KINGBRIGHT L-937GYW Bi-Colour Green/Yellow LED, 3mm

The KINGBRIGHT L-937GYW is a versatile 3mm bi-colour indicator lamp designed for clear status signalling in a variety of electronic applications. Featuring a white diffused lens, this LED provides uniform light output and excellent visibility from a wide 60-degree viewing angle. Its solid-state construction guarantees long operational life and exceptional reliability under demanding conditions.

This component houses two distinct light-emitting diodes in a single through-hole package. The green light is produced by a gallium phosphide (GaP) diode, while the yellow light is generated by a gallium arsenide phosphide on gallium phosphide (GaAsP on GaP) diode. This efficient design allows for low power consumption and dependable performance across an extensive operating temperature range from -40°C to +85°C.

Key Features & Specifications

• Bi-Colour Output: Emits distinct green and yellow light for dual-status indication.
• Efficient Design: Low forward current requirements (Green: 25mA, Yellow: 30mA) contribute to energy efficiency.
• High Visibility: White diffused lens ensures a soft, evenly distributed light. The green LED offers a luminous intensity of 20mcd, and the yellow provides 8mcd.
• Robust Construction: Solid-state technology ensures a long lifespan and resistance to shock and vibration.
• Wide Operating Range: Suitable for use in environments from -40°C to +85°C.
• Clear Electrical Parameters: Forward voltage is 2.2V for green and 2.1V for yellow, with peak wavelengths of 568nm (green) and 588nm (yellow).

With its compact 3mm diameter and standard through-hole mounting, the L-937GYW is easy to integrate into printed circuit boards (PCBs) for prototypes, industrial control panels, consumer electronics, and diagnostic equipment where reliable, dual-colour indication is essential.
