Illumination structure and lamp tube structure for generating specific directional light sources

An illumination structure for generating specific directional light sources, comprising:

• a substrate unit having at least one substrate body;
• a light-emitting unit having a plurality of light-emitting elements disposed on and electrically connected to the at least one substrate body;
• and
• a lens unit having a lens module disposed on the at least one substrate body, wherein the lens module has a lens frame disposed on the at least one substrate body and a plurality of protruding lens elements separated from each other by a predetermined distance and integrally formed on the lens frame, the protruding lens elements respectively correspond to the light-emitting elements, and each protruding lens element has at least one concave portion formed on a top side thereof and above each light-emitting element and at least two protrusion portions respectively integrally connected to two opposite sides of the concave portion.

A lamp tube structure for generating specific directional light sources, comprising:

• a substrate unit having at least one substrate body;
• a light-emitting unit having a plurality of light-emitting elements disposed on and electrically connected to the at least one substrate body;
• a lens unit having a plurality of lens modules sequentially abutted against each other and disposed on the at least one substrate body, wherein each lens module has a lens frame disposed on the at least one substrate body and a plurality of protruding lens elements separated from each other by a predetermined distance and integrally formed on the lens frame, the protruding lens elements respectively correspond to the light-emitting elements, and each protruding lens element has at least one concave portion formed on a top side thereof and above each light-emitting element and at least two protrusion portions respectively integrally connected to two opposite sides of the concave portion;
• a heat-dissipating unit having at least one heat-dissipating element disposed on a bottom side of the at least one substrate body;
• a lamp shell unit disposed above the lens unit;
• and
• a lateral cover unit having two cover elements, wherein the substrate unit, the light-emitting unit, the lens unit, the heat-dissipating unit and the lamp shell unit are disposed between the two cover elements.
