Abstract


Solid lighting source is a light-emitting diode (LED) as a light source for the design of lighting systems , can not only save energy , reduce pollution , and can reduce the system volume , and extend the life of the system . However, due to the different shape and light-emitting properties of the LED and the existing light source , making the existing lighting system can not be directly applied to the LED , which specialized optical design must be based on the demand for LED lighting . It is optical design method of the LED lighting system has both theoretical value and contains practical significance . For common lighting requirements , the subject of the LED array arrangement using the edge of the light theory grid method to construct the optical freeform uniform illumination optical system design methods to achieve high energy utilization exploratory study : LED array row cloth problem: in the known optical radiation characteristic of the light source and the target surface is required for the illuminance distribution under the premise , to create a light source mathematical model , based on the knowledge of differential geometry , the calculated LED illumination uniformity of the target surface is achieved extremum arrangement interval size. Made a variety of applicable model of the optical arrangement of the illumination system in accordance with reality , in order to achieve the object of the uniform illumination . The structural problems of the free curved surface : In the known optical radiation characteristic of the light source and the target surface is required for the illuminance distribution premise , divided based on the principle of light flux conservation energy grid , and then according to the edge ray theory , as well as optical catadioptric theorem, iterative freedom Surfaces face data . Applies to the lighting system of the free-form surface optical model is based on reality , and 100% of the theoretical energy utilization by the light source embedding method of free-form surfaces . This subject then the use of the above design theory to design a variety of arrangement of the LED array , and capable of forming a uniform illumination round spot , and the rectangular spot optical system , and use of the optical simulation software Tracepro verified on various design , proved that the design of the correct and validity .
