Abstract
Official abstract text for this publication.
A light emitting module includes a substrate, a light reflective resin layer, wiring electrodes and a light emitting element. The light reflective resin layer is arranged on the substrate. The wiring electrodes are arranged over the substrate with the light reflective resin layer being interposed between the substrate and the wiring electrodes. The light emitting element has an electrode formation surface including a positive and negative pair of element electrodes, and a light emitting surface on a side opposite to the electrode formation surface. The light emitting element is arranged on top surfaces of the wiring electrodes with the element electrodes facing the top surfaces of the wiring electrodes.
First claim
Opening claim text (preview).
What is claimed is: 1. A light emitting module comprising: a substrate; a light reflective resin layer arranged on the substrate; wiring electrodes arranged over the light reflective resin layer so that the light reflective resin layer is arranged between the substrate and the wiring electrodes, the light reflective resin layer overlapping the wiring electrodes in a plan view; and a light emitting element having an electrode formation surface including a positive and negative pair of element electrodes, and a light emitting surface on a side opposite to the electrode formation surface, the light emitting element being arranged on top surfaces of the wiring electrodes with the element electrodes facing the top surfaces of the wiring electrodes, wherein the light reflective resin layer and the wiring electrodes are arranged between the light emitting element and the substrate. 2. The light emitting module of claim 1 , further comprising a light reflective member arranged on the light reflective resin layer and the wiring electrodes, and surrounding the light emitting element. 3. The light emitting module of claim 2 , wherein the light reflective member covers the electrode formation surface and a side surface of the light emitting element. 4. The light emitting module of claim 1 , wherein the light reflective resin layer covers side surfaces of the wiring electrodes. 5. The light emitting module of claim 1 , wherein the top surfaces of the wiring electrodes and a top surface of the light reflective resin layer surrounding the wiring electrodes are formed on the same plane. 6. The light emitting module of claim 4 , wherein the top surfaces of the wiring electrodes and a top surface of the light reflective resin layer surrounding the wiring electrodes are formed on the same plane. 7. The light emitting module of claim 1 , wherein the wiring electrodes are made of a material containing at least one item selected from the group consisting of Cu, Au and Al. 8. The light emitting module of claim 1 , wherein surfaces of the wiring electrodes on a substrate side are configured by a material containing at least one item selected from the group consisting of Al, Ag, Pt, and Rh. 9. The light emitting module of claim 1 , further comprising a light transmissive member arranged above the light emitting element. 10. The light emitting module of claim 9 , further comprising a wavelength conversion member arranged on a top surface of the light transmissive member. 11. The light emitting module of claim 1 , further comprising a plurality of light emitting elements spaced apart from each other, and the wiring electrodes electrically connect the element electrodes of the plurality of light emitting elements. 12. The light emitting module of claim 10 , further comprising a plurality of light emitting elements placed with a designated interval open, and the wiring electrodes electrically connect the element electrodes of the plurality of light emitting elements. 13. The light emitting module of claim 12 , wherein the plurality of light emitting elements are covered by the wavelength conversion member and the light transmissive member.
