The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
Some embodiments of the present utility model are described in detail below with reference to fig. 1 to 5. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1 and 2, the present embodiment discloses a flat lamp including a bezel 10, a light source, a back plate 60, and a light diffusing member. The frame 10 is mainly used for providing a light source and a light scattering component, and is made of opaque and lightweight materials, such as aluminum, and the frame 10 can be quadrilateral as shown in fig. 1 and 2, circular or other regular shapes.
In order to be able to support the light-diffusing element, a radially inwardly extending support ring 11 is therefore provided on the inner side of one end of the rim 10, the shape of the support ring 11 being adapted to the shape of the rim 10, thereby ensuring the overall quality of the rim 10. The light source is specifically an LED strip, and may be mounted on the inner sides of four sides of the frame 10, for example, by using a heat-conducting double-sided adhesive tape to adhere to the inner side of the frame 10, so that the light incident into the light-diffusing component is distributed more uniformly.
The light diffusing component is arranged in the frame 10 and is contacted with the supporting ring 11, so that the light diffusing component is supported by the supporting ring 11 to prevent the light diffusing component from falling off from the frame 10, meanwhile, the light source is aligned to the light diffusing component, and the light emitted by the light source enters the light diffusing component and is uniformly diffused by the light diffusing component to achieve the effect of uniform light emission.
Referring to fig. 3 and 4, in particular, the light diffusing member includes a light reflecting paper 50, a light guide plate 40, a diffusion film 30, and a plastic plate 20, which are sequentially laminated.
The plastic plate 20 directly contacts the support ring 11 so as to prop up the diffusion film 30, the light guide plate 40 and the reflective paper 50 which are positioned on the plastic plate 20, the plastic plate 20 is a transparent plastic plate 20 with the surface printed with the decorative patterns 21, the decorative patterns 21 have a decorative effect on the whole lamp, the whole appearance of the flat lamp is better, the shape and the size of the decorative patterns 21 are not particularly limited in the embodiment, a user can select and manufacture according to actual demands, thereby meeting the demands of different users on beauty and decoration, and the audience group of the lamp is more.
The light guide plate 40 is made of a material with high reflectivity and no light absorption on a transparent acrylic flat plate, and the side surface of the light guide plate 40 is aligned with the light source so that the light emitted by the light source can be injected into the light guide plate 40, thereby guiding the light to be injected.
Diffusion points, which may be circular, square, or other regular shapes, are screen printed on the surface of the light guide plate 40 facing the light reflecting paper 50 to diffuse light. When the light is incident on the diffusion point, the light is reflected in various directions, and then the total reflection phenomenon generated by the light incident on the upper surface of the light guide plate 40 is destroyed, so that the light can be emitted from the light guide plate 40 toward one surface of the diffusion film 30.
In order to make uniform light emission, various diffusion points with the same density and area size can be utilized to ensure that light is reflected in all directions. For example, the surface of the light guide plate 40 facing the reflective paper 50 is divided into a central area and a peripheral area surrounding the central area, the density of the diffusion points in the central area is greater than that of the diffusion points in the peripheral area, and the area of each diffusion point is the same, because the side surface of the light guide plate 40 is directly aligned with the light source, the light of the peripheral area is more than that of the central area, and therefore the light reflection in the central area can be easier to occur by setting the density of the diffusion points in the central area to be slightly greater, and the probability of light reflection to each reverse reflection is approximately the same, so that the uniformity of the light distribution in the light guide plate 40 is ensured, and the overall light emission of the lamp is more uniform.
Referring to fig. 5, the diffusion film 30 includes a scratch-resistant layer 31, a substrate layer 32, and a diffusion layer sequentially stacked, the scratch-resistant layer 31 facing the light guide plate 40, and the diffusion layer facing the plastic plate 20.
The scratch-proof layer is made of polyurethane acrylic resin, and has a thickness of 0.01-0.03 mm, for example 0.02mm. The material of the base material layer 32 may be selected from polyethylene terephthalate, and the thickness may be 0.1 to 0.3mm, for example, 0.2mm. The diffusion layer may be constituted in particular by uniformly distributed diffusion particles 33. The particle size of the diffusion particles 33 is 20 to 40 μm, and the diffusion particles 33 may be polymethyl methacrylate microspheres.
Thus, the thickness of the diffusion film 30 can be made smaller, and thus the overall thickness of the diffusion module is also smaller, so that the overall thickness of the flat lamp is smaller, and the flat lamp is not particularly abrupt when being fixed on an indoor ceiling, thereby ensuring the overall aesthetic harmony of the indoor. In addition, since the scratch-preventing layer faces the light guide plate 40, it is possible to prevent the light guide plate 40 from being scratched; the diffusion layer faces the plastic plate 20, so that light is emitted from the light guide plate 40 into the scratch-proof layer, passes through the highly transparent substrate layer 32, and is scattered by the diffusion particles 33 to form a uniform surface light source. The diffusion particles 33 are spherical, so that the function of the diffusion particles is similar to that of a convex lens, and light rays are focused to a certain emergent angle when passing through the diffusion particles 33, so that the function of enhancing the emergent light brightness is achieved, and in addition, the fact that the light rays cannot directly penetrate out of the diffusion film 30 is guaranteed due to the fact that the particle sizes of the diffusion particles 33 are different, so that the atomization effect is achieved.
With continued reference to fig. 3 and 4, the reflective paper 50 is a reflective unit made of polyethylene terephthalate film and having a large and uniform distribution, and when light is incident into the reflective paper 50 from the light guide plate 40, the reflective paper 50 can reduce the light loss to a minimum extent by reflecting the light emitted from the side of the light guide plate 40 facing away from the diffusion film 30 into the light guide plate 40, so that the light enters the diffusion film 30, thereby improving the light-emitting efficiency and making the lighting of the lamp brighter.
The back plate 60 is detachably connected to the other end of the frame 10, so that the frame 10 and the back plate 60 together form a closed space for the light diffusing component and the light source to be mounted.
Specifically, the back plate 60 and the frame 10 may be screwed, that is, screws are used to lock the back plate 60 onto the frame 10, so as to realize the detachable connection of the back plate 60 and the frame 10.
A power supply 62 and a hanging plate 61 are also arranged on the side of the back plate 60 facing away from the light scattering component, and the power supply 62 is connected with the light source through a wire so as to supply power to the light source. The hanging plate 61 is mainly used for connecting with a connecting member provided on a building structure such as a ceiling, so that the flat lamp is integrally hung on the ceiling.
When the flat lamp is assembled, the following steps can be performed:
firstly, a light source is adhered to the inner side surface of the frame 10 by using a heat-conducting double-sided adhesive tape, then the plastic plate 20 is placed in the frame 10, one surface of the plastic plate 20 printed with the decorative pattern 21 is contacted with the supporting ring 11, then the diffusion film 30, the light guide plate 40 and the reflective paper 50 are sequentially stacked on the plastic plate 20, finally the back plate 60 is covered on the frame 10, and the back plate 60 and the frame 10 are locked by using screws to complete assembly.
In summary, the utility model discloses a light diffusing component and a flat lamp, wherein the light diffusing component comprises a reflective paper 50, a light guide plate 40, a diffusion film 30 and a plastic plate 20 which are sequentially stacked, the side surface of the light guide plate 40 is used for injecting light emitted by a light source, and the surface of the plastic plate 20 is provided with a decorative pattern 21. Therefore, on the basis of realizing uniform light and soft light, the whole beautiful appearance and decorative effect of the flat lamp can be improved.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
