Abstract:
1. A lighting device comprising: a base element for electrical contacting and mechanical mounting; an LED arrangement comprising at least one LED element, said LED arrangement being arranged spaced from said base element along a longitudinal axis; an upper heat dissipating structure arranged next to said LED arrangement including at least two heat dissipation elements made out of a heat conducting material, said upper heat dissipating structure being shaped to include at least a first end and a second end spaced from said first end along a traverse axis which is at least substantially perpendicular to said longitudinal axis; said upper heat dissipating structure further having said at least two heat dissipating elements spaced from each other, said LED arrangement being provided between said at least two heat dissipating elements, wherein each of said at least two heat dissipating elements include at least two planar heat fins arranged under an angle with each other; wherein said upper heat dissipating structure has in cross-section perpendicular to said longitudinal axis an extension from said traverse axis small enough so that from a center of said LED arrangement at each of said ends a shading angle of 60° or less, caused by the at least two planar heat fins arranged under an angle with each other for each of the at least two heat dissipating elements, is formed and light from said LED arrangement is freely emitted outside of said shading angle.
