Description

Technical Field

[0001] The utility model relates to the technical field, in particular to an excitation light conversion component of an immunoassay analyzer. Background Art

[0002] Immunofluorescence testing involves linking fluorescein to antibodies to form fluorescent antibodies, which then react with antigens in the specimen to be tested. The reactants are then placed under a fluorescence microscope to observe the fluorescence emitted by the antigen-antibody complex, thereby identifying and locating the antigen in the specimen. Fluorescent antibodies require excitation light to emit the fluorescence used for identification, so the excitation light setting in the immunofluorescence detection system is crucial to the accuracy and quality of the immunofluorescence test. In existing immunofluorescence detection systems, light from a light source is reflected or transmitted through a dichroic mirror to select a specific wavelength, and then illuminates the analyte directly or via optical fiber transmission. Compare with the following existing patents: 1. The application number is "202211374781.1", the application date is "2022.11.04", the publication number is "CN115791720A", the publication date is "2023.03.14", and the name is "A method for setting excitation light in an immunofluorescence detection system". This invention patent discloses a method for setting excitation light in an immunofluorescence detection system: multiple LEDs are used as excitation light sources, and the corresponding light source is selected to emit light according to different fluorescent antibodies. The excitation light is transmitted through optical fibers throughout the entire process, so that the position of the light source can be flexibly arranged, the installation space required for the excitation light equipment is small, and the transmission of the excitation light is not affected by vibration. The excitation light is transmitted to the periphery of the analyte through multiple optical fibers, and the excitation light emitted from multiple output ends illuminates the analyte from different directions, forming the illumination effect of a ring-shaped shadowless lamp. However, this patent uses a method of lighting different LEDs to switch the excitation light source, primarily to address the problem of uneven excitation light irradiation of the photosensitive antibody. The excitation light is transmitted to the aggregator using optical fibers, and then distributed to multiple optical fibers for transmission. This results in significant excitation light loss, requiring a higher-power light source and increasing energy consumption. This patent improves the light source conversion component, enabling efficient conversion between different excitation lights and making the light source easily replaceable and maintainable.
