Tray lamp

Abstract

In the field of lighting fixtures, we provide tray lamps that can reduce the burden of maintenance work. [Solution] The system includes a tray 100, a light-emitting assembly 200, and a drive module 300. The tray is attached to a mounting structure, the light-emitting assembly is attached to the tray and emits light from the first side of the tray, and the drive module is electrically connected to the light-emitting assembly and supplies power to the light-emitting assembly. After the tray is attached to the mounting structure, the drive module is located on the second side opposite the first side, and an opening 101 is provided in the tray, which allows the drive module to be removed from the second side and placed on the first side, and then moved back from the first side to the second side. By providing an opening in the tray, the problem of complicated maintenance work, which would otherwise require removing the tray from the building's mounting structure when performing maintenance on the drive module, is solved.

Description

Technical Field

[0001] This application belongs to the field of lighting fixtures, and specifically relates to a trailer lamp.

Background Art

[0002] A trailer lamp includes a flat disk-shaped tray. When installing the trailer lamp on a building, the tray, which is the main structure of the lamp, is fixed to the mounting structure of the building such as a suspended ceiling, a keel, or a wall. In addition to the tray, the trailer lamp further includes a light-emitting assembly and a driving module. The light-emitting assembly is installed inside the tray and emits light to the first side of the trailer lamp, enabling the lighting function of the lamp to be realized. The driving module is electrically connected to the light-emitting assembly and supplies power to the light-emitting assembly.

[0003] However, after the trailer lamp is installed, the driving module is located on the second side opposite to the above-mentioned first side. For example, when the trailer lamp is installed on the suspended ceiling in an embedded manner, the lower side of the suspended ceiling is the first side, and the upper side of the suspended ceiling is the second side. After the trailer lamp is installed, the driving module is located above the suspended ceiling. When maintenance of the driving module is required, such as inspection or replacement, the tray must first be removed from the suspended ceiling. As a result, the maintenance work of the driving module becomes complicated and inconvenient, and the usability of the lamp is impaired.

Summary of the Invention

Problems to be Solved by the Invention

[0004] This application aims to provide a trailer lamp to solve the problem that the maintenance work of the driving module of the conventional trailer lamp is complicated and inconvenient because the tray must first be removed from the mounting structure of the building when maintenance is performed.

Means for Solving the Problems

[0005] To achieve the above objective, this application provides a tray lamp comprising a tray, a light-emitting assembly, and a drive module. After the lamp is put into use, the tray is attached to a mounting structure. The light-emitting assembly is attached to the tray and emits light on the first side of the tray to realize the illumination function of the lamp. The drive module is located on the second side, which is opposite the first side. The drive module is electrically connected to the light-emitting assembly and supplies power to the light-emitting assembly.

[0006] Compared to conventional technology, the lamp tray provided by this invention is provided with an opening that allows the drive module to be removed from the second side, placed on the first side, and then moved from the first side to the second side. As a result, the second side, which was originally an inaccessible space, becomes a maintenance space, and the drive module can be inspected and / or replaced without removing the tray, improving the convenience and efficiency of lamp maintenance.

[0007] In one possible embodiment, the drive module is provided with a handle structure. The handle structure allows the drive module to be moved or placed down without the use of tools.

[0008] In one possible embodiment, the handle structure is detachably fixed and connected to the tray, so that after the lamp is installed in the building, the drive module is fixed relative to the tray and the drive module is prevented from accidentally shifting.

[0009] In one possible embodiment, the handle structure is provided with a gripping portion for gripping with the fingers.

[0010] In one possible embodiment, the handle structure is formed from a multi-stage bent plate, which is easy to process and manufacture, while also allowing for easy control of the position and orientation of the drive module by adjusting the number and angle of bends.

[0011] In one possible embodiment, the shape of the opening provided in the tray is rectangular, and since the rectangle is a regular shape, it is easy to process and manufacture.

[0012] In one possible embodiment, the opening in the tray is obscured by the light-emitting assembly and is not visible when viewed from the first side of the tray. This prevents the opening from having an adverse effect on the appearance and / or emission effect of the lamp.

[0013] In one possible embodiment, the tray may be mounted inside the mounting structure in a recessed manner, or it may be mounted outside the mounting structure in a non-recessed manner.

[0014] In one possible embodiment, the light-emitting assembly is detachably connected to the tray and electrically connected to the drive module in a push-in manner via a connecting component. In this embodiment, the tray, light-emitting assembly, and drive module are each relatively independent modules, and such a modular structure is advantageous not only for allowing each module to be assembled in parallel but also for reducing inventory for the vendor.

[0015] In one possible embodiment, the light-emitting assembly is connected to the tray through an elastic assembly. This embodiment provides a connection structure for the light-emitting assembly to the tray. Optionally, the elastic assembly includes a torsion spring structure. [Brief explanation of the drawing]

[0020] In one embodiment, referring to Figures 1 to 4, the tray lamp provided by the present application includes a tray 100, a light-emitting assembly 200, and a drive module 300. The tray 100 is mounted on a mounting structure 400 and is provided with an opening 101. The light-emitting assembly 200 is mounted on the tray 100 and emits light on a first side 100a of the tray 100 to provide illumination for the lamp. The drive module 300 is electrically connected to the light-emitting assembly 200 and supplies power to the light-emitting assembly 200. After the lamp is put into use, the tray 100 is mounted on the mounting structure 400, the drive module 300 is located on a second side 100b opposite the first side 100a, and the opening 101 allows the drive module 300 to be removed from the second side 100b and placed on the first side 100a, and then moved from the first side 100a to the second side 100b.

[0021] If it is necessary to inspect or replace the drive module 300 of the lamp provided by this application, the drive module can be taken out or placed in through the opening 101 (including taking the drive module out from the second side 100b and placing it on the first side 100a, and moving the drive module from the first side 100a to the second side 100b), without having to remove the tray 100.

[0022] Compared to conventional technology, the lamp provided by this invention, by providing an opening 101 in the tray 100, transforms the previously inaccessible second side 100b into a maintenance space, allowing inspection and / or replacement of the drive module 300 without removing the tray 100, thereby improving the convenience and efficiency of lamp maintenance.

[0023] Users of the lamps provided by this invention can easily replace the drive module (compared to conventional technology) by following the instructions in the user manual, even without extensive expertise in lamps and electrical work. Furthermore, these characteristics are highly practical when there are technological upgrades to the lamps, allowing the lamp maintenanceer or user themselves to quickly replace the drive module and complete the lamp upgrade.

[0024] Optionally, the lamps provided by this application may be used in settings where maintenance is frequent, such as commercial facility lighting and office lighting.

[0025] In this embodiment, the drive module 300 can be taken out and placed using the hand and / or via a tool.

[0026] Figures 5a to 5f illustrate the process of moving the drive module 300 from the first side 100a to the second side 100b via an auxiliary structure (handle structure 310) using a hand (not shown). It is easy to understand that the process of removing the drive module 300 from the second side 100b and placing it on the first side 100a is the reverse.

[0027] In the examples shown in Figures 5a to 5f, the light-emitting assembly 200 obstructs the opening 101, so it is necessary to remove the light-emitting assembly 200 from the tray 100 before placing the drive module 300. Therefore, the light-emitting assembly 200 is not shown in the figures. The process of placing the drive module 300 will be explained below by describing each schematic diagram. In Figure 5a, the drive module 300, to which the handle structure 310 is attached, is brought closer to the tray 100. In Figure 5b, the orientation of the drive module 300 is adjusted to align with the opening 101 in the tray 100, and in the figure, the dashed line at the opening 101 represents the width boundary of the opening 101. In Figure 5c, the drive module 300 is passed through the opening 101. In Figure 5d, the drive module 300 has completely passed through the opening 101 and reached the second side 100b. In Figure 5e, the attitude of the drive module 300 is adjusted while holding the handle structure 310 by hand. In Figure 5f, the drive module 300 is placed in a pre-set position.

[0028] In this embodiment, in addition to the lamp structure shown in Figures 1 to 4, the tray may have other shapes, and the opening may be provided at other positions on the tray.

[0029] Referencing Figure 6, optionally, the opening 101' is located at a different position on the tray 100' compared to the structures shown in Figures 1 to 4. In the figure, the dashed line at the opening 101' represents the boundary of the opening 101'. In this modified structure, since the opening 101' is not obstructed by the light-emitting assembly 200, the drive module (not shown) can be taken out or placed in without removing the light-emitting assembly 200.

[0030] Optionally, in the modified structure shown in Figure 6, the dimensions of the opening 101' can be set to allow a hand to pass through, thereby enabling the drive module to be taken out and placed using only hands, without the need for tools and auxiliary structures. When the drive module is located on the second side 100b, it can be placed on the left side of the opening 101', on top of the tray 100', or on the right side of the opening 101', on the mounting structure 400.

[0031] It is easy for those skilled in the art to understand that, in this invention, the length of the electrical connection wire between the drive module and the light-emitting assembly can be adaptively set so that the drive module can move freely over a sufficiently wide range. Furthermore, the end of the connection wire connected to the drive module can be connected to the drive module in a push-in manner using a terminal block, so that the drive module can be easily separated from the connection wire.

[0032] Regarding the modified structure shown in Figure 6, after the lamp is installed in the building, the opening 101' can be observed from the first side 100a. To prevent the opening 101' from potentially having an adverse effect on the appearance or emission effect of the lamp, a removable cover can optionally be attached to the opening 101' to close the opening 101' when the lamp is in normal use.

[0033] Optionally, referring to Figure 7, a tray structure different from the structures shown in Figures 1 to 4 is shown. In Figure 7, the tray 100'' is generally plate-shaped, and an opening 101'' is provided in the center of the tray 100''.

[0034] In this application, the tray 100 generally has a flat, disc-shaped structure; that is, referring to Figure 2, the dimension T along the thickness direction of the tray 100 is smaller than the dimension H perpendicular to the thickness direction.

[0035] Specifically, referring to Figure 2, in this application, the first side 100a and the second side 100b are separated by the ejection-side end face 100c of the tray 100, with the ejection side of the ejection-side end face 100c being the first side 100a and the other side being the second side 100b.

[0036] In one embodiment, referring to Figure 8, a handle structure 310 is connected to a drive module 300, and the handle structure 310 has a first end 310a and a second end 310b, with the first end 310a of the handle structure 310 being connected to the drive module 300. Referring to Figure 9, when the drive module 300 is located on the second side 100b (i.e., when the tray 100 is attached to the mounting structure 400 and the lamp is ready for use), the second end 310b of the handle structure 310 is positioned to be touched from the first side 100a, thereby allowing the drive module 300 to be picked up and placed down by hand without the use of tools, thus fulfilling the purpose of picking up and placing the drive module without tools.

[0037] Furthermore, for the lamp structures shown in Figures 1 to 4, it is necessary to include the light-emitting assembly 200 so that the second end 310b of the handle structure 310 can be touched from the first side 100a. For the lamp structure shown in Figure 6, it is not necessary to include the light-emitting assembly 200.

[0038] Specifically, in this embodiment, "the second end 310b of the handle structure 310 is positioned to be touched from the first side 100a" means that the second end 310b of the handle structure 310 can be touched from the first side 100a without removing the tray 100 from the mounting structure 400.

[0039] In this embodiment, after the drive module 300 is placed in a predetermined position on the second side 100b, the second end 310b of the handle structure 310 may or may not be in contact with the tray 100.

[0040] Optionally, referring to Figure 9, the second end 310b of the handle structure 310 is in contact with and detachably fixed to the tray 100.

[0041] The second end 310b is fixedly connected to the tray 100 to ensure that the drive module 300 will not be displaced by the shaking of the lamp, even in extreme situations such as an earthquake, and that the drive module 300 will remain in a preset position. The second end 310b is detachably connected to the tray 100 to ensure that the drive module 300 can be conveniently removed from the second side 100b and placed on the first side 100a.

[0042] Optionally, referring to Figure 9, the second end 310b of the handle structure 310 can be removably secured and connected to the tray 100 using a hand screw 320. If it is necessary to remove the drive module 300 from the second side 100b and place it on the first side 100a, the hand screw 320 can be loosened first, and then the drive module can be removed in the reverse order of the process shown in Figures 5a to 5f. After the drive module 300 has been placed from the first side 100a to the second side 100b, the hand screw 320 can be passed through the handle structure 310 and screwed into the tray 100 to secure the drive module 300.

[0043] In addition to using the hand-tightened screw 320, the connection of the second end 310b of the handle structure 310 to the tray 100 can also be achieved by another structure. Optionally, the second end 310b of the handle structure 310 can be connected to the tray 100 through the structures shown in Figures 10 and 11.

[0044] As shown in Figure 11, a connecting plate 103 can be provided on the tray 100, and a slot 104 is formed between the connecting plate 103 and the tray 100. Figure 11 shows the state when the drive module 300 is positioned on the second side 100b and is about to reach a preset position. At this time, by moving the handle structure 310 to the right in the direction indicated by the arrow in the figure and inserting the insertion portion 315' of the handle structure 310 into the slot 104, the connection of the second end 310b of the handle structure 310 to the tray 100 can be achieved.

[0045] When removing the drive module 300 from the second side 100b, the insertion portion 315' is pulled out of the slot 104 in the opposite direction to the direction indicated by the arrow, and then the drive module 300 can be removed and placed on the first side 100a in the reverse of the process shown in Figures 5a to 5f. Referring to Figure 10, when pulling out the insertion portion 315' from the slot 104, the drive module 300 needs to be moved to the left in parallel, and the drive module 300, which is placed on an inclined surface, cannot be moved in parallel in the normal way. Therefore, in the structure shown in Figure 10, when pulling out the insertion portion 315' from the slot 104, the handle structure 310 undergoes some degree of elastic deformation. By setting the depth to which the insertion portion 315' is inserted into the slot 104 and controlling the magnitude of this elastic deformation, the elastic deformation can be kept within an acceptable range.

[0046] Optionally, referring to Figure 12, the second end 310b of the handle structure 310 does not have to contact the tray 100, in which case the tray 100 may be provided with a limiting structure 102 so as to hold the drive module 300 in a preset position. The limiting structure 102 may be a stop block or several limiting plates, these limiting plates defining limiting grooves that conform to the shape of the drive module 300.

[0047] In one embodiment, as shown in Figures 8 to 12, gripping portions 316 and 316' for gripping with the fingers are provided at the second end 310b of the handle structure 310. By providing the gripping portions 316 and 316', the hand can hold the handle structure 310 more conveniently and stably, further improving the convenience when taking out or placing the drive module. In general, by using the handle structure 310, the task of taking out or placing the drive module can be completed with one hand.

[0048] Referencing Figures 9 and 12 (optionally), the gripping portion 316 is generally V-shaped.

[0049] Referencing Figure 11, optionally, the gripping portion 316' is arc-shaped.

[0050] It is easy to understand that the gripping part may have other shapes. Any shape of the gripping part that can be obtained without performing an inventive step is included within the scope of protection of this application.

[0051] After the drive module 300 is optionally placed in a preset position on the second side 100b, the distance between the gripping portion and the tray 100 is 5 to 20 mm.

[0052] Optionally, the tensile force that the gripping part can withstand is greater than 50N.

[0053] In one embodiment, referring to Figure 8, the handle structure 310 is formed by a multi-stage bent plate. This structure is easy to manufacture and leads to cost reduction, while the relative positions of the first end 310a and the second end 310b of the handle structure 310 are easily adjustable. This helps to adapt to various usage scenarios, and by changing the number of bends (stages) and the bending angle, the drive module can be easily positioned in different pre-set positions or maintain different pre-set orientations in various usage scenarios.

[0054] Referencing Figure 8, optionally, the handle structure 310 is bent into six sections, and by bending it into six sections, a connecting section 311, a first intermediate section 312, a second intermediate section 313, a third intermediate section 314, a contact section 315, and a gripping section 316 are formed.

[0055] Referring to Figure 8, the first end 310a of the handle structure 310 is formed at the connection portion 311 and is fixedly connected to the drive module 300. The angle between the connection portion 311 and the first intermediate portion 312 is greater than 90°. Referring to Figure 9, after the drive module 300 is placed in a predetermined position, the first intermediate portion 312 is parallel to the mounting structure 400.

[0056] The angle between the second intermediate section 313 and the first intermediate section 312 is approximately equal to 90°. Referring to Figure 9, the second intermediate section 313 passes through the opening 101 along the thickness direction of the lamp.

[0057] The angle between the third intermediate section 314 and the second intermediate section 313 is approximately equal to 90°. Referring to Figure 9, the third intermediate section 314 has the effect of blocking the opening, which can prevent dust falling from above from entering the inside of the lamp to some extent.

[0058] The third intermediate portion 314 and the contact portion 315 have a small difference in height, forming a stepped structure. The contact portion 315 is in contact with the tray 100. The gripping portion 316 is grasped by the fingers. Optionally, referring to Figure 8, the lengths of the contact portion 315 and the gripping portion 316 are equal and shorter than the lengths of the other parts.

[0059] In one embodiment, referring to Figure 1, the shape of the opening 101 provided in the tray 100 is rectangular. The rectangular opening 101 has a regular shape, is easy to process, and leads to a reduction in processing costs.

[0060] Optionally, the opening 101 is configured such that there is a gap of 1 to 5 mm between the edge of the opening 101 and the drive module and handle structure in order to ensure that the drive module and handle structure can pass through the opening 101 smoothly.

[0061] In one embodiment, referring to Figure 4, after the lamp is installed in the building, the opening 101 provided in the tray 100 is obscured by the light-emitting assembly 200 and is not visible when viewed from the first side 100a. This prevents the opening 101 and / or the handle structure 310 from having an adverse effect on the appearance and / or emission effect of the lamp.

[0062] Referencing optionally Figures 1 and 4, the opening 101 is provided on the back of the tray 100, and near the edge of the back.

[0063] The tray lamp provided by this invention can be installed inside the building's mounting structure by being embedded, or it can be installed outside the mounting structure in a non-embedded manner.

[0064] In one embodiment, referring to Figure 2, the tray 100 is mounted inside the mounting structure 400 in a recessed manner. After the lamp is installed, the output end face 100c of the tray 100 is flush with the mounting structure 400, and only the output side of the lamp is visible, with the rest of the lamp essentially hidden inside the mounting structure 400.

[0065] In one embodiment of this design, the tray can employ the following structure. Referring to Figures 13 and 14, the tray 100 has a back portion 110 and two inclined portions 120 provided at an angle to the back portion 110, with the two inclined portions 120 provided symmetrically on opposing sides of the back portion 110. Referring to Figures 2 and 4, when the drive module 300 is located on the second side 100b, the drive module 300 is placed on one of the inclined portions 120. The opening 101 is provided on the back portion 110 of the tray 100 and near the inclined portion 120 where the drive module 300 is located.

[0066] In this embodiment, the process of moving the drive module 300 between the first side 100a and the second side 100b is shown in Figures 5a to 5f.

[0067] Optionally, referring to Figures 13 and 14, the tray 100 may further include two enclosures 130, the two enclosures 130, the two inclined sections 120 and the back section 110 together define a mounting space, in which the light-emitting assembly is mounted.

[0068] In one embodiment, referring to Figure 25, the tray lamp provided by the present application is mounted to a mounting structure 400' in a non-recessed manner. After the lamp is mounted, there is a certain distance between the exit-side end face 100'''c of the tray 100''' and the mounting structure 400' (the size of which is equal to the thickness of the lamp), and the lamp is visible when observed from the first side 100'''a.

[0069] In one embodiment of this design, the tray can adopt the following structure. Referring to Figures 21 to 27, the tray 100''' has a back portion 110' and two inclined portions 120' provided at an angle to the back portion 110', with the two inclined portions 120' being provided symmetrically on opposite sides of the back portion 110'. A vertical portion 110'a is provided between the inclined portion 120' and the back portion 110', and the vertical portion 110'a extends substantially perpendicular to the back portion 110'. An opening 101''' is provided on one of the two vertical portions 110'a.

[0070] Referring to Figure 23, the tray 100''' further includes two inner enclosures 131, and the two inner enclosures 131, two inclined sections 120', two vertical sections 110'a and the back section 110' together define the space for mounting the light-emitting assembly 200. Referring to Figure 22, the tray 100''' further includes four outer enclosures 132.

[0071] Referring to Figure 27, after the tray lamp is installed, the upper end surface of the outer enclosure 132 is approximately flush with the mounting structure 400', and the lower end surface is approximately flush with the emission surface of the light-emitting assembly 200. The drive module 300 is placed in the housing space 132a, which is defined by one outer enclosure 132, an inclined portion 120' adjacent to the outer enclosure 132, and a vertical portion facing the outer enclosure 132 with an opening 101'''.

[0072] In Figure 27, the lower left corner of the drive module 300 is supported by the upper edge of the inclined portion 120', and the handle structure 310' is removably fixed and connected to the back of the tray by a hand-tightened screw 320', allowing the drive module 300 to be stably held in the illustrated position.

[0073] Figures 28a to 28d show the process of moving the drive module 300 from the first side 100'''a into the housing space 132a located on the second side 100'''b. Similar to Figures 5a to 5f, the light-emitting assembly 200 is not shown in Figures 28a to 28d, and in the figures, the dashed line at the opening 101''' represents the width boundary of the opening 101'''.

[0074] The process of installing the drive module 300 of this embodiment will be explained below by describing each schematic diagram. In Figure 28a, the drive module 300, to which the handle structure 310' is attached, is brought closer to the tray 100'''. In Figure 28b, the top surfaces of the handle structure 310' and the drive module 300 are attached to the back of the tray 100''', and the drive module 300 is aligned with the opening 101''''. In Figure 28c, the drive module 300 is moved to the right and passed through the opening 101'''. In Figure 28d, the drive module 300 has passed completely through the opening 101'''' and reached the preset position. The handle structure 310' is secured and connected to the back of the tray 100'''' using a hand-tightened screw 320'.

[0075] Optionally, in this embodiment, the handle structure can be the structure shown in Figure 24. In Figure 24, the handle structure 310' is formed by a multi-stage bent plate and has a connecting portion 311', a first intermediate portion 312', a second intermediate portion 313', a third intermediate portion 314', a contact portion 315'', and a gripping portion 316''.

[0076] The first end 310'a of the handle structure 310' is formed at the connection portion 311' and is fixedly connected to the drive module 300. Optionally, after the drive module 300 is placed in a pre-set position, the connection portion 311' is approximately parallel to the mounting structure 400', and the drive module 300 is fixed to the upper surface of the connection portion 311'.

[0077] The first intermediate section 312' is substantially perpendicular to the connecting section 311', the second intermediate section 313' is substantially perpendicular to the first intermediate section 312', and the third intermediate section 314' is substantially perpendicular to the second intermediate section 313'. A cable insertion hole 314'a can be provided in the third intermediate section 314' for passing an electrical connection wire, which electrically connects the drive module 300 and the light-emitting assembly 200.

[0078] The contact portion 315'' is approximately perpendicular to the third intermediate portion 314', and the contact portion 315'' contacts the back of the tray 100'''. Optionally, a transition portion 315''a is formed on the contact portion 315'', the length of which is less than the length of the contact portion 315''.

[0079] The gripping portion 316'' is formed in the transition portion 315''a, and their lengths are equal.

[0080] In one embodiment, the light-emitting assembly is detachably connected to the tray and electrically connected to the drive module in a push-in manner via a connecting component.

[0081] This embodiment provides a modularized lamp in which the lamp's light-emitting assembly, tray, and drive module are all detachably connected to each other, making each a relatively independent module. When there is an upgrade to the lamp involving optoelectronics, the lamp upgrade can be achieved simply by replacing the light-emitting assembly and / or drive module, eliminating the need to replace the tray, thus saving on the cost of lamp upgrades.

[0082] Furthermore, the modular design allows for the simultaneous assembly of the light-emitting assembly, drive module, and tray, leading to improved production efficiency. For distributors, only the main modules (i.e., the light-emitting assembly and drive module) need to be stocked, resulting in a reduction in the number of SKUs (Stock Keeping Units) and lower storage costs.

[0083] The light-emitting assembly and the drive module can be electrically connected in a push-in manner through a connecting component. Optionally, the connecting component may be a quick-connect terminal, a plug-in component, or the like.

[0084] Optionally, the electrical connection structure between the light-emitting assembly and the drive module can be configured as follows: The drive module is provided with a first connection wire and a second connection wire, with the drive module connected to one end of the first connection wire and the first end of the connecting component at the other end. A third connection wire is provided, with the light-emitting assembly connected to one end of the third connection wire and the second end of the connecting component at the other end. The connection between the first and second ends of the connecting component realizes the electrical connection between the light-emitting assembly and the drive module. Referring to Figure 8, a cable insertion hole 314a for passing the first connection wire can be provided in the third intermediate portion 314 of the handle structure 310.

[0085] The second connection line is used to connect to the power supply for the lamp, which is, for example, an AC power supply provided by the urban power grid. Optionally, a drive module is connected to one end of the second connection line, and the other end is connected to the power terminal 140 provided on the tray 100 (see Figure 14). The power terminal 140 is connected to the power supply and provides power to the lamp.

[0086] In one embodiment, the light-emitting assembly 200 is connected to the tray 100 through an elastic assembly. Referring to Figures 14 to 18, the elastic assembly includes two elastic components 250 and two connecting components 150. Optionally, the elastic components 250 are fixed to and symmetrically positioned on the upper surface of the light-emitting assembly 200. The connecting components 150 are fixed to and symmetrically positioned on the bottom surface of the back portion 110 of the tray 100.

[0087] Each elastic component 250 has a torsion spring portion 251 and a rotating rod 252 extending from the torsion spring portion 251. The torsion spring portion 251 and the rotating rod 252 are generally an integral structure, and the rotating rod 252 can rotate around the axis of the torsion spring portion 251. When the rotating rod 252 is moved by an external force and rotates, the torsion spring portion 251 undergoes elastic deformation, and this elastic deformation generates a torque in the opposite direction to the rotating rod 252, so that when the external force is removed, the rotating rod 252 rotates in the opposite direction.

[0088] Two connecting parts 150 are connected to two elastic parts 250 in a one-to-one correspondence, and each connecting part 150 has a constraint hole 151a formed in it. Referring to Figure 20, when the rotating rod 252 is inserted into the constraint hole 151a, the torque M generated by the torsion spring part 251 holds the rotating rod 252 inside the constraint hole 151a, the rotating rod 252 is placed on the lower wall of the constraint hole 151a, the wall of the constraint hole 151a generates a supporting force F on the rotating rod 252, and the elastic part 250 is fixed relative to the connecting part 150. As a result the light-emitting assembly 200 is fixed relative to the tray 100, and the mounting of the light-emitting assembly 200 is achieved.

[0089] Referencing optionally to Figure 15, the connecting component 150 includes a constraint component 151 and a guide component 152. A constraint hole 151a is formed in the constraint component 151. The guide component 152 has a guide surface 152a that guides the movement of the free end of the rotating rod 252 so as to position the rotating rod 252 at a predetermined position and / or cause a predetermined deformation. Referring to Figure 20, the guide surface 152a can also constrain the rotating rod 252, which is advantageous for the rotating rod 252 to press against the wall of the constraint hole 151a, thereby stably holding the rotating rod 252 within the constraint hole 151a.

[0090] Optionally, referring to Figure 18, the rotating rod 252 includes two main rods extending from the torsion spring section 251, the free ends of the two main rods connected through a cross rod.

[0091] Optionally, referring to Figures 16 and 17, the elastic component 250 is provided on the heat dissipation plate 240 of the light-emitting assembly 200.

[0092] Optionally, two mounting bases 260 are provided on the heat dissipation plate 240, and elastic components 250 are attached to the mounting bases 260.

[0093] Optionally, the light-emitting assembly 200 further includes a lampshade 210, two side plates 220, and a light source board 230, in addition to the heat sink plate 240. The light source board 230 and the heat sink plate 240 are inserted into the top of the lampshade 210. The two side plates 220 are connected to both sides of the lampshade 210 and, together with the lampshade 210, define the space for housing the light-emitting device.

[0094] The light-emitting device may be a light-emitting diode (LED), and is provided on the light source board 230 to form a light source and realize illumination by lamp.

[0095] Figures 19a to 19g illustrate the mounting process for attaching the light-emitting assembly 200 to the tray 100 using the elastic assembly provided in this embodiment, as follows: In Figure 19a, the left hand (not shown) supports the light-emitting assembly 200 and moves it closer to the tray 100, while the right hand (not shown) twists the rotating rod 252 of the elastic component on the left side to overcome the torque of the torsion spring and raise it to a certain angle. In Figure 19b, the light-emitting assembly 200 is lifted diagonally so that the free end of the rotating rod 252 of the left elastic component is inserted into the constraint hole of the left connecting component. In Figure 19c, the light-emitting assembly 200 is lifted, bringing the elastic component on the right closer to the connecting component on the right. In Figure 19d, the left hand supports the light-emitting assembly 200 while the right hand twists the rotating rod 252 of the elastic component on the right side, overcoming the torque of the torsion spring and raising it to a certain angle. In Figure 19e, the light-emitting assembly 200 is lifted, and the free end of the rotating rod 252 of the elastic component on the right is inserted into the constraint hole of the connecting component on the right. At this point, the free ends of the rotating rods 252 of both elastic components are inside the constraint holes of the connecting component. In Figure 19f, the light-emitting assembly 200 is lifted with both hands and its position is adjusted so that the light-emitting assembly 200 moves along the guide structure provided on the tray 100 to the back surface 110 of the tray 100. In Figure 19g, the light-emitting assembly 200 reaches a predetermined position and is stopped by a stopper structure provided on the tray 100. At this time, referring to Figure 20, the rotating rods 252 of the two elastic components are in the predetermined position, and the wall portion of the constraint hole 151a of the connecting component supports the rotating rods 252, fixing the light-emitting assembly 200 to the tray 100 and realizing the mounting of the light-emitting assembly 200.

[0096] In the state shown in Figure 19b, the drive module can be electrically connected (including the connection of the drive module to the light-emitting assembly and the connection of the drive module to the power terminal 140). To free the left hand that is holding up the light-emitting assembly 200 and to use it for connecting the terminal block, optionally, referring to Figures 14 and 16, a first mounting component 160 can be provided on the tray 100 and a second mounting component 270 can be provided on the light-emitting assembly 200.

[0097] A suspension rope is attached to the first hanging component 160, and a hook is attached to the lower end of the suspension rope. The second hanging component 270 is connected to the hook, allowing the light-emitting assembly 200 to be hung on the tray 100 with both hands free. Both hanging components are positioned close to the left side of the lamp. Referring to Figure 19b, when both hands are free, the left end of the light-emitting assembly 200 lifts up and hits the inner wall of the tray 100, while the right end lowers, increasing the distance from the tray 100 and creating space to work with both hands. With both hands in this workspace, the drive module can be connected.

[0098] When removing the light-emitting assembly 200, an external force is applied to the light-emitting assembly 200, moving it away from the back surface 110 of the tray 100, causing the two rotating rods 252 to overcome the torque of the torsion spring and begin to rotate (at the same time, elastic deformation may occur depending on the shape of the rotating rods 252), and simultaneously to escape from the constraint holes 151a. As the distance the light-emitting assembly 200 moves increases, the two rotating rods 252 eventually escape completely from the two constraint holes 151a, and the removal of the light-emitting assembly 200 is achieved.

[0099] The foregoing describes only preferred embodiments of the present application and is not intended to limit the scope of protection. Any amendments, equivalent substitutions, or improvements made without departing from the intent and principles of the present application are also included within the scope of protection.
