light beams 90 b 91 b 92 b accordingly as each of the light beams 90 a 91 a 92 a is traveling from a sparse media into a dense media thereafter the three first refracting light beams 90 b 91 b 92 b are further respectively incident to their corresponding portion of the second refraction surface 22 they are refracted away from the normal vector of its corresponding portion and forming three discharging light beams 90 c 91 c 92 c accordingly as each of the light beams 90 b 91 b 92 b is traveling from a dense media into a sparse media eventually by the abovementioned two refraction the three discharging light beams 90 c 91 c 92 c are directed to travel in a direction perpendicular to the central axis of the light source package structure 2 in fig6 b a refraction cap is arranged at the upper portion of the light source package structure and is designed to receive the portion of the first refracting light failed to incident to the second fraction surface directly so as to form a second discharging light to be emitted therefrom in a direction perpendicular to the central axis of the light source package structure first when the light beam 93 a emitted from a led is incident to its corresponding portion of the tapered structure 310 of the first refraction surface 31 it is.
