It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. In the following description, a large number of specific details are described in order to facilitate a full understanding of the present application, and the described embodiments are only a part of the embodiments of the present application, but not all the embodiments.

[0056] 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 in the description of the specification herein is for the purpose of describing a specific embodiment only and is not intended to be limiting of the present application.

[0057] In the embodiments of the present application, for the purpose of description but not limitation of the present application, the term "connection" used in the patent application specification and claims of the present application is not limited to physical or mechanical connection, whether direct or indirect. "Up", "down", "above", "below", "left", "right" and the like are only used to indicate relative positional relationship, and when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0058] Please refer to Figure 1 and Figure 2 An embodiment of the present application provides a lamp 100 which can be applied to indoor environments such as homes, schools, office places, and is especially suitable for healthy eye protection lighting in children's rooms. The lamp 100 can realize multi-angle light output and low glare effect with a unified glare rating (UGR) <12 under the cooperation of the upper and lower double light emitting assemblies, and improve the visual comfort and learning efficiency of the user.

[0059] Please refer to Figure 2 and Figure 3In the embodiment, the lamp 100 is substantially in the shape of a round pie, and the lamp 100 comprises an outer frame 10, a back plate 20, a first light emitting assembly 30 and a second light emitting assembly 40. The back plate 20, the first light emitting assembly 30 and the second light emitting assembly 40 are arranged in the outer frame 10. The back plate 20 comprises a first surface 201 and a second surface 202 arranged oppositely. The first light emitting assembly 30 is arranged on the first surface 201, and the first light emitting assembly 30 comprises a first light emitting piece 31 for emitting a first light beam A towards a ceiling. The second light emitting assembly 40 is arranged on the second surface 202, and the second light emitting assembly 40 comprises a second light emitting piece 41 for emitting a second light beam B towards a floor.

[0060] Specifically, the first light emitting piece 31 comprises an aluminum circuit board, a 2835 model lamp bead and a lens. The aluminum circuit board provides electrical connection and physical support for the lamp bead, and its excellent heat dissipation performance can quickly dissipate the heat generated by the lamp bead during operation. The lens is arranged above or in front of the lamp bead and is fixed opposite to the aluminum circuit board, so as to accurately focus and diffuse the light emitted by the 2835 model lamp bead, so that the light can be shot at a specific angle and intensity towards the ceiling, meeting the requirements of the first light emitting assembly 30 on light distribution and lighting effect.

[0061] The second light emitting piece 41 comprises a soft board, a 2835 model lamp bead and a back glue. The soft board provides electrical connection and physical support for the lamp bead, the 2835 model lamp bead provides a stable light source for the second light emitting assembly, and the back glue is used to firmly paste the lamp bead on the corresponding mounting position, so as to ensure that the lamp bead will not move or fall during use of the lamp, thereby ensuring the stability and reliability of the second light emitting assembly 40.

[0062] The direction from the first light emitting assembly 30 to the second light emitting assembly 40 is defined as an optical axis direction S, the first light beam A and the second light beam B are symmetrical about the optical axis direction S, the included angle a between the first light beam A and the optical axis direction S is 0-80 degrees, and the included angle β between the second light beam B and the optical axis is 0-40 degrees.

[0063] In this way, when the first light beam A emitted by the first light emitting assembly 30 is shot towards the ceiling, since the included angle a between the first light beam A and the optical axis direction S is 0-80 degrees, the light can cover the ceiling at a large angle range. The light forms one or more times of diffuse reflection near the ceiling, and the diffuse reflected light becomes soft and uniformly scattered to the surrounding, thereby providing soft supplementary light and overall atmosphere lighting for the indoor. This process greatly reduces the generation of direct glare, so that the indoor light is more comfortable.

[0064] For the second light emitting assembly 40, the included angle β between the second light beam B and the optical axis is 0-40 degrees, which enables the light shot towards the floor to accurately illuminate the floor area, and meanwhile, the strong reflected glare will not be generated due to the large angle.

[0065] In the application scenario of a children's room, children spend a long time in the room for learning, playing and other activities. The unique dual light-emitting component design of the lamp 100 avoids the harm of dazzling glare to children's eyes by reasonably controlling the angle of light, and provides sufficient and soft light. This not only helps to protect the vision of children, but also creates a warm and comfortable learning and living environment, especially suitable for the needs of children's room for healthy eye protection.

[0066] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In the present embodiment, the first light-emitting component 30 further comprises a first mounting seat 32 and a lampshade 33. The lampshade 33, the first mounting seat 32 and the back plate 20 define a mounting space 301, and the first light-emitting piece 31 is arranged in the mounting space 301. Specifically, the first mounting seat 32 is substantially circular, and the first mounting seat 32 is arranged at the central region of the back plate 20. The lampshade 33 is substantially annular, and the inner side of the lampshade 33 is connected to the periphery of the first mounting seat 32, and the other side is connected to the periphery of the back plate 20. In this way, the lampshade 33, the first mounting seat 32 and the back plate 20 form an annular mounting space 301. The first light-emitting piece 31 is an annular light strip, and the first light-emitting piece 31 is arranged outside the first mounting seat 32.

[0067] When the first light-emitting piece 31 is turned on, the light first undergoes multiple reflections and refractions in the closed mounting space 301. The lampshade 33 plays a preliminary role in light scattering and softening, reducing the high-brightness light spots that may be produced when the light is directly emitted outward, so that the light emitted from the mounting space 301 is more uniform and soft. In addition, since the first light-emitting piece 31 is annular and surrounds the outside of the first mounting seat 32, it ensures that the light emission in all directions is relatively balanced, and there is no obvious difference in light intensity. In the process of emitting light to the ceiling, this uniform and soft light distribution can form a more uniform reflection effect on the ceiling. As a result, the entire indoor space can obtain indirect lighting that is uniform and has no obvious bright-dark contrast, reducing the problem of glare caused by uneven or direct strong light. In actual application scenarios, especially in children's rooms where the quality of light is required to be high, this design can create a comfortable and eye-protecting lighting environment for children, helping children to learn and read for a long time without causing visual fatigue, while adding a warm and comfortable atmosphere to the room and improving the overall living experience.

[0068] In the embodiment, the first mounting seat 32 is fixed to the central region of the back plate 20 by screws, so that the connection between the first mounting seat 32 and the back plate 20 is stable and reliable, effectively avoiding displacement of the first mounting seat 32 due to vibration or external force during use of the lamp 100, thereby ensuring the overall stability of the first light-emitting assembly 30.

[0069] The inner side of the lampshade 33 is fixedly connected to the first mounting seat 32 by screws, thereby facilitating tight connection and convenient installation and disassembly, and facilitating maintenance and replacement of internal components of the lamp 100 in the later period

[0070] The outer side of the lampshade 33 extends to form a clamping portion 331, which is clamped into the gap between the back plate 20 and the outer frame 10. In this way, the lampshade 33, the back plate 20 and the outer frame 10 form a tight fitting structure. On the one hand, this clamping method enhances the structural strength of the lamp 100 as a whole, so that the lamp 100 can maintain good form in various environments; on the other hand, it also helps to improve the sealing performance of the lamp 100, reduces the entry of dust, water vapor and other impurities into the mounting space 301, thereby prolonging the service life of the first light-emitting component 31 and other internal components.

[0071] In the embodiment, the first light-emitting assembly 30 further comprises a reflecting member 34 attached to the outer side of the first mounting seat 32. Specifically, the reflecting member 34 comprises a mirror aluminum, and the lampshade 33 is provided with prismatic lines. When the first light-emitting component 31 is turned on, the light is first emitted to the reflecting member 34, which efficiently reflects the light by virtue of the characteristics of the mirror aluminum, changes the propagation direction of the light, and makes the light more concentratedly shoot towards the lampshade 33. When the light shoots towards the lampshade 33, the prismatic lines on the lampshade 33 perform complex refraction and scattering processing on the light. The light is refracted at different angles, and the originally relatively concentrated light is scattered into more uniform light distribution, while the diffusion effect of the light is increased. After being processed by the lampshade 33, the light is transmitted out in a uniform and soft state. The light transmitted through the lampshade 33 shoots towards the ceiling and is reflected on the ceiling. Since the light has been processed by the reflecting member 34 and the lampshade 33 before, it has the characteristics of uniformity and softness, so the reflected light on the ceiling can also be uniformly distributed. Subsequently, these reflected lights continuously diffuse and reflect in the indoor space, interweaving with the light that directly enters the indoor space after being scattered by the lampshade 33. Just like the sunlight in the atmosphere after multiple scattering and reflection, a uniform, soft and layered sunlight field is finally formed in the indoor space.

[0072] In the embodiment, the second light emitting assembly 40 comprises a light guide plate 42 and a reflective sheet 43. The second light emitting member 41 is arranged outside the light guide plate 42. The reflective sheet 43 is arranged between the back plate 20 and the light guide plate 42, and the light guide plate 42 and the reflective sheet are arranged in parallel and spaced apart. The material of the light guide plate 42 comprises optical grade polymethyl methacrylate (PMMA), which has good optical performance and high transparency of more than 92%, and can efficiently conduct light. Its role is to uniformly guide the light emitted by the second light emitting member 41 downward, so that the light emitted from the light guide plate 42 can uniformly illuminate the bottom area, reducing the occurrence of local over-brightness or over-darkness, and providing stable and comfortable basic lighting for the room.

[0073] The material of the reflective sheet 43 is generally a high-reflectivity polyethylene terephthalate (PET) aluminized film. It has very high reflectivity and can reflect the light leaked from the back of the light guide plate 42 back into the light guide plate 42, re-participating in conduction, thereby improving the utilization rate of light and reducing the waste of light. In this way, more light can be guided to the area that needs to be illuminated, enhancing the overall lighting effect of the lamp 100, while also reducing energy consumption to some extent and improving energy utilization efficiency.

[0074] In the embodiment, the second light emitting assembly 40 further comprises a diffusion plate 44 and a prismatic plate 45. The diffusion plate 44 is arranged on the side of the light guide plate 42 away from the reflective sheet 43, and the prismatic plate 45 is arranged on the side of the diffusion plate 44 away from the light guide plate 42. The material of the diffusion plate 44 is polycarbonate (PC). PC material has good optical diffusion performance and can further uniformly diffuse the light emitted by the light guide plate 42. The microstructure inside it can make the light refract and scatter multiple times, thereby dispersing the relatively concentrated light and avoiding the appearance of obvious bright spots or dark areas. This feature makes the light after passing through the diffusion plate 44 can be emitted at a more uniform angle and intensity to the prismatic plate 45, providing a better basis for subsequent light processing and further improving the uniformity of lighting, creating a softer and more comfortable light environment for the room.

[0075] The material of the prismatic plate 45 is acrylate copolymer (ACR). The surface of the prismatic plate 45 is distributed with numerous tiny prismatic structures that can accurately refract and converge the light passing through the diffusion plate 44. Through the careful design of the prismatic angle and arrangement, the prismatic plate 45 can redirect the light to the area that needs to be illuminated, enhance the light intensity in a specific direction, and further optimize the distribution of light. For example, it can more concentratedly shoot light to the ground, improve the effectiveness of illumination, reduce the scattering of light to unnecessary directions, avoid the waste of light, thereby improving the overall light efficiency of the lamp 100 under the premise of ensuring the lighting quality, and making the indoor lighting effect more ideal.

[0076] In the embodiment, the second light-emitting assembly 40 further comprises a buffer 46 arranged between the back plate 20 and the reflector 43. The outer frame 10 is provided with a supporting portion 11 for supporting the periphery of the prismatic plate 45. The material of the buffer 46 includes one of EVA foam, rubber or silicone. When the lamp 100 is subjected to external force, the buffer 46 can buffer these forces, preventing them from being directly transmitted to the relatively fragile optical components such as the reflector 43 and the light guide plate 42, thereby protecting these components from damage and prolonging their service life.

[0077] In the embodiment, the lamp 100 further comprises a second mounting seat 50 for suspending the first mounting seat 32 on the ceiling. Specifically, the second mounting seat 50 comprises a mounting plate 51. The mounting plate 51 is square or circular, and its surface is uniformly distributed with a plurality of mounting holes 511, which can be firmly fixed on the ceiling through expansion bolts or self-tapping screws and the like. The mounting plate 51 is provided with a suspension hook 512. The first mounting seat 32 is provided with a clamping groove 321 adapted to the suspension hook 512.

[0078] When installing the lamp, first, the mounting plate 51 is fixed on the ceiling through expansion bolts or self-tapping screws passing through the mounting holes 511, ensuring that the mounting plate 51 and the ceiling form a stable connection that can bear the weight of the entire lamp. Then, the clamping groove 321 of the first mounting seat 32 is aligned with the suspension hook 512, and the suspension hook 512 is closely embedded in the clamping groove 321 through a clever clamping design. This clamping method not only is simple and fast to install, without the need for additional complex tools and operation steps, but also is stable and reliable in connection.

[0079] Please refer to Figure 7In the embodiment, the lamp 100 further comprises a control unit 60 electrically connected to the first light emitting member 31 and the second light emitting member 41. The control unit 60 is a smart dimming and color adjusting module, which integrates an advanced microprocessor and a smart control algorithm, and can automatically adjust the brightness and color temperature of the first light emitting member 31 and the second light emitting member 41 according to the signal of the ambient light sensor, such as automatically reducing the brightness to save energy in the daytime and increasing the brightness to ensure illumination at night. Meanwhile, the control unit 60 supports manual dimming and color adjusting, and the user can adjust the brightness and color temperature according to his / her own needs and preferences through a remote controller, a mobile phone application, etc. The control unit 60 also has a timing switch function, and the user can pre-set the on and off times to realize intelligent lighting management and provide convenient and comfortable lighting experience.

[0080] In addition, the control unit 60 has a triple smart control function, which brings a full range of convenient control experience. In terms of wall control, the wall control switch has a simple operation interface, and the user can realize basic functions such as lamp switching, brightness adjustment and color temperature switching by pressing it gently. The design conforms to human engineering, and the installation position is convenient to touch. The smart light controller uses wireless connection technology and can be carried around. The user can accurately control the lamp without walking to the wall in any corner of the room. The smart light controller has multiple function keys, in addition to the conventional functions, it may also have reading, leisure, sleep and other preset scene modes. One key click can switch the lamp to the corresponding light mode to meet the lighting needs of different scenes. The smart life mobile phone application control raises the lamp intelligence to a new level. After the user downloads and installs the corresponding application and pairs it with the control unit 60, he / she can control the lamp state anytime and anywhere as long as the mobile phone is connected to the network, such as turning on the lamp in advance to create an atmosphere on the way home from work, and turning off the lamp without getting up when going to bed at night. The application supports remote sharing function, which is convenient for the user to share the control right with family members or friends. Through the triple smart control mode, the user can realize real-time control anywhere and anytime, and bring unprecedented convenience and comfort experience.
