Abrégé
(EN)
Disclosed is a light-transmitting substrate that is at least partly provided with a light-absorbing coating. Said coating comprises silver or gold particles that are incorporated in a sol-gel matrix. In order to improve the transmittance in red and to reduce the amount of silver and gold particles, a blue-absorbing compound is added to the coating. Furthermore, an electric lamp is disclosed, said lamp comprising a light-transmitting lamp vessel that accommodates a light source. Said lamp vessel comprises the above light-transmitting substrate. Moreover, a light-absorbing coating is disclosed.
(FR)
L'invention concerne un substrat à transmission de lumière qui est muni, au moins en partie, d'un revêtement absorbant la lumière. Ledit revêtement comprend des particules d'or ou d'argent incorporées à une matrice sol-gel. Afin d'améliorer la capacité de transmission en rouge et de réduire la quantité de particules d'or ou d'argent, on a ajouté au revêtement un composé absorbant les bleus. En outre, l'invention concerne une lampe électrique, ladite lampe comprenant un bulbe de lampe à transmission de lumière qui comprend une source lumineuse. Ce bulbe de lampe comprend ledit substrat à transmission de lumière. En outre, l'invention concerne un revêtement absorbant la lumière.
