Wireless LED Light Curing Unit
The utility model discloses an LED multifunctional light curing machine, which comprises a host, a light emitting device and a lithium battery are arranged in the host, and the special warfare is that the light guide rod is arranged at the end of the host. By converting the light guide rod can be used to achieve blue light curing, white light for internal oral lighting, to achieve a multi-purpose machine.
Light intensity analysis
Light curing unit used in the LED, compared with the halogen lamp, its heat is much smaller, and the light is almost blue, so it is cold.
LED light curing unit is not as high as the light intensity. Expert studies have shown that the mechanical strength of the light-cured photosensitive resin is related to the amount of cross-linked long-chain macromolecules in the resin. The greater the number, the better the mechanical properties. If too high a light intensity is used, the molecules in the resin will not cure and will not flow for a long time. As a result, a large number of short-chain molecules will be produced, resulting in a higher internal shrinkage stress of the resin and a decrease of the mechanical properties. At the same time, Easy to produce cracks. The recommended method should be the use of weak light guidance, the initial low light intensity is conducive to the movement of molecules in the resin is conducive to the formation of long-chain macromolecules, and then quickly cured with high light intensity in order to achieve the best curing effect. After a large number of tests show that the light intensity of LED curing light, especially bright LED 200 mW / cm 2 above, high-power LED 500 mW / cm 2 above, you can achieve better than ordinary halogen curing machine curing effect .
