Description

Technical Field

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

[0002] In some closed and / or poorly lit places (such as rooms without windows, offices, kitchens, bathrooms, subway stations, hospital wards, etc.), although there are lamps to illuminate them, the lighting effects of ordinary lamps are monotonous and rigid, which makes people who stay in such places for a long time easily feel depressed; in response to this, a new type of lamp is currently launched on the market - blue sky lamp (or sky lamp, blue sky lamp), which can simulate the effect of clear sky and sunlight slanting into the window, giving people a feeling of being in a sunny natural environment, thereby improving the sensory comfort of people in closed and / or poorly lit places, and alleviating people's depression, irritability and other negative emotions.

[0003] like Figure 1 As shown, an existing blue sky lamp 9 includes a fixing frame 91, a surface frame 92, a back plate 93, an optical frame 94, a light guide plate (Rayleigh scattering 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 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 optical frame 94 is connected to the fixed frame 91 and is arranged near the bottom of the fixed frame 91, and a second lamp cavity is formed between the optical 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, and 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 facing 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 optical frame 94 to simulate the effect of sunlight shining obliquely into the window.

[0004] In order to simulate the effect of sunlight shining obliquely into the window, it is necessary to form a light-transmitting area and a light-shielding area on the optical frame 94, and there are three existing methods:

[0005] The first method is to paste opaque material (such as shading paper) on the portion of the optical frame 94 corresponding to the portion where the shading area is to be formed. However, this method has the disadvantages of complicated operation and low production efficiency, and the glue used to paste the opaque material is prone to excessive pollutants (such as formaldehyde).

[0006] The second method is to spray an opaque paint layer on the portion of the optical frame 94 corresponding to the light-shielding area. However, this method also has the disadvantages of complicated operation and low production efficiency. If the opaque paint layer is not environmentally friendly, it is also easy to cause excessive pollutants (such as formaldehyde).

[0007] The third method is to mold the optical frame 94 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 optical frame 94. However, both of these processing methods have disadvantages such as high production cost and difficulty in production. Summary of the invention

[0022] As can be seen from the above, the design of the second inclined portion is conducive to better simulating the effect of sunlight obliquely shining into the window; the third overlapping portion is used to cooperate with the partition to prevent the light in the first lamp cavity from penetrating into the second lamp cavity, so as to ensure the lighting effect of the second lamp group in the second lamp cavity, thereby ensuring the lighting effect of the blue sky lamp; and the fourth overlapping portion is used to cooperate with the frame to prevent the light in the second lamp cavity from penetrating into the blue sky lamp through the gap between the optical frame and the frame, so as to ensure the lighting effect of the blue sky lamp.

When the cover plate 2 is assembled with the lamp frame 1, the second locking member 109 passes through the second through hole 21 and is fixedly connected with the second connecting hole 111, so as to fix the cover plate 2 on the lamp frame 1. The partition 12 is used to support the reflective layer 102, the light guide plate 103, the diffuser 104 and the first lamp group 105 etc. arranged in the first lamp cavity 20, and the partition 12 is also used to shield the light emitted by the first lamp group 105, so as to prevent the light emitted by the first lamp group 105 from entering the second lamp cavity 40 and interfering with the second lamp group 106 arranged in the second lamp cavity 40, thereby ensuring the lighting effect of the blue sky lamp 100. In addition, the provision of the partition 12 is also conducive to the design of the inclination angle of the light emitting surface (i.e., the second inclined portion 41 described below) of the optical frame 4, and optimizes the overall structure of the lamp housing unit 101.

[0045] Combination Figures 6 to 8 The decorative frame 3 is made of a shading material through an injection molding process. The decorative frame 3 is made of a shading material so that the decorative frame 3 is not penetrated by light and forms a shading area, thereby cooperating with the optical frame 4 and the second lamp group 106 so that the blue sky lamp 100 can create an excellent effect of sunlight shining obliquely into the window. Among them, the shading material is preferably a PC (polycarbonate) material with shading performance; of course, as other optional solutions, 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 will not be explained in detail here.

[0046] Preferably, the decorative frame 3 has a first inclined portion 31, a first overlap portion 32 and a second overlap portion 33.

[0047] Preferably, a first clamping structure may be provided on the frame 11, and a second clamping structure matching the first clamping structure may be provided on the second overlap portion 33. When the decorative frame 3 is assembled with the lamp frame 1, the second clamping structure on the decorative frame 3 is firstly engaged with the first clamping structure on the lamp frame 1, so that the decorative frame 3 is initially fixed on the lamp frame 1 before the decorative frame 3 and the lamp frame 1 are welded, and the decorative frame 3 and the lamp frame 1 are kept in a correct assembly position; then, the first welding wire 321 is welded to the partition 12, and the second welding wire 331 is welded to the frame 11, so that the decorative frame 3 is reliably fixed on the lamp frame 1.

[0048] The optical frame 4 is made of a translucent material or a semi-translucent material through an injection molding process. The translucent material or the semi-translucent material is used to make the optical frame 4, so that the light emitted by the second lamp group 106 in the second lamp cavity 40 can penetrate the optical frame 4, and the optical frame 4 forms a translucent area, so that the blue sky lamp 100 can create an excellent effect of sunlight obliquely shining into the window in cooperation with the decorative frame 3 and the second lamp group 106.

When the optical frame 4 is assembled, the protrusion 44 on itself is inserted into a corresponding slot 340. This design is conducive to ensuring the flatness of the decorative frame 3 and the optical frame 4 after assembly and splicing, and the stopper 34 and the protrusion 44 can further prevent the light in the second lamp cavity 40 from penetrating the decorative frame 3, thereby ensuring the effect of simulating sunlight obliquely shining into the window of the blue sky lamp 100 equipped with the lamp housing unit 101.

Among them, the design of the second inclined portion 41 is conducive to better simulating the effect of sunlight obliquely shining into the window; the third overlapping portion 42 is used to cooperate with the partition 12 to prevent the light in the first lamp cavity 20 from penetrating into the second lamp cavity 40, so as to ensure the lighting effect of the second lamp group 106 in the second lamp cavity 40, thereby ensuring the lighting effect of the blue sky lamp 100; and the fourth overlapping portion 43 is used to cooperate with the frame 11 to prevent the light in the second lamp cavity 40 from penetrating into the blue sky lamp 100 through the gap between the optical frame 4 and the frame 11, so as to ensure the lighting effect of the blue sky lamp 100.

[0052] Preferably, the frame body 11 is provided with a third engaging structure 112, and the fourth overlapping portion 43 is provided with a fourth engaging structure 431 that cooperates with the third engaging structure 112; when the optical frame 4 is assembled with the light frame 1, the protrusion 44 on the optical frame 4 is inserted into a correspondingly arranged slot 340, and the optical frame 4 is pressed toward the frame body 11, so that the frame body 11 is sleeved on the optical frame 4. At this time, the third overlapping portion 42 of the optical frame 4 overlaps the protruding end of the partition 12 of the light frame 1, and the fourth engaging structure 431 on the fourth overlapping portion 43 of the optical frame 4 is engaged and connected with the third engaging structure 112 on the frame body 11 of the light frame 1, so that the optical frame 4 is assembled on the light frame 1. In this embodiment, the third engaging structure 112 is a slot, and the fourth engaging structure 431 is a buckle.

[0053] Furthermore, the partition plate 12 of the lamp frame 1 is provided with a first through hole 121, and the second inclined portion 41 and / or the third overlapping portion 42 of the optical frame 4 are provided with a first connecting hole 411; when the optical frame 4 is assembled with the lamp frame 1, the first locking member 108 passes through the first through hole 121 and is connected to the first connecting hole 411, thereby further fixing the optical frame 4 and the lamp frame 1 to prevent the optical frame 4 from shaking relative to the lamp frame 1. Of course, in other embodiments, only the design of the first through hole 121 on the partition plate 12 and the first connecting hole 411 on the second inclined portion 41 and / or the third overlapping portion 42 may be retained.

[0054] 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 20, and the diffuser plate 104, the light guide plate 103 and the reflective layer 102 are stacked in sequence from the partition plate 12 to the cover plate 2. 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 lamp frame 1, and the first light strips 1051 extend along the length direction of the lamp frame 1. Among them, the first light strip 1051 can be fixed to the lamp frame 1 by adhesive bonding.
