DETAILED DESCRIPTION
[0036] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0037] The utility model is further described below in conjunction with embodiments.
[0038] Example:
[0039] The utility model provides an ultra-thin blue sky lamp. The product of this solution is different from the blue sky lamp structure and principle of the prior art using Rayleigh scattering. This product uses a light-transmitting component 20 with a light guide plate 23 and a blue light-transmitting sheet 24 as the core, and utilizes the filtering and light-transmitting capabilities of the blue light-transmitting sheet 24, as well as the uniform and reflective effects of the light guide plate 23 and the reflective sheet 40 on light, so that the product presents a "blue sky" luminous effect, just like a skylight on the roof, which is similar to the visual effect of the blue sky lamp in the prior art. While presenting a similar visual effect, this product greatly reduces the thickness of the blue sky lamp, so that the blue sky lamp can better adapt to different use and installation environments.
[0040] The main structure of this product is described below:
[0041] Reference Figure 1-6 The blue sky lamp of this product mainly includes a lamp frame 10 for supporting and protecting, a light-transmitting component 20 and an LED light strip 30 for emitting light. An open receiving groove 11 is formed inside the lamp frame 10, and a light-transmitting hole 12 communicating with the receiving groove 11 is arranged on the corresponding side; wherein, a bottom cover 50 is encapsulated at the opening of the receiving groove 11.
[0042] The main body of the light-transmitting component 20 is placed in the receiving groove 11 and covers the light-transmitting hole 12. The LED light bar 30 using white light surrounds the outside of the light-transmitting component 20. The light-transmitting component 20 is stacked with a protective plate 21, a light guide plate 23 and a blue light-transmitting sheet 24 in sequence from one side of the light-transmitting hole 12. The lamp beads 31 of the LED light bar 30 face and are close to the side of the light guide plate 23. In this embodiment, the light guide plate 23 is an acrylic plate, and its front and back sides are etched with laser dots. A reflective sheet 40 is attached to the top of the blue light-transmitting sheet 24. The light emitted by the LED light bar 30 penetrates through the side of the light guide plate 23 to the middle. The light in the path is transmitted on the upper and lower sides of the light guide plate 23 through the laser dots etched on the front and back. The light toward the upper side passes through the blue light-transmitting sheet 24, and then is reflected downward by the reflective sheet 40. The blue light-transmitting sheet 24 that passes the light presents a "transparent" sky blue color, and the visual effect is more realistic.
[0043] In this embodiment, the blue light-transmitting sheet 24 is made of a blue soft film made of PVC material, and adopts the standard sky blue RGB color number: R: 135, G: 206, B: 235. Preferably, the light-transmitting component 20 also includes a diffuser 22 for uniform light, and the diffuser 22 is laid between the protective plate 21 and the light guide plate 23. The diffuser 22 of PP frosted material can be optionally installed to uniform soft light.
[0044] The blue sky lamp of this solution adopts a light-transmitting component 20 with a light guide plate 23 and a blue light-transmitting sheet 24 as the core, and a structural design in which an LED light bar 30 as a light source is installed on the outside of the light-transmitting component 20, based on the simulation of the "blue sky" luminous effect. The structural composition of this product makes the thickness of the lamp body only 25mm, which greatly reduces the thickness of the blue sky lamp compared with the existing technology. It can be installed in low-rise high-rise houses and embedded in low-height ceilings, which is easy to use and install. It greatly improves the application scenarios of the blue sky lamp with "blue sky" effect.
[0045] The following is the preferred implementation method of the ultra-thin size of this product:
[0046] Reference Figure 7-10 In this embodiment, the shape of the lamp frame 10 is circular, and the corresponding bottom cover 50, light-transmitting hole 12 and light-transmitting component 20 are similar in shape to the lamp frame 10. Of course, the lamp frame 10 can also be oval, rectangular or other polygonal in appearance.
[0047] The first rib 13 and the second rib 14 are fixed at intervals on the inner side of the accommodating groove 11. The first rib 13 and the second rib 14 are located at the outer circle of the light-transmitting hole 12, and an annular guide groove 15 is formed between the first rib 13 and the second rib 14. During assembly, one side of the LED light bar 30 is inserted and embedded in the guide groove 15, and the main body is laid along the guide groove 15 to form a circular ring, so as to realize the surrounding installation outside the light-transmitting component 20. At the same time, in order to improve the stability of the LED light bar 30 in the guide groove 15, a T-shaped boss 16 is fixed on the guide groove 15, and the two sides of the T-shaped boss 16 and the second rib 14 form a limiting groove 17. During installation, the head and tail ends of the LED light bar 30 are respectively correspondingly stuck in the limiting groove 17. By limiting the head and tail, it can effectively prevent the LED from falling out of the guide groove 15 and the occurrence of end misalignment and crossing.
[0048] Preferably, the first rib 13 is designed to be located on the outside of the light-transmitting component 20, and the second rib 14 is designed to be located on the outside of the first rib 13, and the height of the second rib 14 is greater than the height of the first rib 13. The shorter first rib 13 can avoid blocking the light of the LED light strip 30, and the taller second rib 14 not only provides limiting support for the bent and deformed LED light strip 30, but also serves as a matching rib position on one side of the connecting column 18 on the lamp frame 10 to maintain the reliability of the connecting column 18.
[0049] In addition, in the design of fixing the reflective sheet 40 and the light-transmitting component 20 at the light-transmitting hole 12, a third rib 51 is fixed through the inner side of the bottom cover 50. The third rib 51 is composed of two ring ribs and radial connecting ribs. In the overall rib height design, when the bottom cover 50 is encapsulated on the light frame 10, the end face of the third rib 51 contacts the reflective sheet 40 and presses and fixes the light-transmitting component 20. The design of the third rib 51 not only strengthens the strength of the bottom plate, but also can well fix the reflective sheet 40 and the light-transmitting component 20 on the inside. At the same time, a mounting groove 54 is formed by eliminating part of the rib position inside the third rib 51. The mounting groove 54 is used to fix the driver of the LED light bar 30, which solves the problem of the extra height space occupied by the driver and further ensures the ultra-thin product appearance.
[0050] A plurality of connection holes 52 are evenly arranged on the outer circle of the bottom cover 50, and the lamp frame 10 is fixed with connection columns 18 matching the connection holes 52, which are fastened by screws during packaging; in addition, convex stoppers 53 are arranged between the connection holes 52, and both ends of the convex stoppers 53 are extended to connect with the third rib 51, and the convex stoppers 53 can effectively keep the outer circle of the bottom cover 50 aligned with the edge of the lamp frame 10, and at the same time, improve the strength of the outer circle of the bottom cover 50 to a certain extent.
[0051] In the design for realizing quick surface installation of the lamp, a groove 55 is formed in the middle of the bottom cover 50 in the direction of the protrusion of the third rib 51, and a connecting seat 56 is movably snap-connected in the groove 55. The connecting seat 56 is embedded in the groove 55, and there are oblong holes on the connecting seat 56 for installation. In surface installation, the connecting seat 56 is first fixed to the top of the wall, and then the lamp body is installed on the connecting seat 56 by rotating the buckle.
[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
