碩士 === 國立成功大學 === 電機工程學系專班 === 96 === In the recent years, the light emitting diodes was development very quickly, the luminous efficiency had already exceeded (100lm/w), and the traditional fluorescent lamps of luminous efficiency only had (80lm/w). At present, the light emitting diodes (LEDs) luminous efficiency were enough to replaced traditional fluorescent lamps. But follow according to the research paper of “industrial technology research institute”. The main bottleneck lies are the LEDs cost higher than traditional fluorescent lamps nearly 10 times, and the luminous efficiency need 2 times improve. When the time comes, the LEDs can replace the traditional fluorescent lamp, and save the waste of the energy for the earth. In this paper, our group was development with electroless technology. By this method, compare with the traditional e-gun evaporated, the electroless plating technology have advantage of lower cost and fast process time and simple process etc. The experiment result shows that the LEDs device prepared by electroless plating acts could reduced of cost, the other optical and electro- characteristics have not changed. The comparisons of optical and electro- characteristics and cost between electroless and traditional ones were discussed later.
