Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a projected LED low beam lamp for automobiles. Background technique [0002] With the concepts of energy saving, environmental protection, nobility and driving safety being more and more valued by the automobile consumer market, LED has the advantages of energy saving, good color rendering, simple structure, fast response, low voltage, small size and long life. , There is a great tendency to replace traditional halogen lamps and xenon lamps. As a new type of lighting source, LED has the potential to dominate the automotive lighting market. Early LEDs were mainly used in lighting environments with low brightness requirements such as reading and instrument indication. With the higher and higher luminous efficiency and brightness of LEDs, LEDs have also begun to play a role in automotive headlight lighting. LEDs have achieved good results and economic benefits as taillights, turn...
