Embodiment
Further to illustrate the present invention to reach the technological means and effect that predetermined goal of the invention is taken, below in conjunction with Accompanying drawing and preferred embodiment, to proposing embodiment, structure, feature and its effect according to the present invention, describe in detail as after.
Fig. 1 show the lamp of more LED lamp beads of first embodiment of the invention and the structure composition of light-emitting diode display.Refer to The lamp and light-emitting diode display of more LED lamp beads shown in Fig. 1, Fig. 1 have the first via L1 that can be separately controlled, the second road L2, the 3rd Road L3, the 4th road L4, the 5th road L5, the 6th road L6, totally 6 paths of LEDs lamp bead, and main line E1, the main line electrically connected with control circuit E2, main line E3.
First via L1 LED lamp bead positive wire electrically connects with the second road L2 LED lamp bead negative wire, first via L1's The electrical connection of LED lamp bead negative wire and the second road L2 LED lamp bead positive wire, form the first two-way LED lamp bead unit C1. 3rd road L3 and the 4th road L4, the 5th road L5 and the 6th road L6 are separately constituted and the first two-way LED lamp bead unit C1 identicals Two two-way LED lamp bead unit C2, the 3rd two-way LED lamp bead unit C3.
In order to distinguish the two-way lamp bead direction in two-way LED lamp bead unit, two-way lamp bead is divided into by direction in figure Upper paths of LEDs lamp bead (corresponding odd number road) and lower paths of LEDs lamp bead (corresponding even number road).Upper paths of LEDs lamp bead positive wire and lower paths of LEDs Lamp bead negative wire is electrically connected and electrically connected with a main line, the LED lamp bead negative wire on upper road and the LED lamp bead positive pole on lower road The electrical connection of lead simultaneously electrically connects with another main line
