Abstract
The invention relates to a matrix light source comprising a plurality of elementary light sources with light-emitting semiconductor elements, and a common substrate that is in contact with an integrated circuit. The integrated circuit is configured to delay, for a predetermined duration, the light-up of the elementary sources, upon receiving a light-up command.
Claims20
A matrix light source comprising an integrated circuit and a matrix array of lights with a first electroluminescent semiconductor element-based elementary light source and a second electroluminescent semiconductor element-based elementary light source, wherein the integrated circuit is in contact with the matrix array and further comprises, a delay unit which is functionally connected to the first and second elementary light sources and is configured so as to delay the activation of the second elementary light source by a predetermined period following the reception of an activation command.
A matrix light source comprising an integrated circuit and a matrix array of lights with a first electroluminescent semiconductor element-based elementary light source and a second electroluminescent semiconductor element-based elementary light source, wherein the integrated circuit is in contact with the matrix array and further comprises a delay unit which is configured so as to delay the activation of the elementary light source by a predetermined period following the reception of an activation command, and wherein the delay unit of each elementary light source of the set is functionally connected to the delay unit of another elementary light source of the set, the arrangement being such that the delay for the second elementary light source begins to elapse only once a delay of the first elementary light source has elapsed.
A matrix light source comprising an integrated circuit and a matrix array of lights with a first electroluminescent semiconductor element-based elementary light source and a second electroluminescent semiconductor element-based elementary light source, wherein the integrated circuit is in contact with the matrix array and further comprises delay units which is functionally connected to the first and second elementary light sources in sequence so as to form a chain and is configured so as to delay the activation of the second elementary light source by a predetermined period following the reception of an activation command.
