Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but only represents the selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative efforts belong to the scope of protection of this application.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0034] The aluminum reflection cone rod is a relatively mature optical element, which can be used to couple the light emitted by discrete LED devices with high efficiency, making the generated light more uniform. However, due to the tolerances of the components themselves and the installation errors, the aluminum reflection cone rod in the light source structure may deviate too much from the LED light-emitting plate, resulting in a lower light-emitting efficiency of the LED light-emitting plate.

[0035] Therefore, in the embodiments of this application, a light source structure device is provided to solve or partially solve the above problems.

[0036] Please refer to Figures 1 - 5 and Figure 10 , the light source structure device 100 includes: a light-emitting element 1, a substrate 2, a positioning plate 3, a reflector 4, and a first limiting member 5.

[0037] The substrate 2 includes a first surface 21 and a second surface 22 arranged oppositely. The light-emitting element 1 is fixed on the first surface 21, and the second surface 22 is fixed in the first area of the positioning plate 3.

[0038] The reflector 4 includes a first opening 41 and a second opening 42 arranged oppositely. The diameter of the first opening 41 is smaller than the diameter of the second opening 42.

[0039] The first limiting member 5 has a groove 51 that matches the shape of the reflector 4. The groove 51 has a first notch 511, a second notch 512, and an observation window 513. The first notch 511 corresponds to the first opening 41, the second notch 512 corresponds to the second opening 42, and the observation window 513 is an opening corresponding to the bottom surface of the groove 51. The groove 51 is used to accommodate the reflector 4, and the first limiting member 5 is used to fix the reflector 4 in the groove 51.

[0040] The end face of the first limiting member 5 facing the positioning plate 3 includes a first end face 52. The first end face 52 is fixedly connected to the second region of the positioning plate 3. There is a gap between the first opening 41 of the reflector 4 and the substrate 2, and the first region and the second region are located on the same side of the positioning plate 3.

[0041] The light-emitting element 1 corresponds to the first opening 41, so that the light emitted by the light-emitting element 1 enters the inner cavity 43 of the reflector 4 from the first opening 41 and exits from the second opening 42.

[0042] During installation by the staff, the correspondence between the light-emitting element 1 and the first opening 41 can be viewed through the observation window 513. If the light-emitting element 1 and the first opening 41 are offset too much, adjustment can be made in time so that the light-emitting element 1 is aligned with the first opening 41 after adjustment, ensuring that the luminous efficiency of the installed light source structure meets the requirements.

[0043] It should be noted that, please refer to Figures 1 - 4 As shown, the light-emitting element 1 is fixed on the first surface 21 of the substrate 2 and can be connected to an external power source through a wire 11. When the circuit of the light-emitting element 1 is energized, the light-emitting element 1 can emit light. The light-emitting element 1 can be an LED lamp, an incandescent lamp, a halogen lamp, a fluorescent lamp, or a laser diode, and no specific limitation is made here.

[0044] It can be an independent light-emitting element 1 fixed on the first surface 21 of the substrate 2, or an array of light-emitting elements 1 fixed on the first surface 21 of the substrate 2.

[0045] The diameter of the first opening 41 of the reflector 4 is smaller than the diameter of the second opening 42. The light emitted by the light-emitting element 1 enters the inner cavity 43 of the reflector 4 from the first opening 41 and exits from the second opening 42. The reflector can be conical or trumpet-shaped. The specific shape and specific dimensions of the reflector can be determined according to the actual product requirements.

[0046] Please refer to Figure 4 And Figure 11 As shown, a conical reflector 4 of an embodiment of the present application is shown. The conical reflector 4 has a first opening 41 and a second opening 42 that are oppositely arranged.

[0047] Specifically, the inner wall of the reflector 4 is made of a material that can reflect light, which can be aluminum, chromium, nickel, or platinum.

[0048] Preferably, the material of the inner wall of the conical reflector 4 is aluminum.

[0049] The light-emitting element 1 corresponds to the first opening 41. When the light emitted by the light-emitting element 1 is transmitted from the first opening 41 to the inner cavity 43 of the reflector 4, the light is reflected by the inner wall of the reflector 4, and the reflected light is emitted from the second opening 42.

[0050] Please refer to Figure 3 and Figure 5 , the first limiting member 5 has a groove 51 that matches the shape of the reflector 4. The groove 51 has a first notch 511, a second notch 512, and an observation window 513. The first notch 511 corresponds to the first opening 41, the second notch 512 corresponds to the second opening 42, the observation window 513 is an opening corresponding to the bottom surface of the groove 51. The groove 51 is used to accommodate the reflector 4, and the first limiting member 5 is used to fix the reflector 4 in the groove 51. When the staff installs the reflector 4 into the groove 51, the orientation of the reflector 4 and the groove 51 can be determined first, so that when the reflector 4 is in the groove 51, the shape of the reflector 4 matches the shape of the groove 51. Please refer to Figure 5 As shown in

[0051] Preferably, the reflector 4 abuts against the bottom surface of the groove 51, and the gap between the reflector 4 and the side surface of the groove 51 is 0.1 mm.

[0052] It should be noted that, please refer to Figures 3 - 4 and Figure 10 , the end surface of the first limiting member 5 facing the positioning plate 3 includes a first end surface 52, and the first end surface 52 is fixedly connected to the second area of the positioning plate 3. There is a gap between the first opening 41 of the reflector 4 and the substrate 2. The first area and the second area are on the same side of the positioning plate 3; that is, the reflector is fixed in the groove 51 of the first limiting member 5, the substrate 2 is fixed in the first area of the positioning plate 3, and by fixing the first limiting member 5 in the second area of the positioning plate 3, the purpose of making the light-emitting element 1 correspond to the first opening 41 can be achieved, and the reflector 4 can couple the light emitted by the light-emitting element 1.

[0053] It should be noted that for products of different models, the shape and size of the positioning plate may be different, and the size of the first area and the relative position of the first area with respect to the positioning plate may also be different.

[0054] Due to the tolerances of the components themselves and installation errors by staff, the reflector and the light-emitting element in the light source structure may be offset too much. When the reflector and the light-emitting element are offset too much and the first opening is not aligned with the light-emitting element, the product after the light source structure is packaged will also be difficult to meet the standards.

[0055] Existing light source structure, such as Figure 12 As shown, after the substrate 2 provided with the light-emitting element is installed on the positioning plate 3, when the reflective assembly 9 is installed on the positioning plate 3, the reflective assembly 9 is completely fitted with the positioning plate 3. After the staff fixes the reflective assembly 9 with the positioning plate 3, they cannot see the alignment of the light-emitting element and the reflector at all. Therefore, when the light-emitting element and the reflector are not aligned, they cannot be adjusted in time, which easily leads to a low pass rate of the installed light source structure device, reducing the production efficiency of the product. If the alignment of the light-emitting element and the first opening can be observed in time, the production of unqualified light source structure devices can be avoided, thereby improving production efficiency.

[0056] The present application fixes the reflector into the groove, and there is a gap between the reflector and the substrate, that is, the light source structure device of the present application. When the staff fixes the first stopper and the positioning plate, they can observe the alignment of the light-emitting element and the first opening of the reflector from the observation window of the groove. Alignment can be understood as the luminous flux of the light emitted by the light-emitting element entering the first opening meets the preset requirements. When the staff sees that the light-emitting element and the reflector are offset by a large amount, at this time, the luminous flux of the light emitted by the light-emitting element entering the first opening does not meet the preset requirements.

[0057] The reasons for the misalignment of the light-emitting element with the first opening include installation errors by the staff and unqualified components. If the light-emitting element is not aligned with the first opening, the staff can replace the component or check whether the installation steps and installation matters are correct, and provide timely feedback or adjustments to align the light-emitting element with the first opening after adjustment, ensuring that the luminous efficiency of the installed light source structure meets the requirements, thereby improving the qualified rate of the light source structure device.

[0058] It should be noted that the first limiting member is used to fix the reflector in the groove. The reflector can be fixed in the groove by the first limiting member. For example, at least one snap-in structure is provided at the opening of the groove of the first limiting member. When the reflector is installed in the groove, the snap-in structure is compressed and deformed by force and is in an unlocked state. After the reflector is installed in the groove, the deformation of the snap-in structure is reduced and is in a locked state, and it abuts against the reflector, thereby fixing the reflector in the groove.

[0059] For further information, see Figures 1 - 5As shown in the figure, the light source structure device further includes: a second limiting member 6, which is arranged at the observation window 513 of the groove 51 and fixedly connected to the first limiting member 5 for fixing the reflector 4 in the groove 51. There is a gap between the second limiting member 6 and the substrate 2, and the gap between the second limiting member 6 and the substrate 2 is greater than the gap between the first opening 41 of the reflector 4 and the substrate 2.

[0060] The second limiting member 6 is of a plate-like structure and has a through-hole. The first limiting member 5 is provided with a corresponding threaded hole, and the first limiting member 5 and the second limiting member 6 are fixedly connected by screws. The gap between the second limiting member 6 and the substrate 2 is greater than the gap between the first opening 41 of the reflector 4 and the substrate 2. The staff can directly observe the alignment of the light-emitting element 1 and the reflector 4 through the observation window 513 and can make timely adjustments.

[0061] Preferably, the second limiting member has a first protrusion at one end away from the positioning plate and facing the opening of the groove. The first limiting member is provided with a first groove corresponding to the first protrusion. The first protrusion and the first groove are used in cooperation. When the second limiting member is installed on the first limiting member, precise positioning is carried out through the first protrusion and the first groove. When the first protrusion is embedded in the first groove, it means that the first positioning member and the second positioning member reach the preset position, and they can be fixed by screws.

[0062] Furthermore, the end face of the first limiting member facing the positioning plate further includes a second end face, which corresponds to the substrate and has a gap with the substrate.

[0063] When the second end face corresponds to the substrate 2 and has a gap with the substrate 2, the pore corresponding to the position of the substrate 2 is larger, and the alignment of the light-emitting element 1 and the first opening 41 of the reflector 4 can be viewed more quickly.

[0064] Furthermore, please refer to Figure 1 With Figure 10 , at least two through-holes 53 are provided at the position of the first end face 52 on the first limiting member 5. Threaded holes 31 corresponding to the through-holes 53 are provided in the second area of the positioning plate 3 facing the first limiting member 5. Screws respectively pass through each through-hole 53 and are fixedly connected to the corresponding threaded holes 31. To realize the fixed connection between the first limiting member 5 and the positioning plate 3.

[0065] Regarding the installation method of the existing light source structure, please refer to Figure 12, first fix the substrate 2 on the positioning plate 3. The worker screws to fix the substrate 2 along the direction of H3. Then when installing the reflection component 9 on the positioning plate 3, screw to fix the reflection component 9 along the direction of H4. That is, when the worker installs the substrate 2 and the reflection component 9, the orientation of the positioning plate 3 needs to be changed midway. During the production process of the assembly line, changing the orientation of the positioning plate 3 greatly increases the processing time, thereby increasing the production cost of the product.

[0066] In this application, please refer to Figures 9 - 10 , when the worker installs the substrate 2 and the first limiting member 5, only need to install the substrate 2 along the direction of H2 and install the first limiting member 5 along the direction of H2, without changing the orientation of the positioning plate 3, thereby saving the installation time.

[0067] In addition, the first end face 52 of this application abuts against the positioning plate 3, and the surface-to-surface contact can ensure the flatness of the installation.

[0068] Further, a positioning post 54 is provided on the end face of the first limiting member 5 facing the positioning plate 3, and a positioning hole 32 corresponding to the positioning post 54 is provided at a non-first region of the positioning plate 3;

[0069] The shape of the positioning hole 32 matches the cross-sectional shape of the positioning post 54, and the positioning hole 32 is used to limit the movement of the positioning post 54 on the plane where the positioning plate 3 is located.

[0070] Please refer to Figure 10 , a positioning post 54 is provided on the end face of the first limiting member 5 facing the positioning plate 3, and a positioning hole 32 matching the positioning post 54 is provided on the positioning plate 3. The positioning hole 32 is used to limit the movement of the positioning post 54 on the plane where the positioning plate 3 is located. When fixing the first limiting member 5 and the positioning plate 3, the positioning post 54 of the first limiting member 5 can be inserted into the corresponding positioning hole 32 of the positioning plate 3 to limit the movement of the first limiting member 5 on the plane where the positioning plate 3 is located. Then press the first limiting member 5 along the direction of H2 until the first end face 52 abuts against the positioning plate 3, and lock the first limiting member 5 and the positioning plate 3 by screwing a screw through the through hole 53 and the corresponding threaded hole 31. In this application, the first limiting member 5 and the positioning plate 3 can be quickly positioned through the positioning post 54 and the positioning hole 32, and then the first limiting member 5 can be quickly fixed on the positioning plate 3, improving the processing efficiency of the light source structure device.

[0071] Further, please refer to Figure 9 , the first region of the positioning plate 3 has a positioning groove 33, the shape of the positioning groove 33 matches the shape of the substrate 2, and the substrate 2 is fixed in the positioning groove 33.

[0072] It should be noted that the first area of the positioning plate is preset. The first area is used to install the substrate, so that the light-emitting elements on the substrate are aligned with the first opening of the reflector.

[0073] An exemplary process for installing the substrate 2 into the first area of the positioning plate 3 can be as follows: after applying thermal grease on the surface of the second side 22 of the substrate 2, place it into the positioning groove 33. It is also possible to open at least two through holes on the substrate 2, and set threaded holes corresponding to each through hole on the positioning plate 3. By screwing the screws through each through hole and tightening them with the corresponding threaded holes, the precise positioning of the substrate 2 and the positioning plate 3 can be achieved.

[0074] Preferably, the depth of the positioning groove 33 is 0.5 mm, and 4 screws are used to fix the substrate 2 and the positioning plate 3.

[0075] Preferably, the positioning plate 3 is a heat dissipation plate. Since the light-emitting element 1 is fixed on the substrate 2, and the substrate 2 is fixed on the heat dissipation plate, the heat generated by the light-emitting element 1 can be dissipated through the heat dissipation plate. The specific material of the heat dissipation plate is not specifically limited.

[0076] Further, please refer to Figure 4 With Figure 6 , on the side of the first limiting member 5 facing away from the positioning plate 3, there is a first square groove 55. A Fresnel lens 7 is clamped in the first square groove 55. The surface of the Fresnel lens 7 facing the light-emitting element 1 abuts against the second opening 42 of the reflector 4.

[0077] It should be noted that the width of the first square groove 55 matches the thickness of the Fresnel lens 7, so that the Fresnel lens 7 is clamped in the first square groove 55. The reflector 4 can be restricted from moving in the width direction and the depth direction of the groove 51 by the first limiting member 5 and the second limiting member 6, and the reflector 4 can be restricted from moving in the length direction of the groove 51 by the Fresnel lens 7. Thus, the reflector 4 can be fixed in the groove 51.

[0078] Compared with conventional convex lenses and concave lenses, the Fresnel lens of the present application can reduce the thickness and weight of the lens.

[0079] Further, please refer to Figure 4 With Figure 7 , on the side of the first limiting member 5 facing away from the positioning plate 3, there is a second square groove 56. A brightness enhancement sheet 8 is clamped in the second square groove 56. The Fresnel lens 7 is located between the reflector 4 and the brightness enhancement sheet 8.

[0080] It should be noted that the width of the second square groove 56 matches the thickness of the brightness enhancement sheet 8, so that the brightness enhancement sheet 8 is clamped in the second square groove 56. By designing the brightness enhancement sheet 8 in the present application, the brightness and contrast of the light source structure device can be effectively improved.

[0081] As an embodiment, the installation process of the light source structure device proposed in this application is as follows. Please refer to Figure 5 , install the reflector 4 along the H1 direction into the groove 51 of the first limiting member 5. Among them, the first opening 41 corresponds to the end with a smaller opening of the groove 51, and the second opening 42 corresponds to the end with a larger opening of the groove 51. Then please refer to Figure 6 , install the Fresnel lens 7 along the H1 direction into the first square groove 55, so that the Fresnel lens 7 is clamped in the first square groove 55, and the surface of the Fresnel lens 7 facing the light-emitting element 1 abuts against the second opening 42 of the reflector 4. Please continue to refer to Figure 7 , install the brightness enhancement film 8 along the H1 direction into the second square groove 56, so that the brightness enhancement film 8 is clamped in the second square groove 56. After installing the reflector 4, the Fresnel lens 7 and the brightness enhancement film 8, then install the first limiting member 5. Please refer to Figure 8 , install the first limiting member 5 along the H1 direction, and fixedly connect it to the second limiting member 6 through screws to fix the reflector 4 in the groove. Please refer to Figure 9 , install and fix the substrate 2 along the H2 direction on the first area of the positioning plate 3. After fixing the substrate 2, please refer to Figure 10 , install and fix the first limiting member 5 along the H2 direction on the positioning plate 3. At this time, the positioning post of the first limiting member 5 can be passed through the positioning hole 32 first, and observe whether the light-emitting element 1 is aligned with the first opening of the reflector. If it is aligned, then fix the first limiting member 5 to the positioning plate 3 through screws.
