Description

TECHNICAL FIELD

[0001] The present application relates to the field of lighting, in particular to an indoor floor lamp for indirect lighting. BACKGROUND

[0002] Currently, the floor lamps on the market mainly adopt two common light emitting modes, but both have certain limitations: the direct down light emitting floor lamp adopts LED lamp beads directly downward irradiation, the light is concentrated, the brightness is high, and it is suitable for local lighting, such as reading lamp. The side light emitting floor lamp with light guide plate guides the light source to the lighting area laterally through the light guide plate to realize more uniform light distribution. It is suitable for office lighting and local atmosphere lighting.

[0003] The existing two light sources have the following problems: the traditional direct down light emitting light source is too concentrated, the light is not soft, the glare is strong, which leads to the over-brightness of the high-brightness area and the darkness of the surrounding area, affecting the visual comfort. Since the light source is directly exposed, the light is too dazzling, which easily forms obvious light spots, affecting the visual comfort. It is suitable for local lighting, such as reading lamp, but not suitable for large-area soft lighting. The light guide plate of the side light emitting floor lamp with light guide plate can improve the glare problem, but the light emitting angle is limited and not easy to adjust, it is difficult to uniformly cover a large area of space, the light loss is large, leading to light dead angle, which is not conducive to large-scale diffusion of light source. High manufacturing cost: the light guide plate needs precise optical design, the processing technology is complex, leading to high cost, which is not conducive to low-cost popularization.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] Please refer to Figures 1 to 8 This application provides an indoor floor lamp 1000 for indirect lighting, comprising a lamp body 100 having an upper light-emitting surface 11 and / or a lower light-emitting surface 12; characterized in that the indoor floor lamp 1000 further comprises: a groove 40, which, when viewed from a horizontal direction, includes a groove bottom, a groove opening opposite to the groove bottom, a first side surface 41a disposed between the groove opening and the groove bottom, and a second side surface 41b opposite to the first side surface 41a; a light-emitting body 50 disposed on the first side surface 41a or the second side surface 41b; and a reflector 20 disposed in the groove 40, wherein the light emitted by the light-emitting body 50, after being reflected by the reflector 20, indirectly illuminates the outside through the groove opening at least through one of the upper light-emitting surface 11 or the lower light-emitting surface 12.

[0045] In this embodiment, it should be noted that the lamp body 100 is typically made of aluminum alloy or high-strength engineering plastic, which ensures structural rigidity and facilitates heat dissipation. The lamp body 100 has internal space reserved to accommodate other optical components, including a groove 40, a light-emitting element 50, and a reflector 20. When viewed horizontally, the groove 40 includes a bottom, an opening opposite the bottom, a first side 41a located between the opening and the bottom, and a second side 41b opposite the first side 41a. The light-emitting element 50 is disposed on either the first side 41a or the second side 41b and emits light towards the inside of the groove 40. The groove 40 also contains a reflector 20, which reflects the light emitted from the light-emitting element 50, allowing the light to indirectly illuminate the outside through the opening at least via the upper light-emitting surface 11 or the lower light-emitting surface 12. This structural design prevents the light from directly illuminating the outside, instead diffusing it after reflection, thus providing a softer, indirect lighting effect.

[0046] The light-emitting element 50 is typically an LED light panel, composed of high-brightness, low-energy-consumption LED components. It is fitted and mounted on one side of the groove 40. This mounting method ensures a tight fit between the LED light panel and the reflector 20, guaranteeing that the emitted light can fully enter the light cavity for secondary reflection. The light-emitting element 50, as the light source, directly provides light energy; its output light is reflected by the reflector 20, forming indirect lighting.

[0047] The reflector 20 is designed so that one end is in close contact with the light-emitting element 50, and the other end extends along a preset shape. Its structure is as follows: One end of the reflector 20 is located at the connection between the light-emitting element 50 and the light-emitting surface of the groove 40, ensuring that the light is effectively captured after emission. Starting from the lower end, the reflector 20 extends along a preset shape to the other side of the groove 40, and its shape is carefully designed to change the reflection angle of the light. The other end of the reflector 20 abuts against the other side of the groove 40 at the connection with the light-emitting surface, achieving uniform light distribution through its arc-shaped structure.

[0048] The technical solution implemented in this embodiment has the following beneficial effects: By setting the LED light panel on one side of the groove 40 and using the reflector 20 to extend along an arc to reflect light to the entire lighting area, glare caused by direct light is avoided, achieving soft indirect lighting that is more eye-friendly for prolonged use. Highly efficient indirect lighting is achieved using a simple reflector 20 structure, eliminating the need for costly light guide plates or complex optical components, thereby reducing production costs while maintaining excellent optical performance. The arc-shaped extension design of the reflector 20 allows for controllable light reflection angles, and through reasonable design, light distribution can be further optimized to meet the needs of different lighting scenarios.

[0049] In another embodiment, the reflector 20 has a reflective surface on the side near the upper light-emitting surface 11 or the lower light-emitting surface 12, and the light-emitting body 50 is located between the reflector 20 and the upper light-emitting surface 11 or the lower light-emitting surface 12. The light emitted by the light-emitting body 50 is reflected by the reflective surface and then emitted through the upper light-emitting surface 11 or the lower light-emitting surface 12.

[0050] The reflector 20 includes: a fixing part 21, disposed on one of the first side surface 41a or the second side surface 41b, wherein the first side surface 41a or the second side surface 41b is provided with a light-emitting element 50; and a reflecting part, one end of which is connected to the fixing part 21, and the other end of which abuts against the other of the first side surface 41a or the second side surface 41b. Optionally, the reflecting part includes: a first reflecting part 22 and a second reflecting part 23. When viewed in the horizontal direction, the first reflecting part 22 is perpendicular to the first side surface 41a, one end of which abuts against the fixing part 21, and the other end of which abuts against the second reflecting part 23; the cross-section of the second reflecting part 23 is arc-shaped, or is a straight line forming an angle of less than 180° with the first reflecting part 22, or is fitted into the groove 40.

[0051] In this embodiment, it should be noted that the reflective part of the reflector 20 is used to adjust the direction of light so that the light is reflected and emitted from the light-emitting surface.

[0052] By implementing the technical solution of this embodiment, the reflection angle of light can be optimized, so that the light can be diffused more evenly into the room through the upper light-emitting surface 11 or the lower light-emitting surface 12, and a softer and more uniform indirect lighting effect can be formed. Traditional direct light sources are prone to producing strong light spots or glare, while this design uses reflectors 20 to guide and diffuse the light, making the light softer and reducing the discomfort of direct light to the human eye.

[0053] In an optional embodiment, the first side 41a or the second side 41b, which has the fixing part 21, is provided with a protrusion that extends horizontally, and the fixing part 21 is disposed between the protrusion and the bottom of the groove. In this embodiment, because the first side 41a or the second side 41b has a protrusion that extends horizontally, and the fixing part 21 is provided between it and the bottom of the groove, the installation of the reflector 20 is more stable. This design not only ensures the reliable fixing of the reflector 20, but also effectively reduces displacement caused by vibration or external force, improving the product's service life and light stability. At the same time, the presence of the protrusion provides additional support, making the fixing of the reflector 20 more stable and avoiding deformation or loosening problems that may occur during long-term use.

[0054] In one specific embodiment, the groove 40 includes a first groove 40a and a second groove 40b. The light-emitting body 50 includes a first light-emitting body 51 disposed in the first groove 40a and a second light-emitting body 52 disposed in the second groove 40b. Viewed horizontally, the first groove 40a is on the left and the second groove 40b is on the right. The first groove 40a includes a third side 41c facing away from the second groove 40b and a fourth side 41d opposite to the third side 41c. The second groove 40b includes a fifth side 41e adjacent to the first groove 40a and a sixth side 41f opposite to the fifth side 41e. The first light-emitting body 51 is disposed on the fourth side 41d of the first groove 40a, and the second light-emitting body 52 is symmetrically disposed on the fifth side 41e of the second groove 40b. Alternatively, the first light-emitting body 51 is disposed on the third side 41c of the first groove 40a, and the second light-emitting body 52 is symmetrically disposed on the sixth side 41f of the second groove 40b.

[0055] In this embodiment, the groove 40 is divided into a first groove 40a and a second groove 40b, and a first light-emitting element 51 and a second light-emitting element 52 are respectively disposed thereon. Its structural features are as follows: a double-groove structure, with the first groove 40a located on the left side, including a third side 41c facing away from the second groove 40b and a fourth side 41d opposite to it. The second groove 40b is located on the right side, including a fifth side 41e adjacent to the first groove 40a and a sixth side 41f opposite to the fifth side 41e. This design allows for a symmetrically distributed light source layout inside the lamp, optimizing the light propagation path and improving illumination uniformity. The light-emitting elements 50 are symmetrically arranged in two ways: First, the first light-emitting element 51 is disposed on the fourth side 41d of the first groove 40a (closer to the second groove 40b). The second light-emitting element 52 is symmetrically disposed on the fifth side 41e of the second groove 40b (also close to the first groove 40a). Second, the first light-emitting element 51 is disposed on the third side 41c of the first groove 40a (facing away from the second groove 40b). The second light-emitting element 52 is symmetrically arranged on the sixth side 41f of the second groove 40b (the side facing away from the first groove 40a). By using different installation methods, the reflection and dispersion direction of light can be changed to adapt to different lighting needs.

[0056] Implementing the technical solution of this embodiment, since the first light-emitting body 51 and the second light-emitting body 52 are arranged symmetrically, the light emitted from the grooves 40 on both sides can be more evenly distributed on the upper light-emitting surface 11 or the lower light-emitting surface 12 after reflection. Traditional single-sided light-emitting design may lead to uneven light distribution, while this double-groove 40 + symmetrical light source layout can effectively eliminate lighting dead angles and make the light more natural and soft. Since the light sources are respectively arranged in the first groove 40a and the second groove 40b, and the light is reflected before being emitted, the shadow problem caused by unidirectional light emission can be avoided, making the brightness of the entire lighting area more uniform. This structure is particularly suitable for indirect lighting applications, such as living rooms, bedrooms, and office areas, and can create a more comfortable lighting environment. If the light-emitting body 50 is set on the side closer to the adjacent groove 40 (the fourth side 41d and the fifth side 41e), the light can be concentrated towards the center, which is suitable for scenarios that require higher brightness or stronger beam guidance. If the light-emitting body 50 is set on the side farther from the adjacent groove 40 (the third side 41c and the sixth side 41f), the light can be diffused outward, which is suitable for more uniform and softer lighting needs. This allows the floor lamp 1000 to adapt to different lighting needs through different light emission methods, such as local lighting, ambient lighting, and focused area lighting. At the same time, the structure of the first groove 40a and the second groove 40b enhances the rigidity of the overall lamp body 100. Compared with a single groove 40 design, this double groove 40 structure can better distribute external pressure, reduce the possibility of lamp body 100 deformation, and improve the durability of the lamp.

[0057] In an optional embodiment, the groove 40 further includes a third groove 40c, and the light-emitting body 50 further includes a third light-emitting body 53; the third groove 40c is located between the first groove 40a and the second groove 40b, and the third light-emitting body 53 is disposed in the third groove 40c and located at the bottom of the third groove 40c.

[0058] In this embodiment, it should be noted that, compared to the previous dual-groove 40 design (first groove 40a + second groove 40b), a third groove 40c and a third light-emitting element 53 are added, forming a three-groove 40 structure. The specific layout is as follows: the third groove 40c is located between the first groove 40a and the second groove 40b, that is, in the central position of the entire structure. This design adds a central light source to the light distribution. The third light-emitting element 53 is located at the bottom of the third groove 40c, meaning that this light source emits light upwards or outwards. Compared to the first light-emitting element 51 and the second light-emitting element 52 (usually mounted on the sidewalls of the groove 40), the position of the third light-emitting element 53 allows its light to diffuse directly upwards or to both sides, further improving the overall lighting effect.

[0059] In implementing the technical solution of this embodiment, the first light source 51 and the second light source 52 are mainly distributed in the grooves 40 on the left and right sides. If there are only these two light sources, uneven lighting may occur in the central area. The addition of the third light source 53 allows the light source to provide additional brightness compensation in the central area, making up for the possible brightness difference between the light sources on the left and right sides, and making the light more uniform.

[0060] In another optional embodiment, when the indoor floor lamp 1000 includes an upper luminous surface 11 and a lower luminous surface 12, the groove 40 further includes a fourth groove 40d, and the light-emitting body 50 further includes a fourth light-emitting body 54; the first groove 40a and the second groove 40b are disposed in one of the upper luminous surface 11 and the lower luminous surface 12, the fourth groove 40d is disposed in the other of the upper luminous surface 11 and the lower luminous surface 12, and the fourth light-emitting body 54 is disposed inside the fourth groove 40d and located at the bottom of the fourth groove 40d.

[0061] Specifically, there are two configuration methods: first groove 40a + second groove 40b + fourth groove 40d; first groove 40a + second groove 40b + third groove 40c + fourth groove 40d.

[0062] The technical solution of this embodiment provides a double-sided light-emitting indoor floor lamp 1000 structure by adding a fourth groove 40d and a fourth light-emitting body 54. It emits light upwards and downwards at the same time to create a soft ambient light, while meeting functional lighting needs and realizing light diffusion in different directions, making the lighting more uniform and natural.

[0063] Optionally, the arrangement of the first groove 40a + second groove 40b and the first groove 40a + second groove 40b + third groove 40c can be set on the upper light-emitting surface 11, or on the lower light-emitting surface 12, or on both light-emitting surfaces 12. This diverse arrangement allows the floor lamp 1000 to flexibly adapt to different indoor scene requirements, improving lighting comfort and ease of use.

[0064] In one specific embodiment, the lamp body 100 further includes a lampshade 30, the groove of which is provided with a stepped recess, the lampshade 30 being disposed on the stepped recess, forming a light-emitting cavity with the light-emitting body 50 and the groove 40. The edge thickness of the lampshade 30 is adapted to the depth of the stepped recess, and the width of the stepped recess is not less than the thickness of the first sidewall or the second sidewall.

[0065] In this embodiment, the lampshade 30 is designed to fit into a stepped recess. The lampshade 30 is installed in the recess, thus forming a light-emitting cavity together with the light-emitting element 50 and the groove 40. The stepped recess provides a mounting base, allowing the lampshade 30 to be stably embedded in the lamp body 100 without easily moving or falling off. This also reduces the entry of external dust or debris into the light-emitting cavity, protecting the light-emitting element 50 and extending the lamp's lifespan. The edge thickness of the lampshade 30 matches the depth of the stepped recess, ensuring a secure fit and preventing loosening due to tolerances or vibration, thus improving structural stability. It also enhances dust and water resistance, making it suitable for different indoor and outdoor environments and improving the lamp's durability.

[0066] In one alternative embodiment, the reflective material comprises various types that can be used in different applications to improve luminous efficacy or protect surfaces. These materials include, but are not limited to: foamed reflective materials: these materials are typically used in applications requiring lightweight properties while providing a certain level of reflectivity; mirrored aluminum: this material has high reflectivity and can reflect most light; and nano-reflective films: nano-reflective films are an advanced material with excellent reflectivity, up to 98%, and good impact resistance and thermal stability, which can improve the luminous efficacy of lighting fixtures.

[0067] The embodiments described above are merely examples of several implementations of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application.
