WHITE LIGHT-EMITTING LAMP FOR ILLUMINATION AND ILLUMINATING DEVICE USING THE SAME

摘要

A white light emitting lamp 1 includes a phosphor layer 5 which emits white light by being excited by light emitted from a semiconductor light emitting element 2. A transparent resin layer 4 is interposed between the semiconductor light emitting element 2 and the phosphor layer 5. The phosphor layer 5 contains, as a green phosphor, a rare earth borate phosphor activated by trivalent cerium and terbium.
