Background Of The Curing Lights

In the field of tooth restoration and repair, dental cavities are often filled or sealed with compounds that are photosensitive, either to visible or ultraviolet light. These compounds, commonly known as light-curable compounds, are placed within dental cavity preparations or onto dental surfaces and are cured when exposed to light from a dental curing light device.
In addition, multiple light sources used in making a dental equipment capable of multiple wavelengths may further add to excessive heat generation problems if the light sources generate a wide spectrum of light, leading to more heat that needs to be diverted away from the dental autoclave sources. Even with light sources generating just the desired wavelength for composite curing, heat generation is still a problem. Consequently, elaborate cooling systems are needed to handle heat, possibly creating a large, heavy and expensive LED curing light.
Also, for devices with multiple wavelengths, if more light intensity is generated for one wavelength as compared to a second wavelength at the same power input, unless separate power supplies are used, or power is diverted away in some fashion, the excessive intensity at one wavelength may also lead to excessive heat at the point of generation. Accordingly, there remains a need for a new device that can solve the problems listed above.
