At present, when projection is carried out, the problem that projected patterns are not clear often exists. As a result of research, the inventors found that the reason for this problem is that, since the wall forming the light exit hole in the related art is often vertical, as shown in fig. 1, when the light of the projection light source is irradiated onto the wall forming the light exit hole, light reflected to the outside of the projection mask is easily generated, and the reflected light is further irradiated onto the projection surface to interfere with the projection pattern, so that the projection pattern is unclear.
In view of this, the embodiment of the present application provides a projection module 10, as shown in fig. 2 (where fig. 2 can be understood as a cross-sectional view), the projection module 10 includes a projection housing 101 and a projection light source 102 disposed inside the projection housing 101, the projection housing 101 includes a housing 1011, the housing 1011 is provided with a light exit hole 1012, and the projection light source 102 faces the light exit hole 1012; the area that light hole 1012 shared on the first surface A of cover 1011 is less than the area that light hole 1012 shared on the second surface B of cover 1011, first surface A is cover 1011 keeps away from projection light source 102's surface, second surface B is cover 1011 is close to projection light source 102's surface.
In order to facilitate fixing the projection housing 101 to other components during subsequent assembly of the projection module, the housing 1011 may include a pattern portion C and a fixing portion D, as shown in fig. 3. Wherein, the pattern part C may be convex for setting the light hole 1012; the fixing portion D may be disposed around the edge of the pattern portion C for fixing with other components.
The projection light source 102 is arranged inside the projection housing 101, so that after the light emitted by the projection light source 102 passes through the light outlet 1012 on the housing 1011, a light spot can be formed on the projection plane M, and the shape of the light spot corresponds to the shape of the light outlet 1012. In practical applications, to further enhance the definition of the pattern formed on the projection plane M, the projection light source 102 is preferably a smaller projection light source.
The shape of the light emitting hole 1012 can be set according to the actual viewing requirement, and may be, for example, a circle, a pentagram, a crescent, or the like.
In the embodiment of the present application, an area occupied by the light emitting hole 1012 on the first surface a of the cover 1011 is smaller than an area occupied by the light emitting hole 1012 on the second surface B of the cover 1011; that is, the light exit hole 1012 is provided so that the area occupied on the surface of the cover 1011 away from the projection light source 102 is smaller than the area occupied on the surface of the cover 1011 close to the projection light source 102. In this way, the wall forming the light exit hole 1012 is chamfered, as shown in fig. 2, from the surface of the cover 1011 away from the projection light source 102 to the surface close to the projection light source 102, the light exit hole 1012 is in a shape of a "horn". Since the wall forming the light outlet 1012 is a chamfered wall, when the light of the projection light source 102 irradiates the chamfered wall, most of the light is reflected to the inside of the cover 1011, so that the light reflected to the outside of the cover 1011 and irradiated onto the projection surface is reduced, and the interference of the reflected light on the wall forming the light outlet 1012 with the projection pattern is reduced.
It can be understood that with the projection module 10 provided in the foregoing embodiment of the present application, the projection module 10 includes a projection housing 101 and a projection light source 102 disposed inside the projection housing 101, where the projection housing 101 includes a housing 1011, a light exit hole 1012 is disposed on the housing 1011, and the projection light source 102 faces the light exit hole; light-emitting hole 1012 is in the shared area on the first surface A of the cover body 1011 is less than light-emitting hole 1012 is in shared area on the second surface B of the cover body 1011, first surface A does the cover body 1011 is kept away from the surface of projection light source 102, second surface B does the cover body 1011 is close the surface of projection light source 102. Through setting up light-emitting hole 1012 to the area that occupies on the surface of keeping away from projection light source 102 at the cover body 1011, be less than its area that occupies on the surface of the nearly projection light source 102 of cover body 1011, make and form the wall of light-emitting hole 1012 is the form of bevelling, and then shines when projection light source 102's light forms on light-emitting hole 1012's the wall, inside most light was reflected the cover body 1011, the light on the plane of projection has significantly reduced reflection to can reduce the interference of reflected light to the projection pattern on the plane of projection, make the projection pattern more clear.
To further facilitate the description of the shape of the wall forming the light outlet 1012, in one embodiment, the light outlet 1012 includes a circular hole, and the aperture of the circular hole is gradually reduced along the direction from the inside to the outside of the projection housing 101.
As shown in fig. 4, namely, the wall forming the light outlet 1012 is arranged as a chamfered wall, and the light outlet 1012 is shaped like a "horn" from the outside to the inside of the projection housing 101.
It can be understood that, with the above-mentioned solution, when the light of the projection light source 102 irradiates the chamfered wall forming the light outlet 1012, the interference of the reflected light to the projection pattern on the projection surface can be reduced, so that the projection module 10 can project a clear circular pattern. Of course, in the specific implementation, the shape of the light exit hole 1012 is not limited, and when the light exit hole 1012 has another shape, the variation of the wall forming the light exit hole 1012 can refer to the variation of the circular hole.
In order to further reduce the interference of the reflected light on the wall forming the light outlet 1012 with the projected pattern on the projection surface, in one embodiment, the thickness of the cover 1011 is such that the light from the projection light source 102 can be transmitted through the portion of the cover 1011 where the light outlet 1012 is not located.
The thickness of the cover 1011 can be understood as the distance between the first surface and the second surface of the cover 1011.
In the embodiment of the present application, the thickness of the cover 1011 is set to be such that the light from the projection light source 102 can be transmitted through the portion of the cover 1011 not provided with the light exit hole 1012, which is to be understood as setting the thickness of the cover 1011 to be a thinner thickness.
It can be understood that, with the above-mentioned solution, by setting the thickness of the cover 1011 to be a thinner thickness, on the basis that the wall forming the light exit hole 1012 is a chamfered wall, the area of the reflecting surface (chamfered wall) can be further reduced, and then the generation of reflected light can be reduced as much as possible, so that the interference of the reflected light to the projection pattern on the projection surface can be reduced.
If the cover 1011 is made thin, the light of the projection light source 102 can be transmitted through the portion of the cover 1011 where the light exit hole 1012 is not provided, and the transmitted light is irradiated on the projection surface, which may also interfere with the projection pattern on the projection surface. Thus, in one embodiment, the projection mask 101 further includes a light-shielding layer disposed on a surface of the mask body 1011 away from the projection light source 102 and covering a portion of the mask body 1011 where the light exit hole 1012 is not disposed.
Wherein, a light shielding layer is arranged on the surface of the cover body 1011 far away from the projection light source 102, and the light shielding can be realized by spraying a paint film with light shielding on the surface of the cover body 1011 far away from the projection light source 102.
It can be understood that, with the above-mentioned solution, by providing the light shielding layer on the surface of the cover 1011 away from the projection light source 102, the light of the projection light source 102 is limited from passing through the light exit hole 1012, and will not pass through the part of the cover 1011 where the light exit hole 1012 is not provided, so that the interference to the projection pattern on the projection surface is reduced, and the projection pattern is clearer.
In practical applications, in order to optimize the projection effect, the projection module can project a larger spot pattern on the projection surface within the same projection distance (the distance between the projection light source 102 and the projection surface). In one embodiment, as shown in fig. 5-1 and 5-2, the projection module 10 further includes a projection light source plate 103, wherein the projection light source plate 103 is connected to the projection housing 101; the projection light source 102 is disposed on the projection light source plate 103, and is offset from a central point of the projection light source plate 103.
The projection light source plate 103 may also be referred to as a circuit board, and various circuits may be disposed thereon to supply power to the projection light source 102. In order to stably arrange the projection light source 102 on the projection light source board 103 and to support the projection light source 102 well, the projection light source board 103 may be a rigid circuit board PCB. In practical applications, in order to prevent mosquitoes, dust, and the like from falling onto the projection light source board 103 from the light exit hole 1012 on the cover 1011, and causing poor contact, short circuit, and the like, the projection module 10 may further include a mosquito-proof cover 104. As shown in fig. 5-1 and 5-2, the mosquito shield 104 may be disposed between the projector cover 101 and the projection light source plate 103. Specifically, the mosquito-proof cover 104 may be a transparent plate material, which can prevent mosquitoes, dust, etc. from falling on the projection light source board 103, and simultaneously can reduce the blocking of the light of the projection light source 102 as much as possible. In practice, the mosquito shield 104 may be fixedly connected to the projector housing 101.
The projection light source plate 103 is connected to the projection housing 101, and an edge of the projection light source plate 103 may be connected to a fixing portion D of the housing 101. Specifically, the projection light source plate 103 and the fixing portion D of the cover 101 may be connected by screws by providing screw holes at positions corresponding to each other.
In the embodiment of the present application, a central point of the projection light source plate 103 may correspond to a central point of the pattern portion C of the cover 101, and a connection line X between the central point of the pattern portion C and the central point of the projection light source plate 103 is perpendicular to the projection light source plate 103. Then, the projection light source 102 is arranged to be offset from the center point of the projection light source board 103, which may be equivalent to that the projection center line Y of the projection light source 102 is arranged to be offset from the connecting line X, so that the distance between the projection light source 102 and at least part of the light exit holes 1012 on the cover 1011 may be reduced, and thus at least part of the spot pattern on the projection surface may be increased.
In practical application, the distance between the projection light source 102 and the light exit hole 1012 can be indirectly changed by changing the shape of the cover 101 to obtain a larger spot pattern, and the two schemes can be used either optionally or in a superimposed manner. For example, in one embodiment, a larger spot pattern is obtained by changing the shape of the cover 101, and the pattern portion C of the cover 101 may have an octagonal shape, as shown in fig. 3. Specifically, the pattern portion C of the cover 1011 is formed by an octagonal top surface and eight trapezoidal side surfaces, and the upper bottom edges of the eight trapezoidal side surfaces are connected to the sides of the octagonal top surface, respectively. The light exit apertures 1012 may be distributed over an octagonal top surface and eight trapezoidal side surfaces.
It can be understood that, by the above-mentioned solution, the pattern part of the cover 1011 is designed into an octagonal shape, and the distances between the projection light source 102 and the light emitting holes 1012 on the eight trapezoidal sides become smaller compared to the conventional hemispherical cover, so that the light emitted from the light emitting holes 1012 on the eight trapezoidal sides can project a larger pattern on the projection plane.
To further enrich the light efficiency of the projection module, in one embodiment, the projection module 10 further comprises a control element 105 and an auxiliary light source 106, as shown in fig. 5-1, the control element 105 and the auxiliary light source 106 being both arranged on the projection light source plate 103.
Wherein the auxiliary light source 106 may be disposed around the projection light source plate 103. In practical applications, the projection light source plate 103 is often matched with the shape of the projection module 10, for example, the projection module 10 has a five-pointed star shape, and the projection light source plate 103 may also be made into a five-pointed star shape. In order to facilitate the arrangement of the auxiliary light source 106 and enable the auxiliary light source 106 to achieve a uniform light emitting effect, the auxiliary light source 106 may include a plurality of sub light sources disposed around the projection light source plate 103 and surrounding the projection light source 102. More specifically, the plurality of sub-light sources may be connected to each other to form a ring, which can further improve the effect of uniform light emission.
Based on the auxiliary light source 106 and the projection light source 102, the projection module 10 may have more light emitting modes, such as only one of the projection light source 102 and the auxiliary light source 106, or both. The control element 105 may be used to control the light emission pattern.
In the embodiment of the present application, the control element 105 and the auxiliary light source 106 are both disposed on the same projection light source plate 103, which also makes the structure of the projection module 10 more compact and simple and the cost lower.
In the case where the projection light source plate 103 is provided with both the projection light source 102 and the auxiliary light source 106, it is considered that the light beams of the two may affect each other, and particularly, the auxiliary light source 106 may affect the projection light source 102, which may result in an unclear projection pattern. Thus, in one embodiment, the projection module 10 further includes a light blocking member 107, as shown in fig. 6, the light blocking member 107 is disposed between the projection light source 102 and the auxiliary light source 106, and isolates the light from the projection light source 102 and the light from the auxiliary light source 106 from each other.
It can be understood that with the above-described scheme, by providing the light blocking member 107 between the projection light source 102 and the auxiliary light source 106, light interference between the two can be reduced. During actual assembly, the upper edge of the light blocking member 107 may contact with the fixing portion D (opaque) of the cover 101, and the lower edge of the light blocking member 107 may contact with the projection light source plate 103, so that the fixing portion D of the cover 101, the light blocking member 107, and the projection light source plate 103 enclose an independent space for accommodating the auxiliary light source 106; the pattern portion C of the cover 101, the light blocking member 107 and the projection light source plate 103 enclose an independent space for accommodating the projection light source 102, so that the light emitted by the auxiliary light source 106 can be prevented from being emitted from the pattern portion C of the cover 101, and interference on the projection pattern can be avoided.
Further, in one embodiment, the light blocking member 107 includes a light blocking rib 1071, and in the case that the plurality of sub light sources are connected to each other to form a ring shape, the light blocking rib 1071 forms a ring shape and corresponds to the arrangement positions of the plurality of sub light sources.
As shown in fig. 5-1 and 5-2, the light blocking rib 1071 may be a ring of ribs protruding from the fixing portion D of the cover 101 (only a part of the ribs are shown in fig. 5-1 for the reason of viewing angle), and may be integrally formed with the fixing portion D. When the fixing portion D is assembled with the projection light source plate 103, the light blocking rib 1071 contacts the projection light source plate 103, and the projection light source 102 and the auxiliary light source 106 are spaced apart after the assembly.
Further, in one embodiment, the projection module 10 further includes a diffusion cover 108 and a decoration cover 109, the decoration cover 109 is fixedly connected to the diffusion cover 108, and the diffusion cover 108 is fixedly connected to the projection cover 101; the projection light source plate 103 is disposed between the diffusion cover 108 and the projection cover 101.
The diffusion cover 108 is a light-transmitting cover, and the decoration cover 109 is a light-shielding cover. The diffuser 108 includes a bottom E and a rim portion F having a height, and the trim cover 109 is sized to match the size of the bottom E of the diffuser 108. During assembly, the decoration cover 109 is attached to the bottom E of the diffusion cover 108, so that the edge part F of the diffusion cover 108 is exposed, and when the auxiliary light source 106 emits light, the light can penetrate out of the edge part F, and a halo effect is formed around the lamp body. Therefore, when the projection light source 102 and the auxiliary light source 106 emit light, a pattern obtained by the light of the projection light source 102 passing through the light outlet 1012 on the cover 1011 can be formed on the projection surface, and meanwhile, a halo effect generated by the light emitted by the auxiliary light source 106 can be formed around the lamp body, so that the lighting effect of the projection module 10 can be further enriched.
Based on the projection module 10 provided in the above embodiment, an embodiment of the present application further provides an assembling method of the projection module 10, including: firstly, the mosquito-proof cover 104 is fixed on the projection cover 101 through a buckle, and then the projection light source plate 103 is fixed on the projection cover 101 through a buckle; the diffusion cover 108 and the decoration cover 109 are glued and fixed in advance, and then the diffusion cover 108 and the decoration cover 109 which are well adhered are fixed on the projection cover 101 through screws, so that the assembly of the projection module 10 is completed.
In practical applications, in order to meet the increasing viewing requirements of people, a projection function may be provided to the lighting fixture, for example, a projection module is integrated into the lighting fixture, so that the lighting fixture not only can illuminate, but also can project a pattern with viewing effect to a roof ceiling. In the projection process, the projection light source needs to have a longer projection distance with a roof ceiling, and a better projection effect can be realized. Therefore, in order to satisfy the projection distance of the projection light source, the projection module is generally integrated in a specific type of lighting fixture far from the roof, such as a ceiling lamp, which greatly limits the application of the projection module in the lighting fixture.
In view of this, the present embodiment provides a luminaire 20 with a projection function, as shown in fig. 7, the luminaire 20 includes an illumination module 201, a projection module 10, and a connecting part 202, where the illumination module 201 and the projection module 10 are connected by the connecting part 202; the illumination module 201 comprises an illumination light source 2011 and a mounting component 2012, and the projection module 10 comprises a projection light source 102; the illumination light source 2011 is disposed toward the projection module 10, and the projection light source 102 is disposed toward the illumination module 201; the illumination module 201 is mounted on a target surface N by the mounting part 2012, and a distance H between the projection light source 102 and the target surface N 1 Greater than the distance H between the illumination light source 2011 and the target surface N 2 。
The lighting module 201 may be used for daily lighting, and the lighting module 201 may also be understood as the above mentioned lighting fixture. For the projection module 10, reference may be made to the above embodiments, and details are not described herein. The target surface N may be a roof ceiling.
In the embodiment of the present application, the illumination module 201 and the projection module 10 are connected by the connection part 202, so that the connection part 202 can support and fix the projection module 10 after the illumination module 201 is mounted on the target surface N by the mounting part 2012. In practical applications, the connecting member 202 may also be a hollow structure for leading wires from the illumination module 201 to the projection module 10 to supply power to the projection module 10.
In the embodiment of the present application, after the illumination module 201 is mounted on the target surface N by the mounting part 2012, the distance H between the projection light source 102 and the target surface N is determined based on the connection part 202 connecting the illumination module 201 and the projection module 10 1 Greater than the distance H between the illumination source 2011 and the target surface N 2 Therefore, even if the illumination module 201 is closer to the target surface N, the projection light source 102 can be located farther from the target surface N, and the projection distance of the projection light source 102 is increased.
In practical applications, the surface onto which the light emitted from the projection light source 102 is projected may be the same as or parallel to the target surface N. When the surface projected by the light emitted from the projection light source 102 is parallel to the target surface N, the distance between the projection light source 102 and the surface is also greater than the distance H between the illumination light source 2011 and the target surface N 2 。
