Abstract
A light distribution system of an LED strip lamp, comprising a light source module, a reflective device disposed in a light-emitting direction of the light source module, and an illuminated surface which receives the reflected light from the light reflective device, the illuminated surface includes a ground surface and a main illuminated surface perpendicular to the ground surface, the light source module includes at least one LED chip, each of the LED chips has an optical axis, the optical axis is perpendicular to the vertical, in the cross section along the vertical direction and the optical axis, the reflective device includes a main reflective surface, it is difficult for the light to directly enter the eyes of the user, so that it can achieve the purpose of preventing glare.
