Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. Furthermore, it should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, and are not intended to limit the present disclosure. In the present disclosure, unless otherwise specified, use of the directional terms "upper" and "lower" generally refer to upper and lower, and specifically to the orientation of the drawing figures in the drawings, in the actual use or operating condition of the device; while "inner" and "outer" are with respect to the outline of the device.
The embodiment of the disclosure provides a projection device and a projection light effect device thereof. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
The present disclosure provides a projection device that can be adapted for use in home, education, work, and outdoor scenarios. Referring to fig. 1, the projection apparatus includes a light source 10 and a projection lens 20. The projection lens 20 may be a long-focus lens, a short-focus lens, an ultra-short-focus lens, and the like, and the disclosure is not limited thereto. The projection lens 20 includes a lens assembly 21 and a projection light effect device 22. The lens assembly 21 is accommodated in the projection light effect device 22, and the light source 10 is disposed in the projection light effect device 22 and emits light toward the lens assembly 21.
Referring to fig. 2 to 3, the projection light effect device 22 includes a housing 100, and a light effect component 300 and a connecting member 400 disposed in the housing 100.
The housing 100 is used for accommodating the light source 10, the lens assembly 21, the light effect assembly 300 and the connector 400. The light sources 10, the light effect components 300, and the lens components 21 are sequentially arranged in the housing 100 at intervals along the optical axis direction. The light source 10 emits a projection light toward the light effect assembly 300 and the lens assembly 21, and the projection light passes through the light effect assembly 300 and the lens assembly 21 and is projected on a projection surface such as a curtain or a wall surface. The light effect assembly 300 is movably connected to the housing 100, and is located between the light source and the lens assembly, and is mainly used for adjusting display effects of a projected picture, such as a projected picture and a projected light effect. The lens assembly 21 is located at the light-emitting end of the projection device and includes a plurality of optical assemblies for optically processing the projection light to ensure the final projection is clear and accurate.
It is understood that the light effect assembly 300 is used to shape the projection to a preset contour and/or to generate a preset light effect. Specifically, the preset contour can be realized by shading the light effect component 300, and the means for realizing the preset light effect will be described later. The light effect assembly 300 may achieve only one of the effects, or both effects simultaneously.
Referring to fig. 4, the light effect assembly 300 includes a light shielding plate 310 and a light effect plate 320. The light shielding plate 310 is provided with an imaging hole 311 with a preset contour to limit the projected picture. The light effect plate 320 is a light-transmitting plate for generating a predetermined light effect by projection, and a partial region of the surface of the light effect plate is processed by coating, sanding or engraving to show predetermined light effects such as edge feathering, background blurring and gaussian blurring. In this embodiment, the light shielding plate 310 and the light effect plate 320 are disposed opposite to each other, and in other embodiments, the light effect plate 320 may be embedded in the imaging hole 311 of the light shielding plate 310. The coating film may be coated with some films having optical functions, such as an optical filter having a filtering effect on light with a specific wavelength, and different regions of the optical filter may have different filtering effects on light, such as a transmittance of 30% for blue light in an edge region, a transmittance of 100% for blue light in a central region, and a transmittance between the central region and the edge region changing linearly or logarithmically. Alternatively, the edge region filters blue light, the central region filters red light, and the wavelength of the light filtered between the central region and the edge region varies linearly or logarithmically. Alternatively, both the transmittance and the wavelength of the filtered light may be varied.
In particular, the edge of the imaging hole 311 may be located at the inner side of the projected image at the light shielding plate 310 to define the shape and area of the projection, forming a predetermined contour thereof. In some embodiments, the contour of the imaging aperture 311 may also be adapted to the original frame of the projection, so that the projection is displayed as the original frame.
Specifically, the movement of the light effect assembly 300 relative to the housing 100 may be driven by a motor, a hydraulic device, or the like, or may be adjusted by a user.
The connecting member 400 is fixed in the housing 100 and movably connected to the light effect component 300, so that the light effect component 300 can move on the light incident side of the lens assembly 21 in the housing 100. When the light effect component 300 moves to the projection light path, the picture projected by the projection device is changed into the picture limited by the imaging hole 311 through the adjustment of the light effect component 300, and the preset light effect is presented. When the light effect component 300 moves far away from the projection light path, the projection of the projection device is not adjusted by the light effect component 300 and is presented as the original light effect of the original picture.
In other embodiments of the present disclosure, the light effect component 300 may also be movable on the light emitting side of the lens component 21, for example, in the embodiment shown in fig. 5, the light effect component 300 covers the light emitting port 101 on the outer side of the housing 100 and is movably connected with the housing 100 (the movable connection may refer to a sliding connection implemented by a structure such as a sliding slot and a sliding block, or a meshing connection implemented by a rack and pinion, which is described as an example later), and in a using process, a user may implement switching between the light effect and the picture by pulling or rotating the light effect component 300. By disposing the light effect component 300 outside the housing 100, the housing 100 does not need to dispose a space for the light effect component 300 to move, so that the space inside the housing 100 can be effectively saved, and the volume of the housing 100 can be reduced.
In still other embodiments of the present disclosure, referring to fig. 6, the light shielding plate 310 and the light effect plate 320 are respectively movable on the light emitting side and the light incident side of the lens assembly 21. The cross section area of the projection light on the light incident side of the lens assembly 21 is larger than that of the projection light on the light emergent side of the lens assembly 21, so that the light shielding plate 310 is arranged on the light incident side of the lens assembly 21 to be beneficial to cutting a picture, and the light effect plate 320 is arranged on the light emergent side of the lens assembly 21 to be beneficial to controlling the width of a blurred edge under edge blurring light effect.
The connecting member 400 is movably connected to the light effect assembly 300 in a rotating manner or a movable manner, which is not limited in this disclosure, and will be described in detail by way of example.
In some embodiments of the present disclosure, please refer to fig. 4 and 7 in combination, the connecting member 400 is a connecting plate, and a region corresponding to the light path projection is provided with a light-transmitting structure 401, in this embodiment, the light-transmitting structure 401 is specifically a light-transmitting groove, and in other embodiments, the light-transmitting structure may also be a light-transmitting structure such as a light-transmitting hole. Meanwhile, the light shielding plate 310 is movably connected with the connection member 400, and the light effect plate 320 is connected and fixed on the light shielding plate 310, is arranged corresponding to the imaging hole 311 of the light shielding plate 310, and moves together with the light shielding plate 310.
In an embodiment of the present disclosure, referring to fig. 4, the connecting member 400 includes a second connecting member 420, and the light-transmitting structure 401 is disposed on the second connecting member 420. A side of the second connecting member 420 is hinged to a side of the light effect assembly 300, and the light effect assembly 300 can be turned over on the connecting member 400 around the hinged side. In the flip structure, the second connector 420, which is a connection plate, may play a role of a limit. When the light effect component 300 is turned to the position attached to the second connecting piece 420, the imaging hole 311, the light effect plate 320 and the light transmission groove are overlapped and are all located on the light path, and the projection of the projection device penetrates through the imaging hole 311, the light effect plate 320 and the light transmission groove to finally present a preset picture and a preset light effect. When the light effect assembly 300 is flipped to a position away from the connection 400, the imaging hole 311 and the light effect plate 320 are away from the light path, leaving only the light groove in the light path. At this time, the projection of the projection device only passes through the light-transmitting structure 401, and the original picture and the original light effect are presented. In the present disclosure, the bottom side of the second connecting member 420 is hinged to the bottom side of the light effect component 300, and the bottom side of the light effect component 300 is further provided with a driver in driving connection with the light effect component 300 for driving the turning motion of the light effect component 300.
In another embodiment of the present disclosure, please refer to fig. 7 to 11 in combination, the connecting member 400 includes a first connecting member 410, the light-transmitting structure 401 is disposed on the first connecting member 410, and a sliding block 411 is disposed on one side of the light-transmitting structure 401 and intersects with the optical axis, and a sliding slot 301 is correspondingly disposed on the light-effect component 300, so that the light-effect component 300 can slide on the first connecting member 410 along the direction intersecting with the optical axis. In this embodiment, the optical component 300 slides left and right perpendicular to the optical axis, and in other embodiments, the optical component may slide up and down or slide obliquely, as long as the optical component 300 can be switched between the two states of being in the optical path and being out of the optical path, which is not limited in this disclosure. Meanwhile, in other embodiments, the first connecting member 410 may be provided with a sliding groove 301, and the light effect assembly 300 is correspondingly provided with a sliding block.
In an embodiment of the present disclosure, referring to fig. 7, the sliding groove 301 is disposed on the light shielding plate 310, and the light shielding plate 310 is slidably connected to the first connecting element 410. The light effect plate 320 is connected and fixed to the light shielding plate 310, is disposed corresponding to the imaging hole 311 of the light shielding plate 310, and moves together with the light shielding plate 310. When the light shielding plate 310 slides to the position where the light effect plate 320 coincides with the light transmission structure 401, the imaging hole 311, the light effect plate 320 and the light transmission groove coincide and are all on the light path, and the projection of the projection device passes through the imaging hole 311, the light effect plate 320 and the light transmission groove, so that a preset picture and a preset light effect are displayed finally. When the light shielding plate 310 slides to a position where the light effect plate 320 is far away from the light transmitting structure 401, the imaging hole 311 and the light effect plate 320 are far away from the light path, and only the light transmitting groove is still in the light path. At this time, the projection of the projection device only passes through the light-transmitting structure 401, and the original picture and the original light effect are presented.
In the projection light effect device 22 provided by the present disclosure, referring to fig. 7 to 16, the number of the light effect plates 320 may be multiple and are mounted on the fixing plate 330, and the number of the imaging holes 311 on the light shielding plate 310 is also multiple and corresponds to the light effect plates 320 (which may be many-to-many, or single-to-many, or multiple-to-single). The light shielding plate 310 and the fixing plate 330 may be coupled to the housing 100 to move simultaneously or independently, for example, both may be rotatably or slidably coupled to the housing 100, one may be rotatably coupled to the housing 100, and the other may be slidably coupled to the housing 100. The manner of implementing the rotational connection or the sliding connection may be implemented by the connection member 400 of the present embodiment. In particular, in some of the examples below.
In another embodiment of the present disclosure, please refer to fig. 8 in combination, the sliding groove 301 is disposed on the light shielding plate 310, and the light shielding plate 310 is slidably connected to the first connecting element 410. Meanwhile, the light shielding plate 310 is provided with a plurality of imaging holes 311 with different outlines so as to present different frames.

Each imaging hole 311 is arranged at intervals along the sliding direction of the light shielding plate 310, each imaging hole 311 is correspondingly covered and connected with a light effect plate 320, and each light effect plate 320 makes the projection generate different preset light effects, for example, in the embodiment shown in fig. 8, two light effect plates 320 can respectively generate two light effects of gaussian blur and edge feathering. In the using process, the light shielding plate 310 is slid, when the imaging hole 311, the light effect plate 320 and the light transmission groove are overlapped, the projection of the projection device passes through the imaging hole 311, the light effect plate 320 and the light transmission groove, and finally, a preset picture and a preset light effect are displayed. Compared with the scheme, the scheme of the embodiment can present various picture frames and light effects, and the projection presenting modes of the projection equipment are remarkably enriched, so that the projection equipment can be suitable for more scenes.
In another embodiment of the present disclosure, please refer to fig. 9 to 11 in combination, the sliding groove 301 is disposed on the light shielding plate 310, and the light shielding plate 310 is slidably connected to the first connecting member 410.

However, in the present embodiment, the light effect assembly 300 further includes a fixing plate 330 disposed opposite to the light shielding plate 310. The light effect plate 320 is disposed on the fixing plate 330, and the fixing plate 330 is also slidably connected with the first connecting member 410 along the sliding direction of the light shielding plate 310, so that the fixing plate 330 and the light shielding plate 310 can slide relatively independently. The fixing plate 330 has a shape having the same size as or close to the light shielding plate 310 and is slidably coupled to the first coupling member 410.

In the using process, the light shielding plate 310 and the fixing plate 330 can be respectively slid, when the imaging hole 311, the light effect plate 320 and the light transmission groove coincide, the projection of the projection device passes through the imaging hole 311, the light effect plate 320 and the light transmission groove, and finally the preset picture and the preset light effect are displayed. Compared with the scheme, the scheme of the embodiment can present more pictures and light effects, different pictures and light effects can be freely combined, and the projection presenting mode of the projection equipment is remarkably enriched, so that the projection equipment can be suitable for more scenes.
In other embodiments of the present disclosure, referring to fig. 12 to 16, the connecting member 400 includes a third connecting member 430. The third connecting member 430 is a connecting plate provided with the light-transmitting structure 401, and a connecting shaft 432 along the optical axis direction is further provided at one side of the light-transmitting structure 401.

The light shielding plate 310 is sleeved on the connecting shaft 432 and rotates around the connecting shaft 432. When the light shielding plate 310 rotates to the position where the light effect plate 320 coincides with the light transmission structure 401, the imaging hole 311, the light effect plate 320 and the light transmission groove coincide and are all on the light path, and the projection of the projection device penetrates through the imaging hole 311, the light effect plate 320 and the light transmission groove, so that a preset picture and a preset light effect are displayed finally. When the light shielding plate 310 rotates to a position where the light effect plate 320 is far away from the light transmitting structure 401, the imaging hole 311 and the light effect plate 320 are far away from the light path, and only the light transmitting groove is still in the light path. At this time, the projection of the projection device only passes through the light-transmitting structure 401, and the original picture and the original light effect are presented.
