Low-temperature and high-intensity LED light curing

The new low-temperature and high-intensity LED light curing machine from DYM is a device that uses a specific wavelength of LED light source to irradiate light-curable materials (such as resins, glues, inks, etc.) to cause photochemical reactions and thus quickly cure. Its core principle is based on blue light-induced polymerization reactions to achieve high-efficiency, energy-saving, and rapid curing. It mainly involves the following key links:
I. Basic principles of light curing
(1) Composition of light-curable materials
Light-curable materials (such as UV resins) usually contain:
Oligomers: provide mechanical properties after curing (such as hardness and flexibility).
Active monomers: adjust viscosity and reaction speed.
Photoinitiator: absorbs light energy of a specific wavelength, generates active free radicals or cations, and initiates polymerization reactions.
Additives (such as pigments, leveling agents, etc.).
(2) Photoinitiation process
When ultraviolet (UV) or visible light (usually with a wavelength of 365nm, 385nm, 395nm, 405nm, etc.) emitted by an LED light source irradiates the surface of the material, the photoinitiator absorbs the photon energy, breaks chemical bonds, and generates free radicals or cations.
These active groups trigger the chain polymerization reaction of monomers and oligomers, causing the liquid material to solidify into a solid state within a few seconds to a few minutes.
II. Characteristics of LED light sources
Compared with traditional mercury lamps, the advantages of LED light curing machines are:
Accurate wavelength: LED emits a narrow spectrum (±10nm), which can match the optimal absorption peak of the photoinitiator and is more efficient.
Instant switch: No preheating is required, it lights up when the power is turned on and stops when the power is turned off.
Energy saving and environmental protection: low energy consumption (only 10%-30% of mercury lamps), no mercury pollution, and long life (about 20,000-50,000 hours).
Low thermal radiation: Reduce thermal damage to the cured material (especially suitable for heat-sensitive substrates)
III. Key components of the curing machine

1. LED light source module:
   Use high-power UV-LED chips (such as 365nm/395nm) with lenses or reflectors to focus light.
   Multi-lamp array design to ensure uniform irradiation.
2. Cooling system:
   Control the LED temperature through fans, heat sinks or water cooling systems to avoid light decay.
3. Control system:
   Adjust the light intensity (irradiance, unit: mW/cm²) and exposure time (seconds) to adapt to different material requirements.
   Some equipment is equipped with smart sensors to automatically detect the degree of curing.
4. Mechanical structure:
   Designed as handheld, desktop or conveyor type (such as 3D printing post-curing box) according to the application scenario.
   IV. Usage scenario:
   3D printing: curing photosensitive resin (such as SLA, DLP technology).
   Electronics industry: curing UV glue (such as mobile phone screen bonding, circuit board packaging).
   Printing and coating: UV ink, coating curing (such as packaging printing, furniture paint).
   Dental care: dental filling material curing, medical adhesive bonding
   The core of LED light curing machine is to achieve efficient and energy-saving rapid curing through precise wavelength LED light source to excite photoinitiator. Its technical advantages have promoted the innovation of 3D printing, electronic manufacturing and other fields. In the future, with the increase of LED power and the diversification of wavelength (such as deep ultraviolet LED), the application scope will be further expanded. When using, it is necessary to optimize the lighting parameters according to the material characteristics to achieve the best curing effect.
   The new model of Duoyimei low-temperature and high-illuminance light curing machine is launched, providing efficient work for dentists in dental clinics, oral hospitals, oral teaching and other places.
   The high-definition LED display can digitally display the light intensity in any case, and the specific mode can adjust the light intensity to achieve intelligent light control low-temperature filling, which is non-sensitive and non-irritating.
   The selected 10MM light guide rod has a wider repair area and higher efficiency than the 8MM light guide rod on the market. Optional orthodontic special light guide rod has better focusing effect, stronger penetration and higher efficiency.
   In low power conditions, the light intensity does not decay.
   Super standby, in strong light mode, calculated as 3s, one charge can be used 800-1000 times.
   Eight modes can be switched freely, super mode, strong light mode, standard mode, pulse mode, progressive mode, inspection mode, orthodontic mode, comfort mode;
   Metal aluminum alloy shell, sturdy and durable, 4 fashionable colors available (bright gold, violet, sapphire blue, mountain gray);
   Rechargeable and built-in two types are available.
   2-year warranty for the whole machine (excluding light guide rod), lower cost of use
   One city, one agent, effectively improve core competitiveness
