Document Type and Number:

WIPO Patent Application WO/2022/139175

Kind Code:

A1

Abstract:

Lighting using low-illuminance photocells, of the present invention, comprises: a plurality of battery cells, which are each formed as a planar structure and are arranged into a polyhedral structure, and absorb low-illuminance light to generate electricity; a plurality of pillars located at the edges of the polyhedral structure and interposed between the battery cells; a light-emitting body located at the front of both bottom surfaces of the polyhedral structure; and a power supply unit which charges electricity generated by the battery cells and supplies same to the light-emitting body, wherein each of the battery cells includes an inner portion fitted between the pillars, and an outer portion provided outside the inner portion and formed longer than the inner portion, on both sides along a circumferential direction of the polyhedral structure so as to cover the pillar, an electrode terminal closely abutting on the pillar is provided at an edge of the outer portion, and the plurality of pillars are provided with a conductive portion which is connected to the electrode terminal and conducts electricity.
