triac dimmable led in Light curing machine

LED lights curing machine is used in the clinic with triac dimmable led, dentistry and other light-curing resin is cured, for dental repair teeth.   Ordinary light sources produce light with ultraviolet, infrared and visible light. UV energy, infrared light is easily absorbed by the object, they can easily be irradiated to the object heats up, so, generally in addition to ultraviolet and infrared light, only visible light beam called cold light. But we know that the light itself is a kind of energy, they can be irradiated to the object heats up, so the light curing unit, I think the light on the photosensitive resin (such as 430-480nm) is called luminescence more appropriate. The LED light curing machines, compared with halogen lamps, heat is much smaller, and the light almost all Blu-ray, so that it is cold. However, some curing machines use high-power LED street lights, on one hand, its high light intensity, such as the above 1000mW/cm2, on the other hand, in order to obtain such a large light intensity, must be designed to maximize the drive current, up to 1000-2000mA, resulting in a larger LED heat, issued by the broadening of the spectral range, so that it will also make the resin temperature rises, such LED light curing machines are not completely cold. When you purchase a light side alignment palms, the irradiation light mode palms feeling the temperature rise to determine, we should appropriate to the palm of the hand is not too hot. Excellent curing effect, of course, completely luminescent LED light curing unit with triac dimmable led, is being more and more doctors recognize. LEDs can be divided into two categories: special high-brightness LEDs and high power LED high bay lights. High-power LEDs emit light intensity is higher, some single LED could be strong up to 700 or even 1000mW/cm2, but compared with the traditional ones, its wide spectral range, but also a certain degree of fever.As discussed previously, the super high brightness LED light almost 100% light, but for a much wider spectral range of high-power LED like triac dimmable led, usually 410-510nm visible, it also has many non-effective light can be seen from two who spot the thermal contrast visually determine from the cured resin temperature rise test out. Of course, due to the high light intensity, high-power LED light curing unit, curing time is much shorter, usually 10-15 seconds, which can reduce the operating hours of doctors, doctors lighter.In addition, if you are using a photosensitive resin sensitive wavelength is special, then you should use a high-power LED light curing machine.
