通常情况下,同遥控型家用电器配套使用的红外遥控发射器(以下简称遥控器)的正常控制作用距离一般为6~8 m,遥控角度即以遥控器红外光辐射点为顶点的圆锥角在30°以内。遥控器在使用中若感觉到控制灵敏度不如往常,遥控距离和遥控角度明显减小,而且在更新电池后,其作用效果并无显著改善时,就非常有必要考虑红外光遥控信号传播途径方面的问题。
Under normal circumstances, with the remote control supporting the use of household appliances infrared remote control transmitter (hereinafter referred to as the remote control) normal control distance is generally 6 ~ 8 m, remote control angle that is the remote control infrared radiation point for the vertex cone angle Within 30 °. Remote control in use if you feel less than normal control sensitivity, remote control distance and remote control significantly reduced, and after the battery is updated, the effect did not significantly improve, it is necessary to consider the infrared remote control signal transmission path problem.
