用圆形LED改制异型或复色LED
常见的圆形塑封发光二极管的直径有φ3、φ3.5、φ4、φ10等多种。其外形如图所示。
图是4-3（b）、（c）、（d）用锉刀和钢锯加工成的发光二极管。加工后需用竹签缠脱脂棉，沾牙膏摩擦抛光。如嫌不光泽，可将整个发光二极管往氯彷液中放一下，叙述提起，然后放在通风的地方晾干，这时LED面貌焕然一新。
图4-3（e）、（f）是用钢锯两道口子，然后在锯口中滴入少许吕方后，再鑲嵌彩色有机玻璃片，待彩色有机玻璃片贴牢后，用什棉锉修磨成圆弧状，再用布条沾牙膏摩擦抛光，成为多色圆形发光二极管。

The processing method of Figure 4-3 (g) is the same as that of Figure 4-2 (g). Do not drill too deep to avoid damaging the LED die. For information on LEDs, please refer to Appendix 44.
