Technical Field
[0001] The invention relates to the technical field of connection of parts of lighting devices, and in particular to a connection structure and a lamp which are convenient for assembly, disassembly and maintenance of the lamp. Background Art
[0002] Some high-power lamps require regular maintenance after they are put into use. When maintaining the lamps, since high-power lamps are generally installed at high places, maintenance personnel need to operate at high places, which requires certain operating difficulties for maintenance personnel and is accompanied by certain safety risks. The connection of the lamp's own components and the distribution of the components in the lamp housing play a decisive role in the difficulty of the maintenance work.
[0003] In order to reduce the difficulty of lamp maintenance, people have designed some lamps that are convenient for maintenance personnel to perform maintenance. For example, a structure of an LED lamp that can be maintained in a modular manner is disclosed in a Chinese invention patent with authorization announcement number CN117781202B. The lamp is provided with components in a portion that can be rotated and turned out in a lamp housing, which not only reduces the number of components in the main part of the lamp housing, but also allows the components connected to the portion that can be rotated and turned out in the lamp housing to be exposed. At the same time, the space outside the lamp housing can also provide sufficient space for maintenance personnel to perform lamp maintenance, thereby achieving the purpose of facilitating maintenance personnel to perform lamp maintenance. However, if the two portions of the lamp housing that can be rotated and turned out cannot be turned out after being turned out, If the two are not fixed, the lamp shell part that can be rotatably turned out at the front end of the lamp shell may tilt backwards, causing damage to the lamp shell part that can be rotatably turned out at the rear end of the lamp shell and the parts connected to its surface; in addition, when the lamp shell part that can be rotatably turned out of the lamp shell is damaged and needs to be replaced, the above-mentioned lamp adopts a connection structure of the rotating end that is connected to the lamp shell axis through an axis-type connecting component. When replacing the lamp shell part that can be rotatably turned out of the lamp shell, the axis-type connecting component needs to be removed to disassemble the lamp shell part that can be rotatably turned out of the lamp shell. This connection structure of the rotating end affects the convenience of lamp maintenance. Summary of the invention

DETAILED DESCRIPTION
[0042] The present invention discloses a connection structure for facilitating installation and maintenance of lamps, such as Figure 1 and Figure 2 As shown in combination, the connection structure is provided in a lamp having a lamp housing 4, a heat sink 6, a rear cover 7, a power supply assembly 9 and a light-transmitting plate 10, and the lamp housing 4 is provided with a front cavity 41 and a rear cavity 42, and the connection structure includes:
[0043] The rotating assembly 1 is distributed at the front end of the lamp housing 4 and one end of the radiator 6, and the radiator 6 rotates with its position as the rotation center, and the radiator 6 is rotated out of the front cavity 41 and the radiator 6 is installed and removed from the lamp housing 4;
[0044] The buckle assembly 2 is distributed on the wall of the lamp housing 4 near the rear cavity 42 of the front cavity 41, and the buckle assembly 2 is clamped to the end of the heat sink 6 away from the rotating assembly 1 to limit the rotation of the heat sink 6;
[0045] The rotating assembly 1 is also distributed in the middle of the lamp housing 4 and one end of the rear cover 7, and the buckle assembly 2 is also distributed on the wall of the lamp housing 4 behind the rear cavity 42;
[0046] The positioning assembly 3 is distributed in the front cavity 41 and the rear cavity 42 and connected to the lamp housing 4 through a shaft-type connector, and the portion located in the front cavity 41 abuts against the edge of the light-transmitting plate 10 after rotation, thereby fixing the position of the light-transmitting plate 10 located in the front cavity 41, and the portion located in the rear cavity 42 abuts against the edge of the power supply assembly 9 after rotation, thereby fixing the position of the power supply assembly 9 located in the rear cavity 42;
[0047] When the positioning component 3 is subjected to a force in the same direction as the central axis of the shaft-type connecting part, the part located in the front cavity 41 or the part located in the rear cavity 42 rotates with the shaft-type connecting part as the rotation center and in a direction away from the light-transmitting plate 10 or the power supply component 9.
[0048] It should be noted that: when the lamp needs to be maintained, after the clamping effect of the end of the radiator 6 away from the rotating assembly 1 is released by the buckle assembly 2, the radiator 6 can be rotated out from the outside of the front cavity 41 by the rotating assembly 1, so that the front cavity 41 can be opened, and the tool-free opening of the front cavity 41 is realized. After the front cavity 41 is opened, the maintenance personnel can check the parts in the front cavity 41, which is convenient for the maintenance personnel to maintain the lamp parts in the front cavity 41 and the parts connected to the radiator 6; when the radiator 6 needs to be disassembled and replaced, the radiator 6 can be disassembled from the lamp housing 4 by further rotating the radiator 6; and when When the light-transmitting plate 10 needs to be replaced, the light-transmitting plate 10 can be pushed on the lamp housing 4 so that the light-transmitting plate 10 applies a force in the same direction as the central axis of the shaft-type connecting piece to the positioning assembly 3. After receiving this force, the end portion of the positioning assembly 3 connected to the non-shaft-type connecting piece will rotate in the direction away from the light-transmitting plate 10, so that the positioning assembly 3 abutting against the edge of the light-transmitting plate 10 is rotated out of the light-transmitting plate 10, and then the light-transmitting plate 10 is removed from the front cavity 41. The light-transmitting plate 10 in the front cavity 41 can be quickly installed and disassembled through the positioning assembly 3, and the installation and disassembly process does not require the use of tools. If it is necessary to inspect the parts in the rear cavity 42, it can be inspected through the buckle After the component 2 releases the clamping effect on the end of the rear cover 7 away from the front cavity 41, the rear cover 7 can be rotated out from the outside of the rear cavity 42 by the rotating component 1, so that the rear cavity 42 can be opened, and the rear cavity 42 can be opened without tools. After the rear cavity 42 is opened, the maintenance personnel can check the parts in the rear cavity 42, which is convenient for the maintenance personnel to maintain the lamp parts in the rear cavity 42 and the parts connected to the rear cover 7; and when it is necessary to disassemble the power supply component 9, the positioning component 3 in the rear cavity 42 is rotated to make the positioning component 3 in the rear cavity 42 rotated out from the surface of the power supply component 9, so as to remove the power supply component 9 from the rear cavity 42. The power supply assembly 9 in the rear cavity 42 can be quickly assembled and disassembled through the positioning assembly 3, and no tools are required during the assembly and disassembly process; at the same time, when the power supply assembly 9 is installed into the rear cavity 42, if the positioning assembly 3 in the rear cavity 42 abuts against the edge of the power supply assembly 9 incorrectly, the power supply assembly 9 will apply a force in the same direction as the central axis of the shaft-type connecting part to the positioning assembly 3 in the rear cavity 42, and after being subjected to this force, the positioning assembly 3 in the rear cavity 42 will rotate in the direction away from the power supply assembly 9, and automatically unscrew through the positioning assembly 3 in the rear cavity 42, thereby reminding the power supply assembly 9 that the position of the power supply assembly 9 is not completely fixed.
[0049] In addition, the heat sink 6 can be kept at a certain position outside the lamp housing 4 after the rotating assembly 1 is rotated and turned out of the lamp housing 4, or the connection with the lamp housing 4 is released so that the heat sink 6 can be assembled and disassembled on the lamp housing 4.
[0050] It needs to be further explained that if Figure 1 and Figure 3 As shown in combination, the portion of the rotating component 1 distributed on the radiator 6 is a hook 11, one end of the radiator 6 is provided with one or more hooks 11, the portion of the rotating component 1 distributed on the front end of the lamp housing 4 is a hook portion 12, the front end of the lamp housing 4 is provided with one or more hook portions 12, the radiator 6 is connected to the lamp housing 4 by hooking the hook 11 on the hook portion 12, and can rotate outside the front cavity 41 with the hook portion 12 as the rotation center.
[0051] Among them, the radiator 6 is hooked on the hook portion 12 through the hook 11, thereby forming a connection with the lamp housing 4, and can also be rotated through the rotating component 1 to realize the opening and closing control of the port of the front cavity 41; when the radiator 6 is outside the front cavity 41, the hook 11 is in a barbed hook state at the end of the radiator 6, and the moving path of the radiator 6 will be hindered by the lamp housing 4, and the hook 11 cannot be translated out of the hook portion 12 along the opening side thereof; and after the radiator 6 is rotated toward the outside of the front cavity 41 to be parallel to the lamp housing 4, the lamp housing 4 is not on the moving path of the radiator 6, and the hook 11 can be translated out of the hook portion 12 along the opening side thereof, thereby realizing the removal of the radiator 6.
[0052] Specifically, Figure 4 As shown, the axial cross-section of the end of the hook portion 12 in the axial direction is conical, and its radius increases with the increase of the distance from the center of the hook portion 12.
[0053] Among them, when the hook 11 moves toward the two axial ends of the hook part 12, the two axial ends of the hook part 12 will limit the position of the hook 11 to prevent the hook 11 from further moving in the axial direction of the hook part 12, thereby limiting the radiator 6, so that the radiator 6 can more accurately cover the outside of the front cavity 41 to seal the front cavity 41; and after the radiator 6 is turned out of the front cavity 41, the radiator 6 can be pushed to move in the axial direction of the hook part 12, so that the openings at both ends of the hook 11 in the axial direction are clamped at the axial end of the hook part 12, which can play a role in maintaining the position of the radiator 6 turned out of the front cavity 41.
[0054] More specifically, if Figure 5 and Figure 6As shown in the combination, the wall surface of the hook portion 12 at the transition position between the middle section and one of the axial ends is provided with a plurality of wedge-shaped recesses 13, and the plurality of recesses 13 are evenly distributed on the wall surface of the hook portion 12 in a ring shape with the axis of the hook portion 12 as the center, and one of the axial end surfaces of the hook 11 is fixedly connected with a semicircular ring-shaped connecting piece 14, and the inner edge of the connecting piece 14 is connected with a plurality of spring pieces 15 that are inclined and gathered toward the central axis of the hook 11, and the spring piece 15 is fan-shaped and its width increases with the increase of the distance from the connecting piece 14.
[0055] In the process of pushing the radiator 6 to move in the axial direction of the hook portion 12, the spring pieces 15 at both ends of the hook 11 in the axial direction are moved into the concave points 13, thereby limiting the rotation of the radiator 6. The distribution of the concave points 13 can be used together with the rotation angle, so that the radiator 6 turned out of the front cavity 41 can be temporarily fixed at a certain angle relative to the lamp housing 4. This not only allows the radiator 6 to be fixed in a position that is convenient for maintenance personnel to operate, but also prevents the circuits connecting the components on the radiator 6 from being damaged due to the radiator 6 rotating too fast.
[0056] It needs to be further explained that if Figure 7 and Figure 8As shown in combination, the portion of the buckle component 2 distributed on the wall of the lamp housing 4 near the rear cavity 42 of the front cavity 41 is an elastic buckle 21, and the walls of the lamp housing 4 on both sides of the rear end of the front cavity 41 are provided with bosses 22, one end of the elastic buckle 21 is connected to the boss 22 through a first matching hole 2101 to achieve its connection with the lamp housing 4, and both sides of the end of the radiator 6 away from the rotating component 1 are provided with card interfaces 23, and the elastic buckle 21 extends into the card interface 23 when the radiator 6 is not screwed out from the outside of the front cavity 41, and the end of the elastic buckle 21 away from the first matching hole 2101 is a pressing portion 212, and the two ends of the pressing portion 212 are respectively a limiting end 2121 and a connecting end 2122, and the limiting end 2121 and the connecting end 2122 are perpendicular to each other, and the two side walls of the lamp housing 4 located at the rear of the front cavity 41 are provided with limiting The fins 2121 and 2122 are connected to each other by a first arcuate arc 256 which is arranged on the outer side of the front cavity 41 and the fins 2122 are connected to each other by a second arcuate arc 26 ...
[0057] When it is necessary to fix the radiator 6 on the outside of the front cavity 41, the radiator 6 is pulled to rotate in the direction close to the front cavity 41, and the clamping block 26 on the outside of the clamping interface 23 will press on the protrusion 25 of the elastic buckle 21, and the second inclined surface 261 and the first inclined surface 251 are tangent and move relative to each other. As the radiator 6 continues to rotate in the direction close to the front cavity 41, the elastic buckle 21 will also continue to bend toward the rear cavity 42 side. After the second inclined surface 261 and the first inclined surface 251 are no longer in contact, the second limiting surface 262 and the second inclined surface 261 are The transition point is where the first fillet 253 is guided to the outside of the first limiting surface 252, and the elastic buckle 21 will gradually return to its original state. The second limiting surface 262 and the first limiting surface 252 will move relative to each other. After the radiator 6 is fixed to the outside of the front cavity 41, the second limiting surface 262 and the first limiting surface 252 abut against each other and form a parallel state. When the radiator 6 does not generate a large force, the elastic buckle 21 will limit the rotation movement of the radiator 6, thereby fixing the radiator 6 to the outside of the front cavity 41.
[0058] When releasing the fixing of the snap assembly 2 to the radiator 6, the pressing portion 212 on the elastic snap assembly 21 can be pressed in the direction of the rear cavity 42, so that the elastic snap assembly 21 will also bend continuously toward the rear cavity 42, and at the same time, the radiator 6 is pushed to rotate in the direction away from the front cavity 41. After the elastic snap assembly 21 is continuously bent and the transition between the second limiting surface 262 and the second inclined surface 261 is guided by the first fillet 253, there is no contact between the clamping block 26 and the elastic snap assembly 21, and the fixing of the radiator 6 by the snap assembly 2 can be released. When the elastic clip 21 is bent, the positioning end 2121 moves into the limiting groove 24 and abuts against the wall of the lamp housing 4 in the limiting groove 24, thereby limiting the portion of the elastic clip 21 outside the limiting end 2121 from further moving toward the wall of the lamp housing 4 on the side where the rear cavity 42 is located, thereby preventing the portion of the elastic clip 21 outside the limiting end 2121 from being hard squeezed against the wall of the lamp housing 4 when the elastic clip 21 is excessively bent, thereby causing permanent deformation, and preventing the portion of the elastic clip 21 outside the limiting end 2121 from being displaced after permanent deformation, thereby making it impossible to fix the radiator 6.
[0059] It needs to be further explained that if Fig. 9 and Fig.10 As shown in combination, the part of the positioning component 3 distributed in the front cavity 41 includes a first pressure block 31 and a spring 32. The middle part of the front cavity 41 is provided with a first matching groove 33 for matching with the light-transmitting plate 10. The wall surface of the front cavity 41 outside the first matching groove 33 is provided with a second matching hole 34. The shaft-like connecting piece is matched in the second matching hole 34. One end of the first pressure block 31 is provided with a through hole 35 with a diameter larger than the second matching hole 34. The shaft-like connecting piece passes through the through hole 35. The end of the shaft-like connecting piece away from the second matching hole 34 is provided with an end head 36 with a diameter larger than the second matching hole 34. One end of the spring 32 is fixedly connected to the end head 36. The other end of the spring 32 is fixedly connected to the wall of the first pressure block 31 on the outside of the through hole 35. The first pressure block 31 is arranged in a matrix distribution manner on the outside of the first matching groove 33. A limit block 37 is provided on the wall of the front cavity 41 on the outside of the second matching hole 34. The first pressure block 31 is provided with a second fillet 3101 and a third fillet 3102 on both sides of the end close to the limit block 37. The third fillet 3102 is close to the first matching groove 33 and the distance to the central axis of the shaft-type connecting part is smaller than the distance from the second fillet 3101 to the central axis of the shaft-type connecting part. The first pressure block 31 is provided with chamfers 3103 on both sides of the end of the first pressure block 31 located on the outside of the first matching groove 33.
[0060] After the heat sink 6 is screwed out from the outside of the front cavity 41, the light-transmitting plate 10 is pushed to move out of the first matching groove 33 from the end surface of the light-transmitting plate 10 that is not in the front cavity 41. In the process of the light-transmitting plate 10 moving out of the first matching groove 33, the light-transmitting plate 10 generates a force on the first pressing block 31 that is in the same direction as the central axis of the shaft-type connecting member. The end of the first pressing block 31 located on the outside of the first matching groove 33 is tilted in the direction away from the first matching groove 33 by the force. Since the distance from the third fillet 3102 to the central axis of the shaft-type connecting member is smaller than the distance from the second fillet 3101 to the central axis of the shaft-type connecting member, the part of the first pressing block 31 where the third fillet 3102 is located moves toward the first The rotation of part of the pressure block 31 will be restricted by the limit block 37. As the end of the first pressure block 31 located outside the first matching groove 33 is continuously pushed up and moved for a while by the light-transmitting plate 10, the part of the first pressure block 31 where the second fillet 3101 is located will rotate toward the part of the first pressure block 31 where the third fillet 3102 is located. At this time, the spring 32 is subjected to torsion, causing the end of the first pressure block 31 located outside the first matching groove 33 to rotate away from the light-transmitting plate 10 until the light-transmitting plate 10 no longer exerts a force on the first pressure block 31. Then the light-transmitting plate 10 can be removed from the front cavity 41, and the first pressure block 31 returns to the position outside the first matching groove 33 under the elastic recovery action of the spring 32.
[0061] In addition, when the light-transmitting plate 10 is loaded into the front cavity 41, the light-transmitting plate 10 generates a force on the first pressing block 31 in the same direction as the central axis of the shaft-type connecting member. After the end of the first pressing block 31 located outside the first matching groove 33 is subjected to the force, the chamfer 3103 provided at the end will contact the corner of the light-transmitting plate 10. Under the guiding action of the chamfer 3103 and the deformation action of the spring 32, the first pressing block 31 moves away from the first matching groove 33, and as the light-transmitting plate 10 continues to move, the first pressing block 31 moves away from the first matching groove 33. The end of a matching groove 33 will be tilted upward. As the first pressure block 31 continues to move away from the first matching groove 33 and the spring 32 deforms, the end of the first pressure block 31 is pushed out of the range of the first matching groove 33 by the light-transmitting plate 10, so that the light-transmitting plate 10 can be pressed into the first matching groove 33. After the light-transmitting plate 10 is fitted into the first matching groove 33, the spring 32 returns to its original state and drives the end of the first pressure block 31 to press on the edge of the light-transmitting plate 10, thereby fixing the position of the light-transmitting plate 10 in the first matching groove 33.
[0062] It needs to be further explained that if Fig.11As shown, the part of the rotating component 1 distributed on the rear cover 7 is a connecting arm 16, the connecting arm 16 is integrally formed with the rear cover 7 and a third matching hole 17 is provided at the end away from the rear cover 7, and fourth matching holes 18 are provided on both side walls of the lamp housing 4 in front of the rear cavity 42, and the rear cover 7 can be screwed out from the outside of the rear cavity 42 and screwed into the outside of the rear cavity 42 by inserting the rotating shaft into the third matching hole 17 and the fourth matching hole 18.
[0063] Among them, the rotating shaft is passed into the third matching hole 17 and the fourth matching hole 18 to connect the connecting arm 16 to the lamp housing 4, thereby realizing the connection between the back cover 7 and the lamp housing 4, and after the fixing effect of the snap assembly 2 on the back cover 7 is released, the back cover 7 can be rotated with the central axis of the rotating shaft as the rotation center, so that the back cover 7 can be screwed out from the outside of the rear cavity 42 and the back cover 7 can be screwed into the outside of the rear cavity 42, thereby controlling the opening and closing of the rear cavity 42.
[0064] It needs to be further explained that if Fig.12 and Fig.13 As shown in the figure, the portion of the buckle assembly 2 distributed on the wall of the lamp housing 4 behind the rear cavity 42 includes a snap-on portion 27, a connecting strip 28 and a fastener 29. The snap-on portion 27 is arranged on both sides of the end of the rear cover 7 away from the front cavity 41. The two side walls of the rear end of the lamp housing 4 have grooves 210, and a connecting seat 211 is arranged in the groove 210. The connecting seat 211 is provided with a second matching groove 2111. The middle section of the connecting strip 28 is matched in the second matching groove 2111, and the two ends of the connecting strip 28 are connected to the two sides of the fastener 29 in an axially connected manner. The cross-sectional shape of both the end of the fastener 29 away from the axis connected to the connecting strip 28 and the snap-on portion 27 is hook-shaped.
[0065] Among them, the operator can flip the fastener 29 with his fingers to rotate the fastener 29 relative to the connecting strip 28. The end of the fastener 29 away from the clamping portion 27 will swing outward under the action of the flipping of the fingers, and then the end of the fastener 29 is moved out from the clamping portion 27 by rotating the fastener 29 relative to the connecting strip 28, so that the clamping portion 27 and the fastener 29 are no longer clamped together in a hooked manner, and the connection between the end of the rear cover 7 away from the front cavity 41 and the lamp housing 4 is released. The rear cover 7 can be rotated out from the outside of the rear cavity 42 with its end connected to the axis of the lamp housing 4 as the rotation center to open the rear cavity 42. The operator can inspect the components in the rear cavity 42 and the components connected to the rear cover 7.
[0066] It needs to be further explained that if Figure 14~Figure 16As shown in the combination, the portion of the positioning component 3 distributed in the rear cavity 42 is the second pressing block 38, the power supply component 9 is arranged in the middle of the rear cavity 42 through the fixing plate 310, and the wall of the rear cavity 42 outside the fixing plate 310 is provided with a plurality of connecting columns 39, and the middle of the connecting column 39 is provided with a fifth matching hole, and the shaft-type connecting piece is matched in the fifth matching hole, one end of the second pressing block 38 is fixedly connected to the shaft-type connecting piece, and the second pressing block 38 is distributed in a matrix on the outside of the fixing plate 310, and the edge of the fixing plate 310 close to the connecting column 39 is provided with a fixing plate relative to the fixing plate 310 is an inclined guide plate 311, and the second pressure block 38 rotates with the shaft-type connecting piece matched in the fifth matching hole as the rotation center, and is screwed into the surface of the fixed plate 310 from the side of the guide plate 311 to fix the position of the power supply assembly 9. The end face of the second pressure block 38 abutting against the surface of the fixed plate 310 after rotation is an arc surface 381. When the guide plate 311 generates a force on the arc surface 381 in the same direction as the central axis of the shaft-type connecting piece, the second pressure block 38 rotates with the shaft-type connecting piece as the rotation center and in a direction away from the power supply assembly 9.
[0067] After the power supply assembly 9 is placed in the middle of the rear cavity 42 and located at the position of the rear cavity 42 on the inner side of the connecting column 39, the second pressure block 38 is rotated, and the end of the second pressure block 38 away from the shaft-type connecting piece side passes through the guide plate 311 and is screwed into the surface of the fixed plate 310, thereby fixing the position of the fixed plate 310 and thus achieving the position fixation of the power supply assembly 9; since there is a height difference between the guide plate 311 and the abutment position of the second pressure block 38 on the fixed plate 310, the setting of the arc surface 381 can make the end of the second pressure block 38 move more smoothly when passing through the transition between the fixed plate 310 and the guide plate 311; similarly, when the end of the second pressure block 38 away from the shaft-type connecting piece side passes through the guide plate 311 and is screwed out of the fixed plate 310, the rotation of the second pressure block 38 can be automatically guided by the inclination of the arc surface 381 and the guide plate 311, so that the second pressure block 38 automatically moves from the gap between the guide plate 311 and the fixed plate 310 The docking point rotates to the edge of the guide plate 311. For this reason, if the end of the second pressure block 38 away from the shaft-type connecting part side does not completely pass through the transition position between the guide plate 311 and the fixed plate 310 and abuts against the surface of the fixed plate 310, its position is still on the surface of the guide plate 311. At this time, the arc surface 381 of the second pressure block 38 is in contact with the surface of the guide plate 311, and the two are in a tangent state. The power supply component 9 will generate a force on the end of the second pressure block 38 away from the shaft-type connecting part in the same direction as the central axis of the shaft-type connecting part, so that the end of the second pressure block 38 where the arc surface 381 is located is pushed open and rotates in the direction away from the power supply component 9 with the shaft-type connecting part as the rotation center. When the end of the second pressure block 38 away from the shaft-type connecting part side is unscrewed on the surface of the guide plate 311, it proves that the second pressure block 38 has not fixed this position on the power supply component 9, and the maintenance personnel can adjust the position of the second pressure block 38 according to the situation.
[0068] The present invention also discloses a lamp, such as Figure 17~Figure 20As shown, it includes a lamp housing 4, a light source assembly 5, a radiator 6, a back cover 7, a sensor 8, a power supply assembly 9, a light-transmitting plate 10 and the above-mentioned connection structure, the light source assembly 5 is arranged in the radiator 6, the sensor 8 is matched with the surface of the lamp housing 4 outside the rear cavity 42, after the buckle assembly 2 releases the rotation restriction on the radiator 6 and the back cover 7, the radiator 6 is rotated out from the outside of the front cavity 41 through the rotating assembly 1, and a first operating space 101 is formed on the outside of both the front cavity 41 and the light source assembly 5, the back cover 7 is rotated out from the outside of the rear cavity 42 through the rotating assembly 1, and a second operating space 102 is formed on the outside of both the rear cavity 42 and the back cover 7, the rotation direction of the radiator 6 rotating out from the outside of the front cavity 41 to form the first operating space 101 is opposite to the rotation direction of the back cover 7 rotating out from the outside of the rear cavity 42 to form the second operating space 102, and the positions of the first operating space 101 and the second operating space 102 are respectively located on both sides outside the lamp housing 4.
[0069] It should be noted that the front cavity 41 and the rear cavity 42 in the lamp are both in the lamp housing 4, but the opening and closing ends of the two are not oriented in the same direction. Therefore, after the radiator 6 and the rear cover 7 are flipped out of the housing, there will be no interference when a space for maintenance personnel to operate is formed outside the front cavity 41 and the rear cavity 42 of the lamp. Moreover, the rotation and flipping direction of the radiator 6 outside the front cavity 41 is different from the rotation and flipping direction of the rear cover 7 outside the rear cavity 42, thereby avoiding the collision between the radiator 6 and the rear cover 7 and the components connected to the two during rotation. Compared with the prior art, the lamp with this connection structure will have a more obvious protective effect on the rotatable and flipped-out part of the lamp housing 4 and the components connected to the rotatable and flipped-out part during maintenance.
[0070] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
