The invention provides a lamp shell and a preparation method thereof. The preparation method comprises the following steps: providing a light metal shell; coating the surface of the light metal shell by using a micro-arc oxidation technology to form an insulating ceramic layer with a porous structure so as to obtain an intermediate molded part; an insulation layer is formed on the inner surface of the middle forming part through injection molding by means of the injection molding technology, and an insulation material of the insulation layer can permeate into the porous structure of the insulation ceramic layer in the injection molding process so that the insulation layer and the insulation ceramic layer can be connected in an embedded mode. According to the scheme, the insulating ceramic layer is directly formed on the surface of the light metal shell in an in-situ coating mode through the micro-arc oxidation technology, the insulating layer and the insulating ceramic layer are connected in an embedded mode, and therefore the heat transfer efficiency of the lamp shell is greatly improved.
本发明提供了一种灯具壳体及其制备方法。该制备方法包括如下步骤：提供一轻金属壳体；利用微弧氧化技术在所述轻金属壳体的表面包覆形成多孔结构的绝缘陶瓷层，从而得到中间成型件；利用注塑成型工艺在所述中间成型件的内表面注塑形成绝缘层，所述绝缘层的绝缘材料在注塑成型过程中能够渗入所述绝缘陶瓷层的多孔结构中，以使所述绝缘层和所述绝缘陶瓷层嵌合连接。本发明方案绝缘陶瓷层是直接利用微弧氧化技术原位包覆形成在轻金属壳体的表面，且绝缘层和绝缘陶瓷层之间是嵌合连接的，从而极大提高了灯具壳体的热传效率。
