DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0038] like Figure 1-11 As shown, an adjustable assembly for exhibition lighting includes a combination cover 1 arranged on a truss, and the combination cover 1 is provided with:

[0039] The light-emitting unit comprises a light-emitting plate 51 movably arranged along a central axis, and a reflector 12 is arranged on the light-emitting plate 51;

[0040] The soft light lampshade 2 is arranged between the reflector 12 and the combined cover 1. The soft light lampshade 2 is driven to deform and block the reflector 12 to change the reflection range of the reflector 12.

[0041] Specifically, the combined cover 1 includes a bottom shell 10 and a connecting frame 11 which are rotatably connected to each other. A rotation damper is provided at the hinge point of the bottom shell 10 and the connecting frame 11 to control the angle of the bottom shell 10. The connecting frame 11 is installed on the truss through fasteners (the fasteners can be screws). The light-emitting panel 51 is movably arranged on the bottom shell 10. The reflector 12 is conical and is arranged on the light-emitting panel 51. The soft light lampshade 2 is elastic (the soft light lampshade 2 is made of silicone), one end of which is arranged on the reflector 12, and the other end is fixed on the combined cover 1. The soft light lampshade 2 is arranged on the bottom shell 10 through a connecting column 21.

[0042] In the above technical solution, when both soft light and direct light are required to be directed toward the exhibit, the connecting frame 11 is installed on the truss, and the light-emitting panel 51 is rotated to face the exhibit. Then, the soft light lampshade 2 is adjusted according to the size of the venue and the exhibit, and the soft light lampshade 2 is driven to deform toward the central axis of the reflector 12 and block the reflector 12. Fig. 9 As shown, when the reflector 12 is blocked, the range of direct light will be reduced, and at the same time, the soft light shade 2 is illuminated to increase the surrounding soft light. When stronger direct light is needed to highlight the exhibits, the range of the soft light shade 2 that blocks the reflector 12 is reduced to enhance the direct light and reduce the soft light. As shown in Figure 7, by reducing the number of lamps on the truss, it is easy to install and carry, and is particularly suitable for mobile exhibitions.

[0043] As an embodiment provided by the present invention, the combined cover 1 includes a bottom shell 10 and a limiting cover 31 moving along the central axis direction of the bottom shell 10 . The limiting cover 31 is driven to push against the soft light cover 2 to deform the soft light cover 2 .

[0044] Specifically, a connecting piece 101 is provided on the bottom shell 10, and an internal thread is provided on the connecting piece 101. An external thread 310 is provided on the outer wall of the limiting cover 31. The limiting cover 31 is controlled to move along the central axis direction of the bottom shell 10 through the threaded connection between the external thread 310 and the internal thread. When it is necessary to drive the soft light lampshade 2 to deform and move toward the central axis of the reflector 12, the limiting cover 31 is rotated to move toward the soft light lampshade 2, thereby pushing the soft light lampshade 2 to deform, so that the soft light lampshade 2 is deformed toward the central axis of the reflector 12 to block the reflector 12. At the same time, the deformed soft light lampshade 2 always has a rebound thrust, which assists in locking the threaded connection between the external thread 310 and the internal thread.

[0045] As an embodiment provided by the present invention, the soft light lampshade 2 is switched between the following three positions:

[0046] First station: the inner wall of the soft light lampshade 2 is deformed to significantly block the reflector 12;

[0047] Second station: the inner wall of the soft light cover 2 rebounds slightly to block the reflector 12;

[0048] The third station: the inner wall of the soft light lampshade 2 is pulled away from the reflector 12 .

[0049] Specifically, in the default state, the soft light lampshade 2 is in the second position, at which time the soft light lampshade 2 is not subjected to external force, and only a small part of the inner wall of the soft light lampshade 2 blocks the reflector 12, and the soft light lampshade 2 is illuminated by the light reflected by the reflector 12 to emit soft light for illumination, and the irradiation range of the reflector 12 is not greatly affected. When it is necessary to increase the soft light and reduce the range of direct light, the limiting cover 31 is rotated to move toward the soft light lampshade 2 and switch the soft light lampshade 2 to the first position. At this time, the soft light lampshade 2 is pushed by the limiting cover 31 and deformed toward the central axis of the reflector 12 to block the reflector 12, so as to increase the light irradiated to the soft light lampshade 2, thereby increasing the soft light and reducing the direct light. When soft light is not needed and only direct light is needed, the soft light lampshade 2 is switched to the third position. At this time, the soft light lampshade 2 is Fig.10 As shown, the inner wall of the soft light lampshade 2 is pulled away from the reflector 12 to minimize the light received by the soft light lampshade 2. At this time, the range of the direct light is the largest.

[0050] As an embodiment provided by the present invention, a central column 53 is provided on the light emitting board 51 , and the central column 53 moves along the central axis of the combined cover 1 to pull the soft light lampshade 2 to deform.

[0051] Specifically, a heat conducting plate 52 is provided on the light-emitting board 51, a center column 53 is provided on the heat conducting plate 52, a nut ring 62 is provided on the bottom shell 10, a stud sleeve 61 is provided on the center column 53, the stud sleeve 61 is threadedly connected to the nut ring 62, a wire 511 electrically connected to the LED lamp bead is provided on the light-emitting board 51, the wire 511 passes along the center column 53, and a connecting handle 532 is provided on the stud sleeve 61. When the soft light lampshade 2 needs to be switched to the third position, the connecting handle 532 is rotated to drive the stud sleeve 61 to move along the nut ring 62, so as to drive the light-emitting board 51 to move, so as to pull the soft light lampshade 2 through the reflector 12, so as to pull the soft light lampshade 2 to the third position. Fig.10 Position shown.

[0052] As an embodiment provided by the present invention, a heat dissipation fin group is arranged on the light emitting board 51 , and a deformation groove 22 is opened on the soft light lampshade 2 , and the deformation groove 22 faces the heat dissipation fin group.

[0053] Specifically, the heat dissipation fin group includes a fitted heat conductive plate 52 arranged on the light-emitting panel 51, a heat dissipation bracket 521 is arranged in a circular array on the fitted heat conductive plate 52, and a heat dissipation fin 54 is plugged into the heat dissipation bracket 521. A plurality of deformation grooves 22 are provided in a circular array on the soft light lampshade 2. When the soft light lampshade 2 is in the first working position and approaches the central axis of the reflector 12, the deformation groove 22 expands to guide the airflow into the soft light lampshade 2 to dissipate heat to the heat dissipation fins 54 and the soft light lampshade 2.

[0054] Furthermore, when the soft light lampshade 2 is in the third position, the deformation groove 22 expands and widens as the soft light lampshade 2 is pulled to increase the heat dissipation capacity. It expands in both the first and third positions to dissipate heat while also increasing the deformation capacity of the inner wall of the soft light lampshade 2.

[0055] Furthermore, a plug interface 531 is provided on the central column 53, and the plug interface 531 is clamped between the plurality of heat dissipation brackets 521 for fixation. A connecting card 541 is provided on the heat dissipation fin 54, and the connecting card 541 and the heat dissipation bracket 521 are connected by interference fit.

[0056] As an embodiment provided by the present invention, a limiting cover 31 is further included, and the heat dissipation fin group moves with the light emitting panel 51 to fit the limiting portion 311 on the limiting cover 31 to limit the limiting cover 31 .

[0057] Specifically, an arc groove 542 is provided on the heat dissipation fin 54 of the heat dissipation fin group, and a limiting portion 311 is provided on the inner wall of the limiting cover 31. When the soft light lampshade 2 is switched to the third position, the light-emitting board 51 will move along the central axis of the combination cover 1 and away from the soft light lampshade 2, so that the heat dissipation fin 54 will move and fit the limiting portion 311 for locking, so as to limit the movement of the light-emitting board 51 and avoid excessive pulling on the soft light lampshade 2. At the same time, it is prevented that the limiting cover 31 is accidentally moved when it is in the third position, causing deformation of the soft light lampshade 2.

[0058] As an embodiment provided by the present invention, a vent 312 is provided on the limiting cover 31 , and the soft light cover 2 is driven away from the limiting cover 31 , and a cooling channel is formed therebetween.

[0059] Specifically, when the soft light lampshade 2 switches to the second position, the soft light lampshade 2 rebounds. At this time, there is a cooling channel between the soft light lampshade 2 and the limiting cover 31. Fig.11 As shown in the middle upper figure, at this time, the airflow enters along the cooling channel and moves out from the vent 312, bringing out the heat flow for cooling. When the soft light cover 2 is switched to the third position, the soft light cover 2 will be pulled, so that the cooling channel is expanded, as shown in FIG. Fig.11 As shown in the middle left figure, the cooling efficiency is increased, and when switching to the first station, the cooling channel is closed, as shown in Fig.11 As shown in the middle right figure, at this time, the airflow passes through the deformation groove 22 to dissipate heat from the heat dissipation fins 54.

[0060] As the best embodiment provided by the present invention, a plurality of support plates 41 are arranged in a circular array in the soft light lampshade 2 , a plurality of heat dissipation strips 411 are arranged in a linear array between the support plates 41 , and the support plates 41 are deformed and bent along with the soft light lampshade 2 .

[0061] Specifically, the support plate 41 provides a certain degree of support to the outer wall of the soft light lampshade 2. When the soft light lampshade 2 switches to the first working position, the limiting cover 31 pushes the soft light lampshade 2, driving the outer wall of the soft light lampshade 2, that is, the support plate 41 to partially bend, thereby realizing the movement of the inner wall of the soft light lampshade 2 in the first working position toward the reflective cover 12 to adjust the light. The multiple heat dissipation strips 411 can also dissipate heat for the soft light lampshade 2, thereby sharing the heat inside the soft light lampshade 2.

[0062] Furthermore, a plurality of heat dissipation fins 54 are arranged in a circular array on the light-emitting panel 51. When the heat dissipation strip 411 bends with the support plate 41, the heat dissipation strip 411 will fit into the arc groove 542 on the heat dissipation fin 54, thereby sharing the heat of the soft light lampshade 2 at the first station. At the same time, the heat dissipation strip 411 fitting into the heat dissipation fin 54 will lock and fix the reflector 12 to fix the first station of the soft light lampshade 2 and prevent the movement of the center column 53.

[0063] First, the combined cover 1 is installed on the truss through the connecting frame 1, and the angle is adjusted to drive the central axis of the combined cover 1 toward the exhibits. Then, the combined cover 1 is adjusted according to the venue and exhibits: when an environment where a relatively equal ratio of direct light and soft light is required, the soft light cover 2 in the default state (i.e., the second station) is not restricted, and the soft light and direct light can be evenly irradiated;

[0064] When a larger range of soft light is needed, the rotation limiting cover 31 pushes the soft light cover 2 to switch to the first position, driving the support plate 41 to bend, so that the soft light cover 2 is deformed toward the central axis of the reflector 12 to block the reflector 12, so as to increase the soft light range and reduce the direct light range. At the same time, the heat dissipation strip 411 fits the heat dissipation fins 54 to lock and fix the reflector 12;

[0065] When a larger range of direct light is needed, the soft light cover 2 is restored to the second position, and then the connecting handle 532 is rotated to drive the stud sleeve 61 to move along the nut ring 62 to drive the light-emitting board 51 to move, so as to pull the soft light cover 2 through the reflector 12 to pull the soft light cover 2 to the second position. Fig.10 The position shown in the figure can expand the range of direct light, and at the same time, the heat dissipation fins 54 can move and fit the limiting portion 311 to be locked, so as to limit the movement of the light-emitting panel 51.

[0066] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
