Abstract
An LED lamp includes a substrate, an LED chip, and a resin portion. The LED chip is flip-chip bonded to the substrate. The resin portion covers the LED chip and includes at least one type of phosphor that transforms the emission of the LED chip into light having a longer wavelength than the emission. In this LED lamp, the resin portion has at least one side surface. The side surface is separated from another surface that can reflect the outgoing light of the resin portion, surrounds the side surfaces of the LED chip and is curved at least partially.
