Infrared emission angle adjustment structure, infrared emission module and remote control device

Abstract

The application relates to an infrared emission angle adjustment structure and an infrared emission module and a remote control device adopting the infrared emission angle adjustment structure, wherein the infrared emission module includes a connecting piece (10) and an emission angle adjusting piece (20); the connecting piece (10) It is a hollow cylindrical structure, and the emission angle adjusting part (20) is arranged at one end of the connecting part (10) along the axis of the connecting part (10); the other end of the connecting part (10) along the axis is provided with a connection for connecting an infrared light source part (11), the infrared light emitted by the infrared light source passes through the inner cavity (12) of the connecting piece (10), and is regulated by the emission angle adjusting piece (20) before being emitted to the outside. According to the solution provided by the embodiment of the present invention, infrared light with a small divergence angle can be obtained, so that the infrared emission module adopting the infrared emission angle adjustment structure can emit substantially collimated infrared light, and the controlled infrared light can be controlled in the collimation control scene. The device performs directional remote control to avoid misoperation due to excessive 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 ...
