LED LINEAR LED ARRAY FOR DIGITAL PRINTING APPARATUS

摘要

An array 200 of light emitting semiconductor components for use in a digital printing device, each light emitting semiconductor component comprising a driver 220 and one or more light emitting devices 210, the array 200 being the first of the light emitting semiconductor components. A data bus (D ₀ , D ₁ , D ₂ , D ₃ ) connected to the first subset of light emitting semiconductor components forming a partition, the array 200 also forming a second partition of the light emitting semiconductor component An auxiliary bus A ₀ , A ₁ , A ₂ , A ₃ connected to a second subset of light emitting semiconductor components, wherein the first and second partitions each have a light emitting semiconductor component to which they belong. Selected to be uniquely identified by the subset of the first partition and the subset of the second partition, the data bus D ₀ , D ₁ , D ₂ , D ₃ instructing the first subset of light emitting semiconductor components. Each light emitting semiconductor component is configured to supply Provides an array of light emitting semiconductor components, configured to extract instructions based on their membership to a particular subset according to the second partition.
