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 specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The technical scheme disclosed by each embodiment of the invention is described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 4, an embodiment of the invention discloses a lighting fixture, which includes a housing 100, a first light source module 200, a light guide plate 300 and a second light source module 400.

The housing 100 is a base member of the lighting fixture, and the housing 100 provides a mounting base for other components of the lighting fixture. The housing 100 may be made of a polymer material, which has a smaller density, thereby being beneficial to reducing the weight of the lighting device. Of course, in view of heat dissipation performance, the case 100 may be made of a metal material having good heat dissipation performance, such as aluminum. The embodiment of the present invention is not limited to the specific material of the housing 100.

The case 100 has an inner cavity 110 and a mounting hole 120, the mounting hole 120 communicates the inner cavity 110 with the external environment of the case 100, the light guide plate 300 plays a role of light guide, and the light guide plate 300 is mounted in the mounting hole 120. Since the mounting hole 120 communicates with the external environment of the housing 100, the surface of the light guide plate 300 facing the outside of the housing 100 can serve as a part of the exterior surface of the lighting fixture after the light guide plate 300 is mounted in the mounting hole 120.

The first light source module 200 and the second light source module 400 are mounted on the housing 100, the first light source module 200 projects a first light ray a, and the second light source module 400 projects a second light ray B. The first light source module 200 projects the first light a, and is configured such that the first light a is projected outside the housing 100 through the light guide plate 300. The second light B projected from the second light source module 400 to the light guide plate 300 can be projected out of the housing 100 through the light guide plate 300, that is, the first light a and the second light B can be projected out of the housing 100 after being transmitted through the light guide plate 300.

In the embodiment of the invention, the housing 100 is a non-transparent housing, so that the interference of the ambient light outside the housing 100 through the housing 100 can be avoided. Specifically, after the casing 100 is made of a light-transmitting material, a layer of light-shielding coating is coated on the inner side surface of the casing 100, so as to realize the non-light-transmitting characteristic of the casing 100. Of course, the housing 100 may also be directly made of a non-light-transmitting material. Embodiments of the present invention are not limited to implementations of the non-light transmissive properties of the housing 100.

In the lighting fixture disclosed in the embodiment of the invention, the first light source module 200 and the second light source module 400 respectively emit the first light ray a and the second light ray B, and the first light ray a and the second light ray B can be projected outside the housing 100 after being guided by the light guide plate 300, so that the lighting fixture can emit the first light ray a and the second light ray B simultaneously.

The light guide plate 300 may have various structures, and in general, the light guide plate 300 includes a plurality of surfaces, and the first light a emitted from the first light source module 200 and the second light B emitted from the second light source module 400 may be incident on the same surface of the light guide plate 300 and then emitted out of the housing 100 from the other surface of the light guide plate 300. In order to better reflect the light effect difference between the first light ray a and the second light ray B, in a more preferred scheme, the first light source module 200 and the second light source module 400 respectively project the first light ray a and the second light ray B onto different light incident surfaces of the light guide plate 300, and the first light ray a and the second light ray B are emitted to the outside of the housing 100 through the same light emitting surface of the light guide plate 300. The light incident surface and the light emitting surface are different surfaces of the light guide plate 300.

Referring to fig. 1 again, the light guide plate 300 may include a first plate surface 310, a second plate surface 320 and a side surface 330, wherein the first plate surface 310 faces the inner cavity 110, the second plate surface 320 faces the outside of the housing 100, and the side surface 330 connects the first plate surface 310 and the second plate surface 320. The first light source module 200 projects the first light a to the first plate surface 310, and the second light source module 400 projects the second light B to the side surface 330, that is, the first plate surface 310 and the side surface 330 are different light incident surfaces of the light guide plate 300. The first light ray a and the second light ray B are emitted from the second plate 320 to the outside of the housing 100, and the second plate 320 is the light emitting surface of the light guide plate 300. In this case, the second light B is emitted from the side 330 into the light guide plate 300 and then emitted from the light guide plate 300, so that a brighter environment is advantageously formed, and the first light a is emitted from the first plate 310 and then emitted from the second plate 320, so that a differentiated illumination effect is easily formed, and a better illumination effect is realized.

In order to improve the projection effect, the second light source module 400 is disposed at one side of the side 330 so as to be more easily injected into the light guide plate 300 from the side 330. In a preferred embodiment, the second light source modules 400 may be symmetrically disposed on both sides of the light guide plate 300, and of course, the second light source modules 400 may also be disposed around the side surface 330. The second light source module 400 can be arranged in a manner that the second light source module can be incident into the side surface 330 from multiple directions, so that better projection of the second light B is realized.

Referring again to fig. 1-4, in embodiments of the present invention, the housing 100 may have a variety of structures. In a specific embodiment, the housing 100 may include a bottom wall 130, a top wall 140, and a side wall 150, the side wall 150 being a generally cylindrical structure, the side wall 150 being connected between the bottom wall 130 and the top wall 140, the bottom wall 130, the top wall 140, and the side wall 150 enclosing the interior cavity 110 of the housing 100.

Specifically, the mounting hole 120 may be formed on the bottom wall 130, and of course, the mounting hole 120 may be formed by abutting the side wall 150 with the bottom wall 130. The installation position of the installation hole 120 can enable the lighting lamp to project light in a downward direction. The embodiment of the present invention does not limit the specific formation and arrangement positions of the mounting holes 120.

Referring to fig. 1 to 3, one end of the bottom wall 130 may be provided with a notch, the notch and the side wall 150 may enclose an installation hole 120, and the first light source module 200 may be obliquely disposed between the other end of the bottom wall 130 and the top wall 140, where it should be noted that an included angle is formed between a light projection direction of the first light source module 200 and the side wall 150. Specifically, the first light source module 200 projects the first light a directly onto the light guide plate 300 in an inclined manner, or the first light a may be indirectly projected onto the light guide plate 300 after being reflected.

Specifically, the inner wall of the mounting hole 120 may have a mounting groove 160, and the edge of the light guide plate 300 may be inserted into the mounting groove 160, so as to realize the detachable mounting of the light guide plate 300 in the mounting hole 120, and the assembly manner is easier to realize the dismounting of the light guide plate 300, which is beneficial to the replacement of the light guide plate 300.

Referring to fig. 3 again, two parallel sheet structural members 151 may be disposed on the inner side surface of the side wall 150, the two sheet structural members 151 and the inner side surface of the side wall 150 form a first sub-groove, the inner wall of the opening may be provided with a second sub-groove, and the first sub-groove and the second sub-groove are abutted to form a mounting groove 160 surrounding the light guide plate 300. In the case where the mounting hole 120 is entirely opened on the bottom wall 130, the mounting groove 160 may be opened in the inner wall of the mounting hole 120.

As described above, the second light source module 400 is disposed at one side of the side surface 330, and the second light source module 400 is disposed between the side surface 330 and the bottom surface of the mounting groove 160 on the premise of having the mounting groove 160, so that the mounting of the second light source module 400 can be achieved by fully using the mounting groove 160 for mounting the light guide plate 300, and more compact assembly can be finally achieved.

The second light source module 400 may have various structures, in a specific embodiment, the second light source module 400 may include a circuit board 410 attached to the bottom surface of the mounting groove 160 and at least two light emitters 420 mounted on the circuit board 410 and projecting the second light B toward the side surface 330, and the light emitters 420 may be distributed along the side surface 330. The second light source module 400 having the above-described structure can certainly be mounted in the mounting groove 160, and can more easily project the second light B to the side surface 330 in multiple directions.

The circuit board 410 may be a rigid circuit board or a flexible circuit board. The illuminant 420 is preferably an LED illuminant, which has advantages of less heat generation, longer lifetime, and the like.

In the lighting fixture disclosed in the embodiment of the invention, the mounting hole 120 may occupy a certain space of the bottom wall 130. Specifically, the ratio of the area of the mounting hole 120 to the area of the bottom wall 130 may be 1:1.5-1:3. Of course, embodiments of the present invention are not limited to a particular size of mounting hole 120.

As described above, the first light source module 200 is disposed in the inner cavity 110 and directly projects the first light a to the light guide plate 300, and of course, the first light a emitted by the first light source module 200 may be reflected and projected onto the light guide plate 300. Based on this, in a preferred embodiment, at least a partial region of the inner side surface of the top wall 140 may be a reflective surface. The reflecting surface receives the first light a projected by the first light source module 200 and reflects the first light a onto the light guide plate 300. Specifically, the inner surface of the top wall 140 is a reflective surface, so that the first light source module 200 can flexibly adjust the projection angle, and meanwhile, the situation that the inner surface of the top wall 140 is a reflective surface and the other parts are not visual differences caused by the reflective surface can be avoided.

Of course, the inner surface of the top wall 140 may be provided with a reflective film or a reflective plate, and at least a portion of the surface of the reflective film or the reflective plate facing the bottom wall 130 is a reflective surface, and the reflective surface receives the first light a projected by the first light source module 200 and reflects the first light a onto the light guide plate 300.

In order to improve the light efficiency of the first light ray a, the reflectivity of the reflective surface may be more than 85%, for example, the reflectivity of the reflective surface may be more than 85% and less than 95%.

In order to achieve better light efficiency, in the lighting lamp disclosed by the embodiment of the invention, the colors of the first light A and the second light B are different, and on the premise of different colors, the first light A and the second light B are matched, so that a better illumination effect can be formed.

In a more preferred embodiment, the first light a may be white light, the second light B may be blue light, and the second light B is emitted after being projected onto the light guide plate 300, where the blue light is conducted in the light guide plate 300, so that a blue background environment can be formed, and the white light is emitted into the light guide plate 300 and projected out of the light guide plate 300, in this case, the effect similar to the effect of sunlight irradiation under a blue sky can be better simulated.

Of course, the first light ray a and the second light ray B may be different in at least one aspect of the projection direction, the color temperature and the brightness, and of course, the above parameters of the first light ray a and the second light ray B may be the same, and other parameters may be different, so long as the first light ray a and the second light ray B are capable of being mutually background, so that the user may feel the difference of light projection.

In order to make the light projection of the first light a and the second light B more uniform, the light guide plate 300 may be a nano light guide plate in a more preferable scheme. The nanometer light guide plate comprises nanometer particles which are distributed in a discrete mode, and the nanometer particles can better disperse the first light A and the second light B, so that a good light homogenizing effect is achieved.

Referring to fig. 4 again, in a specific embodiment, the first light source module 200 may include a substrate 210, a circuit board 220, a light distribution element 230, and at least two light emitters 240 distributed in an array.

After the light distribution of the at least two light emitters 240 by the light distribution element 230, the first light ray a can be projected. Specifically, the at least two light emitters 240 distributed in an array more easily make the first light a be a group of light rays close to each other in parallel, thereby being beneficial to improving the light efficiency of the first light a.

In a preferred embodiment, the substrate 210 may be a base with good heat dissipation performance, for example, a metal base, so that heat dissipation in the working process of the first light source module 200 can be better achieved.

In order to improve the projection effect of the first light a, the first light source module 200 may further include a diffusion device 250 covering the illuminant 240, and the diffusion device 250 may enable the first light a to be more dispersed, thereby improving the uniformity of illumination. In particular, the diffusion device 250 may be a diffusion film, a diffusion plate, a frosting plate, etc., and embodiments of the present invention are not limited to a specific type of diffusion device 250.

The lighting fixture disclosed in the embodiment of the invention may further include a mounting bracket 500, and the first light source module 200 may be mounted in the inner cavity 110 through the mounting bracket 500. Specifically, the first light source module 200 may be supported on the side wall 150 by the mounting bracket 500, or may be supported on the bottom wall 130 by the mounting bracket 500.

In a more preferred embodiment, one end of the mounting bracket 500 is fixed in the inner cavity 110, and the first light source module 200 is hinged to the other end of the mounting bracket 500, so that the first light source module can rotate relative to the mounting bracket 500, and thus the light projection angle can be flexibly adjusted.

The foregoing embodiments of the present invention mainly describe differences between the embodiments, and as long as there is no contradiction between different optimization features of the embodiments, the embodiments may be combined to form a better embodiment, and in view of brevity of line text, no further description is provided herein.
