Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an ambient light. Background Technology

[0002] As people's quality of life improves, ambient lighting is widely used in home lighting, stage entertainment scene decoration lighting and other fields because it can create specific light and shadow effects and enhance the atmosphere of a space.

[0003] In existing technologies, to achieve dynamic lighting effects, some ambient lights incorporate one or more rotatable water ripple sheets, light effect sheets, or similar structures along the light path of the light source. Light passes through these water ripple sheets and is then projected into the external space via a focusing lens or projection lens, creating visual effects such as flowing stars or rippling water.

[0004] However, existing technologies typically focus on projection imaging through a single light output direction, resulting in light and shadow effects concentrated mainly in front of the light fixture. The lighting effects are relatively simple, lacking spatial depth. Furthermore, the projection patterns of existing ambient lights are primarily formed from patterns on water ripples, leading to a rather limited range of pattern representations.

[0005] Therefore, there is a need to design an ambient light with rich lighting effects and good spatial atmosphere. Utility Model Content

[0008] Optionally, the lamp housing includes, in sequence along the light emission direction, a detachably connected rear shell, a light-transmitting ring, and a lampshade mounting ring. The light-transmitting ring constitutes the light-transmitting part; The rear end of the rear shell is detachably connected to the lamp holder; The headlight cover is detachably connected to the front end of the headlight cover mounting ring.

[0011] Optionally, the rear end of the rear shell is provided with a plurality of first snap-fit ​​slots in a circular array, and the front end of the lamp head is provided with a plurality of first snaps that engage with the first snap-fit ​​slots. The front end of the rear shell is provided with a number of second snap-fit ​​slots in a ring array, and the rear end of the light-transmitting ring is provided with a number of second snaps that engage with the second snap-fit ​​slots. The front end of the light-transmitting ring is provided with a plurality of third buckles in an annular array, and the rear end of the lampshade mounting ring is provided with a plurality of third buckle grooves that engage with the third buckles.

[0012] Optionally, the inner wall of the light outlet end of the lamp housing is provided with a plurality of supporting protrusions, and a plurality of pressure ribs are provided around the front end of the supporting protrusions along the light outlet direction. The rear end of the front lamp cover is provided with an annular flange, which engages between the support boss and the rib.

[0013] Optionally, the ambient light also includes a drive motor and a mounting bracket; The light source assembly includes a lamp plate installed inside the lamp housing with a through hole in the center, and two LED beads symmetrically arranged on the lamp plate; The drive motor and the mounting bracket are fixed to the bottom of the lamp panel; The drive shaft of the drive motor passes through the through hole and is fixedly connected to the optical interference sheet; The control motherboard is mounted on the mounting bracket and is electrically connected to the lamp board and the drive motor.

[0014] Optionally, the ambient light also includes a voltage regulating plate; the voltage regulating plate is installed in the mounting bracket and is electrically connected to the control main board, the light board and the drive motor.

[0017] Compared with the prior art, the advantages of this application are: This ambient light uses a light source component arranged sequentially inside the lamp housing, a rotatable light effect interference sheet placed in front of the light source component, and a front lamp cover with a first optical pattern installed at the light outlet of the lamp housing. This allows the light processed by the light effect interference sheet to be further modulated by the first optical pattern, thereby forming a dynamic and static composite light and shadow effect during the projection process that is different from that of a single light effect sheet. This increases the sense of layering of the projected pattern and effectively enriches the light effect expression of the ambient light.

[0018] In addition, because there is a light-transmitting part in the circumferential position of the lamp housing near the light outlet, some light can be transmitted outward along the circumference of the lamp housing. While achieving the effects of positive light output and projection, it also forms circumferential auxiliary light output, thereby enhancing the diffusion range and three-dimensionality of light in the space, making the overall spatial atmosphere softer and more uniform, and creating a better atmosphere.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used to distinguish multiple parts or structures with the same or similar structures, and do not indicate any special limitation on the arrangement order or connection relationship.

[0024] Please refer to Figures 1 to 10 This utility model embodiment provides an ambient light 100, including: a lamp head 1, a lamp housing 2, a control main board 3, a light source assembly 4, a light effect interference sheet 5, and a front lamp cover 6.

[0025] The lamp holder 1 serves as the electrical connection and / or mounting structure between the ambient light 100 and an external lamp holder (not shown in the figure). Optionally, in this embodiment, the lamp holder 1 has threads (not shown in the figure) on its outer periphery for threaded connection to the lamp holder (not shown in the figure). Of course, in other embodiments, the lamp holder 1 can also be a plug-in structure, achieving electrical connection and mounting through a pin or insert engaging with the lamp holder; or, the lamp holder 1 can be a snap-fit ​​structure, connecting to the lamp holder through a snap-fit ​​method; no specific limitations are made here.

[0026] The lamp housing 2 is a hollow shell, with its rear end connected to the lamp head 1 and its front end forming a light outlet a. In this embodiment, it can be understood that the rear end is the end closer to the lamp head 1, and the front end is the end farther away from the lamp head 1. The lamp housing 2 is a hollow shell that is roughly frustum-shaped from the rear end to the front end; its internal hollow space is used to accommodate the control main board 3, the light source assembly 4, and the light effect interference plate 5, and provides space for the rotation of the light effect interference plate 5 and the transmission of light.

[0027] The control motherboard 3 and the light source assembly 4 are electrically connected and both are housed within the lamp housing 2. Optionally, in this embodiment, the light source assembly 4 is an LED light source assembly 4. Of course, in other embodiments, the light source assembly 4 can also be a laser light source assembly 4. No specific limitation is made here. The control motherboard 3 is a PCB circuit board used to control the power supply and lighting effects of the light source assembly 4. The specific control method can adopt existing mature technologies, which will not be described in detail here.

[0028] The light effect interference plate 5 is rotatably disposed within the lamp housing 2 and located in the light emission path of the light source assembly 4. Optionally, in this embodiment, the light effect interference plate 5 is an optical lens with a flat rear surface and an uneven interference texture on the front surface. Specifically, the light effect interference plate 5 is a circular water ripple plate. Of course, in other embodiments, the light effect interference plate 5 can also be a cloud-pattern plate or an aurora-pattern plate; no specific limitation is made here. When the LED light source assembly 4 is turned on, the light effect interference plate 5 can rotate relative to the axis of the lamp housing 2, thereby producing a dynamic change effect in the transmitted light.

[0029] The headlight cover 6 is installed at the light outlet a of the lamp housing 2, and a first optical pattern 612 is provided on the headlight cover 6. Understandably, the first optical pattern 612 can be a star pattern, constellation, figure, or animal, etc. After light passes through the headlight cover 6, it can project the first optical pattern 612 into the external space. In this way, the dynamic light processed by the light effect interferometer 5 is further modulated by the first optical pattern 612, thereby forming a dynamic and static composite light and shadow effect during the projection process, increasing the sense of layering of the projected pattern, and effectively enriching the light effect expression of the ambient light 100.

[0030] The lamp housing 2 has a light-transmitting section at a circumferential position near the light outlet a. This allows some light to be transmitted outward along the circumference of the lamp housing 2, achieving both direct light output and projection effects while forming circumferential auxiliary light output. This enhances the diffusion range and three-dimensionality of the light in the space, making the overall spatial atmosphere softer and more uniform, and creating a better atmosphere.

[0031] To facilitate assembly and maintenance, and to enhance the flexibility of light effect expression, please optionally refer to... Figure 4 and Figure 5 In this embodiment, the lamp housing 2 includes, along the light emission direction, a detachably connected rear housing 21, a light-transmitting ring 22, and a lampshade mounting ring 23. The light-transmitting ring 22 constitutes the aforementioned light-transmitting part. The rear end of the rear housing 21 is detachably connected to the lamp head 1; the front lampshade 6 is detachably connected to the front end of the lampshade mounting ring 23. This modular design of the lamp housing 2 facilitates the assembly, disassembly, and maintenance of each component. Simultaneously, the light-transmitting ring 22, as a separate light-transmitting part, allows for the use of different materials, light transmittance, or structural forms according to different design requirements, thereby achieving different circumferential light transmission effects and enhancing the adjustability and versatility of the ambient light 100 in creating spatial atmosphere. Of course, in other embodiments, the lamp housing 2 can also be an integral structure; no specific limitations are imposed here.

[0032] Furthermore, in this embodiment, the inner wall of the light-transmitting ring 22 is provided with a second optical pattern (not shown in the figure), thereby enhancing the diversity of the ambient light 100 in creating spatial atmosphere. Understandably, the second optical pattern can be a regular or irregular textured structure, including but not limited to striped, wavy, dotted, grid-like, radial, or gradient patterns; or, the second optical pattern can be a decorative pattern with thematic features, such as starlight, cloud patterns, halos, or geometric shapes; no specific limitations are imposed here.

[0033] Alternatively, please refer to Figure 5 and Figure 6 In this embodiment, the headlight cover 6 has a double-sided flattened hemispherical structure, including a central hemispherical light-transmitting part 61 and opaque side parts 62 on both sides of the hemispherical light-transmitting part 61. The inner surface of the hemispherical light-transmitting part 61 is provided with an uneven refractive texture 611 for secondary refraction of light after passing through the light effect interference sheet 5, so that the light undergoes a change in the refraction angle during transmission, thereby enriching the directionality and layering of the light effect. The first optical pattern 612 is a star pattern set on the uneven refractive texture 611. When light passes through the light effect interference sheet 5 and illuminates the light-transmitting part of the headlight cover 6, the light undergoes secondary refraction and is then projected into space to form a composite light and shadow effect that combines movement and stillness, thereby increasing the layering and three-dimensionality of the light and shadow while forming a star projection in the forward direction. Of course, in other embodiments, the overall shape of the headlight cover 6 can also be a complete hemisphere; the uneven refractive texture 611 of the hemispherical light-transmitting part 61 can be a refractive structure of different depths or shapes, such as convex, wavy, sawtooth or random texture, to produce different refractive effects; no specific limitation is made here.

[0034] To enable detachable assembly between the rear housing 21, the light-transmitting ring 22, and the lampshade mounting ring 23, optionally, please refer to... Figure 4 , Figures 8 to 10In this embodiment, the rear end of the rear shell 21 is provided with a plurality of first snap-fit ​​slots 211 in a circular array, and the front end of the lamp head 1 is provided with a plurality of first snaps (not shown in the figure) that engage with the first snap-fit ​​slots 211. Thus, the rear shell 21 can be quickly and detachably installed with the lamp head 1. The front end of the rear shell 21 is provided with a plurality of second snap-fit ​​slots 212 in a circular array, and the rear end of the light-transmitting ring 22 is provided with a plurality of second snaps 221 that engage with the second snap-fit ​​slots 212; thus, the rear shell 21 can be quickly and detachably installed with the light-transmitting ring 22. The front end of the light-transmitting ring 22 is provided with a plurality of third snaps 222 in a circular array, and the rear end of the lamp cover mounting ring 23 is provided with a plurality of third snap-fit ​​slots 231 that engage with the third snaps 222; thus, the light-transmitting ring 22 can be quickly and detachably installed with the lamp cover mounting ring 23. Of course, in other embodiments, the relative positions of the first latching groove 211 and the first latch, the second latching groove 212 and the second latch 221, and the third latching groove 231 and the third latch 222 can be interchanged, or a detachable method such as a thread can be used, and no specific restrictions are made here.

[0035] To enable the detachable installation of the headlight cover 6 and the headlight cover mounting ring 23, optionally, please refer to... Figure 9 and Figure 10 In this embodiment, the inner wall of the light outlet a end of the lamp housing 2 is provided with four supporting protrusions 232, and four pressure ribs 233 are provided around the front end of the supporting protrusions 232 along the light emission direction. Specifically, in this embodiment, the supporting protrusions 232 and pressure ribs 233 are axially spaced apart from each other in the lamp cover mounting ring 23 and are axially staggered. The rear end of the front lamp cover 6 is provided with an annular flange 63, and the annular flange 63 of the supporting protrusions 232 engages between the supporting protrusions 232 and the pressure ribs 233. In this way, the front lamp cover 6 can be directly snapped into the supporting protrusions 232 and the pressure ribs 233. Of course, in other embodiments, the number of supporting protrusions 232 and pressure ribs 233 is not limited to four, but can also be three, five or more, and no specific limitation is made here.

[0036] Alternatively, please refer to Figure 2In this embodiment, the ambient light 100 further includes a drive motor 7 and a mounting bracket 8. The light source assembly 4 includes a lamp plate 41 and two LED beads 42. The lamp plate 41 has a through hole o1 at its center and is installed inside the lamp housing 2. Specifically, the lamp plate 41 is installed inside the lamp housing 2 by screws (not shown in the figure). The two LED beads 42 are symmetrically arranged on the lamp plate 41. The drive motor 7 and the mounting bracket 8 are fixed to the bottom of the lamp plate 41. Specifically, the mounting bracket 8 has mounting studs 81, the drive motor 7 has a first mounting hole 71 corresponding to the screw hole o3 in the mounting stud 81, and the lamp plate 41 has a second mounting hole o2 corresponding to the screw hole o3 in the mounting stud 81. Thus, the mounting bracket 8 and the drive motor 7 can be fixed to the bottom of the lamp plate 41 by the same set of screws (not shown in the figure). The drive shaft of the drive motor 7 passes through the through hole o1 and is fixedly connected to the light effect interference plate 5, thereby driving the rotation of the light effect interference plate 5. The control board 3 is mounted on the mounting bracket 8 and electrically connected to the lamp board 41 and the drive motor 7 to control the operation of the lamp board 41 and the drive motor 7.

[0037] Alternatively, please refer to Figure 3 In this embodiment, the ambient light 100 also includes a voltage regulating plate 9. The voltage regulating plate 9 is installed in the mounting bracket 8 and is electrically connected to the control main board 3, the lamp board 41, and the drive motor 7. Optionally, the voltage regulating plate 9 is a 5V voltage regulating plate. In this way, the function of the originally external power adapter can be integrated into the lamp housing 2, realizing the direct conversion of mains power to 5V low-voltage power for the entire lamp. This solves the problems of existing ambient lights 100 relying on external adapters, inconvenient installation, and low integration, and significantly improves the safety, convenience, and practicality of the lamp.

[0038] To facilitate the adjustment of the ambient light 100's functions, the ambient light 100 may optionally include an external control device (not shown in the figure). The control motherboard 3 has a light control circuit (not shown in the figure) and a wireless signal receiving unit (not shown in the figure). The light control circuit is used to control the power supply of the light source component 4 when the light is switched on and off, thereby achieving a smooth and gradual change in the brightness of the light panel 41. Specifically, when the light is turned on, the light control circuit gradually increases the power supply current or PWM duty cycle, so that the brightness of the light source changes smoothly from low to high; when the light is turned off, it gradually decreases the power supply current or PWM duty cycle, so that the brightness of the light source decreases smoothly from high to low. In this way, the user's visual experience is more comfortable, while reducing the impact of sudden changes in light on the spatial atmosphere. Specifically, the implementation of this function can refer to existing technologies, which will not be elaborated on here. Optionally, the external control device is an APP or a remote control, used to send control signals to the wireless signal receiving unit. Specifically, the external control device sends control signals to the wireless signal receiving unit, and the control motherboard 3 controls the operation of the light source component 4 and the drive motor 7 according to the control signals, which can refer to existing technologies, which will not be elaborated on here. In this way, the working status of the ambient light 100 can be adjusted remotely through the control device, making it easy to operate.
