Abstract

The invention discloses a reflection-type LED (Light Emitting Diode) light source system in a near-infrared noninvasive blood constituent detector and belongs to the field of optical design. The system comprises at least one LED light source, an annular circuit board, a concave reflecting mirror and a light pass hole, wherein LEDs are mounted on the annular circuit board in an equivalent interval; the annular circuit board, the concave reflecting mirror and the light pass hole are coaxially arranged; and light rays emitted by the LED light source irradiate the concave reflecting mirror, converged by the concave reflecting mirror and then pass through the hollow part of the annular circuit board to form a light spot via the light pass hole. Compared with the structure of the traditional light source system, the light source system has the advantages that the structure is obvious and concise; the number of optical elements is small; the illumination uniformity is improved while the optical energy loss is reduced; the calorific value of a light source is effectively controlled; the detection precision and stability of the near-infrared noninvasive blood constituent detector are improved; and the market of a novel portable noninvasive blood constituent detector is favorably opened.

Description

technical field [0001] The invention belongs to the optical field of a near-infrared non-invasive blood component detector, in particular to a reflective LED light source system in a near-infrared non-invasive blood component detector. Background technique [0002] Blood biochemical test is one of the basic means of health diagnosis. Near-infrared spectroscopy has become one of the most promising hot technologies in the field of non-invasive blood component detection research due to its advantages of non-destructive, rapid and simultaneous multi-component analysis. The light source system is an important part of the near-infrared non-invasive blood component detection instrument. While providing an effective detection spectrum range, the illumination and distribution uniformity of the light source at the test site will affect the accuracy and stability of the test results. Moreover, in order to pursue the portability of non-invasive blood component testing instruments, the ...
