The developed nations lately emphasize the concepts of energy saving and environmental protection; Therefore LED gains saving much attention due to its advantages, such as no mercury pollution and low power consumption. Still the key issue is to improve the lighting efficiency.
This thesis using optical design and simulation software called SPEOS to model the various directivity LED lamps and optimize their geometrical parameters to extract maximum output power. It is shown that for FWHM (Fall Width Half Maximum) angle equal to 120 degree, 100 degree, 80 degree, 60 degree, the improvement of power is 10.97%, 9.95%, 7.49%, 4.39% respectively. Using the methods which optimize the geometrical parameters can achieve our goal.
