LIGHTING SYSTEM |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a lighting system whereby an infrared ray signal is surely transmitted to a luminaire even when the infrared ray signal from a remote- control transmitter is transmitted in any timing. <P>SOLUTION: This lighting system is provided with an infrared ray transmitting part 2a, a transmitting part 4c and an infrared ray receiving part 2c. The infrared ray transmitting part 2a is a transmitting means having a period slot S3 and a slot S4 transmitting no signal, and the transmitting part 4c is a transmitting means for continuously transmitting a frame X. The time width of the sum of the slots S1 to S4 of the infrared ray transmitting part 2a is almost equal to or less than the time width of the sum of frames X1 to X5 of the transmitting part 4c continuously transmitting. The time width of the sum of the slot S3 and the slot S4 of the infrared ray transmitting part 2a is equal to or more than twice of the time width of the frame X of the transmitting part 4c. <P>COPYRIGHT: (C)2004,JPO</p> |
