A reflector element and a method for manufacturing a reflector element are disclosed. In an embodiment the reflector element includes a plastic substrate and a silver layer arranged on the plastic substrate. The reflector element further includes a first barrier layer arranged on the silver layer, wherein the barrier layer has an at least 15 nm-thick oxide layer and a second barrier layer arranged on the first barrier layer, wherein the barrier layer includes siloxane, and wherein a thickness of the second barrier layer is at least 250 nm and at most 450 nm.

Reflector element and a method for manufacturing same

A lamp includes a transparent envelope having a first region defining an enclosed interior volume and a closure region adjacent to the first region, a light source in the interior volume and electrically coupled through the closure region, an interference filter coating on the exterior of the first region, and a light absorbing coating that is 7&#x2013;40 nanometers thick on the exterior of the first region, except in a ring-shaped portion adjacent to the closure region that has a thickness of 50&#x2013;200 nanometers.

Lamp that emits colored light

The invention relates to an incandescent lamp whose lamp vessel ( ) has an interference filter ( ) with locally differing layer thickness for producing red light. The interference filter ( ) has a second absorber layer and additional layers of low optical refraction and high optical refraction for reducing its transmission in the violet, blue and green spectral regions.
