Abstract

The invention relates to a method of manufacturing a fluorescent powder shade by using a liquid silicone rubber injection molding technology and the fluorescent powder shade manufactured by the method and an LED (Light-Emitting Diode) lamp. The method comprises the following steps of: (1) mixing silicone rubber and fluorescent powder; (2) injecting a silicone rubber and fluorescent powder mixture into a mold taking the shape of the fluorescent powder shade; (3) rising the temperature of the silicone rubber and fluorescent powder mixture to a predetermined high temperature in a first very short time; (4) lowering the temperature of the silicone rubber and fluorescent powder mixture to a predetermined lower temperature in a second shorter time; and (5) demolding the molded fluorescent powder shade to obtain a finished product. According to the method, the complex technology of coating a fluorescent powder layer in the conventional technology and the low finished product ratio are avoided by independently injecting and molding the fluorescent powder shade; and the fluorescent powder shade can be produced in batches according to a standard technology and then is assembled on a shell of the LED lamp, therefore, the production efficiency and the rate of finished products can be greatly increased.
本发明涉及一种利用液态硅胶注塑技术制造荧光粉罩的方法以及由此制造的荧光粉罩和LED灯。该方法包括以下步骤:1)将硅胶和荧光粉混合;2)将硅胶荧光粉混合物注入具有荧光粉罩形状的模具内;3)在非常短的第一时间内将硅胶荧光粉混合物的温度提升到预定高温;4)在较短的第二时间内将硅胶荧光粉混合物的温度降至预定低温;以及5)将成型的荧光粉罩脱模得到成品。本发明通过独立注塑荧光粉罩可避免常规技术中涂覆荧光粉层的复杂工艺和低成品率,其中该荧光粉罩可以通过标准工艺进行批量生产,之后组装到LED灯的壳体上,由此可以极大地提高生产效率和成品率。
