[0031] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] The lamp disclosed in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0033] Please refer to Figure 1-Figure 10 The present application discloses a lamp, which includes a chassis 100 , a first light source panel 200 , a second light source panel 300 , a light blocking frame 400 , a light guide 500 , a first diffusion plate 610 , and a second diffusion plate 630 .

[0034] The chassis 100 is a basic component of the lamp, which can provide a mounting base for other components of the lamp. Specifically, the chassis 100 has a receiving cavity 110 and a light outlet 120. The second diffuser 630 is disposed in the receiving cavity 110, and the second diffuser 630 divides the receiving cavity 110 into an upper space and a lower space, and the lower space is connected to the light outlet 120. The first light source board 200, the second light source board 300 and the light blocking frame 400 are all disposed in the upper space. The first light source board 200 is the main component of the lamp to realize the light-emitting function, and the first light source board 200 The first light source plate 200 and the second light source plate 300 are both facing the light outlet 120, the first light source plate 200 can be a surface light source plate with a larger illumination area, the second light source plate 300 can be a linear light source plate with a smaller illumination area, and the first light source plate 200 and the second light source plate 300 can emit light of different colors, and the light blocking frame 400 is located between the first light source plate 200 and the second light source plate 300, that is, the light blocking frame 400 is used to separate the first light source plate 200 and the second light source plate 300 to avoid the light emitted by the first light source plate 200 and the second light source plate 300 affecting each other.

[0035] For example, when the lamp disclosed in the present application needs to be used as a blue sky lamp, at this time, the first light source panel 200 needs to emit blue light. If the color of the light emitted by the second light source panel 300 is other colors, this will easily affect the presentation effect of the blue light, that is, it will easily affect the light emitting effect of the first light source panel 200. The present application can prevent the light emitted by the first light source panel 200 and the second light source panel 300 from meeting each other by setting a light blocking frame 400, that is, avoiding the first light source panel 200 and the second light source panel 300 from affecting each other.

[0036] The light guide 500 is used to conduct the light emitted by the second light source board 300. Specifically, the light guide 500 is stacked on the second light source board 300, and the light guide 500 is attached to the inner wall of the chassis 100. A part of the light guide 500 is arranged in the upper space, and another part of the light guide 500 is arranged in the lower space, that is, the light guide 500 can pass through the second diffuser 630, or, please refer to Figure 1 The end of the second diffusion plate 630 abuts against the inner wall of the light guide 500, so that a part of the light guide 500 is arranged in the upper space, and the other part of the light guide 500 is arranged in the lower space, so that the light emitted by the second light source panel 300 can pass through the light guide 500 and be emitted from the light outlet 120.

[0037] The first diffuser plate 610 is arranged in the lower space, and the light guide member 500 can guide the light emitted by the second light source panel 300 to the first diffuser plate 610, and emit it from the first diffuser plate 610 to the light outlet 120. The first diffuser plate 610 can make the light emitted by the light guide member 500 more uniform, so that the lamp can present a better lighting effect, and in the light emitting direction of the first light source panel 200, the first light source panel 200 and the second diffuser plate 630 are arranged in sequence, and the second diffuser plate 630 can specifically overlap the light blocking frame 400. Since the light emitted by the first light source panel 200 can be guided to the second diffuser plate 630, and emit it from the second diffuser plate 630 to the light outlet 120, the second diffuser plate 630 can make the light emitted by the first light source panel 200 more uniform, so that the lamp can present a better effect.

[0038] In the present application, the lighting effect of the lamp is achieved by adopting the first light source plate 200 and the second light source plate 300, that is, more light source plates are adopted, and the plurality of light source plates can make the lamp be used as a lighting lamp with greater brightness. Therefore, the lamp disclosed in the present application can solve the problem of low brightness of the lamp involved in the related art. At the same time, since the light blocking frame 400 is located between the first light source plate 200 and the second light source plate 300, that is, the light blocking frame 400 can separate the first light source plate 200 and the second light source plate 300 to avoid the light emitted by the first light source plate 200 and the second light source plate 300 from affecting each other, and since the light emitted by the first light source plate 200 can be guided to the second diffuser plate 630 and emitted from the second diffuser plate 630, the light emitted by the second light source plate 300 can be guided to the first diffuser plate 610 through the light guide 500 and emitted from the first diffuser plate 610, which makes the light emitted by the lamp have a certain spatial stereoscopic sense as a whole, thereby making the visual effect of the lamp better.

[0039] Optionally, since the light blocking frame 400 is located between the first light source board 200 and the second light source board 300, that is, the light blocking frame 400 is arranged around the first light source board 200, in order to allow most of the light emitted by the first light source board 200 to be emitted through the light outlet 120, the inner side wall of the light blocking frame 400 may be coated with a reflective layer, and the reflective layer may reflect the light irradiated on the inner side wall of the light blocking frame 400 to the light outlet 120. Of course, the inner side wall of the light blocking frame 400 may not be coated with a reflective layer.

[0040] Optionally, the second light source plate 300 and the light guide 500 may be disposed around a portion of the first light source plate 200. Figure 1 and Figure 6The light guide member 500 may include a first light guide plate 510, a second light guide plate 520 and a third light guide plate 530 which are connected in sequence, the first light guide plate 510 and the third light guide plate 530 are arranged opposite to each other, and the first light guide plate 510, the second light guide plate 520 and the third light guide plate 530 all include a light guide portion 540 facing the light outlet 120 and protruding from the light blocking frame 400, and at least a part of the light guide portion 540 is arranged in the lower space, so that the light guide portion 540 can guide the light emitted by the second light source panel 300 to the first diffuser plate 610, and at the same time, the outer wall of the light blocking frame 400 is attached to the inner wall of the light guide member 500 to ensure the compactness of the internal structure of the lamp.

[0041] In this embodiment, the first light guide plate 510 and the third light guide plate 530 are both provided with inclined surfaces extending toward the second light guide plate 520, that is, the inclined surfaces are two end surfaces of the light guide member 500. When the light emitted by the second light source plate 300 passes through the inclined end surfaces of the light guide member 500, the lamp can present the effect of U-shaped white window shadow light 800. For details, please refer to Figure 7 , that is, at this time, the effect presented by the lamp is close to the effect presented when the sun shines on the window, that is, the light guide 500 of this structure can make the light emitted by the second light source plate 300 have a clear cutoff line and restore the real window shadow scene when the sun shines on the window. Of course, the first light guide plate 510 and the third light guide plate 530 may not be provided with an inclined surface extending toward the second light guide plate 520.

[0042] In a further embodiment, the present application may only allow the light guiding portion 540 of the first light guide plate 510 and the light guiding portion 540 of the third light guide plate 530 to have an inclined surface extending toward the second light guide plate 520, that is, part of the end surfaces of the first light guide plate 510 and the third light guide plate 530 are set as inclined surfaces. This can reduce the time for cutting the light guide member 500 and ensure the structural strength of the light guide member 500 while achieving the effect of window shadow light 800.

[0043] Optionally, the inclination angle of the inclined surfaces on the first light guide plate 510 and the third light guide plate 530 may be 45 degrees. Of course, it may also be other angles, and the embodiment of the present application does not impose any specific limitation on this.

[0044] Optionally, in order to ensure the stability of the light guide 500 in the accommodating cavity 110, a limiting portion is protruded from the inner wall of the chassis 100, and the limiting portion cooperates with the light guide 500, that is, the limiting portion can limit the setting position of the light guide 500 in the accommodating cavity 110, thereby preventing the light guide 500 from shaking in the accommodating cavity 110.

[0045] Optionally, a reflective portion may be provided on the outer wall of the light guide portion 540, and the reflective portion may be uniformly arranged laser dots, and the reflective portion may reflect the light emitted by the second light source panel 300 to the inner wall of the light guide portion 540 and the first diffuser 610 in sequence, that is, this arrangement may make most of the light emitted by the second light source panel 300 reflected to the inner wall of the light guide portion 540 and emitted through the first diffuser 610, thereby increasing the brightness of the window shadow light 800. Of course, the outer wall of the light guide portion 540 may not be provided with a reflective portion.

[0046] Optionally, the second light source board 300 is provided with a protruding anti-collision block, which is spaced apart from the second light emitting member (i.e., the second light emitting member described later) on the second light source board 300, and the thickness of the anti-collision block is greater than the thickness of the second light emitting member. In the process of installing the light guide member 500, i.e., when the light guide member 500 is superimposed on the second light source board 300, since the thickness of the anti-collision block is greater than the thickness of the second light emitting member, the light guide member 500 will overlap the anti-collision block, i.e., the light guide member 500 will not collide with the second light emitting member, which can avoid damaging the second light emitting member. Of course, the second light source board 300 may not be provided with an anti-collision block.

[0047] Optionally, the second light source panel 300 and the light guide member 500 can both be bent members to achieve a partial setting around the first light source panel 200, and the second light source panel 300 may include a first sub-light source panel 310, a second sub-light source panel 320 and a third sub-light source panel 330 connected in sequence, that is, the second light source panel 300 is an integrated setting and a U-shaped light source panel. During the specific production process, the operator can dig out the U-shaped second light source panel 300 from the middle of the larger light source panel.

[0048] In another embodiment, please refer to Figure 5 The second light source panel 300 includes a first sub-light source panel 310, a second sub-light source panel 320 and a third sub-light source panel 330 which are arranged at intervals, that is, the first sub-light source panel 310, the second sub-light source panel 320 and the third sub-light source panel 330 are independently arranged, and the first sub-light source panel 310, the second sub-light source panel 320 and the third sub-light source panel 330 are all strip-shaped light source panels, and the first sub-light source panel 310 and the third sub-light source panel 330 are located at opposite ends of the second sub-light source panel 320 to form a U-shaped light source panel in combination, and the first light guide plate 510 is stacked on the first sub-light source panel 310, the second light guide plate 520 is stacked on the second sub-light source panel 320, and the third light guide plate 530 is stacked on the third sub-light source panel 330.

[0049] During the specific production process, the operator can cut three strip-shaped sub-light source panels along the edge of the larger light source panel to form a U-shaped second light source panel 300. This cutting method is more convenient, and the structure of the remaining light source panels is still relatively complete, that is, this cutting method will not waste too many light source panels.

[0050] Optionally, the first diffuser 610 may be an annular diffuser, specifically a diffuser frame, and the second diffuser 630 and the first diffuser 610 are overlapped on the light blocking frame 400 in sequence, that is, the first diffuser 610 is overlapped on the second diffuser 630, so that the first diffuser 610 and the second diffuser 630 are in close contact. At this time, the light of the second light source panel 300 conducted by the light guide 500 can be directed to the first diffuser 610 and emitted from the first diffuser 610, that is, this arrangement is not easy to waste the light emitted by the second light source panel 300, and the first diffuser 610 can be attached to the inner side wall of the light guide 500, specifically attached to the inner side wall of the light guide part 540 described above, and the first diffuser 610 can make the light guided by the light guide part 540 more uniform, so that the effect of the window shadow light 800 presented by the lamp is better. Of course, there can be a distance between the first diffuser 610 and the second diffuser 630.

[0051] Optionally, the lamp may further include a control module, and the first light source board 200 and the second light source board 300 are both electrically connected to the control module, that is, the first light source board 200 and the second light source board 300 share the same control module to reduce the structural complexity of the lamp. The first light source board 200 is provided with a plurality of first light-emitting elements 210 arranged at intervals, and the plurality of first light-emitting elements 210 include a first red light-emitting element 211, a first green light-emitting element 212, a first blue light-emitting element 213 and a first white light-emitting element 214. The first white light-emitting element 214 can further enhance the light brightness of the lamp when used as a main lighting lamp, and the first white light-emitting element 214 can simulate the effect of white clouds.

[0052] The control module can control the working state of the first light source panel 200, and the control module can control the luminous intensity of each first light-emitting component 210 so that the first light source panel 200 can present a variety of different luminous colors, that is, the control module adjusts the luminous intensity of each first light-emitting component 210 so that the first light source panel 200 as a whole can present a variety of different colors, and then present a variety of different luminous effects, such as the luminous effect of the blue sky and the sunset, and various parts of the first light source panel 200 can also present different colors, and then present different luminous effects, such as the luminous effect of the coexistence of the blue sky and white clouds, the luminous effect of the coexistence of the sunset and golden clouds, or the luminous effect of the coexistence of the blue sky and the sun.

[0053] It can be seen that the lamp disclosed in this application can not only create natural lighting like the blue sky, but also realize a variety of lighting scenes such as sunset, white clouds and the sun, that is, through the adjustment of the control module, the lamp disclosed in this application can provide a natural and healthy light environment, and the lamp disclosed in this application can be used as a blue sky lamp and also as a main lighting lamp for daily work and life, which makes the lamp disclosed in this application have a wide range of applications.

[0054] The second light source board 300 is provided with a plurality of second light-emitting members arranged at intervals, and the plurality of second light-emitting members may include a second white light-emitting member. The control module may control the working state of the second light source board 300. When the color of the light emitted by the first light source board 200 is white, that is, when the lamp disclosed in the present application is used as a main lighting lamp, the second light source board 300 may further enhance the luminous brightness of the lamp and increase the irradiation area of ​​the lamp, thereby meeting more usage requirements of users. Optionally, the plurality of second light-emitting members may only include a second white light-emitting member.

[0055] In another embodiment, the multiple second light-emitting elements may further include a second red light-emitting element, a second green light-emitting element, and a second blue light-emitting element. The control module may control the luminous intensity of each second light-emitting element so that the second light source panel 300 can present a plurality of different luminous colors. That is, the control module adjusts the luminous intensity of each second light-emitting element so that the second light source panel 300 as a whole can present a plurality of different colors, or so that various parts of the second light source panel 300 can also present different colors, thereby further enriching the luminous effect of the lamp, so that the lamp disclosed in the present application can be widely used in a variety of places.
