Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more specifically, to a multi-functional tool lamp. Background Technology

[0002] With the widespread use of automobiles, they have become a common means of transportation. However, when a car malfunctions, mechanics often need lighting tools to inspect and repair the faulty area, especially in the front area such as the engine compartment. When the hood is open, external light is blocked, making additional light sources crucial. Currently, mechanics primarily rely on handheld work lights or long, rectangular lighting tools fixed to a bracket when illuminating the front of the car or engine compartment. However, these existing technologies have several shortcomings. Handheld work lights require the mechanic to hold them, restricting the freedom of hand operation, leading to low repair efficiency and sometimes requiring multiple people to complete the task, which is extremely inconvenient. While fixing the work light to a bracket and suspending it from the hood can free up the hands to some extent, this method has significant stability issues. The light fixture is prone to falling due to insecure hooks, potentially injuring the mechanic or damaging the hood surface due to the hooks. Furthermore, the light source of the long, rectangular lighting fixture is longer than its base, making it unstable when placed at the front of the engine, further increasing the difficulty of use and safety hazards. Utility Model Content

[0003] This utility model discloses a multi-functional tool lamp, which aims to solve the problems mentioned above.

[0004] The present invention adopts the following solution:

[0005] A multi-functional tool lamp includes a base and a light source rotatably connected to the base, and further includes:

[0006] A first lever force resistance mechanism connects the base to one end of the light source, and adapts the light source to rotate around the base, and provides damping force when the light source rotates around the base;

[0007] The bottom cover is connected to the base via a second lever force resistance mechanism and can provide damping force when the bottom cover rotates around the base;

[0008] The length of the light source is longer than the length of the base.

[0009] Furthermore, the second leverage resistance mechanism includes a rotating tooth disposed on the bottom cover and a rotation limiting block connected to the rotating tooth. The rotation limiting block is elastically connected to the base via an elastic element. The bottom cover is hinged to the base via the rotating tooth. The rotation limiting block is provided with at least one engagement groove suitable for engaging with the rotating tooth to resist the leverage force transmitted from the light source to the base.

[0010] Furthermore, the rotation limiting block is located in the middle of the base, or at both ends of the extension of the base; the rotation limiting block is provided with two meshing grooves to be adapted to simultaneously mesh with two meshing teeth of the rotating tooth.

[0011] Furthermore, the length of the light source is 2-5 times the length of the base.

[0012] Furthermore, a magnetic element is provided inside the bottom cover.

[0013] Furthermore, a rotating block is hinged to one end of the base away from the bottom cover. The rotating block is connected to the light source through a first fixed block. The rotating block and the first fixed block are rotatably connected through a first lever force resistance mechanism. The first lever force resistance mechanism includes a fixed tooth disposed on the base and a stop block disposed on the rotating block. The stop block is engaged with the fixed tooth to form a lever force resistance mechanism.

[0014] Furthermore, it also includes a bracket that is deployably connected to the other end of the light source, having an unfolded state and a folded state, and in the unfolded state being adapted to jointly support the light source with the base.

[0015] Furthermore, a second fixing block is provided at the end of the light source away from the base, and a rotating connector is rotatably connected to the second fixing block, and the bracket is rotatably connected to the rotating connector.

[0016] Furthermore, the light source includes a metal housing, a light-transmitting lampshade, and a light-emitting element; wherein the light-transmitting lampshade is embedded in the metal housing, and the light-emitting element is disposed inside the light-transmitting lampshade.

[0017] Furthermore, the distance between the light-emitting element and the light-transmitting lamp cover is 2mm to 8mm.

[0018] Beneficial effects:

[0019] Through the design of the first and second lever force resistance mechanisms, luminaires with longer light sources can effectively resist leverage forces, significantly improving their stability. The bracket design allows the luminaire to be stably placed on non-adhesive surfaces, further enhancing its applicability.

[0020] Furthermore, the handheld long lamp of this utility model has the following specific advantages: First, it significantly improves ease of operation. The lamp can be easily fixed through magnetic adsorption and bracket support design, eliminating the need for manual gripping and facilitating single-person operation. Second, it significantly improves the stability of the lamp. The rotating teeth and spring mechanism effectively resist leverage forces, and the bracket design further enhances the lamp's stability. Third, it ensures safety, avoiding the risk of falling that occurs with traditional hook-and-mount methods, protecting the safety of maintenance personnel and vehicle surfaces. Fourth, it has a wide range of applications, suitable for both localized lighting under the hood and as a floodlight, adapting to various maintenance scenarios. Fifth, it offers good flexibility; the light source can be adjusted in multiple directions and angles to meet the lighting needs of different positions and angles.

[0021] This invention provides a highly efficient, stable, and safe handheld long lamp through innovative structural design and functional optimization, particularly suitable for engine compartment lighting in automotive repair scenarios. This lamp solves many problems in existing technologies, significantly improving repair efficiency and user experience, and has broad market application prospects. Attached Figure Description

Detailed Implementation

[0032] Combination Figures 1 to 4 As shown, this embodiment provides a multi-functional tool lamp, including a base 1 and a light source 2 rotatably connected to the base 1. It also includes: a first lever force resistance mechanism 3, connecting one end of the base 1 and the light source 2; a bottom cover 6, which is rotatably connected to the base 1 through a second lever force resistance mechanism 4; the light source 2 is longer than the base 1.

[0033] In this embodiment, the length of the light source 2 is greater than the length of the base 1. Preferably, the length of the light source 2 is between 2 and 5 times the length of the base 1, to ensure that the lamp can provide uniform lighting effects over a large area. This ratio optimizes the spatial dimension matching between the light source 2 and the base 1, allowing the light source 2 to have sufficient extension length to expand the lighting coverage, while the base 1 maintains a relatively short structure, thereby achieving balance in the center of gravity distribution and preventing the base 1 from tipping over due to the light source 2 being too long and unable to be effectively supported.

[0034] In existing technologies, the length of the light source in handheld lighting fixtures with a base is generally about 1:1 with the base. Slightly longer or shorter light sources prevent the center of gravity from shifting outwards, which could cause the fixture to tip over. Excessively long light sources are typically suspended. Compared to existing technologies, the length-to-base-1 ratio of the light source 2 in existing elongated lighting tools is not optimized. An excessively long light source 2 makes it difficult for the base 1 to provide effective support, causing the fixture to easily tip over due to a high or shifted center of gravity. This solution limits the length ratio of the light source 2 to the base 1 and combines it with a lever-force resistance mechanism. This allows the fixture to maintain a wide range of illumination while achieving stable placement through optimized center of gravity distribution and support structure, avoiding the stability problems caused by imbalanced dimensions in existing technologies. This embodiment solves the problem of the base 1 being unable to be stably placed due to the excessive length of the light source 2 in elongated lighting fixtures. The specific ratio of the light source 2 to the base 1 allows the fixture to achieve stable balance through the base 1 when unfolded, while the extended length of the light source 2 still meets the needs of wide-range illumination, effectively eliminating the safety hazards caused by tipping.

[0035] Combination Figures 1 to 7As shown, the first lever force resistance mechanism 3 refers to a torque balancing component installed at the connection between the base 1 and the light source 2. Specifically, it can be implemented using a meshing structure of meshing teeth and a stop block 32, used to counteract the lever effect generated by the suspended end of the light source 2. The second lever force resistance mechanism 4 refers to a rotation limiting component connecting the bottom cover 6 and the base 1. Specifically, it can be implemented using a rotation limiting block 41 with a meshing groove 411 and a rotation tooth 42, used to prevent the bottom cover 6 from rotating accidentally under external force.

[0036] Specifically, the light source 2 is mounted on the base 1 via a rotating connection structure. When the angle of the light source 2 is adjusted, the fixed teeth 31 in the first lever force resistance mechanism 3 and the stop block 32 generate a biting force, preventing the light source 2 from rotating unexpectedly due to its own weight or external force. The bottom cover 6 is connected to the base 1 via a rotation limiting block 41 with an elastic element 43. During rotation, the meshing groove 411 and the rotating teeth 42 form a staged limiting, ensuring that the contact surface between the base 1 and the ground remains stable.

[0037] Compared to existing technologies, this solution utilizes a leverage mechanism to achieve stable support while maintaining portability, significantly improving its anti-tipping ability. Regarding the issue of center-of-gravity shift in long, narrow light fixtures, existing technologies typically rely on a weighted base 1; this solution achieves adaptive balance by dynamically adjusting the support point position. Through these technical solutions, this application frees up maintenance personnel's hands and prevents accidental detachment of the light fixture due to unstable hooks. The adjustable angle of the light source 2 maintains a stable posture, adapting to the lighting needs of different maintenance locations.

[0038] In this embodiment, the base 1 integrates a battery and a control PCB board. The battery powers the light source 2, while the control PCB board supports brightness adjustment, allowing users to adjust the brightness of the lamp according to their needs. One end of the bottom cover 6 has an extension 61, which is connected to the base 1 via a pivot. The extension 61 is provided with rotating teeth 42. In one embodiment, the rotating teeth 42 can be located in the middle of the extension 61; in another embodiment, the rotating teeth 42 can be located at both ends of the extension 61.

[0039] Combination Figures 5 to 8As shown, the rotating tooth 42 refers to a rigid toothed structure fixedly connected to the bottom cover 6. Specifically, it can be implemented using an injection-molded metal insert or an integrally molded gear structure, used to convert the rotational motion of the bottom cover 6 into tooth surface contact force. The rotation limiting block 41 refers to a rigid component with a meshing groove 411, the shape of which matches the tooth profile of the rotating tooth 42 to form a meshing surface. The elastic element 43 refers to an element that generates elastic restoring force, specifically implemented using a helical spring, maintaining the meshing contact between the rotation limiting block 41 and the rotating tooth 42 through a pre-compression state. The meshing groove 411 refers to a groove structure provided on the rotation limiting block 41, its depth and sidewall inclination angle designed to form a surface contact with the tooth tip of the rotating tooth 42. When the rotating tooth 42 is subjected to leverage force, the sidewall of the meshing groove 411 decomposes the force into vertical pressure and horizontal resistance.

[0040] Specifically, when the bottom cover 6 tends to rotate relative to the base 1, the lever force transmitted by the light source 2 is conducted through the bottom cover 6 to the rotating tooth 42, forcing the rotating tooth 42 to rotate. At this time, the rotation limiting block 41, through the preload of the elastic element 43, keeps the meshing groove 411 in contact with the tooth surface of the rotating tooth 42, and the rotational motion of the rotating tooth 42 is blocked by the side wall of the meshing groove 411. When the lever force acts on the rotating tooth 42, the meshing groove 411 decomposes the rotational force into two components: the pressure perpendicular to the meshing surface is absorbed by the compressive deformation of the elastic element 43, and the shear force parallel to the meshing surface is transmitted to the base 1 body through the rotation limiting block 41. The reaction force generated by the elastic element 43 during compression continuously pushes the rotation limiting block 41 into contact with the rotating tooth 42, ensuring that at any rotation angle, the rotating tooth 42 has at least one meshing groove 411 that meshes with its tooth surface. This structure, through a multi-point contact mechanical decomposition method, disperses the lever force concentrated at the hinge point to the overall support structure of the base 1.

[0041] Compared to existing technologies, traditional work lamp base 1 and cover connections often employ single-point snap-fit ​​or friction damping structures, which are prone to snap-fit ​​breakage or damping failure when subjected to the leverage force generated by the elongated light source 2. This solution utilizes the multi-tooth surface contact formed by the meshing groove 411 of the rotating tooth 42 and the limiting block 41 to decompose the leverage force into axial pressure and radial resistance, reducing the stress on a single tooth surface to below the material's yield strength. Compared to a single-point snap-fit ​​structure, the meshing contact area between the meshing groove 411 and the rotating tooth 42 can be increased by approximately 3-5 times, while the continuous pre-tightening force of the elastic element 43 prevents loosening of the connection due to material creep.

[0042] Through the above technical solution, this application effectively reduces the stress concentration problem at the connection of the base 1 caused by the excessive length of the light source 2, and prevents the bottom cover 6 from rotating unexpectedly during the placement or transportation of the lamp. In the scenario of car engine compartment maintenance, this structure can also withstand the vibration and impact generated when the hood is opened and closed, ensuring the stable fixation of the work light on the edge of the engine compartment and avoiding the risk of the lamp falling.

[0043] In a preferred embodiment, the rotation limiting block 41 is provided with two meshing grooves 411 to simultaneously engage with the two meshing teeth of the rotating tooth 42. The meshing grooves 411 can be specifically designed as trapezoidal or rectangular grooves, with their depth matching the tooth height of the rotating tooth 42 to form a meshing contact surface. When the bottom cover 6 rotates relative to the base 1, the two meshing teeth of the rotating tooth 42 are respectively embedded into the two meshing grooves 411 of the rotation limiting block 41. Under the action of leverage, the contact surfaces of the two meshing teeth and the corresponding meshing grooves 411 share the load, resulting in the pressure being evenly distributed to the two meshing points. Due to the symmetrical layout of the double-meshing structure, the deflection torque generated during rotation is offset by the constraint force of the meshing grooves 411 on both sides, thereby preventing tooth disengagement caused by uneven force distribution in a single meshing groove 411.

[0044] Compared with the prior art, this solution increases the load distribution area through the symmetrical and synchronous meshing of the double meshing groove 411 and the double meshing teeth, effectively suppressing the axial displacement tendency of the rotating teeth 42 under the action of leverage force. Through the above technical solution, this application can prevent meshing failure caused by the transmission of leverage force at the connection between the bottom cover 6 and the base 1, ensuring that the lamp maintains a stable connection state when the angle is frequently rotated and adjusted, and avoiding the risk of accidental loosening or tipping due to single-point meshing disengagement.

[0045] In this embodiment, a magnetic component 62 is provided inside the bottom cover 6. The magnetic component 62 refers to a component with magnetic attraction function, which can be implemented using a permanent magnet or an electromagnet, and its magnetic strength can be selected according to the actual application requirements. The bottom cover 6 has an internal accommodating space for installing the magnetic component 62. Specifically, the magnetic component 62 can be integrated into the bottom cover 6 through an array arrangement, and can be magnetically attracted to the metal surface of the engine hood. The bottom cover 6 is rotatably connected to the base 1, so that the lamp can adapt to different installation angle requirements when it is attracted and fixed. The magnetic force of the magnetic component 62 acts on the contact surface between the bottom cover 6 and the metal, generating sufficient friction to resist the lever torque generated by the excessive length ratio of the light source 2, and prevent the lamp from tipping over. The internal accommodating space of the bottom cover 6 can be designed as a groove or a snap-fit ​​structure, and the magnetic component 62 is fixed therein by adhesive or embedding, ensuring that the magnetic surface is flush with the outer surface of the bottom cover 6, so as not to affect the appearance integrity. Compared with the prior art, the existing lamps rely solely on the external hook mechanism for fixation, which has the problems of unstable hooking, damage to the vehicle surface, and inconvenient installation. This solution utilizes the built-in magnetic component 62 on the bottom cover 6 to directly adhere to the metal surface, eliminating the need for an external hook structure. This avoids the risk of hooking off and eliminates scratches and damage to the vehicle body surface. Furthermore, the magnetic fixing method simplifies the operation, allowing for single-handed positioning and fixing of the light fixture, improving maintenance efficiency. It also adapts to different installation angle requirements, ensuring the safety and convenience of maintenance operations.

[0046] Combination Figures 1 to 8As shown, in this embodiment, a rotating block 7 is hinged to the end of the base 1 away from the bottom cover 6. The rotating block 7 is connected to the light source 2 through a first fixed block 8. The rotating block 7 and the first fixed block 8 are connected by a first lever force resistance mechanism 3. The first fixed block 8 is rotatably connected to the rotating block 7. The first lever force resistance mechanism 3 includes a fixed tooth 31 disposed on the base 1 and a stop block 32 disposed on the rotating block 7. The stop block 32 and the fixed tooth 31 are engaged to form a lever force resistance mechanism. The rotating block 7 is an intermediate connecting component that enables multi-directional rotation between the light source 2 and the base 1. Specifically, it can be a block with a shaft hole that cooperates with the hinge shaft of the base 1 to achieve the rotation function. The hinge structure of the rotating block 7 provides the light source 2 with a first degree of rotational freedom. The first fixed block 8 refers to a rigid connecting component that connects the rotating block 7 and the light source 2. It includes a pressure block 81 with a rotating shaft 811 and a cover plate 82. The rotating shaft 811 is adapted to be inserted into the rotating block 7 and rotate within the rotating block 7 to provide a second degree of rotational freedom. Here, the hinge axis of the rotating block 7 is perpendicular to the rotation axis of the rotating shaft 811, so that the light source 2 has a larger angle adjustment range. The gear block 32 refers to a positioning component with meshing teeth. It maintains a meshing state with the fixed teeth 31 through elastic preload and uses the frictional resistance of the tooth surface to resist the lever force generated by the rotation of the light source 2. The fixed teeth 31 refers to a toothed positioning hole structure provided on the base 1. Specifically, it can be formed by stamping continuously distributed trapezoidal tooth grooves at the end of the base 1. The tooth groove spacing matches the tooth shape of the gear block 32 to form a multi-level positioning gear.

[0047] The hinge structure between the rotating block 7 and the base 1 allows the light source 2 to rotate horizontally around the end of the base 1. The rotational connection between the first fixed block 8 and the rotating block 7 allows the light source 2 to adjust its pitch angle. During the rotation of the light source 2, the meshing position of the stop block 32 and the fixed tooth 31 automatically switches to adjacent tooth slots, forming a segmented positioning effect. The rotating block 7 decomposes the leverage force transmitted by the light source 2 into a component force perpendicular to the hinge axis. Through the meshing of the fixed tooth 31 and the stop block 32, the torsional stress is converted into tooth surface contact pressure, effectively reducing the load on the hinge part of the base 1. This solution, through the combination of dual rotation fulcrums and gear meshing structure, achieves multi-directional adjustment while constructing a mechanical torque cancellation mechanism, overcoming the tendency of the elongated light source 2 to rotate during rotation. This solution utilizes the rigid contact characteristics of gear meshing to ensure positioning reliability, solving the problem that the elastic snap-fit ​​positioning structure in the prior art is prone to elastic failure when subjected to continuous torque.

[0048] Through the above technical solution, this application effectively prevents the lamp from shaking or falling off due to the excessive length of the light source 2, and maintains a stable engagement state at any adjustment angle. The synergistic effect of the rotating block 7 and the fixed tooth 31 transforms the leverage force transmitted by the light source 2 into the normal pressure of the meshing tooth surface, significantly reducing stress concentration at the hinge of the base 1. The meshing positioning mechanism of the stop block 32 and the fixed tooth 31 realizes the step-by-step locking function in stepless adjustment, ensuring that the light source 2 can still maintain the set angle under vibration. The dual rotation structure enables the lamp to have multi-dimensional adjustment capabilities, while improving the overall structural stability through a mechanical decomposition mechanism.

[0049] In a preferred embodiment, a bracket is provided at the end of the light source furthest from the base. The bracket has an unfolded form and a folded form on the light source, and in the unfolded state, it is suitable for the base 1 to jointly support the light source 2. In the unfolded state, the bracket 5 supports the other end of the light source. Through the dual-point support structure of the base 1 and the bracket 5, the bracket 5 effectively suppresses the leverage effect of the elongated light source 2 after unfolding, achieving reliable placement in a confined space. In the folded state, all components are compactly folded, facilitating transportation and carrying.

[0050] The bracket 5 refers to a support component that can rotate around an axis. Specifically, it can be implemented using one or two foldable metal rods. When unfolded, it forms a support surface with the base 1; when folded, it is stored close to the surface of the light source 2. The bracket 5 can be stored on one or both sides of the light source 2 in its folded state. When only the base 1 and bottom cover 6 are used for support, the bracket 5 can be folded. When both the bracket 5 and the base 1 are used for support, the bracket 5 can be unfolded. After unfolding the bracket 5, the tool lamp can be placed on an uneven workbench surface, ensuring the stability of the tool lamp. When unfolded, the bracket 5 extends from the end of the light source 2 to the support surface, forming a two-point support structure with the base 1, distributing the load pressure on the suspended section of the light source 2.

[0051] Specifically, a second fixing block 9 is provided at the end of the light source 2 away from the base 1. The second fixing block 9 is used to connect the light source 2 and the rotating connector 91. The bracket 5 is rotatably connected to the rotating connector 91. The rotating connector 91 can be implemented by using a connector with a rotating shaft 92. The axis of the rotating shaft 92 is on the same straight line as the axis of the rotating shaft body 811 of the pressure block 81.

[0052] The second fixing block 9 is used to press the metal housing 21 and the light-transmitting lampshade 22 together and achieve a sealed connection. It has a rotating shaft hole suitable for mates with the rotating shaft portion 92. The rotating connector 91 serves as a connecting hub, providing multi-angle support and positioning for the bracket 5 in its unfolded state, and also enabling folding and storage through radial rotation. Specifically, the rotating shaft portion 92 of the rotating connector 91 is coaxially connected to the end of the second fixing block 9, allowing the second fixing block 9 to drive the light source 2 to rotate 360 ​​degrees along the length of the light source 2 on the rotating connector 91. When the projection angle of the light source 2 needs to be adjusted, the second fixing block 9 rotates around the axis on the rotating connector 91. The rotating connector 91 is connected to the bracket 5 via a radial rotating shaft. In the unfolded state, the bracket 5 can unfold around this shaft to a predetermined angle. With two brackets 5, a stable triangular support structure can be formed with the base 1. In the folded state, the bracket 5 rotates around the radial rotating shaft to a position parallel to the light source 2, achieving compact storage. This composite rotational structure, through the synergistic effect of axial and radial degrees of freedom, ensures both support rigidity during unfolding and efficient space utilization during folding. It is important to note that a locking point structure is provided between the rotating connector 91 and the support 5 to limit the maximum rotation angle of the support. By combining the rotating connector 91 and the second fixing block 9 at the end of the light source 2, a dual-degree-of-freedom adjustment mechanism is formed, expanding the support angle range of the support 5 after unfolding and enhancing the overall structural stability through the composite rotational path.

[0053] Through the above technical solution, stable multi-angle support and positioning of the bracket 5 in its unfolded state is achieved, effectively preventing the risk of the lamp falling off due to external force shaking in confined spaces such as the engine compartment. Simultaneously, the composite rotation structure of the rotating connector 91 and the second fixing block 9 allows for axial rotation adjustment of the projection direction of the light source 2, facilitating flexible adjustment of the illumination angle by maintenance personnel according to the inspection location. In the folded state, the bracket 5 is rotated and stored on the side of the light source 2, avoiding damage caused by bumps or knocks during transportation or storage.

[0054] Combination Figure 9 As shown, the light source 2 further includes a metal housing 21, a light-transmitting lampshade 22, and a light-emitting element 23. The light-transmitting lampshade 22 is embedded in the metal housing 21, and the light-emitting element 23 is disposed within the light-transmitting lampshade 22. The metal housing 21 is a structural component used to encapsulate the light source 2 and provide mechanical support. It can be made of aluminum alloy or magnesium alloy, and the heat generated by the light-emitting element 23 is quickly dissipated through a high thermal conductivity material.

[0055] The light-transmitting lampshade 22 refers to the optical component covering the outside of the light-emitting element 23. It can be made of PC or acrylic material and is installed in an embedded manner to form a sealed connection with the metal housing 21, preventing dust from entering and ensuring uniform light diffusion. The two ends of the light-transmitting lampshade 22 are pressed firmly onto the metal housing 21 by the cover plate 82 and the rotating connector 91. The light-emitting element 23 refers to the electronic component that generates illumination. It can be implemented using an LED light panel or a COB light source 2. By being directly fixed inside the light-transmitting lampshade 22, the light propagation path is shortened, reducing light energy loss.

[0056] Specifically, the metal housing 21 provides pressure-resistant support for the light source 2 through its rigid structure, while utilizing its high thermal conductivity to quickly conduct the heat generated by the light-emitting element 23 to the external environment, preventing the light source 2 from having a shortened lifespan due to overheating. The light-transmitting lampshade 22 is assembled by embedding its edges into the metal housing 21. Through its micro-curved surface design, light is scattered during transmission, eliminating the local light spots produced by traditional flat lampshades. The light-emitting element 23 is directly fixed to the inside of the light-transmitting lampshade 22, allowing light to pass through the lampshade without secondary reflection, thereby reducing light loss and improving light extraction efficiency.

[0057] Compared to existing technologies, traditional tool lamps typically use plastic shells for heat dissipation, leading to heat accumulation and easy damage to the light source 2. This solution achieves active heat dissipation through a metal shell 21. Existing lamp shades often use snap-fit ​​assembly, resulting in gaps that allow dust intrusion and light spots. This solution employs an embedded, sealed structure to improve protection. Conventional light-emitting elements 23 are positioned far from the lamp shade, resulting in a long light propagation path and significant energy loss. This solution optimizes luminous efficiency by shortening the distance between the light-emitting element 23 and the lamp shade. This solves the problem of short lifespan of the light source 2 due to insufficient heat dissipation in tool lamps, eliminates dust contamination and uneven light distribution caused by poor lamp shade sealing, and improves lighting efficiency by shortening the light propagation path, ultimately achieving a simultaneous improvement in lamp durability and lighting effect.

[0058] In a preferred embodiment, the distance between the light-emitting element 23 and the light-transmitting lampshade 22 is 2mm to 8mm, preferably 5mm. When the distance is less than 2mm, the heat generated by the light-emitting element 23 cannot be effectively dissipated through air convection, which may cause the light-transmitting lampshade 22 to soften and deform due to heat. When the distance exceeds 8mm, the light will be scattered and lost during transmission due to the excessively long path, and the overall structure of the lamp will have reduced vibration resistance due to excessive internal gaps. This distance range ensures that the air layer between the light-emitting element 23 and the light-transmitting lampshade 22 forms an effective heat dissipation channel, while maintaining the mechanical strength of the lamp housing and preventing internal components from loosening due to vibration.

[0059] The interior of the light-transmitting lamp cover 22 forms a convex structure, and the light-emitting element 23 is fixed inside the light-transmitting lamp cover 22. The distance between the two is precisely controlled by the height of the convexity. For example, when a 5 mm flange is used, a uniform annular heat dissipation gap can be formed between the light-emitting element 23 and the light-transmitting lamp cover 22. Compared with the prior art, traditional automotive repair lamps usually attach the light-emitting element 23 directly to the inner wall of the light-transmitting lamp cover 22, which leads to heat accumulation and accelerated lamp cover aging, or the use of excessively large spacing causes a decrease in light utilization. This solution, by limiting a specific spacing range, avoids the heat conduction problem caused by the contact between the light source 2 and the lamp cover, reduces the light energy waste caused by excessive spacing, and enhances the structural reliability of the lamp in bumpy environments.

[0060] The working principle of this utility model is as follows: When it is necessary to fix the lamp to a metal surface inside the hood or engine compartment of a car, the lamp is attracted by a magnetic array on the bottom cover 6. The magnetic attraction force is precisely calculated to securely fix the lamp without damaging the metal surface. After the lamp is fixed, the user can adjust the angle of the light source 2. The lamp can also be placed at the front of the engine and supported by a bracket, allowing the user to adjust the angle of the light source to illuminate the engine compartment.

[0061] When the lamp is placed on the ground or other non-adhesive surfaces, the base can be opened and placed directly on a level surface. To improve stability, the bracket 5 can be unfolded, supporting the light source 2 and ensuring the lamp's stability. The bracket 5 is designed with the length and weight distribution of the light source 2 in mind, effectively preventing the lamp from tipping over. The lamp can be used hands-free via magnetic adsorption or support by the bracket 5, freeing up maintenance personnel's hands and improving work efficiency.

[0062] In practical applications, the lamp of this invention can be used in multiple ways. For example, when repair personnel need to inspect for faults under the hood of a car, the lamp can be attached to the metal surface inside the hood, and the angle of the light source 2 can be adjusted to achieve localized illumination. It can also be placed at the front of the engine and supported by a bracket, with the angle of the light source adjusted to illuminate the engine compartment; since the lamp does not need to be manually held, repair personnel can focus on repair operations, significantly improving work efficiency.

[0063] When the luminaire is used in a floodlight scenario, the user can place the luminaire on the ground and unfold the bracket 5 to support the light source 2, ensuring the stability of the luminaire. Of course, if the ground is relatively flat, the bracket is not required, and only the bottom cover needs to be opened for support. In addition, the luminaire also supports a brightness adjustment function, allowing the user to adjust the brightness of the luminaire according to the ambient light conditions, avoiding excessively strong or weak light from affecting maintenance operations.

[0064] In summary, this utility model, through innovative structural design and functional optimization, provides a highly efficient, stable, and safe handheld tool lamp, particularly suitable for engine compartment lighting in automotive repair scenarios. This lamp solves many problems in existing technologies, significantly improving repair efficiency and user experience, and has broad market application prospects.
