Problems solved by technology

Because of the limited angle of reflected light, the former cannot reach the irradiation range and the light loss is serious, which presents a glare and spot light source
However, the latter combination lens combined with multiple LED light sources will have serious defects such as light source dispersion, overlap and low light efficiency, which will affect the effect of use and fail to meet actual needs.

Embodiment Construction

[0013] The present invention is preferably specifically described below through examples, but the protection scope of the present invention is not limited thereto.

[0014] refer to figure 1 , figure 2 , an LED combined optical lens, comprising a transparent body, the transparent body has an inner curved surface for light collection and an outer curved surface for astigmatism, and the outer curved surface consists of a first astigmatism surface 7 and a second astigmatism surface in turn 6. The third astigmatism surface 5 and the fourth astigmatism surface 4 are formed around the central astigmatism surface 1. The first astigmatism surface 7 and the central astigmatism surface 1 are connected by a transition arc surface 8; It is connected with the second light-gathering surface 2, and the first light-gathering surface 3 and the second light-gathering surface 2 are arranged symmetrically in pairs.

[0015] The arc radius of the first astigmatism surface 7 is 45mm, the arc rad...

Abstract

The invention relates to an LED combined optical lens, comprising a transparent body having an inner curved surface for condensing light and an outer curved surface for diverging light. A first light-diverging face, a second light-diverging face, a third light-diverging face and a fourth light-diverging face surround a central light-diverging face sequentially to form the outer curved surface, wherein the first light-diverging face is connected with the central light-diverging face by a transitional cambered surface. First light-condensing faces and second light-condensing faces arranged pairwise and symmetrically are connected with each other to form the inner curved surface. With the combination of a plurality of condensing and diverging lens units, the invention can cooperate with a single high-power LED light source to produce uniform surface light source with soft ray and increased light intensity, thereby the invention has evidently effect on uniformity and comfort in light distribution, can effectively eliminate glare and ray shadow regions and significantly improve the light loss and rational control of area irradiated by the light source.

Description

(1) Technical field [0001] The invention relates to an LED composite optical lens. (2) Background technology [0002] Under the background of global energy shortage and increasingly serious environmental pollution, LED light sources (light-emitting-diodes) based on semiconductor light-emitting principles and their applications, which are famous for their energy saving, environmental protection, high efficiency, and long service life, are facing great market prospects. However, due to factors such as low power, low luminous efficiency, high price, short lifespan, etc., and the low utilization rate of light energy in the past, LED light sources were mainly used in traditional signal indication and low-end household flashlights, which affected and restricted its development and development. Therefore, the development and industrial application of high-power LEDs, especially LED convergent-dispersion combined optical mirrors, is more urgent and important. [0003] The LED optic...
