[0005] At present, most of the light sources used to establish ultraviolet-related biological detection models are traditional mercury lamps, which use mercury vapor to be intensified to emit ultraviolet light. Its advantages lie in low research cost, easy use, and adjustable radiation dose, ensuring batch construction of biological detection. The stability of the model, but this kind of ultraviolet lamp consumes a lot of power and has a short life. The mercury in the lamp is difficult to properly recycle, which will pollute the environment. More importantly, the ultraviolet lamp will generate high heat during the modeling process. and ozone, and high heat and ozone will interfere with biological research

[0006] At present, there are few light sources used to study the biological effects of blue light, which are mainly divided into two categories. One is medical devices with specific uses, such as: 1) Hand-held blue light generation and irradiation equipment, which is based on cells, tissue engineered skin, ion For biological detection models such as human skin, the hand-held light source has the limitation of being unable to control the parallel distance between the light source and the radiation object and the radiation area during use, and the radiation dose cannot be accurately controlled. The repeatability is low and the radiation area is small, so it cannot be used. For the establishment of batch biological detection models; 2) Dental light curing machine, this type of equipment is mainly composed of light curing machine host, optical brazing light guide rod, battery, charging stand, charger, light shield, etc., suitable for internal oral irradiation operation, but because of the slender structure of its optical brazing light guide rod, it cannot meet the needs of large-scale establishment of biological detection models, and cannot display the radiation dose of blue light, which is not convenient for scientific research; 3) Medical units are used for treatment The blue light box of phototherapy equipment for neonatal jaundice, the basic application of which is to reduce the content of unconjugated bilirubin in neonatal serum by blue light irradiation, so as to achieve the effect of treating jaundice. The device has a large radiation area and can achieve the efficiency of batch modeling, but Also due to the large size of the device, it cannot be used in a workbench in a clean area, and it cannot display the irradiation dose of blue light, which is not conducive to modeling; 4) In order to study the biological effects of blue light, the blue light LED assembled by the scientific research laboratory Chip, this assembled equipment is small in size and can be used for ultra-clean bench operation, but this instrument has no dose measurement device, no timing device, and the irradiation area is small, and it is also impossible to achieve large-scale modeling; another type of blue light source is made of It is a device that emits light from ordinary visible light sources and produces blue light after being filtered by a special filter. However, due to the complicated fixing of the position of the light source and the filter, the radiation area is small, and the repeatability is poor, it is not suitable for large-scale modeling.
