Description

Technical Field

[0001] This invention relates to a method for adjusting the position of a light source system, a projection device, and a light-emitting unit. Background Technology

[0002] Existing projectors using blue lasers with phosphor wheels cannot achieve the DCI-P3 color gamut. Adding a red laser to the projector architecture allows the projected image to reach the DCI-P3 color gamut. However, as the number of light sources increases, the precision of their placement affects the uniformity of the projected image; therefore, the precision required for light source placement in projectors increases accordingly.

[0005] Other objects and advantages of the present invention can be further understood from the technical features disclosed herein.

[0006] To achieve one or more of the above objectives, or other objectives, an embodiment of the present invention provides a light source system configured on a light combining base, comprising a light source module and a positioning module. The light source module provides at least one color light beam. The light source module includes a light-emitting unit and a heat dissipation module. The light-emitting unit is fixed to the heat dissipation module. The heat dissipation module has a first locking hole extending along a first extending direction. The positioning module includes a frame and a first positioning component. The first positioning component corresponds to the first locking hole. The frame is fixed to the light combining base and located between the light combining base and the light source module. The first positioning component includes a first positioning element and a first limiting member. The first limiting member is used to fix to the frame to limit a portion of the first positioning element between the first limiting member and the frame. The first positioning element passes through the frame along the first extending direction and is screwed into the first locking hole of the heat dissipation module. The portion of the first positioning element is adapted to have different distances relative to the heat dissipation module, corresponding to different positions of the light-emitting unit relative to the light combining base in the first extending direction.

[0007] To achieve one or more of the above-mentioned objectives, or other objectives, an embodiment of the present invention provides a projection device, comprising a light source system, a light combining base, a light transmission module, an optomechanical module, and a lens module. The light source system is disposed on the light combining base. The light transmission module is disposed within the light combining base. The light source system is used to provide at least one color light beam. The light transmission module is disposed on the transmission path of the at least one color light beam. The light transmission module is used to transmit the at least one color light beam and form an illumination beam. The optomechanical module is disposed on the transmission path of the illumination beam. The optomechanical module is used to convert the illumination beam into an image beam. The lens module is disposed on the transmission path of the image beam and is used to project the image beam out of the projection device. The light source system includes a light source module and a positioning module. The light source module is used to provide at least one color light beam. The light source module includes a light-emitting unit and a heat dissipation module. The light-emitting unit is fixed on the heat dissipation module. The heat dissipation module has a first locking hole extending along a first extending direction. The positioning module includes a frame and a first positioning component. The first positioning component corresponds to the first locking hole. The frame is fixed to the light-combining base and located between the light-combining base and the light source module. The first positioning assembly includes a first positioning element and a first limiting member. The first limiting member is used to fix the frame to limit a portion of the first positioning element between the first limiting member and the frame. The first positioning element passes through the frame along a first extending direction and is screwed into a first locking hole of the heat dissipation module. The portion of the first positioning element is adapted to have different distances relative to the heat dissipation module, corresponding to different positions of the light-emitting unit relative to the light-combining base in the first extending direction.

[0008] To achieve one, some, or all of the above objectives, or other objectives, an embodiment of the present invention provides a method for adjusting the position of a light-emitting unit, comprising the following steps: Fixing the light-emitting unit onto a heat dissipation module. Fixing a frame onto a light-combining base. Inserting a first positioning element from a first positioning assembly through the frame along a first extending direction and screwing it into a first locking hole in the heat dissipation module, and fixing a first limiting member from the first positioning assembly to the frame, such that a portion of the first positioning element is limited between the first limiting member and the frame. Rotating the first positioning element to move the heat dissipation module along the first extending direction relative to the light-combining base, thereby adjusting the position of the light-emitting unit relative to the light-combining base.

[0009] Based on the above, this invention adjusts the position of the light-emitting unit relative to the light-absorbing base by rotating the first positioning element, thereby moving the heat dissipation module along the first extension direction. Therefore, the position of the light-emitting unit can be easily adjusted to the correct position in the optical path design, allowing the adjustment method of the light source system, projection device, and light-emitting unit to provide good lighting or projection effects. Furthermore, since this invention adds a frame between the existing light-absorbing base and heat dissipation module, and adjusts the position of the light-emitting unit using the first positioning element, it not only reduces processing difficulty but also lowers production costs.

[0075] The foregoing descriptions and other technical contents, features, and effects of this invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the accompanying drawings. The directional terms used in the following embodiments, such as up, down, left, right, front, or back, are merely for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0076] Figure 1 This is a block diagram of a projection device according to an embodiment of the present invention. Please refer to... Figure 1An embodiment of the present invention provides a projection device 10, which includes a light source system 100, a light combining base 200, a light transmission module 300, an optical engine module 400, and a lens module 500. The light source system 100 is disposed on the light combining base 200. The light transmission module 300 is disposed within the light combining base 200. The light source system 100 provides at least one color light beam L. The light transmission module 300 is disposed on the transmission path of the at least one color light beam L and is used to transmit the at least one color light beam L and form an illumination beam IL. The optical engine module 400 is disposed on the transmission path of the illumination beam IL and is used to convert the illumination beam IL into an image beam IB. The lens module 500 is disposed on the transmission path of the image beam IB and is used to project the image beam IB out of the projection device 10.

[0077] For more details, please also refer to... Figure 1 and Figure 2 . Figure 2 This is a perspective view of a portion of a projection device according to an embodiment of the present invention. In this embodiment, the light-combining base 200 has a light inlet 210 and a receiving space, and the receiving space of the light-combining base 200 is connected to the outside through the light inlet 210. A light source system 100 is disposed on the light-combining base 200 and covers the light inlet 210, allowing at least one color light beam L provided by the light source system 100 to pass through the light inlet 210 and enter the light-combining base 200. A light transmission module 300 is disposed in the receiving space of the light-combining base 200, and may include multiple light transmission elements. Light transmission elements may be, for example, lenses, beam splitters, mirrors, etc., and the present invention does not limit the number or type of light transmission elements. In one embodiment, the light inlet 210 of the light-combining base 200 may be further provided with an optical component 212 (e.g., a lens or diffuser covering the light inlet 210 of the light-combining base 200). In one embodiment, a dustproof component may be configured between the light source system 100 (such as frame 122) and the light combining base 200. The dustproof component surrounds the light inlet 210 of the light combining base 200 and exposes the light inlet 210 and optical components 212 of the light combining base. By setting the dustproof component, the dustproof effect of the light source system 100 and the light combining base 200 can be improved.

[0078] In other embodiments, the light transmission module 300 may further include a phosphor wheel. The phosphor wheel is used to convert the color beam L or other color beams from the light source system 100 into color beams with different wavelengths. The aforementioned light transmission element is used to transmit the color beam L, other color beams, and the converted beams with different wavelengths. The light transmission module 300 may also include a filter. The filter is used to be disposed in the transmission path of the aforementioned color beam L, other color beams, and converted beams. Therefore, the aforementioned color beam L, other color beams, and converted beams can form an illumination beam IL after passing through the filter. Furthermore, the light transmission module 300 may also include a light diffusion element, which is used to be disposed in the transmission path of the aforementioned color beam L, other color beams, or converted beams.

[0079] In this embodiment, the optomechanical module 400 may include a homogenizing element 600 and at least one optical valve. The homogenizing element 600 is disposed in the transmission path of the illumination beam IL. The homogenizing element 600 is, for example, an integration rod, a lens array, or other optical elements with light homogenization effects, but the invention is not limited thereto. The optical valve is disposed in the transmission path of the illumination beam IL to convert the illumination beam IL into an image beam IB. The optical valve is, for example, a reflective light modulator such as a digital micromirror device (DMD) or a liquid-crystal-on-silicon panel (LCOS). In other embodiments, the optical valve may also be a transparent liquid crystal panel, an electro-optic modulator, a magneto-optic modulator, an acousto-optic modulator (AOM), or other types of spatial light modulators (SLMs). This invention does not limit the type or variety of optical valves.

[0080] In this embodiment, the lens module 500 may be a combination of one or more optical lenses having diopter, such as various combinations of non-planar lenses including biconcave lenses, biconvex lenses, concave-convex lenses, convex-concave lenses, plano-convex lenses, and plano-concave lenses. The present invention does not limit the type or form of the lens module 500.

Figure 5D yes Figure 5A A schematic diagram from another perspective.

[0082] Please refer to Figures 2 to 5D In this embodiment, the light source system 100 includes a light source module 110 and a positioning module 120. The light source module 110 is used to provide at least one color beam L. The color beam L can be a red light, green light, blue light beam, mixed light beam, other light beams, or non-primary color beams. The present invention does not limit the number or color of the color beam L.

[0083] In this embodiment, the light source module 110 includes a light-emitting unit 112 and a heat dissipation module 114, such as... Figure 5D As shown. The light-emitting unit 112 is fixed on the heat dissipation module 114 and is used to emit at least one color light beam L. The light-emitting unit 112 may include, for example, one or more light-emitting diodes (LEDs), one or more laser diodes (LDs), or a combination of the above two light sources.

[0084] In this embodiment, the heat dissipation module 114 has a first extending direction A1 (e.g., Figure 3 A first locking hole 114a extends (parallel to the Y-axis). The positioning module 120 includes a frame 122 and a first positioning component 124. The frame 122 can be made of plastic or metal. When the frame 122 is made of plastic, it can further provide heat insulation to isolate the light source module 110 from the light combining base 200, reduce heat conduction from the light combining base 200 to the light source module 110, and reduce the load on the heat dissipation module 114 in the light source module 110. However, the present invention is not limited to this. The first positioning component 124 corresponds to the first locking hole 114a. The frame 122 is fixed on the light combining base 200 and located between the light combining base 200 and the light source module 110. The first positioning component 124 includes a first positioning element 124a and a first limiting member 124b. The first limiting member 124b is used to fix the frame 122 to limit a portion of the first positioning element 124a between the first limiting member 124b and the frame 122. The first positioning element 124a passes through the frame 122 along the first extending direction A1 and is screwed into the first locking hole 114a of the heat dissipation module 114. The portion of the first positioning element 124a is adapted to have different distances relative to the heat dissipation module 114, correspondingly causing the light-emitting unit 112 to have different positions relative to the light-combining base 200 in the first extending direction A1.

[0085] In this embodiment, the heat dissipation module 114 also has a second extending direction A2 (e.g., Figure 3 A second locking hole 114b extends in a direction parallel to the X-axis. The first extending direction A1 is perpendicular to the second extending direction A2. The positioning module 120 also includes a second positioning component 126. The second positioning component 126 corresponds to the second locking hole 114b. The second positioning component 126 includes a second positioning element 126a and a second limiting member 126b. The second limiting member 126b is used to fix to the frame 122 to limit a portion of the second positioning element 126a between the second limiting member 126b and the frame 122. The second positioning element 126a passes through the frame 122 along the second extending direction A2 and is screwed into the second locking hole 114b of the heat dissipation module 114. The portion of the second positioning element 126a is adapted to have different distances relative to the heat dissipation module 114, corresponding to different positions of the light-emitting unit 122 relative to the light-combining base 200 in the second extending direction A2.

[0086] In this embodiment, the frame 122 includes a first sidewall 122a and a second sidewall 122b that are perpendicular to each other, such as Figure 4 As shown. The first sidewall 122a has a first through hole H1, and the second sidewall 122b has a second through hole H2. A first limiting member 124b and a second limiting member 126b are respectively fixed on the first sidewall 122a and the second sidewall 122b. The first positioning element 124a is used to pass through the first through hole H1 in a first extending direction A1 and screw into the first locking hole 114a. The second positioning element 126a is used to pass through the second through hole H2 in a second extending direction A2 and screw into the second locking hole 114b.

[0087] In this embodiment, the first limiting member 124b has a first limiting through hole H3, and the second limiting member 126b has a second limiting through hole H4. The first positioning element 124a includes a first head 124a-1 and a first stud 124a-2 connected to each other. The second positioning element 126a includes a second head 126a-1 and a second stud 126a-2 connected to each other. The first positioning element 124a and the second positioning element 126a are, for example, screws, but the invention is not limited thereto. When the first stud 124a-2 of the first positioning element 124a is screwed into the first locking hole 114a, the first head 124a-1 is rotatably limited between the first limiting member 124b and the first sidewall 122a, and the first limiting through hole H3 of the first limiting member 124b exposes a portion of the first head 124a-1. When the second stud 126a-2 of the second positioning element 126a is screwed into the second locking hole 114b, the second head 126a-1 is rotatably limited between the second limiting member 126b and the second side wall 122b, and the second limiting through hole H4 of the second limiting member 126b exposes a portion of the second head 126a-1.

[0088] Specifically, the first limiting through hole H3 of the first limiting member 124b only exposes a portion of the first head 124a-1 (e.g. Figure 4 The cross-shaped groove of the second limiting member 126b exposes only a portion of the second head 126a-1 without fully exposing the first head 124a-1, allowing the exposed portion of the first head 124a-1 to be driven and rotated to simultaneously limit the first positioning element 124a. Similarly, the second limiting through-hole H4 of the second limiting member 126b exposes only a portion of the second head 126a-1 (e.g., the cross-shaped groove of the second limiting member 126b). Figure 4 The cross-shaped groove is not exposed, so that the exposed portion of the second head 126a-1 can be driven to rotate, thereby simultaneously achieving the function of limiting the second positioning element 126a.

[0089] Since the first limiting member 124b is fixed on the first side wall 122a, the first head 124a-1 of the first positioning element 124a is limited between the first limiting member 124b and the first side wall 122a. Therefore, when the first positioning element 124a rotates, the first positioning element 124a will not move along the first extension direction A1. Instead, it will drive the heat dissipation module 114, which is screwed with the first positioning element 124a, to move in the first extension direction A1 through the first stud 124a-2. Similarly, since the second limiting member 126b is fixed on the second side wall 122b, the second head 126a-1 of the second positioning element 126a is limited between the second limiting member 126b and the second side wall 122b. Therefore, when the second positioning element 126a rotates, the second positioning element 126a will not move along the second extension direction A2. Instead, it will drive the heat dissipation module 114 screwed with the second positioning element 126a to move in the second extension direction A2 through the second stud 126a-2.

[0090] In this way, the first head 124a-1 of the first positioning element 124a can be rotated through the first limiting through hole H3 of the first limiting member 124b, thereby changing the distance between the first head 124a-1 of the first positioning element 124a and the heat dissipation module 114, and thus adjusting the position of the light-emitting unit 112 fixed on the heat dissipation module 114 in the first extending direction A1. Similarly, the second head 126a-1 of the second positioning element 126a can be rotated through the second limiting through hole H4 of the second limiting member 126b, thereby changing the distance between the second head 126a-1 of the second positioning element 126a and the heat dissipation module 114, and thus adjusting the position of the light-emitting unit 112 fixed on the heat dissipation module 114 in the second extending direction A2.

[0091] In this embodiment, as Figure 5A and Figure 5DAs shown, the heat dissipation module 114 has multiple limiting holes 114c. The limiting holes 114c can be located at a corner or other suitable position on the substrate 114d of the heat dissipation module 114. Furthermore, the heat dissipation module 114 may also have at least one heat pipe 114e and / or a heat dissipation fin assembly 114f disposed on the substrate 114d for dissipating heat from the light-emitting unit 112 of the light source module 110. Specifically, at least one heat pipe 114e and / or the heat dissipation fin assembly 114f is disposed on one surface of the substrate 114d, while the light-emitting unit 112 is disposed on another surface of the substrate 114d opposite to the stated surface. The light source module 110 also includes multiple locking components 116. The multiple locking components 116 are respectively used to pass through the multiple limiting holes 114b to lock the light source module 110 onto the frame 122. In one embodiment, a dustproof component may be configured between the frame 122 and the light-emitting unit 112. The dustproof component surrounds the light-emitting unit 112 and exposes the light-emitting unit 112. The dustproof component can improve the dustproof effect of the light source system 100 and the light-combining base 200.

[0092] In this embodiment, each of the plurality of locking components 116 includes a protective member 116a, an elastic member 116b, and a fixing member 116c. The elastic member 116b may be a C-type spring, such as... Figure 5C As shown. The fastener 116c passes through the corresponding limiting hole 114c and is locked to the frame 122. The fastener 116c passes through the elastic member 116b and the protective member 116a. The protective member 116a is positioned on the side of the limiting hole 114c away from the frame 122. The elastic member 116b is positioned on the side of the protective member 116a away from the frame 122.

[0093] In this embodiment, each of the plurality of limiting holes 114c has an inner diameter D1. The diameter D2 of the fixing member 116c is smaller than the inner diameter D1 of the limiting hole 114c, and the outer diameter D3 of the protective member 116a is larger than the inner diameter D1 of the limiting hole 114c, such as... Figure 5B As shown.

[0094] In this embodiment, the protective member 116a has a through hole H5. The diameter D4 of the through hole H5 is larger than the diameter D2 of the fixing member 116c. That is, there is a gap between the fixing member 116c, the through hole H5, and the limiting hole 114c. The gap provides space for the heat dissipation module 114 (and the light source module 110) to move, so that (when rotating the first positioning element 124a or the second positioning element 126a) the heat dissipation module 114 (and the light source module 110) can move relative to the frame 122 through the gap.

[0095] In this embodiment, the frame 122 has an entrance aperture 122c. The entrance aperture 122c is used to allow at least one color light beam L to pass through.

[0096] As described above, the first positioning component 124 and the second positioning component 126 drive the light-emitting unit 112 fixed on the substrate 114d to move relative to the light-combining base 200, so that the light-emitting unit 112 and the light-combining base 200 are not limited by their own structure and can be quickly and accurately aligned, allowing the colored light beam L from the light-emitting unit 112 to accurately pass through the light inlet 210 of the light-combining base 200. At the same time, since the alignment between the light source module 110 and the light-combining base 200 can be performed by the positioning module 120, the influence of component tolerances on the illumination beam of the light source module 110 and the light-combining base 200 can be greatly reduced, and the requirements for component tolerances can be reduced, thereby reducing the purchase cost of components.

[0097] Figure 6 This is a flowchart of a method for adjusting the position of a light-emitting unit according to an embodiment of the present invention. Please refer to...

[0106] Figure 10 This is a schematic diagram of a light source system according to an embodiment of the present invention. Please refer to... Figure 10In this embodiment, the light source module 110 includes light-emitting units 112R and 112B. Specifically, light-emitting unit 112R can be disposed on substrate 114d as in any of the above embodiments and connected to light-combining base 200 through frame 122, while light-emitting unit 112B can be disposed on another substrate as in any of the above embodiments and connected to light-combining base 200 through another frame 122. In this embodiment, light-combining base 200 has light inlets 210a and 210b respectively corresponding to light-emitting units 112R and 112B. Optical components 212a and 212b can be further disposed on light inlets 210a and 210b, wherein optical component 212a is a diffuser and optical component 212b is a lens, but is not limited thereto. The light-combining base 200 has a housing space equipped with multiple light transmission elements 214a-214f, of which light transmission elements 214a and 214b are beam splitters, and light transmission elements 214c-214f are lenses, but are not limited thereto. In addition, the housing space of the light-combining base 200 also houses a phosphor wheel PW and a filter CW. In this embodiment, the light source module 110 does not include optical components such as beam splitters or reflectors; therefore, the light-emitting units 112R and 112B can be aligned and adjusted relative to the light-combining base 200. In this embodiment, the red light beam emitted by the light-emitting unit 112R sequentially passes through the optical component 212a, the light transmission elements 214a and 214f, and the filter CW to reach the light outlet of the light-combining base 200 (not shown in the figure), and then enters the light inlet of the light-diffusing element 600 in the optomechanical module 400. The blue light beam emitted by the light-emitting unit 112B passes sequentially through optical components 212b, light transmission elements 214c, 214a, 214d, and 214e to reach the phosphor wheel PW. Part of the blue light beam is converted into a yellow or green light beam and passes sequentially through light transmission elements 214e, 214d, 214a, and 214f ​​from the phosphor wheel PW, and is filtered in the filter CW. The yellow light beam is filtered into a red light beam, and the green light beam is filtered into a green light beam with a relatively pure wavelength. The red or green light beam emitted through the filter CW is transmitted to the light outlet of the light combining base 200 and enters the light inlet of the light homogenizing element 600 in the optomechanical module 400. In addition, another part of the blue light beam emitted by the light-emitting unit 112B is reflected by the phosphor wheel PW and passes through the light transmission elements 214e, 214d, 214a, 214f ​​and the filter CW in sequence to reach the light outlet of the light combining base 200 and enter the light inlet of the light homogenizing element 600 in the optomechanical module 400.

[0107] In summary, this invention, by fixing the light-emitting unit to the heat dissipation module, fixing the frame to the light-combining base, and inserting the first positioning element of the first positioning assembly through the frame along the first extending direction and screwing it into the first locking hole of the heat dissipation module, and fixing the first limiting member of the first positioning assembly to the frame, limits a portion of the first positioning element between the first limiting member and the frame. Therefore, when the first positioning element is rotated, the heat dissipation module can be moved relative to the light-combining base along the first extending direction to adjust the position of the light-emitting unit relative to the light-combining base, so that the position of the light-emitting unit can be adjusted to the correct position in the optical path design. Therefore, the light source system, projection device, and position adjustment method of the light-emitting unit of this invention can provide good lighting or projection effects. Moreover, the embodiment of this invention, by adding a frame between the existing light-combining base and heat dissipation module, and adjusting the position of the light-emitting unit by means of the first positioning element, not only reduces the processing difficulty but also reduces production costs.
