技术领域 technical field
本发明涉及一种照明区域色温选择性分布的方法。 The invention relates to a method for selectively distributing color temperature in an illumination area.
背景技术 Background technique
发光二极管(Light Emitting Diode-LED)具有色彩丰富、电光转换效率高、体积小、寿命长、安全、节能、环保等诸多优点，广泛应用于显示屏、交通信号灯、汽车内外部灯、显示器背光源等应用领域，目前直接目标是取代白炽灯和荧光灯，成为第四代照明光源。半导体照明光源与传统光源相比，具有资源节约与环境友好的特点，受到世界多个国家、研究机构和企业的重视。日本、美国、欧盟、韩国等国家近年来相继推出国家半导体照明计划。中国是世界照明电器生产、出口大国，又是消费大国。LED 产业在这样的经济大环境之下必然存在巨大的市场空间，但分布在美国、日本、欧盟等地的半导体照明主要厂商，拥有核心技术专利，利用其专利方面的优势，试图通过设置专利壁垒和制定行业标准来控制市场。中国企业和研究机构应加强自主创新能力，应该争取获取尽可能多的专利，或多角度的专利池，努力化解中国企业随时面临着的专利侵权风险。 Light emitting diode (Light Emitting Diode-LED) has many advantages such as rich colors, high electro-optic conversion efficiency, small size, long life, safety, energy saving, environmental protection, etc. And other application fields, the current direct goal is to replace incandescent and fluorescent lamps and become the fourth generation of lighting sources. Compared with traditional light sources, semiconductor lighting sources have the characteristics of resource saving and environmental friendliness, and are valued by many countries, research institutions and enterprises in the world. Japan, the United States, the European Union, South Korea and other countries have successively launched national semiconductor lighting plans in recent years. China is not only a big producer and exporter of lighting appliances in the world, but also a big consumer. Under such an economic environment, the LED industry must have a huge market space, but the major manufacturers of semiconductor lighting distributed in the United States, Japan, the European Union and other places have core technology patents. Taking advantage of their patents, they try to set up patent barriers. And develop industry standards to control the market. Chinese enterprises and research institutions should strengthen their independent innovation capabilities, strive to obtain as many patents as possible, or multi-angle patent pools, and strive to resolve the patent infringement risks that Chinese enterprises face at any time.
在大多数照明场合，对照度、色温和显色指数等光参数指标存在基本的要求。某些场合在显色指数和色温满足要求的前提下，要求照度在一定范围内变化。有些场合要求特别，希望在显色指数和照度满足要求的前提下，色温在一定范围里变化。采用半导体照明光源，相对于传统光源来讲比较容易实现这些要求。专利：可调整亮度及分区点亮光源的混光式发光二极管封装结构（申请号201020243231.2），提出一种可调整亮度及分区点亮光源的混光式发光二极管封装结构，利用多个不同色温LED光源及改变驱动电流组合的方法，构成亮度和色温可控的照明光源。专利：一种 LED 出光颜色可控的新型封装方法和装置（申请号201110050107.3），提出一种 LED 出光颜色可控的新型封装方法和装置，在一种面积较大并且导热性能良好的金属材料上通过布置点胶外框划分热沉区域，然后固晶、焊线和点胶，从而实现了在同一个光源上的不同区域发出不同颜色的目的，同时通过电路还可以控制光源变化颜色。上面两个专利均通过控制不同LED光源组合和驱动电流，实现颜色、色温和亮度变化的。本发明使用环境更为特别，要求光源的照明区域内相关色温有选择性的分布，既在不同照明区域内有可控的不同相关色温，充分显示出LED光源有别于传统光源的魅力，满足特殊场合的使用要求。需要说明的是：虽然有把红色发光二极管芯或红色发光二极管嵌在白光发光二极管芯或白光发光二极管中的灯具，但它这样做的目的是降低相关色温和提高光效，把红色发光二极管芯和白光发光二极管芯作为一个整体使用，红色发光二极管芯均匀分布在白光发光二极管芯之中，希望得到相关色温均匀一致的光斑，常采用透射均光板来实现良好的混光效果。 In most lighting occasions, there are basic requirements for light parameter indicators such as contrast illuminance, color temperature and color rendering index. In some occasions, under the premise that the color rendering index and color temperature meet the requirements, the illuminance is required to change within a certain range. Some occasions have special requirements. It is hoped that the color temperature will change within a certain range under the premise that the color rendering index and illuminance meet the requirements. Compared with traditional light sources, using semiconductor lighting sources is easier to achieve these requirements. Patent: Mixed light-emitting diode packaging structure with adjustable brightness and partitioned light source (application number 201020243231.2), proposes a mixed light-emitting diode packaging structure with adjustable brightness and partitioned light source, using multiple LEDs with different color temperatures The light source and the method for changing the driving current combination form an illumination light source with controllable brightness and color temperature. Patent: A new packaging method and device with controllable LED light emission color (application number 201110050107.3), proposes a new packaging method and device with controllable LED light emission color, on a metal material with large area and good thermal conductivity By arranging the dispensing frame to divide the heat sink area, and then solidifying the crystal, bonding wires and dispensing glue, the purpose of emitting different colors in different areas on the same light source is achieved, and the color of the light source can also be controlled through the circuit. The above two patents realize the change of color, color temperature and brightness by controlling the combination of different LED light sources and driving current. The application environment of the present invention is more special, requiring the selective distribution of correlated color temperature in the lighting area of the light source, which not only has controllable different correlated color temperatures in different lighting areas, but also fully demonstrates the charm of the LED light source which is different from the traditional light source, and satisfies Requirements for special occasions. It should be noted that although there are lamps that embed the red light-emitting diode core or red light-emitting diode in the white light-emitting diode core or white light-emitting diode, the purpose of doing so is to reduce the correlated color temperature and improve light efficiency. It is used as a whole with the white light-emitting diode core, and the red light-emitting diode core is evenly distributed in the white light-emitting diode core. It is hoped to obtain a light spot with uniform correlated color temperature, and a transmission uniform light plate is often used to achieve a good light mixing effect.
