LIGHT-EMITTING COMPONENT, PRINT HEAD AND IMAGE FORMING APPARATUS

Title:

LIGHT-EMITTING COMPONENT, PRINT HEAD AND IMAGE FORMING APPARATUS

Document Type and Number:

Japanese Patent JP2012174810

Kind Code:

A

Abstract:

To suppress generation of a stress in a pedestal on which a lens for extracting light efficiently is installed, in a light-emitting component having a light-emitting element array where multiple light-emitting surfaces are arranged in a row.

On the light-emitting thyristors L1, L2, L3...(opposite side of a substrate 80), spherical lenses 92 are provided, respectively, with cylindrical (round tubular) pedestals 91 interposed therebetween. The pedestal 91 is provided on the periphery of the light-emitting surface 311 of the light-emitting thyristor L1. Each lens 92 is provided through an air gap (air layer) 93 from each light-emitting surface 311 of the light-emitting thyristor L1, L2, L3...
