Embodiment Construction

[0055] (1) Build the hardware and software of the light source system

[0056] (1) According to the schematic diagrams in Figure 2 and Figure 3, design the corresponding circuit and make the circuit board. The LED constant current drive circuit shown in Figure 3 is directly designed and manufactured on the array substrate shown in Figure 2, and OUT0-OUT15 in Figure 2 is connected to OUT0-OUT15 in Figure 3. In Figure 2, solder the socket sockets at the locations (D1-D80) corresponding to any of the LEDs. All LEDs will be plugged into these sockets with holes, and can also be easily unplugged from these sockets with holes. This flexible plug-in design ensures that LEDs of any wavelength and quantity can be easily and quickly removed. It can be installed at any position to realize the flexible combination regulation of the wavelength and optical density of the light source system. (2) According to Figure 4, Figure 5, Figure 6, Figure 7 and Figure 8, design the printed circuit b...

The invention solves the problems that the traditional light source cannot provide multi optical spectrum parametric combination, and cannot exactly quantify and modulate the optical spectrum parameters, can perform flexural modulate to the optical spectrum parameters according to the demands of the photobiology research experiment, and can get series light source of the multi optical spectrum parametric combinations with different wavelengths, different light densities, different photoperiods and different operational frequencies through exact quantification.

Description

1. Technical field [0001] The invention relates to a spectrum flexible and adjustable LED (Light-Emitting Diode, light-emitting diode) light source system, which belongs to the field of photobiology technical instruments and is specially used for plant photobiology, animal (human body) photobiology and microbial photobiology And scientific research on the mechanism of biological light signal transduction. 2. Technical Background [0002] Spectral parameters, including wavelength, optical density (Photon Flux Density), photoperiod and operating frequency, play a key role in the growth and development of organisms. Long-term research results have clearly shown that light spectrum affects the growth of organisms and controls the developmental transition of organisms. However, so far, in related scientific experiments, due to the inability to obtain spectrally flexible and adjustable light sources through existing experimental instruments and means, researchers are still unable...
