The invention relates to the field of the optical technology, in particular to a free-form surface optical lens. The free-form surface optical lens comprises a lens and a protective cover. The periphery of the lens is fixedly connected with the protective cover, a basic layer is fixedly arranged in the lens, the top end of the basic layer is fixedly connected with a light-transmitting layer, the top end of the light-transmitting layer is fixedly connected with a blue light filtering layer, the top end of the blue light filtering layer is fixedly connected with a refraction layer, a concave surface is fixedly arranged on the top of the refraction layer, the bottom end of the basic layer is fixedly connected with an anti-dizziness layer, and the bottom end of the anti-dizziness layer is fixedly connected with transparent protrusions. The free-form surface optical lens is novel in design and simple in structure, and has a good light-transmitting effect, meanwhile, the irradiation area ofa light source can be effectively increased, next, a certain anti-dizziness effect is achieved, a light pollution phenomenon is not easily caused, and the free-form surface optical lens is practical and suitable for being widely used and popularized.
Description
technical field [0001] The invention relates to a lens, in particular to a free-form surface optical lens, and belongs to the field of optical technology. Background technique [0002] LED has become the most common light source today, because LED has the advantages of small size, fast response, energy saving and environmental protection, etc., it is widely used in road lighting, car headlights and backlight display and other fields. These applications require LEDs to have high color uniformity sex. [0003] However, because LED is a surface light source, the light output angle is small, which makes its color uniformity poor, the irradiated light is more dazzling, and it is easier to cause light pollution, so that the LED light source cannot be maximized. Therefore, it is very important to design a free-form optical lens. necessary. Contents of the invention [0004] The purpose of the present invention is to provide a free-form surface optical lens in order to overcome ...
