LED LIGHT-EMITTING DEVICE AND MANUFACTURE OF LIGHT-EMITTING BLOCK USED IN THE SAME DEVICE

摘要

PURPOSE:To enhance productivity by a method wherein a light-emitting block where a plurality of LED chips and a plurality of lead-pin pairs are united is piled up on a lend block and an LED lamp aggregate is constituted equivalently in order to make a selection at a stage of a chip and to avoid a selection at a stage of an LED lamp. CONSTITUTION:As a light-emitting block 10, a plurality of LED chips 14 and a plurality of lead pins 15a, 15b for electricity supply use are united by using a resin layer 16. When a substrate 11 for electricity supply use is piled up on its rear, all the plural lead pins 15a, 15b can be pierced collectively through corresponding component-mounting holes 11a; productivity can be enhanced. A lend block 12 where a plurality of condensing lenses 12a have been arranged is fixed to the surface of the light-emitting block 10; an LED aggregate is constituted. Thereby; a selection at a stage of LED chips can be executed when high-brightness light-emitting is required.
