背景技术Background technique

目前市场上的LED装饰灯，多是将LED灯泡设置在下面直接发光，这种LED装饰灯需要较多数目的LED灯泡来达到光面亮度均匀的效果，耗能大，生产成本高。现在，也有通过采用将LED灯泡设置在导光板周围的侧面的凹槽内，形成一种提供面光的LED装饰灯，但该种装饰灯只是单面发光，立体感差，装饰效果较差，特别对于转角处使用的LED装饰灯更是一片空白。At present, LED decorative lights on the market mostly use LED bulbs to directly illuminate underneath. Such LED decorative lamps require a larger number of LED bulbs to achieve uniform brightness of the smooth surface, high energy consumption and high production cost. Now, there is also an LED decorative lamp that provides a surface light by adopting a recess in which the LED bulb is disposed on the side around the light guide plate, but the decorative light is only one-sided illumination, the stereoscopic effect is poor, and the decorative effect is poor. Especially for the LED decorative lights used at the corners is a blank.

发明内容Summary of the invention

本发明目的是提供一种专用于室内转角，两块发光板不但同时发出不同色彩的光，而且两面发光的转角式LED带孔双发光板装饰灯。The object of the present invention is to provide a corner-shaped LED perforated double-emitting panel decorative lamp which is dedicated to indoor corners and which emits light of different colors at the same time, and which is illuminated on both sides.

为实现上述目的，本发明采用的技术方案是：一种转角式LED带孔双发光板装饰灯由条形灯座、两块导光板、线路板和LED灯组成，所述导光板是由透明板和设在透明板表面上的具有反射、折射作用的网状凹凸点组成，在灯座设有出光槽，两出光槽之间呈30～150度间任一角度，在出光槽两侧设有引光板，所述两块导光板分别固定在灯座的引光板上，线路板设在灯座内，所述LED灯固定线路板上，LED灯与出光槽相对应。In order to achieve the above object, the technical solution adopted by the present invention is: a corner type LED perforated double illuminating panel decorative lamp is composed of a strip lamp holder, two light guide plates, a circuit board and an LED lamp, and the light guide plate is transparent The plate is composed of a mesh-shaped concave-convex point having a reflection and refraction function on the surface of the transparent plate, and the light-slot groove is arranged in the lamp holder, and the two light-emitting grooves are at any angle between 30 and 150 degrees, and are arranged on both sides of the light-emitting groove. There is a light guide plate, the two light guide plates are respectively fixed on the light guide plate of the lamp socket, the circuit board is disposed in the lamp socket, and the LED lamp is fixed on the circuit board, and the LED lamp corresponds to the light exit slot.

所述导光板的双面设置有网状凹凸点或丝印。The double-sided surface of the light guide plate is provided with a mesh-like concave-convex dot or a silk screen.

所述导光板上设有多个通孔。The light guide plate is provided with a plurality of through holes.

所述导光板的厚度边表面和通孔的内表面为磨沙面。The thickness side surface of the light guide plate and the inner surface of the through hole are frosted surfaces.

所述引光板与灯座一体成型。The light guide plate is integrally formed with the lamp holder.

所述网状凹凸点由导光油墨点构成。The mesh-like irregularities are composed of light guiding ink dots.

所述网状凹凸点是磨沙后的凹凸。The mesh-shaped uneven spots are irregularities after sanding.

本发明采用上述结构后，通过在灯座上设置呈90度分布的两个出光槽，并在出光槽上设置导光板，同时灯座内的LED灯投光方向朝向导光板，在出光槽两侧延伸有引光板，因此通过引光板可使LED灯的光集中向导光板方向投射，再经导光板两侧面射出，形成了两面发光的发光板，并且两组导光板由不同的LED灯组对其进行照射，同一时刻两组的LED灯可发出不同的颜色，因此，两块发光板可提供两种不同色彩的光效果；两导光板之间呈30～150度间任一角度度，适用于室内、室外转角处安装使用；进一步的改进通过在导光板上设置通孔，可增大导光板出光面的光通量，既可减少风阻，又可形成特殊的光效果；且导光板是通过出光槽两侧的引光板固定，安装牢固。是导光板的厚度边表面和通孔的内表面为磨沙面，使得发光板边沿和通孔的光线更柔和，更加美观。在两导光板之间设置LED发光带，在一柔和大光面上增加一条亮丽的光带，可达到另一种不同的装饰效果。本发明广泛适于道路防护栏、室内、室外等转角处装饰使用。After adopting the above structure, the present invention provides two light-emitting grooves distributed at 90 degrees on the lamp holder, and a light guide plate is disposed on the light-emitting groove, and the LED light in the lamp holder is projected toward the light guide plate in the light-emitting groove. The light guide plate is extended on the side, so that the light of the LED lamp can be projected by the light guide plate in the direction of the light guide plate, and then emitted through the two sides of the light guide plate to form a light-emitting plate with two sides of the light-emitting plate, and the two sets of light-guiding plates are paired by different LED light groups. The illumination is performed at the same time, and the two sets of LED lights can emit different colors at the same time. Therefore, the two illuminating plates can provide two different color light effects; the two light guide plates can be at any angle between 30 and 150 degrees, suitable for It is installed at indoor and outdoor corners; further improvement can increase the luminous flux of the light-emitting surface of the light guide plate by providing through holes on the light guide plate, which can reduce wind resistance and form special light effect; and the light guide plate passes through the light-emitting plate. The light guide plates on both sides of the slot are fixed and installed firmly. The thickness side surface of the light guide plate and the inner surface of the through hole are frosted surfaces, so that the light of the edge of the light emitting plate and the through hole are softer and more beautiful. An LED light strip is arranged between the two light guide plates, and a bright light strip is added on a soft and large light surface to achieve another different decorative effect. The invention is widely applied to the decoration of corners of road fences, indoors and outdoors.
