Abstract

The present invention puts forward an LED arch-shaped lens forming method capable of manufacturing an LED lens of which the surface is in an arch shape. The LED arch-shaped lens forming method comprises the following steps: S1, preparing an LED lens mold, wherein a part, used for injection of a mixture of fluorescent powder and molding gel, of the mold is in a circular shape at the bottom, and is gradually expanded upwards in an arc shape, an opening at the top end is in a circular shape, and the edge of the opening is provided with an upward projection; S2, injecting the mixture of fluorescent powder and molding gel into the LED lens mold; and S3, enabling the mixture of fluorescent powder and molding gel to form a raised LED arch-shaped lens under the action of surface tension. An LED arch-shaped lens or hemispherical lens manufactured by adoption of the LED arch-shaped lens forming method has a larger light-emitting surface, and lights emitted by the LED arch-shaped lens or hemispherical lens are intersected with each other, thus the lights emitted integrally have better color consistency.

Description

technical field [0001] The invention relates to a method for forming an LED lens, in particular to a method for forming an LED arched lens. Background technique [0002] Existing LED lenses are generally made by injecting phosphor powder mixed top glue into a square or round mold to form a square or round LED lens. The color consistency of the LED lens made by this method is not good enough, and the light-emitting surface is small. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention proposes a method for forming an LED arched lens, which can manufacture an LED lens with an arched surface. LED arched lens forming method of the present invention comprises the following steps: [0004] S1: Prepare the LED lens mold. The bottom of the part of the mold used to inject the mixture of phosphor powder and mold top glue is circular and gradually expands upwards in an arc shape. The uppermost opening of the mold is circul...
