Description
Technical Field
[0001] This utility model belongs to the field of lighting technology, and specifically relates to a lighting device. Background Technology
[0002] As living standards improve, people's requirements for their living environment also increase. However, some existing living environments are limited by external factors, making it difficult for residents to experience the natural environment. For example, residents cannot experience blue skies and white clouds, sunrises or sunsets. This has led to the widespread popularity of lighting devices that can simulate various natural environments.
[0003] In the existing technology, the light emitted by lighting devices that can simulate the sky cannot meet the requirements of users' work or study. For example, when it is necessary to simulate a blue sky, the lighting device can only emit blue light, which may have a negative impact on the user's visual health in this environment and cannot meet the user's work or study requirements.
[0004] Therefore, existing lighting devices have the drawback of failing to meet the needs of users for work or study while simulating the sky. Utility Model Content
[0005] The purpose of this utility model embodiment is to provide a lighting device that simulates the sky while making the light in the illuminated space conform to the target spectrum, thereby creating a healthier environment for the user's vision and meeting the user's work or study requirements.
[0006] This utility model embodiment provides a lighting device, including:
[0007] A surface-emitting component, the surface-emitting component being used to emit first light having a first spectrum;
[0008] A side-emitting component is disposed on the side of the surface-emitting component. The side-emitting component is used to emit a second light with a second spectrum. The optical axis of the first light emitted by the surface-emitting component is parallel to the optical axis of the second light emitted by the side-emitting component. At least a portion of the illumination range of the surface-emitting component and the illumination range of the side-emitting component coincide in the target illuminated area to form a synthetic light with a target spectrum.
[0009] Optionally, the side-emitting component is arranged around the surface-emitting component, and a gap is provided between the side-emitting component and the surface-emitting component, wherein the luminous intensity of the side-emitting component is greater than the luminous intensity of the surface-emitting component.
[0010] Optionally, the ratio of the area of the space enclosed by the side-emitting components to the area occupied by the surface-emitting components is 1.05 to 1.5, and the ratio of the luminous intensity of the side-emitting components to the luminous intensity of the surface-emitting components is 15 to 30.
[0011] Optionally, the side-emitting component includes a plurality of first light-emitting modules, which are distributed around the outside of the surface-emitting component, and the light intensity of the plurality of first light-emitting modules is greater than the light intensity of the surface-emitting component.
[0012] Optionally, the first light-emitting module includes at least one light-emitting unit, which is a spotlight. The spotlight includes a side light-emitting element and a reflector. The reflector is disposed on the light-emitting side of the side light-emitting element and is configured to reflect the emitted light from the side light-emitting element and reduce its light-emitting angle.
[0013] Optionally, the spotlight is tilted toward the surface light-emitting component, and the angle between the optical axis of the spotlight and the optical axis of the surface light-emitting component is greater than zero and less than or equal to 15°.
[0014] Optionally, the side-emitting component further includes at least two second light-emitting modules, which are alternately distributed with the first light-emitting module.
[0015] Optionally, the surface light-emitting component includes a housing, a surface light source, and a light-emitting plate. The surface light source is disposed inside the housing, and the light-emitting plate is disposed on the light-emitting side of the surface light source and connected to the housing. The side light-emitting component is connected to the housing, and at least a portion of the side light-emitting component protrudes from the light-emitting plate along the optical axis direction of the first light emitted by the surface light-emitting component.
[0016] Optionally, the housing includes a base and a bracket connected to the base, and the light-emitting plate is disposed on the side of the bracket opposite to the base;
[0017] The surface light source is disposed on the base, and the optical axis of the first light emitted by the surface light source is parallel to the axis of the light-emitting plate;
[0018] Alternatively, the surface light-emitting component may further include a surface light guide plate parallel to the light-emitting plate. The surface light guide plate is connected to the bracket and located between the base and the light-emitting plate. The surface light source is disposed on the side of the surface light guide plate, and the optical axis of the first light emitted by the surface light source intersects with the axis of the light-emitting plate. The surface light guide plate is used to conduct the light emitted by the surface light source.
[0019] Optionally, the housing further includes an outer shell, which covers the surface light source and the light-emitting plate;
[0020] The surface light-emitting component further includes a window shadow light-emitting element and a light distribution element. Both the window shadow light-emitting element and the light distribution element are disposed on the inner side of the housing. The window shadow light-emitting element emits light in a direction parallel to the extension direction of the housing. The light distribution element is located in the light-emitting path of the window shadow light-emitting element, and the light emitted by the window shadow light-emitting element is refracted by the light distribution element and emitted in a direction away from the housing.
[0021] In this embodiment of the invention, at least a portion of the illumination range of the surface-emitting component and the illumination range of the side-emitting component overlap in the target illuminated area. This allows the first light ray with a first spectrum emitted by the surface-emitting component and the second light ray with a second spectrum emitted by the side-emitting component to overlap in the target illuminated area, forming the desired composite light ray with the target spectrum. For example, the surface-emitting component emits blue light, creating a blue sky effect on its light-emitting surface, while the side-emitting component emits white light. The blue and white light overlap in the target illuminated area to form the desired composite light ray with the target spectrum, meeting the user's work or study requirements. Simultaneously, when looking at the lighting device, the user can still see the blue sky effect created by the blue light emitted by the surface-emitting component on its light-emitting surface. Thus, the lighting device simulates the sky while forming a composite light ray with the target spectrum in the target illuminated area, thereby creating a healthier visual environment for the user and meeting their work or study requirements.

[0051] The technical solutions of the present utility model will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0052] The terms "first," "second," etc., used in the specification and claims of this utility model are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this utility model can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, the first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0053] The lighting device provided by the present invention will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0054] refer to Figures 1-19The present invention provides an illumination device that may include a surface light-emitting component 100 and a side light-emitting component 200. The side light-emitting component 200 may be disposed on the side of the surface light-emitting component 100. The surface light-emitting component 100 may be used to emit a first light with a first spectrum, and the side light-emitting component 200 may be used to emit a second light with a second spectrum. The optical axis of the first light emitted by the surface light-emitting component 100 and the optical axis of the second light emitted by the side light-emitting component 200 are parallel, that is, the surface light-emitting component 100 and the side light-emitting component 200 may emit light toward the same side. Furthermore, at least a portion of the illumination range of the surface light-emitting component 100 and the illumination range of the side light-emitting component 200 may overlap in the target illuminated area to form a composite light with a target spectrum. In other words, the first light and the second light may overlap in the target illuminated area to form a composite light with a target spectrum.
[0055] For example, the surface-emitting component 100 emits blue light, creating a blue sky effect on its light-emitting surface, while the side-emitting component 200 emits white light. The blue and white light overlap in the target illuminated area to form the desired composite light with the target spectrum, meeting the user's work or study requirements. Simultaneously, the user can still see the blue sky effect created by the blue light emitted by the surface-emitting component on its light-emitting surface when looking at the lighting device. In this way, the lighting device can simulate the sky while simultaneously creating composite light with the target spectrum in the target illuminated area, thus creating a healthier visual environment for the user and meeting their work or study requirements.
[0056] It should be noted that the target illuminated area refers to a spatial area. Specifically, when the lighting device is a ceiling light, the target illuminated area can be the space between 1 meter and 5 meters below the lighting device.
[0057] In an optional embodiment of this utility model, the side-emitting component 200 can be arranged around the surface-emitting component 100. This increases the overlap range between the side-emitting component 200 and the surface-emitting component 100, thereby increasing the degree of overlap between the first light and the second light, and making the lighting device more likely to meet the user's work or study requirements. Furthermore, a gap 300 can be provided between the side-emitting component 200 and the surface-emitting component 100 so that the area of the space enclosed by the side-emitting component 200 is larger than the area occupied by the surface-emitting component 100. This ensures, on the one hand, that the second light emitted by the side-emitting component 200 can overlap with the first light emitted by the surface-emitting component 100, and on the other hand, avoids the side-emitting component 200 from negatively affecting the scene pattern simulated by the surface-emitting component 100. For example, the second light emitted by the side-emitting component 200 may overlap with the first light on the light-emitting surface of the surface-emitting component 100, causing the color of the pattern simulated by the surface-emitting component to become lighter or the shape of the pattern to change.
[0058] The luminous intensity of the side-emitting component 200 is greater than that of the surface-emitting component 100. This allows the proportion of the second spectrum in the synthesized light to be greater than that of the first spectrum, making it easier to meet the user's work or study requirements. For example, the luminous intensity of the white light emitted by the side-emitting component 200 is greater than that of the blue light emitted by the surface-emitting component 100. Thus, the proportion of white light in the synthesized light is greater than that of blue light, making it easier to meet the user's work or study requirements.
[0059] It should be noted that the area of the space enclosed by the side-emitting components 200 refers to the area of the space enclosed by the overall frame of the side-emitting components 200. Specifically, it can be the area of the space enclosed by the fixing frame 220 as described below. For example, if the overall frame of the side-emitting components 200 is circular and the overall structure of the surface-emitting components 100 is also circular, then the area of the space enclosed by the side-emitting components 200 being greater than the area occupied by the surface-emitting components 100 can be expressed as: the diameter of the side-emitting components 200 being greater than the diameter of the surface-emitting components 100. Alternatively, if the overall frame of the side-emitting components 200 is square, then the area of the space enclosed by the side-emitting components 200 can be the planar area of the square structure. Of course, the overall frame of the side-emitting components 200 can also be other shapes.
[0060] Of course, the gap 300 may not be provided between the side-emitting component 200 and the surface-emitting component 100.
[0061] In other embodiments, the side-emitting component 200 may not be disposed around the surface-emitting component 100, and the gap 300 between the side-emitting component 200 and the surface-emitting component 100 may not be provided.
[0062] In an optional embodiment, the ratio of the area of the space enclosed by the side-emitting component 200 to the area occupied by the surface-emitting component 100 can be 1.05 to 1.5, and the ratio of the luminous intensity of the side-emitting component 200 to the luminous intensity of the surface-emitting component 100 can be 15 to 30.
[0063] Optionally, the surface light-emitting component 100 can be a circular structure, and the side light-emitting component 200 can be a ring structure. The diameter of the surface light-emitting component 100 can be 550mm to 900mm, and the maximum diameter of the side light-emitting component 200 can be 600mm to 1200mm.
[0064] The luminous intensity of the surface-emitting component 100 can be 280cd~350cd, and the luminous intensity of the side-emitting component 200 can be 6000cd~8000cd.
[0065] In an optional embodiment of this utility model, the side-emitting component 200 may include a plurality of first light-emitting modules 210, which may be distributed around the outer side of the surface-emitting component 100. This increases the overlap range between the second light and the first light, thereby increasing the illumination range of the synthesized light and making the lighting device more likely to meet the user's lighting needs. Furthermore, the luminous intensity of the plurality of first light-emitting modules 210 is greater than the luminous intensity of the surface-emitting component 100. Thus, the light emitted by each first light-emitting module 210, after overlapping with the first light emitted by the surface-emitting component 100, can form a synthesized light with the target spectrum, making it easier to meet the user's requirements for synthesized light. In addition, the use of a plurality of first light-emitting modules 210 in the side-emitting component 200, compared to using a ring-shaped light-emitting element, helps reduce the number of LED chips and lowers costs.
[0066] The side-emitting component 200 may also include a fixing frame 220, which may be arranged around the surface-emitting component 100. A plurality of first light-emitting modules 210 may be arranged on the fixing frame 220 so that the plurality of first light-emitting modules 210 are distributed around the outside of the surface-emitting component 100.
[0067] Here, the light emission direction of each first light-emitting module 210 is the same as the light emission direction of the surface light-emitting component 100. Specifically, each first light-emitting module 210 and the surface light-emitting component 100 can emit light towards the working surface.
[0068] In other embodiments, the plurality of first light-emitting modules 210 may not be distributed around the outside of the surface light-emitting component 100. For example, the plurality of first light-emitting modules 210 may all be disposed on one side of the surface light-emitting component 100. Alternatively, the side light-emitting component 200 may include an annular light-emitting element, which surrounds the outside of the surface light-emitting component 100 and is coaxially disposed with the surface light-emitting component 100.
[0069] In an optional embodiment, each first light-emitting module 210 may include at least one light-emitting unit, and the light-emitting intensity of the light-emitting unit is greater than the light-emitting intensity of the surface light-emitting component 100, thereby improving the illumination brightness of the side light-emitting component 200.
[0070] Optionally, the light-emitting unit can be a spotlight 211. The spotlight 211 can include a side-emitting element 2111 and a reflector 2112. Here, the side-emitting element 2111 can be disposed on the mounting bracket 220 described above, and the reflector 2112 can be disposed on the light-emitting side of the side-emitting element 2111. Furthermore, the reflector 2112 can be configured to reflect the emitted light from the side-emitting element 2111 and reduce its emission angle. In this way, the reflector 2112 can concentrate the light emitted by the side-emitting element 2111, improve the light energy utilization rate, thereby increasing the focusing effect of the light and forming a small-angle light spot on the working surface, which is beneficial to improving the luminous intensity of the side-emitting component 200. It should be noted that the emitted light here can be the second light.
[0071] In other embodiments, the light-emitting unit may not be a spotlight 211; that is, the light-emitting unit may only include the side light-emitting element 2111, without including the reflector 2112.
[0072] Optionally, the side light-emitting element 2111 may include multiple light-emitting elements 21111, which may be arranged in a matrix. This not only helps to reduce the space occupied by the side light-emitting element 2111, but also helps to improve the uniformity of the light emitted by the spotlight 211. Here, the light emission angle of each spotlight 211 can be 10°~25°.
[0073] Of course, the multiple light-emitting elements 21111 do not have to be arranged in a matrix. Specifically, the multiple light-emitting elements 21111 can be arranged in a straight line.
[0074] In this embodiment, multiple light-emitting elements 21111 can emit light of different colors, which can improve the functionality of the lighting device. Users can select the desired color of light according to their actual needs to achieve different functions of the lighting device.
[0075] Optionally, the spotlight 211 may also include a lens 2113, which may be disposed between the side light-emitting element 2111 and the reflector 2112. The lens 2113 may also have an entrance cavity 21131, which is disposed close to the side light-emitting element 2111. The side light-emitting element 2111 may be opposite to the entrance cavity 21131. In this way, more light emitted by the side light-emitting element 2111 may enter the lens 2113 through the entrance cavity 21131.
[0076] Furthermore, the lens 2113 can be a conical structure. The conical surface of the lens 2113 can collect and reflect light, which is then emitted from the side of the lens 2113 facing away from the side light-emitting element 2111. The light rays from the two endpoints of the side light-emitting element 2111 exit at the same angle as the axis of rotational symmetry of the lens 2113. According to the principle of edge rays, the light from other areas of the side light-emitting element 2111 also lies within this angle range, thus the light range is more concentrated, and the light distribution angle can be better. By controlling the edge rays of the side light-emitting element 2111, the color space of the entire light spot can be controlled. Furthermore, as... Figure 16 As shown, a light guide groove can be provided on the side of the lens 2113 facing away from the side light-emitting element 2111. The light guide groove can be coaxially arranged with the lens 2113, and the groove wall can protrude towards the axis of the lens 2113. In this way, the groove wall can refract light to both sides. On the one hand, it can play a role in preventing glare, and on the other hand, it can blur the side light-emitting element 2111, making the lighting device look more beautiful.
[0077] Here, lens 2113 can be a TIR lens.
[0078] In an optional embodiment, the spotlight 211 can be tilted toward the surface light-emitting component 100, and the angle between the optical axis of the spotlight 211 and the optical axis of the surface light-emitting component 100 can be greater than zero and less than or equal to 15°. This allows the light emitted by the spotlight 211 to be tilted toward the surface light-emitting component 100, so that the light emitted by the spotlight 211 can overlap more with the first light emitted by the surface light-emitting component 100, thereby making the lighting device more likely to meet the user's work or study requirements.
[0079] In other embodiments, the spotlight 211 may not be tilted toward the surface light-emitting component 100, and the optical axis of the spotlight 211 may be parallel to the optical axis of the surface light-emitting component 100.
[0080] In an optional embodiment of this utility model, the side-emitting component 200 may further include at least two second light-emitting modules 230. Each second light-emitting module 230 can be disposed within the fixing frame 220, and the second light-emitting modules 230 and the first light-emitting module 210 can be alternately distributed. Specifically, the second light-emitting modules 230 and the first light-emitting module 210 can be alternately distributed circumferentially within the fixing frame 220, thus ensuring uniform light emission from the side-emitting component 200. Optionally, the second light-emitting module 230 may emit light different from that of the first light-emitting module 210 to improve the functionality of the lighting device.
[0081] It should be noted that the second light-emitting module 230 can emit light simultaneously with the first light-emitting module 210, or they can emit light at different times.
[0082] Here, the two opposing walls of the mounting bracket 220 in the optical axis direction of the side-emitting component 200 can be light-transmitting surfaces, so that the side-emitting component 200 emits light in two directions, thereby improving the functionality of the lighting device. For example, the lighting device can emit light with different atmospheres.
[0083] In other embodiments, the side-emitting component 200 may not include the second light-emitting module 230, and the mounting bracket 220 has only one wall surface that is light-transmitting in the optical axis direction of the side-emitting component 200, which may be located on the light-emitting side of the surface-emitting component 100.
[0084] In an optional embodiment, the fixing frame 220 may include a support frame 221, at least two first light-transmitting elements 222 and at least two second light-transmitting elements 223. The support frame 221 is provided with at least two first grooves 2211 and at least two second grooves 2212 in a direction parallel to the optical axis of the side-emitting component 200. The openings of the first grooves 2211 and the openings of the second grooves 2212 are arranged opposite to each other. Each second light-emitting module 230 may include a first light-emitting element 231 and a second light-emitting element 232. Each first light-emitting element 231 may be disposed in each first groove 2211, and the light-emitting surface of each first light-emitting element 231 may face the opening of each first groove 2211. Each second light-emitting element 232 may be disposed in each second groove 2212, and the light-emitting surface of each second light-emitting element 232 may face the opening of each second groove 2212. In this way, the first light-emitting elements 231 and the second light-emitting elements 232 may emit light to both sides in the optical axis direction. Here, each of the first light-transmitting elements 222 can be respectively disposed at the opening of each of the first grooves 2211 and connected to the support frame 221, and each of the second light-transmitting elements 223 can be respectively disposed at the opening of each of the second grooves 2212 and connected to the support frame 221. Each of the first light-transmitting elements 222 can diffuse the light emitted by each of the first light-emitting elements 231 evenly and softly, and each of the second light-transmitting elements 223 can diffuse the light emitted by each of the second light-emitting elements 232 evenly and softly.
[0085] In this embodiment, both the first light-transmitting element 222 and the second light-transmitting element 223 can be made of silicone material. The first light-emitting element 231 and the second light-emitting element 232 can emit light of the same color or different colors. Furthermore, both the first light-emitting element 231 and the second light-emitting element 232 can be arc-shaped strip structures or elongated strip structures.
[0086] Optionally, the support frame 221 may also be provided with at least two light-emitting module mounting slots, and each first light-emitting module 210 may be respectively disposed in each light-emitting module mounting slot. Each light-emitting module mounting slot and each first groove 2211 may be alternately distributed in the circumferential direction of the support frame 221.
[0087] In an optional embodiment of this utility model, the surface light-emitting component 100 may include a housing 1000, a surface light source 120, and a light-emitting plate 150. The surface light source 120 may be disposed within the housing 1000, and the light-emitting plate 150 may be disposed on the light-emitting side of the surface light source 120 and connected to the housing 1000. The side light-emitting component 200 may be connected to the housing 1000, and at least a portion of the side light-emitting component 200 may protrude from the light-emitting plate 150 along the optical axis direction of the first light emitted by the surface light-emitting component 100, that is, at least a portion of the side light-emitting component 200 may protrude from the light-emitting surface of the surface light-emitting component 100. In this way, the second light emitted by the side light-emitting component 200 can more easily coincide with the first light emitted by the surface light-emitting component 100.
[0088] In other embodiments, the side-emitting component 200 may not protrude from the light-emitting plate 150 along the light-emitting direction of the surface-emitting component 100.
[0089] In an optional embodiment, the housing 1000 may include a base 110 and a bracket 130, the bracket 130 may be connected to the base 110, and the light-emitting plate 150 may be disposed on the side of the bracket away from the base 110.
[0090] Here, the end of the side-emitting component 200 that is away from the base 110 can be flush with the end of the surface-emitting component 100 that is away from the base 110, which helps to improve the aesthetics of the lighting device.
[0091] In one embodiment, the surface light source 120 can be mounted on the base 110, and the optical axis of the first light emitted by the surface light source 120 can be parallel to the axis of the light-emitting plate 150. Specifically, the light-emitting side of the surface light source 120 is away from the base 110. In this way, a direct-lit light source can be formed. Of course, the optical axis of the first light emitted by the surface light source 120 may not be parallel to the axis of the light-emitting plate 150.
[0092] In another embodiment, the surface light-emitting assembly 100 may further include a surface light guide plate. The surface light guide plate may be parallel to the light-emitting plate 150, and it may be connected to the bracket 130 and located between the base 110 and the light-emitting plate 150. The surface light source 120 may be disposed on the side of the surface light guide plate. The optical axis of the first light emitted by the surface light source 120 intersects the axis of the light-emitting plate 150. The surface light guide plate can be used to conduct the light emitted by the surface light source 120. Thus, the emission direction of the light from the surface light source 120 can be changed by the surface light guide plate, making the light emitted by the surface light source 120 parallel or nearly parallel to the axis of the light-emitting plate 150. Of course, the surface light-emitting assembly 100 may also not include a surface light guide plate.
[0093] In an optional embodiment, the housing 1000 may further include an outer shell 140, which may cover the surface light source 120 and the light-emitting plate 150 to protect them. In some embodiments, the outer shell 140 may be connected to the base 110, and the bracket 130 may be disposed inside the outer shell 140.
[0094] The surface light-emitting component 100 may further include a window shadow light-emitting element 160 and a light distribution element 170. Both the window shadow light-emitting element 160 and the light distribution element 170 can be disposed inside the housing 140. Specifically, the window shadow light-emitting element 160 can be mounted on the bracket 130. The window shadow light-emitting element 160 can emit light in a direction parallel to the extending direction of the housing 140, that is, the light emitted by the window shadow light-emitting element 160 can be parallel to the light emitted by the surface light source 120. The light distribution element 170 can be located in the light-emitting path of the window shadow light-emitting element 160, and the window shadow light-emitting element 160 is emitted away from the housing 140 after being refracted by the light distribution element 170. In this way, the light distribution element 170 can refract the light emitted by the window shadow light-emitting element 160 to the side of the light distribution element 170 away from the housing 140, thereby forming a light-emitting area on the side of the light-emitting surface of the surface light source 120 to simulate the effect of sunlight shining on one side of a window (e.g., Figure 19 As shown in the image, this creates a window shadow effect, which can improve the user's visual experience.
[0095] Optionally, the window shadow light-emitting element 160 can emit white light, and the light distribution element 170 can guide the white light to the side of the light-emitting surface of the surface light source 120. Specifically, the light distribution element 170 can guide the white light to the side of the transparent plate 152 described below, thereby creating the effect of sunlight shining in and illuminating the window sill, thus visually forming a light-transmitting window effect.
[0096] In other embodiments, the surface light-emitting component 100 may not include the window shadow light-emitting element 160 and the light distribution element 170.
[0097] Optionally, the housing 140 may extend along the light emission direction of the surface light source 120, and the housing 140 may protrude from the light-emitting plate 150 along the light emission direction of the surface light source 120. In this way, the housing 140 can provide installation space for the window shadow light-emitting element 160 and the light distribution element 170.
[0098] The surface-emitting component 100 has a light-emitting area attached to the side of the housing 140 near the light-emitting surface of the surface light source 120. The light-emitting area intersects with the emitted light rays (i.e., the first light rays) from the surface light source 120. Simultaneously, the light-emitting area can emit light at an angle downwards to prevent the light emitted through the light-emitting area from illuminating the non-light-emitting area described below. Here, the housing 140 can be made of an opaque material to create the effect of sunlight entering and illuminating the window sill, visually forming a translucent window effect.
[0099] The surface-emitting component 100 may also have a non-light-emitting area, which is also positioned away from the housing 140. A light / shadow transition zone is formed between the non-light-emitting area and the light-emitting area to simulate sunlight entering from one side, illuminating the window sill on one side of the window, while creating a dark area on the other side of the window sill, making the display effect more realistic. Here, the non-light-emitting area and the light-emitting area can be connected in a ring and together form an annular surface on the outer periphery of the light-emitting surface of the surface light source 120. The light / shadow transition zone is located at the junction of the non-light-emitting area and the light-emitting area. The function of the light / shadow transition zone is to form a light-dark boundary area between the non-light-emitting area and the light-emitting area. Specifically, it can be a continuously changing area from bright to dark, or it can be a clear dividing line.
[0100] The surface light-emitting component 100 may further include a light-shielding member 190, which faces away from the light-emitting area. The light-shielding member 190 and the light-distributing member 170 may together surround the housing 140 on the side near the light-emitting surface of the surface light source 120 to form an illuminated light-emitting area and an unilluminated non-light-emitting area on the outer periphery of the light-emitting surface of the surface light source 120. Optionally, both the light-shielding member 190 and the light-distributing member 170 may be arc-shaped structures.
[0101] In some embodiments, both the window shadow light-emitting element 160 and the light-distributing element 170 can be arc-shaped structures, and both the window shadow light-emitting element 160 and the light-distributing element 170 can be coaxially arranged with the bracket 130. In this way, light-emitting areas and non-light-emitting areas can be formed on the periphery of the surface light-emitting component 100.
[0102] In an optional embodiment, the light-emitting plate 150 may include a diffuser plate 151, which is connected to the inner wall of the support 130. The diffuser plate 151 may be located inside the housing 140 and may cover the surface light source 120 to uniformly distribute the light emitted by the surface light source 120. Specifically, the diffuser plate 151 may diffuse the light, distributing the light emitted by the line light source or point light source into uniform light. Furthermore, the diffuser plate 151 may effectively eliminate the graininess of the light emitted from the surface light source 120 and has the function of diffusing light, that is, the light will be scattered on its surface, spreading the light softly and evenly. After the light is diffused by the diffuser plate 151, the illumination area is larger, the light uniformity is better, and the color is stable.
[0103] The light-emitting plate 150 may also include a transparent plate 152, which is connected to and parallel to the diffuser plate 151. The transparent plate 152 may be disposed on the side of the diffuser plate 151 away from the surface light source 120, and the transparent plate 152 may be used to further diffuse the light.
[0104] Here, the light distribution element 170 can be located on the side of the transparent plate 152 away from the base 110, or a portion of the light distribution element 170 can be arranged around the transparent plate 152.
[0105] Optionally, the surface-emitting component 100 may further include a diffusion ring 180. The diffusion ring 180 can be connected to the bracket 130 and is coaxially arranged with the bracket 130. The diffusion ring 180 can be disposed on the side of the light distribution component 170 away from the side-emitting component 200. In this way, the diffusion ring 180 can diffuse the light emitted by the window shadow light-emitting component 160, so as to better eliminate the graininess of the light emitted from the window shadow light-emitting component 160 and diffuse the light softly and evenly. In optional embodiments, such as Figure 8 As shown, a protrusion 131 can be provided on the outer wall of the bracket 130. The protrusion 131 can be located close to the light-emitting plate 150, and the window shadow light-emitting element 160 can be located on the side of the protrusion 131 facing away from the base 110. The end of the outer shell 140 facing away from the base 110 can be provided with a protruding plate 141 protruding towards the axis of the lighting device. A space for installing the window shadow light-emitting element 160, the light distribution element 170 and the diffusion ring 180 is formed between the protruding plate 141 and the protrusion 131. The two ends of the light distribution element 170 can abut against the window shadow light-emitting element 160 and the protruding plate 141 respectively. The end of the diffusion ring 180 near the base 110 can abut against the lamp plate of the window shadow light-emitting element 160. A slot 142 can be provided on the side of the protruding plate 141 near the base 110. The end of the diffusion ring 180 facing away from the base 110 can be inserted into the slot 142 to fix the diffusion ring 180.
[0106] In an optional embodiment, the surface light source 120 may include at least one first light-emitting unit and at least one second light-emitting unit, which may be staggered. Each first light-emitting unit may include at least two first LEDs, each emitting a different color of light. Similarly, each second light-emitting unit may include at least two second LEDs, each emitting a different color of light, and the color of light emitted by each second LED is different from that emitted by the first LEDs. Thus, different lighting effects can be achieved using first and second LEDs of different colors. Furthermore, the staggered distribution of the first and second light-emitting units makes the light emitted by the surface light-emitting component 100 more uniform in color, thereby simulating different natural environments and natural environments at different times, thus achieving dynamic lighting effects.
[0107] Optionally, each first light-emitting unit and each second light-emitting unit is provided with a light source lens. In this way, the light emitted by each first light-emitting unit and each second light-emitting unit can be concentrated into the center of each light source lens before being emitted, thereby avoiding mutual interference between the light emitted by the first light-emitting unit and the second light-emitting unit.
[0108] In this embodiment, the first light-emitting unit and the second light-emitting unit can be arranged in a circular pattern on the base 110. Specifically, the first light-emitting unit and the second light-emitting unit can be arranged in multiple concentric circles on the base 110. This helps to make the light emitted by the surface light source 120 more evenly distributed, thereby enabling the surface light-emitting component 100 to better simulate natural environmental patterns.
[0109] In an optional embodiment, the window shadow light element 160 may include at least two third lamp beads, each of which can emit light of a different color, thereby enabling the lighting device to simulate more different natural environments.
[0110] In this embodiment of the utility model, the side-emitting component 200 and the surface-emitting component 100 can be connected by at least two connecting arms. Each connecting arm can be distributed along the circumference of the surface-emitting component 100, and both ends of each connecting arm are respectively connected to the surface-emitting component 100 and the side-emitting component 200. Specifically, both ends of each connecting arm are respectively connected to the housing 140 and the fixing frame 220. Furthermore, a first connecting line and a second connecting line are provided inside the connecting arm. One end of the first connecting line can be electrically connected to the side-emitting component 2111, and one end of the second connecting line is electrically connected to the second emitting module 230. The other ends of the first connecting line and the other ends of the second connecting line can both pass through the housing 140 and be electrically connected to the power supply component on the base 110.
[0111] It should be noted that a power supply component can be installed on the base 110. The power supply component can be used to connect to an external power source. The surface light source 120 and the window shadow light element 160 can both be connected to the power supply component.
[0112] In this embodiment, the side-emitting component 200 and the surface-emitting component 100 can be connected by three connecting arms, which can be evenly distributed along the circumference of the surface-emitting component 100. This improves the stability of the connection between the side-emitting component 200 and the surface-emitting component 100.
[0113] Optionally, the base 110 may include a chassis 111 and a bracket 112 connected to the chassis 111. The surface light source 120 may be connected to the side of the chassis 111 opposite to the bracket 112. The bracket 112 may be used to connect to a base mounting mechanism to mount the lighting device onto the base mounting mechanism. Here, the base mounting mechanism may be a ceiling or a wall.
[0114] It should be noted that the lighting fixture can be a ceiling light or a decorative light, etc.
