Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, and more specifically to a light source component. Background Technology

[0002] Microscope illumination methods can be broadly classified into two categories based on the formation of the illumination beam: "transmitted illumination" and "reflected illumination." The former is suitable for transparent or translucent objects, and the vast majority of biological microscopes use this type of illumination. The latter is suitable for opaque objects, with the light source coming from above; it is also known as "reflected or reflected illumination." It is mainly used in metallurgical microscopy or fluorescence microscopy.

[0003] According to the experimental observation requirements, filters need to be installed on the objective lens or inside the light source assembly. However, the installation of filters in existing microscope light sources is also relatively troublesome. It is necessary to first remove the light source component and then replace the filter on the light source component, which increases the replacement time and also increases the time for the second installation of the light source component. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a light source component to overcome the above-mentioned defects in the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A light source assembly includes a light source element, the center of which has a vision aperture that mates with an objective lens, and a slot on the side wall of the light source element, into which a filter is pluggably connected, such that when the filter is inserted into the slot, the filter covers the vision aperture.

[0007] Furthermore, it also includes a insert with a through-hole for mounting a filter.

[0008] Furthermore, the end of the insert away from the mounting hole is provided with a protrusion.

[0009] Furthermore, it also includes a first connector, which is connected to the objective lens cover of the microscope. Several sets of fixing members are provided between the light source and the first connector, and each set of fixing members is arranged with the central axis of the microscope as the center.

[0010] Furthermore, the surface of the light source component is provided with a connecting wall around the visual hole.

[0011] Furthermore, the fixing member is a magnetic member, the slot is located on the surface of the light source member, and the thickness of the insert is the same as the depth of the slot in the axial direction of the visual aperture.

[0012] Furthermore, the length of the insert is the same as the depth of the slot in the insertion / removal direction, and the inner side of the protrusion has the same curvature as the outer edge of the light source.

[0013] Furthermore, the fixing member is a screw, and the slot is set on the connecting wall. When the light source is connected to the first connecting member, the first connecting member presses against the insert.

[0014] Furthermore, the inner surface of the protrusion has the same curvature as the outer surface of the connecting wall.

[0015] Furthermore, the slot is located between any two sets of fasteners.

[0016] The beneficial effects of this utility model are: by setting a slot on the light source and connecting the filter in the slot in a pluggable manner, the filter can be directly replaced or removed without disassembling the light source, which is convenient and saves time.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0025] According to the experimental observation requirements, filters need to be installed on the objective lens or inside the light source assembly. However, the installation of filters in existing microscope light sources is relatively cumbersome, requiring the removal of light source component 1 before replacing the filter, which increases the replacement time and also adds time for the second installation of the light source component. Therefore, this utility model designs such a light source assembly, such as... Figure 2 and Figure 3 As shown, the microscope includes a light source 1 with a visual aperture 2 at its center that mates with the objective lens. A slot 3 is located on the side wall of the light source 1, into which a filter (including a light filter and an analyzer) is pluggably connected. When the filter is inserted into the slot 3, it covers the visual aperture 2. The microscope also includes a first connector 8, which is threaded onto the objective lens cover. Several sets of fixing members are provided between the light source 1 and the first connector 8. Since three sets of fixing members are used in this invention, with an angle of 120° between each set, the slot 3 is located between any two sets of fixing members. Each set of fixing members is centered on the central axis of the microscope. Therefore, the filter can be directly replaced or removed without disassembling the light source 1, which is convenient and saves time.

[0026] Typically, filters or analyzers are assembled with the round holes in insert 4. Different filters and other functional lenses are used to form fixed components with different functions. For example, if the lens is an analyzer, it is an analyzer; if the lens is a red filter, it is a red filter element; if it is a color temperature correction filter, it is a color temperature correction element.

[0027] like Figure 1As shown, it also includes a insert 4, on which a mounting hole 5 is provided through the insert 4. The diameter of the mounting hole 5 is greater than or equal to the diameter of the visual aperture 2. A mounting base 6 for mounting a filter is provided on the mounting hole 5. A protrusion 7 is provided at the end of the insert 4 away from the mounting hole 5. The protrusion 7 facilitates the insertion and removal of the insert. In addition, a connecting wall 9 is provided around the visual aperture 2 on the surface of the light source 1.

[0028] Example 1:

[0029] like Figure 2 As shown, the fixing component is a magnetic suction component, which includes a magnet 10 and a suction body. There is a gap between the suction bodies in each pair of adjacent magnetic suction components. The magnet 10 can be set on the first connecting member 8 or on the light source component 1. The suction body is set on the light source component 1 or the first connecting member 8 without a magnet. In this utility model, the magnet 10 is set on the light source component 1 and the suction body is set on the first connecting member 8. The magnet 10 includes ordinary magnets and electromagnets, and the suction body is an arc-shaped armature, which is arranged in a ring along the central axis of the microscope.

[0030] When magnet 10 is a common magnet, the attraction force between the magnet and the armature is relatively large. Therefore, when installing the light source component 1, each magnet is aligned with the corresponding armature to ensure that each magnet can be attracted to different armatures. When it is necessary to disassemble and replace the light source component 1, rotate the light source component 1 and rotate the magnet horizontally to the gap between the two armatures. Then each magnet will be rotated to the gap. After the magnet is separated from the armature, it loses the attraction force, which makes it easy to remove the light source component 1.

[0031] When magnet 10 is an electromagnet, the electromagnet in this utility model has the characteristics of being magnetic when not energized and non-magnetic when energized. Its connection method with the armature is the same. Only when it is disconnected from the light source 1 does it need to be energized, without needing to rotate the light source 1.

[0032] To ensure a tight connection between the light source 1 and the first connector 8 and to prevent external dust from entering through the gap between them, the magnet 10 is embedded in the light source 1 so that its surface is flush with the surface of the light source 1. The attractant is embedded in the first connector 8 so that its surface is flush with the surface of the first connector 8. The slot 3 is located on the surface of the light source 1. The thickness of the insert 4 is the same as the depth of the slot 3 in the axial direction of the visual hole 2. When fully inserted into the slot 3, the surface of the insert 4 is also flush with the surface of the light source 1, which will not affect the tight connection between the light source 1 and the first connector 8.

[0033] like Figure 2As shown, the length of the insert 4 is the same as the depth of the slot 3 in the insertion and removal direction. The inner side of the protrusion 7 has the same curvature as the outer edge of the light source 1. When the insert 4 is fully inserted into the slot 3, the light source 1 is connected to the first connector 8 by magnetic attraction. At this time, the protrusion 7 is exposed outside the light source 1, which makes it easy to manually grasp the insert 4 for insertion and removal, and will not affect the tight connection between the light source 1 and the first connector 8.

[0034] Example 2:

[0035] like Figure 3 As shown, the fixing component is a screw component 11, which includes a screw that passes horizontally through the connecting wall 9 and is threadedly connected to the connecting wall 9. The outer side wall of the first connecting component 8 is provided with a groove. When the light source component 1 needs to be fixed on the first connecting component 8, the head of the screw is rotated and pushed into the groove of the first connecting wall 9 by rotating the screw.

[0036] The slot 3 is set on the connecting wall 9. When the light source 1 is connected to the first connecting member 8, the first connecting member 8 presses against the insert 4. The inner side of the protrusion 7 has the same curvature as the outer side of the connecting wall 9. At this time, when the insert 4 is inserted into the slot 3, in order to make it easy to show whether the insertion position is in place, it is judged by whether the inner side of the protrusion 7 is close to the outer side of the connecting wall 9. The protrusion 7 is exposed outside the light source 1, which makes it easy to manually insert and remove the insert 4.

[0037] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
