Title:
ILLUMINATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/085411
Kind Code:
A1
Abstract:
[Problem] To provide a flexible substrate in which the degree of decrease in brightness toward the terminal end thereof is small even when a product is long, and light emitting bodies do not become irregular in brightness even if the flexible substrate is cut, and an illumination apparatus using the flexible substrate. [Solution] Each of units comprises first conduction wiring that allows conduction between first outbound wiring and second inbound wiring via a first light emitting element, and second conduction wiring that allows conduction between first inbound wiring and the second inbound wiring via a second light emitting element. Electric power supplied from a leading end to the first outbound wiring is supplied to the first light emitting element by the first conduction wiring and circulated to the second inbound wiring in each of the units. Electric power supplied from the leading end to the second outbound wiring is circulated to the first inbound wiring in opposite direction via the first conduction part at the terminal end once, and thereafter in each of the units, is supplied to the second light emitting element by the second conduction wiring and circulated to the second inbound wiring.
