Therefore, energy saving product is getting more and more important in the market, such as the LED which is undoubtedly representative of the invention, it reduces power usage, comes in small size, long life and fast response time, etc. benefits. Although it has seemingly endless business opportunities, there are still several problems to overcome, such as light-emitting efficiency and how to further improve the effective heat dissipation, etc., among which the heat issue which will directly affect the life is more important, so the LED lamp radiating design is a necessary trend. Due to the complexity of light shade design, most of the traditional LED heat lamp are made up of the aluminum alloy material with the cutting, die casting or extrusion to make production. There are advantages and disadvantages of various processing methods, for example, extruded shape restrictions, high costs and long manufacturing time; Most of the manufacturers use die-cast production, but it is limited by material properties, even though the material is closer to the pure aluminum which has better heat features. Also because of the softness creates difficulty during secondary aluminum processing and it is heated illiquid, it usually uses aluminium-alloy instead in the marketplace. This piece of writing is about using the AL-1050 to forging the LED heat lamp, which is close to pure aluminum due to good thermal conductivity of aluminum while forging a product with high dimensional accuracy, structural strength, surface roughness, and no need to consider the material flow issues. This article starts from product design, through die exploitation, die manufacture,assembly of finished product and then comparison the process of experiments. First of all, designing the initial size of the heat lamp, sets with different numbers and thickness of the cylindrical cooling parameters, using thermal heat flow rate and the software to calculate the better appearance holder size leading to shape forming mold design, then the finite element simulation of metal forming process software to find suitable size of the material, forging temperature and the die rounded, …etc. parameters. Based on the simulation results determines parameters and the actual size of the die and die making to forge a LED heat lamp and the finished product and then consider the need to repair, and the final assembly of components for thermal efficiency and thermal efficiency of simulation experiments to compare and discuss. In this paper, using forging AL-1050 with the continuous die and can be mass-produced to reduce costs to meet the market demand.
