Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reflective cups, in particular to a reflective cup with a replaceable lens. Background Art
[0002] Reflective cups utilize the principle of light reflection to focus light traveling from different directions and are widely used in many fields. In optical detection, reflective cups enable non-contact light collection over a wide angle. Compared to high-NA objective lenses, reflective cup collection solutions are located farther from the light source, facilitating other optical system processing. Surface design can also achieve specific light collection effects, making them widely used for signal light collection. For specific wavelengths, the inner surface of the reflective cup requires a corresponding vapor deposition coating to enhance its optical properties. The optimal orientation of the coating equipment should be with the normal of the coating surface pointing toward the target material for optimal coating results.
[0003] For some parabolic reflectors, the reflective surface converges into a cone-like shape. The closer to the bottom, the smaller the opening. It is difficult to coat the surface evenly during coating. In addition, the lens is fixedly connected to the reflector, so care must be taken during coating. Moreover, as the depth increases, the coating effect varies more. It is common for the bottom of the reflective surface to be uncoated, which seriously affects the use of these parabolic reflectors. Utility Model Content
[0004] The utility model solves the technical problems in the above-mentioned background technology and provides a reflective cup with a replaceable lens.
[0005] In order to solve the above technical problems, the technical solutions provided by the present invention are as follows:
[0006] A reflector with a replaceable lens comprises a reflector body, a slot provided at the lower portion of the reflector body, a PC board slidably connected to the slot, a lens provided at one end of the lens, a block provided at the bottom of the lens, a base fixedly connected to the lower portion of the reflector body, a mounting slot provided on the base, and a bolt slidingly passing through the mounting slot.
[0007] Preferably, the card block is attached to the bottom of the slot, the card block is made of elastic plastic material, and the length of the PC board is greater than the length of the slot.
[0008] Preferably, the base is circular in shape, and an opening is provided on one side of the mounting groove.
[0009] Preferably, the mounting grooves are provided in two groups and are symmetrically arranged.
[0010] Preferably, the size of the opening on one side of the installation slot is smaller than the diameter of the bolt.
[0011] Preferably, the shape of the reflective cup body is bowl-shaped, and arc-shaped protrusions are provided inside the reflective cup body. The arc-shaped protrusions are provided in several groups and are evenly distributed.
[0012] With the above structure, the utility model has the following advantages:
[0013] 1. The removable lens makes it more convenient to coat the entire reflector body, making the coating even. When in use, the lens can be inserted and used, which can also protect the light source from dust. When not needed, the lens can be removed to reduce the cost of replacing the reflector body.
[0014] 2. The refraction effect can be improved by having a pluggable lens. By replacing the lens, the brightness and color of the light source can be controlled without changing the light source. The reflective cup body is provided with arc-shaped protrusions. These protrusions scatter the light inside the reflective cup body, and then refract it multiple times before it shines out. The effect is multiple scattering and refraction, which makes the lighting effect better and the light emitted is softer.
[0015] The above summary is for the purpose of description only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.
[0022] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0023] The following is a further detailed description of the present invention in conjunction with the full text:
[0024] Combined with attachment Figures 1 to 3 The present embodiment provides a reflector with a replaceable lens, comprising a reflector body 1, a slot 2 being provided at the lower portion of the reflector body 1, a lens 3 being slidably connected to the slot 2, a PC board 4 being provided at one end of the lens 3, a clamping block 5 being provided at the bottom of the lens 3, a base 6 being fixedly connected to the lower portion of the reflector body 1, a mounting slot 7 being provided on the base 6, a bolt 8 being slidably passed through the mounting slot 7, the removable lens 3 making it more convenient to coat the entire reflector body 1 so that the coating is evenly distributed, and the lens 3 can be inserted for use during use, thereby protecting the light source from dust, and the lens 3 can be removed when not needed, thereby reducing the cost of replacing the reflector body 1.
[0025] Specifically, the card block 5 is fitted into the bottom of the slot 2. The card block 5 is made of elastic plastic material. The length of the PC board 4 is greater than the length of the slot 2. The base 6 is circular in shape. An opening is provided on one side of the mounting slot 7. The mounting slot 7 is provided in two groups and is symmetrically arranged. The size of the opening on one side of the mounting slot 7 is smaller than the diameter of the bolt 8. The reflector body 1 is bowl-shaped. An arc-shaped protrusion is provided inside the reflector body 1. The arc-shaped protrusions are provided in several groups and are evenly distributed. By providing a pluggable lens, the refraction effect can be improved. By replacing the lens, the brightness and color of the light source can be controlled without changing the light source. The reflector body is provided with arc-shaped protrusions. These protrusions scatter the light inside the reflector body and then refract it multiple times before it is illuminated to the outside. The effect is multiple scattering and refraction, which makes the lighting effect better and the illuminated light is softer.
[0026] The operation steps are as follows: first, insert two sets of bolts 8 through the mounting slots 7 on the base 6, tighten the bolts 8 to fix the device, manually pull the PC board 4 to drive the lens 3 to move outward in the slot 2, at this time the clamping block 5 is squeezed and deformed, and the lens 3 can be removed from the reflector body 1 for replacement and storage. When the lens 3 needs to be inserted, directly pinch the PC board 4 and push the lens 3 into the slot 2 until the clamping block 5 is located inside the reflector body 1, which can provide moving force to prevent the lens 3 from slipping under the action of external force.
[0027] The above description of the present invention and its embodiments is non-limiting. What is shown in the full text is only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
