Title:
LIGHT SOURCE DEVICE AND STAGE LAMP ILLUMINATION SYSTEM USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2019/019592
Kind Code:
A1
Abstract:
Provided is a light source device, comprising a first light source module (100), a second light source module (200), a third light source module (300), a first filter (400), and a second filter (500). The first light source module (100) emits a first light having a wavelength in a first spectral range. The second light source module (200) emits complex color light, and the complex color light comprises a second light having a wavelength in a second spectral range and a third light having a wavelength in a third spectral range. The third light source module (300) emits a fourth light in the second spectral range. The first filter (400) transmits the first light and the third light, reflects the second light, and reflects the fourth light to a light exit to be outputted. The second filter (500) transmits the third light and the fourth light and reflects the first light to the light outlet to be outputted. The first light source module (100) is provided with a first isolation device for preventing the second light from entering the first light source module (100). The light source device has stable light source and low light attenuation, and the stage lamp illumination system using the light source device has stable light output, high brightness and good color quality.
