Abstract
An illumination unit includes a thin and flexible substrate and flexible electrical tracks formed on the flexible substrate. A number of solid-state light generating sources are arranged on the flexible substrate along the electrical tracks and are electrically connected to the electrical tracks. A flexible and optically transparent encapsulant is provided to encapsulate the light generating sources on the substrate such that the illumination unit is both thin and flexible.
Claims21
An illumination unit, comprising:
- a thin and flexible substrate;
- a plurality of flexible electrical tracks formed on the flexible substrate;
- a plurality of solid-state light source packages arranged on the flexible substrate along the electrical tracks and being electrically connected to the electrical tracks, the light source packages having light generating sources, each light source package having at least one light generating source to generate light, a reflector cup to reflect the light, and an optically designed shape to channel out the light at a predetermined viewing angle;
- and
- a flexible and optically transparent encapsulant to encapsulate the light generating sources on the substrate without leaving any void such that the illumination unit is both thin and flexible.
