白光發光二極體比起傳統的白熾燈及螢光燈有更多優點，如具有高穩定性、使用時間長及消耗功率小等等。因此，白光發光二極體被視為世界上未來最有發展潛力的固態照明。
本論文主要是在白光LED的光學設計與照明分析。在光學設計部分，我們目的要燈具在距離2公尺，面積為2*2平方公尺的工作面上有300Lux的均勻照度。所以照明的配光曲線為蝙蝠翼光場，最大的光強角度在27度，與0度角相比約為0.71。我們利用光學模擬軟體LightTools進行透鏡出光面的設計，改變LED光場的分佈。配光曲線設計完成後，需要9個LED組成一個燈具，才能使工作面上約有300Lux的平均照度。再針對這個LED模組進行工作平面上的均勻照度優化，可使均勻達到0.9，使這個模組能用於室內照明。
在照明分析部分，把LED燈具和螢光燈用於一個室內空間作比較。比較之間的結果，可發現LED燈具的照明利用率為0.682高於螢光燈管的照明利用率0.394。LED燈具在單位面積下產生100Lux需要2.29W，而螢光燈在單位面積下產生100Lux需要2.56W。能證實LED燈具能比螢光燈管省電。

White light LEDs have more advantages than those of traditional incandescent lamps and the fluorescent lamps; e.g. high stability, long life time and low power consuming etc. Therefore, white light LEDs have been regarded as the most potential light source of solid-state lighting (SSL) in the future.
In this thesis, we focus on the white light LED optical design and illumination analyses. For the optical design issue, our purpose is to design a 300-Lux lamp on the work plane which is 2 meter away with LED with 4 square meters in size plane and has uniformity illumination. The luminous intensity distribution curve shape is a batwing distribution and the maximum luminous intensity around 27° which compares with 0° approximately is 0.71. We focus on the design of LED lens using the LightTools software to improve the light distribution of white light LED. After the luminous intensity distribution curve design is completed, the lamp needs nine LEDs to enable the work plane approximately to have 300 Lux. Next, we optimize the lamp to enhance the uniformity illumination on the work plane. The uniformity illumination is promoted to 0.9.
For the illumination analysis issue, we use the LED lamp and the fluorescent lamp in the indoor space making the comparison. According to the comparison results, the utilization factor of the LED lamp is 0.682 higher than the utilization factor of the fluorescent lamp is 0.394. The LED lamp produces 100Lux which needs 2.29W is smaller than the fluorescent lamp produces 100Lux which needs 2.56W in the unit area (1m2). It proved that the LED lamp has low consumption when compares to that of the fluorescent lamp.
