The figure image symbolic display by the light-emitting diode light on the rotary body

摘要

Topic When the body turning at full speed even, offer the figure image symbolic display which it tries to be able to recognize logograph or character.SolutionsIt includes with the body of revolution printed circuit board and the spring one printed circuit board and the figure image symbolic printed circuit board, the aforementioned body of revolution printed circuit board installs the light-emitting diode in 1 strings at least, the aforementioned spring one printed circuit board installs the light-emitting diode in 1 strings at least, provides figure image symbolic area in the aforementioned figure image symbolic printed circuit board, joints between the spring piece and the light-emitting diode with the wire respectively, the aforementioned figure image symbolic printed circuit board connecting to all light-emitting diodes with the wire, forms the circuit, when the body turning at full speed, also the spring one printed circuit board following, turns to high speed,You trace the figure image symbolic area of the figure image symbolic printed circuit board and replace to the signal, transmit to the light-emitting diode of the aforementioned body of revolution printed circuit board. Choice figure Figure 2B
