adjustment method. This adjustment method allows the illumination direction of the second LED lamp bead 212 to be adjusted directly from the outside of the mounting tube 5, eliminating the tedious process of disassembly and assembly, making adjustment more convenient. Users can refer to this embodiment and adjust the bolts 32 and annular grooves 11 between the tapered connector 3 and the lamp barrel 1 to achieve different effects, or they can adjust them separately for specific purposes.
