Abstract

The invention discloses a brightness-adjustable light source device for simulating a specific light source. The light source device comprises a light source module, a light source chamber, frosted glass and an optical fiber group which are coaxially arranged in sequence. The light source module is used for emitting light to cover a visible light near-infrared spectrum waveband and simulating the specific light source, and the brightness and the spectrum are adjustable; the light source chamber is used for carrying out fitting uniform processing on the light emitted by the light source module;the frosted glass is used for further homogenizing the light output by the light source chamber; and the optical fiber group is used for guiding out light output by the frosted glass to form a light source. The light source device can realize effective and high-precision light source simulation; the simulated light source is closer to a real light source, and the effect is good; and the whole device is wide in adjustable range, can simulate specific light sources with different spectrums and different brightness, and is small in structure, easy to integrate and low in power consumption.

Description

technical field [0001] The invention relates to the field of light sources, in particular to a light source device that simulates a specific light source with adjustable brightness. Background technique [0002] With the development of science and technology, people's demand for light source simulation is increasing. The most prominent one is the solar simulator, which simulates the natural sunlight, and its spectrum is stable and the irradiance is uniform, which can be used in related simulation experiments. Nowadays, we focus more on the simulation of some common light sources such as sunlight, but lack the simulation of some common light sources. In some experiments that require these light sources, simulated light sources can be used instead of real light sources for experiments. [0003] The simulation of the light source is generally in the form of LED, and the brightness is adjusted through the current, with few gears and high power consumption; in addition, the integ...
