The present invention provides a lighting device based on light emission of total internal reflection (TIR) critical curvature radius, it particularly relates to a novel style design that effectively saves power and distributes light expansion, mainly comprising a light source, a light transmission unit that comprises a transparent light-guide path extending from one end, and at least one light emission unit formed on the transparent light-guide path. The transparent light-guide has an end connected to the light source. The light emission units have a radius of curvature that is smaller than that of the transparent light-guide path. As such, the present invention uses the radius of curvature of the light emission units being smaller than the radius of curvature of the transparent light-conducting path to allow the light emission from the light source to be guided through the transparent light-guide path and emitted from the light emission units so as to achieve a practical benefits of saving power and materia
