Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples, but the protection scope of the present invention is not limited to the following specific examples.

[0017] Such as Figure 1-2 As shown, the UVLED module with a composite lens disclosed in the present invention includes a substrate 1, a UVLED chip 2 and a composite lens. The UVLED chips 2 are provided with several and distributed on the substrate 1 in an array. The lens covers above the UVLED chip 2 .

[0018] The composite lens includes a first type of lens body 3, which is placed directly above the UVLED chip 2. The shape of the first type of lens body 3 is an oblate cuboid, and its length and width are The size just covers the UVLED chip 2 on the substrate; the composite lens also includes a second type of lens body 4, the second type of lens body 4 is placed directly ...

Abstract

The invention discloses a UVLED module with a composite lens structure and a preparation method thereof. The composite lens comprises a first lens body arranged on the upper surface of a UVLED chip and a second lens body arranged on the upper surface of the first lens body. The first lens body is in the shape of a flat rectangular solid. The second lens body is composed of a plurality of small lenses combined together, and the small lenses can be semi-cylindrical. The first lens body and the second lens body are prepared through two injection molding processes. Different materials with high cost performance can be chosen and combined. Different transmission effects are achieved at low cost. Thus, the application field of the UVLED module can be expanded.

Description

technical field [0001] The invention relates to the field of lens technology, in particular to a UVLED module with a composite lens structure and a preparation method thereof. Background technique [0002] In recent years, UVLEDs (ultraviolet light-emitting diodes) have been widely used in communications, electronics, optics, printing and other fields that require light curing technology. Compared with the traditional production process with mercury lamp irradiation as the mainstream, UV LED has the characteristics of constant light intensity, excellent temperature control performance, fast response time, portable and environmental protection, and relatively low purchase cost and almost zero The maintenance cost has greatly promoted the quality improvement and energy saving and consumption reduction of the UV curing process. In order to further promote the curing effect of UVLED, its light efficiency must also be increased. Due to the low single power of LED and the uneven...
