Line source lighting system

A line source lighting system, comprising:

• a lamp holder (100);
• a printed circuit board (200), disposed on the lamp holder (100);
• a plurality of point light sources (300), disposed spaced apart from each other along a lengthwise direction of the lamp holder (100) on a light source mounting surface of the printed circuit board (200) and;
• a strip-shaped convex lens array (500) placed on top of the plurality of point light sources (300) and arranged along the lengthwise direction of the lamp holder (100) for converting each point light source (300) into a plurality of continuous sub-point light sources, the sub-point light sources converted by the adjacent point light source (300) are connected or coincident;
• and
• at least one lens (400), disposed on the lamp holder (100) and located in a light-emitting direction of the point light source (300) for adjusting light distribution of the point light source (300) on a plane perpendicular to the lengthwise direction of the lamp holder (100);
• wherein the strip-shaped convex lens array (500) is located between the lens (400) and the printed circuit board (200).
