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.

摘要:
The present application is directed to an illumination device comprising a recycling cavity defined by recycling surfaces and a light emission surface; a light source within the cavity. A spectrum modifying layer is on a portion of the recycling surface, the spectrum modifying layer producing a spectral response different from the spectral response of the recycling surface. In some embodiments, the spectrum modifying layer shifts the spectral properties of the light being emitted from the light emission area from the spectral properties of the light source. In some embodiments, the spectrum modifying layer selectively absorbs a portion of light along the light source spectrum. In some embodiments, the spectrum modifying layer re-emits light at a wavelength longer than the wavelength it absorbed.
