[0033] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the scheme in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0036] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0037] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] Because the existing adjustable strip fill light has the problem that when only part of the handle is pulled out for fill light, the light strips on each level of the handle will also light up, which consumes a lot of power and is not conducive to long-term continuous use.

[0039] In order to solve the problems existing in the prior art, the utility model proposes a retractable lighting device, referring to Figures 1 to 3 , the lighting devices that can be accommodated in this application include:

[0040] The housing 1 is provided with an outlet 10;

[0041] A light strip 2, wherein the light strip 2 is at least partially accommodated in the housing 1, and one end of the light strip 2 can be exposed to the housing 1 through the outlet 10;

[0042] The belt-receiving mechanism 3 is arranged inside the housing 1 and connected to the other end of the light belt 2. The belt-receiving mechanism 3 is used to recycle the light belt 2 pulled out of the housing 1;

[0043] A power supply 4 is disposed inside the housing 1 and electrically connected to the light strip 2;

[0044] The switch assembly 5 includes a positive contact 51 and a negative contact 52 disposed near the outlet 10 of the housing 1. The portion of the light strip 2 exposed outside the housing 1 is electrically connected to the power source 4 via the positive contact 51 and the negative contact 52 to form an electrical circuit.

[0045] In this embodiment, the retractable lighting device of the present application solution can be applied to common scenes requiring fill light during the video recording process.

[0046] The retractable photography fill light device of this embodiment comprises a housing 1, a light strip 2, a retracting mechanism 3, a power source 4 and a switch assembly 5, wherein one end of the light strip 2 is exposed through an outlet 10 of the housing 1, so that the light strip 2 can be pulled out for use, and the other parts are stored inside the housing 1. The user can pull the end of the light strip 2 exposed to the housing 1, so that the light strip 2 contained in the housing 1 is gradually exposed to the housing 1 through the outlet 10, and the user can pull the light strip 2 to a desired length.

[0047] The light strip exposed to the shell 1 can form an electrical circuit with the power supply through the positive contact 51 and the negative contact 52 arranged near the exit of the shell 1, so that the part of the light strip 2 exposed to the shell 1 can be controlled to emit light for illumination, while the part of the light strip 2 contained in the shell 1 does not form an electrical circuit with the positive contact 51 and the negative contact 52 of the switch assembly 5, so the part of the light strip 2 contained in the shell 1 does not emit light, thereby saving electricity consumption to a certain extent, so that the sustainable use effect of the lighting device of the present application is better than that of the prior art.

[0048] After use, the light strip 2 pulled out of the shell 1 can be recovered by the belt-retracting mechanism 3, and all or at least part of the light strip 2 exposed outside the shell 1 can be recovered into the shell 1. The belt-retracting mechanism 3 can be set to an active or automatic retraction structure, that is, the light strip 2 can be actively retracted by the user after use, or the light strip 2 is automatically retracted by the belt-retracting mechanism 3 after use, so as to achieve quick storage.

[0049] In this embodiment, the lighting device with the above structure can achieve the following effects:

[0050] First, it improves convenience and storage: the light strip 2 can be stored in the housing 1, which reduces space when not in use, and can be pulled out to the required length when in use. The overall device is compactly designed, easy to carry and store, and suitable for a variety of occasions.

[0051] Second, to protect the light strip: the light strip 2 is stored in the housing 1 when not in use, which effectively protects the light strip 2 from damage by the external environment, such as dust, moisture, etc., thereby improving the durability and life of the light strip 2.

[0052] Third, flexible lighting: users can adjust the length of the light strip 2 as needed to achieve the desired lighting effect, thereby adapting to different usage scenarios, providing higher flexibility and convenience.

[0053] Fourth, energy saving and safety: through the positive contact 51 and the negative contact 52 of the switch assembly 5, it is ensured that only the part of the light strip 2 that is pulled out of the shell 1 is powered on for lighting, and the part that is not pulled out is not powered on for lighting, thereby avoiding unnecessary power consumption and improving energy efficiency.

[0054] Fifth, the operation is simple: the user only needs to simply pull out the light strip 2 for use, and after use, the light strip 2 can be stored through the belt collection mechanism 3, without the need for a complicated storage process, and the operation is convenient without complicated steps.

[0055] In summary, the present application scheme includes a shell 1, a light strip 2, a belt-retracting mechanism 3, a power supply 4 and a switch assembly 5. When in use, the user can pull out the light strip 2 from the shell 1. The light strip 2 pulled out of the shell 1 forms an electrical circuit with the power supply 4 through the positive contact 51 and the negative contact 52 of the switch assembly 5. The power supply 4 supplies power to make the light strip 2 pulled out of the shell 1 emit light for illumination. After use, the light strip 2 can be recovered into the shell 1 through the belt-retracting mechanism 3, which is convenient for storage and carrying. It achieves an effective lighting effect while also being convenient for storage, and is suitable for various photographic needs.

[0056] Please continue to refer to Figure 4 In a preferred embodiment, the light strip 2 proposed by the utility model includes a strip body 21 and a plurality of light-emitting components 22, the belt-retracting mechanism 3 is connected to the strip body 21, the plurality of light-emitting components 22 are arranged at intervals on the strip body 21, and the positive contact 51 and the negative contact 52 are electrically connected to the plurality of light-emitting components 22.

[0057] In this embodiment, the user can drive the end of the light strip 2 exposed outside the housing 1 to gradually pull the light strip 2 out of the housing 1. According to needs, the pulling length of the light strip 2 is adjusted to expose more light-emitting elements 22.

[0058] The working principle of the light strip 2 is based on the current passing through the light-emitting elements 22 (such as LED lamp beads) to make them emit light. Specifically, the current of the power supply 4 forms a circuit with each light-emitting element 22 on the light strip 2 pulled out of the housing 1 through the positive contact 51 and the negative contact 52, and the current flows through the light-emitting elements 22 on the strip body 21 pulled out of the housing 1, so that these light-emitting elements 22 generate light.

[0059] When the power is turned on, the current emitted by the positive pole of the power supply 4 flows from the positive contact 51 to the positive pole of each light-emitting component 22 of the part of the light strip 2 pulled out of the shell 1, and then flows through the light-emitting component 22, and then flows from the negative pole of the light-emitting component 22 to the negative contact 52 and flows back to the negative pole of the power supply 4, forming an electrical circuit, and the light-emitting components 22 pulled out of the shell 1 emit light for illumination.

[0060] In summary, this embodiment achieves the following effects by providing the light strip 2 of the above structure:

[0061] First, the lighting length can be flexibly adjusted: the user can adjust the length of the light strip 2 as needed to reveal more light-emitting elements 22, thereby flexibly controlling the lighting range to meet the needs of different scenes.

[0062] Second, uniform lighting effect: the light-emitting elements 22 are arranged at intervals on the strip-shaped body 21, and the current passes through the light-emitting elements 22 on the strip-shaped body 21 pulled out of the shell 1 to form a uniform light source, thereby ensuring the uniformity and consistency of the lighting effect and improving the lighting quality.

[0063] In some embodiments, a limiting structure 221 is provided at one end of the strip body 21 exposed from the housing 1, and the limiting structure 221 is used to engage the outlet 10. The limiting structure 221 engages the outlet 10 to facilitate the user to pull out the light strip 2, ensuring that the light strip 2 has a stable initial predetermined position.

[0064] In some embodiments, both sides of the strip body 21 are provided with light emitting elements 22. The strip body 21 has two opposite sides, at least one of which is provided with a plurality of light emitting elements 22 arranged at intervals, and both sides may also be provided with light emitting elements 22 according to actual needs.

[0065] The possible configurations of the light strip 2 are as follows:

[0066] Single-sided lighting: The light-emitting element 22 is only arranged on one side of the light strip 2, which is suitable for scenes requiring unidirectional lighting. The advantages are simple structure and easy control of light direction.

[0067] Double-sided lighting arrangement: The light-emitting elements 22 are arranged on both sides of the light strip 2, which is suitable for scenes requiring multi-directional lighting. The advantage is that it provides a wider lighting range and adapts to the needs of supplementary lighting at different angles.

[0068] Please continue to refer to Figure 5 In a preferred embodiment, the belt taking-up mechanism 3 proposed in the utility model includes an elastic belt taking-up member 31 and a reel 32, the reel 32 is arranged inside the shell 1, the elastic belt taking-up member 31 is coiled on the reel 32 in a disc shape, and the elastic belt taking-up member 31 is connected to the belt-shaped body 21.

[0069] In this embodiment, the belt taking-up mechanism 3 is provided with an elastic belt taking-up member 31 and a reel 32 for recovering the light strip 2. The elastic belt taking-up member 31 may use a spring, which is coiled around the reel 32 in a disc shape, and the outer end of the spring is connected to the light strip 2, so that the pulled-out light strip 2 can be automatically recovered. The reel 32 is the connection origin of the elastic belt taking-up member 31, and is used to fix one end of the elastic belt taking-up member 31.

[0070] The user pulls the end of the light strip 2 exposed outside the housing 1, driving the light strip 2 to gradually extend from the inside of the housing 1 to the outside of the housing 1, exposing the light-emitting element 22 on the strip body 21 to the outside of the housing 1. In the process of pulling the light strip 2, the clockwork spring is stretched, and the winding part begins to unfold, storing elastic potential energy. After use, the user releases the light strip 2, and the clockwork spring begins to automatically contract, releasing the stored elastic potential energy. The contraction force of the clockwork spring gradually pulls the light strip 2 back into the housing 1 until it is stored.

[0071] In summary, the belt-taking mechanism 3 in this embodiment realizes the automatic retraction and extension function of the light strip 2 through the cooperation of the elastic belt-taking member 31 and the reel 32, which has the advantages of simplicity, high efficiency, and space saving, greatly improving the storage and use experience of the lighting device of the present application, and can be automatically stored conveniently and quickly, which is more convenient to use than the active storage in the prior art.

[0072] Please continue to refer to Figure 3 and Figure 5 In a preferred embodiment, the retractable lighting device proposed by the utility model also includes a locking member 6, which is slidably connected to the shell 1, one end of which is exposed to the shell 1, and the other end extends into the shell 1 for abutting against the elastic belt-receiving member 31.

[0073] In this embodiment, the locking member 6 is slidably connected to the housing 1 , with one end of the locking member 6 extending into the interior of the housing 1 and the other end exposed outside the housing 1 .

[0074] Taking the elastic belt collecting member 31 as a clockwork spring as an example, by sliding the locking member 6, the end of the locking member 6 extending into the housing 1 can be made to abut against or away from the clockwork spring, so as to control the clockwork spring to be relatively static or movable with respect to the housing 1. That is, the locking member 6 can adjust the range of motion and the force of the clockwork spring through sliding action, thereby realizing the control of the extension and retraction of the light strip 2.

[0075] The user slides the locking member 6, and the end exposed outside the housing 1 moves, driving the end inside the housing 1 to act accordingly: when the end of the locking member 6 extending into the housing 1 abuts against the clockwork spring, the locking member 6 limits the further extension or contraction of the clockwork spring, and the extension or retraction of the light strip 2 is controlled. The user can adjust and set the fixed length of the light strip 2 exposed to the outside through the locking member 6 as needed. When the locking member 6 is away from the clockwork spring, the clockwork spring resumes normal elastic extension or contraction, allowing the light strip 2 to freely extend and retract. After use, the locking member 6 is driven so that it does not abut against the elastic belt-collecting member 31, and the elastic belt-collecting member 31 can pull the light strip pulled out of the housing 1 back into the housing 1 according to its own elastic reset.

[0076] That is, through the control effect of the sliding locking member 6, the user can quickly set and adjust the position of the light strip 2. In addition, the locking member 6 can effectively prevent the light strip 2 and the light-emitting member 22 from being retracted at an inappropriate time, ensuring the safety and stability of the device during use. In particular, during the shooting process, the locking member 6 can fix the position of the light strip 2 to prevent the light strip 2 from accidentally sliding. The sliding mechanism of the locking member 6 allows the user to flexibly adjust the length of the light strip 2 according to different shooting requirements to meet the needs of various shooting scenes. Whether a longer light strip 2 is needed to provide wide lighting, or a shorter light strip 2 is needed for local fill light, it can be quickly adjusted through the locking member 6.

[0077] In a preferred embodiment, the end of the locking member 6 extending into the housing 1 can be made of elastic material to avoid damaging the light-emitting member 22 .

[0078] The present application scheme realizes precise control and flexible operation of the retractable photographic fill light device by setting a locking member 6. The locking member 6 can control the extension and contraction of the elastic belt-receiving member 31 through sliding adjustment, so that the length and position of the light strip 2 connected to the elastic belt-receiving member 31 can be controlled, and the automatic retraction of the light strip 2 can be realized through the joint action of the locking member 6 and the elastic belt-receiving member 31, and the storage is convenient.

[0079] Please continue to refer to Figure 3 and Figure 5 In a preferred embodiment, the shell 1 proposed by the utility model includes a bottom shell 11 and a cover plate 12 connected to the bottom shell 11, the bottom shell 11 is constructed with a cavity, the light strip 2 is accommodated in the cavity, and the cover plate 12 covers the opening of the cavity; the reel 32 is arranged on the bottom shell 11 or the cover plate 12, and the elastic belt-winding member 31 is located between the bottom shell 11 and the cover plate 12.

[0080] In this embodiment, a cavity is designed inside the bottom shell 11 for accommodating the light strip 2, and the cover plate 12 can cover the opening of the cavity of the bottom shell 11 to protect the light strip 2 between the bottom shell 11 and the cover plate 12. The reel 32 can be installed on the bottom shell 11 or on the cover plate 12, and the elastic belt collecting member 31 is installed between the bottom shell 11 and the cover plate 12.

[0081] The housing 1 can provide good protection for the light strip, and the cover plate 12 and the bottom shell 11 together seal the cavity to prevent dust, water vapor and physical damage from affecting the light strip 2. The housing 1 has a compact structure, so that the lighting device can be easily stored and carried when not in use.

[0082] In some embodiments, the detachable connection between the bottom shell 11 and the cover plate 12 facilitates the disassembly and assembly and opening of the interior of the lighting device of the present application, and facilitates the replacement or maintenance of parts.

[0083] Please continue to refer to Figure 3In a preferred embodiment, the cavity proposed by the utility model is provided with at least one guide shaft 7, each guide shaft 7 is arranged near the outlet, the guide shaft 7 is rotatably connected to the shell 1, can rotate relative to the shell 1, and its peripheral wall can abut the light strip 2.

[0084] In this embodiment, the guide shaft 7 is installed inside the housing 1 and can rotate relative to the housing 1. A bearing can be installed on the guide shaft 7, a connecting column is provided inside the housing 1, and the connecting column is connected to the bearing to achieve the effect that the guide shaft 7 can rotate relative to the housing 1. The peripheral wall of the guide shaft 7 can contact the light-emitting member 22 on the light strip 2.

[0085] When the user drives the light strip 2, the light strip 2 can be gradually pulled out of the housing 1 from the inside. At this time, the plurality of light-emitting elements 22 on the light strip 2 can be sequentially abutted against the peripheral wall of the guide shaft 7 as the light strip 2 is driven, and the sequential contact of the plurality of light-emitting elements 22 causes the guide shaft 7 to rotate relative to the housing 1.

[0086] In summary, this embodiment achieves the following effects by providing the guide shaft 7 of the above structure:

[0087] First, reduce friction and wear: the self-rotation function of the guide shaft 7 ensures that the contact surface of the light strip 2 with the guide shaft 7 is always in a rolling state during the pulling out or retracting process, thereby reducing the probability of friction and wear between the strip body 21 and the light-emitting component 22 of the light strip 2 and the shell 1, and extending the service life of the light strip 2 and the light-emitting component 22.

[0088] Second, guidance and stability: the guide shaft 7 ensures that the light strip 2 moves along a predetermined path during the process of pulling out and retracting, avoiding the light strip 2 from getting entangled or stuck in the housing 1, thereby ensuring smooth and stable operation.

[0089] Third, protecting the light strip: the existence of the guide shaft 7 allows the light strip 2 to be evenly supported and guided when passing through the interior of the housing 1, thereby preventing the light strip 2 from being deformed or damaged due to uneven force.

[0090] Fourth, smooth operation: by installing bearings on the guide shaft 7, it can rotate smoothly, further reducing friction, ensuring that the process of pulling out and retracting the light strip 2 is smoother and more labor-saving.

[0091] Fifth, the service life of each component is extended: the guide shaft 7 reduces the direct friction between the light strip 2 and other components inside the housing 1, reduces the wear rate of the overall equipment, and extends the service life of the entire belt-taking mechanism.

[0092] In some embodiments, when a plurality of guide shafts 7 are provided, the guide shafts are spaced apart along the moving direction of the light strip 2 . The use of a plurality of guide shafts 7 can further enhance the effect of the above-mentioned provision of the guide shafts 7 .

[0093] The present application scheme achieves the goal of maintaining the stability of the light strip 2 through the above-mentioned arrangement: the guide shaft 7 provides additional support and stability by contacting and limiting the light-emitting component 22, thereby preventing the light strip 2 from shaking or sliding during use, improving the stability of the lighting, and ensuring the consistency and uniformity of the light source.

[0094] In a preferred embodiment, the outer diameter of the guide shaft 7 provided in the present invention is gradually reduced from both ends to the middle, and the middle of the guide shaft 7 can abut against the light-emitting component 22 .

[0095] In this embodiment, the guide shaft 7 is arranged in a columnar shape, and the outer diameter of the two ends of the guide shaft 7 is gradually reduced toward the middle of the guide shaft 7. The middle of the guide shaft 7 can abut the light-emitting component 22, that is, the middle of the guide shaft 7 is a concave structure compared to its two ends to reduce extrusion and protect the light-emitting component 22.

[0096] Since the light-emitting component 22 is arranged on the light strip 2, the thickness of the entire light strip 2 will be increased. When the light strip 2 is driven in the aforementioned embodiment, the tapered design makes the contact area gradually narrower, thereby dispersing the pressure at the initial contact stage, reducing the pressure on the light-emitting component 22, and protecting the light-emitting component 22 from damage.

[0097] The tapered design ensures that the guide shaft 7 is mainly in contact with the non-light-emitting part 22 of the light strip 2, avoiding direct squeezing of the light-emitting part 22, thereby protecting the light-emitting part 22 from damage. The durability and service life of the light strip 2 and the light-emitting part 22 are improved. The tapered design of the guide shaft 7 reduces the friction during the extension and retraction of the light strip 2, making the operation smoother and smoother. Users can easily adjust the length of the light strip 2, improving the convenience of use.

[0098] In a preferred embodiment, the guide shaft 7 can also be made of elastic materials such as silicone, that is, the guide shaft 7 is an elastic member, so that the light-emitting member 22 is buffered to a certain extent when contacting the guide shaft 7, so that the light-emitting member 22 is protected.

[0099] Through the above-mentioned configuration, the present application provides a smooth operating experience and a stable guiding function of the retractable photographic fill light device, which effectively improves the durability of the device and the user experience.

[0100] Please continue to refer to Figure 3 In a preferred embodiment, the power source 4 proposed by the present invention is installed on the inner wall of the bottom shell 11 or the cover plate 12 , and the bottom shell 11 or the cover plate 12 is provided with a charging port 110 for charging the power source 4 .

[0101] In this embodiment, the charging port 110 is disposed on the inner wall of the bottom shell 11 or the cover plate 12 and is connected to the circuit of the power source 4. Its main function is to charge the power source 4 inside the shell 1 by connecting to an external power source. The charging port 110 usually adopts a standard charging interface, such as a USB interface, to facilitate connection of various charging devices.

[0102] The user can connect an external power source (such as a charger, a computer USB port) to the charging port 110 and achieve electrical connection by inserting a corresponding charging cable. The external power source provides current to the charging port 110 through the charging cable, and the charging port 110 transmits the current to the internal power supply 4. The power supply 4 receives the current from the charging port 110, starts the charging process, and stores electrical energy. When the power supply 4 is fully charged, the charging process ends, and the user can disconnect the charging device. The electrical energy stored in the power supply 4 is used to power the light strip 2.

[0103] The charging port 110 allows the user to conveniently charge the power supply 4 without disassembling the power supply 4 or the device, which enhances the convenience of use. Through the charging port 110, the power supply 4 can replenish power at any time to ensure that the device will not be interrupted due to insufficient power during use, providing a continuous and stable fill light effect. The use of standardized charging interfaces (such as USB / TypeC) makes the charging device widely versatile, and users can use existing chargers, computers and other devices for charging without having to purchase special chargers.

[0104] This embodiment designs the charging port 110 with the above structure, so that the charging port 110 plays an important role in providing a convenient charging method, ensuring continuous power supply, and extending the service life, thereby improving the overall practicality and user experience of the lighting device of the present application.

[0105] Please continue to refer to Figure 2 and Figure 4 In a preferred embodiment, the positive pole of at least one light-emitting component 22 exposed outside the shell 1 proposed by the utility model is electrically connected to the positive contact 51, and the negative pole thereof is electrically connected to the negative contact 52, so that the light-emitting component 22 exposed outside the shell 1 forms an electrical circuit with the power source 4.

[0106] In this embodiment, the positive contact 51 and the negative contact 52 are respectively connected to the positive and negative electrodes of the light-emitting element 22 on the light strip 2 , and the light-emitting element 22 is electrically connected to the power source 4 through the positive contact 51 and the negative contact 52 .

[0107] Specifically, when the light strip 2 is pulled out of the shell 1, the positive and negative poles of the light-emitting element 22 located at the exit 10 are connected to the positive contact 51 and the negative contact 52. At this time, the power supply 4 provides electrical energy to make the light-emitting element 22 pulled out of the shell 1 emit light for illumination.

[0108] The positive pole of the light-emitting element 22 is electrically connected to the positive pole contact 51 through the light strip 2, ensuring that the electric energy can be smoothly transmitted to the positive pole of the light-emitting element 22. The negative pole of the light-emitting element 22 is electrically connected to the negative pole contact 52 through the light strip 2, completing the closure of the current loop. The current flows out from the positive pole of the power source 4, enters the positive pole of the light-emitting element 22 on the light strip 2 in contact with it through the positive pole contact 51, and after the current passes through the light-emitting element 22, it flows back to the negative pole of the power source 4 through the negative pole contact 52 connected to the light-emitting element 22, forming a complete electrical circuit. When the electrical circuit is formed, the current passes through the light-emitting element 22, causing it to emit light.

[0109] In summary, this embodiment reliably connects the positive and negative poles of the light-emitting component 22 to the power supply 4 through the positive contact 51 and the negative contact 52 to form a complete electrical circuit, ensuring that each light-emitting component 22 pulled out of the shell 1 emits light normally, thereby achieving reliable electrical connection and lighting functions.

[0110] Please continue to refer to Figure 4 In a preferred embodiment, the light strip 2 provided by the utility model further includes a plurality of positive contacts 23 and a plurality of negative contacts 24, each light-emitting element 22 is correspondingly connected to a positive contact 23 and a negative contact 24, each positive contact 23 is cascaded in sequence, and each negative contact 24 is cascaded in sequence;

[0111] A plurality of light emitting elements 22 are arranged in the middle of the strip-shaped body 21 , the positive contact 23 is arranged corresponding to the positive contact 51 , and the negative contact 24 is arranged corresponding to the negative contact 52 .

[0112] In this embodiment, when the user uses the light strip 2 and pulls it out of the housing 1, after determining the required length of the light strip 2, the elastic belt collecting member 31 is fixed by the sliding locking member 6 to fix the relative position of the light strip 2, so that the light strip 2 exposed outside the housing 1 maintains a certain length. At this time, the positive contact 51 and the negative contact 52 located at the outlet 10 are respectively in contact with the positive contact 23 and the negative contact 24 connected to the light-emitting member 22 located at this position, thereby forming an electrical circuit with the power supply 4, and taking the light-emitting member 22 abutted by the positive contact 51 and the negative contact 52 as a reference, the front light-emitting member 22 cascaded with the light-emitting member 22 (i.e., the light-emitting member 22 between the outlet 10 and the head end of the light strip 2 pulled out) lights up, while the rear light-emitting member 22 cascaded with the light-emitting member 22 (i.e., the light-emitting member 22 accommodated in the housing 1) does not light up, thereby achieving the effect of lighting up the light strip 2 pulled out of the housing 1, which is simple and effective, and can effectively save energy.

[0113] Please continue to refer to Figure 4 and Figure 6 In a preferred embodiment, the retractable lighting device provided by the present invention further includes a plurality of first unidirectional conductive elements 25 and a plurality of second unidirectional conductive elements 26, wherein:

[0114] Each positive contact 23 is electrically connected to a light-emitting element 22 in one direction through a first unidirectional conducting element 25; and

[0115] Any two adjacent positive contacts 23 are electrically connected via a second unidirectional conductive element 26 , and the current direction of the second unidirectional conductive element 26 is from the side of any two adjacent positive contacts 23 that is close to the outlet 10 to the side that is far away from the outlet 10 .

[0116] In this embodiment, diodes can be used for the first unidirectional conductive element 25 and the second unidirectional conductive element 26. Each positive contact 23 is electrically connected to a light-emitting element 22 through a first unidirectional conductive element 25. The first unidirectional conductive element 25 allows current to flow from the positive contact 23 to the light-emitting element 22, while preventing reverse current.

[0117] Two adjacent positive contacts 23 are electrically connected via a second unidirectional conductive element 26. The current direction of the second unidirectional conductive element 26 flows from the contact adjacent to the outlet 10 to the contact away from the outlet 10, ensuring that the current can only flow in one direction, and the side of any two adjacent positive contacts 23 adjacent to the outlet 10 points to the side away from the opening.

[0118] When the light strip 2 is pulled out of the housing 1, after determining the required length of the light strip 2, the elastic belt-collecting member 31 is fixed by driving the locking member 6 to fix the position of the light strip 2, so that the light strip 2 exposed outside the housing maintains a certain length. At this time, based on the light-emitting member 22 abutted by the positive contact 51 and the negative contact 52 located at the outlet 10, the front light-emitting member 22 cascaded with the light-emitting member 22 (i.e., the light-emitting member 22 between the opening and the free end of the light strip) lights up, while the rear light-emitting member 22 cascaded with the light-emitting member 22 (i.e., the light-emitting member 22 inside the housing 1) does not light up, thereby achieving the effect that the light strip 2 pulled out of the housing 1 lights up, while the light strip 2 accommodated in the housing 1 does not light up, which is simple and effective and can effectively save energy.

[0119] In some embodiments, a power switch may be provided for the user to actively control whether the power source 4 is turned on.

[0120] In a preferred embodiment, the positive contact 23 and the negative contact 24 of the present invention are spring-pin contacts.

[0121] In this embodiment, various types of contacts can be used as the positive contact 23 and the negative contact 24 . Preferably, the present application uses spring pin contacts as the positive contact 23 and the negative contact 24 .

[0122] In this embodiment, the spring pin contacts are used as positive and negative contacts to achieve the following effects:

[0123] First, reliable electrical connection: When the light strip 2 is pulled and retracted, each contact point needs to be constantly in contact with and separated from the contact head. Fixed contacts are prone to unstable electrical connection due to poor contact.

[0124] The spring pin contacts are elastic and can provide continuous pressure during the contact process, ensuring close contact between the contacts and the contacts, thereby maintaining a stable and reliable electrical connection.

[0125] Second, adaptive adjustment: When the light strip is pulled, the contact surface between the contact point and the contact head may change due to changes in position and angle.

[0126] The spring needle contacts have a certain degree of adaptability and can automatically adjust the contact pressure according to the position and angle of the light strip to ensure good contact at all times.

[0127] Third, reduce wear: Fixed contacts are prone to wear during repeated pulling, affecting contact quality and service life.

[0128] Due to its elastic design, the spring pin contact can disperse pressure during the contact process, reduce friction and wear, and extend the service life of the contacts and contacts.

[0129] Fourth, absorbing vibration and impact: the light strip 2 may be subjected to external vibration and impact during pulling and use, resulting in poor contact of contacts.

[0130] The spring pin contact can absorb vibration and impact through its elastic structure, maintain good contact between the contact and the contact head, and ensure the stability of the electrical connection.

[0131] Fifth, adaptability to multiple uses: the pulling and retracting of the light strip 2 needs to be repeated continuously during the use of the present application, and the fixed contacts are easily damaged by mechanical fatigue due to multiple contacts with the contacts, thus resulting in failure.

[0132] The spring pin contacts have good elastic recovery properties and can adapt to multiple pulling and retraction operations to maintain long-term stable electrical connections.

[0133] In summary, using spring pin contacts as the positive contact 23 and the negative contact 24 not only improves the reliability and stability of the electrical connection and prolongs the service life, but also enhances the convenience and adaptability of the light strip during pulling and retracting.

[0134] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
