Kind Code:
A1
Abstract:
An illumination system (100, 200, 300), comprising a first light source (1), a second light source (2), a third light source (3), a light combining device (4) and a control device. The first light source (1) comprises a plurality of light-emitting chips (101) and fluorescent powder (102) arranged on the plurality of light-emitting chips (101), fluorescent powder (102) is excited to generate at least two spectrum ranges of light, which has the same color and different spectrum, and such a light is a first color light; the second light source (2) is used to generate a second color light; the third light source (3) is used to generate a third color light; light combining device (4) is used to combine the first color light, the second color light and the third color onto the same light path; the control device is used to control the power supply intensity of the first light source (1), the second light source (2) and the third light source (3). The spectrum range and exiting light intensity of the emergent light of the first light source (1) can be controlled by controlling the power supply intensity of a power supply by the control device, thereby taking both color gamut and brightness into consideration.
