H125CGDL-LP application field and working principle

Light Emitting Diodes, more commonly known as LEDs, are versatile light sources used for a wide range of applications in signboards, displays, and various indicators. The H125CGDL-LP is a type of LED designed for circuit board indicators and assemblies, and its application fields include status indication, panel and decorative lighting, backlighting, etc. Understanding how the H125CGDL-LP works and its features, can help users determine their selection of LED boards for various applications.

Features of H125CGDL-LP

The H125CGDL-LP uses a 3mm black lens and dome lens package design. It has built-in optics that allow illumination to be focused in a particular direction. In terms of electrical specs, the H125CGDL-LP operates at nominal 5V DC reverse voltage and is characterized by viewing angle of 110°. Furthermore, this type has brightness from 990mcd to 1050mcd and is RoHS compliant.

Working Principle of H125CGDL-LP

LEDs produce visible light by converting electric energy into photons of light. The electric energy is provided by electrons, which travel through the electric circuit and fill the PN junction of the LED\'s semiconductor. This electricity produces an electric field, causing the electrons to recombine and create light photons.

In the H125CGDL-LP LED, the anode pins provides the current and the cathode pins gives the return path. Applying power to the anode pin causes the built-in LED chip to light up, while applying power to the cathode pin causes it to turn off. Therefore, through controlling and alternating the current received by the anode and cathode pins, it is possible to adjust and program the light emissions of the LED.

Conclusion

The H125CGDL-LP LED is a type of LED designed to be used in circuit board design and assemblies, and can be used for various applications such as status indication and lighting. It has built-in optics that allow illumination to be focused on a particular direction, and can operate at a nominal 5V DC reverse voltage. Furthermore, it is capable of emitting a brightness level of 990mcd to 1050mcd. Understanding how this type of LED works and its features can help users select the ideal board for their intended application.
