Zusammenfassung:	A filament lamp capable of emitting light uniformly belongs to the technical field of filament lamps. The LED bulb comprises a bulb shell, at least one group of double-color-temperature light bars, a core column support, a driving power supply and a lamp holder, wherein a first group of LED chips and a second group of LED chips on one double-color-temperature light bar are respectively coated with fluorescent glue with different color temperatures; and the first group of LED chips and the second group of LED chips are respectively and correspondingly coated with fluorescent glue with different color temperatures according to the fact that the polarities of the electrodes on the two sides of the other double-color-temperature lamp strip are the same as or opposite to the polarities of the electrodes on the two sides of one double-color-temperature lamp strip. The color temperatures of the two lamp strips in each group of double-color-temperature lamp strips are changed, or the LED chips of the two lamp strips
