Characteristics of LED piranha: The LED piranha has four legs, two more than a typical 5mm LED, and the light emitting portion of the four legs is at a certain distance from the welding point of the circuit board. The space reserved for the design of the four legs is to allow the LED piranha to dissipate much better he……

Inline light emitting diodes, also known as plug-in light emitting diodes, are energy-saving and environmentally friendly visible lighting materials. They are solid-state semiconductor devices that can convert electrical energy into visible light. The light-emitting principle of LEDs is to make electric current flow th……

LED piranha is also a kind of lamp bead that we often encounter. It is a square transparent resin encapsulated LED with four pins. With the development of LED, the application of LED piranha has become increasingly widespread. For example, we can use LED piranha to make car brake lights, steering lights, reversing ligh……

(1) Long working life: As a conductive solid-state light emitting device, LEDs have a longer working life than other light emitting bodies. Its brightness half-……

Choosing the quality of LED lamps is a very important factor. Different packaging processes can have a significant impact on product quality. Compared to LED lamps packaged with Class A low attenuation adhesive, LED lamps packaged with ordinary primer have a 76% reduction in light attenuation under the same aging envir……

People habitually refer to infrared emission tubes and infrared reception tubes as infrared pairs. The appearance of an infrared pair tube is similar to that of an ordinary circular light-emitting diode. For those who first come into contact with infrared detectors, it is difficult to distinguish between the transmitti……

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……
