Description

Technical Field

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

[0002] Traditional lamps (such as ceiling lamps, strip lights, downlights, spotlights, track lights, etc.) are sufficient to meet the lighting needs of users in daily life, work, commercial use, etc. However, in some places with strong enclosure or insufficient daylighting (such as rooms without windows, offices, kitchens, bathrooms, subway stations, hospital wards, etc.), although the lighting of the lamps can meet the usage requirements, due to the relatively monotonous and rigid lighting effect of traditional lamps, people staying in such places for a long time are prone to a sense of depression.

[0003] In order to solve the deficiencies of traditional lamps when used in places with strong enclosure or insufficient daylighting, a new type of lamp - clear sky lamp (also known as sky lamp, blue sky lamp) has been developed. Such lamps can simulate the effect of clear sky and sunlight shining obliquely into the window, giving people a feeling of being in a natural environment with blue sky and sunlight shining, so as to improve the sensory comfort of people in enclosed spaces or places with insufficient daylighting, and can relieve the depression, irritability and other negative emotions generated by people in enclosed spaces or places with insufficient daylighting. As Figure 1 and Figure 2 shown, an existing clear sky lamp 9 includes a first lamp frame 91, a second lamp frame 92, a lamp cover 93, a cover plate 94, a light-transmitting plate 95, a diffusion plate 96, a light guide plate 97, a reflector 98, a first lamp group 99 and a second lamp group 90. Among them, the first lamp frame 91 and the second lamp frame 92 are nested and installed, the light-transmitting plate 95 is clamped between the first lamp frame 91 and the second lamp frame 92 and is located at the bottom of the clear sky lamp 9; the lamp cover 93 is nested and installed on the second lamp frame 92 and forms a first lamp cavity with the second lamp frame 92, the first lamp group 99 is arranged in the first lamp cavity, and the light-emitting unit of the first lamp group 99 faces the lamp cover 93; the cover plate 94 covers the top of the second lamp frame 92 and forms a second lamp cavity with the second lamp frame 92, and the second lamp cavity is located at the top of the lamp cover 93; the diffusion plate 96, the light guide plate 97 and the reflector 98 are sequentially stacked from the bottom of the second lamp cavity to the cover plate 94, the second lamp group 90 is arranged in the second lamp cavity, and the light-emitting unit of the second lamp group 90 faces the light guide plate 97. When the clear sky lamp 9 works, the second lamp group 90 cooperates with the light guide plate 97 to simulate the lighting effect of the sky, and the first lamp group 99 cooperates with the lamp cover 93 to simulate the effect of sunlight shining into the window. However, the deficiencies of this clear sky lamp 9 are: as Figure 2As shown, the second lamp frame 92 is nested and installed on the outer periphery of the lampshade 93, and the lampshade 93 and the second lamp frame 92 are matched and connected with each other by a snap-on structure, which increases the structural complexity of the lampshade 93 and the second lamp frame 92, makes the assembly difficult, and the second lamp frame 92 and / or the lampshade 93 are prone to deformation and cracking during the assembly process; secondly, when the clear sky lamp 9 is used in a humid environment (such as a toilet, bathroom, kitchen, etc.), moisture can easily penetrate the gap between the second lamp frame 92 and the lampshade 93 into the second lamp cavity, which can easily cause the inside of the lampshade 93 to mold and condense into water droplets, thereby shortening the service life of the first lamp group 99.

[0037] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. Specific embodiments

[0038] The first embodiment of the clear sky lamp

[0039] Referring to Figures 3 to 5 , the clear sky lamp 100 includes a lamp frame 1, an optical front frame 2, a back plate 3, a first lamp group 41, a second lamp group 42, a diffusion plate 51, a light guide plate 52, a reflector 53, and a control unit 6. Among them, the control unit 6 is electrically connected to the first lamp group 41 and the second lamp group 42 respectively to control the first lamp group 41 and the second lamp group 42 to emit light according to a preset mode respectively.

[0040] Combined with Figure 6, the lamp frame 1 has a frame body 11 and a partition 12. Among them, the lamp frame 1 is arranged in a first polygon; for example, in this embodiment, the lamp frame 1 is rectangular. It should be noted that in other embodiments, the lamp frame 1 can also be set into other polygon structures such as triangles, pentagons, hexagons, etc. according to design, use and other requirements to meet the needs of different users and improve the diversity and application range of the clear sky lamp 100. In addition, the lamp frame 1 is preferably formed by an injection molding process, so that the structural strength of the lamp frame 1 can meet the use requirements, reduce the weight of the lamp frame 1, which is beneficial to reducing the overall weight of the clear sky lamp 100 and is also beneficial to reducing the production cost. The partition 12 is located inside the frame body 11 and extends along the circumference of the frame body 11 to form a circumferential partition structure.

[0041] The contour of the optical front frame 2 matches that of the lamp frame 1. The optical front frame 2 is located at the bottom of the lamp frame 1, and at least a part of the optical front frame 2 is embedded in the frame body 11, that is, the frame body 11 surrounds the outer periphery of the optical front frame 2. Combining Figure 7 , the optical front frame 2 has a light-emitting part 21, a first overlapping part 22 and a second overlapping part 23. Among them, the light-emitting part 21 is located between the first overlapping part 22 and the second overlapping part 23. When the optical front frame 2 is assembled with the lamp frame 1, the first overlapping part 22 is welded and fixed to the partition 12, and the second overlapping part 23 is welded and fixed to the frame body 11, so that a first lamp cavity 20 is formed between the optical front frame 2 and the frame body 11, and the optical front frame 2 is located on the lower side of the partition 12.

[0042] In order to ensure the welding position accuracy and welding quality between the lamp frame 1 and the optical front frame 2, a first welding part 111 is arranged on the side of the partition 12 facing the optical front frame 2, and the first welding part 111 is preferably arranged near the protruding end of the partition 12; a second welding part 121 is arranged at the bottom of the frame body 11 or near the bottom of the frame body 11; a third welding part 221 is arranged at the protruding end of the first overlapping part 22, and the third welding part 221 is welded and fixed to the first welding part 111; a fourth welding part 2311 is arranged at the protruding end of the second overlapping part 23, and the fourth welding part 2311 is welded and fixed to the second welding part 121. Among them, one of the first welding part 111 and the third welding part 221 is a welding wire and the other is a welding wire receiving groove, and one of the second welding part 121 and the fourth welding part 2311 is a welding wire and the other is a welding wire receiving groove; for example, in this embodiment, both the first welding part 111 and the second welding part 121 are welding wire receiving grooves, and both the third welding part 221 and the fourth welding part 2311 are welding wires; through the design of each welding part, it is beneficial to improve the welding effect and welding quality between the lamp frame 1 and the optical front frame 2.

[0043] Preferably, a groove 114 is provided at the bottom of the frame body 11. The groove 114 is recessed from the bottom surface of the frame body 11 towards the top of the lamp frame 1, and the second welding portion 121 is formed at the bottom of the groove 114. Correspondingly, the second lapping portion 23 has a first flanging 231, and the fourth welding portion 2311 is formed at the extending end of the first flanging 231. When the lamp frame 1 and the optical front frame 2 are assembled, the first flanging 231 is inserted into the groove 114. This design is conducive to the positioning before welding of the lamp frame 1 and the optical front frame 2, thereby ensuring the relative position accuracy between the two.

[0044] Further, the light-emitting portion 21 of the optical front frame 2 is inclined with respect to the height direction of the clear sky lamp 100, such that the first opening of the light-emitting portion 21 close to the partition plate 12 is smaller than the second opening of the light-emitting portion 21 close to the bottom of the lamp frame 1, so as to enable the clear sky lamp 100 to better simulate the effect of sunlight shining into the window.

[0045] The optical front frame 2 is made of a light-transmitting material through an injection molding process. Among them, the optical front frame 2 is preferably made of a PC (polycarbonate) material with light-transmitting properties. Of course, as other alternative solutions, the light-transmitting material can also be made of an ABS (acrylonitrile-butadiene-styrene copolymer) material, a PVC (polyvinyl chloride plastic) material, a PP (polypropylene) material or a PBT (polybutylene terephthalate) material with light-transmitting properties. It should be noted that the treatment methods for endowing the PC material, ABS material, PVC material, PP material or PBT material with light-transmitting properties belong to the prior art, so no detailed explanation will be given here.

[0046] The first lamp group 41 is arranged in the first lamp cavity 20; combined with Figure 8 , in this embodiment, two baffles 112 are provided on the lamp frame 1. The baffles 112 have the function of blocking light from passing through themselves. The two baffles 112 divide the first lamp cavity 20 into a light-transmitting area and a light-shielding area. The first lamp group 41 is arranged in the light-transmitting area, so that the light emitted by the first lamp group 41 cannot pass through the baffle 112 and the optical front frame 2 in the light-shielding area. The first lamp group 41 can cooperate with the optical front frame 2 to simulate the lighting effect of sunlight shining into the window, and the setting of the baffle 112 can enhance the effect of the clear sky lamp 100 simulating sunlight shining obliquely into the window, thereby enhancing the lighting effect and user experience of the clear sky lamp 100. Preferably, in this embodiment, both the baffle 112 and the lamp frame 1 are made of light-shielding materials, and the baffle 112 and the lamp frame 1 are integrally formed by an injection molding process.

[0047] Among them, the baffle 112 and the lamp frame 1 are preferably made of PC material with light-shielding performance. Of course, as other alternative solutions, the light-shielding material can also be made of ABS material, PVC material, PP material or PBT material with light-shielding performance. It should be noted that the treatment method to endow PC material, ABS material, PVC material, PP material or PBT material with light-shielding performance belongs to the prior art, so no detailed explanation will be given here. In addition, using PC material, ABS material, PVC material, PP material or PBT material to make the lamp frame 1 makes the lamp frame 1 and the like have high thermal conductivity, so that the lamp frame 1 can stably and reliably dissipate heat from the first lamp group 41 and the second lamp group 42, thereby ensuring the stability and service life of the first lamp group 41 and the second lamp group 42 during operation.

[0048] It should be noted that, as other alternative solutions, in other embodiments, the baffle 112 can also be detachably connected to the lamp frame 1. For example, two first slots can be provided on the lamp frame 1, and the two first slots correspond to the two baffles 112 one by one. When it is necessary to install the baffle 112 on the lamp frame 1, the baffle 112 can be inserted into a corresponding first slot. This design can improve the production flexibility of the clear sky lamp 100, assemble the baffle 112 as needed, meet the diversified needs of the clear sky lamp 100, and at the same time can better avoid inventory backlog.

[0049] In addition, combined with Figure 9 , in this embodiment, the two baffles 112 are respectively arranged on two short sides of the rectangular lamp frame 1 and are located at the ends of the corresponding short sides. Correspondingly, the first lamp group 41 includes three first light strips 411, and the three first light strips 411 are respectively arranged on two short sides and one long side of the light-transmitting area.

[0050] The first light strip 411 is installed on the lamp frame 1. Preferably, the first light strip 411 can be fixedly bonded to the lamp frame 1 by an adhesive, and the light-emitting part of the first light strip 411 is arranged towards the optical part of the optical front frame 2. More preferably, the frame body 11 has a bending part 113 at the first lamp cavity 20, and the first lamp group 41 is installed on the bending part 113; and in the cross-section perpendicular to the side of the frame body 11, the bending part 113 is parallel to the light-emitting part 21, or the included angle a between the bending part 113 and the light-emitting part 21 is greater than 0° and less than or equal to 25°; this design can improve the light-emitting effect of the first lamp group 41, and further improve the effect of the clear sky lamp 100 simulating sunlight entering the window.

[0051] The back plate 3 covers the top of the lamp frame 1, and the back plate 3 and the lamp frame 1 enclose a second lamp cavity 30. The second lamp group 42, the diffuser 51, the light guide plate 52 and the reflector are all arranged in the second lamp cavity 30, wherein the diffuser 51, the light guide plate 52 and the reflector are stacked in sequence from the partition 12 to the back plate 3, and the second lamp group 42 is arranged around the outer periphery of the light guide plate 52; preferably, the second lamp group 42 includes two second light strips 421, and the two second light strips 421 are arranged on the two long sides of the rectangular lamp frame 1, and the light-emitting part of the second light strips 421 is arranged toward the light guide plate 52, so as to cooperate with the diffuser 51, the light guide plate 52 and the reflector to simulate the lighting effect of the sky.

[0052] Furthermore, in this embodiment, the outer periphery of the frame 11 is formed with a second flange 14, the second flange 14 extends toward the top of the lamp frame 1, and the protruding end of the second flange 14 is formed with a hook 141. The second flange 14 is provided so that the frame 11 can directly cooperate with the keel of the ceiling (such as aluminum gusset plate ceiling, honeycomb large plate ceiling, etc.) through the second flange 14 and the hook 141 thereon, thereby reducing the difficulty of disassembly and assembly and the installation cost of the clear sky lamp 100; and when the ceiling is an aluminum gusset plate ceiling, the clear sky lamp 100 can also directly replace one or several aluminum gusset plates and be installed on the keel of the ceiling, so that the clear sky lamp 100 can be freely installed in indoor spaces such as kitchens, bathrooms or rooms with aluminum gusset plate ceilings. Preferably, a connecting frame plate 13 is formed between the frame 11 and the second flange 14, and the design of the connecting frame plate 13 allows sufficient assembly space between the keel of the ceiling and the second flange 14, and there is no need to compress the ceiling space. Furthermore, in order to enhance the structural strength of the second flange 14 and the connecting frame plate 13 and ensure the structural reliability of the lamp frame 1 , reinforcing ribs are formed between the second flange 14 , the frame body 11 and the connecting frame plate 13 .

[0053] In summary, it can be seen that by designing the assembly structure of the lamp frame 1 and the optical front frame 2 of the clear sky lamp 100, and fixing the lamp frame 1 and the optical front frame 2 in conjunction with the welding process, it is beneficial to simplify the assembly structure between the lamp frame 1 and the optical front frame 2 and reduce the difficulty of assembly of the two, and can also enhance the three-proof effects of the clear sky lamp 100, so as to better prevent external moisture from entering the second lamp cavity 30 through the assembly gap between the lamp frame 1 and the optical front frame 2, thereby preventing the optical front frame 2 from getting moldy and condensing water droplets, thereby ensuring the luminous effect while extending the service life of the first lamp group 41.

[0054] Clear sky lamp second embodiment

[0055] The difference between this embodiment and the first embodiment of the clear sky lamp lies in the location of the baffle. Specifically, in this embodiment: the baffle is not arranged on the lamp frame, but on the optical front frame.

[0056] As a first alternative solution, the baffle can be integrally formed with the optical front frame by an injection molding process. Among them, the baffle and the optical front frame can be integrally formed by an injection molding process with the following molding methods:

[0057] First, two-color injection molding is used to form between the baffle and the optical front frame, so that the baffle is made of a light-shielding material, while the optical front frame is made of a light-transmitting material.

[0058] Second, a common injection molding process is used to form between the baffle and the optical front frame, and both the baffle and the optical front frame are made of a light-transmitting material; after the baffle and the optical front frame are integrally formed, a light-shielding layer is provided on the baffle, for example, a light-shielding coating is sprayed on the baffle, or a light-shielding material (such as light-shielding paper) is pasted on the baffle.

[0059] As a second alternative solution, the baffle can be detachably connected to the optical front frame. For example, two second slots can be provided on the optical front frame, so that the two second slots correspond to the two baffles one by one. When the baffle is assembled with the optical front frame, the baffle can be inserted into a corresponding second slot.

[0060] Third Embodiment of the Clear Sky Lamp

[0061] Referring to Figure 10 and Figure 11 , the difference between this embodiment and the above-mentioned embodiments is that in this embodiment, no baffle 112 is provided on the lamp frame 1 and the optical front frame 2, and the number of the second light strips 421 included in the second lamp group 42 is equal to the number of sides of the lamp frame 1, and one second light strip 421 is provided inside one side of the lamp frame 1.

[0062] Embodiment of the Lighting System

[0063] The lighting system includes a control terminal and the clear sky lamp described in any one of the first to third embodiments of the clear sky lamp above. The control terminal is electrically connected to the control unit of the clear sky lamp, and / or the control terminal and the control unit perform information interaction. Among them, the control terminal can be a conventional control panel (such as a mechanical switch panel), a smart control panel or a remote control.
