Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 7, the embodiment of the invention discloses a projection lamp head device 100 of a lighting fixture, and the disclosed projection lamp head device 100 includes a first housing 110, a first light emitter 120, and a dimming component 130.

The first housing 110 is used to provide a mounting base for some other components of the projection head assembly 100 (e.g., the first light emitter 120, the dimming component 130) and also to provide protection for these components from damage.

The first light emitter 120 is a projection light source of the projection lamp head apparatus 100, and emits a first light ray. The first light emitter 120 is disposed in the first housing 110. Specifically, the first light emitter 120 may be fixed within the first housing 110.

The dimming member 130 is provided on the first housing 110. Specifically, the dimming member 130 may be fixed to the first housing 110. The dimming component 130 can adjust the first light emitted by the first light emitter 120, the dimming component 130 includes a light shielding region 131 and a light transmitting region 132, the light shielding region 131 is a light-tight region, and the first light emitted by the first light emitter 120 can be projected onto the dimming component 130. Wherein, part of the first light is projected to the light-shielding region 131. Since the light-shielding region 131 is opaque, the first light projected to the light-shielding region 131 can be shielded by the light-shielding region 131 and cannot be emitted out of the projection lamp head device 100. Another portion of the first light is projected to the light transmissive region 132. Since the light-transmitting region 132 is capable of transmitting light, the first light transmitted through the light-transmitting region 132 can be projected to the outside of the projection head apparatus 100.

In the embodiment of the invention, the first end of the first casing 110 is provided with the first light outlet 110a, and the first light projected by the first light emitter 120 can pass through the light-transmitting region 132 and the first light outlet 110a and can form a light spot in the same shape as the light-transmitting region 132 in the projection region. In a specific design process, the light-transmitting area 132 can have a preset shape, so that the final light spot is an illumination pattern with the preset shape, and the decoration purpose is achieved.

The dimming component 130 may be a film with a pattern having a preset shape, and the first light projected by the first light emitter 120 can penetrate through the light-transmitting area 132 in the film to form a light spot having the same shape as the light-transmitting area 132 in the film, and the pattern formed by different films is different. Specifically, the projection lamp head device 100 may be configured with films of various patterns, and a user may change the films, thereby implementing different light spot patterns.

The projection lamp head device 100 of the lighting fixture disclosed in the embodiment of the present invention improves the structure of the lighting fixture in the background art, so that the first light emitter 120 is disposed in the first housing 110, and the light adjusting member 130 including the light transmitting area 132 and the light shielding area 131 is disposed on the first housing 110, and the first light projected by the first light emitter 120 can be projected out of the first housing 110 through the light adjusting member 130 and the first light outlet 110 a. Since the light shielding region 131 of the light adjusting member 130 can prevent a portion of the first light from passing through, and the light transmitting region 132 can allow another portion of the first light to pass through, the first light can finally form a light spot having the same shape as that of the light transmitting region 132 in the projection region, and the light spot has a predetermined shape, so as to form a predetermined pattern, thereby playing a role of decoration through projection.

Therefore, the projection lamp holder device 100 of the illumination lamp disclosed in the embodiment of the invention can form the illumination pattern with the same shape as the light-transmitting area 132 in the projection area, thereby realizing the functions of a rich illumination lamp, and further solving the problems of poor decoration and single function of the existing illumination lamp.

The projection lamp head device 100 disclosed in the embodiment of the invention may further include a second light emitter 140, the second light emitter 140 is an illumination light source for illumination, the second light emitter 140 is disposed in the first housing 110, the second end of the first housing 110 may be provided with a second light outlet 110b, and a second light projected by the second light emitter 140 may be projected to the outside of the first housing 110 through the second light outlet 110b, so as to implement illumination. That is, the first light emitted from the first light emitter 120 is mainly used to form a decorative illumination pattern, and the second light emitted from the second light emitter 140 is mainly used for illumination. In this case, the projection lamp head device 100 disclosed in the embodiment of the present invention has both a good illumination effect and a good decoration effect.

Certainly, the first light ray and the second light ray do not interfere with each other as much as possible to avoid the influence on the decoration, and based on this, the orientations of the first light outlet 110a and the second light outlet 110b are different. Under the condition, the projection lamp head device 100 can project light rays in different directions through the first light emitter 120 and the second light emitter 140, the first light rays projected by the first light emitter 120 can project light spots with the same shape as the light transmission area 132 in the projection area through the dimming component 130, the second light emitter 140 can be only used for illumination, and further the projection lamp head device 100 can achieve the function of normal brightness illumination, the decoration function is further improved, and further the structure hierarchy of the projection lamp head device 100 is rich, and the function is rich.

In an alternative scheme, the first light emitter 120 and the second light emitter 140 may be disposed opposite to each other, the first light emitter 120 projects a first light toward a first direction, and the second light emitter 140 projects a second light toward a second direction through the second light outlet 110b, where the first direction is opposite to the second direction. In this case, the direction of the first light outlet 110a is opposite to the direction of the second light outlet 110b, so as to achieve the purpose of better avoiding the mutual influence between the first light and the second light.

In a specific use, the lighting fixture may be mounted on a ceiling, and the ceiling may be used as the projection area, and the projection head apparatus 100 may form a light spot on the ceiling in the same shape as the light-transmitting area 132 during operation. The second light emitting body 140 may project a second light toward the indoor ground, thereby providing illumination for the user.

In the projection lamp head device 100 disclosed in the embodiment of the present invention, the lighting device may include a control chip, and the control chip may control the first light emitter 120 and the second light emitter 140 to be turned on or turned off simultaneously. Certainly, in order to achieve a better decoration effect, the control chip can control the first light emitter 120 to be turned on and simultaneously control the second light emitter 140 to be turned off, so that only light spots playing a decoration role are reserved indoors, a user can feel a better decoration atmosphere, and the indoor environment atmosphere is further adjusted.

The projection lamp head device 100 disclosed by the embodiment of the invention further comprises a support frame 150, and the support frame 150 can be used for supporting some components in the projection lamp head device 100, so as to provide mounting positions for the components, and further facilitate the mounting of the components. The first housing 110 has a first inner cavity 110c, and the first light emitter 120 and the second light emitter 140 are disposed in the first inner cavity 110 c.

As described above, the first light projected by the first light emitter 120 can be emitted through the first light outlet 110a, the second light projected by the second light emitter 140 can be emitted through the second light outlet 110b, and the first housing 110 has the first inner cavity 110c, so that the first light outlet 110a and the second light outlet 110b are both communicated with the first inner cavity 110 c.

In the embodiment of the present invention, the first light emitter 120 and the second light emitter 140 are both disposed in the first inner cavity 110c, and the first light emitter 120 and the second light emitter 140 are disposed in various manners in the first housing 110. In an alternative scheme, the supporting frame 150 may be fixed in the first inner cavity 110c, and the supporting frame 150 may divide the first inner cavity 110c into a first sub-cavity 110c1 and a second sub-cavity 110c2, and the first sub-cavity 110c1 and the second sub-cavity 110c2 may respectively house some components of the projection lamp head apparatus 100.

In particular, the first light emitter 120 may be disposed in the first sub-cavity 110c1, and the second light emitter 140 may be disposed in the second sub-cavity 110c 2. That is to say, the first light emitter 120 and the second light emitter 140 can be placed by the support frame 150, and at the same time, the first light emitter 120 and the second light emitter 140 can be respectively arranged in the first sub-cavity 110c1 and the second sub-cavity 110c2 which are isolated from each other, so that the first light ray projected by the first light emitter 120 is emitted from the first light outlet 110a through the first sub-cavity 110c1, and the second light ray projected by the second light emitter 140 is emitted from the second light outlet 110b through the second sub-cavity 110c2, and because the first sub-cavity 110c1 and the second sub-cavity 110c2 are isolated from each other, the structure can better avoid the mutual interference between the first light ray and the second light ray.

In a specific operation process, the first light emitter 120 and the second light emitter 140 generate a large amount of heat, which may affect the service life of the first light emitter 120 and the second light emitter 140, and may also cause the temperature of the projection lamp head device 100 to be higher. Based on this, an optional scheme, the support frame 150 may be a metal heat dissipation structure, and the metal heat dissipation structure can dissipate heat generated by the first light emitter 120 and the second light emitter 140 relatively quickly, thereby facilitating to prolong the service life of the first light emitter 120 and the second light emitter 140, and being beneficial to cooling the projection lamp head device 100. In a further technical scheme, the first light emitter 120 and the second light emitter 140 can be mounted on the support frame 150, so that heat generated by the first light emitter 120 and the second light emitter 140 can be better transferred to the support frame 150, and a more efficient heat dissipation purpose is achieved.

In order to facilitate power supply to the first and second

light emitters

120 and 140 and installation of the first and second

light emitters

120 and 140, in an embodiment of the present invention, the projection head apparatus 100 may further include a first circuit board 160 and a second circuit board 170, and the first circuit board 160 and the second circuit board 170 may respectively supply power to the first and second

light emitters

120 and 140. Specifically, the first light emitter 120 may be disposed on the first circuit board 160, the second light emitter 140 may be disposed on the second circuit board 170, the first circuit board 160 is disposed on a surface of the supporting bracket 150 facing the first sub-cavity 110c1, and the second circuit board 170 is disposed on a surface of the supporting bracket 150 facing the second sub-cavity 110c 2. In this way, the first circuit board 160 may serve as a power source to supply power to the first light emitters 120, so that the first light emitters 120 may project first light with sufficient brightness. Meanwhile, the first circuit board 160 provides a mounting position for the first light emitter 120. Similarly, the second circuit board 170 serves as a power supply device for supplying power to the second light emitter 140 and providing a mounting position for the second light emitter 140.

In the embodiment of the present invention, the structure of the supporting frame 150 may be various. In an alternative solution, the supporting frame 150 may include a substrate 151 and a supporting protrusion 152 disposed on the substrate 151, the supporting protrusion 152 extends from the substrate 151 to the second sub-cavity 110c2, the first circuit board 160 is disposed on a surface of the substrate 151 facing away from the supporting protrusion 152, and the second circuit board 170 is disposed on the supporting protrusion 152. Substrate 151 separates first interior cavity 110c into first subchamber 110c1 and second subchamber 110c 2.

The supporting frame 150 with the above structure can form a larger interval between the first circuit board 160 and the second circuit board 170, so that the occurrence of thermal influence caused by too close proximity between the first circuit board 160 and the second circuit board 170 can be avoided.

In order to further improve the heat dissipation performance of the projection lamp head device 100, in an alternative scheme, the substrate 151, the supporting protrusions 152 and the second circuit board 170 form a heat dissipation space 180, in which case, the air flow in the heat dissipation space 180 helps to take away the heat generated by the first and

second circuit boards

160 and 170 and the first and second

light emitters

120 and 140.

In a further aspect, at least one of a heat sink 181 and a driver 182 may be disposed in the heat dissipation space 180. In the case where the heat sink 181 is disposed in the heat dissipation space 180, the heat dissipation performance of the projection lamp head apparatus 100 is further improved. In the case that the driver 182 is disposed in the heat dissipation space 180, the driver 182 is connected to the second circuit board 170, and the driver 182 can drive the second light emitter 140 to start.

In another alternative, the supporting frame 150 may be an integral structure with the first casing 110, in which case the supporting frame 150 can also play a role in reinforcing the strength of the first casing 110. Further, the supporting frame 150 and the first housing 110 may be made of metal, which undoubtedly can further improve the heat dissipation performance of the projection lamp head device 100.

As described above, the first light emitter 120 and the second light emitter 140 generate a large amount of heat during operation, and based on this, in an alternative scheme, a heat sink 181 is disposed between the first light emitter 120 and the second light emitter 140, and the heat sink 181 can effectively dissipate the heat generated by the first light emitter 120 and the second light emitter 140. Of course, in this case, the heat sink 181 does not have to be disposed in the heat dissipation space 180.

As described above, the first light emitter 120 is disposed on the first circuit board 160, and the second light emitter 140 is disposed on the second circuit board 170, so that the first light emitter 120 and the second light emitter 140 are respectively disposed with circuit boards, thereby avoiding thermal interference therebetween. Certainly, the first light emitter 120 and the second light emitter 140 may also share a circuit board, and based on this, in an optional scheme, the projection lamp head device 100 disclosed in the embodiment of the present invention may further include a third circuit board 190, the first light emitter 120 is disposed on a first board surface 191 of the third circuit board 190 facing the first direction, and the second light emitter 140 is disposed on a second board surface 192 of the third circuit board 190 facing the second direction, at this time, in a manner that the first light emitter 120 and the second light emitter 140 share the third circuit board 190, the number of circuit boards may be reduced, the cost of the projection lamp head device 100 may be reduced, and meanwhile, the structure of the projection lamp head device 100 may also be made more compact.

One or more second light emitters 140 may be provided, and in order to ensure the illumination brightness and the illumination uniformity of the projection lamp head device 100, the second light emitters 140 may be distributed in a predetermined manner, so that the second light emitters 140 can emit light uniformly. Specifically, the plurality of second light emitters 140 may be distributed in a row-column manner or in a ring-shaped manner.

Similarly, there may be one or more first light emitters 120. Considering that the projection mainly plays a decorative role, the first light emitter 120 may be one and may be disposed on the central axis of the first light outlet 110a, and at this time, the first light emitted by the first light emitter 120 may be emitted to the projection area through the first light outlet 110a without the need of too many first light emitters 120.

In addition, the projection lamp head device 100 may further include a first optical cover 1100, and the first optical cover 1100 is fixed to the second light outlet 110b, in which case, the second light emitted by the second light emitter 140 may be projected to the first optical cover 1100 through the first inner cavity 110c, and then emitted out of the projection lamp head device 100 through the first optical cover 1100. First optical mask 1100 can function as a light distribution. Specifically, the first optical mask 1100 may be a light-uniformizing mask, so that uniformity of illumination may be ensured. Meanwhile, the first optical mask 1100 may be disposed at the second light outlet 110b, and may play a role of blocking the second light outlet 110b, so as to prevent dust in the air from interfering with internal components of the projection lamp head device 100.

In a further embodiment, the first optical mask 1100 may include a first buckle 1110, the first buckle 1110 is buckled to the second light outlet 110b, and the first optical mask 1100 and the second light outlet 110b are assembled and buckled. Through first buckle 1110 for the assembly structure of first optical mask 1100 is comparatively simple, also makes things convenient for the user to carry out dismouting maintenance operation simultaneously.

In an embodiment of the invention, the projection lamp head device 100 may further include a projection lens assembly 1200, the projection lens assembly 1200 may include a first lens 1210, and the first light projected by the first light emitter 120 may be projected out of the first housing 110 through the first lens 1210. The first lens 1210 can be a collimating lens, and the collimating lens can be disposed on the first housing 110 and disposed opposite to the first light emitter 120, in this case, the first light projected by the first light emitter 120 can be changed into a parallel beam of collimated light and emitted from the first light outlet 110a through the collimating lens, so that the first light can be prevented from being too dispersed, and the formation of more significant light spots is facilitated.

Of course, in a further embodiment, the projection lens assembly 1200 may further include a second lens 1220, the first lens 1210 and the second lens 1220 are sequentially disposed in the first light projecting direction of the first light emitter 120, and the first light projected by the first light emitter 120 sequentially passes through the first lens 1210 and the second lens 1220 and is projected to the light adjusting component 130. The second lens 1220 may be a convex lens, and the first light rays may be converged into a light spot through the convex lens. Through the mode, the first light can be further converged through the convex lens, so that the light spot formed by the first light through the dimming component 130 is stronger in brightness, and the light spot formed in the projection area is clearer in shape.

In addition, the projection lamp head device 100 may further include a compression sleeve 1300, the compression sleeve 1300 is sleeved on the first housing 110, and the assembly manner is adopted, so that the assembly performance of the compression sleeve 1300 and the assembly manner is better, and the structure is more stable. The compression sleeve 1300 includes a flange 1310, and the dimming component 130 is clamped between the flange 1310 and the surface where the first light outlet 110a is located, in this case, the position of the dimming component 130 can be effectively fixed, and the dimming component 130 can be fixed without an excessively complicated fixing structure.

The lighting head device 200 and the projection head device 100 may be disposed at an interval, so that the coverage of light rays emitted by the lighting head device 200 and the projection head device 100 is wide, and in addition, the number of the lighting head devices 200 may be multiple, so that the range that can be illuminated is wide. The light projection direction of the lighting head device 200 may be opposite to the direction of the first light projection, and in this case, both functionality and decoration of the lighting fixture may be considered, so that the performance of the lighting fixture is better, and at the same time, the optical influence between the lighting head device 200 and the projection head device 100 may be alleviated.

In a further embodiment, the lighting head apparatus 200 may include a second housing 210, a second optical cover 220, and a light emitting module 230, where the second housing 210 may provide a mounting base for other components in the lighting head apparatus 200, and the second housing 210 is connected to the second optical cover 220 to form a mounting space.

Specifically, the light emitting module 230 may be disposed in a second inner cavity formed by the second housing 210 and the second optical mask 220, and the second optical mask 220 may distribute light of the second light emitted by the light emitting module 230, so as to meet a preset optical requirement. Meanwhile, the second optical mask 220 can prevent dust in the air from affecting the illumination brightness of the illumination head device 200, and provide a layer of protection for the light emitting module 230. In addition, in order to make the assembling performance of the lighting head device 200 better and the structure more stable, the light emitting module 230 may be fixedly engaged with the second housing 210, or the second optical mask 220 may be fixedly engaged with the second housing 210, or of course, the light emitting module 230 may be fixedly engaged with the second housing 210, and the second housing 210 is fixedly engaged with the second optical mask 220, which is not limited in this embodiment of the present invention.

In the embodiment of the present invention, the lighting fixture may further include a lamp holder 400 and a top box assembly 300, wherein the lamp holder 400 is used for fixedly connecting the projection lamp head device 100, the lighting lamp head device 200 and the top box assembly 300.
