Light source with spectral distribution and brightness capable of being freely tuned and light source tuning method

Abstract

The invention belongs to the field of optical lighting and particularly relates to a light source with spectral distribution and brightness capable of being freely tuned and a light source tuning method. The light source comprises a compound color line light source, a collimating lens, a tuning system, a homogenization system and a monitoring and controlling system which are sequentially distributed in the optical path direction; the tuning system comprises a light splitting element and a digital micro-mirror element which are sequentially distributed in the optical path direction; the homogenization system is composed of a scatter or a non-imaging optical system; the monitoring and controlling system comprises a spectroradiometer and a control computer connected with the spectroradiometer; and the control computer is connected with the digital micro-mirror element. According to the light source with spectral distribution and brightness capable of being freely tuned, by controlling the opening and closing state of sub-mirrors of the digital micro-mirror element, the spectral distribution and the brightness can be freely adjusted, operation is easy and efficient, and the light source with spectral distribution and brightness capable of being freely tuned has wide application prospects in the fields of space, oceans, environment, industrial vision and the like, and in the aspects of laboratory magnitude simulation, color calibration, camera radiation calibration, spectrograph spectral calibration and the like.

Description

technical field [0001] The invention belongs to the field of optical lighting, and in particular relates to a light source and a light source tuning method whose spectral distribution and brightness can be tuned arbitrarily. Background technique [0002] The light source is an object that emits light. Light is a kind of electromagnetic wave, which is arranged into a spectrum according to the order of electromagnetic wave wavelength. The wavelength range of the spectral region is from about 1mm to 10nm, and it is classified into infrared, visible light and ultraviolet light. Natural light sources often cannot meet people's use requirements, so lighting sources are widely used in daily life, laboratory observation and other fields. The lighting sources used in daily life are often various visible light lamps. With the improvement of people's quality of life, the requirements for lighting sources are getting higher and higher. They are often divided into warm polychromatic ligh...
