Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a lamp frame, a clear sky lamp provided with the lamp body, and a lighting system provided with the clear sky lamp. Background Art

[0002] In some relatively closed and / or insufficiently lit places (such as rooms without windows, offices, kitchens, bathrooms, subway stations, hospital wards, etc.), although lamps are installed for lighting, the lighting effects of traditional lamps are generally monotonous and rigid, which makes people who work or live in such places for a long time easily feel depressed; because in such places, it is difficult for the human eye to feel the sunlight, which can easily make people feel irritated over time, which is not conducive to the physical and mental health of people in such places and affects people's lives and work.

[0003] In response to the above-mentioned problems, the lighting industry has developed a new type of lamp - the clear sky lamp. The light emitted by this type of lamp is similar to sunlight, and can be irradiated onto objects (such as walls, floors, etc.) at a specific angle to form a lighting spot with light and dark boundaries to simulate the effect of sunlight slanting into the house, giving people a feeling of being in a sunny natural environment, thereby improving the sensory comfort of people in closed and / or poorly lit spaces, and alleviating people's depression, irritability and other negative emotions.

[0004] like Figure 1 As shown, it shows an existing clear sky lamp, including a lamp frame 91, a front frame 92, a cover plate 93, an optical frame 94, a Rayleigh scattering plate 95, a diffusion plate 96, a reflective layer 97, a first light source 98 and a second light source 99. The front frame 92 is mounted on the lamp frame 91 and is arranged near the bottom of the lamp frame 91; the cover plate 93 is installed at the top of the lamp frame 91, and a first lamp cavity is formed between the cover plate 93 and the lamp frame 91; the optical frame 94 is connected to the lamp frame 91 and is arranged near the bottom of the lamp frame 91, and a second lamp cavity is formed between the optical frame 94 and the lamp frame 91; the light guide plate 95, the diffuser plate 96, the reflective layer 97 and the first light source 98 are all arranged in the first lamp cavity, the diffuser plate 96, the light guide plate 95 and the reflective layer 97 are stacked in sequence from the bottom of the lamp frame 91 to the top of the lamp frame 91, the first light source 98 is arranged around the circumference of the light guide plate 95, and the light-emitting end of the first light source 98 is arranged toward the light guide plate 95 to achieve the effect of clear sky lighting; the second light source 99 is arranged in the second lamp cavity, and the light-emitting end of the second light source 99 is arranged toward the optical frame 94 to simulate the effect of sunlight shining obliquely into the window.

[0005] In order to simulate the effect of sunlight shining obliquely into the window, a light-transmitting area and a light-shielding area need to be formed on the optical frame 94. There are two main existing methods for processing the optical frame 94:

[0006] The first method is to use transparent material to make the entire optical frame 94, and spray an opaque paint layer on the part of the optical frame 94 where the light-shielding area is to be formed; however, this processing method has the disadvantages of cumbersome operation and low production efficiency, and if the paint of the opaque paint layer is not environmentally friendly, it is also easy to cause problems of excessive pollutants (such as formaldehyde).

[0007] The second method is to use a transparent material to make the entire optical frame 94, and to paste an opaque material layer (such as shading paper) on the portion of the optical frame 94 where the shading area is to be formed; however, this processing method has the disadvantages of cumbersome operation and low production efficiency, and the pasting position of the opaque material layer is prone to deviation, thereby affecting the lighting effect of the clear sky lamp. In addition, if the glue used to paste the opaque material is not environmentally friendly, it is easy to have problems with excessive pollutants (such as formaldehyde).

[0008] Furthermore, the existing clear sky lights still have the following deficiencies:

[0009] The optical frame 94 is an integrated structure, so when a problem occurs on a certain edge of the light-transmitting area of ​​the optical frame 94 (such as wear, scratches, cracks, etc.), the entire light-transmitting frame 94 can only be replaced, which makes the repair and replacement costs high; the same is true for the lamp frame 91 and the front frame 92. In addition, once the clear sky lamp is sold, it is difficult for users to adjust the effect of simulating sunlight shining into the house according to their own needs. Specifically, because the optical frame 94 is an integrated structure, and its light-transmitting area and light-shielding area are fixed when it is sold, users cannot adjust and modify it as needed, and the practicality is poor. Summary of the invention

[0010] In order to solve the above problems, the main purpose of the utility model is to provide a lamp frame which is easy to maintain, has low maintenance cost and is environmentally friendly.

[0011] Another object of the utility model is to provide a clear sky lamp provided with the lamp frame.

[0012] Another object of the utility model is to provide a lighting system provided with the above-mentioned clear sky lamp.

[0013] In order to achieve the main purpose of the utility model, the utility model provides a lamp frame, comprising a plurality of edges, wherein at least one of the plurality of edges is made of a shading material by a single-color extrusion process, and the remaining edges are made of a shading material and a light-transmitting material by a two-color extrusion process; the edges made by the two-color extrusion process have a shading area and a light-transmitting area, the shading area is formed by the shading material, and the light-transmitting area is formed by the light-transmitting material, the shading area and the light-transmitting area enclose a first lamp cavity, and the light-transmitting area is located on the inner side of the lamp frame and is arranged close to the bottom of the lamp frame; two adjacent edges are detachably connected by connecting angle codes, and the plurality of edges are connected end to end to form a polygon, and the plurality of edges enclose a second lamp cavity, and the second lamp cavity is located above the first lamp cavity.

[0014] As can be seen from the above, through the design of the lamp frame, it is different from the lamp body structure of the traditional clear sky lamp, and the lamp frame, front frame and optical frame are integrated on the lamp frame, thereby reducing the production cost and simplifying the assembly steps; and by setting the lamp frame as a split structure, when there is a problem with the light-transmitting area of ​​a certain edge (such as wear, scratches, cracks, etc.), the edge can be replaced alone, thereby reducing the maintenance and replacement costs of the clear sky lamp equipped with this lamp frame; in addition, the two-color extrusion process is used to form the edges with optical requirements, so that after the edges are formed, there is no need for additional spraying of opaque paint layer or pasting of opaque material layer on the edges, which is more conducive to improving production efficiency and ensuring the environmental protection of the lamp frame. In addition, the use of extrusion technology to form the edges is also conducive to reducing the production cost of the lamp frame and improving the flexibility of lamp frame production.

[0015] A preferred solution is that the shading area has an outer frame and a supporting plate, and the supporting plate extends from the inner side of the outer frame toward the inside of the lamp frame; the outer frame located at the upper part of the supporting plate and the supporting plate form a second lamp cavity, and the outer frame located at the lower part of the supporting plate, the supporting plate and the light-transmitting area form a first lamp cavity.

[0016] As can be seen from the above, the supporting plate is used to support the relevant lamp groups, reflective layers, Rayleigh scattering plates, diffusion plates and other components of the clear sky lamp equipped with the lamp frame, and is also used to reliably separate the first lamp cavity and the second lamp cavity to avoid mutual interference between the lights in the first lamp cavity and the second lamp cavity, so as to ensure the lighting effect of the clear sky lamp; in addition, the provision of the supporting plate is also conducive to optimizing the position of the light-emitting surface of the light-transmitting area, thereby enhancing the lighting effect of the clear sky lamp simulating sunlight obliquely shining into the window.

[0017] A further solution is that the supporting plate is perpendicular to the height direction of the lamp frame; the light-transmitting area has an inclined plate, a first bent plate and a second bent plate, the first bent plate is perpendicular or inclined to the supporting plate, the first bent plate is connected between the protruding end of the supporting plate and the second end of the inclined plate, the second bent plate is parallel or inclined to the supporting plate, and the second bent plate is connected between the bottom of the outer frame and the second end of the inclined plate; the first horizontal distance between the first end of the inclined plate and the center of the lamp frame is smaller than the second horizontal distance between the second end of the inclined plate and the center of the lamp frame.

[0018] As can be seen from the above, through the design of the light-transmitting area, the edge with optical requirements can have a larger light-emitting surface, thereby further improving the lighting effect of the clear sky lamp simulating sunlight obliquely shining into the window.

[0019] A further solution is that the shading area also has a connecting frame, which is formed around the outer circumference of the outer frame. The connecting frame has a vertical plate extending toward the top of the lamp frame in the height direction of the lamp frame, and a hook is formed at the protruding end of the vertical plate.

[0020] As can be seen from the above, this design allows the lamp frame to be connected to the keel of the ceiling through the vertical plate and the hook thereon, so that the clear sky lamp equipped with this lamp frame can be suitable for indoor spaces with keel ceilings, and improves the convenience of disassembly and assembly of the clear sky lamp and reduces the difficulty of disassembly and assembly of the clear sky lamp.

[0021] Another preferred solution is that the connecting angle code has two bending sections; the edge has a first slot, the first slot passes through the edge along the length direction of the edge, a connecting angle code is connected between two adjacent first slots, and a bending section of the connecting angle code is detachably inserted into a first slot; the edge also has a second slot, the second slot passes through the edge along the length direction, a connecting angle code is connected between two adjacent second slots, and a bending section of the connecting angle code is detachably inserted into a second slot; the first slot and the second slot are both located outside the first lamp cavity and the second lamp cavity.

[0022] As can be seen from the above, the above design makes it easier to assemble and disassemble the connecting angle brackets and the sides. At the same time, a first slot and a second slot are provided so that two adjacent sides can be connected through two connecting angle brackets to improve the reliability and firmness of the connection between the sides.

[0023] Another preferred solution is that the connecting angle code has two connecting blocks, which are bent between each other, and the first connecting block can be detachably inserted into the first lamp cavity of the adjacent first side, and the second connecting block can be detachably inserted into the first lamp cavity of the adjacent second side.

[0024] As can be seen from the above, the structural design of the connecting angle bracket and the matching structural design between the connecting angle bracket and the connecting part are helpful to simplify the structure of the side part.

[0025] A further solution is that a through hole is provided on the edge portion, and a connecting hole is provided on the connecting block, and the connecting hole is arranged to match the through hole and is connected to the through hole.

[0026] As can be seen from the above, this design can improve the reliability and firmness of the connection between the corner bracket and the edge.

[0027] A further solution is that the light-shielding material is ABS, PVC, PP, PBT or PC, the light-transmitting material is ABS, PVC, PP, PBT or PC; and the polygon is a rectangle.

[0028] It can be seen from the above that the above design can improve the thermal conductivity of the lamp frame, so that the lamp frame can stably and reliably dissipate heat for the lamp group arranged therein, so as to ensure the working stability and service life of the lamp group.

[0029] In order to achieve another purpose of the utility model, the utility model provides a clear sky lamp, including a first lamp group, a second lamp group, a cover plate, a reflective layer, a Rayleigh scattering plate and a diffuser, wherein the clear sky lamp also includes the above-mentioned lamp frame; the first lamp group is arranged in the first lamp cavity, and the first light-emitting end of the first lamp group is arranged toward the light-transmitting area; the cover plate is installed on the top of the lamp frame and covers the opening of the second lamp cavity, the second lamp group, the reflective layer, the Rayleigh scattering plate and the diffuser are all arranged in the second lamp cavity, the reflective layer, the Rayleigh scattering plate and the diffuser are stacked in sequence from the bottom of the second lamp cavity to the cover plate, the second lamp group is arranged around the circumference of the Rayleigh scattering plate, and the second light-emitting end of the second lamp group is arranged toward the Rayleigh scattering plate.

[0046] Clear sky lamp first embodiment

[0047] Reference Figure 2 and Figure 3 The clear sky lamp 100 includes a lamp frame 1, a first lamp group 21, a second lamp group 22, a cover plate 3, a reflective layer 4, a Rayleigh scattering plate 5, a diffusion plate 6 and a control power module 7.

[0048] Combination Figure 4 The frame includes a plurality of edges, at least one of the plurality of edges (hereinafter referred to as the "second edge 10") is made of a light-shielding material by a single-color extrusion process, and the remaining edges (hereinafter referred to as the "first edge 11") are all made of a light-shielding material and a light-transmitting material by a two-color extrusion process. The first edge 11 has a light-shielding area 111 and a light-transmitting area 112, the light-shielding area 111 is formed of a light-shielding material, the light-transmitting area 112 is formed of a light-transmitting material, and the light-transmitting area 112 is located inside the lamp frame 1 and is arranged close to the bottom of the lamp frame 1.

[0049] In addition, in this embodiment, the shape of the second side portion 10 is consistent with or similar to that of the first side portion 11, that is, the cross-sectional shape of the second side portion 10 is the same as that of the first side portion 11. The difference between the second side portion 10 and the first side portion 11 is that the area of ​​the second side portion 10 corresponding to the light-transmitting area 112 of the first side portion 11 is formed by a light-shielding material, rather than a light-transmitting material, so that the second side portion 10 as a whole can be formed by a single-color extrusion process. The second side portion 10 is made of a light-shielding material so that the second side portion 10 as a whole is not penetrated by light; while the light-shielding area 111 of the first side portion 11 is made of a light-shielding material so that the light-shielding area 111 of the first side portion 11 is not penetrated by light, and the light-transmitting area 112 of the first side portion 11 is made of a light-transmitting material so that the light-transmitting area 112 of the first side portion 11 can be penetrated by light.

[0050] The shading material is preferably a PC (polycarbonate) material with shading performance; of course, as another optional solution, the shading material can also be made of ABS (acrylonitrile-butadiene-styrene copolymer) material, PVC (polyvinyl chloride plastic) material, PP (polypropylene) material or PBT (polybutylene terephthalate) material with shading performance; it should be noted that the processing method for making PC material, ABS material, PVC material, PP material or PBT material have shading performance belongs to the prior art, so it is not explained in detail here. Similarly, the light-transmitting material or semi-light-transmitting material is preferably a high-transmittance frosted PC material or a high-transmittance smooth PC material with light-transmitting performance; of course, as another optional solution, the light-transmitting material or semi-light-transmitting material can also be made of ABS material, PVC material, PP material or PBT material with light-transmitting performance; it should be noted that the processing method for making PC material, ABS material, PVC material, PP material or PBT material have light-transmitting performance belongs to the prior art, so it is not explained in detail here. By designing the shading material and the light-transmitting material, the thermal conductivity of the lamp frame 1 can be improved, so that the lamp frame 1 can stably and reliably dissipate heat for the first lamp group 21 and the second lamp group 22 arranged therein, so as to ensure the working stability and service life of the lamp groups.

[0051] A plurality of sides (a first side 11 and a second side 10) are connected end to end to form a polygon, so that the lamp frame 1 is a polygonal frame; in addition, a second lamp cavity 1102 is surrounded by the plurality of sides, and the second lamp cavity 1102 is located above the first lamp cavity 1101, and the second lamp cavity 1102 is isolated from the first lamp cavity 1101. Two adjacent sides are detachably connected by connecting angle codes 12, such as the first side 11 and the second side 10 that are adjacently arranged are detachably connected by connecting angle codes 12, the two first sides 11 that are adjacently arranged are detachably connected by connecting angle codes 12, the two second sides 10 that are adjacently arranged are detachably connected by connecting angle codes 12, and so on.

[0052] By designing the lamp frame 1, it is distinguished from the lamp body structure of the traditional clear sky lamp 100, and the lamp frame 1, the front frame and the optical frame are integrated into the lamp frame 1, thereby reducing the production cost and simplifying the assembly steps; and by setting the lamp frame 1 as a split structure, when a problem occurs in the light-transmitting area 112 of a certain side (such as wear, scratches, cracks, etc.), the side can be replaced separately, thereby reducing the maintenance and replacement costs of the clear sky lamp 100 provided with the lamp frame 1; in addition, the two-color extrusion process is used to form the edges with optical requirements, so that after the edges are formed, there is no need for additional spraying of opaque paint layers or pasting of opaque material layers on the edges, which is more conducive to improving production efficiency and ensuring the environmental protection of the lamp frame 1, and the use of extrusion technology to form the edges is also conducive to reducing the production cost of the lamp frame 1 and improving the flexibility of the lamp frame 1 production, such as: edges of different lengths can be produced by the same production equipment and the same production mold.

[0053] In this embodiment, the polygon is a rectangle, that is, the lamp frame 1 is in a rectangular frame shape; and the number of the first side portions 11 is three, and the number of the second side portions 10 is one. Of course, in other embodiments, when the lamp frame 1 is in a rectangular frame shape, the number of the first side portions 11 and the number of the second side portions 10 can also be two; or the polygon is a pentagon, a hexagon, etc., and the number of the first side portions 11 and the second side portions 10 can be set as needed, so no examples are given here.

[0054] Combination Figures 5 to 9 Since the shape of the second side portion 10 is consistent with or similar to the shape of the first side portion 11, only the structure of the first side portion 11 will be introduced below.

[0055] The light shielding area 111 of the first side portion 11 has an outer frame 1111 and a carrier plate 1112, wherein the carrier plate 1112 extends from the inner side of the outer frame 1111 toward the inside of the lamp frame 1, that is, the carrier plate 1112 extends from the inner side of the outer frame 1111 toward the middle of the lamp frame 1. In addition, the outer frame 1111 and the carrier plate 1112 located at the upper part of the carrier plate 1112 enclose a second lamp cavity 1102, while the outer frame 1111, the carrier plate 1112, and the light-transmitting area 112 located at the lower part of the carrier plate 1112 enclose a first lamp cavity 1101. By designing the supporting plate 1112, the supporting plate 1112 can support the second lamp group 22, the reflective layer 4, the Rayleigh scattering plate 5, the diffusion plate 6 and other components; at the same time, the supporting plate 1112 can also separate the first lamp cavity 1101 and the second lamp cavity 1102 to avoid mutual interference between the lights in the first lamp cavity 1101 and the second lamp cavity 1102, thereby ensuring the lighting effect of the clear sky lamp 100; furthermore, the setting of the supporting plate 1112 is also conducive to optimizing the position of the light-emitting surface of the light-transmitting area 112, so as to enhance the lighting effect of the clear sky lamp 100 simulating sunlight obliquely shining into the window.

[0056] Preferably, the bearing plate 1112 is perpendicular to the height direction of the lamp frame 1. Furthermore, the shading area 111 of the first side portion 11 also has a connecting frame 1113, and the connecting frame 1113 is formed around the outer periphery of the outer frame 1111. The connecting frame 1113 has a vertical plate 11131, and the vertical plate 11131 extends toward the top of the lamp frame 1 in the height direction of the lamp frame 1, and a hook 11132 is formed at the extended end of the vertical plate 11131. This design allows the lamp frame 1 to be connected to the keel of the ceiling through the vertical plate 11131 and the hook 11132 thereon, so that the clear sky lamp 100 can be suitable for indoor spaces with keel ceilings, and improves the convenience of disassembly and assembly of the clear sky lamp 100, and reduces the difficulty of disassembly and assembly of the clear sky lamp 100.

[0057] The light-transmitting area 112 has an inclined plate 1121, a first bent plate 1122, and a second bent plate 1123; the first bent plate 1122 is perpendicular or inclined to the carrier plate 1112, and the first bent plate 1122 is connected between the protruding end of the carrier plate 1112 and the second end of the inclined plate 1121; the second bent plate 1123 is parallel or inclined to the carrier plate 1112, and the second bent plate 1123 is connected between the bottom of the outer frame 1111 and the second end of the inclined plate 1121. In addition, the first horizontal distance between the first end of the inclined plate 1121 and the center of the light frame 1 is less than the second horizontal distance between the second end of the inclined plate 1121 and the center of the light frame 1. As in the present embodiment, the first bent plate 1122 is perpendicular to the carrier plate 1112, and the second bent plate 1123 is parallel to the carrier plate 1112. By designing the structure of the light-transmitting area 112 , the first edge portion 11 can have a larger light-emitting surface, so as to further enhance the lighting effect of the clear sky lamp 100 simulating sunlight obliquely shining into the window.

[0058] In this embodiment, the connecting angle code 12 has two bending sections 121, and based on the rectangular frame of the light frame 1, the connecting angle code 12 is matched to be set into an L shape. Among them, the side (the first side 11 and the second side 10) has a first slot 113, and the first slot 113 penetrates the side along the length direction of the side. When the connecting angle code 12 connects two adjacent sides, a bending section 121 of the connecting angle code 12 can be detachably inserted into the first slot 113 of a corresponding connected side (the first side 11 or the second side 10), so that the two adjacent sides are in the shape of Figure 8 Preferably, the edge also has a second slot 114, and the second slot 114 runs through the edge along the length direction of the edge. When the second connecting angle code 12 is used to connect two adjacent edges at the same corner of the lamp frame 1, a bent section 121 of the second connecting angle code 12 can be detachably inserted into the first slot 113 of a corresponding edge, so that the two adjacent edges are as shown. Figure 8The above design makes it easier to disassemble and assemble the connection angle bracket 12 and the edge portion; and by providing two connection angle brackets 12 at the same corner of the lamp frame 1 to connect two adjacent edge portions, the connection between the two adjacent edge portions is more reliable and firm. Furthermore, the first slot 113 is provided on the outer frame 1111 and is located on the outer periphery of the second lamp cavity 1102; the second slot 114 is located on the connection frame 1113 and is located on the outer periphery of the first lamp cavity 1101.

[0059] The first lamp group 21 is arranged in the first lamp cavity 1101, and the first lamp group 21 includes at least one first light strip, and the number of the first light strips is preferably equal to the number of the first side portions 11, so that a first light strip is arranged in a first side portion 11, and the first light-emitting end of the first light strip is arranged toward the light-transmitting area 112 of the first side portion 11, so that the light emitted by the first light strip can penetrate the light-transmitting area 112 to illuminate outside the first side portion 11, thereby cooperating with the second side portion 10 to enable the clear sky lamp 100 to create an excellent effect of sunlight slanting into the window.

[0060] The second lamp group 22, the reflective layer 4, the Rayleigh scattering plate 5 and the diffuser 6 are all arranged in the second lamp cavity 1102, and the cover plate 3 is installed on the top of the lamp frame 1 and covers the opening of the second lamp cavity 1102. The diffuser 6, the Rayleigh scattering plate 5 and the reflective layer 4 are stacked in sequence from the carrier plate 1112 to the cover plate 3; the second lamp group 22 preferably includes two second lamp strips, the second lamp strips extend along the length direction of the lamp frame 1, and the two second lamp strips are distributed along the width direction of the lamp frame 1. In addition, the second lamp strips are arranged around the circumference of the Rayleigh scattering plate 5, and the second light-emitting end of the second lamp strip is distributed toward the Rayleigh scattering plate 5 to simulate the sky effect.

[0061] The control power module 7 is electrically connected to the first light strip of the first light group 21 and the second light strip of the second light group 22 to control the first light group 21 and the second light group 22 to illuminate according to the set mode and ensure the working stability and service life of the first light group 21 and the second light group 22.

[0062] In summary, the design of the lamp frame 1 of the clear sky lamp 100 makes the assembly of the clear sky lamp 100 simpler, which is beneficial to improving production efficiency, and is more convenient to maintain, with lower production costs and more environmentally friendly.

[0063] Clear sky lamp second embodiment

[0064] Reference Figures 10 to 12 The difference between this embodiment and the first embodiment of the clear sky lamp lies in the structure of the connecting angle code, the connecting structure of the connecting angle code and the edge, etc. Specifically, the differences are described below:

[0065] In this embodiment, the first slot and the second slot on the edge 82 (the first edge 82 and the second edge 82) can be eliminated to simplify the structure of the edge 82; correspondingly, the connecting angle code 81 is designed to have two connecting blocks 811, and the two connecting blocks 811 are bent and distributed, wherein the bending angle between the two connecting blocks 811 is equal to the angle between the two adjacent edges 82 of the lamp frame. When the connecting angle code 81 is assembled with the two adjacent edges 82, the first connecting block 811 of the connecting angle code 81 is detachably inserted into the first lamp cavity 821 of the first adjacent edge 82, and the second connecting block 811 is detachably inserted into the first lamp cavity 821 of the second adjacent edge 82. It can be seen that the structural design of the connecting angle code 81 of this embodiment and the matching structural design between the connecting angle code 81 and the connecting part are conducive to simplifying the structure of the edge 82.
