The invention discloses an infrared receiving plate with a signal transmission window. The infrared receiving plate comprises the signal transmission window, a baseplate and a fixing plate, an infrared receiving module and an LED light emitting module are welded on the baseplate, the fixing plate is connected on one side of the baseplate, a power source filter module, an input-output connecting device, a socket connecting device and an LED current limiting circuit are mounted on the fixing plate, and the signal transmission window is formed by directly pouring the baseplate after the infrared receiving module and the LED light emitting module are welded on the baseplate. The signal transmission window is directly poured on the surface of a chip by adopting an integral pouring mode, so that size of the remote-control infrared receiving plate is reduced greatly; the infrared receiving plate is suitable for narrow-side display or electronic remote control equipment.
Description
technical field [0001] The invention relates to the technical field of remote control receiving boards, in particular to an infrared receiving board with a signal transmission window applicable to narrow-edge equipment. Background technique [0002] In order to realize the remote control of equipment such as TV, DVD, VTR, air conditioner, etc., an infrared remote control signal receiving unit (that is, an infrared remote control receiving board) needs to be installed on the casing of these devices to receive signals from the infrared remote controller (infrared remote control) ) and other remote control signals sent by the remote control signal sending unit. In order to effectively receive the remote control signal sent by the infrared remote control, usually the front of the infrared receiving head of TV, DVD, VTR, air conditioner and other equipment is equipped with a remote control receiving window and a device working status indication window. The function of this window...
