隨著數位相機流行，為了攜帶方便，機身必須越做越小，因此包含鏡頭等各部分元件也隨之減少體積。閃光燈為相機必要元件之一，其小型化也是必要趨勢。然而，在小型化的同時還必須兼顧效能的維持，這是一項不容易的挑戰。除了數位相機的閃光燈必須小型化之外，手機鏡頭也必須搭配閃光燈，這類型閃光燈對於小型化更加有需求。目前絕大部分手機閃光燈並無光學設計，也未符合閃光燈對於照相的要求，因此將閃光燈縮小，並維持光學效能對照相機或是有照相功能的手機來說是一個重要課題。
本文描述了利用全反射（T.I.R.）原理設計閃光燈。提出自由曲面設計的方式，另外對於T.I.R.原理及應用，LED光學特性，閃光燈設計要求也一併討論。最後以一個實際設計範例，設計一款規格為1M處FOV60度Shading值小於-1EV之LED閃光燈。
Prevail with digital cameras, in order to carry convenient, must make the smaller with the camera, so include reduction volume of every part of componentses such as the lens,etc.. The flashing lamp is one of the essential components of camera, its miniaturization is an essential trend too.Besides necessary miniaturization of flashing lamp of the digit camera, the mobile phone camera must match the flashing lamp too, there is a demand further for miniaturization in the flashing lamp of this type.
This text description utilizes the total reflection (T.I.R.) Design the flashing lamp in principle. Put forward the way in which the curved surface of freedom is designed, in addition to T.I.R. principle and application, LED optical characteristic, the designing requirement of the flashing lamp is discussed together too. Design the example actually by one finally, design a specification to be that 1M FOV60 one degree of Shading value is less than - LED flashing lamp of 1EV.
