Problems solved by technology

However, the disadvantage of high-pressure mercury lamps is that their spectral distribution is not as close to natural sunlight as xenon lamps. Therefore, if you want to use high-pressure mercury lamps in digital cinema projection systems, you will face the color requirements that cannot meet the specifications of the Digital Cinema Alliance. The problem

Abstract

The invention relates to a light source system applicable to a digital film projecting device, and the digital film projecting device. The light source system comprises a high-pressure mercury lamp light source emitting a beam, a relay lens group, an optical filtering module, a digital microdisplay module, a lens and a screen, wherein the relay lens group is used for receiving the beam and adjusting a travel path of the beam; the optical filtering module is arranged in the travel path of the beam; the lens receives the calibrated beam and projects an image beam; and the beam is subjected to optical calibration in at least one of spectral band and white balance by the optical filtering module, so that the calibrated image beam complies with a color specification of a digital cinema initiative.

Description

technical field [0001] The invention relates to a light source system, especially a light source system which adopts a high-pressure mercury lamp as a light source and is suitable for a digital movie projection device. Background technique [0002] In today's digital cinema field, the vast majority of digital cinema projectors use digital light processing (Digital Light Processing, DLP) digital projection. Moreover, in the current digital cinema projection system, in order to achieve the brightness required for large-scale screen projection and the color standards regulated by the Digital Cinema Initiative (DCI), xenon lamps are generally used as light sources, because the spectrum of xenon lamps is relatively It is close to daylight, so it is easier to meet the color standards regulated by the Digital Cinema Alliance, and the total light output range of the xenon lamp is very wide, and its output power range can range from 1200W to 7000W, so it is enough to provide large-sc...
