Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photoelectric colorimetry, in particular to a photoelectric colorimetry module with a stable and controllable single wavelength. Background Art
[0002] Photoelectric colorimetry is a method that uses a photoelectric detector to measure the intensity of light absorbed by a sample solution. It determines the content of a substance in a sample by comparing the absorption of the same light source by the sample and the reagent.
[0003] At present, in the field of solution detection, the traditional device for colorimetric measurement is a halogen lamp + spectroscopic system + photoelectric sensor amplifier and AD conversion circuit, which is then processed by the processor to present the result. The mixed light emitted by the halogen lamp is converted into the required monochromatic light of a specific wavelength by the spectroscopic system, and then irradiates the solution to be tested (the solution is contained in a transparent glass test tube). After that, the photosensitive component converts the light into a voltage signal, which is then converted into a digital signal by the AD conversion circuit and then processed by the processor to present the result. Since the tungsten halogen lamp has high energy consumption, heat dissipation treatment is required, and the light source first passes through the reaction cup and then through the filter and reflector to emit, the light source of multiple channels is obtained, and it is difficult to control the single-wavelength light source of each channel separately. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a stable and controllable single-wavelength photoelectric colorimetric module, which is convenient for realizing the individual control of the single-wavelength light source of each channel.
[0005] The technical solution of the utility model is: a stable and controllable single-wavelength photoelectric colorimetric module, including a colorimetric light source module, a semi-transparent reflective sheet, a reaction cup and a photoelectric conversion receiving end, the colorimetric light source module includes a colorimetric light source box, a channel module arranged in the colorimetric light source box and a plurality of LED light sources symmetrically arranged on both sides of the channel module, a plurality of the semi-transparent reflective sheets are linearly arranged in the channel module, an angle is provided between two adjacent groups of the semi-transparent reflective sheets, the LED light sources are arranged in a one-to-one correspondence with the semi-transparent reflective sheets, the LED light sources obtain light of a specific wavelength through the semi-transparent reflective sheet and transmit it to the reaction cup, and the light is ejected through the liquid in the reaction cup to the photoelectric conversion receiving end for photoelectric conversion.
[0006] It can be seen from the above scheme that the semi-transparent reflector is used to obtain light of a specific wavelength from the LED light source, and several of the LED light sources are used to emit specific monochromatic light in several channels respectively. The LED light source first enters a specific semi-transparent reflector, and then obtains light of a specific wavelength, and then transmits the light of a specific wavelength to the reaction cup, and then emits the light through the liquid in the reaction cup to the photoelectric conversion receiving end to realize photoelectric colorimetry of the reagent in the reaction cup. Because each channel is equipped with an LED light source, the light source of each channel can be controlled separately to obtain a light source of a specific wavelength. The LED light source is a diode light source with low energy consumption and no need for heat dissipation treatment. At the same time, the LED light is a specific monochromatic light and no filter is required. This not only simplifies the process but also saves costs.
[0007] The colorimetric light source box is symmetrically provided with a first light board and a second light board on both sides of the channel module, and the LED light source includes a plurality of first LED lights arranged in parallel on the first light board and a plurality of second LED lights arranged in parallel on the second light board, and the first LED lights and the second LED lights are staggered in correspondence with the semi-transparent reflective sheet. It can be seen that the first light board and the second light board are used to place the LED light source, and the first LED lights and the second LED lights are arranged in a one-to-one correspondence with the semi-transparent reflective sheet, and the first LED lights and the second LED lights are staggered, which is convenient for reducing the volume of the channel module and saving space.
[0008] A plurality of first through slots are equidistantly arranged on one side of the channel module, and a plurality of second through slots are arranged on the other side, wherein the first through slots are arranged corresponding to the first LED lamps, and the second through slots are arranged corresponding to the second LED lamps. It can be seen that the first through slots and the second through slots are respectively used for the first LED lamps and the second LED lamps to penetrate to the corresponding semi-transparent reflective sheets.
[0009] The colorimetric light source box comprises an upper shell and a lower shell connected to the upper shell, and a notch is provided on the side of the colorimetric light source box. It can be seen that the notch is used for light of a specific wavelength to be reflected by the semi-transparent reflective sheet and then emitted from the colorimetric light source box to the reaction cup, and the upper shell and the lower shell are detachably connected to facilitate the disassembly, assembly and replacement of the colorimetric light source box.
[0010] The first lamp board and the second lamp board are provided with a first limiting hole and a second limiting hole respectively, and two groups of limiting members are provided between the first lamp board and the second lamp board in the colorimetric light source box, and the limiting members are provided corresponding to the first limiting hole and the second limiting hole respectively.
[0011] The angle between any two adjacent groups of the semi-transparent reflective sheets is set at a right angle. It can be seen that a plurality of LED light sources are respectively emitted from both sides of the channel module to the corresponding semi-transparent reflective sheets and then reflected and can be transmitted into the reaction cup through the same light path.
