LEDs have been widely used in various applications including Indication - Discrete. QTLP9138GR is one kind of LED specifically used in this application field and with its own unique working principle. In this article, we will discuss the application field and working principle of this LED in detail.

The QTLP9138GR LED by Teledyne Optoelectronics is specifically engineered for the Indication - Discrete application field. It has two built-in color LEDs, and one white LED, all in a ceramic package. It features a narrow-angle radiation for good distinction, and low power consumption, suitable for applications where long battery life is needed. It also features excellent moisture resistance for long-lasting operation in a wide range of environments. The QTLP9138GR LED is a great option for battery operated applications such as medical devices, barcode scanners, portable meters, access control systems, and more.

So how does the QTLP9138GR LED works? It operates with a constant-current DC drive supply, which maintains LED brightness regardless of the varying voltage supply. The LED emits light when the current passing through it increases beyond the breakdown voltage. The LED illuminates when the short-circuit current passes through it and turns off after it reaches a certain current level. The higher the current, the brighter the LED emits. The brightness and color of the LED can be adjusted by controlling the pulse width and duty cycle of the input and current supply. The QTLP9138GR LED allows users to modify both the brightness and color of the LED, making it the ideal choice for applications that require a dynamic display.

The QTLP9138GR LED also has a number of safety features. It features a reverse polarity protection to protect the LED from a potential reverse voltage, and a temperature protection circuit to ensure that the LED does not overheat. The LED is also ESD protected from electrostatic discharge, making it reliable for long-term applications. These safety features make the QTLP9138GR LED a safe and reliable choice for many applications.

The QTLP9138GR LED is a versatile and reliable choice for applications in the Indication-Discrete field. Its constant-current DC drive and ESD protection make it an ideal option for battery operated applications. Its narrow angle radiation and adjustable brightness and color make the LED an ideal choice for dynamic displays. Its safety features also make it a great option for more demanding applications. With its wide range of features, the QTLP9138GR LED is sure to fulfill the needs of many applications in the Indication-Discrete field.
