Abstract

The present application relates to an infrared emission angle adjustment structure, an infrared emission module using the infrared emission angle adjustment structure, and a remote control apparatus.The infrared emission module comprises a connecting member (10) and an emission angle adjustment member (20). The connecting member (10) is of a hollow cylindrical structure. The emission angle adjustment member (20) is arranged at one end of the connecting member (10) along an axis of the connecting member (10). The other end along the axis of the connecting member (10) is provided with a connecting portion (11) for connecting to an infrared light source. Infrared light emitted from the infrared light source passes through an inner cavity (12) of the connecting member (10) and is emitted to the outside after being adjusted by the emission angle adjustment member (20). According to the solution provided in the embodiments of the present invention, infrared light with a smaller divergence angle can be obtained, such that the infrared emission module using the infrared emission angle adjustment structure can emit basically collimated infrared light and can carry out directional remote control on a controlled device in a collimation control scenario, thereby avoiding a misoperation caused by an overlarge infrared light emission angle.

Description

technical field [0001] The embodiments of the present invention belong to the technical field of remote control, and in particular relate to an infrared emission angle adjustment structure, an infrared emission module and a remote control device using the infrared emission angle adjustment structure. Background technique [0002] In some remote-controlled devices, such as TV sets and air conditioners, infrared remote control is a commonly used remote control method. Communication to realize the function of remote control. [0003] The infrared light source used in the existing infrared emission modules is generally an infrared LED, and the divergence half angle of the infrared LED currently on the market can only reach a minimum of 15°, such as figure 1 As shown, when remote control is carried out at a long distance, the infrared rays emitted by the infrared transmitter module can cover a large range. Often, when the infrared transmitter module (infrared LED) of the remote ...
