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

摘要

Disclosed is a white light-emitting lamp (1) comprising a phosphor layer (5) which emits white light when excited by the 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 a rare earth borate phosphor activated by trivalent cerium and terbium as a green phosphor.
