Abstract (en)
[origin: EP3726126A1] The invention discloses a tubular LED light fixture, comprising lamp holder; printed circuit board; a plurality of point light sources; lens; strip-shaped convex lens array, located between the lens and printed circuit board and arranged along the length direction of the tubular LED light fixture for converting each point light source into a plurality of consecutive sub point light sources, and the sub point light source converted by the adjacent point light source is connected or overlapped. The invention adopts a strip-shaped convex lens array which forms a line light source only by diffusing light from the point light source only in the length direction of the strip light fixture, preventing light from diffusing in multiple directions, so that the line source is purified. The lens is arranged to perform light distribution in the other direction to the line source, thereby reducing energy attenuation and ensuring the light effect.
