1. An optical imaging lens assembly, comprising, sequentially along an optical axis from an object side to an image side:
a first lens, having a negative refractive power, an image-side surface of the first lens being a concave surface;
a second lens, having a positive refractive power, an object-side surface of the second lens being a convex surface; and
a third lens, having a refractive power, an object-side surface of the third lens being a convex surface,
wherein the optical imaging lens assembly satisfies:
3 mm<ImgH×f/EPD<4 mm; and
1 mm<tan(FOV/2)×f<2 mm,
wherein ImgH is a half of a diagonal length of an effective pixel area on an image plane of the optical imaging lens assembly, f is an effective focal length of the optical imaging lens assembly, EPD is an entrance pupil diameter of the optical imaging lens assembly, and FOV is a maximal field-of-view of the optical imaging lens assembly.
