| Summary: | 碩士 === 國立中央大學 === 光機電工程研究所 === 97 === The main objective of this thesis is to design the interior lighting system by using the LED source. According to the types of the source and the methods of the design, three kinds of designs including the middle/low power, high power, and quasi-surface lamps are proposed in this research.
The second optical lens by the refraction and reflection are utilized in the designs of the middle/low power and high power lamps. The middle/low power lamps use the middle/low power LED with the powers within 0.1~1 W. A number of middle/low power LEDs develop the typical arrays to increase the overall luminous intensity. The high power lamps use the high power LED with the power greater than 1 W. By using the second lens and micro lens array to adjust the distribution of the exit light angle, the single high power LED with improvement of the yellow circular can be used efficiently.
The side-emitting lens, the reflecting surface, and the micro-lens array are three important elements in the design of quasi-surface lamp. The side-emitting lens and reflecting surface can be used to increase the luminescence area and to decrease the luminous intensity per unit area. We also add the micro-lens array to adjust the distribution of the exit light angle to promote the efficiency.
In the end of this thesis, the data of simulations are compared with the actual measurements of the lamps to prove the feasibility of the method of design and simulation.
