Abstract

The invention discloses a multi-band fluorescent illumination device which comprises a first base, a second base and a plurality of driving portions. The first base is provided with a plurality of LED chips. A lens is arranged above the LED chips. The second base is arranged below the first base. The first base is in floating connection with the second base. The driving portions are distributed on the periphery of the first base and drive the first base from the periphery of the first base to move. According to the multi-band fluorescent illumination device, the chips in the needed working state can be rapidly adjusted to the center position, coaxial collimated light emergence is achieved, the good light beam collimation is obtained, and the utilization efficiency of light energy of different bands is effectively improved.

Description

technical field [0001] The invention relates to a fluorescent lighting device, in particular to a multi-band fluorescent lighting device. Background technique [0002] At present, in the field of fluorescence microscopy excitation, for the needs of light sources of different wavelengths, the common solution is to use broadband light sources, such as xenon lamps and halogen lamps, and to realize light excitation of different wavelengths by equipped with multiple filter boxes of different wavelengths. On the one hand, the energy utilization rate is very low, and only a small part of the light energy of the spectral light source is used each time. On the other hand, multiple filter boxes increase the volume of the system and increase the cost. [0003] In the optical system, in order to achieve high-efficiency fluorescent lighting, it is necessary to achieve coaxial collimated emission of light. For a light source containing multiple chips, if the wavelength band needs to be ad...
