An upper portion (14) of a base (10) has LED chips (12) arranged in two groups (24,26), such that one group of LED irradiates specific region of dental restoration material and another group of LEDs irradiates a different region of dental restoration material. The two groups of LEDs are controlled to irradiate their respective regions of dental restoration material independently.
