The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0058] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0059] In this application, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit this application.

[0060] In order to solve the problem that the existing lamps have a single light emitting direction and cannot be adjusted according to the user's own application scenario needs, the present application provides a lamp. The lamp can be a chandelier, a long strip lamp, etc.

[0061] Example 1

[0062] As shown in Figures 1 to 4, the lamp includes a lamp body 10 and a light source 20. The lamp body 10 has a reflective structure, and the reflective structure has a reflective cavity 103. A top light outlet 101 and a bottom light outlet 102 are respectively formed at both ends of the reflective cavity 103. The light source 20 is arranged inside the reflective cavity 103 and is spaced apart from the inner wall of the reflective structure. At least a portion of the light from the light source 20 is emitted toward the inner wall surface of the reflective structure. The inner wall surface of the reflective structure is used to reflect the light so that the light is emitted from the top light outlet 101 and the bottom light outlet 102. The light source 20 is movably arranged to adjust the luminous flux of the top light outlet 101 and the bottom light outlet 102.

[0063] Specifically, the reflective structure of the lamp of the present application forms a dual light outlet structure setting of a top light outlet 101 and a bottom light outlet 102, which increases the light outlet direction; at the same time, the light source 20 of the present application is movably set to adjust the light outlet path of the light by adjusting the light source 20 and the reflective structure, thereby adjusting the luminous flux of the top light outlet 101 and the bottom light outlet 102, and can adjust the light output according to the needs of the usage scenario, thereby improving the user experience.

[0064] Furthermore, the light source 20 is rotatably arranged inside the reflective cavity 103, and the light-emitting direction of the light source 20 is adjusted by rotation. The light emitted by the light source 20 is directed toward the inner wall surface of the reflective structure, so that the light is guided to the top light outlet 101 and the bottom light outlet 102 under the reflection action of the inner wall surface of the reflective structure, thereby changing the luminous flux of the top light outlet 101 and the bottom light outlet 102.

[0065] In this embodiment, the reflective structure includes two reflective plates 110 disposed opposite each other, forming a reflective cavity 103 between the two reflective plates 110. The surfaces of the two reflective plates 110 facing each other serve as reflective surfaces. The light source 20 is rotatably disposed between the two reflective plates 110 and emits light toward the reflective surfaces. The reflective surfaces are used to reflect light and direct it toward the top light outlet 101 and the bottom light outlet 102.

[0066] It should be noted that the lamp of the present application is installed at a location to be installed, such as a wall, ceiling or other structural member, and the position of the light source 20 is rotated and adjusted according to the need for light. In order to avoid the phenomenon that light directly shines on the bottom light outlet 102 and directly shines on the user or the light directly emitted from the bottom light outlet 102 is dazzling, the light emitting direction of the light source 20 of the present application is set at an angle to the opening direction of the bottom light outlet 102. Among them, non-direct means that the light emitting direction of the light source 20 and the opening direction of the bottom light outlet 102 form an angle of 90° to 270°, but not including the situation of 90° and 270°.

[0067] Of course, if light needs to be provided, the light source 20 can also be configured to be rotatable 360°.

[0068] To further explain the above description, indirect emission in this application means that the light emitted by the light source 20 is reflected by any reflective member in the reflective cavity 103 and then emitted from the top light outlet 101 and the bottom light outlet 102. Of course, in actual applications, it is not limited to the method of using reflection for all light. It is also possible that part of the light emitted by the light source 20 is directly emitted from the top light outlet 101 and the bottom light outlet 102 without being reflected, that is, part of the light is directly emitted.

[0069] It is further explained that the light emitted from the top light outlet 101 can be direct, and when the direct light hits the ceiling or the wall, it will reflect the light to achieve the lighting effect.

[0070] As shown in FIG. 1 to FIG. 4 , along the direction of the top light outlet 101 and the bottom light outlet 102 , the distance between the light source 20 and the top light outlet 101 is greater than the distance between the light source 20 and the bottom light outlet 102 .

[0071] Specifically, the light source 20 is arranged at a position close to the bottom light outlet 102, and the light source 20 can be rotatably arranged to adjust the light-emitting direction of the light source 20, wherein the main light-emitting direction of the light source 20 is directly or reflected from the top light outlet 101, and part of the light is emitted through the bottom light outlet 102 under the action of reflection. The means of rotating the light source 20 is used to adjust the luminous flux of the top light outlet 101 and the bottom light outlet 102, and also to adjust the main light emitted from the top light outlet 101 and the main light emitted from the bottom light outlet 102.

[0072] Furthermore, the distance between the light source 20 and the top light outlet 101 is not limited to being greater than the distance between the light source 20 and the bottom light outlet 102. Alternatively, the distance between the light source 20 and the top light outlet 101 may be less than the distance between the light source 20 and the bottom light outlet 102. In this case, the main light emission direction of the light source 20 is still emitted from the top light outlet 101.

[0073] In this embodiment, since the light source 20 is rotatably arranged, when only one light source 20 is provided, the distances between the light source 20 and the two reflective plates 110 can be equal or unequal. By adjusting the light emission direction of the light source 20, the illumination areas of the top light outlet 101 and the bottom light outlet 102 can be adjusted.

[0074] Furthermore, by adjusting the light source 20, the illumination areas of the top light outlet 101 and the bottom light outlet 102 can be switched between symmetry and asymmetry. When the light source 20 is irradiating toward the reflective surface of a reflector 110, the illumination areas of the top light outlet 101 and the bottom light outlet 102 are asymmetric. That is, the light emitted from the top light outlet 101 and the bottom light outlet 102 is not uneven, and most of the light is deflected toward one of the reflectors 110. Specifically, the deflection direction can be adjusted by adjusting the height of the reflector 110 and the orientation of the light source 20.

[0075] In this embodiment, since the light source 20 is rotatably arranged, when there are multiple light sources 20 and they are respectively arranged corresponding to different reflective plates 110, a heat dissipation gap 1031 is formed between the light source 20 and its adjacent reflective plates 110 to improve the heat dissipation efficiency of the light source 20.

[0076] The multiple light sources 20 are arranged at the same height to facilitate adjustment of the luminous flux of the top light outlet 101 and the bottom light outlet 102. Of course, the multiple light sources 20 may not be arranged at the same height.

[0077] As shown in FIG1 to FIG4, the lamp body 10 further includes oppositely arranged end covers 120, the reflector 110 is fixedly mounted on the end covers 120, the reflector 110 and the end covers 120 cooperate to form a reflective cavity 103, and the end covers 120 are used to connect to the location to be installed.

[0078] The light source 20 is rotatably disposed on the end cover 120 , so that the light source 20 can be rotated and adjusted between the two reflective plates 110 .

[0079] Specifically, the fixed end cap 120 and the reflective plate 110 form a reflective cavity 103 . The reflective plate 110 is used to reflect light, and the end cap 120 is used to block light and provide an installation position for the reflective plate 110 .

[0080] Furthermore, the two reflective plates 110 may be arranged in parallel, or may be arranged in a trumpet-shaped structure, so that one of the top light outlet 101 and the bottom light outlet 102 is larger than the other.

[0081] Furthermore, the reflective plate 110 is arranged perpendicular to the installation position so that the light output direction of the top light outlet 101 is toward the installation position, so as to reflect light through the installation position to improve the lighting effect; the bottom light outlet 102 is facing away from the installation position.

[0082] Furthermore, the reflective plate 110 and the end cover 120 are arranged vertically to improve the installation stability of the reflective plate 110 and the end cover 120 .

[0083] In this embodiment, the end cap 120 can be connected to the location to be installed by a flexible connector such as a suspension rope 50 or a chain, or by a hard connector such as a connecting column or a connecting rod, or by an adsorption connection through a suction cup.

[0084] As shown in FIG. 1 to FIG. 4 , the light source 20 is rotatably connected to the end cover 120 of the lamp body 10 through a set of transmission components 40 .

[0085] Specifically, the transmission assembly 40 includes at least one set of movable parts, which are rotatably connected to the end cover 120 . The light source 20 is mounted on the movable parts, and the light source 20 is rotatably connected to the end cover 120 via the movable parts.

[0086] Each group of movable parts has two movable parts arranged in pairs, and the two movable parts are movably connected to the two end caps 120. Alternatively, a group of movable parts can be an integral movable part, the light source 20 is mounted on the entire movable part, and the two ends of the entire movable part are movably connected to the two end caps 120.

[0087] It should be noted that the two movable parts arranged in a pair refer to two parts arranged on both sides of the light source 20 facing the two end covers 120 .

[0088] In this embodiment, the movable member is a movable shaft, and the light source 20 is rotatably connected to the end cover 120 via the movable shaft.

[0089] Furthermore, the end cap 120 has a mounting hole, the inner wall of which is provided with a plurality of groove structures. The outer circumference of the end of the movable member is provided with at least one protrusion, which engages with the groove structure. During the rotation of the movable member, the protrusion engages with different groove structures to enable the movable member to switch between different positions.

[0090] Of course, the method of realizing self-rotation is not limited to the above-mentioned structure of the protrusion and the groove structure engaging with each other. In this embodiment, a light source fixing shaft can also be provided on the end cover 120, and the light source fixing shaft can extend toward or away from the reflective cavity 103. The movable member rotates with the light source fixing shaft, thereby realizing the rotation of the light source 20 around the light source fixing shaft through the movable member, thereby realizing the rotation adjustment of the light source 20. Among them, one end of the movable member is connected to the light source 20, and the other end is bent and rotatably mounted on the light source fixing shaft.

[0091] In this embodiment, the rotation adjustment of the light source 20 can be manually adjusted or adjusted by a driver 410. Specifically, the transmission assembly 40 also includes a driver 410, which is mounted on the end cap 120 and is drivingly connected to the movable member. The driver 410 can be a driving structure such as a motor or a cylinder.

[0092] Furthermore, the mutually facing surfaces of the reflective plates 110 serve as reflective surfaces, which can be either straight or curved. When the reflective surface is a straight surface, along the direction of the top light outlet 101 and the bottom light outlet 102, the reflective surface can be a single, flat surface, or can be formed by sequentially connecting multiple angled flat surfaces. When the reflective surface is a curved surface, to improve light reflection efficiency, light is reflected through a curved surface with a preset curvature. The curved surface can be the outer surface of a structure protruding from the reflective surface, or the inner surface of a groove structure provided on the reflective surface.

[0093] The reflector 110 of this embodiment is not limited to being made of opaque reflective materials. If necessary, the reflector 110 can also be made of translucent or transparent materials to achieve the goal of reflecting light while allowing some light to pass through the reflector 110 for side emission. For example, a prism structure that can achieve both reflection and refraction can be used.

[0094] Furthermore, in order to improve the reflection efficiency, the reflective surface may be covered with a reflective film, reflective paint or reflective powder.

[0095] In this embodiment, the light source 20 is a linear light source 20 , and the lamp as a whole is a long strip lamp structure.

[0096] In this embodiment, the end surfaces of the reflective plate 110 that are away from each other can be a flat structure or a curved surface.

[0182] Specifically, indirect emission in this application means that the light emitted by the light source 20 is reflected by any reflective member in the reflective cavity 103 and then emitted from the top light outlet 101 and the bottom light outlet 102.

[0183] It is further explained that when the space below the bottom light outlet 102 is a non-human activity space, or does not have the function of a human activity space, the light from the light source 20 can be directly emitted from the bottom light outlet 102. When the directly emitted light shines on the ground or the wall, it will reflect the light to achieve lighting.

[0184] In this embodiment, the main light emission direction of the light outlet of the light source is toward a direction away from the top light outlet 101 .

[0185] From the above description, it can be seen that the above embodiments of the present application achieve the following technical effects:
