Description

Technical Field

[0001] The utility model relates to the technical field of infrared pairs of tubes, and specifically relates to an anti-interference infrared transmitting and receiving pair of tubes. Background Technique

[0002] An infrared light-emitting diode is a diode that can emit infrared rays, and is usually applied to occasions such as remote controls and photoelectric automatic control. There are two ways of infrared emission and reception. One is the direct emission type, and the other is the reflection type. The direct emission type means that the light-emitting tube and the receiving tube are relatively arranged at both ends of the emitter and the controlled object, with a certain distance in the middle; the reflection type means that the light-emitting tube and the receiving tube are arranged side by side. Usually, the receiving tube has no light illumination, and only when the infrared light emitted by the light-emitting tube encounters a reflector, the receiving tube receives the reflected infrared light and generates a photoelectric signal.

[0003] However, the infrared transmitting tube and the infrared receiving tube of the above prior art are generally exposed outside, and are easily contaminated with dust, which will then cause certain interference to the infrared rays emitted by the infrared transmitting tube and the infrared rays received by the infrared receiving tube, affecting the transmission of infrared rays. Content of the Utility Model
