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 invention is to provide a lighting device that simulates the sky while ensuring that the light in the illuminated space matches the target spectrum, thereby creating a healthier environment for the user's vision and meeting the user's work or study requirements.
[0006] The technical solution of this utility model provides a lighting device, including:
[0007] A surface-emitting component for emitting first light with a first spectrum;
[0008] A side-emitting component is disposed around the surface-emitting component, and at least a portion of the side-emitting component protrudes from the surface-emitting component along the optical axis of the first light emitted by the surface-emitting component. The side-emitting component is used to emit a second light with a second spectrum, and the illumination range of the surface-emitting component covers the illumination range of the side-emitting component to form a synthetic light with a target spectrum.
[0009] Optionally, the emission angle of the side-emitting component is greater than that of the surface-emitting component, and the emission intensity of the side-emitting component is greater than that of the surface-emitting component.
[0010] Optionally, the ratio of the emission angle of the side-emitting component to the emission angle of the surface-emitting component is in the range of 1 to 3.
[0011] Optionally, the ratio of the luminous intensity of the side-emitting component to the luminous intensity of the surface-emitting component is in the range of 1 to 2.5.
[0012] Optionally, the surface-emitting component includes a first light source, and the side-emitting component includes a second light source, wherein the optical axis of the first light emitted by the first light source is parallel to the optical axis of the second light emitted by the second light source of the side-emitting component.
[0013] Optionally, the side-emitting component further includes a side light guide plate, which extends in the direction of the optical axis of the second light emitted by the second light source.
[0014] Optionally, the side light guide plate includes a first light-emitting surface facing the first light source, a second light-emitting surface facing away from the first light source, and a third light-emitting surface perpendicular to the optical axis of the second light emitted by the second light source.
[0015] Optionally, the side-emitting component further includes a transparent lens connected to the surface-emitting component. The transparent lens has a receiving cavity, and the side light guide plate is located in the receiving cavity. The side of the transparent lens facing away from the surface-emitting component has an anti-glare structure.
[0016] Optionally, the surface light-emitting component further includes a housing, a diffuser plate, and a transparent plate, wherein the first light source is disposed inside the housing, the transparent plate is disposed on the light-emitting side of the first light source, and the diffuser plate is disposed between the first light source and the transparent plate;
[0017] The surface light-emitting component further includes a prism, which is disposed between the diffuser plate and the transparent plate, and is used to refract the first light emitted by the first light source to reduce its emission angle.
[0018] Optionally, the prism includes a plurality of prism elements, and each of the prism elements protrudes away from the diffuser plate.
[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:
[0020] In the lighting device provided by the utility model's technical solution, the illumination range of the side-emitting component covers the illumination range of the surface-emitting component. 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, forming the desired composite light 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 can overlap in the illuminated space to form the desired composite light with the target spectrum, meeting the user's work or study requirements. Simultaneously, when looking at the lighting device, the blue light emitted by the surface-emitting component, forming a blue sky on its light-emitting surface, can still be seen. Thus, this lighting device can simulate the sky while forming composite light with the target spectrum in the illuminated space, thereby creating a healthier visual environment for the user and meeting their work or study requirements.

[0056] 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.
[0057] 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.
[0058] 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.
[0059] refer to Figures 1-28 The present invention provides an illumination device that may include a surface light-emitting component 100 and a side light-emitting component 200. 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 side light-emitting component 200 is disposed on the side of the surface light-emitting component 100, and the illumination range of the side light-emitting component 200 covers the illumination range of the surface light-emitting component 100, so that the first light and the second light overlap to form a synthetic light with a target spectrum.
[0060] 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 can overlap in their illuminated space to form the desired synthetic light with the target spectrum, meeting the user's work or study requirements. Simultaneously, when the user looks at the lighting device, they can still see the blue light emitted by the surface-emitting component 100 forming a blue sky on its light-emitting surface. Figure 19 As shown, the lighting fixtures on the left are insufficient for users' work or study needs, while the lighting fixtures on the right are sufficient for users' work or study needs. It should be noted that the illuminated space here refers to the space that the light from the lighting fixture can reach.
[0061] In this way, the lighting device can emit synthetic light that meets the user's work or study requirements while simulating the sky.
[0062] In an optional embodiment, the side-emitting component 200 may be disposed around the surface-emitting component 100, and at least a portion of the side-emitting component 200 protrudes from the surface-emitting component 100 along the optical axis direction of the first light emitted by the surface-emitting component 100, that is, at least a portion of the side-emitting component 200 protrudes from the light-emitting surface of the surface-emitting component 100, so that a portion of the second light emitted by the side-emitting component 200 can irradiate the optical axis of the surface-emitting component 100 and a portion of the second light can irradiate the light-emitting surface of the surface-emitting component 100. This is beneficial to increasing the overlap range of the illumination range of the side-emitting component 200 and the surface-emitting component, thereby facilitating the formation of synthetic light with the target spectrum.
[0063] Optionally, the side-emitting component 200 can be a ring structure, and can be coaxially connected to the surface-emitting component 100. In this way, the second light emitted by the side-emitting component 200 can surround the surface-emitting component 100, ensuring that the overall light emitted by the lighting device meets the user's work or study requirements. For example, the white light emitted by the side-emitting component 200 surrounds the blue light emitted by the surface-emitting component 100, making the light emitted from the entire periphery of the lighting device white light. Within the illumination range of the surface-emitting component 100, the blue light and white light overlap to form a composite light with a target spectrum. This composite light can be a light that is close to white light. Thus, the light within the illuminated space of the entire lighting device can meet the user's work or study requirements.
[0064] In some embodiments, the emission angle of the side-emitting component 200 can be greater than that of the surface-emitting component 100. This allows the second light emitted by the side-emitting component 200 to intersect and coincide with the first light emitted by the surface-emitting component 100, and the luminous intensity of the side-emitting component 200 can be greater than that of the surface-emitting component 100. This results in a greater proportion of the second spectrum in the synthesized light than the first spectrum, making the synthesized light more likely to meet the user's requirements. For example, if the white light emitted by the side-emitting component 200 is stronger than the blue light emitted by the surface-emitting component 100, the proportion of white light in the synthesized light will be greater than the proportion of blue light, making the synthesized light more suitable for the user's work or study needs.
[0065] Here, the emission angle refers to the power angle, which usually refers to the diffusion range of the light emitted by the light source in space. The emission angle of the surface light-emitting component 100 refers to the diffusion range of the first light emitted by the surface light-emitting component 100 in space, and the emission angle of the side light-emitting component 200 refers to the diffusion range of the second light emitted by the side light-emitting component 200 in space.
[0066] It should be noted that, since the luminous intensity of the side-emitting component 200 is greater than that of the surface-emitting component 100, when the distances of the side-emitting component 200 and the surface-emitting component 100 from the working surface are equal, the illuminance value of the side-emitting component 200 is greater than that of the surface-emitting component 100 on the working surface.
[0067] In other embodiments, the luminous intensity of the side-emitting component 200 may be less than or equal to the luminous intensity of the surface-emitting component 100.
[0068] In some embodiments, the luminous flux of the side-emitting component 200 can be greater than that of the surface-emitting component 100. This allows the synthesized light to further meet the user's requirements. It should be noted that the luminous flux here is obtained by integrating the luminous intensity based on a unit solid angle.
[0069] Of course, the luminous flux of the side-emitting component 200 can also be less than or equal to the luminous flux of the surface-emitting component 100.
[0070] It should be noted that when the luminous flux of the surface light-emitting component 100 and the luminous flux of the side light-emitting component 200 are the same, the light emission angle of the side light-emitting component 200 can be appropriately reduced to increase the luminous intensity of the side light-emitting component 200, thereby increasing the illuminance value of the side light-emitting component 200 illuminating the working surface.
[0071] Here, the formula for calculating luminous flux can be: Φv=Kcd×S×V(λ), where Φv is the luminous flux, Kcd is the luminous flux coefficient, S is the ray distribution area of the light source, and V(λ) is the relative visual acuity function of the human eye.
[0072] In some embodiments, the ratio of the emission angle of the side-emitting component 200 to the emission angle of the surface-emitting component 100 can be 1 to 3. Optionally, the ratio of the emission angle of the side-emitting component 200 to the emission angle of the surface-emitting component 100 can be 1.5.
[0073] The ratio of the luminous intensity of the side-emitting component 200 to the luminous intensity of the surface-emitting component 100 can be 1 to 2.5. Optionally, the ratio of the luminous intensity of the side-emitting component 200 to the luminous intensity of the surface-emitting component 100 can be 1.2.
[0074] Optionally, the light emission angle of the surface light-emitting component 100 can be 100°~120°, and the light emission angle of the side light-emitting component 200 can be 120°~175°. Specifically, the light emission angle of the side light-emitting component 200 can be 175°, and the light emission angle of the surface light-emitting component 100 can be 115°.
[0075] The luminous intensity of the surface-emitting component 100 can be 280 cd to 350 cd, and the luminous intensity of the side-emitting component 200 can be 350 cd to 450 cd. Specifically, the peak luminous intensity of the side-emitting component 200 can be 450 cd, and the peak luminous intensity of the surface-emitting component 100 can be 320 cd.
[0076] It should be noted that since the luminous intensity of the side-emitting component 200 is greater than that of the surface-emitting component 100, the color of the synthesized light with the target spectrum is closer to the color of the second light. For example, if the second light is white light and the first light is blue light, the color of the synthesized light is closer to white light. In this way, the synthesized light can be close to white light when it shines on the ground, work surface, wall, or the entire illuminated space. The luminous surface of the surface-emitting component 100 is blue to create the effect of a blue sky. This allows the lighting device to simulate the effect of daytime, and the simulated effect is closer to nature.
[0077] In an optional embodiment, the surface-emitting component 100 may include a first light source 120, and the side-emitting component 200 may include a second light source 210, wherein the optical axis of the first light emitted by the first light source 120 is parallel to the optical axis of the second light emitted by the second light source 210. This configuration allows both the surface-emitting component 100 and the side-emitting component 200 to emit light toward the illuminated area, thereby increasing the brightness of the illuminated area.
[0078] In other embodiments, the optical axis of the first ray emitted by the first light source 120 of the surface light-emitting component 100 may intersect with the optical axis of the second ray emitted by the second light source 210 of the side light-emitting component.
[0079] In an optional embodiment, the side-emitting component 200 may include a side light guide plate 220. The side light guide plate 220 extends along the optical axis of the second light emitted from the second light source 210 and can be used to conduct the light emitted from the second light source 210. This configuration allows the side light guide plate 220 to direct the light emitted from the second light source 210 in multiple directions, enabling the side-emitting component 200 to emit light in multiple directions and increasing the emission angle of the side-emitting component 200 so that the second light emitted by the side-emitting component 200 can coincide with the first light emitted by the surface-emitting component 100.
[0080] Here, at least a portion of the side light guide plate 220 protrudes from the light-emitting surface of the surface light-emitting assembly 100, and the side light guide plate 220 can guide a portion of the second light to the light-emitting surface of the surface light-emitting assembly 100 to form a window shadow effect at the light-emitting surface of the surface light-emitting assembly 100.
[0081] In other embodiments, the side-emitting component 200 may not include the side light guide plate 220, or the side light guide plate 220 may not protrude from the surface-emitting component 100 along the light emission direction of the surface-emitting component 100.
[0082] Optionally, the side light guide plate 220 may include a first light-emitting surface facing the first light source 120, a second light-emitting surface facing away from the first light source 120, and a third light-emitting surface perpendicular to the optical axis of the second light emitted by the second light source 210. That is, the side light guide plate 220 can guide the light emitted by the second light source 210 in the direction facing the first light source 120 and in the direction away from the first light source 120 (i.e., the inner and outer sides of the side light guide plate 220) and in the direction away from the second light source 210, so that the side light-emitting component 200 can achieve multi-directional light emission and increase the light emission angle of the side light-emitting component 200 so that the second light emitted by the side light-emitting component 200 can coincide with the first light emitted by the surface light-emitting component 100. Here, the first light-emitting surface can be a cylindrical light-emitting surface of the side light guide plate 220 facing the first light source 120 in the radial direction, the second light-emitting surface can be a cylindrical light-emitting surface of the side light guide plate 220 facing away from the first light source 120 in the radial direction, and the third light-emitting surface can be an annular light-emitting surface of the side light guide plate 220 in the horizontal direction.
[0083] It should be noted that the inner side of the side light guide plate 220 can be the side facing the optical axis of the surface light-emitting component 100, and the outer side of the side light guide plate 220 can be the side away from the optical axis of the surface light-emitting component 100.
[0084] Of course, the side light guide plate 220 may also include only a second light-emitting surface facing away from the first light source 120 or a third light-emitting surface perpendicular to the optical axis of the second light emitted by the second light source 210.
[0085] In this embodiment, the second light source 210 can be a ring structure, and the second light source 210 can be coaxially arranged with the surface light-emitting component 100.
[0086] In some embodiments, the side-emitting component 200 may further include a transparent lens 230, which may be connected to the surface-emitting component 100, and the transparent lens 230 may be provided with a receiving cavity 234, within which the side light guide plate 220 may be located. In this way, the transparent lens 230 can both diffuse the light guided by the side light guide plate 220 and provide installation space for the side light guide plate 220.
[0087] In other embodiments, the side-emitting component 200 may not include the transparent lens 230, and the side light guide plate 220 may be directly connected to the surface-emitting component 100.
[0088] Optionally, the side of the transparent lens 230 facing away from the light-emitting component 100 may be provided with an anti-glare structure 235. Specifically, the anti-glare structure 235 may be a wavy structure or a frosted surface. This can effectively prevent glare caused by excessive brightness in the illumination area directly below the side-emitting component 200, and ensure that the second light emitted from the second light source 210 is evenly illuminated in the illumination area on the work surface or ground after passing through the transparent lens 230, thereby avoiding glare. It can also blur the shape of the second light source 210, thus preventing the user from seeing the second light source 210 when looking at the side-emitting component 200.
[0089] Of course, one side of the transparent lens 230 away from the light-emitting component 100 can be a plane.
[0090] Here, both the side light guide plate 220 and the transparent lens 230 can be ring structures. The side light guide plate 220 can guide the light from the second light source 210 to the inner side, outer side and one side of the back surface light-emitting component 100 of the transparent lens 230, so that the side light-emitting component 200 can emit light in multiple directions, thereby increasing the illumination range of the side light-emitting component 200 and increasing the overlap range between the second light and the first light, thus making it easier to form a synthetic light with the target spectrum.
[0091] In some embodiments, the surface light-emitting component 100 further includes a housing 1000, a diffuser plate 151, and a transparent plate 152. The first light source 120 can be disposed within the housing 1000. The transparent plate 152 can be disposed on the light-emitting side of the first light source 120 and connected to the housing 1000. The diffuser plate 151 can be disposed between the first light source 120 and the transparent plate 152. The diffuser plate 151 can cover the first light source 120 to uniformly distribute the light emitted by the first light source 120. Specifically, the diffuser plate 151 can diffuse the light, distributing the line light source or point light source into a uniform first light source 120. Furthermore, the diffuser plate 151 can effectively eliminate the graininess of the light emitted from the first light source 120, thus diffusing the light. That is, the light is scattered on its surface, spreading the light softly and evenly. After being diffused by the diffuser plate 151, the light uniformity is good, and the color is stable. The transparent plate 152 can be used to further diffuse the light to improve the illumination effect of the surface light-emitting component 100.
[0092] The surface-emitting component 100 may further include a prism 153, which can be disposed between the diffuser plate 151 and the transparent plate 152. In this way, the diffuser plate 151 and the transparent plate 152 can provide support for the prism 153, and because the prism 153 is located between the diffuser plate 151 and the transparent plate 152, the diffuser plate 151 and the transparent plate 152 can limit the prism 153 to prevent misalignment. Furthermore, the prism 153 can be used to refract the first light emitted by the first light source 120 to reduce its emission angle, thereby reducing the emission angle of the first light source 120. Of course, as... Figure 12 As shown, the prism 153 can be disposed on the side of the diffuser plate 151 opposite to the transparent plate 152.
[0093] Here, the diffuser plate 151, the transparent plate 152, and the prism 153 can form the light-emitting plate 150.
[0094] Of course, the surface light-emitting component 100 may also exclude the prism 153.
[0095] Optionally, the prism 153 may include multiple prism elements 1531, and each prism element 1531 may protrude away from the diffuser plate 151. In this way, the angle at which the light emitted from the first light source 120 is emitted after passing through the prism element 1531 is reduced, thereby reducing the emission angle of the surface light-emitting component 100. Of course, the prism 153 may also include only a single prism element 1531.
[0096] In an optional embodiment, the housing 1000 may be provided with a mounting groove 1010, the second light source 210 may be disposed within the mounting groove 1010, and the transparent lens 230 may include a connecting portion 231 and a light-emitting portion 232. The light-emitting portion 232 may be connected to the connecting portion 231, and the connecting portion 231 may be embedded within the mounting groove 1010 to achieve the connection between the transparent lens 230 and the housing 1000. Here, the light-emitting portion 232 may protrude from the mounting groove 1010 along the light-emitting direction of the surface light-emitting component 100. The connecting portion 231 may be provided with a first receiving cavity 2341, and the light-emitting portion 232 may be provided with a second receiving cavity 2342. The first receiving cavity 2341 and the second receiving cavity 2342 are connected, and the receiving cavity 234 includes the first receiving cavity 2341 and the second receiving cavity 2342, that is, a part of the side light guide plate 220 is located within the first receiving cavity 2341, and another part is located within the second receiving cavity 2342. This configuration allows for the connection between the side-emitting component 200 and the surface-emitting component 100, while also allowing a portion of the side-emitting component 200 to protrude from the surface-emitting component 100.
[0097] Optionally, the housing 1000 may include a base 110 and a bracket 130, with the bracket 130 connected to the base 110, and the light-emitting plate 150 may be disposed at the end of the bracket 130 away from the base 110.
[0098] The housing 1000 may further include an outer shell 140, which surrounds the bracket 130. The outer shell 140 may be a light-transmitting structure to increase the illumination range and improve the spatial illumination effect of the lighting device. The outer shell 140 can be connected to the base 110. A first protrusion 131 may be provided on the outer wall of the bracket 130, and the first protrusion 131 may be positioned close to the light-emitting plate 150. The mounting groove 1010 described above can be formed between the bracket 130, the first protrusion 131, and the outer shell 140. The second light source 210 may be positioned on the side of the first protrusion 131 facing away from the base 110. Here, the first protrusion 131 may be an annular protrusion coaxially arranged with the bracket 130.
[0099] Further, optionally, to improve the stability of the connection between the transparent lens 230 and the housing 1000, such as Figure 24 As shown, a third protrusion 141 may be provided on the inner wall of the outer casing 140, such as... Figure 26 As shown, a fourth protrusion 233 may be provided on the outer wall of the connecting portion 231 of the transparent lens 230. The fourth protrusion 233 may engage with the third protrusion 141 so that the connecting portion 231 and the housing 140 are in axial upper limit engagement with the lighting device.
[0100] like Figure 24 As shown, a second protrusion 132 can be provided at the end of the bracket 130 away from the base 110. Specifically, the second protrusion 132 can be provided at the opening of the mounting groove 1010, thereby reducing the size of the mounting groove 1010 and preventing the connecting part 231 from coming out of the mounting groove 1010. Here, the second protrusion 132 can be located on the side of the third protrusion 141 away from the base 110, thus avoiding affecting the installation and removal of the transparent lens 230. In one embodiment, the first light source 120 can be provided on the base 110, the bracket 130 can be arranged around the first light source 120, and the optical axis of the first light source 120 can be parallel to the axis of the light-emitting plate 150. Specifically, the light-emitting side of the first light source 120 is away from the base 110. This forms a direct-lit light source. Of course, the optical axis of the first light source 120 may not be parallel to the axis of the light-emitting plate 150.
[0101] In another embodiment, the surface-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, connected to the bracket 130, and located between the base 110 and the light-emitting plate 150. A first light source 120 may be disposed on the side of the surface light guide plate, and the optical axis of the first 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 first light source 120. Thus, the emission direction of the first light emitted by the first light source 120 can be changed by the surface light guide plate, making the first light emitted by the first light source 120 parallel or nearly parallel to the axis of the base 110. Of course, the surface-emitting assembly 100 may also not include a surface light guide plate.
[0102] Alternatively, the prism 153 can be a membrane structure or a plate structure.
[0103] In some embodiments, the first 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, with the color of light emitted by each second LED being different from that emitted by each first LED. 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.
[0104] Of course, the first light source 120 may also include multiple LEDs that emit light of the same color.
[0105] 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.
[0106] In some embodiments, the first light-emitting units and the second light-emitting units can be arranged in a circular pattern on the base 110. Specifically, the first light-emitting units and the second light-emitting units can be arranged in multiple concentric circles on the base 110. This helps to make the light emitted by the first light source 120 more evenly distributed, thereby enabling the surface light-emitting component 100 to better simulate natural environmental patterns.
[0107] Optionally, the base 110 may include a chassis 111 and a bracket 112 connected to the chassis 111. The first 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.
[0108] It should be noted that the lighting fixture can be a ceiling light or a decorative light, etc.
[0109] Optionally, the second light source 210 may include at least one third light-emitting unit and at least one fourth light-emitting unit, which may be staggered. Each third light-emitting unit may include at least two third LEDs, each emitting a different color of light. Similarly, each fourth light-emitting unit may include at least two fourth LEDs, each emitting a different color of light, and the color of light emitted by each fourth LED is different from that emitted by each third LED. Thus, different lighting effects can be achieved using third and fourth LEDs of different colors. Furthermore, the staggered distribution of the third and fourth light-emitting units makes the light emitted by the side-emitting component 200 more uniform in color, thereby simulating different natural environments and natural environments at different times, thus achieving dynamic lighting effects.
[0110] Of course, the second light source 210 may also include multiple LEDs that emit light of the same color.
[0111] In an optional embodiment, the light emission direction of the surface light-emitting component 100 is the same as that of the side light-emitting component 200, and at least a portion of the illumination range of the surface light-emitting component 100 coincides with the illumination range of the side light-emitting component 200 in the target illuminated area, so that the first light and the second light overlap in the target illuminated area to form a synthetic light with the target spectrum, that is, the user's work or study requirements can only be met in the target illuminated area.
[0112] Optionally, the side-emitting component 200 is disposed around the surface-emitting component 100, and a gap is provided between the side-emitting component 200 and the surface-emitting component 100. The side-emitting component 200 and the surface-emitting component 100 can be connected by a connecting arm, which can be perpendicular to the optical axis of the surface-emitting component 100. Furthermore, the light emission direction of the side-emitting component 200 can be the same as the light emission direction of the surface-emitting component 100, that is, the side-emitting component 200 emits light in only one direction.
[0113] The side-emitting component 200 includes a mounting frame and several light-emitting modules. The mounting frame surrounds the surface-emitting component 100, and the light-emitting modules are all mounted on the mounting frame and distributed circumferentially along the mounting frame. The light emission direction of each light-emitting module is the same as the light emission direction of the surface-emitting component 100. This increases the overlap range between the second and first light rays, thereby increasing the illumination range of the synthesized light and making the lighting device more likely to meet the user's lighting needs. Each light-emitting module includes several light-emitting units, and the luminous intensity of the light-emitting units is greater than that of the surface-emitting component. This improves the lighting brightness of the side-emitting component 200.
[0114] The light-emitting unit can be a spotlight, where the light-emitting angle can be 10°~25°. The spotlight includes a side-emitting element and a reflector. The side-emitting element is mounted on a fixed frame, and the reflector is located on the light-emitting side of the side-emitting element. The reflector can concentrate the light emitted by the side-emitting element, improving light energy utilization and thus increasing the focusing effect of the light, causing the second light beam to form a small-angle light spot on the working surface, thereby improving the luminous intensity of the side-emitting component 200. Furthermore, the side-emitting element includes multiple light-emitting elements, which can be arranged in a matrix. This reduces the space occupied by the side-emitting element and improves the uniformity of the light emitted by the spotlight. Here, the side-emitting element can be a second light source.
[0115] Optionally, the spotlight can be tilted toward the surface light-emitting component 100, and the angle between the optical axis of the spotlight and the optical axis of the surface light-emitting component can be greater than zero and less than or equal to 15°. In this way, the light emitted by the spotlight can be tilted toward the surface light-emitting component 100, so that the light emitted by the spotlight 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.
[0116] Optionally, since the first light has a first spectrum, which is a blue light spectrum or a spectrum composed of a blue light spectrum and a white light spectrum, by controlling the brightness or emission angle of the first light emitted by the first light source 120, a dynamic blue pattern or a blue gradient pattern, or a dynamic blue sky and white cloud pattern can be formed on the light-emitting surface of the surface light-emitting component 100. Furthermore, by synchronously controlling the brightness or emission angle of the first light emitted by the second light source 210, a blue gradient pattern or a dynamic blue sky and white cloud pattern can be further formed on the light-emitting surface of the surface light-emitting component 100.
