摘要

LED燈具具有較高的發光效率及指向性照明之特點，因此在未來重點式照明具有相當的利基點。本研究係延續LED燈具用於冷藏飲料冰櫃之研究，本研究是利用便利超商的冷藏櫃改用LED燈具，結合RFID控制設備，製作一智慧照明冷藏飲料展示櫃。吾人自行開發RFID驅動介面，此介面可調控RFID設備之訊號發送功率、掃描頻率…等參數，使冷藏飲料展示櫃配合軟體界面讓LED燈具凸顯冰櫃內商品，利用LED亮度可調控的特性作為照明之重點，此一系統利用RFID設備能夠達到易於取得需要之商品或特價飲料，快速的選擇展示冰櫃內的商品。本研究具有兩個特點：首先本研究成功開發更低功耗、更低電磁波掃描頻率之方法，降低射頻功率輸出達到相同效果。其次在於RFID定位控制系統在自開發軟體下，可由最大系統耗功45W下降至最大25W，且更可以在92%~100%的辨識情形下功耗降至20W以下，節約RF系統耗能44%以上。結合兩項科技配合節能技術後，以單一冷藏櫃而言總體約可節省65.6%冷藏櫃照明用電量，若使用於本校校內便利商店內預估可以節省63.56%冷藏櫃照明用電量，在未來提供節能又便利的生活環境。

LED lighting in the future with considerable focus on the niche point, as a result LED lamps have high luminous efficiency and the characteristics of directional lighting. In this study, continuation of LED lamps for the study applies to refrigerators. It is producing a refrigerator display intelligent lighting that using LED lamps on convenience store refrigerators and combined with RFID control equipment. Using self-developed RFID-driven interface, this interface includes RFID-control signal transmission power equipment, scanning frequency, etc. It is to enable LED lighting in the refrigerator to highlight products, therefore, customers would easy to find which is be needs or on sale items by using RFID system.
This research has two characteristics: First is the development of low-power and low-electromagnetic scanning; Second is RFID positioning control system for self-development software would reduce the largest power consumption from maximum 45W down to 25W, which will be able to 92% ~ 100% of the cases. Therefore, it can save energy for more than 44%. With two energy-saving technologies in terms of a single refrigerator can save about 65.6% of lighting electricity consumption. To apply the method in the convenience stores of our school, the power consumption would be saved over the 63.56%. There will be energy-saving and convenient living environment in the future.
