发明名称 Light emitting device having first and second wavelength converter parts
摘要 The light emitting device includes a light emitting element, a wavelength converter, and a light guider. The light emitting element has an element upper surface, an element lower surface, and an element side surface. The wavelength converter has a converter lower surface. The wavelength is provided to be connected to the light emitting element. The converter lower surface has an exposed region that does not face the element upper surface. The light guider guides light from the light emitting element to the wavelength converter. The light guider covers the element side surface and the exposed region. The wavelength converter includes first and second wavelength converter parts. The first wavelength converter part faces the element upper surface and has a first thickness. The second wavelength converter part does not face the element upper surface and has a second thickness thinner than the first thickness.

主权项 1. A light emitting device comprising: a light emitting element having an element upper surface, an element lower surface opposite to the element upper surface in a thickness direction of the light emitting element, and an element side surface between the element upper surface and the element lower surface; a wavelength converter having a converter lower surface and provided to be connected to the light emitting element such that the converter lower surface faces the element upper surface, the converter lower surface having an exposed region that does not face the element upper surface viewed along the thickness direction, the wavelength converter comprising: a first wavelength converter part facing the element upper surface viewed along the thickness direction and having a first thickness in the thickness direction; anda second wavelength converter part not facing the element upper surface viewed along the thickness direction and having a second thickness in the thickness direction, the second thickness being thinner than the first thickness; and a light guider to guide light from the light emitting element to the wavelength converter, the light guider covering the element side surface and the exposed region.
