Description

Technical Field

[0001] The utility model relates to the field of lenses for projector laser lamps, in particular to an ultra-high temperature resistant reflective lens for projector laser lamps. Background Art

[0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to computers, VCDs, DVDs, BDs, game consoles, DVs, etc. through different interfaces to play corresponding video signals.

[0003] Existing projectors generally use the principle of laser imaging, using a laser (such as a semiconductor laser) to generate a monochromatic, high-brightness laser beam. The laser beam is then modulated by a modulator (such as a liquid crystal panel or DMD display chip) to control the intensity and color of the light. The modulator changes the intensity and color of the laser beam according to the voltage changes of the input signal, thereby displaying different images. In this process, in order to ensure the high definition and accuracy of the imaging, special lenses are required to adjust the focal length and calibrate the light.

[0004] Existing lenses used in projector laser lights generally use high-temperature resistant lenses. This is because the laser beam focuses and generates heat when passing through the lens, so high-temperature resistant lenses are used to ensure the stable operation of the equipment.

[0005] However, in actual use, light passes through the center of the lens and heat radiates outward from the center. The edge temperature is the lowest. In some scenarios, such as when the temperature difference is too large, the edge of the lens may break. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide an ultra-high-temperature-resistant reflective lens for projector laser lights to solve the technical problem that during the actual use of the lens, light passes through the center of the lens and heat is also radiated outward from the center. The edge temperature is the lowest. In some scenarios, such as when the temperature difference is too large, the edge of the lens may break.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an ultra-high-temperature-resistant reflective lens for a projector laser light, comprising a lens cover, a cover plate provided on the lens cover, a second mounting groove provided on the top of the lens cover, a first mounting groove provided on the bottom of the cover plate, the first mounting groove and the second mounting groove being arranged in coordination, a high-temperature-resistant lens being installed between the first mounting groove and the second mounting groove, a first thermally conductive film being provided in the first mounting groove in coordination with the high-temperature-resistant lens, and a second thermally conductive film being provided in the second mounting groove in coordination with the high-temperature-resistant lens.

[0008] By adopting the above technical solution, the high temperature resistant lens is limitedly installed by cooperating with the first mounting groove through the second mounting groove, and the lens is clamped by cooperating with the second thermal conductive film.

[0009] The present invention is further configured such that a connection groove is provided on a surface of the lens cover close to the cover plate, and a connection ring is provided on the bottom of the cover plate to match the connection groove.

[0010] By adopting the above technical solution, the lens cover and the cover plate are combined together through the provided connecting groove and the connecting ring, thereby completing the assembly of the entire lens structure.

[0011] The present invention is further configured such that a mounting groove is provided at the bottom of the lens cover, and a threaded groove is provided on the inner wall of the mounting groove.

[0012] By adopting the above technical solution, the entire device is mounted on the projector body through the provided threaded groove.

[0013] The present invention is further configured such that a through slot is provided on the cover plate, and the through slot is communicated with the first installation slot.

[0014] By adopting the above technical solution, the air flow inside the lens cover is ensured by the provided through grooves, thereby preventing the temperature of the lens from being too high.

[0015] In summary, the present invention has the following beneficial effects:

[0016] The utility model places the lens therein by providing a first mounting groove and a second mounting groove which are opened on the lens cover and the cover plate, and at the same time flexibly clamps the lens by providing a first thermally conductive film and a second thermally conductive film in the first mounting groove and the second mounting groove, thereby protecting the lens. When the projector is working, the laser passes through the lens and the lens heats up. At this time, the through groove is provided to ensure air circulation in the device, thereby further enhancing the cooling effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] An ultra-high temperature resistant reflective lens for projector laser light, such as Figure 1-6 As shown, it includes a lens cover 1, a cover plate 2 is provided on the lens cover 1, a second mounting groove 11 is provided on the top of the lens cover 1, and a first mounting groove 8 is provided at the bottom of the cover plate 2, the first mounting groove 8 and the second mounting groove 11 are matched, and a high-temperature resistant lens 5 is installed between the first mounting groove 8 and the second mounting groove 11. During actual use, the high-temperature resistant lens 5 is placed in the second mounting groove 11, and then the cover plate 2 is snap-connected with the lens cover 1 to confine the high-temperature resistant lens 5 in the first mounting groove 8 and the second mounting groove 11. A connecting groove 7 is provided on the side of the lens cover 1 close to the cover plate 2, and a connecting ring 6 is provided at the bottom of the cover plate 2 to match the connecting groove 7. During actual use, the lens cover 1 is connected to the cover plate 2 by matching the provided connecting ring 6 with the connecting groove 7.

[0027] Furthermore, a first thermally conductive film 9 is provided in the first mounting groove 8 to cooperate with the high-temperature resistant lens 5, and a second thermally conductive film 12 is provided in the second mounting groove 11 to cooperate with the high-temperature resistant lens 5. When the lens cover 1 and the cover plate 2 are assembled and installed, the first thermally conductive film 9 and the second thermally conductive film 12 provided in the first mounting groove 8 and the second mounting groove 11 clamp the high-temperature resistant lens 5. At the same time, the first thermally conductive film 9 and the second thermally conductive film 12 clamp the edge of the lens, ensuring that the temperature of the lens edge will not be too high when the temperature of the lens rises.

[0028] Among them, the first thermally conductive film 9 and the second thermally conductive film 12 are both set to a wavy film effect, and are set to a hollow structure. The first thermally conductive film 9 and the second thermally conductive film 12 are provided with air outlets. In this way, during the actual installation process, the cover plate 2 is installed on the lens cover 1, so that the first thermally conductive film 9 cooperates with the second thermally conductive film 12 to clamp the high-temperature resistant lens 5. While clamping, the thermally conductive film is squeezed and deformed, and the gas in the cavity is discharged through the air outlet, which maintains a hollow state, thereby having a buffering effect on the high-temperature resistant lens 5.

[0029] Furthermore, a mounting groove 4 is provided at the bottom of the lens cover 1, and a threaded groove 10 is provided on the inner wall of the mounting groove 4. In actual use, the mounting groove 4 is aligned with the projection port on the projector, and then the lens cover 1 is installed on the projector by rotating.

[0030] The cover plate 2 is provided with a through groove 3, which is connected to the first mounting groove 8. During actual use, the projection laser light passes through the high-temperature resistant lens 5, and the temperature of the high-temperature resistant lens 5 rises accordingly. At this time, the through groove 3 ensures the flow of air inside the mounting groove, which has a mobile cooling effect on the lens, thereby increasing the service life of the lens. At the same time, the air flow in the mounting groove is ensured to prevent water vapor from condensing on the lens, resulting in a reduction in imaging effect.

[0031] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
