Embodiment Construction

[0054] Figures 1A-3B A perspective and cross-sectional view of a first embodiment of a lighting device 1 according to the invention is shown. The lighting device 1 comprises a support panel 2 on one side of which a light emitting module 3 (eg LED) is mounted. The support panel 2 has two opposite longitudinal sides 4,5 and two opposite transverse sides 6,7. The longitudinal sides 4, 5 extend in the direction of the arrow P1.

[0055] On the side of the support panel 2 in which the light emitting module 3 is mounted, the lighting device 1 comprises a reflective outer sheet 8 . The reflective outer sheet 8 is provided with a reflective layer 9 . The reflective layer 9 is guided towards the light emission module 3 . The reflective outer sheet 8 has first and second parallel longitudinal sides 11, 12 extending in the direction of arrow P1. Preferably, the reflective outer sheet 8 is opaque, thus preventing light from being emitted from this side of the lighting device 1 .

Abstract

A lighting device (1) comprising a support panel (2) located between two outer sheets (8, 10), which support panel is provided with at least one light emitting module (3), whilst at least one of the outer sheets (10) is translucent. The outer sheets are movable with respect to each other at least from a folded position in which the support panel and the outer sheets extend substantially parallel to each other and an unfolded position in which the outer sheets are at least partly further spaced apart than in the folded position. One of the outer sheets (8) is reflective, wherein, in the unfolded position of the lighting device, light emitted by the light emitting module towards the reflective outer sheet is reflected by the reflective outer sheet towards the translucent outer sheet through the support panel.

Description

technical field [0001] The invention relates to a lighting device comprising a support panel between two outer sheets provided with at least one light emission module, while at least one of the outer sheets is translucent, the outer sheet supporting at least the panel and the outer sheet therefrom The folded position extending generally parallel to each other and the unfolded position in which the outer panels are at least partially further spaced apart than in the folded position are movable relative to each other. Background technique [0002] Foldable lighting devices are in very wide use in many fields. [0003] WO2009 / 147657A2 shows a foldable lampshade suitable for inexpensive mass production and configured for easy assembly. The frame portion comprises a pair of joined or separated complementary sheet-like portions, each sheet-like portion being generally shaped as a mirror image of the other sheet-like portion. The sheet-like part is a sheet or foil, optionally wit...
