Abstract
In this paper a shell of 5W-LED which power supplied by the constant voltage was designed, the shell consisted of four components: a top cover, a base and two lateral covers.Its coat was made from PC, which has some remarkable properties such as excellent heat resistance, small forming contraction rate, high dimensional stability, high precision, high impact strength, small squirm, sturdy and resilient, etc. The blue print adopted the way of top-down the "top basic skeleton" as its core, and it means at the first with step in the design “basic skeleton” on the top level should be built according to the product's basic functions and requirements, which is also called "top basic skeleton". Subsequent design process including copy, modification, refinement, and finalizing the whole design were all based on the "top basic skeleton". At last the completed shell should meet the customers’ requierment about the function and service of the product.
