Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

The embodiment of the application provides a lamp. Referring to fig. 1, a luminaire 100 may include: a first light source 1301, a second light source 1302, a first reflector 110, a second reflector 120, and a light guide plate 140. The second reflector 120 is disposed at the outer circumference of the first reflector 110, an inner wall 1101 of the first reflector 110 forms a first reflective cavity 1103, and an outer wall 1102 of the first reflector 110 and an inner wall 1201 of the second reflector 120 form a second reflective cavity 1202. The first light source 1301 is disposed toward the first reflective cavity 1103 and the second light source 1302 is disposed toward the second reflective cavity 1202, the first light source 1301 and the second light source 1302 being oriented in the same direction. The light guide plate 140 is in a ring structure, the light guide plate 140 is sandwiched between an end of the second reflector 120 far from the second light source 1302 and the outer wall 1102 of the first reflector 110, the inner side 1401 of the light guide plate 140 extends into the second reflective cavity 1202, and the outer side 1402 of the light guide plate 140 extends out of the second reflective cavity 1202.

In this way, in the embodiment of the present application, the light emitted from the first light source 1301 can exit along the opening of the first reflective cavity 1103, and the light emitted from the second light source 1302 can enter the light guide plate 140 through the inner side 1401 of the annular light guide plate 140 and exit from the outer side of the light guide plate 140. Thus, the light emitted by the first light source 1301 can be emitted from the axial direction of the lamp, and the light emitted by the second light source 1302 can be emitted from the lateral direction of the lamp after passing through the annular light guide plate 140, so that the problem that the light emitted by the lamp in the related art is single can be solved. The light rays of the second light source 1302 transmitted laterally by the light guide plate 140 can illuminate the light guide plate 140, and the light rays emitted laterally by the light guide plate 140 cannot directly enter the eyes of the observer, so that the light guide plate 140 can have a glittering and translucent effect, and the optical effect of the lamp 100 can be improved.

Optionally, in the embodiment of the present application, a portion of the outer wall 1102 of the first reflector 110 away from the first light source 1301 extends toward the outer periphery in the radial direction. The projection of the end of the outer wall 1102 of the first reflector 110 far from the first light source 1301 in the irradiation direction of the second light source 1302 is located outside the projection of the end of the inner wall 1201 of the second reflector 120 far from the second light source 1302 in the irradiation direction of the second light source 1302. In this way, the inner wall 1201 of the second reflector 120 can reflect the light emitted from the second light source 1302 in the axial direction of the lamp, so that the light emitted from the second light source 1302 can be emitted in the lateral direction of the light guide plate 140 as much as possible. Moreover, the light emitted from the second light source 1302 along the axial direction of the lamp 100 can be shielded, so that an annular shielding ring is arranged between the light emitted from the first light source 1301 and the light emitted from the second light source 1302, the light emitted from the first light source 1301 and the light emitted from the second light source 1302 can be separated, and the optical effect of the lamp 100 can be improved.

Optionally, in the embodiment of the present application, an end of the first reflector 110 far from the first light source 1301 may be provided with an extension 1104, and the extension 1104 may be perpendicular to the axis of the luminaire 100, that is, the extension 1104 may be perpendicular to the irradiation direction of the first light source 1301. The light guide plate 140 may be disposed between the top end of the second reflector 120 and the extension portion 1104, wherein the light guide plate 140 may be perpendicular to the axis of the luminaire 100, that is, the light guide plate 140 may be perpendicular to the emitting direction of the first light source 1301. Alternatively, in other embodiments of the present application, the extension 1104 may be disposed obliquely, and the light guide plate 140 may also be disposed obliquely. That is, an included angle between the light guide plate 140 and the emitting direction of the first light source 1301 may be greater than 90 degrees or less than 90 degrees.

Optionally, in the embodiment of the present application, the inner side 1401 of the light guide plate 140 may be an obliquely disposed light incident surface, and the light incident surface may face the outer wall 1102 of the first reflector 110. Thus, the light emitted from the second light source 1302 is incident into the light guide plate 140 through the light incident surface and is emitted through the light guide plate 140. Alternatively, in an embodiment of the present application, the outer wall 1102 of the first reflecting body 110 may be a reflecting surface.

Optionally, in the embodiment of the present application, the light incident surface may be a light surface, so that the light emitted by the second light source 1302 is incident into the light guide plate 140 through the light incident surface and is emitted out through the light guide plate 140. Alternatively, the outer side 1402 of the light guide plate 140 may be a light emitting surface, and the light emitting surface may be a frosted surface. Thus, the light emitted by the second light source 1302 can irradiate the light emitting surface of the light guide plate 140, so as to form a hazy light effect on the light emitting surface of the light guide plate 140, thereby improving the appearance performance of the lamp 100. Optionally, in an embodiment of the application, the light guide plate 140 has a flat plate-shaped structure, and an included angle between the light incident surface and a plate surface of the light guide plate 140 is 45 degrees. Alternatively, the light exit surface may be obliquely disposed toward a direction away from the irradiation direction of the second light source 1302.

Alternatively, in the embodiment of the present application, the cross-sectional shape of the first reflecting body 110 along the direction perpendicular to the axis may be a circle, a polygon, an ellipse, or the like, and of course, the cross-sectional shape of the first reflecting body 110 along the direction perpendicular to the axis may also be other closed figures. The cross-sectional shape of the second reflector 120 along the direction perpendicular to the axis may be a circle, a polygon, an ellipse, etc., and of course, the cross-sectional shape of the second reflector 120 along the direction perpendicular to the axis may be other closed shapes. The inner side 1401 of the light guide plate 140 may have a circular shape, a polygonal shape, an oval shape, or the like, and the inner side 1401 of the light guide plate 140 may have other closed shapes. The outer side 1402 of the light guide plate 140 may have a circular, polygonal, or oval shape, but the outer side 1402 of the light guide plate 140 may have other closed shapes.

Alternatively, in an embodiment of the present application, the light emitted by the first light source 1301 and the second light source 1302 may be different, or the first light source 1301 and the second light source 1302 may be different types of light sources. In this way, the light emitted by the luminaire 100 and emitted by the first light source 1301 and the second light source 1302 may have a certain difference, so that the luminaire 100 may create a better light atmosphere.

Alternatively, the color temperature of the first light source 1301 and the second light source 1302 may be different. For example, the first light source 1301 may be a light source with a white color temperature, and the second light source 1302 may be a light source with a yellow color temperature, so that the middle region of the luminaire 100 may emit white light, which may have a better lighting effect, and the periphery of the middle region may emit yellow light, which is softer, and may improve the overall appearance of the luminaire 100. Of course, in other embodiments of the present application, the first light source 1301 may be a light source with a yellow color temperature, and the second light source 1302 may be a light source with a white color temperature, which are not listed here.

Optionally, the brightness of the first light source 1301 may be different from the brightness of the second light source 1302, for example, the brightness of the first light source 1301 may be greater than the brightness of the second light source 1302, so that the middle area of the lamp 100 is brighter, which may achieve a better lighting effect, and the periphery of the middle area is darker, which may improve the overall appearance of the lamp 100. Of course, in other embodiments of the present application, the brightness of the first light source 1301 may be less than the brightness of the second light source 1302, which is not listed here.

Alternatively, in other embodiments of the present application, the light emitted by the first light source 1301 and the second light source 1302 may be the same, or the first light source 1301 and the second light source 1302 may be the same type of light source. Further, it is possible to enable the luminaire 100 to emit two different lights by providing a means for changing the type of light on the light emitting path of the first light source 1301 and/or the second light source 1302. For example, a lens made of a frosted material may be disposed on the light outgoing path of the first light source 1301, and the type of light emitted from the first light source 1301 may be changed by using the lens made of the frosted material, which is not listed here.

Of course, in other embodiments of the present application, the light emitted by the first light source 1301 and the second light source 1302 may be the same, or the first light source 1301 and the second light source 1302 may be the same type of light source. Further, the type of light emitted through the reflective cavity can be varied by varying the configuration of the first reflective cavity 1103 and/or the second reflective cavity 1202. For example, the texture of the emitting surfaces of the first reflective cavity 1103 and the second reflective cavity 1202 may be different, for example, a silver reflective film may be plated on the first reflective cavity 1103, a gold reflective film may be plated on the surface of the second reflective cavity 1202, and the types of light rays emitted from the first reflective cavity 1103 and the second reflective cavity 1202 may also be different, which is not listed here.

In the embodiments of the present application, the orientations of the first light source 1301 and the second light source 1302 are the same, and do not mean that the irradiation directions of the first light source 1301 and the second light source 1302 must be completely the same. For example, the irradiation direction of the first light source 1301 may be directed to the front left, the irradiation direction of the second light source 1302 may be directed to the front right, and both may be directed to the front, and the irradiation direction of the first light source 1301 and the irradiation direction of the second light source 1302 may be considered to be the same. Alternatively, in an embodiment of the present application, the first light source 1301 and the second light source 1302 may both face the front.
