Abstract

The invention discloses an LED optical lens. The LED optical lens comprises an LED condenser part, a connection part and a light splitting part. The connection part is arranged between the LED condenser part and the light splitting part. The LED condenser part and the light splitting part are connected together through the connection part. The LED condenser part is composed of a TIR lens. The light splitting part is of a central cone core structure. The contour of the light splitting part is a stepped rotary body. The connection part is a cylinder. By means of the condensation collimation property and the optical total-reflection principle of the TIR lens, the LED optical lens which can generate a uniform visual effect and is composed of a plurality of concentric rings is provided for design of an automobile tail light. Besides, on the basis of the LED optical lens, the number of some scattering materials is increased or the number of other optical lenses is increased, and lamps of various shapes and visual effects can be derived.

Description

technical background [0001] The invention relates to the technical field of lighting, in particular to an optical lens that can be used in the optical design of vehicle lights. Background technique [0002] With the rise of the LED industry, LED has been widely used in all walks of life. Since the light intensity distribution of the LED is approximately a Heber cosine radiator, in order to meet different application requirements, it is necessary to carry out secondary optical design on the LED. [0003] Due to the advantages of high luminous efficiency, long life and small size of LEDs, in the automotive industry, LEDs have gradually replaced traditional light bulbs and become the mainstream light source for car lighting design. In the automotive lighting industry, especially the taillights, the special shape and visual effects are more and more valued by the market and welcomed by consumers. A car taillight with a sense of technology and fashion is the focus of everyone's ...
