| Summary: | 碩士 === 國立高雄第一科技大學 === 機械與自動化工程所 === 94 === Abstract
In recent year, it is increasing and rapidly that the high intensity light emitting diode
（ LED ） is applied in the research of biotechnology. LED is provided with
characteristic of cooling light、small volume and saving power, and is driven by directed
current that is easy to be controlled and modulated, and the life time of LED is 10
multiple of fluorescent lamp. Now, there are many products that used the modulation
technique in multiple wavelength of LED. The research we want to do is the invention
that uses the technique of modulation and synchronizing in multi-wavelength LED.
Also we discuss the design of the phase shift between multi-wavelength LED. The
research which we develop is the function of the tuning in wavelength、frequency、duty
ratio、intensity and phase shift for modulating light. It is a very powerful instrument in
the study of photophysiology for biology.
