图1示出了本发明的一实施例中的多面发光的面板灯，该面板灯的多个面均能发光，能够有效地利用光能，增强面板灯的装饰效果。该面板灯包括透明外框1和安装在该透明外框1上的导光组件2。 Fig. 1 shows a multi-faceted panel light in an embodiment of the invention, in which a plurality of faces of the panel lamp can emit light, which can effectively utilize light energy and enhance the decorative effect of the panel lamp. The panel light includes a transparent outer frame 1 and a light guiding assembly 2 mounted on the transparent outer frame 1.
在一些实施例中，该导光组件2包括第一扩散组件3、导光板4、发光光源5和第二扩散组件6。该第一扩散组件3和该第二扩散组件6分别设置在该导光板4相对两表面上，该发光光源5设置在该导光板4的侧面的棱边上，该导光组件2包括至少两个出光面。 In some embodiments, the light guiding assembly 2 includes a first diffusion assembly 3, a light guide plate 4, an illuminating light source 5, and a second diffusion assembly 6. The first diffusing component 3 and the second diffusing component 6 are respectively disposed on opposite surfaces of the light guiding plate 4, and the light emitting source 5 is disposed on an edge of the side of the light guiding plate 4, and the light guiding component 2 includes at least two A shiny surface.
该导光板4为具有一定厚度的光学元件，其形状一般为长方体。发光光源5若直接设置在导光板4的侧面，则发光光源5发出的光经过侧平面上的折射后进入导光板4内，则光的入射角度较小，光的扩散程度的一般。本发明中的发光光源5优选地设置在导光板4的侧面的棱边上，发光光源5发出的光在侧平面上的入射角度变大，使得光经过导光板4后，使得光经过导光板4后往各个角度扩散，且导光组件2具有至少两个出光面，从而该面板灯实现了多个面出光。 The light guide plate 4 is an optical element having a certain thickness and is generally in the shape of a rectangular parallelepiped. When the light source 5 is directly disposed on the side surface of the light guide plate 4, the light emitted from the light source 5 is refracted on the side plane and enters the light guide plate 4. The incident angle of the light is small, and the degree of light diffusion is generally small. The illuminating light source 5 in the present invention is preferably disposed on the edge of the side surface of the light guide plate 4, and the incident angle of the light emitted from the illuminating light source 5 on the side plane becomes large, so that the light passes through the light guide plate 4, so that the light passes through the light guide plate. 4 is diffused to various angles, and the light guiding component 2 has at least two light emitting surfaces, so that the panel light realizes a plurality of surface emitting lights.
进一步地，导光板4的两侧面上具有四条棱边，该四条棱边上均可以设置发光光源5，当该面板灯只是用于简单的照明时，参阅图1，可以只在相对的两条棱边上设置发光光源5。当该面板灯用于装饰效果时，可以在四条棱边上都装上发光光源5，使得面板灯的亮度达到炫目的程度。可以理解地，发光光源5的数量和颜色均可以根据实际的需要进行一定的定制和设计，即只要设置在导光板4的侧面的棱边上的发光光源5的任意组合均在本发明的保护范围内。 Further, the two sides of the light guide plate 4 have four edges, and the four edges can be provided with the light source 5, and when the panel lamp is only used for simple illumination, referring to FIG. 1, only the opposite two can be used. An illuminating light source 5 is arranged on the edge. When the panel light is used for the decorative effect, the illuminating light source 5 can be mounted on the four edges, so that the brightness of the panel light reaches a dazzling level. It can be understood that the number and color of the illuminating light sources 5 can be customized and designed according to actual needs, that is, any combination of the illuminating light sources 5 disposed on the edges of the side surfaces of the light guiding plate 4 is protected by the present invention. Within the scope.
在一些实施例中，该导光板4的各个表面均为出光面。该导光板4靠近该第一扩散组件3的表面为第一出光面，该导光板4靠近该第二扩散组件6的表面为第二出光面。除了第一出光面和第二出光面，该导光板4的四个侧面均为出光面，且该四个侧面被上述的透明外框1所包覆，则光可以透过四个出光面后在透过透明外框1射出，使得发光光源5发出的光得到了进一步地利用，也极大地增强了面板灯的装饰效果。 In some embodiments, each surface of the light guide plate 4 is a light exit surface. The surface of the light guide plate 4 adjacent to the first diffusion unit 3 is a first light-emitting surface, and the surface of the light guide plate 4 adjacent to the second diffusion unit 6 is a second light-emitting surface. Except for the first light-emitting surface and the second light-emitting surface, the four sides of the light guide plate 4 are all light-emitting surfaces, and the four side surfaces are covered by the transparent outer frame 1 , and the light can pass through the four light-emitting surfaces. The light emitted from the illuminating light source 5 is further utilized by the transparent outer frame 1, and the decorative effect of the panel light is greatly enhanced.
该第一扩散组件3包括具有反射和透射双重功能的光学膜片31、以及依序设置在该光学膜片31上的第一扩散层32和至少一个第一棱镜片33。该第一扩散层32为扩散板、扩散膜或由扩散材料涂覆形成在该光学膜片31上的扩散涂层。 The first diffusion assembly 3 includes an optical film 31 having a dual function of reflection and transmission, and a first diffusion layer 32 and at least one first prism sheet 33 sequentially disposed on the optical film 31. The first diffusion layer 32 is a diffusion plate, a diffusion film, or a diffusion coating formed on the optical film 31 by a diffusion material.
该第二扩散组件6包括依序设置在该导光板4上的第二扩散层61和至少一个第二棱镜片62。该第二扩散层61为扩散板、扩散膜或由扩散材料涂覆形成在该导光板4上的扩散涂层。 The second diffusion assembly 6 includes a second diffusion layer 61 and at least one second prism sheet 62 sequentially disposed on the light guide plate 4. The second diffusion layer 61 is a diffusion plate, a diffusion film, or a diffusion coating formed on the light guide plate 4 by a diffusion material.
当导光板4接受来自发光光源5发出的光后，光经过导光板4的第一出光面后再经过光学膜片31，因光学膜片31具有部分光反射的功能，则一部分的光被该光学膜片31反射回导光板4内并经第二出光面射出。从第二出光面射出的一部分光经过第二扩散层61做光的均匀扩散后，再经过第二棱镜片62予以有效的聚光，而能在第二出光面上顺利的输出光源。又，同样来自于发光光源5发出的光，除了从第二出光面射出的一部分光外，另一部分光经过导光板4的第一出光面后再经过光学膜片31，因光学膜片31具有部分光透射的功能，则另一部分光会透射过该光学膜片31后射出。从光学膜片31射出的另一部分光会经过第一扩散层32做光的均匀扩散后，再经过第一棱镜片33予以有效的聚光后，而能在第一出光面上顺利的输出光源。 After the light guide plate 4 receives the light emitted from the light source 5, the light passes through the first light exit surface of the light guide plate 4 and then passes through the optical film 31. Since the optical film 31 has a partial light reflection function, a part of the light is The optical film 31 is reflected back into the light guide plate 4 and emitted through the second light exit surface. A part of the light emitted from the second light-emitting surface is uniformly diffused by the second diffusion layer 61, and then efficiently concentrated by the second prism sheet 62, so that the light source can be smoothly outputted on the second light-emitting surface. Further, the light emitted from the illuminating light source 5, in addition to a part of the light emitted from the second illuminating surface, passes through the first illuminating surface of the light guide plate 4 and then passes through the optical film 31, since the optical film 31 has Part of the light transmission function, another part of the light will be transmitted through the optical film 31 and then emitted. The other part of the light emitted from the optical film 31 is uniformly diffused by the first diffusion layer 32, and then effectively concentrated by the first prism sheet 33, and the light source can be smoothly outputted on the first light-emitting surface. .
在一些实施例中，该透明外框1内侧具有卡槽，该导光组件2以其四周边缘与该卡槽配合安装在该透明外框1上。该透明外框1的形状对应导光组件2的形状设置，可为回型框架。可以理解地，该透明外框1的材质可以采用常见的透光材料，例如，亚克力、PC材料或玻璃等。 In some embodiments, the inner side of the transparent outer frame 1 has a card slot, and the light guiding component 2 is mounted on the transparent outer frame 1 with its peripheral edge and the card slot. The shape of the transparent outer frame 1 corresponds to the shape of the light guide assembly 2, and may be a return frame. It can be understood that the material of the transparent outer frame 1 can adopt a common light transmissive material, for example, acrylic, PC material or glass.
进一步地，该卡槽内设置有安装座，该发光光源5安装在该安装座上。可以理解地，还可以采用其他的固定方式将该发光光源5安装在卡槽内，例如贴装或卡接等。 Further, a mounting seat is disposed in the card slot, and the illuminating light source 5 is mounted on the mounting seat. It can be understood that the illuminating light source 5 can also be installed in the card slot by other fixing methods, such as mounting or snapping.
更进一步地，该发光光源5包括灯板及设置在该灯板上的数个LED灯。该灯板的形状呈长条状，其长度可以与导光板4的宽度相适配，从而可以得到最好的发光效果。当然设置发光光源5的方式有很多种，例如该该发光光源5还可包括条状的LED灯带以及设置在该LED灯带上的数个LED灯。采用LED灯带的好处在于，将LED灯带作为发光光源5时，产生的热量较小，能延长该面板灯的使用寿命。且将LED灯带作为发光光源5时，若LED灯带与上述的导光组件2一体成型，使得该面板灯的结构更加的紧凑。 Further, the illuminating light source 5 includes a light board and a plurality of LED lights disposed on the light board. The shape of the lamp plate is elongated, and its length can be adapted to the width of the light guide plate 4, so that the best illuminating effect can be obtained. Of course, there are many ways to set the illuminating light source 5. For example, the illuminating light source 5 may further include a strip of LED strips and a plurality of LED lamps disposed on the strip of LED strips. The advantage of using the LED strip is that when the LED strip is used as the illuminating source 5, the amount of heat generated is small, which can extend the life of the panel lamp. When the LED light strip is used as the light source 5, if the LED strip is integrally formed with the above-described light guide unit 2, the structure of the panel lamp is more compact.
综上，该面板灯实现了多个面发光，增加了光照角度，达到了360°，从而大大地提高了光能利用率，满足了节能环保的趋势。 In summary, the panel light realizes multiple surface illumination, increasing the illumination angle to 360°, thereby greatly improving the utilization of light energy and meeting the trend of energy conservation and environmental protection.
