Description

Technical Field

[0001] The utility model relates to the technical field of ultraviolet irradiation, in particular to a device for ultraviolet irradiation experiments. Background Technique

[0002] Ultraviolet irradiation, that is, ultraviolet radiation, is a non-illuminating radiation source with a wavelength range between 10 nanometers and 400 nanometers. Since only ultraviolet radiation with a wavelength greater than 200 nanometers (there is also a saying of 100 nanometers) can propagate in the air, the ultraviolet radiation effects and their applications usually discussed by people mainly involve the radiation within this wavelength range. For the convenience of research and application, scientists divide ultraviolet radiation into different bands and name them UVA, UVB, and UVC respectively. Sterilization effect: The UVC band has a strong destructive effect on microorganisms and can kill a variety of bacteria and viruses, and is widely used in the disinfection field. Erythema effect: The radiation in the UVB band can cause skin erythema, which is one of the manifestations of skin sunburn. Pigmentation effect: The radiation in the UVA band can cause skin pigmentation, that is, the black spot effect. Appropriate pigmentation has a certain protective effect on the human body. Health effect: Appropriate ultraviolet radiation can promote the synthesis of vitamin D in the human body, which is beneficial to the prevention and treatment of rickets and osteoporosis. Photosensitization effect: Some substances will produce decomposition, polymerization, and metamorphosis under ultraviolet irradiation, and this effect is widely used in the industrial field, such as the printing of photocurable inks. Fluorescence effect: After short-wave ultraviolet light irradiates fluorescent substances, the fluorescent substances will emit light in the long wave band, and this effect is applied to lighting equipment such as fluorescent lamps.

[0003] According to a UV irradiator for establishing a UV-irradiated cell detection model with a publication number of CN203350170U announced by the Chinese Patent Network, the device is composed of a lamp source, a main body, and a support rod. The lamp source and the main body are respectively vertically connected to the support rod, and the lamp source and the main body are parallel and opposite to each other up and down. The device can provide a surface light source with uniform irradiation intensity, meeting the needs of large-scale preparation of cell models; it can adjust the distance between the light source and the irradiated object, control the irradiation intensity, is convenient to operate, and can ensure the stability of cell models between batches; it can monitor and display the current irradiation intensity and total irradiation dose in real time, facilitating the collection of experimental data; the main body is equipped with a timer and a buzzer, and the irradiation time can be set according to requirements, automatically turning off the ultraviolet lamp tube, and there is a sound prompt after the irradiation is completed, without manual operation, and it is convenient and fast to use.
