Abstract:
An electric lamp, comprising:a light source (2) operable to emit a visible light; a light-transmitting lamp vessel (1) accommodating said light source (2) whereby the visible light propagates through said light-transmitting lamp vessel (1); and a light-absorbing coating (3) at least partially covering said light-transmitting lamp vessel (1) whereby the visible light propagates into said light-absorbing coating (3) from said light-transmitting lamp vessel (1), said light-absorbing coating (3) including an organically modified silane network, and a plurality of pigment particles dispersed through said organically modified silane network, said plurality of pigment particles including means for absorption characteristics absorbing a first portion of the visible light propagating through said light-absorbing coating (3) without generating a light scattering of a second portion of the visible light propagating through said light-absorbing coating (3).
