How to choose LED light source for dental curing light?
Dental curing light is an oral device for repairing teeth. It uses the principle of light curing to rapidly cure dental resin materials under the action of light waves within a specific wavelength range, thereby filling tooth cavities or bonding brackets. Oral materials require a special kind of light to cure, that is, solidify. Therefore, a light curing machine is a machine used to provide light to solidify light-curing materials.
Dental light curing machines can be divided into LED light curing machines and halogen light curing machines
LED light curing machines are commonly used in the market now, because the wavelength of light emitted by LED is concentrated around 430-480nm, which is the sensitive wavelength of light-cured resin. The LED light source specially developed by Silver Moonlight Technology for dental light curing machines has a peak wavelength of 460nm. Since there is no other stray light, more than 90% of the energy is converted into pure blue light energy, and almost no excess heat is generated. Halogen bulbs have a wide light spectrum, and only 0.7% of the blue light energy is useful. All seven colors of light are converted into heat energy, generating local high temperatures, causing the cured resin to fall off easily. Therefore, the market is now mainly LED light curing machines.
The appearance of LED light curing machines varies, but the structures are basically the same, namely: light guide rod, light curing shield, LED lamp, electronic controller, battery and power supply.
How to choose LED light source for dental light curing machine?
The structure of light curing machine is relatively simple, and the key role is LED lamp and light guide rod, followed by the quality of electronic controller.
The LED light of a good light curing machine must have a narrow wavelength error range, and the best is cold light (blue light) of 450nm-480nm; the LED light source specially developed by Yinyueguang Technology for dental light curing machine has a wavelength peak of 460nm and a 395nm band, which makes dental repair resin materials cure quickly under the action of light waves, and is the best LED light source choice; secondly, LED lamp can maintain the original light intensity under long-term operation; thirdly, it has a strong light intensity under low color temperature.
