PROBLEM TO BE SOLVED: To provide an LED lighting lamp which attenuates light in a specific wavelength region and which can properly emit light in the wavelength regions other than that.SOLUTION: An LED lighting lamp A1 includes: an LED light-emitting part 2 including a plurality of LED chips; an elongated support member 1 for supporting the LED light-emitting part 2; a cylindrical translucent cover 3 for accommodating the LED light-emitting part 2 and the support member 1 and for transmitting the light from the LED light-emitting part 2; and a pair of bases 5 located on both ends of the support member 1. The LED light lamp A1 also includes a filter tube 6 which attenuates the light in one part of wavelength regions out of the light which has transmitted the translucent cover 3 and which is adhered to at least one part of the translucent cover 3 by thermal shrinkage. Between both ends of the translucent cover 3 and the pair of bases 5, a gap exists in an axial direction of the translucent cover 3. |
