Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wavelength conversion, and more specifically, the utility model relates to a fluorescent color wheel with an alignment structure. Background Art
[0002] A laser light source is an electric light source that uses excited particles to emit light under the action of stimulated radiation. Due to its characteristics of high brightness, long propagation distance, and straight propagation path, it is being increasingly widely used in the projection field. In a laser display system, the alignment accuracy of the wavelength conversion layer and the color filter layer has an important impact on the final display effect. The wavelength conversion layer is responsible for converting the laser emitted by the laser into light of different colors, and the color filter layer is responsible for filtering the converted light to achieve the required color output.
[0003] In the prior art, especially in the integrated structure of the fluorescent wheel and the color wheel, alignment is required when assembling the fluorescent wheel and the color wheel. If the fluorescent wheel and the color wheel cannot be aligned, it will directly lead to poor color mixing or unnecessary color deviation, thus affecting the color accuracy and brightness of the image. However, in the current assembly alignment, it is basically aligned by manual experience, aligning the gap connection of the fluorescent wheel with the gap connection of the color wheel. First, the accuracy of this alignment itself is not high. In addition, there is another problem, that is, there is no anti-fooling mechanism, which will lead to directly aligning to another gap connection, directly resulting in the scrapping of the product and causing waste.
[0004] In summary, it is urgent to provide a new design or new structure of the fluorescent color wheel to solve the technical problems existing in the prior art. Summary of the Utility Model

[0034] A fluorescent color wheel with an alignment structure, where the fluorescent wheel and the color wheel are mainly an integral structure, or the fluorescent wheel and the color wheel rotate coaxially; characterized in that the fluorescent color wheel includes:
[0035] A driving mechanism; the driving mechanism can drive the inner ring and the outer ring to rotate at a certain rate, wherein the inner ring and the outer ring rotate synchronously, and the driving structure is generally a motor;
[0036] An inner ring, the inner ring having an inner edge and an outer edge, the inner edge of the inner ring being connected to the driving mechanism; the inner ring includes a first surface and a second surface, and at least two inner ring regions are provided on the first surface of the inner ring; the inner ring can be spliced by transparent glass or can also be spliced by other materials, such as a metal substrate (aluminum substrate); of course, the inner ring can also be a complete structure and is not spliced, such as a complete glass substrate or a complete metal substrate; the inner ring is provided with several partitions according to actual conditions, and each partition can be provided with a diffusion layer, a filter layer, a fluorescent layer or a reflection layer, etc. according to requirements. When a filter layer is provided on the inner ring, generally a fluorescent layer will not be provided on the inner ring, and at this time the inner ring is the color wheel;
[0037] Outer ring, the outer ring has an inner edge and an outer edge, and the inner edge of the outer ring is fixedly connected to the outer edge of the inner ring; the outer ring includes a first surface and a second surface, and at least two outer ring regions are separately provided on the first surface of the outer ring; the outer ring is generally a metal ring, and the regions on the outer ring are also set according to actual situations. Each outer ring region can be provided with a diffusion layer, a light filtering layer, a fluorescent layer or a reflection layer, etc. For example, when a fluorescent layer is provided on the outer ring, generally a fluorescent layer will not be provided on the outer ring;
[0038] Alignment structure, the alignment structure is located at the inner edge of the outer ring, and a junction formed between two adjacent inner ring regions on the first surface of the inner ring is aligned with the alignment structure; or, the alignment structure is located at the outer edge of the inner ring, and a junction formed between two adjacent inner ring regions on the first surface of the outer ring is aligned with the alignment structure; generally when designing specific functional layers in different regions of the inner ring and the outer ring, the alignment structure on the outer ring will be designed to be aligned with a preset position on the inner ring, or the alignment structure on the inner ring will be designed to be aligned with a preset position on the outer ring.
[0039] In one embodiment, the alignment structure is a registration groove opened at a preset position on the inner edge of the outer ring, or a registration groove opened at a preset position on the outer edge of the inner ring; in this way, during the assembly process of the inner ring and the outer ring, as long as the registration groove is aligned with the preset junction; there is also a foolproof structure, the foolproof structure is located at the inner edge of the outer ring; or, the foolproof structure is located at the outer edge of the inner ring.

In this way, it is equivalent to arranging the first surface of the inner ring at the step at the edge of the outer ring, and the inner ring and the outer ring are fixedly connected by an adhesive material. Of course, when assembling the outer ring and the inner ring, first align the registration groove of the outer ring with the preset position of the inner ring and then fix the two.

In one embodiment, a fluorescent layer is provided in at least one outer ring region of the outer ring, and a filter layer is provided in at least one inner ring region of the inner ring. The fluorescent layer and the filter layer are aligned by an alignment structure. The fluorescent layer and the reflective layer can be respectively provided in different outer ring regions of the outer ring, and different color filter layers can be provided in different inner ring regions of the inner ring. Since there is a height difference between the first surfaces of the outer ring and the inner ring themselves and they are not in the same plane, after the fluorescent layer and the color filter layer are provided, there can still be a height difference between the two.
[0042] In one embodiment, an outer connection ring is provided at the inner edge of the outer ring near the first surface of the outer ring. The surface of the outer connection ring forms a height difference with the first surface of the outer ring, and the surface of the outer connection ring is fixedly connected to the second surface of the inner ring, so that the outer ring and the inner ring rotate coaxially.

In one embodiment, a filter layer is provided in at least one outer ring region of the outer ring, and a fluorescent layer is provided in at least one inner ring region of the inner ring. The fluorescent layer and the filter layer are aligned by an alignment structure. Since there is a height difference between the first surfaces of the outer ring and the inner ring themselves and they are not in the same plane, after the fluorescent layer and the color filter layer are provided, there can still be a height difference between the two.
[0043] In one embodiment, an outer connection ring is provided at the inner edge of the outer ring near the first surface or the second surface of the outer ring, and an inner connection ring is provided at the outer edge of the inner ring near the first surface or the second surface of the inner ring. The surface of the outer connection ring is fixedly connected to the inner connection ring, so that the outer ring and the inner ring rotate coaxially, and the first surface of the outer ring and the first surface of the inner ring are coplanar, that is to say, there is no height difference between the first surface of the outer ring and the first surface of the inner ring.
[0044] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1The exploded view of the fluorescent color wheel is given in [reference], and the fluorescent color wheel 100 includes an outer ring 30, an inner ring 20, and a motor 10. The motor 10 (driving mechanism) is connected to the inner ring 20, and the outer ring 30 is coaxially connected to the inner ring 30. Among them, the outer ring 30 is a metal ring, and the outer ring 30 is divided into 4 regions. Among them, the outer ring 30 includes two fluorescent regions 310 and two reflection regions 320, and the fluorescent regions 310 are arranged at intervals through the reflection regions 320; the inner ring 20 is a color wheel, and the inner ring 20 includes 4 color filter regions 210 and 2 transmission regions 220; from Figure 2 Combined with Figure 6 It can be seen that there is an alignment groove 40 at the A position of the metal ring or the outer ring 30, and the alignment groove 40 only needs to be aligned with the gap junction at the A' position of the inner ring 20. At this time, the alignment is completed. From Figure 3 It can be known that there is an outer connection ring near the inner edge of the second surface of the outer ring 30, that is, there is a step near the inner edge of the outer ring of the second surface of the outer ring 30, and the outer connection ring is fixedly connected to the first surface of the inner ring 20. It can be seen from the figure that there is a height difference between the first surface of the outer ring 30 and the first surface of the inner ring 20, and the first surface of the outer ring 30 is higher than the first surface of the inner ring 20.
[0045] Please refer to Figure 4 And Figure 5 , from Figure 5 It can be seen that Figure 5 The structure of Figure 3 Is similar to Figure 5 , in Figure 4 , there is an outer connection ring near the inner edge of the first surface of the outer ring 30, and the outer connection ring is connected to the second surface of the inner ring 20. At this time, the first surface of the outer ring 30 is lower than the first surface of the inner ring 20. In this structure, a fluorescent layer can be provided on the first surface of the inner ring 20, and a color filter layer can be provided on the first surface of the outer ring 30. As Figure 4 Shown, there is an outer connection ring near the inner edge of the second surface of the outer ring 30, and there is an inner connection ring near the outer edge of the first surface of the inner ring 20. The surface of the outer connection ring is fixedly connected to the inner connection ring, so that the outer ring 30 and the inner ring 20 rotate coaxially, and the first surface of the outer ring 30 and the first surface of the inner ring 20 are coplanar.
[0046] Please refer to Figure 2 , Figure 6 , Figure 7 And Figure 8 , there is an outer connection ring 31 at the inner edge of the outer ring 30, there is an alignment groove 40 at the edge A of the inner ring 30, and there is an anti-fooling groove 41 at the inner edge B of the outer ring 30. From Figure 2It can be seen that as long as the alignment groove 40 is aligned with the A' position of the inner ring 20, and then it is judged whether the anti-fooling groove 41 is aligned with the B' position of the inner ring 20. If it is aligned, it proves that the assembly is correct; if not, it indicates an assembly error and needs to be realigned. To better assemble the outer ring and the inner ring, as Figure 8 shown, a raised fixing block 50 is provided at the outer edge of the inner ring 20. Figure 8 The fixing block 50 in is adapted to the anti-fooling groove 41 and can play a good role in fixing and installing. Of course, fixing blocks can also be provided at the outer edge of the inner ring 20 at positions corresponding to the alignment groove 40, so that the outer ring and the inner ring can be more stable during the assembly process.
