Abstract: A high performance luminaire having at least one lamp (1) and a reflector (2), partially surrounding the lamp (1), for focusing to a directed beam the light emitted by the lamp (1), the reflector (2) having an internal reflecting surface (3) which includes regions with different requirements because of being differently spaced from the lamp (1), permits an optimization of the reflector (2) during an optimization of its production costs by virtue of the fact that the reflector (2) comprises at least a first partial reflector (5) and a second partial reflector (6) which lie next to one another at an abutting edge (11), and whose reflecting surfaces (9, 10) together form the internal reflecting surface (3) of the reflector (2).

Abstract: In the measuring method for determining the effective light intensity of a pulsed LED light source, considering the physiology of the human eye, a light-sensitive detector measures a multiple pulse light signal emitted by the LED light source. Subsequently, the measured multiple pulse light signal is subjected to integration. The integration is effected on the basis of the form factor method.
