Description

Technical Field

[0001] The invention relates to the technical field of lighting fixture design, and in particular to a telescopic fixture. Background Art

[0002] At present, in order to adjust the lighting height of the lamp, the lamp is generally installed on a telescopic rod, and the height of the lamp is adjusted by the telescopic movement of the telescopic rod. When the lamp is not in use, the telescopic rod is shortened for easy storage.

[0003] However, the lamp itself does not have a telescopic function. For some long strip lamps, due to the long length of the lamp itself, the length of the box required to store such long strip lamps is still relatively long, which is inconvenient to carry the lamp. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art that the lamp itself cannot be telescoped, resulting in a relatively long storage length and inconvenient carrying, thereby providing a telescopic lamp.

[0005] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0006] A lamp, comprising:

[0007] Lamp handle;

[0008] A first bracket, on which a first light-emitting member is disposed;

[0009] A second bracket extends in the same direction as the first bracket and is slidably connected to the first bracket along the length direction of the first bracket; a second light-emitting member is mounted on the second bracket, and the second light-emitting member extends in the same direction as the first light-emitting member and is not arranged on the same plane;

[0010] During the relative sliding of the second bracket and the first bracket, the second bracket has a contracted state in which the second light-emitting component is stacked with the first bracket so that the second light-emitting component and the first light-emitting component are stacked, and an extended state in which the second bracket extends outward relative to the first bracket so that the second light-emitting component and the first light-emitting component are arranged in sequence along the length direction of the first bracket.

[0011] Furthermore, the interior of the second bracket is provided with a cavity extending along its length direction, and the first bracket is slidably connected to the cavity of the second bracket; when the second bracket is in the contracted state, the first bracket is completely received in the cavity; when the second bracket is in the extended state, the first bracket extends outward from the cavity.

[0012] Furthermore, the second bracket is a semicircular long columnar structure, the side surface of the second bracket includes an arc side surface, and the second light-emitting element is installed on the horizontal top surface of the second bracket.

[0013] Furthermore, the cross-sectional shape of the cavity on the second bracket is semicircular, and the cross-sectional shape of the first bracket and the cross-sectional shape of the cavity on the second bracket are the same.

[0014] Furthermore, the first light-emitting member is connected to the lamp handle and has an accommodating gap with the first bracket. When the second bracket is in the retracted state, the second light-emitting member is placed in the accommodating gap and is shielded by the first light-emitting member.

[0015] Furthermore, a first slide groove extending along the length direction of the first bracket is provided on the horizontal top surface of the second bracket, and a first sliding block slidably connected to the first slide groove is provided on a side of the first light-emitting member facing the first bracket.

[0016] Furthermore, the outer wall of the first bracket is provided with a guide groove which is recessed inwardly and extends along the length direction of the first bracket, and the outer wall of the second bracket is recessed with a guide block which matches the shape of the guide groove.

[0017] Furthermore, the second bracket further includes an arc side surface, the guide block is arranged on the arc side surface of the second bracket, and the cross section of the guide block is arc-shaped.

[0018] Furthermore, the first light-emitting member is connected to the first bracket, and when the second bracket is in the retracted state, the second light-emitting member is shielded above the first light-emitting member.

[0019] Furthermore, a locking mechanism for locking the second bracket in the contracted state or in the extended state is provided between the first bracket and the second bracket.

[0020] Furthermore, the locking mechanism includes a locking block structure arranged on the first bracket, and a first locking hole and a second locking hole arranged on opposite ends of the second bracket in the length direction; the outer wall of the first bracket is provided with a mounting groove, and the locking block structure includes a first elastic member connected to the bottom of the mounting groove at one end and a card bead connected to the other end of the first elastic member, and the card bead extends from the mounting groove and into the first locking hole or the second locking hole under the action of the first elastic member to maintain the locking between the second bracket and the first bracket.

[0021] Furthermore, the first locking hole and the second locking hole are multiple arranged along the circumference and axis of the second bracket, and the locking block structure is also multiple arranged along the circumference and axis of the first bracket; and the multiple locking block structures and the multiple first locking holes and the multiple second locking holes are arranged one by one.

[0022] Further, the locking mechanism includes a limiting slot arranged on the outer wall of the first bracket, and a first wedge-shaped block and a second wedge-shaped block arranged on the inner walls at the opposite ends of the length direction of the second bracket and having inclined guide surfaces; the first wedge-shaped block cooperates with the limiting slot to lock the second bracket in the contracted state, and the second wedge-shaped block cooperates with the limiting slot to lock the second bracket in the extended state.

[0023] Furthermore, the light-emitting surface of the first light-emitting element and the light-emitting surface of the second light-emitting element are located on the same side of the lamp.

[0024] Furthermore, the first light-emitting member and the second light-emitting member are both in a long strip shape.

[0025] Furthermore, a second elastic member is provided in the cavity of the second bracket, and the other end of the second elastic member is connected to the first bracket.

[0026] Furthermore, the circuit on the first light-emitting component is connected to the power supply circuit, and a trigger mechanism for controlling the connection or disconnection of the circuit on the second light-emitting component and the power supply circuit is provided between the first light-emitting component and the second light-emitting component; when the second bracket is in an extended state, the trigger mechanism is triggered to connect the circuit on the second light-emitting component to the power supply circuit; when the second bracket is in a retracted state, the trigger mechanism is disconnected to disconnect the circuit on the second light-emitting component from the power supply circuit.

[0027] Further, the power supply circuit is arranged on a control circuit board, and the first light-emitting member and the second light-emitting member are both electrically connected to the control circuit board; the trigger mechanism includes a travel switch and a travel switch trigger block, one of the travel switch and the travel switch trigger block is arranged at one end of the first light-emitting member close to the second light-emitting member, and the other is arranged at one end of the second light-emitting member close to the first light-emitting member; when the second bracket is in an extended state, the travel switch trigger block contacts the travel switch to control the circuit on the second light-emitting member to be connected to the power supply circuit; when the second bracket is in a retracted state, the travel switch trigger block does not contact the travel switch to control the circuit on the second light-emitting member to be disconnected from the power supply circuit.

[0028] Further, the trigger mechanism includes a first electrical contact arranged on the first light-emitting member and a second electrical contact arranged on the second light-emitting member; when the second bracket is in an extended state, the second electrical contact contacts the first electrical contact to connect the circuit on the second light-emitting member with the circuit on the first light-emitting member; when the second bracket is in a retracted state, the second electrical contact disengages from the first electrical contact.

[0029] Furthermore, a first shell is sleeved around the first bracket and the first light-emitting element, and a second shell is sleeved around the second bracket and the second light-emitting element. The second shell is slidably connected to the first shell and embedded in the first shell.

[0030] Furthermore, the lamp handle is rotatably connected to the first bracket around an axis, and during the rotation of the lamp handle around the axis, the lamp handle has an unfolded position coaxially arranged with the first bracket and a folded position folded and pressed against an outer side wall of the first bracket.

[0031] Furthermore, the side of the lamp handle facing the first bracket has a first electric contact piece protruding outward, and the side where the first bracket and the lamp handle are connected is provided with a second electric contact piece; when the lamp handle is in the expanded position, the first electric contact piece contacts the second electric contact piece.

[0032] The technical solution of the present invention has the following advantages:

[0033] 1. The telescopic lamp provided by the present invention comprises a first bracket and a second bracket extending in the same direction and slidably connected, wherein a first light-emitting component is arranged on the first bracket, and a second light-emitting component is mounted on the second bracket, and the second light-emitting component and the first light-emitting component have the same extension direction and are arranged in a staggered manner; when the lamp is required to have a longer lighting length during use, the second bracket is slid to an extended state, at which time the first light-emitting component and the second light-emitting component are arranged in sequence, which can meet the lighting length requirement of the lamp; when storing, the second bracket is slid to a retracted state, and the second light-emitting component is arranged in a stacked manner with the first light-emitting component, which can shorten the overall length of the lamp (especially some long strip lamps), and accordingly, shorten the length of the box required to store such lamps, making it easier to carry the lamp.

[0034] 2. The telescopic lamp provided by the present invention has a cavity set inside the second bracket, and the first bracket is slidably connected to the structure in the cavity of the second bracket, which is conducive to maintaining the straightness of the second bracket during sliding, improving the stability of the first bracket and the second bracket during relative sliding, and further conducive to the reliability of contact between the electrical contacts on the second light-emitting component and the electrical contacts on the first light-emitting component.

[0035] 3. The telescopic lamp provided by the present invention has an internal mounting cavity of the first bracket, and components such as a power supply of the lamp can be mounted in the mounting cavity of the first bracket, thereby shortening the length requirement of the lamp handle and making it more convenient to carry.

[0036] 4. The telescopic lamp provided by the present invention has a first light-emitting member connected to the lamp handle and has an accommodation gap with the first bracket. When the second bracket is in the retracted state, the second light-emitting member is placed in the accommodation gap and is blocked by the first light-emitting member. Since the first light-emitting member is directly connected to the lamp handle, the second bracket will not affect the connecting wires between the first light-emitting member and the lamp handle during the retraction process. When the lamp is in the retracted state, the first light-emitting member can emit light normally and will not be blocked by the second light-emitting member. Therefore, the lamp has two different lighting lengths in the two states of shortening and extending, respectively, which overcomes the problem of the single lighting length and inability to adjust the lamp in the prior art, and is more practical. In addition, compared with the technical solution in which the second bracket is nested inside the first bracket, since the power supply of the lamp needs to be installed in the installation cavity of the first bracket, the second bracket of the same length as the first bracket cannot be completely retracted into the installation cavity of the first bracket, resulting in the overall storage length of the lamp still being relatively long. If a shorter second bracket is used, the lighting length of the lamp will be affected.

[0037] 5. The telescopic lamp provided by the present invention has a locking mechanism between the first bracket and the second bracket, which can lock the second bracket in a retracted state or in an extended state, which is beneficial to maintaining the stability of the lamp in its original state in the extended state or the stored state.

[0038] 6. The telescopic lamp provided by the present invention adopts a spring-loaded bead between the first bracket and the second bracket for limiting and locking, which has a simple structure and high stability. Moreover, after locking, it is easy for humans to use external force to overcome the limiting effect between the bead and the lock hole, thereby facilitating the telescopic adjustment and locking of the lamp.

[0039] 7. The telescopic lamp provided by the present invention has a second elastic member disposed between the first bracket and the second bracket, so that the lamp can be automatically telescoped and operated more conveniently.

[0040] 8. The telescopic lamp provided by the present invention has a lamp handle that is connected to the first bracket and is rotatable around an axis. During the rotation of the lamp handle around the axis, the lamp handle has an unfolded position that is coaxially arranged with the first bracket and a folded position that is folded and pressed against the outer wall of the first bracket. With this foldable structure of the lamp handle, the overall storage length of the lamp is smaller after the lamp handle is folded, making it more convenient to carry.

[0076] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0077] Embodiment 1

[0078] like Figure 1 A telescopic lamp shown in Figure 13 comprises a lamp handle 1, a first bracket 2, a second bracket 4, a first light-emitting component 3, a second light-emitting component 5, a first shell 8 and a second shell 9. The first bracket 2, the second bracket 4, the first light-emitting component 3, the second light-emitting component 5, the first shell 8 and the second shell 9 are all in the shape of long strips and extend in the same direction.

[0079] In this embodiment, the first bracket 2, the first light-emitting member 3 and one end of the first shell 8 are all fixedly connected to one end surface of the lamp handle 1, and there is an accommodation gap between the first light-emitting member 3 and the first bracket 2, and the first shell 8 is sleeved on the outer periphery of the first bracket 2 and the first light-emitting member 3. The second bracket 4 is slidably connected to the first bracket 2 along the length extension direction of the first bracket 2, the second light-emitting member 5 is mounted on the second bracket 4 and is staggered with the first light-emitting member 3, the second shell 9 is sleeved on the outer periphery of the second bracket 4 and the second light-emitting member 5, and the second shell 9 is slidably connected to the first shell 8 and embedded in the first shell 8.

[0080] During the relative sliding between the second bracket 4 and the first bracket 2, the second bracket 4 has a contracted state in which the second light-emitting member 5 and the first light-emitting member 3 are stacked and arranged with the first bracket 2, and an extended state in which the second light-emitting member 5 and the first light-emitting member 3 are arranged in sequence along the length direction of the first bracket 2 by extending outward relative to the first bracket 2. When the second bracket 4 is in the contracted state, the second light-emitting member 5 is placed in the accommodating gap and is blocked by the first light-emitting member 3.

[0081] For a telescopic lamp of this structure, since the second bracket 4 and the first bracket 2 extend in the same direction and are slidably connected, and the second light-emitting component 5 is staggered with the first light-emitting component 3, when the lamp is required to have a longer lighting length during use, the second bracket 4 is slid to an extended state, and the first light-emitting component 3 and the second light-emitting component 5 are arranged in sequence, which can meet the lighting length requirement of the lamp; when storing, the second bracket 4 is slid to a retracted state, and the second light-emitting component 5 and the first light-emitting component 3 are arranged in a stacked manner, which can shorten the overall length of the lamp (especially some long strip lamps). Correspondingly, the length of the box required to store such a lamp is shortened, making it easier to carry the lamp.

[0082] In this embodiment, the circuit on the first light-emitting member 3 is connected to the power supply circuit, and a trigger mechanism for controlling the connection or disconnection of the circuit on the second light-emitting member 4 and the power supply circuit is provided between the first light-emitting member 3 and the second light-emitting member 5; when the second bracket 4 is in the extended state, the trigger mechanism is triggered to connect the circuit on the second light-emitting member 5 to the power supply circuit; when the second bracket 4 is in the retracted state, the trigger mechanism is disconnected to disconnect the circuit on the second light-emitting member 5 from the power supply circuit. Specifically, the trigger mechanism includes a first electrical contact 301 provided on the first light-emitting member 3 and a second electrical contact 501 provided on the second light-emitting member 5; when the second bracket 4 is in the extended state, the second electrical contact 501 contacts the first electrical contact 301 to connect the circuit on the second light-emitting member 5 to the circuit on the first light-emitting member 3, and after the lamp is started, the first light-emitting member 3 and the second light-emitting member 5 can be powered on and emit light at the same time. When the second bracket 4 is in the retracted state, the second electrical contact 501 is out of contact with the first electrical contact 301. After the lamp is started, only the first light-emitting member 3 is powered on to emit light, so that the lamp can be powered on to emit light in the shortened state. Therefore, the lamp has two different lighting lengths in the shortened and extended states, respectively, which overcomes the problem that the lighting length of the lamp in the prior art is single and cannot be adjusted, and is more practical. In addition, the first light-emitting member 3 is provided with a third contact 302. When the second bracket 4 is in the retracted state, the second electrical contact 501 is in contact with the third contact 302, but at this time, the circuit on the second light-emitting member 5 is not connected to the circuit on the first light-emitting member 3, and the third contact 302 only plays a protective role for the second electrical contact 501.

[0083] In this embodiment, the second bracket 4 is provided with a cavity arranged along the length extension direction thereof, and the first bracket 2 is slidably connected in the cavity of the second bracket 4; when the second bracket 4 is in a contracted state, the first bracket 2 is completely received in the cavity of the second bracket 4; when the second bracket 4 is in an extended state, the first bracket 2 extends outward from the cavity. The structural form in which the first bracket 2 is slidably connected in the cavity of the second bracket 4 is conducive to maintaining the straightness of the second bracket 4 during the sliding process, improving the stability of the first bracket 2 and the second bracket 4 during the relative sliding process, and further conducive to the reliability of the contact between the electrical contacts on the second light-emitting member 5 and the electrical contacts on the first light-emitting member 3.

[0084] In this embodiment, the second bracket 4 is a long cylindrical structure with a semicircular cross section, the cross section of the inner cavity of the second bracket 4 is also semicircular, the first bracket 2 is a long cylindrical structure with a semicircular cross section, and the cross section of the first bracket 2 is the same as the cross section of the inner cavity of the second bracket 4, so as to facilitate the sliding fit between the first bracket 2 and the second bracket 4. In other replaceable embodiments, the cross section of the inner cavity of the second bracket 4 can also be circular or polygonal, and accordingly, the shape and size of the cross section of the first bracket 2 remain the same as the shape and size of the cross section of the inner cavity of the second bracket 4. The first bracket 2 is also provided with an installation cavity inside, which can provide installation space for components such as the lamp power supply, thereby reducing the length requirement of the lamp handle 1, which is conducive to further shortening the overall storage length of the lamp.

[0085] In this embodiment, since the first bracket 2 is closer to the lamp handle 1 than the second bracket 4, in order to facilitate the arrangement of the internal circuits of the lamp, the lamp power supply is only suitable for installation in the installation cavity of the first bracket 2, and the installation space inside the first bracket 2 will be partially occupied; compared with the technical solution in which the second bracket 4 is nested inside the first bracket 2, the second bracket 4 with the same length as the first bracket 2 cannot be completely retracted into the installation cavity of the first bracket 2, resulting in the overall storage length of the lamp still being relatively long. If a shorter second bracket 4 is used, the lighting length of the lamp will be affected.

[0086] In this embodiment, the side surface of the second bracket 4 includes an arc side surface 401 and a horizontal top surface 402. The horizontal top surface 402 of the second bracket 4 is provided with a groove for installing the second light-emitting member 5, and the upper surface of the second light-emitting member 5 is not higher than the top opening of the groove. The horizontal top surface 402 of the second bracket 4 is also provided with a first slide groove 403 located on both sides of the second light-emitting member 5. The extension direction of the first slide groove 403 is the same as the length extension direction of the first light-emitting member 3. The first light-emitting member 3 is provided with a first slider 303 slidably connected to the first slide groove 403 on the side facing the first bracket 2. When the second bracket 4 is in an extended state, the first light-emitting member 3 is overheadly arranged directly above the second light-emitting member 5, and the second light-emitting member 5 is blocked by the first light-emitting member 3. Since the first light-emitting member 3 is directly connected to the lamp handle 1, the second bracket 4 will not affect the connection wires between the first light-emitting member 3 and the lamp handle 1 during the contraction process. When the lamp is in a contracted state, the first light-emitting member 3 can emit light normally and will not be blocked by the second light-emitting member 5, so the lighting length of the lamp can be adjusted, which is more practical.

[0087] In this embodiment, the outer wall of the first bracket 2 is provided with an inwardly recessed guide groove 201, the extension direction of the guide groove 201 is the same as the length extension direction of the first bracket 2, and the arc side surface 401 of the second bracket 4 is recessed with a guide block 404 matching the shape of the guide groove 201, and the cross sections of the guide groove 201 and the guide block 404 are both arc-shaped. Through the guiding effect between the guide block 404 and the guide groove 201, the first bracket 2 and the second bracket 4 can better maintain relative sliding along the length extension direction thereof.

[0088] In this embodiment, a locking mechanism for locking the second bracket 4 in a retracted state or in an extended state is further provided between the first bracket 2 and the second bracket 4. The locking mechanism can lock the second bracket 4 in a retracted state or in an extended state, which is beneficial for maintaining the stability of the original state of the lamp in the extended state or the shortened state.

[0089] Specifically, the locking mechanism includes a locking block structure 6 arranged on the first bracket 2, and a first locking hole 405 and a second locking hole 406 arranged at opposite ends of the length direction of the second bracket 4. The outer peripheral wall of the first bracket 2 is provided with a mounting groove 202, and the locking block structure 6 includes a first elastic member 61 connected at one end to the bottom of the mounting groove 202 and a bead 62 connected to the other end of the first elastic member 61. Under the action of the first elastic member 61, the bead 62 extends from the mounting groove 202 and extends into the first locking hole 405 or the second locking hole 406 to maintain the locking between the second bracket 4 and the first bracket 2. Specifically, the first elastic member 61 is a spring; a plurality of mounting grooves 202 are evenly spaced along the circumference of the outer wall of the first bracket 2, and a spring and a bead 62 are installed in each mounting groove 202. The first locking hole 405 and the second locking hole 406 are provided in plurality along the circumference and axis of the second bracket 4, and the locking block structure 6 is also provided in plurality along the circumference and axis of the first bracket 2. The plurality of locking block structures 6 correspond to the plurality of first locking holes 405 and the plurality of second locking holes 406. The method of limiting and locking by using a spring-loaded bead 62 has a simple structure and high stability; and after locking, it is convenient for manual external force to overcome the limiting effect between the bead 62 and the locking hole, so as to facilitate telescopic adjustment and locking of the lamp.

[0090] In this embodiment, the first shell 8 and the second shell 9 are both made of light-transmitting materials to protect the first light-emitting member 3 and the second light-emitting member 5 inside. The first light-emitting member 3 and the second light-emitting member 5 both include a long strip-shaped light board, and the light board is provided with a plurality of LED lamp beads arranged at intervals along the length extension direction thereof. Specifically, the first shell 8 and the second shell 9 are both cylindrical structures.

[0091] In this embodiment, the first light-emitting member 3 and the second light-emitting member 5 are both in the shape of long strips, and the light-emitting surface of the first light-emitting member 3 and the light-emitting surface of the second light-emitting member 5 are located on the same side of the lamp.

[0092] Embodiment 2

[0093] like Fig.14 The telescopic lamp shown in Figure 22 is different from the first embodiment in that the first light-emitting member 3 is fixedly connected to the first bracket 2, and there is no accommodation gap between the first light-emitting member 3 and the first bracket 2; when the second bracket 4 is in the retracted state, the second light-emitting member 5 blocks the upper part of the first light-emitting member 3. When the second bracket 4 is in the extended state, the electrical contact below the second light-emitting member 5 contacts the electrical contact on the first light-emitting member 3, and after the lamp is started, the first light-emitting member 3 and the second light-emitting member 5 can be powered on and emit light at the same time.

[0094] In this embodiment, the first bracket 2, the second bracket 4, the first shell 8 and the second shell 9 are all in a square cylindrical structure. A second elastic member 7 is connected to the cavity of the second bracket 4, and the other end of the second elastic member 7 is connected to the first bracket 2. The second elastic member 7 is specifically a spring. The spring is arranged between the first bracket 2 and the second bracket 4, which can realize automatic extension and retraction of the lamp and make the operation more convenient.

[0095] In this embodiment, a control switch for controlling the extension and start-up of the lamp is disposed on the lamp handle 1 .

[0096] In this embodiment, the locking mechanism includes a limiting card slot 203 provided on the outer wall of the first bracket 2, and a first wedge-shaped card block 407 and a second wedge-shaped card block 408 provided on the inner walls at opposite ends of the length direction of the second bracket 4 and having an inclined guide surface; the limiting card slot 203, the first wedge-shaped card block 407 and the second wedge-shaped card block 408 are all trapezoidal. The first wedge-shaped card block 407 cooperates with the limiting card slot 203 to lock the second bracket 4 in a retracted state, and the second wedge-shaped card block 408 cooperates with the limiting card slot 203 to lock the second bracket 4 in an extended state.

[0097] In this embodiment, the lamp handle 1 is connected to the first bracket 2 by rotation around an axis. During the rotation of the lamp handle 1 around the axis, the lamp handle 1 has an unfolded position coaxially arranged with the first bracket 2 and a folded position folded against the outer wall of the first bracket 2. With this foldable structure of the lamp handle 1, the overall storage length of the lamp is smaller after the lamp handle 1 is folded, making it more convenient to carry.

[0098] In this embodiment, the side of the lamp handle 1 facing the first bracket 2 has a first electric contact 101 protruding outward, and the side where the first bracket 2 and the lamp handle 1 are connected is provided with a second electric contact 204; when the lamp handle 1 is in the unfolded position, the first electric contact 101 contacts the second electric contact 102. Such a configuration facilitates the control of the on-off of the circuit on the lamp handle 1 and the circuit on the first bracket 2, thereby controlling the on-off of the lamp.

[0099] Embodiment 3

[0100] like Fig.23-28 shows a telescopic lamp, which is different from the embodiment 1 in that the specific structure of the locking mechanism is different, and a sliding gap is provided between the outer peripheral wall of the first bracket 2 and the inner peripheral wall of the second bracket 4. The locking mechanism includes a non-slip sheet 205 fixedly connected to the outer side wall of the end of the first bracket 2 away from the lamp handle 1, and a sleeve 409 fixedly connected to the inner wall of the end of the second bracket 4 close to the lamp handle 1. The non-slip sheet 205 and the sleeve 409 are used to increase the sliding damping between the first bracket 2 and the second bracket 4; when the second bracket 4 is in an extended state, the non-slip sheet 205 and the sleeve 409 are limited and abutted to prevent the second bracket 4 from being separated from the first bracket 2. Specifically, the shape of the non-slip sheet 205 matches the shape of the first bracket 2, and the outer wall of the non-slip sheet 205 is provided with a plurality of convex ribs protruding outward, and the plurality of convex ribs are evenly spaced. A limiting column is provided on the sleeve 409, and a limiting hole is provided on the second bracket 4. The limiting column extends into the limiting hole so that the sleeve 409 is fixedly installed on the second bracket 4; similarly, a limiting column is also provided on the anti-slip sheet 205, and a limiting hole is also provided on the first bracket 2. The limiting column extends into the limiting hole so that the anti-slip sheet 205 is fixedly installed on the first bracket 2.

[0101] Embodiment 4

[0102] A telescopic lamp, such as Fig.29 As shown in Figure 30, the difference from the first embodiment is that the structure of the trigger mechanism is different, a control circuit board 10 is arranged in the first bracket 2, and a power supply circuit for supplying power to the first light-emitting member 3 and the second light-emitting member 5 is arranged on the control circuit board 10, and the first light-emitting member 3 and the second light-emitting member 5 are both electrically connected to the control circuit board 10. Specifically, the circuit on the first light-emitting member 3 is electrically connected to the power supply circuit on the control circuit board 10 through an electrical connector, and the circuit on the second light-emitting member 5 is electrically connected to the power supply circuit on the control circuit board 11 through a wire 11. In an alternative embodiment, the circuit on the first light-emitting member 3 can also be electrically connected to the power supply circuit on the control circuit board 10 through a wire, and the control circuit board 10 can also be arranged in the lamp handle 1.

[0103] In this embodiment, the trigger mechanism includes a travel switch 12 and a travel switch trigger block 13. The travel switch 12 is installed at one end of the first light-emitting member 3 close to the second light-emitting member 5 and is arranged facing the second light-emitting member 5; the travel switch trigger block 13 is installed at one end of the second light-emitting member 5 close to the first light-emitting member 3 and is arranged facing the first light-emitting member 3. When the second bracket 4 is in an extended state, the travel switch trigger block 13 contacts the travel switch 12 to control the circuit on the second light-emitting member 5 to be connected with the power supply circuit on the control circuit board 10; when the second bracket 4 is in a retracted state, the travel switch trigger block 13 does not contact the travel switch 12 to control the circuit on the second light-emitting member 5 to be disconnected from the power supply circuit on the control circuit board 10. The trigger mechanism composed of the travel switch 12 and the travel switch trigger block 13 has the advantages of simple structure, easy implementation and low production cost. In an alternative embodiment, the installation positions of the travel switch 12 and the travel switch trigger block 13 can also be interchanged.

[0104] In summary, the telescopic lamp provided in the embodiment of the present invention adopts a structural design in which the second bracket 4 and the first bracket 2 are slidably connected, and the second light-emitting member 5 is staggered with the first light-emitting member 3. When the lamp is required to have a longer lighting length during use, the second bracket 4 is slid to the extended state. At this time, the first light-emitting member 3 and the second light-emitting member 5 are arranged in sequence, which can meet the lighting length requirement of the lamp; when storing, the second bracket 4 is slid to the contracted state, and the second light-emitting member 5 is stacked with the first light-emitting member 3, which can shorten the overall length of the lamp (especially some long strip lamps). Correspondingly, the length of the box required to store such lamps is shortened, which facilitates the carrying of the lamp. In addition, the lamp has two different lighting lengths in the shortened and extended states, respectively, which overcomes the problem of a single lighting length and inability to adjust the lamp in the prior art, and is more practical.

[0105] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
