The invention relates to an LED lamp having improved lighting efficiency, which is suitable in particular for work places in which low brightness tolerances are important. The LED workplace lamp is characterised by exactly defined illumination surfaces having exact edges that can additionally be built up in a modular manner and are able to restrict or extend the areas to be illuminated by means of zoom elements. The lamp and the lamp system are characterised in that the sources of radiation are LEDs, each of which is assigned at least one optical attachment for focussing and collecting the irradiated light, and that a Fresnel optical attachment is arranged on the light input side and aspherical lenses in a corresponding hexagonal construction are associated on the light output side. |
