Embodiment Construction

[0042] according to Figures 1 to 3b One embodiment of a lamp arranged as a street light is shown. The LED 1 is arranged on a carrier, in particular a PCB (prited circuit board, printed circuit board) 5 , and is fixedly mounted in a lamp housing (not shown). Arranged above the LEDs is a freeform lens 2 made of glass or of a transparent plastic, such as PMMA, PU or silicone. The LED 1 is arranged in the cavity 10 of the freeform lens 2 . Chamber 10 as Figure 2a with 3a The shown has a convex geometry, which has the result that the light of LED1 is refracted as shown by the rays L1 , L2 and L3 . The freeform lens 2 is mounted movably relative to the PCB 5 with the lens 1 . The direction 4 of the movement motion lies in the C90 / 270 plane of the lamp.

[0043] Different light distributions are produced by the movement of the freeform lens 2 relative to the LED 1 . The illustrated embodiment is particularly intended for generating light distributions for street lighting. T...

Abstract

The invention relates to an internal or outdoor luminaire, in particular a street lamp, having at least one LED serving as a light source and at least one free-molded lens corresponding to the LED so as to be used for influencing distirubtion of light emitted by the luminaire, wherein free-molded lenses are non-rotationally symmetric, the free-molded lenses and the LEDses can move between at least one first position and second position through relative motion, the relative motion at least partially includes motion vertical to a main radiation direction of the LED, and the free-molded lenses generate differente light distribution in the first position and the second position.

Description

technical field [0001] The invention relates to a lamp for stationary interior or exterior lighting, in particular a street lamp (Strassenleuchte), having at least one LED (light-emitting diode, which can also be understood as OLED, organic light-emitting diode) and a corresponding LED Freeform lenses. Background technique [0002] For the lighting of interior and exterior areas, especially for street lights, a plurality of LEDs are used as lighting means due to the advantages in terms of energy saving and lifetime. Compared to conventional lighting devices, approximately point-shaped light sources require modified optical arrangements in order to achieve the desired light distribution of the lamp for a given application. [0003] Reflector technology is also used in LEDs, as in conventional lighting devices. In this case, the point-shaped light projections of the LEDs, which can be arranged in a combined array (Array), are distributed on the surface of the reflector. The...
