The present invention provides a light-curing unit, comprising an LED having two or more light-emitting chips for emitting light in different respective wavelength ranges among wavelength ranges for curing photopolymers so that the LED emits light in a wavelength range of 400 nm to 500 nm; a power source for supplying electric power to the LED; and a housing formed to take the shape of a rod that can be introduced into the mouth of a person so as to limit the position and light-emitting direction of the LED. With the use of the LED and the light-curing unit using the same according to the present invention, there are advantages in that it is possible to cure (light cure) all photopolymers that are light curable at different wavelengths, expenses for purchase and management of equipment can be reduced, and convenience can be ensured since the LED and the light-curing unit can be used in common regardless of the kinds of photopolymers. |
