Infrared LED (Light Emitting Diode) beads are a type of optoelectronic component commonly used in devices such as infrared sensors and remote controls. To ensure the normal operation of infrared LED chips, we need to use some methods to test their quality. Next, we will understand a commonly used method for measuring t……

Infrared emission tubes (IRLEDs), also known as infrared emission diodes, belong to the category of diodes. It is a kind of light-emitting device that can directly convert electric energy into near-infrared light (invisible light) and emit it. Mainly used for various photoelectric switches, touch screens, and remote co……

Infrared remote controls have been widely used in television, sound, and various household appliances. A remote control can be used to remotely control electrical appliances within 6-8 meters of an ordinary station, making it very convenient to use. Due to the large usage of infrared remote control methods, their infra……

Which one is more suitable, direct insertion LED beads or surface mount LED beads? How to choose, many people are not clear. Today, the editor will discuss this issue with you. Direct plug-in LED beads are a common electronic component that have pins that can be stopped by inserting them into sockets on circuit boards.……

Infrared LED beads are electronic components that emit infrared light. They are based on semiconductor materials and emit light by injecting current. Unlike ordinary LED chips that emit visible light, infrared LED chips mainly emit infrared light. The principle of infrared LED beads is to inject current into the semico……

5mm diameter plug-in LED beads are a common LED lighting component with multiple parameters and characteristics, which are crucial for selecting suitable beads ……

The semiconductor materials used in infrared emission and reception tubes are usually gallium arsenide (GaAs), gallium aluminum arsenide (GaAlAs), etc., packaged in fully transparent or light blue, black resin. At present, the application of infrared emission and reception tubes is mainly as signal sources for various ……

With the development of technology, the application range of infrared LED chips is becoming increasingly common, such as CCB cameras, surveillance systems, infrared cameras, machine vision systems, and so on. Infrared light, due to its commonality, cannot be perceived by the human eye, but sensitive semiconductor data ……

With the continuous development of technology, the application of infrared LED beads in various fields is becoming increasingly common. As a special type of LED bead, infrared LED beads emit light that is invisible to the human eye, bringing many conveniences to our lives. This article will introduce the principles, ap……

The fundamental structure of infrared LED beads is a piece of electroluminescent semiconductor material, placed on a lead frame, and then sealed with epoxy resin around, praying for the maintenance of the internal core wire, so the seismic performance of infrared LED beads is good. Characteristics of infrared LED bead ……

The LED product of piranha lamp beads requires a light source to be lit, and the lighting time is relatively long. If the quality is not up to standard, it will not only fail to meet the needs of residents, but the later management and maintenance of piranha lamp beads is also a significant task. If the price is too ex……

The plug-in LED beads are mainly composed of five materials: bracket, silver glue, chip, gold wire, and epoxy resin. 1、 Plug in LED bead bracket 1. Function of bracket: conductivity and support 2. Composition of bracket: The bracket is formed by electroplating the bracket material, consisting of five layers from the in……
