US 2015/0176783 A1 · COLUMNAR LIGHT EMITTING DEVICE AND MANUFACTURING METHOD OF THE SAME

Abstract

The device bends readily and safely without a sealing resin peeling off or a breakage in a wire. In an LED columnar light emitting device 1 in which a plurality of two conductive regions 2 and 3 corresponding to the ± polarities are provided in the columnar direction on a film wiring board, each light emitting element is connected to and installed on the plurality of two conductive regions 2 and 3, and each LED chip 6, as each light emitting element, is sealed above with a transparent sealing resin 8, notch sections 9 and 9A are formed on both outer sides of two plated lines 4 as opening sections between the two conductive regions 2 and 3 and another two conductive regions 2 and 3 adjacent thereto in the columnar direction.
