There are two types of infrared receiver tubes, one is a photodiode and the other is a phototransistor. A photodiode converts light signals into electrical signals, and a phototransistor not only converts light signals into electrical signals, but also increases the discharge of electricity. Therefore, phototransistors……

Infrared remote controls have been widely used in color televisions, sound devices, and various electrical products. The control interval of the remote control can usually be between 6-8 meters, making it particularly convenient for application. Due to the extensive use of infrared remote control methods, their infrare……

Infrared: Before understanding infrared receiving LEDs, let's first understand what "infrared" is. Infrared is actually the abbreviation for infrared, which is a type of light in the spectrum (electromagnetic wave) that is invisible to the naked eye between 0.75 and 1000 microns. Infrared receiving LED is a d……

I believe everyone has encountered the situation of LED bead leakage in SMD, but the reasons for the leakage are different. Some SMD LED bead leakage is caused by testing after the LED bead packaging is completed, some is caused by long-term storage, some is caused by aging, and some is generated after welding. Today, ……

There are two main reasons why the SMD LED light does not light up: one is due to a problem with the light source, and the other is due to a problem with the power supply. At present, the light source of SMT LED lights is composed of LED light emitting diode beads. Firstly, disconnect the power supply at home, open the……

Many people tend to confuse infrared emission tubes with infrared receiver tubes, which may sound similar, but in practice, there are still significant differences in both appearance and internal structure. Firstly, in terms of appearance, the biggest difference between them is that the infrared receiver tube has three……

The latest sensing LED bead application 5g infrared thermal imaging temperature measurement is a lightweight deployment and multi scene sensitive application that integrates dual light monitoring, real-time temperature measurement, linkage control and storage with thermal imaging temperature measurement equipment. It p……

Characteristics of piranha lamp beads: high brightness, no central bright spot, average light concentration, low light attenuation, and multiple viewing angles. The cannibal fish lamp beads have a variety of luminous angles, which can be used as either astigmatic LED or spotlight LED, providing multiple angle options f……

Installation steps for the LED lamp beads of the piranha: First, select the piranha LED bracket, clean the bracket, fix the LED chip in the bracket bowl, confirm the size and depth of the bowl that is concave in the bracket, and then dry it. After drying, solder the two poles of the LED chip, and then select the corres……

1、 What is the use of laser LEDs? 1. Laser lamps, also known as laser lamps, have essential differences from spotlights. The original Chinese name of laser is l……

Distinguish between infrared emission tubes and receiving tubes from appearance: Infrared emission tubes: Generally, we can distinguish between infrared emission tubes and infrared receiving tubes from appearance. Infrared emission tubes are generally transparent and can clearly see the internal structure. The internal……

LED patch lamp beads and LED straw hat lamp beads are a category of products that are widely used in the current market. 1. From the appearance, the straw hat type LED lamp beads are straw hat type round (hence the name), with long pins; Most SMDLED lamp beads are rectangular shaped, with no pins or only very short pin……
