光產業的技術從類比轉向數位，產生的效果也從單一進入多元，結合不同的感測技術，讓光顯示從被動改為互動。技術創新讓光可以多元展現，突破過往平面化、室內化的侷限，可以擴大到奧運場地的長距離投影，也可以是個人穿戴科技的微投影。

應用光技術時，場域的擴大、情境的多元，讓光從配角成為主角，創造出新的商業模式。透過光的裝扮，夜景更為多采多姿，讓城市行銷不只有白天的風景，還有夜晚的繽紛，因應而生的各式商業價值創新，從硬體設備、軟體設計、行銷創意也蓬勃發展。

本論文彙整技術創新及商業價值創新模式，提供光產業分析價值創新模型。

The technology of the light industry develops from analog to digital, and the effect is also from single to multiple, combined with different sensing technologies to change the light display from passive to interactive. Technological innovation allows light to be displayed in multiple ways, breaking through the limitations of past flatness and indoor, and can be extended to the long-distance projection of the Olympic venue, or it can be the micro-projection of personal wearable technology.

When applying optical technology, the expansion of the field and the diversity of the situation make light become the protagonist from the supporting role and create a new business model. Through the dressing of light, the night scenes are more colorful, so that the city's marketing is not only the scenery of the day, but also the colorful of the night. All kinds of commercial value innovations that have arisen in response to this have also flourished from hardware equipment, software design and marketing ideas.

This paper integrates technological innovation and commercial value innovation model to provide a model for value innovation in light industry analysis.
