One is efficiency of light, and the other is efficiency of heat dissipation. The former decides the efficiency of LED illumination system. The latter decide the lifetime of system. The key of light output in the system is package. The package decides the light distribution .The heat dissipation is decided by the substrate or fin. Reflect cups and shape of fix lens decide light distribution in the commercial market, but reflect cups and fix lens fix the light distribution. Light distribution has to change in different environment. The fix lens and cups have to redesign to tunable light distribution. Tunable LED illumination system can deal with this kind of problem. LED combines with dielectric liquid lens to be a new generation illumination sys-tem in this thesis. The characteristic is tunable light distribution and good heat dissipation. First part is setup the optical system. According to simulation software design the package to connect the LED and liquid lens. The result of light distribution is changing form side emitting to focusing. The module of heat is setup by the simulation. The efficiency of heat dissipation can be 18 ℃ with package or not. The system has to measure the light flux and the reliability of system and compare to results of simulation and experiment. Yeh, Jer-Liang 葉哲良 2012 學位論文 ; thesis 70 zh-TW
