The lower cost and higher reliability for LED source can be obtained through reasonable selection of materials and structure parameters of the LED lighting system.
Temperature distributions on packaging body are predicted under different materials and structure parameters.
For the optimization of LED packaging materials and structure parameters, the results show that the junction temperature can be decreased effectively by increasing the height of the heat sink, the width of the fin, and the thermal conductivity of the chip substrate and die attach materials.
The lower cost and higher reliability for LED source can be obtained through reasonable selection of materials and structure parameters of the LED lighting system.

It is should be noted that semi-solid processing will become a important forming method of simple, high efficient, low cost and good quality in the fields of materials processing. 1.
Therefore, it is necessary to widen research on semi-solid materials.
Semi-solid materials have been characterized by wide temperature interval between liquidus and solidus.
Furthermore, the forming temperatures of semi-solid materials have a limited influence on filling ability of slurry [31,32].
It has demonstrated that semi-solid materials are suitable for formation of both casting alloys and forging alloys.

Experiments Materials and Methods Experimental materials Three typical alkaline industrial wastes had been gathered from Shandong Province and made into experimental samples after drying, milling and screening.

Austenitic materials e.g.
On one hand they are single-phase materials and on the other hand it is possible to determine the grain size immediately after heat treatment.
Even after application the welding cycles the grain didn’t coarse significantly compared to materials S304H [8], TP347HFG [9].
