LED matrix type ground projection module

Abstract

The invention relates to a light-emitting diode (LED) matrix type ground projection module, which forms a new optical system through silica gel inner matching and glass inner matching with special structures, so that a traditional light source can realize projection in front of a vehicle. Each condenser can independently control light distribution, and fine adjustment of ground projection light distribution can be achieved. A single LED is matched with an independent condenser, and individual car front projection patterns can be formed through independent matrix light patterns according to user requirement definition. The distributed LED layout can effectively avoid heat concentration, is high in heat dissipation efficiency, effectively reduces LED junction temperature, and has the advantages of being long in service life, high in reliability and the like. According to the design, the front projection cost of the vehicle is greatly reduced, the driving pleasure is increased, the projected specific pattern provides more visual road information for other road participants, and the driving safety is increased.

Description

technical field [0001] The invention relates to a projection technology, in particular to an LED matrix type ground projection module. Background technique [0002] With the popularization of autonomous driving technology, lamp projection has become an indispensable part of the information interaction between vehicles. At present, the traditional lamp projection group relies on the DMD (digital micromirror device) mechanism to reflect the light source and project it onto the ground to form a personality. The advantages of converting the front projection pattern of the car are that the megapixel-level projection has high resolution and rich patterns; the disadvantage is that the mechanical mechanism is complex, the DMD system is patented by TI, and the cost is high, making it unaffordable for ordinary civilian-level family cars. SUMMARY OF THE INVENTION [0003] Aiming at the problem of high cost of front projection by DMD mechanism, an LED matrix ground projection module i...
