Problems solved by technology

In this scheme, each LED light cube needs 1 condenser. If each fluorescence microscope needs to be equipped with 10 band LED light cubes, then 10 condensers are needed, which greatly increases the cost; in addition, in this scheme, LED The module can only be used for a certain microscope due to the fixed focusing system, and the versatility is not high

Embodiment Construction

[0037] The present invention will be further elaborated below with reference to the accompanying drawings and specific embodiments.

[0038] Such as figure 1 and diagram 2-1 , Figure 2-2 As shown, an LED fluorescent lighting device disclosed in the present invention is composed of a plurality of replaceable LED modules 2 installed on a fluorescent excitation switching device and a fixed common condenser lens 3 .

[0039] In the figure, the fluorescence excitation switching device adopts the form of a sliding seat 1, which is installed on the microscope. The sliding seat 1 is equipped with 4 LED modules 2, and the sliding seat 1 can drive the 4 LED modules 2 in the working position and the non-working position in time-sharing. Switch between them, where the working position is to enter the working area of ​​the common condenser 3, and the non-working position is to leave the working area of ​​the common condenser 3.

[0040] Cooperate image 3 and Figure 4 As shown, the...

Abstract

The invention discloses an LED fluorescent lighting device, which consists of a plurality of exchangeable LED modules arranged on a fluorescent stimulation switching device and a fixed common condenser; the LED module is switched between the work area and non-work area by the fluorescent stimulation switching device; the LED module consists of an LED and a color filtering block; while the LED module is positioned on the work station, LED is turned on in the work area of the common condenser, which shines the light to enter into the color filtering block after being converged on the condenser, then to be reflected by light splitting separation film in the color filtering block, finally to be illuminated on the section to stimulate the section to shine the fluorescent light, so that the LED modules with other wavelengths are delivered into the work area of the common condenser in order to realize the switch of the different stimulation wavelengths. The LED fluorescent lighting device realizes time division work of a plurality of LED modules, and reduces the cost of the system while guaranteeing the flexibility of the system.

Description

technical field [0001] The invention relates to the technical field of fluorescent lighting devices in fluorescent microscopes, in particular to a fluorescent lighting device using a plurality of LEDs as light sources. Background technique [0002] Fluorescence microscopy is widely used because of its ability to obtain higher contrast images. In the prior art, a fluorescence microscope is mainly composed of a fluorescence excitation source, a light concentrating system, a color filter block (composed of an excitation filter, a spectroscopic color separation filter, and a blocking filter) and a microscope. The specific principle is: the fluorescence excitation source is energized The emitted light is imaged in the microscope through the concentrating system, the excitation filter (which can only transmit light less than a certain wavelength) and the spectroscopic color separation film (which reflects light less than a certain wavelength and can transmit light greater than thi...
