Abstract

The invention provides a PES light-path double-reflector structure and an automotive lamp PES unit thereof, and relates to arrangement of common vehicle illuminating or signal devices, in particular to a double-reflector structure for design of a light path of the automotive lamp PES unit and the automotive lamp PES unit using the double-reflector structure. The PES light-path double-reflector structure comprises a first auxiliary reflector and a second auxiliary reflector, wherein the first auxiliary reflector is used for collecting residual light; the second auxiliary reflector is used for guiding the residual light into a lens projection light path; the first auxiliary reflector is configured in a region illuminated by the residual light of an LED light source; the second auxiliary reflector is configured in the direction which is opposite to the first auxiliary reflector; the residual light is reflected and gathered on the second auxiliary reflector via the first auxiliary reflector, then is gathered to a focal point of the lens by the second auxiliary reflector, and is projected to a projection target area through the lens, so that light energy of the residual light can be used again, the pavement illuminating effect of the automotive lamp PES unit is improved, illuminating brightness and an effective illuminating distance of an automotive lamp are increased, and safety of an automobile running at night is improved.

Description

technical field [0001] The invention relates to the arrangement of general vehicle lighting or signaling devices, and in particular to a double reflector structure used for the optical path design of a vehicle lamp PES unit, and a vehicle lamp PES unit using the double reflector structure. Background technique [0002] As a major invention in automotive lighting, PES has the characteristics of small size, high energy utilization rate, uniform light pattern, and clear cut-off line. China's invention patent application "A PES unit with ADB function of LED far and near lights for car lights" (invention patent application number: 201610097273.1 publication number: CN105570794A) discloses the basic structure of a car light PES unit. High beam LED circuit board small assembly, low beam LED circuit board small assembly, reflector; high beam LED circuit board small assembly is fixed with a concentrator directly in front of the high beam LED circuit board small assembly; when the low...
