LED LIGHT EMISSION CONTROL DEVICE |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide an LED light emission control device capable of achieving an emission having a fluctuation closer to nature (for example, a fluctuation of a candle flame) in LED light emission control. <P>SOLUTION: An LED light emission control device comprises: luminance data holding means 110 for holding digital data representing a luminance of light; luminance data reading means for sequentially reading the digital data; ΔΣ processing means 120 for performing ΔΣ processing for the read digital data with a program operating on a microcomputer; high-frequency noise removal means for removing a high-frequency noise from the data demodulated by the ΔΣ processing means 120; and LED light emission means for causing the LED to emit light based on the data from which the high-frequency noise is removed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
