The Development Of Key Optical Technology And Intelligent Control Technology For High - End LED Ceiling Lamps

As a new generation of light source. LED has gained lots of attention and has been widely used in variety of indoor lighting environments. Not only because of its small size, but also because it has highlight effect, no toxicity and environmental protection. With the increasing development of society and people’s living standards, the requirements of indoor lighting are also rising. How to use intelligent control technology to achieve free transformation for lamps becomes the research focus of LED indoor lighting.Lighting and intelligent control solutions for high-end LED intelligent ceiling lamp have been provided in this dissertation. Lighting solution is to improve illumination uniformity and light efficiency, which can be achieved by optical design. Intelligent Control program aims to use mobile phones or other mobile terminals for remote control for lightings. The stepless dimming from 0 to 100 percent and colour temperature adjustment from 3200K to 6500K can be realized.First, the TracePro software is used for optical designing in this dissertation. To achieve uniform illumination, several individual LED must be mounted on panels. Therefore, the arrangement of the LED must be designed reasonably. Circular array method is familiar in ceiling lamp market, along with low illumination uniformity. In order to improve the uniformity, a three-dimensional array of hexagon mode has been presented. By changing angles of the multiple hexagons, the synergistic effect of light has been changed, thus, uniform illumination can be achieved. Through simulation, the optimum array model does output finally. At last, the effect of ceiling lamp has been verified in the founded interior space using DIALux software. Through calculation, the uniformity of working surface can up to 0.715 and can meet the uniformity requirements specified in the standard for interior lighting.The software development of intelligent control technology is to design an application based on Android and iOS platform, which will send instruction to lamps through Socket network technology. The lamps can be both separated control and network control to realize the scene lighting. Besides, SQLite database is used to realize the fixture management operations.A ceiling lamp sample has been made according to the LED array model and finally the test for optical parameters has been done. In the test results, color rendering index, photosynthetic efficiency, luminous flux can all meet design requirements. After the overall testing, the system can realize intelligent and humanization controlling on LED ceiling lamp. What is more, with the characters of high reliability and stability, it lays the foundation for the next product production.
