Introduction

LED Indication - Discrete is a type of illumination used in many applications such as lighting, hints, text and symbols for product identification and interface. The basic structure of this kind of discrete indicators typically consists of a light source, a lens or reflector, and a housing. The TLHP4400 is an example of this discrete indicator, and it is commonly used in various applications. This article will discuss the TLHP4400 application field and its working principle.

TLHP4400 Application Field

TLHP4400 is a discrete indicator that can be used in many applications. It is usually applied in industrial, automotive, commercial and residential application. Industrial application is the most popular use for the TLHP4400. It is used as a mean of warning, notification and safety in industrial production, such as metalworking, material pressing, welding, drilling and so on. The discrete indicator ensures timely warning and reminder to make the industrial production environment safer and more efficient. In car manufacturing, TLHP4400 discrete indicator is used mainly as a warning system. It is installed in many locations inside the car, such as engine compartment and dashboard, to provide prompt feedback and reminder to the users. This ensures the safe and comfortable experience of the driver and passengers. In commercial and residential applications, TLHP4400 is adopted as an attractive indicator. It is used mainly as a mean to notify the presence of a certain product or services. It is generally installed in the storefront, showcase and hall entrance. The functional and visually appealing discrete indicator also gives security and after-sales customer service.

TLHP4400 Working Principle

TLHP4400 discrete indicator mainly consists of three parts, the light source, the lens or reflector and the housing. The light source is a LED light contained in a tiny chip, typically a LED red light. The LED output power is determined by the current that is passing through it, usually 10 to 20 milliamps. The current passes through the LED light, and the voltage changes accordingly. Then, the light source emits bright light in the direction of the lens or reflector. The lens is used to concentrate the light, while the reflector is used to reflect the light. The energy of the light changes the voltage to the polarity of the LED light, which maximizes the voltage sent to the resistor, thus allowing the light source to last longer. The housing is made of ABS or PC, which protects the light source and prevents the light source from being easily damaged. The housing also serves as an adjustable window, allowing the light to exit out at an angle specific to the needs of the application. The housing also ensures the brightness and visibility of the light, and safeguards the users from being exposed to the intense light of the LED light.

Conclusion

The TLHP4400 is a widely used discrete indicator. It offers a wide range of applications, including industrial, automotive, commercial and residential applications, and is an efficient warning system and attractive indicator. Its working principle consists of the LED light, lens or reflector, and housing. Together, these components provide the desired effect in the various application areas. In conclusion, TLHP4400 is an efficient and functional discrete indicator, suitable for many different applications. Its sophisticated design and working principle make it a versatile and reliable indicator for a wide range of applications.
