Description

Technical Field

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

[0002] The blue sky lamp is the first flat panel lamp that uses Rayleigh scattering to simulate the blue sky and sunlight effects on a sunny day. Currently, the blue sky lamps in the industry mix small-size particles into the light guide plate or diffuser, where the relationship between the upper limit of the particle size and the wavelength of the incident light is: π*d / λ<0.3 (d is the particle size, λ is the wavelength of the incident light). Rayleigh scattering is achieved for the incident light of wavelength λ, thereby achieving the effect of clear sky lighting. In addition, in order to visually create the effect of sunlight obliquely shining into the window, an opaque paint layer is sprayed on one to three edges of the transparent frame of the blue sky lamp, and the remaining edges are semi-transparent materials or translucent materials. An LED light board is set behind the translucent edge. When the LED light board is lit, the effect of simulating sunlight obliquely shining into the window is achieved.

[0003] like Figure 1 As shown, it shows an existing blue sky lamp 9, which includes a fixed frame 91, a surface frame 92, a back plate 93, a light-transmitting frame 94, a light guide plate 95, a diffusion plate 96, a reflective layer 97, a first lamp group 98 and a second lamp group 99. The face frame 92 is mounted on the fixed frame 91, and the face frame 92 is arranged near the bottom of the fixed frame 91; the back plate 93 is installed at the top of the fixed frame 91, and a first lamp cavity is formed between the back plate 93 and the fixed frame 91; the light-transmitting frame 94 is detachably connected to the fixed frame 91, and the light-transmitting frame 94 is arranged near the bottom of the fixed frame 91, and a second lamp cavity is formed between the light-transmitting frame 94 and the fixed frame 91; the light guide plate 95, the diffuser plate 96, the reflective layer 97 and the first lamp group 98 are all arranged in the first lamp cavity, and the diffuser plate 96, the light guide plate 95 and the reflective layer 97 are stacked in sequence from the bottom of the fixed frame 91 to the top of the fixed frame 91, the first lamp group 98 is arranged around the circumference of the light guide plate 95, and the LED lamp beads of the first lamp group 98 are arranged toward the light guide plate 95 to achieve the effect of clear sky lighting; the second lamp group 99 is arranged in the second lamp cavity, and the LED lamp beads of the second lamp group 99 are arranged toward the light-transmitting frame 94 to simulate the effect of sunlight obliquely shining into the window.

[0004] However, the existing blue sky lamp 9 has the following shortcomings in achieving the effect of sunlight shining obliquely into the window:

[0005] First, the light-transmitting frame 94 is an integrated structure, so when a problem occurs on one edge of the light-transmitting 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.

[0006] Second, since one to three edges in the light-transmitting frame 94 need to be treated to be opaque, the commonly used treatment methods include the following two: the first is to spray the opaque edges with an opaque paint layer; the second is to form the transparent frame through a two-color injection molding process or a secondary injection molding process to directly form a light-transmitting edge and an opaque edge on the frame; but these two treatment methods have the disadvantage of high production costs.

[0007] Third, in order to ensure that the LED lamp beads of the second lamp group 99 can achieve uniform lighting effects on the light-emitting surface of the light-transmitting edge of the light-transmitting frame 94, the existing practice is to densely arrange the LED lamp beads on the second lamp group 99; however, this practice will greatly increase the operating temperature of the second lamp group 99, resulting in poor lighting stability and short service life of the second lamp group 99. In addition, affected by the installation angle between the second lamp group 99 and the light-emitting surface of the light-transmitting edge, it is still difficult to achieve a very uniform lighting effect on the light-emitting surface of the light-transmitting edge. If Figure 2 As shown, the light-emitting surface of the light-transmitting frame 94 is set to be parallel to the height direction of the blue sky lamp 9. Although it can ensure the uniform lighting effect of the light-emitting surface of the light-transmitting edge, it will affect the overall lighting effect of the blue sky lamp 9, that is, the effect of simulating sunlight obliquely shining into the window is poor. Summary of the invention

[0008] In order to solve the above problems, the main purpose of the utility model is to provide a lamp body structure which is easy to maintain and low in cost.

[0009] Another object of the utility model is to provide a blue sky lamp with the above-mentioned lamp body structure and better lighting effect.

[0010] Another object of the utility model is to provide a lighting system provided with the above-mentioned blue sky lamp.

[0011] In order to achieve the main purpose of the utility model, the utility model provides a lamp body structure, including a fixed frame and a back plate, the fixed frame is a first polygon, the back plate is installed at the top of the fixed frame, and a first lamp cavity is formed between the back plate and the fixed frame, wherein the lamp body structure also includes a light-transmitting frame, the light-transmitting frame includes multiple second sides, the multiple second sides form a second polygon matching the first polygon, a second side is detachably connected to a first side of the first polygon, and a second lamp cavity is formed between the light-transmitting frame and the fixed frame; at least one second side is made of semi-transmitting material or light-transmitting material, and at least one second side is made of shading material.

[0012] As can be seen from the above, the light-transmitting frame is arranged as a split structure, so that when a problem occurs on a second side of the light-transmitting frame (such as wear, scratches, cracks, etc.), the second side can be replaced separately, thereby reducing the maintenance and replacement costs of the blue sky lamp provided with this lamp body structure; in addition, the light-transmitting frame with a split structure can be formed on each side by a common injection molding process (such as using a shading material, a semi-transparent material or a translucent material to make the second side), and there is no need to spray a part of the second side of the light-transmitting frame with an opaque paint layer, which saves production costs while also helping to improve production efficiency.

[0013] A further solution is that a partition is formed on the inner side of the first side, the partitions of two adjacent first sides are connected to each other, and the partition is located between the first lamp cavity and the second lamp cavity; the second side is detachably connected to the first side and the partition respectively.

[0014] As can be seen from the above, the partition is used to support the reflective layer, light guide plate, diffuser plate and first lamp group of the blue sky lamp, and is also used to block the light emitted by the first lamp group to prevent the light emitted by the first lamp group from entering the second lamp cavity and interfering with the second lamp group arranged in the second lamp cavity, thereby ensuring the lighting effect of the blue sky lamp; in addition, the partition can also optimize the connection structure between the second side and the first side.

[0015] A further solution is that the second edge portion has an inclined portion and a bent portion, the inclined portion is inclined to the height direction of the lamp body structure, a first clamping structure is formed on the first side of the inclined portion, the second side of the bent portion is connected to the first side of the inclined portion, the bent portion and the inclined portion are bent, and a second clamping structure is formed on the second side of the inclined portion; a third clamping structure is formed on the protruding side of the third edge portion of the partition, the third clamping structure is clamped and connected to the first clamping structure, and a fourth clamping structure is formed on the bottom of the first edge portion, the fourth clamping structure is clamped and connected to the second clamping structure.

[0016] As can be seen from the above, the above design makes it easier and more convenient to assemble and disassemble the second side portion and the first side portion.

[0017] A further solution is that the fixing frame is made of aluminum alloy; a first heat dissipation groove is provided on the outer side of the first edge along its own extension direction, and the first heat dissipation groove is recessed from the outer side of the first edge to the first lamp cavity; a second heat dissipation groove is provided on the top side of the first edge along the extension direction, and the second heat dissipation groove is recessed from the top surface of the first edge to the bottom surface of the first edge.

[0018] It can be seen from the above that the above design can improve the heat dissipation performance of the fixed frame, so that even if the first lamp group and the second lamp group of the blue sky lamp with the present lamp body structure adopt a high-density lamp bead layout, the fixed frame can meet the heat dissipation requirements of the first lamp group and the second lamp group, thereby ensuring the working stability of the first lamp group and the second lamp group and extending the service life of the first lamp group and the second lamp group.

[0019] A further solution is that the lamp body structure also includes a face frame, which is a third polygon matching the first polygon, and the third side of the third polygon has a side panel and a bottom panel, the side panel is covered on the outer side of the first side, and the bottom panel is covered on the bottom of the first side.

[0020] As can be seen from the above, the setting of the face frame can improve the lighting effect of the blue sky lamp with the lamp body structure; for example, when the bottom of the first side cannot block the bottom of the second side, the bottom plate of the face frame can block the bottom of the second side, thereby improving the lighting effect of the blue sky lamp. In addition, the design of the face frame can also beautify the overall appearance of the lamp body structure and improve the overall aesthetics of the lamp body structure.

[0021] A further solution is that a first grille surface is formed on two oppositely disposed first groove walls of the first heat dissipation groove, and a second grille surface is formed on two oppositely disposed second groove walls of the second heat dissipation groove; the lamp body structure also includes a first locking piece and a second locking piece, the back plate is provided with a first through hole passing through itself, the first locking piece passes through the first through hole and is connected to the first grille surface, the side plate is provided with a second through hole passing through itself, the second locking piece passes through the second through hole and is connected to the second grille surface.

[0022] It can be seen from the above that the provision of the first grille surface and the second grille surface can further enhance the heat dissipation performance of the fixed frame; at the same time, the first grille surface can be connected to the first locking member as a connecting structure of the fixed frame to fix the back panel to the top of the fixed frame; the second grille surface can be connected to the second locking member as a connecting structure of the fixed frame to fix the face frame to the fixed frame.

[0023] A further solution is that the first polygon and the second polygon are both rectangles; one of the four second sides is made of shading material, and the other second sides are made of semi-transparent material or light-transmitting material, or two of the four second sides are made of shading material, and the other second sides are made of semi-transparent material or light-transmitting material, or one of the four third sides is made of shading material, and the other second sides are made of semi-transparent material or light-transmitting material; in the height direction of the lamp body structure, the outer contour of the projection of the second sides is an isosceles trapezoid.

[0024] As can be seen from the above, the number of opaque second sides can be set according to the effect of simulating sunlight obliquely shining into the window required by the blue sky lamp equipped with the lamp body structure. At the same time, the split structural design of the light-transmitting frame makes the production of the blue sky lamp more convenient and flexible, and is conducive to improving the production efficiency and assembly efficiency of the blue sky lamp. By designing the contour of the second side, the effect of simulating sunlight obliquely shining into the window of the blue sky lamp can be improved.

[0026] As can be seen from the above, the blue sky lamp with the above-mentioned lamp body structure has the advantages of being easy to repair and replace, with low repair and replacement costs, easy to produce and assemble, and with low production costs.

[0027] A further solution is that the inner side of the first edge has a mounting surface, and the angle between the mounting surface and the inclined portion is between 15° and 50°; each second LED lamp bead is provided with a polarized lens, the polarized lens has a light-transmitting portion, and the cross-section of the light-transmitting portion is a curved surface with a gradually increasing thickness from the bottom of the first edge to the top of the first edge, and the thickness of the thickest part of the curved surface is 1.5 to 5 times the thickness of the thinnest part.

[0028] It can be seen from the above that by setting the lens and designing the structure of the lens, the blue sky lamp can have a better lighting effect.

[0029] In order to achieve another purpose of the utility model, the utility model provides a lighting system, including a control terminal, wherein the lighting system is also the above-mentioned blue sky light; the blue sky light is electrically connected to the control terminal, and / or the blue sky light and the control terminal exchange information.

[0040] Blue sky lamp embodiment

[0041] Reference Figure 3 and Figure 4 The blue sky lamp 100 includes a lamp body structure 101, a reflective layer 102, a light guide plate 103, a diffusion plate 104, a first lamp group 105 and a second lamp group 106. The lamp body structure 101 includes a fixed frame 1, a back plate 2, a light-transmitting frame 3 and a surface frame 4.

[0042] The fixed frame 1 is preferably an integrated structure, and the fixed frame 1 is in the form of a first polygon, and one side of the first polygon forms a first side portion 113. The back plate 2 is located at the top of the fixed frame 1, and the back plate 2 is connected to the top of the first side portion 113, and a first lamp cavity 111 is formed between the back plate 2 and the fixed frame 1. The light-transmitting frame 3 is installed at the middle and lower part of the fixed frame 1, and a second lamp cavity 112 is formed between the light-transmitting frame 3 and the fixed frame 1; in the height direction of the lamp body structure 101, the second lamp cavity 112 is located at the bottom of the first lamp cavity 111. In the present embodiment, the first polygon is a rectangle; that is to say, in other embodiments, the first polygon may also be other polygons such as a pentagon or a hexagon.

[0043] Combination Figure 5 The reflective layer 102, the light guide plate 103, the diffuser plate 104 and the first lamp group 105 are all arranged in the first lamp cavity 111, and the reflective layer 102, the light guide plate 103 and the diffuser plate 104 are stacked in sequence from the back plate 2 to the light-transmitting frame 3; and the first lamp group 105 is arranged around the circumference of the light guide plate 103, and the first LED lamp beads of the first lamp group 105 are arranged toward the light guide plate 103, so as to create a clear sky lighting effect. Preferably, the first lamp group 105 includes two first light strips 1051, the two first light strips 1051 are distributed along the width direction of the fixed frame 1, and the first light strips 1051 extend along the length direction of the fixed frame 1.

[0044] Combination Figure 6, a partition 114 is formed on the inner side of each first side 113 of the fixing frame 1, and the partitions 114 on two adjacent first sides 113 are combined with each other to avoid a gap between the partitions 114 on the two adjacent first sides 113, thereby preventing the light emitted by the first lamp group 105 from passing through the gap, thereby ensuring the lighting effect of the blue sky lamp 100. In addition, the partition 114 is located between the first lamp cavity 111 and the second lamp cavity 112, so as to cooperate with the light-transmitting frame 3 to isolate the first lamp cavity 111 from the second lamp cavity 112. It can be seen that the partition 114 can not only support the reflective layer 102, the light guide plate 103, the diffuser 104 and the first lamp group 105 of the blue sky lamp 100, but also block the light emitted by the first lamp group 105, thereby preventing the light emitted by the first lamp group 105 from entering the second lamp cavity 112 and interfering with the second lamp group 106 set in the second lamp cavity 112, thereby ensuring the lighting effect of the blue sky lamp 100.

[0045] Combination Figure 7 and Figure 8 The light-transmitting frame 3 is designed as a split structure, that is, the light-transmitting frame 3 includes a plurality of second sides 31, and the plurality of second sides 31 form a second polygon; the shape of the second polygon matches the shape of the first polygon, that is, in this embodiment, the second polygon is also a rectangle.

[0046] A second side portion 31 of the light-transmitting frame 3 is detachably connected to a first side portion 113 of the fixed frame 1 . Preferably, the second side portion 31 is detachably connected to the first side portion 113 and the partition plate 114 , respectively. Preferably, in this embodiment, the second side portion 31 has an inclined portion 311 and a bent portion 312, the inclined portion 311 is inclined in the height direction of the lamp body structure 101, and a first snap-fit ​​structure 3111 is formed on the first side of the inclined portion 311; the second side of the bent portion 312 is connected to the first side of the inclined portion 311, the bent portion 312 and the inclined portion 311 are bent, and the bent portion 312 is roughly parallel to the vertical and horizontal directions of the height direction, and a second snap-fit ​​structure 3121 is formed on the second side of the inclined portion 311; the protruding side of the third side portion 41 of the partition 114 is formed with a third snap-fit ​​structure 1141, and the third snap-fit ​​structure 1141 is snap-fitted and connected to the first snap-fit ​​structure 3111; the bottom of the first side portion 113 is formed with a fourth snap-fit ​​structure 1131, and the fourth snap-fit ​​structure 1131 is snap-fitted and connected to the second snap-fit ​​structure 3121.

[0047] Among them, the first locking structure 3111 is roughly in the shape of a first hook, and the third locking structure 1141 is roughly in the shape of a second hook; the second locking structure 3121 is bent in a step shape, and the fourth locking structure 1131 has a bent hook portion 11311 and a locking hook portion 11312, and a locking groove 11310 is formed between the bent hook portion 11311 and the locking hook portion 11312. When the second side portion 31 is assembled with the first side portion 113, first insert a part of the step-shaped second engaging structure 3121 into the slot 11310, so that the slot 11310 engages and limits the step-shaped second engaging structure 3121; then, the second side portion 31 is rotated with the slot 11310, so that the first hook-shaped first engaging structure 3111 is hooked onto the second hook-shaped third engaging structure 1141 to prevent the first side portion 113 from being separated from the partition 114, thereby completing the assembly of the second side portion 31 and the first side portion 113; this design makes it easier and more convenient to assemble and disassemble the second side portion 31 and the first side portion 113.

[0048] In addition, at least one second side portion 31 of the light-transmitting frame 3 is made of a semi-transparent material or a light-transmitting material, and at least one second side portion 31 is made of a light-shielding material. For example, in the present embodiment, one of the four second sides 31 is made of a light-shielding material, and the remaining second sides 31 are made of a semi-transparent material or a light-transmitting material; as another optional solution, in another embodiment, two of the four second sides 31 are made of a light-shielding material, and the remaining second sides 31 are made of a semi-transparent material or a light-transmitting material; as another optional solution, in another embodiment, one of the four third sides 41 is made of a light-shielding material, and the remaining second sides 31 are made of a semi-transparent material or a light-transmitting material; in the height direction of the lamp body structure 101, the outer contour of the projection of the second side portion 31 is an isosceles trapezoid.

[0049] The light-transmitting frame 3 is set as a split structure, so that when a problem occurs to a certain second side 31 of the light-transmitting frame 3 (such as wear, scratches, cracks, etc.), the second side 31 can be replaced separately, thereby reducing the maintenance and replacement costs of the blue sky lamp 100 provided with the lamp body structure 101; in addition, the light-transmitting frame 3 with a split structure can be formed by a common injection molding process for each side (such as using a light-shielding material, a semi-transparent material or a light-transmitting material to form the second side 31), and there is no need to apply an opaque paint layer to part of the second side 31 of the light-transmitting frame 3. The spraying treatment saves production costs and helps to improve production efficiency. The number of the opaque second sides 31 can be set according to the effect of simulating sunlight obliquely shining into the window required by the blue sky lamp 100 equipped with the lamp body structure 101. At the same time, the split structural design of the light-transmitting frame 3 makes the production of the blue sky lamp 100 more convenient and flexible, and helps to improve the production efficiency and assembly efficiency of the blue sky lamp 100. Through the contour design of the second side 31, the effect of simulating sunlight obliquely shining into the window of the blue sky lamp 100 can be improved.

[0050] The face frame 4 is installed on the fixed frame 1, and the setting of the face frame 4 can enhance the lighting effect of the blue sky lamp 100 provided with the lamp body structure 101. Among them, the face frame 4 is set in a third polygon, and the third polygon matches the first polygon, that is, in the present embodiment, the third polygon is rectangular. In addition, one side of the third polygon forms a third side portion 41, and the third side portion 41 has a side panel 411 and a bottom panel 412; the side panel 411 is covered on the outer surface of the first side portion 113, and the bottom panel 412 is covered on the bottom of the second side portion 31. When in the above-mentioned horizontal direction, if the first side portion 113 cannot completely block the bending portion 312 of the second side portion 31, the bottom panel 412 is preferably also covered on the bending portion 312 of the second side portion 31 that is not blocked by the first side portion 113 (such as Figure 5 As shown); it can be seen that when the bottom of the first side portion 113 cannot block the bottom of the second side portion 31, the bottom plate 412 of the face frame 4 can block the bottom of the second side portion 31, thereby improving the lighting effect of the blue sky lamp 100. In addition, the setting of the face frame 4 can also beautify the overall appearance of the lamp body structure 101 and improve the overall aesthetics of the lamp body structure 101.

[0051] Preferably, the fixing frame 1 is made of aluminum alloy to improve the heat dissipation performance of the fixing frame 1. Preferably, the outer side of the first side portion 113 is provided with a first heat dissipation groove 1132 along its own extension direction, and the first heat dissipation groove 1132 is recessed from the outer side of the first side portion 113 to the first lamp cavity 111, and the top side of the first side portion 113 is provided with a second heat dissipation groove 1133 along the extension direction, and the second heat dissipation groove 1133 is recessed from the top surface of the first side portion 113 to the bottom surface of the first side portion 113; so that even if the first lamp group 105 and the second lamp group 106 adopt a high-density lamp bead layout, the fixing frame 1 still meets the heat dissipation requirements of the first lamp group 105 and the second lamp group 106, thereby ensuring the working stability of the first lamp group 105 and the second lamp group 106 and extending the service life of the first lamp group 105 and the second lamp group 106.

[0052] Furthermore, if Figure 5 As shown, a first grille surface 11321 is formed on two oppositely disposed first groove walls of the first heat dissipation groove 1132, and a second grille surface 11331 is formed on two oppositely disposed second groove walls of the second heat dissipation groove 1133; the setting of the first grille surface 11321 and the second grille surface 11331 can further improve the heat dissipation performance of the fixed frame 1.

[0053] In addition, the lamp body structure 101 further includes a first locking member and a second locking member, and the first locking member and the second locking member are preferably bolts; the back plate 2 is provided with a first through hole 21 penetrating through the back plate 2, and when the back plate 2 is assembled with the fixed frame 1, the first locking member is connected to the first grille surface 11321 on the first edge 113 after passing through the first through hole 21, so that the back plate 2 is reliably fixed to the fixed frame 1; the side plate 411 of the face frame 4 is provided with a second through hole 4111 penetrating through the side plate 4111, and when the face frame 4 is assembled with the fixed frame 1, the second locking member is connected to the second grille surface 11331 on the first edge 113 after passing through the second through hole 4111, so that the face frame 4 is reliably fixed to the fixed frame 1. It can be seen that the first grille surface 11321 can also be connected to the first locking member as a connecting structure of the fixed frame 1; the second grille surface 11331 can also be connected to the second locking member as a connecting structure of the fixed frame 1.

[0054] The second lamp groups 106 are arranged in the second lamp cavity 112, wherein the number of the second lamp groups 106 is equal to and corresponds to the number of the second side portions 31 made of semi-transparent material or translucent material, and the second LED lamp beads of the second lamp groups 106 are arranged toward the inclined portion 311 (i.e., the light-emitting surface of the transparent frame) to simulate the effect of sunlight obliquely shining into the window; as in the present embodiment, the number of the second lamp groups 106 is three groups, and the second LED lamp beads of one group of the second lamp groups 106 are arranged toward the inclined portion 311 of the correspondingly arranged second side portion 31.

[0055] Preferably, the inner side of the first side portion 113 has a mounting surface 1134, and the angle a between the mounting surface 1134 and the inclined portion 311 is preferably between 15° and 50°. Furthermore, each second LED lamp bead is provided with a polarized lens 107, and the polarized lens 107 has a light-transmitting portion 1071, and the cross-section of the light-transmitting portion 1071 is a curved surface with a gradually increasing thickness from the bottom of the first side portion 113 to the top of the first side portion 113; wherein the thickness of the thickest part of the curved surface is preferably 1.5 to 5 times the thickness of the thinnest part. By providing the lens 107 and designing the structure of the lens 107, the blue sky lamp 100 can have a better lighting effect.

[0056] From the above, it can be seen that through the design of the transparent frame of the blue sky lamp 100 and the design of the assembly structure between the transparent frame and the fixed frame 1, the blue sky lamp 100 has the advantage of being easy to repair and replace, and at the same time, its maintenance and replacement costs are low, it is easy to produce and assemble, and the production cost is low.

[0057] Lighting system implementation

[0058] The lighting system includes a control terminal and the blue sky lamp described in the above blue sky lamp embodiment; the blue sky lamp includes a power control module, the control terminal is electrically connected to the power control module, and / or the control terminal and the power control module exchange information. Among them, the control terminal can be a conventional control panel (such as a mechanical switch panel), an intelligent control panel or a remote control. When the control terminal is a conventional control panel, the control terminal is electrically connected to the power control module.
