LED Indication - Discrete

SLI-343UR3FW, otherwise known as a Discrete LED Indication Light-Emitting-Diode (LED) device, is a visual signaling device that is used to convey information, especially in aircraft and other high-stakes applications. As compared to incandescent bulbs, LED lighting provides more durability and efficiency, yet still produces a high amount of brightness. It can be easily configured, integrated and installed in a variety of setups.

Application Field

SLI-343UR3FW\'s typical application field includes military, aerospace, aviation and marine vehicles. In aircraft, it is typically used to provide information to the pilots by replacing traditional devices such as warning lights, buzzers and control panels. SLI-343UR3FW is also used in communications systems, with the added benefit of being more efficient compared to alternative technologies, like silica-based devices.

SLI-343UR3FW is also used in the medical industry, and in transportation, especially with revolving signs as a traffic indicator such as in a school zone or traffic intersection. It is also ideal for lighting up signaling buttons, switches and displays in the automotive sector.

Working Principle

SLI-343UR3FW is a diode-based LED indicator. It comprises of a semiconductor diode (SLI-343UR3FW) and a phosphor material, which is predetermined for efficient optical performance and tailored for the application. The LED emits light whenever a current is supplied to the diode. Depending on the manufacturer, the diode may be bipolar or three-level (uni-polar or bi-polar). The light emitted by the diode can be in the form of continuous or discrete light. Generally, the brightness and luminosity of the LED is proportional to the current.

SLI-343UR3FW is composed of a single LED circuit, along with a light guidance system that directs the LED light. The light guidance system consists of a specialized optical grade reflector, a set of lenses, infrared filter, radiation diodes and a black border around the diodes. The circuitry of the device contains a current regulating function to maintain a constant brightness of the LED, and a circuitry protection to protect the device from overheating and potential damage.

The radiation diodes also allow SLI-343UR3FW to be used in applications such as sensing or servo control systems. The radiation diodes adjust the intensity of the emitted light to ensure a smooth viewing experience. During daylight, the emitted light from the device is controlled by the radiation diodes, and during night, the emitted light from the device is adjusted to appropriate levels depending on the application.

SLI-343UR3FW is easy to maintain and has a long lifespan. It requires minimal power to operate and is usually activated by a low-voltage power supply. It is normally connected to the No. 406 panel assembly, an arrangement of light-emitting diodes and other components that are used for its operation. All these components work together to produce the accurate light levels required for effective operation.
