Abstract:
1. A lamp structure, comprising: a tubular lamp casing formed by a cover and a substrate supporter, wherein the cover is long-piece-shaped and long sides of the cover are fixed on two sides of the substrate supporter to form a tubular structure, the cover whose curvature has a light incident surface and a light outgoing surface and comprises a plurality of 3D micro-structures disposed thereon and arranged in the form of a matrix array; a light emitting diode (LED) array light source disposed in the tubular lamp casing for emitting a light, wherein when the light is emitted into the light outgoing surface from the light incident surface, the light emitting angle of the light outgoing surface is increased through the refraction of the 3D micro-structures; two end caps disposed at the two ends of the tubular lamp casing; and two couples of electrodes respectively disposed at two ends of the tubular lamp casing and mounted on the two end caps and electrically connected to the LED array light source.
