  • Publication number: 20220232700
    Abstract: A lighting device includes a light emitting element having element electrodes; a light guide member to receive incoming light from the light emitting element and to emit light spreading along a plane; and a substrate including a base substitute. Conductors are formed on a first surface of the base substrate. An adhesive member is formed on a second surface of the base substrate, and through-holes penetrating the substrate in a thickness direction of the substrate. The substrate is provided on the light emitting element via the adhesive member of the substrate such that a surface of the light emitting element is exposed through each of the through-holes to define a bottomed hole. Each of the element electrodes is connected to each of the conductors via a filler filling the bottomed hole. The filler has a lower surface than a surface carrying the conductors of the substrate in a cross-sectional view.

  • Patent number: 11363715
    Abstract: A lighting device including a light-emitter including light emitting elements, and a support having a first surface that carries a wiring line electrically connecting element electrodes of the light emitting elements and a light emitting surface, and a substrate including a base substrate, a conductor formed on a first surface of the base substrate, an adhesive member formed on a second surface of the base substrate, and a through-hole penetrating the substrate. A space is formed between the substrate and the light-emitter to communicate with a bottomed hole formed in a location of the through-hole as a result of adhering an adhesive surface of the adhesive member to a surface of the light-emitter having the wiring line formed thereon. The wiring line is connected to the conductor via a filler filling the bottomed hole, and the space is located outside an opening of the bottomed hole.
