Lighting device
First Claim
1. A lighting device, comprising:
- a substrate having a first side and a second side; and
a plurality of lighting elements mounted on the first side of the substrate,wherein the substrate comprises a plurality of electrically conductive first thread elements and plurality of electrically insulating second thread elements, wherein the plurality of electrically conductive first thread elements and plurality of electrically insulating second thread elements are interwoven together, each of the first and second thread elements including a first side disposed at the first side of the substrate, and a second side disposed at the second side of the substrate,wherein at least some of the electrically conductive first thread elements each comprise a yarn having a first reflective coating provided on and cladding at least one of the first side and the second side thereof for reflecting ambient light,wherein at least some of the electrically insulating second thread elements each comprise a yarn having a second reflective coating provided on and cladding at least one of the first side and the second side thereof for reflecting ambient light,wherein the first reflective coating comprises a metallic material and the second reflective coating comprises an insulating material different than the first reflective coating material, andwherein each of the lighting elements is electrically connected between two of the electrically conductive first thread elements so as to be configured to be supplied electrical current by the electrically conductive first thread elements and in response thereto to emit an artificial light.

Abstract
A shading device for a greenhouse includes a shading element and at least one lighting element, wherein the shading element comprises an outer side and an inner side. The shading element is formed from interwoven electrically conductive first thread elements and electrically insulating second thread elements. The first and/or second thread elements each may be adapted for reflecting an ambient light. The lighting element(s) may be arranged at the inner side of the shading element and connected with the first thread elements, and the lighting element(s) may be driven by an electrical current, conducted by the first thread elements, resulting in the emission of an artificial light, which may illuminate a plant growing in the greenhouse.
