Light fixture

摘要

The invention shows and describes, among others, a light fixture (10) for illuminating building surfaces, comprising a circuit board (11) on which a plurality of LEDs (12a, 12b, 12c) are mounted, secondary optics (14) that bundle the light emitted by the LEDs, and tertiary optics (16) formed by a planar, translucent element that has light-directing microstructures.

主权项

1. A light fixture for illuminating building surfaces, the fixture comprising:
a circuit board; a plurality of LEDs mounted on the circuit board and emitting light; tertiary optics spaced from the circuit board and formed by a flat and translucent element having a face provided with a plurality of domed light-directing facets arranged in rows; and secondary optics formed by one or more lenses of cup-shaped section, each having totally reflective surfaces, between the LEDs on the circuit board and the tertiary optics, and each flared toward the tertiary optics such that the secondary optics totally transform all the light emitted by the LEDs into a single bundle of light beams all substantially parallel to one another and directed at a right angle against the tertiary optics.
