Patent ID: 7935975

Claim:
A white LED lamp comprising a light emitting diode having a luminescence wavelength of not less than 360 nm and not more than 440 nm, and a light emitting part excitable upon exposure to light from the light emitting diode to emit white light and comprising a blue light emitting phosphor, a green light emitting phosphor, and a red light emitting phosphor, wherein the blue light emitting phosphor comprises at least one phosphor selected from europium-activated halophosphate phosphors and europium-activated aluminate phosphors, the red light emitting phosphor comprises at least one phosphor selected from europium- and samarium-activated lanthanum oxysulfide phosphors and copper- and manganese-activated zinc sulfide phosphors, and the green light emitting phosphor comprises a gold- and aluminum-activated zinc sulfide phosphor having a composition represented by general formula ZnS:Au x ,Al y wherein x and y are numbers satisfying 0.0002≦x≦0.0015 and 0.0001≦y ≦0.0012, respectively, and the blue light emitting phosphor, the green light emitting phosphor, and the red light emitting phosphor have previously been bonded to one another with a binder.
