IntroductionLED indication is divided into discrete indication and continuous indication. PY1105CK-TR is a type of discrete indication LED, which can provide a wide range of application options with advantages such as high reliability and low cost. This article will explain the application field and working principle of PY1105CK-TR.Application FieldPY1105CK-TR can be used in various application areas and scenarios, including home appliances, computer accessories, audio and video products, power supplies, and communication methods to provide simple and reliable indicator status display.For home appliance manufacturers, PY1105CK-TR can be used for power on/off status, alarm status, enter status, etc. Its earthquake-proof structure makes it more reliable despite the high-intensity vibration generated by household appliances.For computer accessories, PY1105CK-TR is ideal for indicating the power on/off status and system temperature. Its wide viewing angle and superior visibility make it suitable for desktop cases, motherboard power LED indicators and other PC-related applications.As for audio and video products, PY1105CK-TR is mainly used for the power on/off status display of audio and video products such as MP3 players, video cameras and speakers.For power supply applications, PY1105CK-TR is mainly used for indicating the power on/off status of UPS/EV systems, generally located near the UPS power switch and also with self-test functions.Communication methods also need to use PY1105CK-TR. It is mainly used for the power on/off status display of communication devices, e.g. audio/video routers, data switches and digital modems.This is a brief introduction to the application field of PY1105CK-TR, when each in practical application, still need to make corresponding choice according to different practical condition.Working PrincipleThe working principle of PY1105CK-TR is based on the basic principle of optics. Light is generated when electricity flows through the output side of a PN junction diode. The shorter wavelength of the diode\'s light output is absorbed by the opaque layer, while the longer wavelength of the diode\'s light output is emitted in all directions and acts as a light-emitting indicator.When the PY1105CK-TR is in operation, the voltage applied to the anode will cause the electrons to go to the PN junction, forming a current path. The current passing through the diode will generate light of a certain wavelength. This wavelength of light is filtered by the black coating on the inside of the PY1105CK-TR, while the longer wavelength of the diode\'s light output emits in all directions and acts as a light indicator.ConclusionThe PY1105CK-TR is a type of discrete indicator LED with advantages such as high reliability and low cost. This article explains its application fields and working principles, enabling readers to better understand the product\'s advantages. PY1105CK-TR has a wide range of applications and can be used in home appliance, computer accessory, audio and video product, power supply and communication field. It utilizes the basic principle of optics and uses the longer wavelength of the diode’s light output as a light-emitting indicator. With the rapid development of modern industrial technology, the demand for discrete and continuous indicator displays is increasing rapidly. PY1105CK-TR discrete indicator LED provides a wide range of application options and its reliable performance is of great significance for electronic product design.
