Abstract
A lighting device includes a light source and an optical element, the light source includes a plurality of light emitting diodes aligned. The optical element being shaped to focus a light beam emitted by the light source in a plane orthogonal to the line of light emitting diodes and to deflect said light beam parallel to an illuminating plane including the line of light emitting diodes so as to form a light beam having an ellipsoidal section.
Claims7
A lighting device, comprising:
- a light source;
- and
- an optical element,
- wherein the light source comprises a plurality of light emitting diodes aligned, and wherein the optical element is shaped to focus a light beam emitted by the light source in a plane orthogonal to the line of light emitting diodes and to deflect said light beam parallel to an illuminating plane comprising the line of light emitting diodes so as to form a light beam having an ellipsoidal section.
