Description

说 明 书 带有图形的导光板 技术领域  Description Book with a light guide plate
本发明涉及光线传导装置， 尤其涉及一种可广泛应用于商用及家用的实 用照明及装饰照明灯具、 装饰品、 工艺品、 出路牌、 导向灯、 广告灯箱等方 面的导光板。 背景技术  The present invention relates to a light-conducting device, and more particularly to a light guide plate which can be widely applied to commercial and domestic practical lighting and decorative lighting fixtures, decorations, handicrafts, exit signs, guide lamps, advertising light boxes and the like. Background technique
导光板设计原理源于笔记本电脑的液晶显示屏。 导光板利用荧光灯、 The design principle of the light guide plate is derived from the liquid crystal display of the notebook computer. The light guide plate uses fluorescent lamps,
CCFL、 LED光源透过按光学原理计算后的导光点或导光槽， 在反光膜（反射 板）和扩散膜作用下， 将线光源或点光源转变为面光源。 为使导光板能均匀 发光， 必须通过各种疏密、 大小不一的导光点， 以保证光线往各个方向反射 的效率基本相同。 反射片 （反射板） 的用途在于将导光板底面透露出的光线 反射回导光板中， 用来提高光的使用效率， 提高亮度。 扩散膜的作用在于使 光更均匀更柔和。 导光板的应用范围很广， 如电视机背光源、 照明、 装饰、 广告、 指示标示牌等等。 现有的导光板的网点设计都是满版布点， 单调无变 化， 外形也变化不大。 发明内容 The CCFL and the LED light source convert the line light source or the point light source into a surface light source through the light guiding point or the light guiding groove calculated by the optical principle, under the action of the reflective film (reflecting plate) and the diffusion film. In order to make the light guide plate emit light uniformly, it is necessary to pass various light-tight and different-sized light guiding points to ensure that the light is reflected in all directions with the same efficiency. The purpose of the reflective sheet (reflector) is to reflect the light emitted from the bottom surface of the light guide back into the light guide plate to improve the efficiency of light use and increase the brightness. The role of the diffuser film is to make the light more uniform and softer. Light guides are used in a wide range of applications, such as TV backlights, lighting, decoration, advertising, signage, and more. The dot design of the existing light guide plate is full layout, monotonous and non-variable, and the shape does not change much. Summary of the invention

The portion where the light guiding point is provided is a light emitting region, and the hollow portion is a non-light emitting region. When various light sources are input to the light guide plate, after the light is incident, the light-emitting pattern is formed by the reflection of the light-guiding point, and the light-conducting point portion is guided by the light to refract light, and the hollow portion is a non-light-emitting area to form a dark area. Thus, various light guide plates of patterns and characters are formed. Compared with the prior art, the present invention has advantages:

The invention can solve the glare problem without using the diffusion material, and after the diffusion material is removed (the reflective material can also be eliminated), the light can be directly emitted, and can be single, Double-sided illumination, expanding the angle of illumination, reducing energy consumption, improving light efficiency, and reducing costs;
( 2 )本发明应用更广泛， 不但可以用于照明、 也可以用于装饰， 艺术品 等， 光线均匀柔和（也可以通过网点设计调节局部明暗区域发光亮度）、 光线 射入后， 外形及图案生动美观、 形状千变万化、 节能环保。 可广泛应用于商 确认本 用及家用的实用照明及装饰照明灯具、 装饰品、 工艺品、 出路牌、 导向灯、 广告灯箱等。 附图说明 (2) The invention is more widely used, and can be used not only for illumination, but also for decoration, artwork, etc., the light is even and soft (the brightness of the local light and dark areas can also be adjusted by the dot design), the light is incident, the shape and the pattern Vivid and beautiful, the shape is ever-changing, energy saving and environmental protection. Can be widely used in business confirmation Practical lighting and decorative lighting fixtures, decorations, crafts, exit signs, guide lights, advertising light boxes, etc. DRAWINGS
