Description

Technical Field

[0001] This utility model relates to the field of LED lamp holder technology, specifically to an adjustable LED lamp holder for an upright fluorescence microscope. Background Technology

[0002] Optical microscopes, as important tools for exploring microscopic particles, are widely used in biology, medicine, materials science, and many other fields. In recent years, with the active promotion of this field by various research institutes, universities, and companies, domestically developed equipment has gradually become mainstream. The design of LED lighting systems is also a crucial aspect of this process. Currently, conventional commercial low-end microscopes and self-assembled equipment typically use a frosted glass lens with a condenser lens, and then align the light path using mechanical dimensions via threads.

[0003] Commercial low-end microscopes and self-built equipment lighting LED installations usually rely mainly on machining. If there are discrepancies between the actual and theoretical measurements or if there are dimensions that are difficult to predict, redesign and reprocessing are required, which increases the time, manpower and economic costs.

Detailed Implementation

[0022] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0025] like Figures 1-7 As shown, an adjustable LED lamp holder for an upright fluorescence microscope includes an adjustment plate 1 and a fixed plate 2 fixed on the adjustment plate 1. The fixed plate 2 is located on both sides of the adjustment plate 1. A mounting base 3 is slidably connected between the fixed plates 2. A support rod 4 is slidably connected in the mounting base 3. An LED light 5 is fixedly connected to one end of the support rod 4, and a microscope frame 6 is fixedly connected to the other end of the support rod 4. The mounting base 3 includes a movable plate 31 and a connecting plate 32. The movable plate 31 is disposed on the fixed plate 2. Two movable plates 31 are provided and are respectively fixed to both ends of the connecting plate 32. A mounting cavity 33 is provided between the movable plates 31. A groove 34 is provided on the movable plate 31, and the support rod 4 is slidably fitted in the groove 34.

[0026] By adopting the above technical solution, the adjustable mounting base 3 and adjusting plate 1 are provided, thereby adjusting the LED lamp 5 to improve the applicability and adjustability of LED lamp illumination, so as to meet the illumination needs of LED lamp 5 in the microscope research and development stage or in various situations with uncertain parameters. The mounting cavity 33 is used to avoid the LED lamp 5 for easy installation.

[0027] Specifically, a first guide bar 35 and a second guide bar 36 are fixedly connected to the movable plate 31. Two first guide bars 35 are vertically arranged on each movable plate 31, with a trapezoidal guide groove between them. A second guide bar 36 is also positioned between the two first guide bars 35, with its surface conforming to the inner wall of the trapezoidal guide groove. A first mounting hole 21 is provided on the fixed plate 2, through which a locking bolt (not shown in the figure) is inserted. The end of the locking bolt passes through the fixed plate 2 and is threadedly connected to the second guide bar 36. Tightening the locking bolt locks the second guide bar 36 between the first guide bars 35. By rotating the locking bolt, the first guide bar 35 can slide up and down, allowing the mounting base 3 to be adjusted to a suitable height. Tightening the locking bolt ensures the second guide bar 36 is flush against the first guide bar 35, preventing it from sliding up and down and achieving a fixed position, thus realizing Z-axis position adjustment.

[0028] Specifically, the adjusting plate 1 has multiple parallel elongated holes 11 for mounting the adjusting plate 1, and the length direction of the elongated holes 11 is perpendicular to the support rod 4. The plate is fixed with bolts through the elongated holes 11, enabling overall movement in the X direction and facilitating adjustment of the overall X-axis position.

[0029] Specifically, the support rod 4 is made of round steel with a diameter of 6mm.

[0030] Specifically, the frame 6 houses a reflector 61, a first lens 62, and a color filter 63. The reflector 61 is mounted at an angle on the frame 6 and is positioned opposite the LED lamp 5. The color filter 63 is located above the reflector 61, and the first lens 62 is located on the side of the color filter 63 away from the reflector 61. A second lens 7 is installed in the end sleeve of the LED lamp 5. The light emitted from the LED lamp 5 passes through the second lens 7 and illuminates the reflector 61. After being reflected by the reflector 61, the light passes through the color filter 63 and is converged by the first lens 62. By setting the first lens 62 and the second lens 7, the illumination light from the LED lamp 5 can be focused to improve the power density of the illumination. The corresponding color filter 63 can be used to excite fluorescent samples.

[0031] Specifically, the frame 6 is provided with a pull-out lens holder 64, and the lens holder 64 is provided with a lens mounting slot for mounting a color filter 63. By providing a lens mounting slot, and having two mounting slots, one in the working position and one empty on one side, it is convenient to install different color filters 63. The color filter can be easily switched by pulling it out, and by switching the color filter, it can be adapted to the excitation of fluorescent samples with different needs.

[0032] The parts not covered in this technical solution can be implemented using existing technologies.

[0033] The foregoing has shown and described the basic principles, main features, and characteristics of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
