Beschreibung
Zusammenfassung:	The invention provides a color-temperature-variable LED streetlamp. The LED streetlamp is characterized in that the LED streetlamp uses a plurality of double-color-temperature LED lamp beads as the light sources, and the double-color-temperature LED lamp beads are regularly arranged on the light-emitting face of the streetlamp; each LED lamp bead comprises a light distribution lens on the light-emitting face of the lamp bead and an even number of LED light-emitting chips, half of the LED light-emitting chips are cold-color-temperature LED light-emitting chips, and the other half of the LED light-emitting chips are warm-color-temperature LED light-emitting chips; the working states of the cold-color-temperature LED light-emitting chips and the warm-color-temperature LED light-emitting chips are mutually exclusive to allow the light-emitting color temperature of the double-color-temperature LED lamp beads to be switched between cold color temperature and warm color temperature; the LED streetlamp is provided wi
