Title:
LED SUBSTRATE AND LIGHT IRRADIATION APPARATUS HAVING THE LED SUBSTRATE
Document Type and Number:
Japanese Patent JP2017188489
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an LED substrate having no directivity and capable of being easily replaced while including many LED elements.SOLUTION: An LED substrate includes: a rectangular substrate 121 having sides in a first direction and a second direction; a plurality of LED elements 125 arranged on a surface of the substrate; and a plurality of conductive members for electrically connecting the plurality of LED elements on the surface of the substrate and forming 2n (n is an integer of 1 or more) circuits mutually independent in the first direction. Each circuit has a first electrode section electrically connected to the external and allowing inflow of a current from the external on the conductive member connected to one terminal of the circuit and a second electrode section electrically connected to the external and outputting a current to the external on the conductive member connected to the other end of the circuit, and the first electrode section and the second electrode section are opposed to each other in the second direction and are alternately arranged in the first direction so as to be located point-symmetrically about the center of the substrate to be a symmetrical point.SELECTED DRAWING: Figure 3
