LEDs are often used as indicators in a plethora of applications. They have the unique ability to display rapid changes, respond to signals from a distance, and can be seen in a variety of lighting conditions. Discrete LEDs are employed in a variety of situations providing an array of signaling, warning and status information - from simple logic signals to sophisticated safety warning systems. Utilizing different power sources, discrete LEDs are constructed into various shapes and sizes to meet the needs of the application.The LTL-2R3VRKNT from Kingbright is a rectangular shaped 547-550nm Super Bright yellow discrete LED. The device provides 15mcd at 20mA. The discreteness of the device is an advantage when it is used in applications that require a focused and intense light projection over a long distance. The package purpose of the LTL-2R3VRKNT is 3 mm long by 2 mm wide, making it suitable for applications that require a small size. This device is an excellent choice for applications that require high intensity, directional light sources.

The LTL-2R3VRKNT’s application field consists largely of signal indication and harsh environment uses. The output of the device is focused, making it suitable for use as a warning device that can be seen in a variety of lighting conditions. It is suitable for use in outdoor warning devices such as streetlight indicators, and can be used in a variety of indoor applications requiring intense and concentrated light projection. The device is also suitable for use in light responsive applications such as light sensing/detection systems and as an input device for some light sensitive industrial applications.

The working principle of the LTL-2R3VRKNT is simple. It consists of an LED die that is encapsulated within an insulating epoxy which provides protection for the LED die and works as the LED’s package. As a result, the LED is created to provide specific levels of output power, light spectrum and direction. The device is powered by joule heating, a process where a current flow is established within the LED die and heat is produced. This is then converted into light energy and outputted from the LTL-2R3VRKNT. The power input determines the intensity and type of light output. When powered, the device produces a narrow, intense beam of light ouput.

Due to its long-range focused output, small size and the capability to withstand water and shock, the LTL-2R3VRKNT is the ideal device for many of the harsh environment and signaling applications. It has the capability to provide a consistent and intense light output. Its narrow focused beam helps to provide rapid response to signals from a distance and makes the device the perfect choice for warning, sensing and signaling applications.
