DETAILED DESCRIPTION

[0025] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The main purpose of the present invention is to provide a modular laser module with a detachable internal structure, aiming to realize a modular laser module with a novel and reasonable structure, detachable internal structure, replaceable internal components, convenient inspection and maintenance, reusable components, economic and environmental protection, and effective improvement of product yield.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 7 , an embodiment of a modular laser module with a detachable internal structure of the present invention is proposed, comprising a linear blue laser assembly, a PCB board 101 installed at the lower end of the linear blue laser assembly, a filter lens assembly covered outside the linear blue laser assembly, a fluorescent sheet assembly installed at the upper end of the filter lens assembly, and a lens assembly installed at the upper end of the fluorescent sheet assembly, and also comprising a heat dissipation housing 102 covered outside the linear blue laser assembly, the PCB board 101, the filter lens assembly, the fluorescent sheet assembly, and the lens assembly. The PCB board 101 is a printed circuit board.

[0029] The linear blue laser assembly includes a linear blue laser structure 103, and a laser lens 104 embedded in the linear blue laser structure 103, which can focus the blue laser emitted by the linear blue laser structure 103 from a long strip spot to a circular spot. The cross section of the laser lens 104 is a circular structure, which ensures that the laser is focused from the long spot to the central circular area. Through holes are opened at both ends of the first fixing seat 105, and the inner diameter of the opening below the first fixing seat 105 is larger than the inner diameter of the opening at the top of the first fixing seat 105. The top of the linear blue laser structure 103 is inserted into the opening below the first fixing seat 105.

[0030] The filter lens assembly includes a first fixing seat 105 covered outside the linear blue laser assembly, a diffuser lens 106 embedded in the upper end of the first fixing seat 105, and a filter 107 embedded in the upper end surface of the first fixing seat 105 and located above the first lens. The filter is a frosted sheet. One end of the diffuser lens 106 is a convex arc structure, and the other end is a flat structure. The flat structure of the diffuser lens is located at one end close to the filter 107, and the two can fit tightly. The diffuser lens 106 and the filter 107 can reduce the focusing density of the blue laser and protect the fluorescent film from being broken down to the greatest extent. The upper end of the first fixed seat 105 is provided with a first groove in which the astigmatism lens 106 can be embedded, and a second groove in which the filter 107 can be embedded. The second groove is located above the first groove, and the first groove is located in the first fixed seat 105. The second groove is located at the top edge of the first fixed seat 105. The second groove includes a plurality of flanges evenly distributed on the top edge of the first fixed seat 105. The outer edge of the flange and the outer edge of the first fixed seat 105 are located on the same virtual circle, and the inner edge of the flange is an arc-shaped gradient structure with a diameter that increases evenly from one end to the other.

[0031] The fluorescent sheet assembly includes a second fixing seat 108 which is closely attached to the upper end of the first fixing seat 105, and a fluorescent sheet 109 which is embedded in a concave circular groove on the upper end surface of the second fixing seat 108 and can convert blue laser into white laser. The second fixing seat 108 is a fluorescent sheet fixing seat, and the fluorescent sheet 109 adopts a coated sapphire single-sided fluorescent film, and the fluorescent sheet assembly can convert blue light into white light. The second fixing seat 108 is through-connected at both ends, and the concave circular groove of the second fixing seat 108 is located at the top opening of the second fixing seat 108. The inner diameter of the top opening of the second fixing seat 108 is smaller than the inner diameter of the lower opening of the second fixing seat 108, and the bottom of the second fixing seat 108 is in contact with the top of the flange of the second groove of the first fixing seat 105.

[0032] The lens assembly includes a light cutter 110 closely attached to the upper end of the second fixing seat 108, a focusing lens 111 embedded in the upper end of the light cutter 110, and a third fixing seat 112 covered outside the light cutter 110 and the focusing lens 111. The light cutter 110 is provided with a light cutting hole 113. The white laser irradiates the focusing lens 111 through the light cutting hole 113 and forms a uniform white light spot. A through hole is provided in the middle of the third fixing seat 112, and the outer diameter of one end of the third fixing seat 112 close to the light cutter 110 is smaller than the outer diameter of the other end of the third fixing seat 112. The inner diameter of the through hole at the end with a smaller diameter of the third fixing seat 112 is larger than the inner diameter of the through hole at the end with a larger diameter of the third fixing seat 112, so that the focusing lens 111 and the light cutter 110 can be limitedly set in the through hole at the end with a larger diameter, and at the same time, the central protrusion of the focusing lens 111 can extend out of the through hole at the end with a smaller diameter. A limiting groove is provided at the top of the middle opening of the heat dissipation housing 102, and the end with a smaller outer diameter of the third fixing seat 112 is embedded in the limiting groove at the top of the middle opening of the heat dissipation housing 102, and the two are fixedly connected by threads.

[0033] Each of the above-mentioned components, namely the linear blue light laser component, filter lens component, fluorescent sheet component, and lens component, can be disassembled, making the laser module modular, with a novel and reasonable structure, a detachable internal structure, replaceable internal components, convenient inspection and maintenance, and reusable components. If problems are found in the internal components of the product during inspection after assembly, or if damage is found in the internal components after use, they can be disassembled at any time for inspection and maintenance, and damaged internal components can be replaced in time, which is economical and environmentally friendly, and also effectively improves product yield.

[0034] The PCB board 101 is in close contact with the linear blue laser structure 103, and the PCB board 101 is in close contact with the groove on the outer side of the bottom of the heat dissipation housing 102. The PCB board 101 and the heat dissipation housing 102 can quickly transfer the heat emitted by the linear blue laser structure 103 to ensure the heat dissipation effect of the linear blue laser structure 103. The linear blue laser structure 103 extends two pins 114 downward, and the pins 114 continue to extend outward after passing through the PCB board 101. The heat dissipation housing 102 is made of heat-conducting material. The heat conduction and electrical conduction of the laser tube are guaranteed.

[0035] The invention has a novel and reasonable structure, a detachable internal structure, replaceable internal components, convenient overhaul and maintenance, and reusable components, which is economical and environmentally friendly, and effectively improves product yield.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
