最近几年,用于控制电视机、录像机、线缆解码器等设备的各种功能的红外遥控发射器已经变得相当广泛了。结果是,一个用户往往要面临许多个不同的遥控器,以便用它们来控制由不同厂商生产的各种不同设备。为了最大限度地减少用户所需的遥控器的数量,就需要有具有学习功能的通用遥控发射器。本发明提供一种可以与学习型遥控器一起使用的改进型红外二极管电路。在一个具体装置中,该电路用同一个红外发光二极管发射和接收红外信号,它可以作为遥控器的红外输出电路的一个元部件;在另一个具体装置中,该电路给一个红外发光二极管和一个红外光电
In recent years, infrared remote transmitters for controlling various functions of devices such as televisions, video recorders, cable decoders and the like have become quite extensive. The result is that one user often faces many different remote controls in order to use them to control a wide range of different devices manufactured by different vendors. In order to minimize the number of remote controls the user desires, a universal remote control transmitter with learning capabilities is required. The present invention provides an improved infrared diode circuit that can be used with a learning remote control. In a particular arrangement, the circuit emits and receives infrared signals from the same infrared light-emitting diode, which may be used as a component of the remote control infrared output circuit. In another embodiment, the circuit provides an infrared light-emitting diode and a Infrared photoelectric
