Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a focusing structure and a lighting device. Background Technology

[0002] Driven by functional requirements, lighting fixtures have evolved from single-light-domain to dynamic scene adaptation, meaning they have developed from conventional lighting fixtures into continuously zoomable fixtures, maximizing space efficiency and achieving precise light distribution and optimized energy consumption. For example, the utility model patent application with application number CN202222640677.4 describes a design where at least three sets of protrusions are provided on the outside of the optical component, and at least three sets of guide grooves are provided on the annular fixing frame. This allows the optical component to move up and down axially via a rotating disk. However, since the rotating disk needs to rotate relative to the annular fixing frame with the axial direction as the rotation axis, a high-precision fit between the rotating disk and the annular fixing frame is required, resulting in high processing costs. Alternatively, if a large gap is left between the rotating disk and the annular fixing frame support, the optical component may be prone to eccentric offset during rotation, affecting the light output effect.

[0030] This application provides a focusing structure. The focusing structure includes an optical component, a light source component, a housing, a linear moving component, and at least one adjusting component. The housing has a mounting groove, and both the light source component and the optical component are disposed within the mounting groove. The light source component emits light, which is configured to at least partially enter the optical component and exit outside the mounting groove through the optical component. Both the linear moving component and the adjusting component are disposed within the mounting groove. At least one of the optical component and the light source component is rotatably and / or oscillatingly mounted on the housing, and the optical component or the light source component is connected to the side of the linear moving component away from the housing.

[0031] The aforementioned focusing structure allows both the light source and optical components to be housed within the mounting groove.

[0032] To better understand the focusing structure of this application, the following further explanation is provided:

[0033] Please refer to the following: Figures 1 to 2One embodiment of the focusing structure 10 includes an optical element 100, a light source 200, a housing 300, a linear moving element 400, and at least one adjusting element 500. The housing 300 has a mounting groove 301. Both the light source 200 and the optical element 100 are disposed within the mounting groove 301. The light source 200 emits light, which is configured to at least partially enter the optical element 100 and exit through the optical element 100 to the outside of the mounting groove 301. Both the linear moving element 400 and the adjusting element 500 are disposed within the mounting groove 301. At least one of the optical element 100 and the light source 200 is rotatably and / or oscillatingly mounted on the housing 300. Either the optical element 100 or the light source 200 is connected to the side of the linear moving element 400 away from the housing 300. The adjusting element 500 protrudes from the side of the linear moving element 400 near the housing 300 and is slidably connected to the housing 300. The sliding direction of the adjusting element 500 is parallel to the depth direction of the mounting groove 301.

[0034] The aforementioned focusing structure 10 allows both the light source 200 and the optical element 100 to be housed within the mounting groove 301. At least one of the optical element 100 and the light source 200 is rotatably and / or oscillatingly mounted on the housing 300, enabling adjustment of the illumination angle of the focusing structure 10. The optical element 100 or the light source 200 is connected to the side of the linear moving member 400 away from the housing 300. The adjusting member 500 protrudes from the side of the linear moving member 400 near the housing 300 and is slidably connected to the housing 300. The sliding direction of the adjusting member 500 is parallel to the depth direction of the mounting groove 301, so that the linear moving member 400 slides towards or away from the depth direction of the mounting groove 301, thereby causing the light source member 200 or the optical member 100 to slide towards or away from the depth direction of the mounting groove 301 via the linear moving member 400. The linear moving member 400 does not need to rotate relative to the housing 300, which reduces the processing accuracy requirements, thereby reducing the processing cost of the focusing structure 10, and ensuring the stable light output effect of the focusing structure 10.

The transition portion 520a is connected to the side of the connecting portion 510a near the housing 300 and passes through the sliding area 302. The locking portion 530a is connected to the side of the transition portion 520a away from the connecting portion 510a. The side of the locking portion 530a near the transition portion 520a abuts against the housing 300 and is slidably connected to the housing 300, further ensuring the locking stability and sliding stability of the adjusting member 500 on the housing 300.

One end of each of the two elastic arms 520b is connected to the side of the fixing part 510b near the housing 300. The two elastic arms 520b pass through the sliding area 302 together, and the other end of each elastic arm 520b is configured to elastically deform when moving towards the other elastic arm 520b, and can move away from the other elastic arm 520b to return to its original position. Further, the side of each elastic arm 520b away from the other elastic arm 520b rests against the sliding area 302. See also Figure 2 and Figure 3It can be understood that the side of each elastic arm 520b away from the other elastic arm 520b abuts against the sliding area 302, that is, the side of each elastic arm 520b away from the other elastic arm 520b abuts against the sliding area 302 and exerts a pushing force on the sliding area 302. Further, the sliding area 302 is a sliding hole; the side of each elastic arm 520b away from the other elastic arm 520b abuts against the wall of the sliding hole. Further, the two elastic arms 520b together form a transition portion 520a and a locking portion 530a, that is, each elastic arm 520b is formed by connecting 1 / 2 of the transition portion 520a and 1 / 2 of the locking portion 530a, realizing convenient assembly and disassembly of the adjusting member 500 on the housing 300, and improving the assembly and maintenance convenience of the focusing structure 10. Furthermore, the fixing part 510b and the two elastic lever arms 520b are integrally formed, which improves the structural stability and compactness of the focusing structure 10, and also improves the processing efficiency of the focusing structure 10.
