Abstract
The utility model discloses a multispectral compact type LED (light-emitting diode) all solid-state optical source system, which comprises an LED power supply and a control circuit module. The LED power supply and the control circuit module are connected with a plurality of LEDs with different transmitting wave lengths; the photons of each LED are respectively coupled with a branch optical fiber of a multi-split optical fiber through input end optical fiber tips or optical coupling elements; and the collected LED photons are coupled with a sample by an output overall end optical fiber of the multi-split optical fiber through output end optical fiber tips or optical coupling elements. As multi-split optical fiber luminiferous bundles are adopted, multispectral illumination on the same exit port is realized; and structures like optical filter runners and transmission motors with expensive prices and complex structures are avoided from being used; as the LED power supply is adopted, the energy consumption and the cost are reduced; as the optical fiber luminiferous bundles can be bent, the lengths of the optical fiber luminiferous bundles can be customized according to demands; therefore, the multispectral compact type LED all solid-state optical source system can be flexibly applied to various instrument systems.
