The present disclosure is generally directed to illumination devices, and particularly directed to illumination devices utilizing light transmissive layers and methods for making the same. An illumination device and method for making the device are disclosed. The device, in particular, includes a substrate and conductive region disposed on the substrate. One or more light sources, such as LEDs, are disposed on a surface of the substrate and electrically coupled to the electrically conductive region for supply of electric current. The device also includes one or more light transmissive layers disposed on the substrate and the at least one light source to encapsulate light sources and also to control characteristics of light delivery from the light sources as light passes through the light transmissive layers.

Cette invention concerne, d'une manière générale, des dispositifs d~éclairage, et plus particulièrement, des dispositifs d'éclairage utilisant des couches permettant le passage de la lumière, ainsi que des procédés permettant de les réaliser. Cette invention concerne un dispositif d'éclairage et un procédé permettant de réaliser ce dispositif. Le dispositif, plus particulièrement, comprend un substrat et une zone conductrice disposée sur le substrat. Une ou plusieurs sources de lumière, telles que des DEL sont disposées sur une surface du substrat et elles sont électriquement couplées à la zone électroconductrice afin de fournir un courant électrique. Le dispositif comprend également une ou plusieurs couches permettant le passage de la lumière, lesquelles couches sont disposées sur le substrat et sur la ou les sources de lumière de manière à encapsuler les sources de lumière et également afin de réguler les caractéristiques de la diffusion de lumière provenant des sources de lumière alors que la lumière passe à travers les couches permettant le passage de la lumière.
