Detailed ways

The utility model provides an LED lamp group, which can present multiple different shapes, colors and special lighting effects at the same time after being powered by a power supply.

Please refer to FIG. 1 to FIG. 4 , which are a preferred feasible embodiment of the LED lamp set of the present invention. Each LED lamp in the LED lamp group can adopt two-legged LED lamps or multiple-legged LED lamps. For the convenience of description, this embodiment only uses two-legged LED lamps as an example to give a detailed description.

The LED lamp set includes a lamp holder 1, a circuit board 2, a lampshade 3, a plurality of LED lamps 4 arranged inside the lamp holder, at least one LED lamp 5 arranged outside the lamp holder, several wires 6 and at least one wire 7. The circuit board 2 is fastened in the lamp holder 1 , the lampshade is fastened on the lamp holder, and the wire 6 connects the LED lamp 5 arranged outside the lamp holder with the circuit board 2 .

The lamp holder 1 includes two elastic arms 11 and two notches 12 . The elastic arms 11 are formed by extending upward from the periphery of the circular bottom of the lamp holder 1 , and a gap 12 is formed at a space between every two elastic arms 11 .
