Description

Technical Field

[0001] The utility model belongs to the technical field of lighting fixtures, and in particular relates to a light emitting structure with vertical light emission and adjustable angle. Background Art

[0002] In the existing lamp design, the light emitting surface of the general lamp is horizontal. This light emitting method is to arrange the light source on the horizontal plane of the chassis, and the light emitted by the light source is mixed in the light source cavity, and then transmitted through the horizontally arranged optical plate after light diffusion, and finally illuminate the work surface below the lamp. The lighting effect created by this traditional light emitting method is relatively simple, which is only to meet the basic lighting needs of the work surface below, and cannot provide more creative and visually beautiful light and shadow effects. Traditional horizontal light emitting lamps are difficult to create special light and shadow atmospheres in some scenes with high requirements for atmosphere creation, such as high-end hotel lobbies, art exhibition halls, landscape lighting and other occasions.

[0003] In addition, most of the traditional lamps that use horizontal light source layout have the following disadvantages:

[0004] 1. The light effect is single, and the light direction is limited to vertical downward, making it difficult to form a three-dimensional light environment;

[0005] 2. Poor scene adaptability, unable to simulate the spatial layering of natural light scenes;

[0006] 3. The visual experience is limited. The light environment lacks lateral extension and cannot create special light and shadow effects such as the skyline.

[0007] Therefore, it is necessary to provide a light-emitting structure to solve the technical defects of the existing lamps, such as the single scene lighting effect and the lack of expression of the natural light environment, caused by the unidirectional vertical light emission. Utility Model Content

[0008] In view of the problems existing in the prior art, the purpose of the present invention is to provide a light emitting structure with vertical light emission and adjustable angle.

[0009] In order to solve the above problems, the utility model adopts the following technical solutions:

[0020] Beneficial effects of the utility model

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] 1. Through the design and improvement of the structure, the utility model allows the light emitted by the flexible light source board to be divided into two parts. One is direct light, which is refracted toward the center of the light-transmitting plate after passing through the light-transmitting ring or the light-transmitting plate, and the other is reflected light, which is reflected by the reflective plate and then emitted to the light-transmitting ring, and then refracted twice by the light-transmitting ring, and then refracted toward the center of the light-transmitting plate. The two kinds of light will form a uniform circumferential vertical light in the light-transmitting ring, and the light of the light source board will be mixed. With the light output of the multi-color lamp beads, a continuous gradient color of 1800K to 12000K can be achieved;

[0024] 3. The utility model designs a three-dimensional light path reconstruction, that is, the secondary optical conversion from horizontal light source to vertical light output, and the gradient light mixing structure of the transparent circle, which can make transition control based on the color temperature of the CIE1931 chromaticity diagram, and the whole can be modularly assembled to achieve seamless splicing and expansion. It has excellent visual effects, is simple and beautiful as a whole, is easy to assemble and disassemble, and is energy-saving.

[0035] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0036] like Figures 1 to 11 As shown, the utility model is a vertical light emitting structure with adjustable angle, which is mainly composed of a chassis component 1, a flexible light source board 2, a light source board 3, a light transmission board 4, a light transmission ring 5, a cotton strip 6, a reflective plate 7 and a shell 8, and the overall assembly structure is as follows:

[0037] The chassis assembly 1 and the shell 8 are provided with screw holes at relative positions for connection and assembly by screws; the inner side of the shell 8 is designed and integrally formed with a card slot, an auxiliary upper edge 80, a convex edge 81 and a convex rib 82; there are three card slots, namely a first card slot 83, a second card slot 84 and a third card slot 85, and the three card slots correspond to three different light output angles. The flexible light source board 2 is fixed to the working position by being clamped in one of the card slots and attached to the auxiliary upper edge 80. For details, please refer to Fig.11 , Fig.11 The three normal lines in correspond to the reference angles of the flexible light source board 2 in the three slots, respectively. Fig.11 Each flexible light source board 2 has a pair of light schematic lines, and the angle between each pair of light schematic lines is the maximum light output angle of the flexible light source board 2 when it is located in the slot position. The corresponding figures can be referred to Fig.12 , Fig.13 and Fig.14, corresponding to the first card slot 83, the second card slot 84 and the third card slot 85 respectively, so the flexible light source board 2 can be assembled in different card slots to obtain different emission angles and light path emission angles, and the size of the angle is the range of the light path, and then different effects can be obtained by cooperating with the light-transmitting circle 5; the convex edge 81 supports the light-transmitting circle 5 to set it in the shell 8; the convex rib 82 is used for positioning the reflector 7 and the cotton strip 6 to position and install both on the inner side of the shell 8; the light source board 3 is fixed at the bottom of the chassis assembly 1 to cooperate with the flexible light source board 2; the lengths of the reflector 7 and the cotton strip 6 must be the same as the length of the flexible light source board 2, and the reflector 7 and the cotton strip 6 can form a 360-degree ring, which is nested in the cavity between the shell 8 and the light-transmitting circle 5, wherein the reflector 7 is arranged below the flexible light source board 2 in the shell 8; the assembly between the chassis assembly 1 and the shell 8 is provided with a sealing ring.

[0038] The research and development purpose of this utility model is to provide a light-emitting structure perpendicular to the circumference of the light-emitting surface, and to change the light-emitting direction of the flexible light source plate 2 through the self-researched optical design, so as to superimpose the light of the light source arranged on the outer circle of the horizontal plane of the chassis component 1 in the vertical direction around the light source surface, so as to create natural light scenes such as the sea and sky at the interface between the sea level and the sky or the light and shadow of the horizon at the interface between the distant lake surface and the sky based on multi-color LED lamp beads, so as to meet the needs of creating light and shadow atmosphere in special scenes and enrich the lighting effect. Therefore, the key technology of this utility model is located in the shell 8, and the components arranged in the shell 8.

[0039] Embodiment 1 is based on the shell 8 being a perfect circle. Based on the perfect circle shape of the shell 8, the flexible light source board 2, the reflector 7 and the cotton strip 6 need to be assembled close to the inner side of the shell, so they are all semicircular and bent in the shell 8. The flexible light source board 2 can be selectively installed in three assembly positions. For details, please refer to Fig.11The light effect emitted from each installation position is different, which is specifically due to the refraction angle of the multi-color LED lamp beads and the reflector 7. The light emission angles of the three card slots are between 40° and 60°, and the light emission angles are different from each other. For example, the first card slot 83 can be 40°, the second card slot 84 can be 50°, and the third card slot 85 can be 60°. It should be further explained that the reflective plate 7 is arranged below the flexible light source plate 2 in the shell 8, and the cotton strip 6 is arranged symmetrically with the reflective plate 7 in the shell 8. It is on the same installation horizontal line as the reflective plate 7, and the reflective plate 7 and the cotton strip 6 are each designed with a semi-circular arc structure, which is symmetrically assembled in the shell 8 to form a 360-degree ring, that is, the reflective plate 7, the cotton strip 6 and the flexible light source plate 2 are all arranged with a semi-circular arc length of 180° in the shell 8. The function of the cotton strip 6 is not only to seal and dustproof, and fill and fix, but more importantly, it can prevent light leakage, and prevent the light refracted in the opposite direction from leaking through the shell 8, or refracting again to affect the light output effect.

[0040] As for the reflector 7, it has been designed after many studies, and its overall structure is an arc-shaped structure, that is, its cross section is an arc-shaped, so that the light effect emitted by the flexible light source board 2 can be refracted along a predetermined route, and an ideal light effect can be obtained. It is worth explaining that the reflector 7 can be eliminated and the same light effect can be obtained, but the premise is that the inner side wall 86 of the shell 8 can be designed and formed into an arc-shaped structure, so that on the basis of the same curvature, a high-reflection aluminum film is added, which can save the setting of the reflector 7 and its cost, but still obtain the same effect.

[0041] As for the light-transmitting circle 5 , its cross section is in the shape of a right-angled triangle, and its thickness gradually increases from bottom to top. Such a design is designed and formed to match the first reflection path of the reflection plate 7 .

[0042] Embodiment 2: The light-transmitting ring 5 may further form a stepped surface 50 at its top, and the stepped surface 50 may support and position the light-transmitting plate 4, eliminating the need for other fasteners for assembly and fixation.

[0043] The chassis assembly 1 of the utility model includes a drive and remote control module, which can adjust and control the flexible light source board 2 and the light source board 3 provided with multi-color lamp beads. Through the pre-recorded intelligent algorithm control, the color temperature of the whole lamp 1800K~12000K can be accurately adjusted within Duv<0.002, and in the 2700K-8000K color temperature range, Duv<0.001, and the color can accurately fall on the Planck black body line. After the overall assembly of the utility model is completed, the flexible light source board 2 and the light source board 3 need to be debugged, and the luminous intensity and color temperature of the light source are adjusted through remote control drive, and the light output effect of the light output module in the circle perpendicular to the horizontal light-emitting surface is observed.

[0044] After testing, the utility model has a peripheral light output efficiency of 68-70lm / W, while the traditional solution is only 50lm / W, and it saves more than 15% energy than the traditional solution. The vertical light output uniformity has also reached 0.85 compared with the 0.70 of the traditional solution, and the color temperature transition smoothness is Δuv<0.003. It can achieve a variety of natural light effects based on multi-color, such as orange sunset, pink sunset, blue and white light scenes, etc. Gradient or multi-color effects, and its mixed light distance is shortened to 25mm compared to 35mm or more of the traditional solution.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
