LED發光模組的應用頗為廣泛,如:交通道路指示號誌,汽車用指示燈,全彩化戶外顯示看板,光學指示,通訊裝置,室內、外照明以及醫療用途。目前技術人員重要課題之一為如何提高LED模組之電光轉換效益,另一重要課題為如何降低LED模組發光時之熱能。 本研究規劃設計之邊界型升壓式,主動功因修正電路及主動箝位返馳式轉換器之LED驅動模組電路,採用電路模擬仿真軟體TINA完成整體電路模擬。這種電路能提供95%的效率、更長的使用壽命,並能承受更高的電氣和機械衝擊。 本研究同時檢驗LED元件的特性,並藉由散熱基座連接於LED發光模組上,將LED發光時所產生的熱量吸收,再由傳導方式消散熱量,傳送至周遭環境中。此結構的LED模組可以提高發光的功率,簡化製程,應用於照明。
LED light module of the application is rather broad, such as: traffic and road direction signs, automotive lights, full-color display of outdoor billboards, optical direction, communication devices, indoor and outdoor lighting, as well as medical purposes. Technical staff is currently one of the important topics of how to improve the LED modules of the electro-optical conversion efficiency, another important issue of how to reduce the heat when the LED light module. This study planning and design of the boundary-type step-up, active power factor correction circuitry and active clamp flyback converter module of the LED driver circuits, using circuit simulation software to complete the whole TINA circuit simulation. This circuit can provide 95% efficiency, longer life and can withstand a higher electrical and mechanical shock. The study also tested the characteristics of LED components, and by cooling the base connected to the LED light module, LED light will be generated when the heat absorbed by the dissipation of heat conduction, transfer to the surrounding environment. The LED module of this structure can increase the luminous power, streamlining processes, used in lighting.
