Abstract
The invention relates to a phosphor substrate, a light-emitting substrate, a lighting device, a method for manufacturing the phosphor substrate, and a method for manufacturing the light-emitting substrate. The phosphor substrate is a circuit board on one surface of which at least one electronic component is mounted, and is provided with an insulation substrate; a circuit pattern layer which is arranged on one surface of the insulation substrate, has a flat surface facing the outside of the insulation substrate in the thickness direction, and is bonded with a portion of the flat surface as at least one bonding surface bonded to the aforementioned at least one electronic component; a phosphor layer which is arranged on at least one non-bonding surface, which is at least an area on the aforementioned flat surface other than the aforementioned at least one bonding surface, and which contains phosphors which, when the light emitted by the at least one light-emitting element is the excitation light, have a light emission peak frequency in the visible range, wherein the phosphor layer is a laminate structure.
Description
technical field [0001] The present invention relates to a phosphor substrate, a light emitting substrate, a lighting device, a method for manufacturing the phosphor substrate, and a method for manufacturing the light emitting substrate. Background technique [0002] Patent Document 1 discloses an LED lighting fixture including a substrate on which a light emitting element (LED element) is mounted. The LED lighting fixture is provided with reflective material on the surface of the substrate to improve luminous efficiency. In addition, in the case of the structure disclosed in Patent Document 1, the reflective material cannot be used to adjust the light emitted by the LED lighting fixture to light of a light emission color different from the light emitted by the light emitting element. [0003] Patent Document 1: Chinese Patent Publication No. 106163113 [0004] However, the inventors of the present application have found that by providing a phosphor layer on a substrate, it...
