Description

Technical Field

[0002] As modern living standards improve, people have higher demands for the functionality and comfort of indoor lighting equipment. In particular, special lighting products such as nightlights not only need to meet basic nighttime lighting needs, but also need to consider functions such as creating ambiance and protecting eye health.

[0004] In existing technologies, some attempts have been made to achieve multifunctional lighting through a dual-light source structure. For example:

[0005] Main light source + auxiliary light source combination: Some luminaires have a main light source in the center to provide basic lighting, and auxiliary light sources at the edges for ambient lighting. However, this type of design usually only distinguishes the switching of the two light sources and lacks optimized design of the light path, resulting in problems such as light interference or abrupt transitions when switching light effects.

[0006] Light guide plate structure: Some solutions use light guide plates to diffuse light, but ordinary light guide plates are usually flat or single curved surface structures, which cannot take into account both the wide-angle diffusion of the main light source and the layered light effect of the auxiliary light source, and it is difficult to avoid stray light.

The panel 12 and the bottom shell 11 are fixedly connected by tightening the fastening screw, and are separated and disassembled by loosening the fastening screw.

[0036] Furthermore, the inner bottom surface of the bottom shell 11 is provided with an upwardly protruding cylindrical mounting platform 7; the cylindrical mounting platform 7 is provided with a main light source mounting position, and the main light source 2 is fixedly mounted on the mounting position; the inner ring surface of the light guide structure 4 is clearance-fitted with the outer circumferential surface of the cylindrical mounting platform 7; the inner side of the panel 12 is provided with an annular pressure plate 8; when the panel 12 is assembled with the bottom shell 11, the annular pressure plate 8 presses and fixes the light guide structure 4 in the mounting groove 111.

[0037] Furthermore, the light guide structure 4 is integrally formed.

[0038] Furthermore, a light-transmitting gap is provided at the connection joint between the panel 12 and the bottom shell 11, and an annular light guide plate 9 is embedded in the light-transmitting gap. When the auxiliary light source 3 is working, the light is conducted through the annular light guide plate 9 and emitted uniformly from the outer edge of the panel 12.

[0039] The working principle of this utility model is as follows:

[0040] Both the main light source 2 and the auxiliary light source 3 are mounted on the housing 1 and arranged at intervals. The main light source 2 operates in the first mode, emitting light that enters the light guide structure 4 evenly. After diffusion by the light guide structure 4, it forms a soft and uniform light effect, providing basic illumination for the environment. This basic lighting mode can meet the user's lighting needs in general nighttime scenarios, such as simple lighting when getting up at night. The light is soft and not glaring, avoiding problems such as excessive light affecting the user's vision or disrupting the quiet atmosphere at night. The auxiliary light source 3 operates in the second mode, emitting light that, under the combined action of the light guide structure 4 and the light-shielding element 5, forms a layered light effect with a sense of depth. The addition of the auxiliary light source 3 enriches the nightlight's lighting modes, allowing the product to adapt to different usage scenarios and user needs, such as creating a warm and romantic atmosphere in the bedroom or serving as decorative lighting in the living room.

[0041] Based on the above technical solution, the structural cooperation principle of the light guide structure 4 and the light shielding element 5 is as follows: The light guide structure 4 is arranged around the periphery of the housing 1 and extends in a direction away from the housing 1 to form a stepped structure. This stepped structure consists of multiple light guide surfaces 41 spaced apart along the axial direction, and adjacent light guide surfaces 41 are connected by an inclined transition surface 42. The light guide structure 4 is manufactured using an integral molding method, which ensures its integrity and optical performance stability, avoids the problem of uneven light refraction and reflection that may occur due to the splicing of multiple parts, and improves the quality and performance consistency of the product. The outer surface design of the light guide structure 4 allows light to undergo multiple reflections and refractions, enhancing the mixing and diffusion effect of light and improving the uniformity and softness of the light effect. Its stepped design provides a basic structure for forming layered light effects. Different light guide surfaces 41 can guide and output light to different degrees, creating conditions for the subsequent shielding effect of the light shielding element 5. The light shielding element 5 is set on the transition surface 42, and its extension direction is consistent with the inclined direction of the transition surface 42. The light-shielding element 5 is detachably fixed to the transition surface 42 via a snap-fit ​​connection structure, which includes a slot 51 on the transition surface 42 and a latch 52 on the light-shielding element 5. This snap-fit ​​connection method has the advantages of reliable connection and convenient assembly and disassembly, allowing for quick operation when the light-shielding element 5 needs to be replaced or cleaned, thus improving the ease of product maintenance. The light-shielding element 5 blocks the light emitted by the auxiliary light source 3. By controlling the position, shape, and size of the light-shielding element 5, differences in brightness and light pattern can be created in the light output from different light guide surfaces 41, thereby producing a layered lighting effect with distinct layers. This layered lighting effect not only enhances the design and aesthetics of the product but also creates a richer, more comfortable, and personalized lighting environment, meeting users' pursuit of a high-quality lighting experience.

[0042] Based on the above technical solution, the installation and assembly method of the housing 1 can be as follows: The housing 1 consists of a bottom shell 11 and a front panel 12. The bottom shell 11 serves as a basic support structure, and its interior is provided with a mounting groove 111 for mounting other components. The inner bottom surface of the bottom shell 11 is designed with an upwardly protruding cylindrical mounting platform 7, which provides a positioning and stable mounting base for the main light source 2. The inner ring surface of the light guide structure 4 is clearance-fitted with the outer circumferential surface of the cylindrical mounting platform 7. This fit allows the light emitted by the main light source 2 to smoothly pass through the cylindrical mounting platform 7 and enter the interior of the light guide structure 4, reducing light loss and scattering during propagation and improving the utilization rate of light efficiency. The front panel 12 is provided with a light projection port 121 corresponding to the light guide structure 4. The shape and position of the light projection port 121 are carefully designed to ensure that the light is emitted uniformly outward without affecting the overall appearance of the product. When the annular pressure plate 8 on the inner side of the panel 12 is assembled with the bottom shell 11, it firmly presses the light guide structure 4 into the mounting groove 111, ensuring the installation stability of the light guide structure 4 and avoiding problems such as uneven light effect or light leakage caused by the loosening of the light guide structure 4. The bottom shell 11 and the panel 12 are connected by a detachable connection structure, which adopts a combination of threaded holes 6, through holes 61 and fastening screws. This threaded connection method has the characteristics of high connection strength and good stability, which can ensure the sealing and structural integrity of the shell 1. At the same time, it is easy to operate and can be disassembled and assembled without special tools, making it convenient for users to repair or replace internal components when needed.

[0043] As an example 2, such as Figure 6 As shown, taking a night light with one light-shielding element 5 as an example, a light-transmitting gap is provided around the connection between the night light panel 12 and the bottom shell 11, and an annular light guide plate 9 is embedded in the light-transmitting gap. When the auxiliary light source 3 is working, the light is conducted through the annular light guide plate 9 and emitted evenly from the outer edge of the panel 12. This unique design further enriches the lighting effect and visual aesthetics of the night light. The addition of the annular light guide plate 9 works closely with the existing structure to form a complete light effect optimization system. At the same time, the setting of the annular light guide plate 9 allows the light from the auxiliary light source 3 to be fully utilized in the horizontal direction, further improving the light utilization efficiency. This structural combination not only enhances the lighting functionality and artistry of the night light, but also optimizes the light effect performance of the auxiliary light source 3, bringing users a more comfortable, beautiful, and layered night lighting experience.

[0044] This utility model of a nightlight, through its unique structural design, achieves the dual functions of basic lighting and ambiance creation, meeting the higher demands of modern life for the functionality and comfort of indoor lighting equipment. It employs a dual-light source structure of a main light source 2 and an auxiliary light source 3, combined with a stepped light guide structure 4 surrounding the housing 1 and a light-shielding element 5 set on the transition surface 42. This not only provides soft and uniform light in basic lighting mode, but also allows the light output of the auxiliary light source 3 to be controlled via the light-shielding element 5 in ambiance creation mode, creating distinct lighting effects. Compared with traditional lamps, this design optimizes the light path, avoiding light interference and abrupt transitions, improving light utilization efficiency, and reducing stray light. The split design of the housing 1 and the detachable connection structure of each component, such as the snap-fit ​​connection of the light-shielding element 5 and the threaded connection between the housing 1 and the panel 12, enhance the structural stability and reliability of the product, while also improving the convenience of maintenance and use. Overall, this utility model of a nightlight demonstrates significant advantages in functionality, light quality, structural performance, and user experience, effectively solving many shortcomings of traditional nightlights.
