Abstract (en)
Disclosed is an optical element of a vehicle light, the optical element comprising two optical parts, each of which is bent and comprising a light-condensing channel(13) and a light guide channel(14) connected to each other, with a junction therebetween being provided with a reflecting surface(15), wherein one end of the light-condensing channel(13) is provided with a plurality of light-condensing structures(11), and a front end of the light guide channel(14) is provided with an emergent light surface; and the two optical parts are arranged vertically, and the two light guide channels(14) are connected at the top and the bottom. The optical element of a vehicle light has the benefits of: 1, reducing the size of the optical element of a vehicle light in a fore-and-aft direction to reduce the space required for installation; 2, forming a primary optical element and a secondary optical element in the prior art as an integrated member; 3, providing a separation slot to achieve secondary light distribution so as to improve the flexibility of light distribution, and providing a sharp slot to achieve a passing light cut-off line and also simplify the structure of a vehicle light module; and 4, providing a groove so as to achieve both high beam and low beam functions in the integrated optical element of a vehicle light, such that the optical element of a vehicle light has diversified functions.
