Description

Technical Field

[0001] The present application relates to the field of stage lamps, and in particular to a bottom box pull-out structure of a stage lamp and a stage lamp using the pull-out structure. Background Art

[0002] The stage lighting fixture mainly includes the lighting fixture body and the bottom box. The bottom box integrates the power supply and driver to provide power for the stage lighting fixture and to control the stage lighting fixture. When in use, the stage lighting fixture needs to be installed in the corresponding area, and some stage lighting fixtures will be installed on the ground or in the air through brackets.

[0003] Since stage lighting is a long-term and repetitively used device, in order to extend its service life, it is often necessary to regularly protect and maintain the lighting, and to repair it after a failure. For example, the garbage attached to the surface of the lighting, the stains on the surface of the optical element, the lighting control system, that is, the wiring and program detection of the driver, the power wiring, etc., are used to maintain the stability of the use of stage lighting.

[0004] However, in actual use, since some stage lamps are installed in the air, the entire lamp needs to be dismantled for maintenance and repair when the power supply and driver wiring need to be tested, which makes the maintenance and repair process relatively complicated, and there are certain safety hazards in aerial operations. Therefore, how to maintain aerial stage lamps relatively conveniently is an urgent problem to be solved. Summary of the invention

[0005] In order to relatively conveniently perform maintenance of an aerial stage lighting fixture, the present application provides a bottom box pull-out structure of a stage light and a stage lighting fixture using the pull-out structure.

[0006] In the first aspect, the present application provides a bottom box pull-out structure of a stage light, which adopts the following technical solution:

[0007] A bottom box pull-out structure for a stage light comprises a bottom box, a pull-out assembly, a power module and a control module, wherein the power module and the control module are integrated in the pull-out assembly; the bottom box is formed with an installation chamber; the pull-out assembly comprises a detachable sliding module and a display module arranged on the sliding module, wherein the power module and the control module are slidably connected to the installation chamber via the sliding module, and the display module is used to display information and seal the installation chamber.

[0008] By adopting the above technical solution, when maintenance is needed, it is only necessary to slide the display module, power module and control module out of the installation cavity through the sliding module, and separate them, so that the power module, control module and display module can be maintained and repaired separately, without removing the bottom box and the lamp as a whole, so that later maintenance and repair can be carried out relatively conveniently. At the same time, the installation cavity can be blocked by the display module to reduce the possibility of the power module and the control module being soaked during rain.

[0009] Optionally, the power module and / or the control module is provided with a fan located in the installation chamber.

[0010] By adopting the above technical solution, the fan can make the air inside the installation chamber flow fully, thereby accelerating the diffusion speed of the heat generated by the power module and the control module during operation.

[0011] Optionally, two fans are provided and the gas conveying directions of the two fans are arranged opposite to each other.

[0012] By adopting the above technical solution, the two fans arranged opposite to each other can form a stable convection, thereby reducing the possibility of air circulation in a local area.

[0013] Optionally, the display module includes a display base and a display panel fixed to the display base, the display panel is electrically connected to the power module and the control module, and the display base is fixed to the sliding module and is used to block the installation cavity.

[0014] By adopting the above technical solution, the base is limited to be used as the connection basis of the power module and the control module, and the corresponding information is displayed through the display panel.

[0015] Optionally, a cavity wall of the installation cavity is provided with an air duct connected to the outside, the air duct is provided with two input parts, and the cross-sectional area of ​​the cavity corresponding to the air duct at the intersection of the two input parts is greater than the sum of the cross-sectional areas of the two input parts.

[0016] By adopting the above technical solution, external air can enter the air duct through two input parts and the area used by the air after entering the air duct becomes larger and the flow rate slows down, so that in rainy weather, rainwater carried by the air can be retained in the air duct due to the slowed air flow rate, reducing the possibility of inhaling air and bringing rainwater directly into the installation chamber.

[0017] Optionally, the chamber of the air duct corresponding to the intersection of the two input parts expands laterally along the plane of the cavity wall of the installation cavity to form a buffer portion, and one of the input parts is tilted downward and used for drainage, the air flow resistance input by the input part used for drainage is greater than the air flow resistance of the other input part, and the other input part is used to input air.

[0018] By adopting the above technical solution, air can be introduced through one of the input parts, and rainwater retained in the buffer part can be discharged through the other input part, further reducing the possibility of rainwater entering the installation chamber.

[0019] Optionally, the input part for drainage is connected to the bottom of the buffer part and is provided with a damping structure, wherein the damping structure includes a main channel and a plurality of side channels, wherein the main channel is connected to the bottom of the buffer part, the path of the main channel is a zigzag structure, the two ends of the side channels are respectively connected to two adjacent zigzag corner positions of the main channel, and one end of the side channel toward the buffer part is recessed toward the buffer part to form an arc-shaped path and turns away from the buffer part toward the opening.

[0020] By adopting the above technical solution, when the fan is working, during the inflow of external air, the airflow passing through the main channel will be diverted due to the existence of the secondary flow channel, and since one end of the secondary flow channel facing the buffer portion is arranged away from the opening of the buffer portion, the airflow in the secondary flow channel and the airflow in the main channel will collide with each other, so as to significantly slow down the air flow and increase the resistance to flow toward the buffer portion, so that the air flow resistance input by the input portion for drainage is greater than the air flow resistance of the other input portion, and the existence of the secondary flow channel can balance the air pressure in time during the discharge of rainwater, accelerate the outflow of rainwater, and reduce the possibility of rainwater blocking the main channel.

[0021] Optionally, the two secondary flow channels connected by adjacent bending portions of the main flow channel are respectively located on both sides of the main flow channel.

[0022] By adopting the above technical solution, turbulence can be formed at the intersection of the secondary flow channel and the main flow channel and hinder the air from flowing toward the buffer portion. Moreover, since the two secondary flow channels connected by adjacent bending portions of the main flow channel are respectively located on both sides of the main flow channel, the air flowing toward the buffer portion can be further diverted.

[0023] Optionally, a plurality of condensation plates are arranged in the buffer portion, and the condensation plates are arranged at an inclination and corresponding to the input air input portion.

[0024] By adopting the above technical solution, rainwater carried in the introduced air can fully contact and condense with the condensation plate, and then be discharged after falling toward the bottom of the buffer part through the inclined condensation plate.

[0025] In a second aspect, the present application provides a stage lighting device, which adopts the following technical solution:

[0026] A stage lighting fixture is provided with the above-mentioned bottom box drawer structure.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] When maintenance is needed, just pull the display base to make the power module and the control module detach from the installation chamber, and then disconnect them, so that the power module and the control module can be removed for maintenance and repair, without removing the stage lamp as a whole, so that maintenance and repair can be carried out relatively conveniently, and convection can be formed in the installation chamber through the fan, so as to quickly transfer the heat generated by the power module and the control module to the inner wall of the installation chamber to accelerate the heat dissipation speed BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-8 This application is described in further detail.

[0039] The embodiments of the present application disclose a bottom box pull-out structure of a stage lamp and a stage lamp using the bottom box pull-out structure.

[0040] Example 1

[0041] Embodiment 1 of the present application discloses a bottom box pull-out structure of a stage light

[0042] Reference Figure 2 and Figure 3 The bottom box pull-out structure of the stage light comprises a bottom box 1, a pull-out assembly 2, a power module 3 and a control module 4. The bottom box 1 is used as the installation base of the stage light. The power module 3 and the control module 4 are both located in the bottom box 1 when in use.

[0043] Specifically, an installation chamber 11 is formed inside the bottom box 1, and the installation chamber 11 is set corresponding to a side opening of the bottom box 1, preferably a horizontal opening. The power module 3 and the control module 4 are slidably connected to the inner wall of the installation chamber 11 through the pull-out assembly 2, so that the power module 3 and the control module 4 can be withdrawn from the installation chamber 11 for maintenance. Of course, the power module 3 and the control module 4 can be connected to other power units by sliding plug-in, or after wiring, the power module 3 and the control module 4 can be slid into the installation chamber 11.

[0044] Reference Figure 3 and Figure 4 The pull-out assembly 2 includes a sliding module 21 and a display module 22, and the sliding module 21 can be detachably arranged. That is, the sliding module 21 is arranged one-to-one corresponding to the power module 3 and the control module 4. The sliding module 21 includes a sliding base 211 and a sliding track 212, the sliding track 212 is parallel to the opening direction of the installation chamber 11, and the sliding track 212 is fixed to the inner wall of the installation chamber 11, and is formed with a slide groove 213 for clamping the sliding track 212. The sliding base 211 is a plate-like structure and a connecting portion 214 is bent and formed on one side edge corresponding to the opening of the installation chamber 11. The sliding base 211 slides and is clamped in the slide groove 213. At the same time, the connecting portion 214 is used to connect the display module 22. Among them, the power module 3 and the control module 4 are fixed to the sliding base 211 one-to-one.

[0045] Of course, in other embodiments, the sliding module 21 may also be configured as a detachable damping slide rail.

[0046] Reference Figure 3 and Figure 4 Meanwhile, the display module 22 includes a display base 221 and a display panel 222 fixed to the display base 221 on a side away from the installation chamber 11. The display base 221 is directly or indirectly fixed to the sliding module 21 and is used to block the opening of the installation chamber 11. The display panel 222 is electrically connected to the power module 3 and the control module 4 to display the power and control information of the power module 3. This is a prior art and will not be described in detail here.

[0047] Specifically, the connection part 214 on the sliding base 211 where the control module 4 is located is detachably fixed to the outer wall of the display base 221 facing the installation chamber 11 by bolts; and the connection part 214 on the sliding base 211 where the power module 3 is located is fixed to the display base 221 by a fan 12, so as to dissipate heat and separate the components. At the same time, a fan 12 is fixed inside the installation chamber 11 corresponding to the sliding base 211 where the control module 4 is located, and the two fans 12 are arranged opposite to each other to form convection, so as to dissipate heat for the power module 3 and the control module 4 in the installation chamber 11.

[0048] The implementation principle of Example 1 is as follows: when maintenance is required, it is only necessary to pull the display base 221 so that the power module 3 and the control module 4 can be separated from the installation chamber 11, and then disconnect them, so that the power module 3 and the control module 4 can be removed for maintenance and repair without removing the entire stage lighting fixture, so that maintenance and repair can be carried out relatively conveniently, and convection can be formed in the installation chamber 11 through the fan 12, so as to quickly transfer the heat generated by the power module 3 and the control module 4 to the inner wall of the installation chamber 11 to accelerate the heat dissipation speed.

[0049] Example 2

[0050] Reference Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that the cavity wall of the installation chamber 11 is provided with an air duct 13 connected to the outside to form air flow exchange between the inside and the outside, thereby further optimizing the heat dissipation efficiency.

[0051] The air duct 13 can be disposed on the bottom box 1 or the sliding base 211 . In the second embodiment, the air duct 13 is disposed on the bottom box 1 as an example for description.

[0052] Reference Figure 6 and Figure 7 Specifically, the air duct 13 is arranged at an angle and the top thereof is connected to the position of the fan 12 in the installation chamber 11. Two input parts 131 are formed at the lower part of the air duct 13. The input parts 131 are arranged at an angle and the lower end thereof is connected to the outside. The upper parts of the two input parts 131 intersect and expand to form a buffer part 132. The buffer part 132 is formed by extending the cavity wall toward the circumferential side, so that the cross-sectional area of ​​the cavity corresponding to the air duct 13 at the intersection of the two input parts 131 is greater than the sum of the cross-sectional areas of the two input parts 131, so that the flow velocity of the air introduced by the two input parts 131 when entering the buffer part 132 will be slowed down, so that in the case of rainy weather, the water droplets flowing in with the air can contact the inner wall of the buffer part 132 due to the slowed air flow velocity and be discharged by the bottom input part 131.

[0053] At the same time, in order to further reduce the possibility of air carrying raindrops into the installation chamber, one of the input parts 131 is connected to the middle position of the buffer part 132 after molding and is used to introduce air; the other input part 131 is connected to the bottom of the buffer part 132 and is used to discharge the rainwater condensed in the buffer part 132. The flow resistance of the air in the input part 131 for introducing air toward the buffer part 132 is L1, and the flow resistance of the air in the input part 131 for drainage toward the buffer part 132 is L2, then L1<L2, so as to reduce the possibility of rainwater blocking the input part 131 for drainage and even causing rainwater in the external air to flow back.

[0054] In order to make L1 < L2, a plurality of damping paddles are provided in the input portion 131 of the housing for drainage to increase the air resistance of the air flowing in. Of course, in the third embodiment of the present application, a damping structure is provided in the input portion 131 for drainage to make L1 < L2.

[0055] Reference Figure 6 , Figure 7 and Figure 8 The damping structure includes a main channel 133 and a plurality of secondary channels 134. The main channel 133 is arranged in an inclined manner, and the top of the main channel 133 is connected to the bottom of the buffer portion 132, and the bottom of the main channel 133 is connected to the outside. The extension path of the main channel 133 is a zigzag structure, and each bending portion is provided with a secondary channel 134. The two ends of the secondary channel 134 are respectively connected to the corner positions of two adjacent bending portions of the main channel 133, and the part of the secondary channel 134 facing the end of the main channel 133 connecting to the buffer portion 132 is concave toward the buffer portion 132 in an arc shape, and the opening of the secondary channel 134 facing the end of the buffer portion 132 is arranged toward the end of the main channel 133 connecting to the outside, so that when air flows in from the outside, the air diverted to the secondary channel 134 will reversely impact the air in the main channel 133 and form a vortex.

[0056] Specifically, the end of the secondary flow channel 134 facing the outside is a, and the bend portion of the main flow channel 133 adjacent to the side of the secondary flow channel 134 facing the outside is b, then a is parallel to b and located on the same extension path, so that when the air flows toward the buffer portion 132 through the main flow channel 133, most of the air will be directly diverted to the secondary flow channel 134 and fully reversely impact the airflow in the main flow channel 133, so as to achieve the purpose of sufficient damping. At the same time, the two secondary flow channels 134 connected by the adjacent bends of the main flow channel 133 are respectively located on both sides of the main flow channel 133, so that the vortex formed by the bend corner of the main flow channel 133 can further hinder the air from flowing from the outside through the main flow channel 133 into the buffer portion 132, so that the air entering the buffer portion 132 flows in through the input portion 131 for introducing air. At the same time, due to the existence of the secondary flow channel 134, when rainwater flows out, the main flow channel 133 is used for drainage, and the secondary flow channel 134 is used for balancing air pressure to reduce the resistance of rainwater discharge.

[0057] Reference Figure 6 and Figure 7 In addition, a plurality of condensation plates 135 are fixedly connected in the buffer part 132. The plurality of condensation plates 135 are parallel to each other and vertically distributed, and there is a clearance fit between the condensation plates 135 and the input end of the input part 131 for introducing air, and there is also a clearance fit between the condensation plates 135 and the inner wall of the input end of the input part 131 for introducing air in the buffer part 132. The condensation plates 135 are arranged in an inclined manner and corresponding to the input air input part 131, so that the input air can fully contact the condensation plates 135 and the rainwater carried can be fully condensed, and then fall into the bottom of the buffer part 132 for easy discharge, thereby fully reducing the possibility that the rainwater is carried into the buffer part 132 by the air flow and makes the power module 3 and the control module 4 wet.

[0058] Finally, in order to facilitate processing and installation, the buffer portion 132 and the air duct 13 are arranged with an opening structure facing away from the installation chamber 11, and the buffer portion 132 and the air duct 13 are covered with a cover 14 away from the installation chamber 11. The cover 14 is fixed to the inner wall of the buffer portion 132 and the air duct 13 by bolts, and a plurality of input portions 131 for introducing air are provided and located on the cover 14.

[0059] The implementation principle of the second embodiment is as follows: when the fan 12 is working, the external air will be introduced through the buffer part 132, and the air introduced into the buffer part 132 can only be introduced through the two input parts 131, and because the air inputted by the input part 131 for introducing air will directly contact the condensation plate 135, and the cooperation of the main flow channel 133 and the secondary flow channel 134 in the input part 131 for drainage will make the air resistance of the input part 131 for drainage much greater than that of the input part 131 for introducing air, so that the air at the bottom of the buffer part 132 connected to the air is The input portion 131 can discharge the water condensed on the condensation plate 135 in time, and since the space becomes larger after the air enters the buffer portion 132, the flow rate will be slowed down, further reducing the possibility of rainwater being carried into the installation chamber 11 by the air, so that the water in the air can be discharged in time through the input portion 131 at the bottom; and, the cooling effect on the power module 3 and the control module 4 in the installation chamber 11 is optimized, reducing the possibility of increased failure rate due to the power module 3 and the control module 4 being installed in the installation chamber 11 by pulling.

[0061] The present application also discloses a stage lighting fixture. Figure 1 The stage lighting fixture includes a lamp 5 and is provided with the aforementioned stage lighting bottom box pull-out structure. The lamp 5 is installed on the bottom box 1 through a frame.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
