摘要:
Indoor tanning, especially in commercial establishments which provide tanning beds, has been a very popular endeavour for the last few decades, particularly in view of concerns for exposure to natural sunlight and ultra-violet (UV) light. The invention relates to an improved tanning apparatus, having multiple light sources (6a, 6b), filtering means (8a, 8b) and reflecting means (9a, 9b).

A luminaire for illuminating a space underneath a ceiling or a canopy (1) to which the luminaire (2,3) is attached. The luminaire (2,3) comprises a plurality of LEDs (31) positioned in a straight array, and an elongated convergent lens (30) which extends parallel to the array of LEDs (30). The array of LEDs (30) is located at a distance (D) from the plane of symmetry (33) of the elongated lens (30).

A lighting unit (1), comprising a bowl shaped reflector (6), and a plurality of point shaped light sources (2) arranged inside the reflector. The unit further comprises a mixing chamber (4) in which the point shaped light sources (2) are arranged, and a scattering layer (5) covering the mixing chamber (4). The scattering layer (5) is partially reflecting and partially transmitting, thereby ensuring that light emitted by the point shaped light sources (2) is mixed in the mixing chamber (4) before reaching the reflector.This allows light emitted from the mixing chamber via the reflector to be conceived as one beam. In use, light from the point shaped light sources may be reflected by the scattering layer and then scattered by the scattering layer so that the reflector generates a beam similar to a halogen beam.

This invention relates to a light emitting device (100) having a movable collimating unit for adjusting the output direction of light being emitted from the light emitting device. The light emitting device comprises a base unit (110), and a light output unit (120) which is engaged with the base unit. The light output unit comprises at least one light source (121) for emitting light. The light emitting device further comprises a movably arranged collimating unit (130) for adjusting the direction of the emitted light, which is arranged such that it encompasses a light output portion (125), which is arranged on the light output unit.

The invention relates to a lighting device (10) with a light emitter (1) that comprises OLEDs of at least two different primary colors. The light emitter (1) is followed by a primary optics, e.g. a collimator (13) or a lens, and by a tapered tubular reflector (14) with a diameter (d) that increases from its narrow end to its wide end. The light emitter (1) may particularly be composed of concentric rings of different OLEDs.

An illumination system has linear array of light emitters (R,G,B,A,W) associated with it least one linear array of outcoupling means (O1,O2,O3, . . . ) for coupling light out of the illumination system. Each linear array of outcoupling means is arranged parallel to the linear array of light emitters. For each linear array of outcoupling means, a configuration of the outcoupling means and a configuration of the light emitters fulfill the requirement: NCU×NLC=NOU×NLO, wherein NCU is the number of clusters (C1,C2,C3, . . . ) per unit (U1, . . . ), NLC is the number of light emitters in each of the clusters, NOU is the number of outcoupling means per unit, NLO is the number of light emitters per outcoupling means. A “cluster” is the smallest repetitive collection of light emitters forming the linear array of light emitters. A “unit” is the smallest number of adjacent clusters repetitive with respect to the outcoupling means and with respect to the light emitters.
