1、 Product Design Proposal: Exclusive Torque Insertion Type One Word Damping Structure for LED Desk Lamp

The LED desk lamp features an ultra-thin body, simple appearance, lightweight structure, and a narrow internal cavity. It has extremely high requirements for the volume, damping uniformity, concealed installation, and noise reduction effect of the rotating shaft. Traditional exposed damping shafts have a large volume, are prone to dust accumulation, have unstable torque, and are prone to wear and jamming, making them unsuitable for high-end LED lighting fixtures. Our factory has undergone a brand new upgradeTorque insertion type built-in damping structureThe damping friction component is fully embedded and packaged, with a more compact structure, stable performance, and stronger adaptability. It is currently the mainstream standard structure for high-end LED eye protection desk lamps and internet famous folding lamps.

Built in torque core design (exclusive advantage)Adopting a shaft core with built-in damping torque insertion structure, the damping friction component is completely enclosed inside the shaft body, without exposure, dust accumulation, or impurities. Compared with traditional exposed damping structures, it effectively eliminates the problems of lagging, jamming, and damping failure caused by dust entering. The torque output is uniform and linear throughout the entire process, and there will be no new shaft tightening or long-term slipping. The long-term use feels consistent and perfectly adapts to the long-term high-frequency dimming and folding storage conditions of LED desk lamps.

Ultra thin and lightweight single word microstructure designAdopting an integrated straight through hinge design with no extra protrusions or external accessories, the body is micro and ultra-thin, specially tailored for narrow arms and thin machine bodies of LED desk lamps. It can be fully embedded and concealed, without top shell, bulging, or damaging the appearance flow of the lamp. It is compatible with plastic, aluminum alloy, and metal lamp body shells, and is compatible with high-speed assembly on automated assembly lines. The assembly is simple and the yield rate is high, which fits the minimalist and luxurious design style of modern LED desk lamps.

360 ° seamless stop, anti fall and anti shake structureSupports horizontal 360 ° infinite rotation and multi angle dimming with up and down pitch, without any jamming, jerking, or angle restrictions throughout the entire process. Built in precision torque locking module, achieving true stepless self-locking, stop immediately upon release, precise locking at any angle, without rebound, falling, or shaking. Thoroughly solve the problems of light weight of LED desk lamp head, unstable support of conventional shaft, long-term static lowering, light deviation, touch movement, etc., and accurately hover from multiple angles to meet the dimming needs of learning, office, reading, and beauty scenes.

Precise torque adjustable designBased on the advantage of the embedded torque structure, it supports precise torque adjustment calibration and can be matched and adapted to damping force one-to-one according to the length of the LED desk lamp arm, the weight of the lamp head, and the number of cantilever layers. Effectively solves the common problems of excessive torque and stiff angles in ordinary shafts, as well as insufficient support due to low torque. It is suitable for all types of lamps, including mini desk lamps, long arm folding lamps, and multi section cantilever LED fill lights. It is compatible with new private model research and development and old lamp upgrades.

Closed anti attenuation and silent structureThe embedded fully enclosed structure can effectively protect the internal damping components, isolate dust and water vapor intrusion, and with pre pressure locking technology, the damping bite is tight and uniform, and the anti attenuation and anti fatigue performance are greatly improved. Even after tens of thousands of folding, angle adjustment, and rotation storage, it remains silent and stable in torque, without any dry or abnormal noise, slipping or loosening. The length, aperture, installation hole spacing, and limit angle of the shaft can be customized according to needs, suitable for large-scale standardized production.

2、 Material process: precision, high strength, fine, wear-resistant, rustproof and anti-aging

For the long-term use of LED desk lamps in home work, bedrooms and study rooms, humid and dusty conditions, frequent folding and dimming, daily hand friction, and long-term static pressure, this one word damping hinge is carefully selectedHigh toughness precision industrial carbon steel materialHigh end models can be optionally equipped with 304 stainless steel material. The material is dense and pure, with moderate hardness, excellent deformation resistance, wear resistance, fatigue resistance, and oxidation resistance. It meets the national standards for small household appliances and 3C digital environmental protection testing, and solves common quality problems such as rusting, deformation, fast damping attenuation, lagging noise, and short service life of micro lamp shafts from the root.

Integrated CNC precision machining processA single axis body, an embedded damping chamber, and an integrated precision molding for installation and positioning, with no splicing gaps or welding breakpoints. The overall structure has high concentricity and sufficient rigidity. Eliminate defects such as eccentricity, loosening under stress, cracking, and deformation of ordinary welding shafts. Long term repeated folding, rotation, and dimming will not deform or shake, ensuring that the adjustment feel of LED desk lamps is delicate, uniform, and smooth at the high end.

Micro scale hardening and precision grinding process for damping surfaceThe internal embedded damping friction plate adopts high-frequency quenching and hardening+micrometer level precision grinding treatment, with a smooth and burr free friction surface, precise and controllable fit clearance, linear and soft torque output, no mechanical hard impact, and no sudden tightening or loosening phenomenon. The dimming and folding of the desk lamp are completely silent and soft, without any metal friction or abnormal noise, greatly enhancing the overall texture and grade of the high-end LED eye protection desk lamp.

Multiple anti-corrosion and rust prevention processes for household appliancesThe surface is treated with thickened environmentally friendly electroplating and passivation sealing composite rust prevention, with a thick and uniform coating, strong adhesion, and less likely to peel off. It can effectively isolate moisture, air dust, and hand sweat corrosion at home, and prevent the shaft from blackening, rusting, jamming, and rotation failure. It has excellent moisture-proof, rust proof, and anti-aging properties, and has a new appearance and stable performance for long-term indoor use.
