    摘要: The electric lamp comprises a lamp vessel (1) which is transparent to visible light and which accommodates a light source. At least a part of the lamp vessel (1) is covered with a light-absorbing coating (3). According to the invention, the light-absorbing coating (3) comprises a network which can be obtained by conversion of an organically modified silane by a sol-gel process. The organically modified silane is selected from the group formed by compounds of structural formula R′Si(OR″)3, wherein R′ is an alkyl or aryl group and R″ is an alkyl group. Preferably, R′ is CH3 or C6H5 and R″ is CH3 or C2H5. Nano-sized silica particles having a diameter d≦50 nm may be incorporated in the network. The pigment is preferably chosen from the group formed by Fe2O3, P-doped Fe2O3, ZnFe2O4, ZnO.Fe2O4, CoAl2O4, Nd2O5, BiVO4 and zirconium praseodymium silicate or mixtures thereof. The light-absorbing coating (3) of the electric lamp according to the invention is optically transparent, substantially free of scattering and stable at temperatures up to 350° C.
