LIGHT EMITTING DEVICE AND METHOD FOR PRODUCING SAME |
摘要 |
A light emitting device 10 includes: a lead frame 12 a serving as a mounting portion having a cup 13 ; a light emitting element 14 , mounted on the bottom face 13 a of the cup, for emitting light having a predetermined peak wavelength; a layer of first phosphor particles 16 , absorbed and formed on the light emitting element, for absorbing light emitted from the light emitting element and for emitting light having a longer peak wavelength than that of the light emitted from the light emitting element; second phosphor particles 18 for absorbing at least one of light emitted from the first phosphor particles and light emitted from the light emitting element and for emitting light having a longer peak wavelength than that of the at least one of the light emitted from the first phosphor particles and the light emitted from the light emitting element; and a sealing member 20 , in which the second phosphor particles are dispersed, for sealing the light emitting element and the layer of first phosphor particles in the cup.
