INFRARED LED ARRAYING METHOD OF LIGHT EMISSION UNIT FOR INFRARED COMMUNICATION |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide an infrared LED arraying method of a light emission unit for infrared communication whose infrared communication range is hardly influenced by environmental light by limiting the infrared communication range when a plurality of infrared LEDs are used. <P>SOLUTION: The infrared LEDs 3 are horizontally arranged according to the outside of a infrared irradiation range to make definite the limited infrared irradiation border P of the infrared communication range of the infrared LEDs 3. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
