A photo-curing device (100) comprises a light source (111) for initiating the curing of a photo-curable material. The light source (111) comprises light-emitting diodes (LED1-LED4), each emitting light in a determined wavelength range, the wavelength ranges of the LEDs overlapping partially so as to cover a continuous wavelength range that is broader than the wavelength range of each LED. The photo-curing device also includes activation means (120) for selectively activating each LED (LED1-LED4).本發明係關於一種光硬化裝置(100)，其包含用於誘發光可硬化材料硬化之光源(111)。該光源(111)包含各放射確定波長範圍光之發光二極體(LED1至LED4)，該等LED之波長範圍部份重疊以涵蓋較各LED之波長範圍寬之連續波長範圍。該光硬化裝置亦包含用於選擇性激活各LED(LED1至LED4)之激活構件(120)。
