Abstract:
Provided are a lighting device in which adjacent lighting appliances appears continuous with inconspicuous joint therebetween, and a method for constructing a building.
Each of a first lighting appliance and a second lighting appliance includes a lighting appliance body including a chassis, and a plurality of light sources, a fitting adapter disposed on the rear surface of the chassis, the fitting adapter being fitted into a mounting hole formed in a building material, and a light-transmissive cover.
The first lighting appliance and the second lighting appliance are arranged adjacent to each other with respective corresponding ones of the lateral surface portions abutting against each other,
The first lighting appliance includes a first coupling member disposed on the rear surface of the chassis, and the second lighting appliance includes a second coupling member disposed on the rear surface of the chassis.
The first coupling member and the second coupling member are coupled on the rear surface with the first lighting appliance and the second lighting appliance adjacent to each other with the respective corresponding ones of the lateral surface portions abutting against each other.

Application number: 17/544,129

Abstract:
A method of manufacturing a light emitting device includes: providing a light emitting element comprising: a semiconductor laminate having a first surface, a second surface, and a lateral surface between the first and second surfaces, and an electrode disposed at the second surface; disposing a resin layer in an A-stage state on a support; placing the light emitting element on an upper surface of the resin layer while the upper surface of the resin layer and the first surface of the semiconductor laminate face each other; heating the resin layer at a first temperature to reduce a viscosity of the resin layer and causing the light emitting element to sink due to its own weight such that the second surface of the semiconductor laminate is exposed; and curing the resin layer by heating the resin layer at a second temperature higher than the first temperature, thereby forming a resin member.
