Patent ID: 7626327

Claim:
A lighting apparatus capable of emitting white light, the lighting apparatus comprising: a module capable of emitting output light; a cord; and a controller portion connected to the module via the cord to supply electric power for driving the light emitting elements, wherein the module comprises: a first light emitting diode for emitting blue or bluish green light having a peak wavelength in a range of 480 nm to 510 nm; and a second light emitting diode for emitting red light having a peak wavelength in a range of 610 nm to 670 nm, wherein the controller portion controls electric current so as to output the light in which a range of wavelength 525 nm to 590 nm of a partial output light is not greater than ⅕ of the partial light output in a range of wavelength 380 nm to 780 nm corresponding to visible light components, and wherein the peak of the first light emitting diode is substantially greater than that of the second light emitting diode.
