| titleOfInvention | White light emitting lamp, and white light led lighting device equipped with same |
| abstract | An object is to provide a white light emitting lamp 1 comprising: a semiconductor light emitting element 2 which is placed on a board 3 and emits ultraviolet light or blue light; and a light emitting portion that is formed so as to cover a light emitting surface of the semiconductor light emitting element 2, the light emitting portion containing a blue phosphor B, a green phosphor G, a red phosphor R and a deep red phosphor DR that are excited by the light emitted from the semiconductor light emitting element 2 to respectively emit blue light, green light, red light and a deep red light, the white light emitting lamp 1 emitting white light by mixing light emission colors from the blue phosphor B, the green phosphor G, the red phosphor R and a deep red phosphor DR with one another, wherein the deep red phosphor DR has a main emission peak in a longer wavelength region than a main emission peak of the red phosphor, the red phosphor R comprises at least one component selected from: a europium-activated SiAlON phosphor and a europium-activated CASN phosphor each having a predetermined composition, while the deep red phosphor DR comprises a manganese-activated magnesium florogermanate phosphor having a predetermined composition. According to the above white light emitting lamp, when the BGR phosphor is used in combination with the semiconductor element such as an LED or the like, and a deep red phosphor DR having a predetermined composition is further added in addition to the red phosphor R, so that luminance characteristics can be improved, whereby there can be provided a white light emitting lamp excellent in both high luminance and high color rendering properties. |
