Description
一种 LED导光板灯泡及其制作方法 技术领域 LED light guide bulb and manufacturing method thereof
本发明涉及照明灯泡， 尤其一种适用于各类照明、 艺术照明及装饰照明 等方面的 LED导光板灯泡及其制作方法。 背景技术 The invention relates to a lighting bulb, in particular to a LED light guiding bulb suitable for various lighting, art lighting and decorative lighting, and a manufacturing method thereof. 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、 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。 由于 LED是一种点光 源， 不能直接应用于照明， 直接使用会刺激人的眼睛。 现有的技术是通过很 多不同的如反射、 透镜、 直射式加扩散板等材料、 或整块侧边入光平面导光 板等方式将点光源转变为面光源的。 这样势必要增加能耗， 降低光效和提高 生产成本。已不能满足当前经济发展的需要。由于 LED光效越来越高，而 LED 是点光源而不能直接应用于照明， 所以必须通过二次发光形式达到照明目的。 现有的 LED灯泡是采用各种透镜、 扩散灯罩等材料遮光， 进行二次发光才能 达到不眩光或刺眼的发光效果， 而透镜和扩散用的灯罩等材料会有一定的遮 光作用， 不能完全把光线射出， 导致损失大部分能耗， 造成光效较低和生产 成本提高等缺陷。 发明内容 The design principle of the light guide plate is derived from the liquid crystal display of the notebook computer. The light guide plate uses a fluorescent lamp, a CCFL, and an LED light source to pass through a light guiding point or a light guiding groove calculated by an optical principle, and converts the line light source or the point light source into a surface light source 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. Since LEDs are a point source and cannot be directly applied to illumination, direct use can irritate the human eye. The prior art technology converts a point source into a surface source by means of a number of different materials such as reflections, lenses, direct-type diffusion plates, or monolithic light-in-plane light guides. This will inevitably increase energy consumption, reduce light efficiency and increase production costs. Can not meet the needs of the current economic development. Since the LED light effect is getting higher and higher, and the LED is a point light source and cannot be directly applied to the illumination, it is necessary to achieve the illumination purpose by the secondary illumination form. The existing LED bulbs are shielded by materials such as various lenses and diffusion lampshades, and the secondary illumination is used to achieve the glare-free or glare-like illumination effect, and the materials such as the lens and the diffusion lampshade have a certain shading effect, and cannot be completely Light is emitted, resulting in the loss of most of the energy consumption, resulting in defects such as low light efficiency and increased production costs.
