“…Creating a merger between one blue InGaN chip and yellow-color YAG:Ce would be now the most popular method to generate white illumination [3]. Without sufficient red illumination, such a type of white radiation has a small hue rendering indicator (CRI ≈ 70-80) as well as a huge correlated hue temperature (CCT≈7500 K) [4], [5]. Many scientists have been studying red phosphors that are triggerable using blue lighting in recent years.…”

“…Thus, it is essential for manufacturers to have an alternative material whose matrix has high thermal stability to attain high performance. Several matrix materials were introduced with high thermal stability and average optical efficiency for WLED mixed phosphor base, including the ceramics matrix [7], [8] and glass matrix [9], [10]. These two matrixes are produced by applying recrystallizing method at high temperature (above 1000 o C), and this technique probably increases the cost of thermal- 1961 durable phosphor fabrication.…”

“…Another one is the use of a patterned remote phosphor structure with an empty perimeter that has no coating phosphor on the surrounding surface in achieving better angular-dependent correlated color temperature and high chromatic stability [14]. In addition, the remote phosphor structure that has the patterned sapphire substrate in it perform better than a common pattern as benefits the uniformity of correlated color temperature in the radiation-zone field [15]. The proposal suggest using remote phosphor structure WLED with two phosphor layers to achieve the goal of enhancing the light emitted from LEDs.…”
