Abstract

A fluorescent substrate (30) according to the present invention has a plurality of light emitting elements (20) mounted on one surface, and comprises: an insulation substrate (32); a first electrode group (34) positioned on one surface of the insulation substrate (32) and having a plurality of electrodes joined to the plurality of lighting elements (20); a fluorescent layer (36) positioned on one surface of the insulation substrate (32) and including a fluorescent material in which the emission peak wavelength when light emitted by the light-emitting elements (20) is used as excitation light is in the visible light region; and a second electrode group (38) positioned on the other surface of the insulation substrate (32) and having a plurality of electrodes.

Description

technical field [0001] The present invention relates to a phosphor substrate, a light emitting substrate, and a lighting device. Background technique [0002] Patent Document 1 discloses an LED lighting fixture including a substrate on which a light emitting element (LED element) is mounted. In the LED illuminating device, a reflective material is arranged on the surface of the substrate, so that the luminous efficiency is improved. [0003] Patent Document 1: Chinese Patent Publication No. 106163113 [0004] In the LED lighting device disclosed in Patent Document 1, it is inherently impossible to use a reflective material to adjust the light emitted by the LED lighting fixture to have a light emission color different from that emitted by the light emitting element. In addition, in Patent Document 1, the structure of the rear surface of the substrate is not clearly disclosed. Contents of the invention [0005] An object of the present invention is to provide a phosphor ...
