The invention discloses fluorescent powder used for an LED light source having insect repelling effect. The fluorescent powder used for the LED light source is a mixture of yellow and green fluorescent powder, amber fluorescent powder, and red fluorescent powder mixed according to a mass ratio of (15-25): (0.2-2): (1:3). The emission spectrum range of the fluorescent powder used for the LED light source is in a range from 490 to 850 nm under excitation of blue light having a wavelength in a range from 440 to 460 nm, and the main wavelength is in a range from 575 nm to 595 nm. The invention also discloses the LED light source having the insect repelling effect, and the LED light source comprises a substrate, a blue chip fixedly disposed at least one side of the substrate, and a fluorescent gel body disposed on the outer periphery of the blue light chip. The fluorescent gel body is the mixture of the fluorescent powder used for the LED light source and the silica gel mixed according to the mass ratio of (1-5): (3:7). The LED light source having the insect repelling effect is advantageous in that by adopting the optimized design of the fluorescent powder mixture, the light source having the mosquito repelling effect and the main optical wavelength in a range from 575 nm to 595 nm is acquired; the blue light spectrum is not provided, and therefore the oviposition of the insects is not facilitated, and the living environment of the insects are inhibited, and therefore the insect repelling is realized.
