Abstract
A recording head is described having mounted thereon M modules, each module comprising an array of N LEDs and associated drivers. The recording head comprises a carrier bar, and a carrier strip fixedly and electroconductively and thermoconductively secured to a surface of the carrier bar. The carrier strip comprises along one side thereof M spaced individual module carriers connected with the rest of said carrier strip by means of at least one frangible zone. M LED dies and associated driver module dies are fixedly secured to the surface of said M module carriers, each die containing an array of N linearly arranged LEDs. The array of N LEDs of each die overlaps the space between the spaced individual module carriers in order to come in abutting relationship with the end or ends of neighboring N LED arrays. In said LED array a module carrier on which a defective module is present can be replaced without damaging the adjacent modules.
