Combined-type lens and manufacturing method thereof

Abstract

The invention relates to a combined-type lens which comprises a lens supporting frame and a plurality of single-piece lens. Each single-piece lens has an edge, grooves matched with the edges are formed in the lens supporting frame, and each single-piece lens is fixed on the lens supporting frame through engagement of the edge and the corresponding grove. Preferably, the single-piece lenses are welded on the lens supporting frame through an ultrasonic welding device. The invention further provides a method for manufacturing the combined-type lens. By the combined-type lens, cost can be saved, product diversification can be realized through combining, a same frame can be combined with the lenses of different angles to achieve different effect, and product appearance changes can be adapted only by reopening the frame; a frame die needs to be accurate in size and does not need to be of an optical grade, so that cost is reduced greatly.

Description

technical field [0001] The invention relates to the field of LED light source lighting, in particular to a combined LED lens and a manufacturing method thereof. Background technique [0002] LED lights are widely used in various occasions, but because LED lights are directional light sources, most of them need to adapt lenses to change the light angle to improve light utilization and achieve efficient lighting and required light performance. At present, it is necessary to open a single integrated mold for each product or to adopt a separate lens, and the separate lens requires complicated assembly. [0003] A lens with a larger molding volume needs a longer injection time to shrink and reduce deformation to maintain its optical design angle. Therefore, although the integrated lens can save assembly time, it is necessary to open a new mold and it is a high-precision optical mold, which is not economical. And it consumes resources, and the production cost is not low and takes...

At present, it is necessary to open a single integrated mold for each product or adopt a separate lens, and the separate lens requires complicated assembly

[0003] A lens with a larger molding volume needs a longer injection time to shrink and reduce deformation to maintain its optical design angle. Therefore, although the integrated lens can save assembly time, it is necessary to open a new mold and it is a high-precision optical mold, which is not economical. And it consumes resources, the cost of production is not low and takes up a lot of mold opening time
