[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0028] As attached Figures 1 to 9 The energy-saving and environmentally friendly LED lamp shown includes a lamp housing 101, which serves as the load-bearing and protective main body of the entire lamp. It is manufactured using a die-cast aluminum alloy process, and its internal cavity design helps optimize airflow. The inner surface of the housing 101 is covered with a special high-emissivity coating, which significantly improves heat radiation efficiency. A ring-shaped reinforcing rib at the bottom is integrally formed with the housing 101, effectively preventing deformation under stress. The light-transmitting cover 102 is connected to the right side of the housing 101 via a multi-point symmetrically distributed snap-fit ​​structure, ensuring uniform stress distribution. The sealing ring 103 is made of high-temperature resistant silicone material, and its labyrinthine sealing structure includes multi-level sealing lips, effectively blocking dust and moisture. The heat dissipation holes 104 are specially designed to form convection channels on the top and left side of the housing, and a removable dustproof mesh installed on the inner side facilitates maintenance and cleaning.

[0029] The optical system employs a composite structure: the substrate 105 uses UV-resistant polycarbonate as the base material, with special particles injected to improve light transmittance; the prism layer 106 forms a microprism array on the inner surface of the substrate 105 through precision processing, and optimizes the light distribution curve using a total internal reflection design; the protective film 107 adopts a multi-layer composite structure, including a UV-resistant layer, an anti-glare layer, and a hydrophobic layer, giving the surface self-cleaning properties. The LED light source board 2 uses a special substrate 105, which achieves close contact with the thermally conductive connecting plate 402 through a high thermal conductivity adhesive.

[0030] The mounting system uses an aluminum alloy cast base 301 with anti-slip textured bottom. A precision bearing is installed inside the rotating shaft 302 to ensure smooth and accurate rotation. The angle dial 303 uses a wear-resistant substrate 105 with clearly legible laser-engraved graduations, and the built-in indicator light automatically adjusts its brightness.

[0031] The fixed bracket 401 of the thermo-actuated dimming system 4 adopts a space truss structure, which has been carefully optimized. The surface of the heat-conducting connection plate 402 is coated with a special coating, significantly enhancing heat conduction performance. The lens bracket 408 of the reflector assembly 403 is made of aerospace-grade aluminum alloy, possessing a high strength-to-weight ratio. The reflector lens 409 adopts a parabolic design, with its surface coated with a high-reflectivity material. The counterweight 410 is made of high-density alloy material, enabling precise counterweight adjustment. The limiting post 411 incorporates a hydraulic buffer device, effectively absorbing impact energy.

[0032] The first heat-deformation plate 405 of the thermally sensitive actuator 404 is made of bimetallic composite material and has high thermal sensitivity. The second heat-deformation plate 406 adopts a special amplification mechanism, and the connecting arm 407 adopts a variable cross-section design to achieve lever ratio adjustment. The heat dissipation system includes specially shaped heat dissipation fins 412, and the surface treatment helps to improve heat dissipation efficiency. The guide channel 413 adopts an aerodynamic design, and the airflow hole 414 adopts a special structure to improve airflow velocity.

[0033] The heat sink assembly 501 of the auxiliary cooling device 5 features an optimized design, providing ample heat exchange area. The heat-conducting plate 502 has an embedded temperature-equalizing cavity, enabling efficient heat distribution. The fan 503 employs an advanced bearing system, ensuring a long service life.

[0034] The gravity block 601 of the safety protection system features an adjustable center of gravity design for precise adjustment. The guide rail 602 uses a precision guide rail to ensure accurate movement. The protective cover 603 employs a special structure for quick deployment to provide protection. The permanent magnets 701 of the magnetic-assisted adjustment system 7 use a special arrangement to provide a strong magnetic field. The electromagnetic component 702 uses a high-efficiency heat dissipation system to ensure stable operation. The adjustment switch 703 uses touch control for precise and convenient operation.

[0035] Specifically, when the LED light source board 2 is working, the heat generated is quickly conducted to the thermally sensitive driving component 404 through the heat-conducting connecting plate 402. The first heat-deformation sheet 405 undergoes precise bending deformation due to heat, and the deformation is amplified and transferred to the second heat-deformation sheet 406 through the lever action of the connecting arm 407. The second heat-deformation sheet 406 undergoes coordinated deformation, thereby driving the lens bracket 408 to deflect. On the one hand, this causes the reflective lens 409 to change the light reflection angle, realizing intelligent stepless dimming without external power. On the other hand, the deflection of the lens bracket 408 simultaneously drives the heat dissipation fins 412 to disturb the surrounding air and form forced convection. Under the optimization of the airflow guide groove 413 and the acceleration of the airflow hole 414, the airflow forms a high-efficiency heat dissipation channel linked to the dimming action, realizing intelligent coordination of light and heat management.

[0036] When the lamp accidentally tilts, the gravity block 601 slides rapidly along the guide rail 602 under the action of gravity, causing the protective cover 603 to quickly unfold to cover the light-transmitting cover 102, preventing direct strong light from causing danger and achieving passive safety protection. Users can control the magnetic strength or polarity of the electromagnetic component 702 by adjusting the switch 703, using magnetic force to attract or repel the permanent magnet 701, thereby assisting in adjusting the deflection angle of the reflector assembly 403, thus achieving artificial intervention in optical path optimization and completing precise fine-tuning of the performance of the entire lighting system. Example 2

[0037] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 9 As shown below, see details: Furthermore, a heat conduction enhancement layer is provided between the first heat deformable sheet 405 and the heat-conducting connecting plate 402. This heat conduction enhancement layer is made of a high thermal conductivity material to ensure rapid heat transfer. The free end of the second heat deformable sheet 406 is rigidly connected to the top of the lens support 408 of the reflector assembly 403 to ensure power transmission efficiency. The two ends of the connecting arm 407 are connected to the first heat deformable sheet 405 and the second heat deformable sheet 406 respectively through hinge shafts. Rolling bearings to reduce friction are installed at the hinge shafts. When the first heat deformable sheet 405 is heated and undergoes bending deformation, the deformation is amplified and transmitted to the second heat deformable sheet 406 through the lever action of the connecting arm 407. After receiving the deformation force, the second heat deformable sheet 406 undergoes synchronous bending deformation and directly drives the lens support 408 to perform precise deflection motion around its rotation axis. A balancing component to maintain structural balance is also provided between the first heat deformable sheet 405 and the second heat deformable sheet 406. This balancing component includes an adjustable counterweight 410 and a balance... The spring and connecting arm 407 have a precision adjustment mechanism in the middle that can adjust the position of the connection point. The position of the connection point can be changed by rotating the adjusting screw, thereby adjusting the transmission ratio between the first heat-deformable sheet 405 and the second heat-deformable sheet 406. A mechanical limiting structure is provided at the end of the second heat-deformable sheet 406 to limit its maximum deformation. The limiting structure includes a limiting block and a buffer pad. At the same time, a temperature compensation layer is covered on the surface of the first heat-deformable sheet 405 to reduce the influence of ambient temperature fluctuations. All connections are equipped with anti-loosening fastening devices to ensure connection reliability. Deformation guide grooves are also opened on the surfaces of the first heat-deformable sheet 405 and the second heat-deformable sheet 406 to control the deformation direction. A strength reinforcing rib is added to the connecting arm 407 to improve structural rigidity. A dustproof protective cover 603 is installed around the entire thermal drive component 404. A scale indicator for displaying the deflection angle is provided at the connection between the second heat-deformable sheet 406 and the lens holder 408. Lubricating grease is added to the hinge shaft to maintain smooth movement.

[0038] Furthermore, the lens holder 408 is made of lightweight, high-strength aluminum alloy. Its top end is rigidly connected to the free end of the second heat-deformation sheet 406. The reflective lens 409 is fixed to the lower surface of the horizontal short arm of the lens holder 408 via an adjustable-angle mounting base. Locking screws are provided around the mounting base 3 to fix the angle of the reflective lens 409. The counterweight 410 is located on the bottom left side of the vertical part of the lens holder 408 and its position on the lens holder 408 can be adjusted by the counterweight adjustment bolt. The limiting posts 411 are symmetrically arranged on the front and rear sides of the rotation trajectory of the vertical part of the lens holder 408. The surface of the limiting posts 411 is covered with elastic cushioning material. When the lens holder 408 is deflected by the second heat-deformation sheet 406, the counterweight 410 moves accordingly. The counterweight 410 acts as a balance for the lens holder 408. The moment of inertia of the lens holder 408 can be changed by adjusting the position of the counterweight 410. When the lens holder 408 deflects to its limit position, its vertical part contacts the limit post 411 and absorbs the impact energy through the elastic buffer material to prevent structural damage. A high-precision rolling bearing is installed at the rotation axis of the lens holder 408 to ensure smooth rotation. The surface of the reflective lens 409 is coated with a high reflectivity film to improve light efficiency. The lens holder 408 is also equipped with a handle structure for easy installation and maintenance. A scale indicator for displaying the deflection angle is set at the connection between the lens holder 408 and the second heat-deformation sheet 406. High-temperature grease is added to the rotating joint to ensure the reliability of movement in a hot environment.

[0039] Furthermore, heat dissipation fins 412 are disposed on the vertical rod of the lens support 408, and their surfaces are anodized to enhance heat radiation efficiency. Multiple sets of heat dissipation fins 412 are arranged parallel to each other along the vertical rod of the lens support 408 to form a heat dissipation array. Equal spacing is maintained between adjacent heat dissipation fins 412 to ensure smooth airflow. A guide groove 413 is disposed between every two heat dissipation fins 412 and has a streamlined cross-section to optimize the airflow path. An airflow hole 414 is disposed through the vertical rod of the lens support 408 and is connected to the guide groove 413 to form a complete airflow channel. When the lens support 408 is heated and deflects, the heat dissipation fins 412 move with the support and agitate the surrounding area. The airflow is guided by the flow channel 413 to flow in a specific direction to enhance the convective heat transfer effect. The airflow hole 414 promotes the formation of convective circulation of air inside the lens holder 408. The edge of the heat dissipation fin 412 is provided with a serrated structure to increase the heat dissipation area. The inner surface of the flow channel 413 is processed with raised textures to promote turbulence. The inlet and outlet of the airflow hole 414 are provided with a filter screen to prevent foreign objects from entering. The surface of the heat dissipation fin 412 is coated with a special coating to improve the thermal emissivity. The lens holder 408 is embedded with a temperature sensor to monitor the heat dissipation effect in real time. Through the synergistic effect of the heat dissipation fin 412, the flow channel 413 and the airflow hole 414, the operating temperature of the lens holder 408 is reduced.

[0040] Furthermore, the outer casing 101 is made of die-cast aluminum alloy and has a special coating on its inner surface to enhance heat radiation. The light-transmitting cover 102 is installed on the right side of the outer casing 101. The sealing ring 103 is made of high-temperature resistant silicone material and is installed in the joint groove between the casing and the light-transmitting cover 102 with an interference fit. The heat dissipation holes 104 are located on the top and left side of the outer casing 101. When the internal temperature of the lamp housing 1 rises, heat is conducted through the casing material to the area of ​​the heat dissipation holes 104. The heat dissipation holes 104 promote air convection and form a bottom-up heat dissipation airflow channel. The sealing ring 103 forms a double sealing barrier between the casing and the light-transmitting cover 102 to effectively prevent dust and moisture from entering. The edge of the light-transmitting cover 102 has a sealing groove structure that precisely matches the sealing ring 103 to ensure sealing reliability. The inner side of the heat dissipation holes 104 is provided with a multi-layer dust filter to prevent foreign objects from entering the casing. The bottom of the outer casing 101 is provided with a radial reinforcing rib network to enhance structural strength. The connection between the light-transmitting cover 102 and the outer casing 101 is provided with a visual indicator mark to show the connection status. The surface of the sealing ring 103 is coated with high-temperature resistant grease to ensure smooth installation. The heat dissipation hole 104 adopts an involute design to make the airflow more stable. Inside the outer casing 101, corresponding to the position of the heat dissipation hole 104, there is a guide rib to optimize the airflow path. The light-transmitting cover 102 is made of high light transmittance polycarbonate material and has a microprism structure on the inner surface to improve light distribution. The sealing ring 103 adopts a double lip design to enhance the sealing effect. The edges of the heat dissipation hole 104 are rounded to prevent the airflow from generating eddy noise. Through the coordinated cooperation of the outer casing 101, the light-transmitting cover 102, the sealing ring 103 and the heat dissipation hole 104, both the sealing and protection performance of the lamp and the efficient heat dissipation effect are ensured.

[0041] Furthermore, the substrate 105 is integrally molded from high-transmittance polycarbonate material using a precision injection molding process. Its outer surface undergoes nano-level optical polishing to reduce light scattering loss. The prism layer 106 forms a uniformly distributed microprism array structure on the inner surface of the substrate 105 using a precision hot-pressing process. Each microprism unit employs a total internal reflection optical design to optimize light distribution. The protective film 107, using a multi-layer composite structure, is coated onto the outer surface of the substrate 105 using a vacuum coating process. It includes an anti-UV layer, an anti-glare layer, and a wear-resistant layer. When light passes through the protective film 107 into the substrate 105, the anti-UV layer effectively filters harmful radiation, the anti-glare layer eliminates glaring spots, and the light reaches the prism layer 106 after total internal reflection within the substrate 105. The microprism array precisely controls the refraction and reflection of the light to achieve a specific light distribution curve. The edge of the substrate 105 is provided with a connection to the lamp housing 1. The system features a quick-release snap-fit ​​structure with a sealing groove at the joint. The protective film 107 extends to the side of the substrate 105 using ultrasonic welding to form a comprehensive protective coating. The prism layer 106 and the substrate 105 are seamlessly bonded together using optical-grade adhesive, and a gradient refractive index material is used at the interface to eliminate Fresnel reflection. An anti-reflection film is also provided on the inner surface of the substrate 105 to further improve light transmittance. The outer surface of the protective film 107 is treated with antistatic and oleophobic agents to prevent dust adsorption and stain residue. Anti-UV stabilizers and anti-aging agents are added inside the substrate 105 to extend its service life. The substrate 105 provides the main structural support and light transmission medium, the prism layer 106 enables precise optical control, and the protective film 107 provides comprehensive surface protection. The synergistic cooperation of these three components ensures that the light-transmitting cover 102 maintains high light transmittance while possessing excellent environmental resistance and optical performance.

[0042] Furthermore, the heat sink assembly 501 is disposed on the outer top surface of the lamp housing 1. One end of the heat conduction plate 502 is connected to the back of the LED light source board 2, and the other end is connected to the bottom of the heat sink assembly 501. The fan 503 is disposed between the heat sink assemblies 501. When the LED light source board 2 is working, the heat generated is quickly conducted to the heat sink assembly 501 through the heat conduction plate 502. The heat sink assembly 501 exchanges heat with the air by increasing the heat dissipation area. After the fan 503 is started, it generates forced convection airflow to accelerate the airflow through the channels between the heat sink assemblies 501. The heat conduction plate 502 and the heat sink assembly 501... The welding method ensures efficient heat conduction. The surface of the heat sink assembly 501 has a corrugated structure to increase turbulence. The fan 503 automatically adjusts its speed according to the temperature sensor signal to achieve intelligent temperature control. A heat pipe structure is set at the bottom of the heat sink assembly 501 to enhance the lateral heat diffusion capability. The inlet and outlet of the fan 503 are equipped with dustproof nets and air guides to optimize airflow distribution. The heat sink assembly 501 provides the passive heat dissipation basis, the heat conduction plate 502 achieves efficient heat conduction, and the fan 503 provides active heat dissipation power. The synergy of the three ensures that the lamp can maintain a suitable operating temperature when working at high power.

[0043] Furthermore, the base 301 is disposed on the bottom outer surface of the lamp housing 1, the rotating shaft 302 connects the base 301 to the bottom of the lamp housing 1, and the angle disc 303 is disposed on the rotating shaft 302. When the lighting angle needs to be adjusted, the rotating shaft 302 is rotated within the base 301 by rotating the lamp housing 1. The ball bearings inside the rotating shaft 302 ensure smooth and stable rotation. The angle disc 303 rotates synchronously with the rotating shaft 302 and indicates the current angle position via a fixed pointer. The base 301 is securely fixed to the mounting surface by multiple expansion bolts. A quick-locking mechanism for locking the angle is provided at the connection between the rotating shaft 302 and the lamp housing 1. The surface of the angle disc 303 is covered with... The base 301 features a scratch-resistant transparent protective layer and a concealed cable channel for orderly power cord routing. The rotating shaft 302 incorporates an adjustable damping mechanism for stepless angle adjustment and arbitrary positioning. The angle dial 303 has luminous markings on its edge for accurate reading in dark environments. A waterproof sealing ring is also provided at the connection between the rotating shaft 302 and the base 301 to prevent moisture intrusion. The base 301 provides a stable mounting foundation, the rotating shaft 302 enables flexible and reliable angle adjustment, and the angle dial 303 provides clear and accurate angle indication. The coordinated operation of these three components allows the lamp to be quickly and accurately adjusted to the desired lighting angle and remain stable.

[0044] Furthermore, the gravity block 601 is slidably mounted on the vertical guide rail 602 on the inner wall of the back of the lamp housing 1. The protective cover 603 is connected to the bottom of the gravity block 601 via a connecting rod. When the lamp is tilted, the gravity block 601 slides along the T-shaped groove of the guide rail 602 under the action of gravity. The movement of the gravity block 601 drives the protective cover 603 to move along the guide rail via a linkage mechanism. Buffer blocks that limit the movement range of the gravity block 601 are provided at both ends of the guide rail 602. The protective cover 603 and the gravity block 601 are connected by a universal joint to accommodate tilting at different angles. The system is equipped with a ball bearing guide rail system to reduce the coefficient of friction. The gravity block 601 has a position sensor embedded inside to detect the movement.

The gravity block 601 provides gravity sensing power, the guide rail 602 ensures directional movement, and the protective cover 603 realizes the protection function of the light-transmitting cover 102. The coordinated operation of the three enables the lamp to automatically trigger the protection mechanism when it tilts.

[0045] Furthermore, the permanent magnet 701 is mounted on the vertical rod of the lens holder 408, and the electromagnetic component 702 is correspondingly mounted on the fixed bracket 401. The adjustment switch 703 is located on the outer surface of the lamp housing 1. When the user rotates the adjustment switch 703, the control circuit precisely adjusts the magnitude and direction of the current passing through the electromagnetic component 702 according to the rotation angle and speed signal. The electromagnetic component 702 generates a controllable magnetic field of corresponding strength and polarity according to the current change. Under the action of the magnetic field, the permanent magnet 701 experiences precise attraction or repulsion. This magnetic force is converted into driving torque through the lens holder 408, thereby precisely controlling the deflection angle of the reflector assembly 403. The electromagnetic component 702 is externally equipped with a magnetic shield made of high-permeability material to prevent magnetic field interference with other electronic components. An optimal air gap distance is maintained between the permanent magnet 701 and the electromagnetic component 702, and this is monitored in real time by a distance sensor to ensure... The magnetic force efficiency is enhanced by the adjustment switch 703, which features intermediate zero position and stepless forward / reverse adjustment with tactile feedback. An embedded temperature sensor within the electromagnetic component 702 monitors coil temperature rise in real time and is equipped with overheat protection. The control circuit employs a PID algorithm for precise current control. A stable magnetic field source is provided by the permanent magnet 701, and the electromagnetic component 702 generates a precisely controllable adjustment magnetic field. The adjustment switch 703 enables fine-tuning control. The coordinated operation of these three components allows users to precisely fine-tune and compensate for the deflection angle of the reflector assembly 403. A position feedback sensor is installed on the lens holder 408 to form a closed-loop control system. The electromagnetic component 702 is equipped with heat sinks 412 to ensure long-term operational stability. The adjustment switch 703 features a digital display screen that shows adjustment parameters in real time. The entire system employs an anti-interference design to ensure reliable operation in complex electromagnetic environments.
