Abstract
An LED lamp light distribution system and illumination system, the illumination system comprises an LED lamp light distribution system, and at least one illuminated surface. The LED lamp light distribution system comprises an LED chip, a lens, and a light reflecting device. The lens comprises a lens optical axis, a light source setting groove, and an exit surface. The light source setting groove comprises a first contour line, and the exit surface comprises a first exit surface contour line. The first contour line and the first exit surface contour line complete the convergence of the emergent light of the LED chip toward the lens optical axis. The light source setting groove comprises a second contour line, the exit surface comprises a second exit surface contour line, and the second contour line and the second exit surface contour line complete the diffusion of the emergent light of the LED chip away from the lens optical axis. The illuminated surface is perpendicular to the reflecting plate and the lens optical axis. The illumination system can provide users with specific lighting effects to meet the needs of users.
