Abstract: Provided is a lighting source that includes a light-emitting diode and a fluorescent gel for packaging the light-emitting diode, the fluorescent gel having a phosphor and a silica gel composition mixed with the phosphor, the light-emitting diode is a blue light chip, and the phosphor includes a first red phosphor with a full width at half maximum of less than 60 nm and a second red phosphor with a full width at half maximum of more than 60 nm, the weight ratio of the first red phosphor to the second red phosphor is greater than 4:1, and the phosphor also includes at least one yellow or yellow-green phosphor, and an emission wavelength of the blue light chip is 420 nm to 480 nm.

Abstract: Provided is an LED assembly, an LED filament and an LED lamp, where the LED assembly has at least one first blue LED chip having a peak emission wavelength between 445 nm and 465 nm, at least one second blue LED chip having a peak emission wavelength between 465 and 480 nm, and the first blue LED chip and the second blue LED chip are combined to form an LED package, and a yellow-green phosphor having a peak emission wavelength between 510 nm and 535 nm, coated on the surface of the LED package. The peak emission wavelength of blue light of an LED assembly is dispersed within the ranges of 445 nm to 465 nm and 465 nm to 480 nm, and the peak intensity of the blue light is reduced within the two ranges.
