Abstract

The invention discloses a reflecting type condenser, an automotive light and an automobile, relating to the technical field of automobile manufacturing and aiming at solving the technical problems that the existing reflecting type condenser is low in efficiency and uneven in lighting. The reflecting type condenser comprises a reflecting type coupling surface, an incidence coupling surface and a total-reflection coupling surface, wherein energy of a light source is reassigned through the reflecting type coupling surface, and then sequentially subjected to the common action of the incidence coupling surface and the total-reflection coupling surface to form parallel light emission. The reflecting type condenser can change the light propagation path through the reflecting type coupling surface, so that the light ray number required by total reflection can be met; and light energy can be reassigned through the reflecting type coupling surface, so that the lighting effect can be optimized.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a reflective concentrator, a vehicle lamp and an automobile. Background technique [0002] figure 1 It is a schematic diagram of an optical path of a reflective concentrator provided in the prior art. [0003] The optical path characteristics of the reflective concentrator: the total reflection of the light on the paraboloid. like figure 1 Shown: 1. Light source; 1.1. The incident angle is smaller than the total reflection angle, and the total reflection light cannot occur; 1.2. The total reflection light; 2.1. The incident surface of the reflective concentrator: coupling surface 1; 2.2. The reflective concentrator The total reflection surface of the optical device: coupling surface 2. [0004] The materials commonly used for reflective concentrators are: PMMA, PC. The refractive index of PMMA is 1.489, and the total reflection angle is "42 degrees"; the ref...
