When purchasing a controller, have you noticed whether the controller you bought is an IR model or an RF model? Do you know how the IR controller controls the light strips and what its working principle is? In the light strip controller, IR is the abbreviation of Infrared Radiation, meaning infrared rays. It is a wireless communication technology that uses infrared light waves to transmit signals and is widely applied in scenarios such as remote control of household appliances and control of lamps. This article will provide a detailed introduction to the working principle, advantages and disadvantages, as well as the frequently used scenarios of IR.

LED Strip Lights (light strips) have a wide range of applications. The following is a detailed overview of its main application scenarios:

Many customers purchase low-voltage running light strips but do not know how to connect and operate. This article will explain in detail the connection steps, operation methods and precautions of low-pressure running light strips, so as to help customers easily get started and create ideal lighting effects.

The controller of RF technology controls the light strips led through wireless radio frequency signals, featuring no need for alignment and a relatively long control distance. It is widely used in various scenarios such as homes, commercial Settings, and stages. It can control various types of lights, such as RGB, CCT, RGBCCT, single color, high-voltage COB, and addressable led strip, etc. It can not only adjust the color temperature, brightness and speed, but also provide more abundant and flexible lighting control options. This type of strip light usually has high flexibility and controllability, etc. This article will provide a detailed introduction to various types of strip lighting that RF technology can control, as well as their characteristics and application scenarios.

In the light strip controller, IR (infrared) and RF (radio frequency) are two common wireless communication methods. The IR controller uses infrared rays, with wavelengths typically ranging from 1um to 100um and frequencies between 300GHz and 400THz. It usually requires a direct line of sight between the transmitter and receiver, meaning there should be no obstructions between them. For instance, like a TV remote control, it needs to be aimed directly at the device to operate. RF uses radio waves, with frequencies typically ranging from 3kHz to 300GHz. It does not require a line of sight and signals can penetrate walls, furniture, and other objects. Therefore, the distance and position restrictions between the controller and the light strip are relatively small. This article will detail other differences between IR and RF in their applications.
