Electric control multicolor LED fluorescent lighting device

Technical Field

The disclosure relates to the technical field of fluorescent lighting equipment, in particular to an electric control multicolor LED fluorescent lighting device.

Background

When light is irradiated to a certain substance, a phenomenon in which the substance excites light having a longer wavelength than the wavelength of the irradiated light is called a fluorescence phenomenon, in which the irradiated light is called excitation light and the excitation light is called fluorescence. The fluorescence microscope is a microscope that observes by irradiating an object to be observed with light of a certain wavelength as a light source and exciting fluorescence by using such a principle. The inverted fluorescence microscope is one of fluorescence microscopes, and is suitable for microscopic observation and research of tissue culture, cell isolated culture, plankton, environmental protection, food detection, fluid sediments and the like in the fields of biology, medicine and the like.

Currently, high-pressure mercury lamps, xenon lamps or metal halide lamps are commonly used as light sources for fluorescence microscopes, wherein mercury lamps are the most commonly used light sources for fluorescence inverted microscopes. The mercury lamp emits a large amount of heat when in use, so that a good heat dissipation condition is required, and the inverted lamp box is heavy; in order to prolong the service life of the mercury lamp, the mercury lamp cannot be immediately closed after being opened so as to avoid the damage to the electrode caused by incomplete mercury evaporation, and the mercury lamp can be closed after 15 minutes in general; after the mercury lamp is extinguished, the mercury lamp can be restarted after waiting for 30 minutes and being completely cooled, otherwise, the mercury lamp can explode; the mercury lamp emits light with high ultraviolet content, which has harm to human eyes, so an ultraviolet protective cover must be installed. Meanwhile, the conventional mercury lamp bulb has a stable working life of only 200-400 hours and is expensive. The novel cold light source LED has the advantages of long service life, small heat, instant use, continuously adjustable brightness and the like, makes up for the defects of mercury lamp light sources, and is more and more widely applied in the field of microscopes.

An important accessory of fluorescence microscopes is the fluorescence module. The fluorescent module can adjust the wave bands (blue light wave band, red light wave band, green light wave band and the like) of the light emitted by the fluorescent module according to requirements. The current ordinary fluorescence module, personnel will change the fluorescence passageway of observing usefulness in the use, can switch through artifical and electronic mode, and current switching can appear switching inaccurately, and extravagant a large amount of manpowers, causes the inefficiency of work, influences the progress of project.
