Paper Abstract

Applications requiring high lumen packages are traditional the domain of light sources like discharge lamps. Currently, LEDs make their way into such applications. LED street lighting projects, which are regularly covered in the press, provide a case of point. Life time and luminous efficacy are considered as being the main advantages of LEDs. Nonetheless, other current light sources for street lighting have similar performance. Analysing a street-lamp as a complete system, we can show that LED solutions have significant advantages if highly efficient optics are used. We present an example with tailored free-form optics. These make efficient use of the valuable LED light by exactly redistributing it into the desired illuminance pattern.
