Description [0020] Further description of the present invention will be made below with reference to the accompanying drawings and particular embodiments in order to facilitate a clearer understanding of the technical idea set forth in the present invention. [0021] Fig. 1 shows a light emitting diode lamp group of the present invention, which comprises at least two light source components 2 sequentially arranged along the height, two support conductive pillars 1 which are respectively and sequentially connected to the at least two light source components 2 and which are used for supporting light source components 2, and a drive circuit component 3 providing power to the at least two light source components 2, wherein the bottom ends of the two support conductive pillars 1 are both electrically connected to the drive circuit component 3, while the at least two light source components 2 achieve electrical connection via the support conductive pillars 1; said light source component 2 comprises a circuit board 21, a plurality of first LED lamp beads 22 electrically connected to the circuit board 21 and arranged around the circumference of the centerline of the circuit board 21 at regular intervals, and a plurality of second LED lamp beads 23 electrically connected to the circuit board 21 and arranged around the circumference of the centerline of the circuit board 21 at regular intervals; the length of a pin of said first LED lamp bead 22 is greater than that of a pin of the second LED lamp bead 23, so that the distance between the luminous body of the first LED lamp bead 22 and the circuit board 21 is greater than that between the luminous body of the second LED lamp bead 23 and the circuit board 21; and all pins of the plurality of first LED lamp beads 22 and second LED lamp beads 23 are provided on the circuit board 21 in an inclined way. Specifically, the top ends of said first LED lamp beads 22 and second LED lamp beads 23 all incline away from the centerline of the circuit board 21, so that the light rays of the light emitting diode lamp group incline outwardly to achieve 360-degree full irradiation. Therefore, during use, the second LED lamp beads 23 can be used to illuminate a lower area above the circuit board 21, and the first LED lamp beads 22 can be used to -6 illuminate a higher area above the circuit board 21, thus ensuring the brightness of the lower area and the higher area above the circuit board 21, and further avoiding the formation of an apparent dark region in the lower area or the higher area; and moreover, by connecting the first LED lamp beads 22 and the second LED lamp bead 23 on the same group of light source components 2 to the same circuit board 21, the number of circuit boards 21 can be minimized to the largest extent, and the purpose of material saving can be achieved; and furthermore, the combined design of the first LED lamp beads 22 and the second LED lamp beads 23 can also improve esthetics, and add decorative and esthetic effect. And a support conductive pillar 1 can not only achieve electrical connection of the at least two light source components 2, but also play a supporting role, and attain the purpose of material saving and cost reduction. [0022] The circuit boards 21 of the at least two light source components 2 are parallel to each other; and the centerlines of the circuit boards 21 of the at least two light source components 2 are overlapped. The inclination angles of the pins of the plurality of second LED lamp beads 23 located on the same circuit board 21 are the same, and the inclination angles of the pins of the plurality of first LED lamp beads 22 located on the same circuit board 21 are the same. [0023] The light emitting diode lamp group preferably comprises at least two light source components 2 sequentially arranged along the height.

[0024] Naturally, the number of said light source components 2 can also be set to more than just two according to actual demand, but limiting the number of the light source components 2 to two is the optimal solution of the present utility model, which in addition to ensuring the illumination brightness of the light emitting diode lamp group may also control costs more effectively at the same time. [0025] In order to facilitate the installation of the drive circuit component 3, the light emitting diode lamp group also comprises a mounting base, in which said drive circuit component 3 is located.
