In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0031] In response to the problem that the reflector in the related art cannot be adjusted, the present application sets the reflector as a first shell and a second shell that are threadedly connected, and adjusts the reflective effect by adjusting the relative position between the first shell and the second shell, thereby achieving equivalent convenient adjustment.

[0032] The following describes an adjustable reflector according to an embodiment of the present application with reference to the accompanying drawings. It should be noted that the first direction is shown in the up-down direction in the accompanying drawings.

[0033] Reference Figures 1 to 3 According to an embodiment of the utility model, an adjustable reflector includes a first shell 100 and a second shell 200. The first shell 100 includes a fixing portion 120 and a first connecting portion 110. The fixing portion 120 is used to connect the lamp body. The fixing portion 120 is connected to the first connecting portion 110. The first connecting portion 110 is provided with a first hole 111. The first hole 111 is used to set a light source. The outer surface of the first connecting portion 110 is provided with a first thread 112. The second shell 200 includes a reflecting portion 210 and a second connecting portion 220. The second connecting portion 220 is provided with a second hole 221. The second connecting portion 220 is provided with a second thread 222. The second thread 222 is located in the second hole 221. The second thread 222 is threadedly connected to the first thread 112. The second connecting portion 220 can move in a first direction relative to the first shell 100. The reflective portion 210 is connected to the second connecting portion 220 . The reflective portion 210 can protrude from the first housing 100 in the first direction. The reflective portion 210 and the fixing portion 120 are located at opposite sides of the first connecting portion 110 in the first direction.

[0034] Through the threaded connection of the first thread 112 and the second thread 222, the relative positions of the first shell 100 and the second shell 200 in the first direction can be adjusted to adjust the regulating effect of the reflective portion 210 on the light output of the light source, thereby facilitating the realization of different lighting requirements, and enabling the first shell 100 to be retracted into the interior of the second shell 200 for storage, thereby facilitating the transportation or storage of the reflector.

[0035] Specific reference Figure 2The wall of the reflecting portion 210 is relatively inclined to the second connecting portion 220, and the wall of the reflecting portion 210 defines a light channel connected to the second hole 221. The inclination of the wall makes the light channel have a change in cross-sectional area, and the cross-sectional area on the side relatively far from the second connecting portion 220 is larger than the cross-sectional area on the side relatively close to the second connecting portion 220, so that the reflecting portion 210 is trumpet-shaped, and the reflection of light by the inclined wall plays a role in adjusting the light effect.

[0036] The change in position of the first connection part 110 relative to the second connection part 220 in the first direction is equivalent to the change in position of the reflective part 210 relative to the fixing part 120 in the first direction, and the light emission effect is adjusted by the coverage of the path of the light after the light is emitted from the first hole 111 by the reflective part 210. In addition, since the second shell 200 is equivalent to being sleeved on the outside of the first shell 100, by adjusting the positional relationship between the first connection part 110 and the second connection part 220, the first connection part 110 can also be equivalent to being sleeved inside the reflective part 210, thereby improving the spatial recombination rate and achieving a storage effect.

[0037] The first hole 111 of the first connection portion 110 may also be configured as a through hole with a variable aperture, so that the cross section of the first hole 111 is also trumpet-shaped, thereby achieving the effect of adjusting the light effect.

[0038] Reference Figure 3 and Figure 4 In some embodiments, the thread profiles of the first thread 112 and the second thread 222 are trapezoidal. The trapezoidal thread profile enables the matching wall surfaces of the first thread 112 and the second thread 222 to be tightly pressed against each other, and the thread roots have high strength and strong concentricity, resulting in a stable connection and a long service life, which is conducive to maintaining a stable posture of the reflector.

[0039] Reference Figure 2 In some embodiments, the first connection portion 110 has a set size L in the first direction, and the first thread 112 has a set pitch P, satisfying: 2L≤P≤4L. By controlling the pitch of the first thread 112, the relationship between the relative rotation angle of the first connection portion 110 and the second connection portion 220 and the relative position of the first connection portion 110 and the second connection portion 220 in the first direction can be adjusted. In the case of 2L≤P, a smaller relative rotation angle between the first connection portion 110 and the second connection portion 220 can achieve a larger change in the first direction. In the case of P≤4L, it can be ensured that the first thread 112 and the second thread 222 have sufficient inclination for rotational matching, and ensure that there is sufficient matching path to achieve a stable connection. P can be selected as 2L, 2.5L, 3L, 3.5L, 4L or any value between 2L and 4L.

[0040] Taking P=3L as an example, the first connection portion 110 and the second connection portion 220 only need to rotate 120° relative to each other to enable the first shell 100 and the second shell 200 to move from Figure 3 The relative position movement in Figure 4 The relative position in the middle, that is, the first connection part 110 and the second connection part 220 move from the lower end surface to the upper end surface of the first connection part 110 and the second connection part 220, realizes the conversion between the fully retracted state and the fully ejected state. The user does not need to drive the first connection part 110 and the second connection part 220 to rotate too much relative to each other, and the operation is convenient and quick.

[0041] Reference Figure 1 In some embodiments, the first thread 112 includes a plurality of thread segments 113, each thread segment 113 is evenly arranged along the circumference of the first housing 100, and the arrangement of the plurality of thread segments 113 can increase the connection nodes between the first thread 112 and the second thread 222 to improve the connection strength and matching stability. Among them, the second thread 222 is arranged corresponding to the first thread 112, that is, the second thread 222 is also provided with a plurality of matching thread segments 113 to match with each thread segment 113 of the first thread 112 one by one.

[0042] Furthermore, the first thread 112 includes three thread segments 113, and the thread segments 113 are equidistantly arranged in the circumferential direction of the first shell 100, that is, the thread segments 113 are equidistantly distributed with a difference of 120° relative to the center point of the first connecting portion 110. The three thread segments 113 can ensure the stable connection between the first thread 112 and the second thread 222, and facilitate mold demolding and processing during the production process, thereby reducing production difficulty and cost.

[0043] Reference Figures 1 to 3 In some embodiments, the first connecting portion 110 is provided with a first magnetic component 130, and the second connecting portion 220 is provided with a second magnetic component 230. When the first magnetic component 130 and the second magnetic component 230 move relative to each other as the first shell 100 and the second shell 200 move, the first magnetic component 130 and the second magnetic component 230 are attracted to each other to provide a certain pre-tightening force and serve as a prompt to prompt the operator to rotate into place.

[0044] Among them, a plurality of first magnetic members 130 may be provided, and each first magnetic member 130 is arranged in sequence along the extension direction of the first thread 112, so that when a single second magnetic member 230 moves to be opposite to each first magnetic member 130, they can all be mutually attracted to provide prompts and preload force at the set position, so as to facilitate quantitative adjustment. In some embodiments, a plurality of second magnetic members 230 may also be provided, and each second magnetic member 230 is arranged in sequence along the extension direction of the second thread 222, so that when a single first magnetic member 130 moves to be opposite to each second magnetic member 230, they can all be mutually attracted to each other.

[0045] Reference Figure 3 As another improvement of the above scheme, the first magnetic member 130 is arranged at one end of the first connecting part 110 close to the fixing part 120, and the second magnetic member 230 is arranged at one end of the second connecting part 220 away from the reflective part 210, so that when the first connecting part 110 and the second connecting part 220 are relatively rotated and the end surfaces are flush, an adsorption force is provided for prompting, and the end surfaces are kept in a flush posture, so as to prompt the operator that the rotation has been made to the storage state, and the risk of the first thread 112 and the second thread 222 being disengaged from the fit is reduced, thereby reducing the risk of bumping the lamp body or the first shell 100 and the second shell 200 being disengaged. Among them, in the embodiment where the number of the first magnetic member 130 is set to be multiple, the corresponding function can be achieved as long as there is one first magnetic member 130 located at one end of the first connecting part 110 close to the fixing part 120. In the embodiment where the number of the second magnetic member 230 is set to be multiple, the corresponding function can be achieved as long as there is one second magnetic member 230 located at one end of the first connecting part 110 away from the reflective part 210.

[0046] Reference Figures 1 to 3 In some embodiments, the first shell 100 further includes a limiting portion 140, which is connected to the first connecting portion 110. The limiting portion 140 is located on the side of the first connecting portion 110 that is away from the fixing portion 120. The limiting portion 140 is used to abut against the second connecting portion 220 to limit the movement of the first connecting portion 110 from the second connecting portion 220, thereby preventing the operator from accidentally detaching the second shell 200 from the first shell 100 when driving the second shell 200 to rotate relative to the first shell 100.

[0047] In some embodiments, the material of the first shell 100 is aluminum, which is convenient for cutting and processing, and can reduce the difficulty of processing. Aluminum has good thermal conductivity, and can facilitate heat dissipation, thereby reducing heat accumulation caused by the light source.

[0048] The lamp according to the embodiment of the utility model comprises a lamp body (not shown in the figure), a light source (not shown in the figure) and an adjustable reflector according to any of the above embodiments, the light source is connected to the lamp body, the fixing part 120 is connected to the lamp body, and the light source can emit light from the first hole 111. By using the adjustable reflector according to the embodiment of the present application, by adjusting the relative position of the first shell 100 and the second shell 200 in the first direction, the light emission effect of the light source after emitting light from the first hole 111 can be adjusted, so as to facilitate the use of the lamp.

[0049] The fixing part 120 and the lamp body can be connected by plugging, clamping or fastening with bolts or other pre-tightening parts. The light source can be inserted into the first hole 111 or arranged inside the lamp body, as long as light can be emitted from the first hole 111.

[0050] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model.
