Aminosilane is included in order to stabilize the pigments.
摘要:
The present invention relates to a light-emitting device comprising at least one light-emitting diode (LED) chip (12), and an inorganic optical element (14) being connected to the chip(s) by means of a bond (16). The light-emitting device is characterized in that the bond is of a bonding material comprising a matrix including silicon and oxygen atoms with hydrocarbon groups directly bonded to at least a fraction of the silicon atoms. Such inorganic-organic bonding material has very high photo and thermal stability. As a result, high power and high lumen LED chips can be deployed, whereby high brightness light-emitting devices can be realized. The present invention also relates to a method for the manufacture of such light-emitting device.
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.
