    摘要： A white LED includes a light emitting element with a light emission peak wavelength equal to or longer than 380 nm and equal to or shorter than 420 nm, and a phosphor layer containing three or more types of phosphors including at least a blue phosphor, a green phosphor, and a red phosphor and disposed in a manner to cover at least part of the light emitting element. The phosphor layer has a first phosphor layer and a second phosphor layer disposed in an opposite side of a side of the light emitting element of the first phosphor layer. In the first phosphor layer, a content of the blue phosphor in an entire phosphor contained in the first phosphor layer is equal to or less than 5 mass %, or the blue phosphor is not contained. In the second phosphor layer, a content of phosphor other than the blue phosphor in an entire phosphor contained in the second phosphor layer is equal to or less than 5 mass %, or no phosphor other than the blue phosphor is contained.

    摘要： Disclosed is a white LED lamp using an ultraviolet light emitting LED, which can simultaneously realize a high level of color rendering and a high level of brightness. Included is an LED chip 2 having a luminescence wavelength between 360 nm and 440nm, and a light emitting part excitable upon exposure to light from the LED chip 2 to emit white light and comprising a phosphor, the phosphor including blue, green, and red light emitting phosphors bonded to each other. A phosphor selected from europium-activated halophosphate phosphors and europium-activated aluminate phosphors is used as the blue light emitting phosphor. A gold- and aluminum-activated zinc sulfide phosphor is used as the green light emitting phosphor. A phosphor selected from europium- and samarium-activated lanthanum oxysulfide phosphors and copper- and manganese-activated zinc sulfide phosphors is used as the red light emitting phosphor.
