Embodiment 1
[0024] figure 1 shows the concrete structure of the present invention, by figure 1 It can be seen that the LED irradiation photosynthetic ability rapid detector includes darkroom 1, LED light source J7, optical fiber 3, photomultiplier tube module J4, A / D converter U6, single-chip microcomputer U1, input keyboard 5, display 4, serial interface J2, The LED light source J7 is located in the darkroom 1, one end of the optical fiber 3 extends into the darkroom 1, and the other end is connected with the photomultiplier tube module J4, and the photomultiplier tube module J4 is connected with the single-chip microcomputer U1 through the A / D converter U6, input keyboard 5, The display 4 is connected with the single-chip microcomputer U1 at the same time, and the single-chip microcomputer U1 is also connected with a serial interface J2, and can communicate with the computer through the serial interface J2. The structure of the darkroom 1 is as figure 2 shown by figure 2 It can be ...
Embodiment 2
[0027] This embodiment is the same as embodiment 1 except for the following features: the upper and lower chamber bodies of the darkroom are completely split and separated structures, and the internal structure is the same as that of embodiment 1; when not in use, the upper and lower chamber bodies can be Separate, and connect the upper and lower chambers when needed.
Embodiment 3
[0029] This embodiment is the same as Embodiment 1 except for the following features: the darkroom has an integrated structure, a living body insertion hole is provided on the side of the darkroom, and a light-shielding gasket is provided at a position close to the living body insertion hole in the darkroom, which can Compress the living body and block the light to make the dark room light-tight.
