LED Indication - Discrete

LEDs (Light Emitting Diodes) are becoming increasingly popular as a source of lighting due to their compact size, low cost, and wide range of applications. The engineering of LED technology has made large leaps forward, allowing for the production of powerful and efficient small form factor lights that are ideal for a number of lighting applications. A range of LED products are available, one of the most popular being the QTLP650CRTR. This article looks at the application field and working principle of the QTLP650CRTR.

The QTLP650CRTR is a discrete size surface-mount LED indicator, designed primarily for providing visual indication of on/off or lighting conditions. This particular product is suitable for use in a wide range of applications, such as controlling room atmosphere, functioning as a warning light, or providing general illumination. Its design is very simple yet effective, featuring a bright white Dome emitter that has long service life and excellent thermal characteristics.

The effective output of this device is 15 Lumens, which is more than enough for most applications. This device has a forward voltage (Vf) of 3.2 V and a reverse voltage (Vr) of 6.5 V. Additionally, its forward current (If) is equal to 700 mA, allowing for excellent thermal performance. In terms of overall operation, the operating temperature range of the device is between -40° C and +85° C, with a max junction temperature of +125° C.

In terms of its working principle, the QTLP650CRTR essentially functions by converting electrical energy into light. This is done through the use of a vacuum-sealed electroluminescent diode. This diode is made up of a P-type semiconductor and an N-type semiconductor, which affect the current and thus the light emitted. The forward bias causes the electrons to flow from the N-type to P-type semiconductor, giving it its distinctive electrical characteristics.

When the current is sufficient, it produces an electron-hole pair and this will emit a photon. This continuous transfer of electrons produces light, which can then be closely controlled using the voltage and current. This makes the QTLP650CRTR ideal for applications that require very precise light output, as well as applications that require low amounts of power.

In conclusion, the QTLP650CRTR is a versatile surface-mount LED indicator, suitable for a wide range of lighting applications. It is relatively easy to install, with its simple operating principles making operation effortless. This device has excellent thermal characteristics thanks to its forward voltage (Vf) and current (If) which allows for efficient and adjustable illumination. Overall, the QTLP650CRTR is a great choice for providing visual indication of switching or lighting conditions.
