Problems solved by technology

However, in known devices this can only be achieved by using multiple light sources aligned linearly with respect to each other and at different vertical distances from the optical deglare plate
However, such arrangements often generate defects in the generated patterns, where light sources closer to the deglare plate block light sources placed more distally, causing shadows in the generated light patterns

Embodiment Construction

[0056] The present invention provides a lighting device having a lens comprising a plurality of imaging regions each adapted to image a light source to generate a plurality of virtual light sources common to all imaging regions and along Spatial path distribution extending in a direction generally away from the lens. Each imaging region includes a plurality of sub-regions for focusing the input light source to a corresponding plurality of focal points common to all imaging regions. Focused light directed towards a focal point by each sub-region of the imaging area combines, such as to form a virtual light source at each focal point.

[0057] figure 1 A cross-sectional side view through an example lens 12 contained within a lighting device is schematically illustrated, in accordance with an embodiment of the present invention. figure 2 A closer cross-sectional view through a portion of the lens is shown. The lens has a light input surface 15 and a light output surface 18 . ...

Abstract

The invention provides a lens comprising a plurality of imaging regions, each adapted to image a light source to generate a plurality of virtual light sources common to all imaging regions and distributed along a spatial path extending in a direction generally away from the lens. Each imaging region comprises a plurality of sub-regions for focussing the input light source to a corresponding plurality of focal points common to the imaging regions. The focussed light directed to the focal points sub-regions of each imaging region combines so as to form at each focal point a virtual light source.An optical deglaring plate comprising an array of conical optical structures is used with the lens.

Description

technical field [0001] The invention relates to a lighting device comprising a lens for focusing a light source to a plurality of focal points. Background technique [0002] A recent development in the field of lighting has been that of "panel-type" lighting, in which interesting, often dynamic light effects are created across a layered front light output surface. These can be used, for example, for decorative effect, but also for functional purposes, such as displaying or conveying information. [0003] One way of providing such a device is by using a so-called "optical deglare", or, in a more specific example, a "conical deglare". The conical anti-glare plate is formed by a light-transmitting array of conical structures distributed on a support substrate. When the light spot is directed onto the surface of the anti-glare panel, the spot is converted by the optical structure of the panel into a corresponding ring light pattern, which is visible to the observer on the back...
