Description

Technical Field

[0001] This utility model particularly relates to a lawn lighting device with independent control of multiple zones. Background Technology

[0002] Traditional lawn lights generally employ an integrated light-emitting structure, meaning the light source module, lampshade, and support base are designed as a single unit. Specifically, existing lawn lights typically fix a single LED panel or strip inside the lampshade, with only one power input and a single driver circuit for the entire light. When powered on, all light sources illuminate simultaneously, and the entire lampshade transmits light evenly, forming a continuous, uninterrupted light-emitting surface. While this structure is simple to manufacture and low in cost, it suffers from the following technical drawbacks in practical applications:

[0003] Existing lawn lights use a single, encapsulated LED panel where all LED chips share the same drive current. This prevents independent switching between "full brightness / partial brightness / off" for different areas based on specific lighting needs. For example, when pedestrian traffic is low late at night or when only partial illumination of the roadside is required, the entire light fixture still needs to be turned on, resulting in unnecessary energy consumption. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a lawn lighting device with multi-zone independent control.

[0005] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0006] A multi-zone independently controllable lawn lighting device includes a support base for fixed installation on the lawn and a lamp head detachably installed on the support base. The lamp head includes a base, a lamp holder, and a connecting part connecting the base and the lamp holder. The connecting part is circumferentially spaced with multiple partition plates, which divide the light-emitting area of ​​the lamp head into multiple independent light-emitting zones. Each light-emitting zone is provided with an independent light source component. Each light source component is electrically connected to a control device for independently controlling the light-emitting state of each light-emitting zone, so as to realize full or partial light emission of each light-emitting zone.

[0007] Preferably, the connecting part has an inwardly recessed arc-shaped light guide surface, and the light emitted by the light source assembly is directly projected onto the arc-shaped light guide surface, and after reflection and / or refraction, it is led outward from the light-emitting area.

[0008] Preferably, the lamp holder includes an upper housing and a lower housing, which are locked together by a plurality of locking members; an installation cavity is formed between the upper housing and the lower housing, and an aluminum substrate and a lamp plate are provided in the installation cavity, and the light source assembly is installed on the lamp plate; the locking members pass through the lower housing, the aluminum substrate and the lamp plate in sequence and are threadedly connected to the upper housing.

[0009] Preferably, the lower housing is divided into light-transmitting areas that correspond one-to-one with the light-emitting areas, and each light-transmitting area has a light-emitting groove for light diffusion.

[0010] Preferably, a positioning groove is provided between adjacent light-transmitting areas, and a positioning protrusion is provided on the partition plate to cooperate with the positioning groove. The positioning protrusion and the positioning groove are inserted and cooperated to realize the positioning and installation of the light-emitting area.

[0011] Preferably, the lower housing has a mounting block on the side facing the upper housing, the positioning groove is provided on the mounting block, and the aluminum substrate has a first opening that cooperates with the mounting block for positioning.

[0015] This invention, through the design of multiple independently controllable light-emitting areas and corresponding light source components, allows for the selection of full-brightness or partial-lighting modes according to scene requirements, achieving dynamic light effect changes. Compared to single-light-emitting lawn lights, this lawn light is suitable for lighting needs in different scenes and supports multiple lighting mode combinations. In addition, the insertion and engagement of the positioning protrusion and positioning groove completes the alignment of the light area during the assembly stage, eliminating random errors caused by manual alignment.

The connecting part 23 is circumferentially spaced with multiple partition plates 3, which divide the light-emitting area of ​​the lamp head 2 into multiple independent light-emitting zones. Each light-emitting zone is provided with an independent light source component. Each light source component is electrically connected to a control device for independently controlling the light-emitting state of each light-emitting zone, so as to realize the full or partial light emission of each light-emitting zone.

[0031] Furthermore, the connecting part 23 has an inwardly recessed arc-shaped light guide surface 231, and the light emitted by the light source assembly is directly projected onto the arc-shaped light guide surface 231, and is led outward from the light-emitting area after reflection and / or refraction.

[0032] Furthermore, the lamp holder 22 includes an upper housing 221 and a lower housing 222, which are locked together by a plurality of locking members 1-1. An installation cavity is formed between the upper housing 221 and the lower housing 222, and an aluminum substrate 223 and a lamp plate 224 are provided in the installation cavity. The light source assembly is installed on the lamp plate 224. The locking member 1-1 passes through the lower housing 222, the aluminum substrate 223 and the lamp plate 224 in sequence and is threadedly connected to the upper housing 221.

[0033] Furthermore, the lower housing 222 is divided into light-transmitting areas corresponding to the light-emitting areas, and each light-transmitting area has a light-emitting groove 4 for light diffusion.

[0034] Furthermore, a positioning groove 5 is provided between adjacent light-transmitting areas, and a positioning protrusion 51 is provided on the partition plate 3 to cooperate with the positioning groove 5.

[0037] Furthermore, the support base 1 is provided with an installation port 9 for inserting the lamp holder 2.

[0038] The working principle of this utility model is as follows:

[0039] like Figure 1 As shown, the support base 1 is used to fix it on the lawn. As an example of embodiment 1, this application illustrates the design concept by using a design with four light-emitting zones. As can be seen from the figure, four partition plates 3 are circumferentially spaced on the connecting part 23 of the lamp head 2. That is, two adjacent partition plates 3, the upper surface of the base 21, and the lower surface of the lamp holder 22 together form a single light-emitting zone. Each light-emitting zone corresponds to a light source component; that is, four light source components are provided on the lamp plate 224. The four light source components are electrically connected to a control device. The control device can control the four light source components to emit light together, or only some of the light source components to emit light. The light source components can be implemented using LED beads. The light effect is... Figure 5-8 As shown, Figure 5 An illustration showing the effect of a single light source component emitting light (the shaded areas in the image represent non-emitting regions). Figure 6 This is a diagram showing the effect of two light source components emitting light. Figure 7 An illustration showing the effect of three light source components emitting light. Figure 8 This diagram illustrates the effect of four light source components emitting light. By designing multiple independently controllable light-emitting zones and corresponding light source components, this invention allows for selection of full-brightness or partial-brightness modes according to scene requirements, achieving dynamic light effect changes. Compared to single-emitting lawn lights, this lawn light is suitable for different lighting needs and supports combinations of various lighting modes.

[0040] Based on the above technical solution, the connecting part 23 of this application has an inwardly recessed arc-shaped light guide surface 231. The light emitted by the light source assembly is directly projected onto the arc-shaped light guide surface 231, and after reflection and / or refraction, it is led outward from the light-emitting area. The arc-shaped light guide surface 231 makes the light distribution more uniform and eliminates the "light spot" phenomenon of traditional lamps. In addition, since lawn lights are mostly used outdoors, the arc-shaped light guide surface 231 can effectively guide rainwater.

[0041] Based on the above technical solution, the lamp holder 22 is designed as an upper housing 221 and a lower housing 222, which are locked and fixed by multiple locking members 1-1. A mounting cavity is formed between the upper housing 221 and the lower housing 222, and an aluminum substrate 223 and a lamp plate 224 are provided in the mounting cavity. The independent light source assembly is mounted on the lamp plate 224. The locking member 1-1 passes through the lower housing 222, the aluminum substrate 223 and the lamp plate 224 in sequence and is threadedly connected to the upper housing 221. The lower housing 222 is divided into four light-transmitting areas, each of which corresponds to a light-emitting area. Four light source assemblies can be provided on the lamp plate 224. The light from each light source assembly passes through the light-transmitting areas on the aluminum substrate 223 and the lower housing 222 in sequence, and is then projected into the light-emitting area. Each light-transmitting area of ​​this application has a light-emitting groove 4 for light diffusion. Through the depth and other structures of the light-emitting groove 4, better diffuse reflection and more uniform brightness can be achieved.

[0042] Based on the above technical solution, the installation and cooperation between the partition plate 3, the lower housing 222, the aluminum substrate 223, and the lamp plate 224 can be as follows: A mounting block 6 is provided protruding upwards on the lower housing 222, and a positioning groove 5 is provided on the mounting block 6. A positioning protrusion 51 is provided on the partition plate 3. During installation, the positioning protrusion 51 is inserted into the positioning groove 5, ensuring that the light-transmitting area of ​​the lower housing 222 corresponds one-to-one with the light-emitting area. Then, the mounting block 6 is positioned at the first opening 7 on the aluminum substrate 223, and the second opening 8 on the lamp plate 224 is also positioned at the mounting block 6. Finally, one end of the locking member 1-1 is sequentially inserted through the lower housing 222, the aluminum substrate 223, and the lamp plate 224, and finally threaded onto the upper housing 221. The mounting block 6 passes through the first opening 7 and the second opening 8 sequentially and abuts against the upper housing 221. This design facilitates the inspection and installation of the lawn light. As an embodiment 1, the locking member 1-1 can be implemented using screws. The positioning protrusion 51 and the positioning groove 5 of this utility model are connected and the light area is aligned during the assembly stage, eliminating random errors caused by manual alignment; the through-type design of the locking part 1-1 makes the aluminum substrate 223, the lamp plate 224 and the lower housing 222 form a rigid whole, and the vibration during transportation and installation will not cause the light area to shift.

[0043] Based on the above technical solution, the support base 1 is provided with an installation port 9 for inserting the lamp holder 2, which makes it more convenient to disassemble and replace the lamp holder 2.

[0044] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
