Description

Technical Field

[0001] This utility model relates to a lamp. Background Technology

[0002] Lighting fixtures, such as tri-proof lights, emergency lights, and ceiling lights, generally include a lamp housing and a lamp panel assembly housed within the housing. The lamp housing consists of an upper shell and a light-transmitting lampshade. The bottom of the upper shell is open, while the top of the light-transmitting lampshade is open. The two are fastened together to form a cavity for housing the lamp panel assembly. The lamp panel assembly generally includes a support plate and a light source mounted on the bottom of the support plate.

[0003] For example, the Chinese invention patent application CN202220550851.3 (publication number CN217302700U) discloses a "novel tri-proof lamp", which includes a lamp base shell, a light source carrier plate installed in the lamp base shell, and a lamp cover locked to the lamp base shell by a latch; one side of the light source carrier plate is hinged to the lamp base shell by a rotating connector, and the other side of the light source carrier plate is fastened and positioned to the lamp base shell by a snap fastener. The rotating connector includes a base provided on the side wall of the lamp base shell. The base is L-shaped, and a rotating component is rotatably connected to the base by a pin. The rotating component is fastened and positioned to the light source carrier plate; the base and the lamp base shell are detachably connected. An integrally formed positioning seat is provided on the side wall of the lamp base shell, and a slot is provided at the bottom of the base. The positioning seat is matched and inserted into the slot for positioning.

[0004] However, the tri-proof light does not disclose whether its light source can be detached from the light source carrier plate. If it cannot be detached, it will be difficult to repair if the light source fails. Furthermore, if the light source needs to be replaced, the entire light source carrier plate or even the tri-proof light will need to be scrapped, which is costly.

[0005] In addition, the connection between the light source carrier plate and the lamp base shell means that when the lamp cover is opened during maintenance, the light source will be exposed, and maintenance personnel can easily touch the light source and cause damage. Furthermore, during the installation of the light source carrier plate, the exposed light source is easily damaged by external forces, and static electricity from the human body can easily damage the light source. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a lamp in which the light source can be detached from the support plate and the light source is not exposed when the light-transmitting lampshade is opened relative to the upper shell, in view of the current situation of the prior art.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a lamp, including an upper housing, a light-transmitting lampshade and a lamp plate assembly, wherein the top of the light-transmitting lampshade is open, the upper housing is detachably connected to the top opening of the light-transmitting lampshade, and the lamp plate assembly includes a support plate and a light source disposed on the support plate.

[0008] The light source is characterized in that it is detachably mounted on the support plate, and the two opposite sides of the support plate are referred to as the first side and the second side, respectively. The first side is rotatably connected to the light-transmitting lamp cover, and the axis of rotation extends along the length of the first side. The second side is detachably constrained to the light-transmitting lamp cover. When the support plate is assembled on the light-transmitting lamp cover and the light-transmitting lamp cover is open relative to the upper housing, the light source is located on the side of the support plate facing away from the opening of the light-transmitting lamp cover.

[0009] In order to allow the second side of the support plate to be detachably bound together with the light-transmitting lampshade, the support plate is provided with a limiting hole near the second side, and the light-transmitting lampshade is provided with a limiting protrusion. The limiting protrusion can be inserted into or pass through the limiting hole and detachably bound together with the support plate.

[0010] Alternatively, the support plate may have a limiting protrusion near the second side, and the light-transmitting lampshade may have a limiting hole. The limiting protrusion can be inserted into or pass through the limiting hole and detachably bound to the light-transmitting lampshade. The cooperation between the limiting protrusion and the limiting hole results in a simple structure.

[0011] To ensure the stability of the fit between the limiting protrusion and the limiting hole, one structural form is as follows: the support plate is bent from the second side to form a folded edge, the limiting hole is provided on the folded edge, the limiting protrusion is provided on the inner wall surface of the light-transmitting lampshade, the limiting protrusion is detachably inserted into the limiting hole, and the limiting protrusion extends laterally when the support plate is assembled on the light-transmitting lampshade and the light-transmitting lampshade is closed relative to the upper housing.

[0012] Alternatively, the support plate is bent from the second side to form a flange, the limiting protrusion is provided on the flange, and the limiting hole is provided on the inner wall surface of the light-transmitting lampshade. The limiting protrusion is detachably inserted into the limiting hole. When the support plate is assembled on the light-transmitting lampshade and the light-transmitting lampshade is closed relative to the upper housing, the limiting protrusion extends laterally. The flange can swing toward or away from the inner wall surface of the light-transmitting lampshade under the action of external force. When it is necessary to detach the limiting protrusion and the limiting hole, force can be applied to the flange to make the limiting protrusion disengage from the limiting hole. When it is necessary to constrain the limiting protrusion and the limiting hole together, during the rotation of the support plate, the limiting protrusion will interfere with the flange or the inner wall surface of the light-transmitting lampshade, thereby squeezing the flange and causing the flange to swing away from the inner wall surface of the light-transmitting lampshade. When the limiting protrusion is aligned with the limiting hole, the flange will swing toward the inner wall surface of the light-transmitting lampshade, the limiting protrusion will insert into the limiting hole, and the two will be constrained together.

[0013] Preferably, the support plate is further provided with a through hole, and the light-transmitting lampshade is provided with a insert piece. The insert piece can be detachably inserted into the hole. When the support plate is assembled on the light-transmitting lampshade and the light-transmitting lampshade is closed relative to the upper housing, the insert piece extends vertically.

[0014] Alternatively, the support plate may have an insert, and the light-transmitting lampshade may have an insertion hole. The insert is detachably inserted into the insertion hole. When the support plate is mounted on the light-transmitting lampshade and the lampshade is closed relative to the upper housing, the insert extends vertically. The cooperation between the insert and the insertion hole guides the support plate. When the support plate is about to rotate to the point where the limiting protrusion aligns with the limiting hole, the insert is inserted into the insertion hole. The support plate continues to rotate without lateral displacement, ensuring that the limiting protrusion aligns with the limiting hole.

[0015] To ensure the stability of the fit between the limiting protrusion and the limiting hole, another structural form is adopted: the limiting hole is cross-shaped, including intersecting and interconnected clearance openings and a locking slot. The limiting protrusion can pass through the clearance opening, and thereafter, the limiting protrusion can rotate around the center line of the limiting hole to a position corresponding to the locking slot. The length of the limiting protrusion is greater than the length of the locking slot. When it is necessary to position the carrier plate and the light-transmitting lampshade relative to each other, the limiting protrusion is aligned with the clearance opening. After the limiting protrusion passes through the clearance opening, it is rotated to align with the locking slot. Because the length of the limiting protrusion is greater than the length of the locking slot, the limiting protrusion will not disengage from the locking slot, thus achieving the relative positioning of the carrier plate and the light-transmitting lampshade. When disassembly is required, the limiting protrusion is rotated to align with the clearance opening, and the limiting protrusion passes through the clearance opening, thus disengaging from the limiting hole.

[0016] In order to achieve a rotatable connection between the first side of the support plate and the light-transmitting lampshade, one structural form is as follows: the first side of the support plate is rotatably connected to the light-transmitting lampshade via a hinge, and the rotation axis of the hinge extends along the length direction of the first side.

[0017] To achieve a rotatable connection between the first side of the support plate and the light-transmitting lampshade, another structural configuration is as follows: a rotating shaft is detachably mounted within the light-transmitting lampshade, and a connecting plate extends radially along the shaft. The support plate is mounted on this connecting plate, and the rotating shaft extends along the length of the first side of the support plate and is rotatable around its axis. Because the rotating shaft is detachably connected to the light-transmitting lampshade, the entire lamp panel assembly and rotating shaft can be removed for maintenance or replacement, making the process more convenient.

[0018] Preferably, the support plate is detachably mounted on the connecting plate. This allows for replacement or repair by simply removing the support plate.

[0019] In order to enable the detachable connection between the rotating shaft and the light-transmitting lamp cover, the light-transmitting lamp cover is provided with a group of positioning holes. The group of positioning holes includes positioning holes for positioning both ends of the rotating shaft respectively. One positioning hole is closed for one end of the rotating shaft to be inserted, and the other positioning hole is open on the side, allowing the other end of the rotating shaft to enter and exit the positioning hole through the opening.

[0020] To enable detachable connection between the light source and the carrier plate, the carrier plate is provided with a positioning assembly for detachably constraining the light source. The positioning assembly includes two positioning members arranged opposite each other. Each positioning member has an L-shaped longitudinal section, including mutually perpendicular vertical segments and horizontal segments. The vertical segments of the two positioning members are arranged opposite each other, and the horizontal segments of the two positioning members extend towards each other. When the carrier plate is assembled on the light-transmitting lampshade and the light-transmitting lampshade is closed relative to the upper housing, the vertical segments extend vertically and the horizontal segments extend horizontally.

[0021] The light source is a long, strip-shaped LED strip that can move along its length and is inserted between two vertical segments. The width of the light source is adapted to the distance between the two vertical segments, and the thickness of the light source is adapted to the distance between the horizontal segment and the support plate. The positioning assembly has a simple structure, and the light source is assembled on the support plate by passing through two positioning pieces, and disassembled by pulling the light source out between the two positioning pieces, making assembly and disassembly convenient.

[0022] Compared with the prior art, the advantages of this utility model are as follows: By setting the lamp panel assembly in the light-transmitting lamp cover, and assembling the support plate on the light-transmitting lamp cover, with the light-transmitting lamp cover in the open state relative to the upper shell, the light source is located on the side of the support plate facing away from the open light-transmitting lamp cover. In this way, when the upper shell is opened to inspect the lamp, the light source will not be exposed, avoiding contact with the light source by maintenance personnel and damage to the light source by external force, and also reducing the probability of the light source being damaged by static electricity from the human body.

[0023] In addition, the light source can be detachably mounted on the carrier plate, which can rotate relative to the light-transmitting lampshade. If the light source needs to be repaired, the carrier plate can be rotated first, and then the light source can be removed, making repairs more convenient. If the light source malfunctions and needs to be replaced, only the light source needs to be replaced, without scrapping the entire lamp panel assembly or even the entire lamp, thus saving costs.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0036] Example 1

[0037] Figures 1-8 A preferred embodiment of the lamp of this utility model is shown. The lamp includes an upper housing 1, a light-transmitting lampshade 2, and a lamp panel assembly 3. The top of the light-transmitting lampshade 2 is open, and the upper housing 1 is detachably connected to the top opening of the light-transmitting lampshade 2. The upper housing 1 and the light-transmitting lampshade 2 can be assembled in existing ways, such as screw connection, magnetic attraction, or the connection method of the upper housing and the light-transmitting lampshade in CN221483493U "A Tri-proof Lamp".

[0038] like Figure 6As shown, the lamp panel assembly 3 includes a support plate 31 and a light source 32 disposed on the support plate 31. The two opposite sides of the support plate 31 are referred to as the first side 3a and the second side 3b, respectively. The first side 3a is rotatably connected to the light-transmitting lampshade 2, and the axis of rotation extends along the length of the first side 3a. The second side 3b is detachably constrained to the light-transmitting lampshade 2. Thus, if the light source 32 needs maintenance or replacement, the support plate 31 can be rotated to allow the user to access the light source 32.

[0039] In this embodiment, the first side 3a is rotatably connected to the light-transmitting lampshade 2 in the following manner:

[0040] like Figure 7 , 8 As shown, a rotating shaft 4 is detachably installed in the light-transmitting lampshade 2. The rotating shaft 4 extends along the length direction of the first side 3a of the support plate 31, and the rotating shaft 4 can rotate about its axis.

[0041] Specifically, in this embodiment, the light-transmitting lampshade 2 is provided with a group of positioning holes, including positioning holes 21 for positioning both ends of the rotating shaft 4. One positioning hole 21 is closed for inserting one end of the rotating shaft 4, and the other positioning hole 21 has an opening 211 on its side (this positioning hole 21 can adopt a C-shaped hole structure). The other end of the rotating shaft 4 can enter and exit the corresponding positioning hole 21 through the opening 211. Preferably, the opening 211 is elastic, and its size in its natural state is smaller than the outer diameter of the rotating shaft 4. However, the opening 211 will expand when squeezed by the rotating shaft 4 to allow the rotating shaft 4 to pass through. When it is necessary to install the rotating shaft 4, first insert one end of the rotating shaft 4 into the closed positioning hole 21, and then insert the other end of the rotating shaft 4 into the positioning hole 21 through the opening 211 of the other positioning hole 21. When it is necessary to remove the rotating shaft 4, first pull the other end of the rotating shaft 4 out of the corresponding positioning hole 21 through the opening 211, and then pull one end of the rotating shaft 4 out of the corresponding positioning hole 21.

[0042] The rotating shaft 4 is provided with a connecting plate 41 extending radially therefrom, and the bearing plate 31 is detachably mounted on the connecting plate 41. In this embodiment, the bearing plate 31 and the connecting plate 41 are connected by screws 42. Of course, other connection methods are also possible, such as magnetic attraction, snap-fit ​​connection, etc.

[0043] Because the pivot 4 is detachably connected to the light-transmitting lamp cover 2, the entire lamp panel assembly 3 and pivot 4 can be removed for repair or replacement. Alternatively, only the support plate 31 can be removed for replacement or repair, which is even more convenient.

[0044] Because the support plate 31 is long and narrow, there are multiple rotating shafts 4, which are spaced apart along the length of the support plate 31. The connecting plate 41 on each rotating shaft 4 is connected to the support plate 31, so that the support plate 31 is connected at multiple points and the assembly stability is good.

[0045] The connection method between the first side 3a and the light-transmitting lampshade 2 in this embodiment can also adopt the connection method of embodiment 2.

[0046] In this embodiment, the second side 3b is detachably bound to the light-transmitting lampshade 2 in the following manner:

[0047] like Figure 6 As shown, a limiting hole 311 is provided on the support plate 31 near the second side 3b, and a limiting protrusion 22 is provided on the light-transmitting lampshade 2. The limiting protrusion 22 can be inserted into or pass through the limiting hole 311 and is detachably constrained to the support plate 31. Because the support plate 31 is elongated, in order to improve the assembly stability of the support plate 31, multiple limiting protrusions 22 are provided at intervals along the length direction of the support plate 31, and multiple limiting holes 311 are also provided at corresponding intervals.

[0048] Alternatively, the support plate 31 may have a limiting protrusion 22 near the second side 3b, and the light-transmitting lamp cover 2 may have a limiting hole 311. The limiting protrusion 22 may be inserted into or pass through the limiting hole 311 and may be detachably constrained together with the light-transmitting lamp cover 2.

[0049] Specifically, in this embodiment, the support plate 31 is bent from the second side 3b to form a folded edge 312. A limiting hole 311 is provided on the folded edge 312, and a limiting protrusion 22 is provided on the inner wall surface of the light-transmitting lampshade 2. The limiting protrusion 22 is detachably inserted into the limiting hole 311. When the support plate 31 is assembled on the light-transmitting lampshade 2 and the light-transmitting lampshade 2 is closed relative to the upper housing 1 (e.g.) Figure 1 (in the state of being), the limiting protrusion 22 extends laterally.

[0050] The folded edge 312 can swing toward or away from the inner wall surface of the light-transmitting lampshade 2 under the action of external force. When it is necessary to disengage the limiting protrusion 22 and the limiting hole 311, force can be applied to the folded edge 312 or the limiting protrusion 22 can be pried up with a screwdriver so that the limiting protrusion 22 disengages from the limiting hole 311. When it is necessary to constrain the limiting protrusion 22 and the limiting hole 311 together, during the rotation of the bearing plate 31, the limiting protrusion 22 will interfere with the folded edge 312, thereby squeezing the folded edge 312 and causing the folded edge 312 to swing away from the inner wall surface of the light-transmitting lampshade 2. When the limiting protrusion 22 is aligned with the limiting hole 311, the folded edge 312 will swing toward the inner wall surface of the light-transmitting lampshade 2, and the limiting protrusion 22 will be inserted into the limiting hole 311, and the two will be constrained together.

[0051] Alternatively, the support plate 31 can be bent from the second side 3b to form a folded edge 312, with a limiting protrusion 22 provided on the folded edge 312 and a limiting hole 311 provided on the inner wall surface of the light-transmitting lampshade 2. The limiting protrusion 22 can be detachably inserted into the limiting hole 311. When the support plate 31 is assembled on the light-transmitting lampshade 2 and the light-transmitting lampshade 2 is closed relative to the upper housing 1, the limiting protrusion 22 extends laterally.

[0052] In addition, in this embodiment, as Figure 8 As shown, the support plate 31 is also provided with a through insertion hole 313, and the light-transmitting lampshade 2 is provided with an insert 23. The insert 23 can be detachably inserted into the insertion hole 313. When the support plate 31 is assembled on the light-transmitting lampshade 2 and the light-transmitting lampshade 2 is closed relative to the upper housing 1, the insert 23 extends vertically. The cooperation between the insert 23 and the insertion hole 313 plays a guiding role for the support plate 31. When the support plate 31 is about to rotate to the point where the limiting protrusion 22 corresponds to the limiting hole 311, the insert 23 is inserted into the insertion hole 313. The support plate 31 will not shift laterally as it continues to rotate, so as to ensure that the limiting protrusion 22 can be aligned with the limiting hole 311.

[0053] Of course, it is also possible that the support plate 31 is provided with a insert 23 and the light-transmitting lamp cover 2 is provided with a socket 313. The insert 23 can be detachably inserted into the socket 313. When the support plate 31 is assembled on the light-transmitting lamp cover 2 and the light-transmitting lamp cover 2 is closed relative to the upper housing 1, the insert 23 extends vertically.

[0054] The connection method between the second side 3b and the light-transmitting lampshade 2 in this embodiment can also adopt the connection method of embodiment 2.

[0055] like Figure 8 As shown, the light source 32 is detachably mounted on the support plate 31. In this embodiment, the light source 32 is a long strip of light. The support plate 31 is provided with a positioning component for detachably constraining the light source. The positioning component includes two positioning members 33 arranged opposite to each other. The longitudinal section of each positioning member 33 is L-shaped, including a vertical section 331 and a transverse section 332 that are perpendicular to each other. The vertical sections 331 of the two positioning members 33 are arranged opposite to each other, and the transverse sections 332 of the two positioning members 33 extend toward each other. When the support plate 31 is assembled on the light-transmitting lamp cover 2 and the light-transmitting lamp cover 2 is closed relative to the upper housing 1, the vertical section 331 extends vertically and the transverse section 332 extends horizontally.

[0056] The light source 32 is movable along its length and is inserted between two vertical segments 331. The width of the light source 32 is adapted to the distance between the two vertical segments 331 to limit the light source 32 in the width direction. The thickness of the light source 32 is adapted to the distance between the horizontal segment 332 and the support plate 31 to limit the light source in the vertical direction. The light source 32 is assembled on the support plate 31 by passing through the two positioning members 33, and disassembled by pulling the light source out between the two positioning members 33, making disassembly and assembly convenient.

[0057] To improve the positioning stability of the light source on the carrier plate 31, there are at least two sets of positioning components, which are spaced apart along the length of the light source 32.

[0058] With the support plate 31 mounted on the light-transmitting lampshade 2 and the lampshade 2 open relative to the upper housing 1, the light source 32 is located on the side of the support plate 31 facing away from the open end of the light-transmitting lampshade 2, such as... Figure 2 As shown, when the upper housing 1 is opened to inspect the lamp, the light source 32 will not be exposed, which avoids the maintenance personnel from touching and damaging the light source 32 with external force, and also reduces the probability of the light source 32 being damaged by static electricity from the human body.

[0059] In this embodiment, if the light source 32 needs to be repaired or replaced, first use a screwdriver to pry up the limiting protrusion 22 so that the limiting protrusion 22 comes out of the limiting hole 311, then rotate the carrier plate 31 and pull the light source 32 out of the positioning assembly to remove the light source 32 from the carrier plate 31. This is more convenient for repair than removing the entire lamp panel assembly 3. If the light source 32 is faulty and needs to be replaced, only the light source 32 needs to be replaced, which will not cause the entire lamp panel assembly 3 or even the entire lamp to be scrapped, thus saving costs.

[0060] When it is necessary to install the lamp panel assembly 3 in the light-transmitting lamp cover 2, first install the rotating shaft 4 in the light-transmitting lamp cover 2, connect the support plate 31 and the connecting plate 41 with screws 42, rotate the support plate 31 until the limiting protrusion 22 is inserted into the limiting hole 311.

[0061] Example 2

[0062] Figures 9-10 Another preferred embodiment of the lamp of this utility model is shown. The difference between embodiment 2 and embodiment 1 is that the connection methods between the first side 3a and the second side 3b of the support plate 31 and the light-transmitting lamp cover 2 are different.

[0063] In this embodiment, the first side 3a is rotatably connected to the light-transmitting lampshade 2 in the following manner:

[0064] The first side 3a of the support plate 31 is rotatably connected to the light-transmitting lampshade 2 via a hinge 5, and the axis of rotation of the hinge 5 extends along the length of the first side 3a. The hinge 5's rotatable connection between the two components is existing technology and will not be described further here.

[0065] In this embodiment, the light-transmitting lampshade 2 is provided with a plate 23, and the supporting plate 31 is installed in the plate 23.

[0066] The connection method between the first side 3a and the light-transmitting lampshade 2 in this embodiment can also adopt the connection method of embodiment 1.

[0067] In this embodiment, the second side 3b is detachably bound to the light-transmitting lampshade 2 in the following manner:

[0068] The limiting hole 311 is cross-shaped, including a relief opening 3111 and a bayonet 3112 that intersect and communicate with each other. The limiting protrusion 22 can pass through the relief opening 3111, and thereafter the limiting protrusion 22 can rotate around the center line of the limiting hole 311 to a position corresponding to the bayonet 3112. The length of the limiting protrusion 22 is greater than the length of the bayonet 3112. When it is necessary to position the carrier plate 31 and the light-transmitting lamp cover 2 relative to each other, the limiting protrusion 22 is aligned with the clearance opening 3111. After the limiting protrusion 22 passes through the clearance opening 3111, the limiting protrusion 22 is rotated to align with the latch 3112. Because the length of the limiting protrusion 22 is greater than the length of the latch 3112, the limiting protrusion 22 will not come out of the latch 3112, thus achieving the relative positioning of the carrier plate 31 and the light-transmitting lamp cover 2. When it is necessary to disassemble, the limiting protrusion 22 is rotated to align with the clearance opening 3111, and the limiting protrusion 22 passes through the clearance opening 3111, thus coming out of the limiting hole 311.

[0069] The connection method between the second side 3b and the light-transmitting lampshade 2 in this embodiment can also adopt the connection method of embodiment 1.

[0070] In this embodiment, if the light source 32 needs to be repaired or replaced, first rotate the limiting protrusion 22 to correspond to the clearance opening 3111. The limiting protrusion 22 passes through the clearance opening 3111 and thus gets out of the limiting hole 311. Then rotate the carrier plate 31 to pull the light source 32 out of the positioning assembly and remove the light source 32 from the carrier plate 31.

[0071] When the light source 32 needs to be installed, first insert the light source 32 between the two positioning parts 33 of the positioning assembly, then rotate the support plate 31. After the limiting protrusion 22 passes through the clearance opening 3111, rotate the limiting protrusion 22 until it corresponds to the bayonet 3112. Because the length of the limiting protrusion 22 is greater than the length of the bayonet 3112, the limiting protrusion 22 will not come out of the bayonet 3112, thus realizing the assembly of the support plate 31 and the plate body 23.

[0072] In this utility model, the support plate 31 is assembled on the light-transmitting lampshade 2, meaning that both the first side 3a and the second side 3b of the support plate 31 are positioned with the light-transmitting lampshade 2. In this utility model, "horizontal" and "vertical" refer to the direction in which the lamp is installed on an external mounting base, such as a ceiling, or as shown in the attached drawings. Figure 1 The direction shown is the same as when the light fixture is installed on the ceiling.
