bedrijfsnieuws over LED Application Scenarios: 2X5X7mm Green Through Hole LED for Indicator Lights and Display Panels

LED application scenarios are everywhere around us — from the tiny power indicator on your charger to large outdoor display panels. In the world of led through hole components, the classic square-lamp package remains one of the most trusted choices for designers. In this article, we highlight one specific model from the catalog of Dongguan Lanjin Optoelectronics Co., Ltd.: the 2X5X7mm square green light LED (dominant wavelength 520–535 nm), and walk through its most valuable application scenarios.

1. Why Choose a 2X5X7mm Through Hole Green LED?

The 2X5X7mm rectangular package offers a bright, uniform emitting area that is easy to mount on PCB and compatible with wave soldering. Driven at only 20 mA with a forward voltage of 2.8–3.4 V, this led through hole diode delivers a typical luminous intensity of 2,500 mcd at 520–535 nm — a pure green light that the human eye perceives with maximum sensitivity, making it ideal for status indication and signage.

2. Featured Model: Lanjin 2X5X7mm Green LED Diode

Produced by Dongguan Lanjin Optoelectronics Co., Ltd. (est. 2005, ISO9001:2015), this green light LED uses well-known San'an/Epistar chips, 99.99% gold wire bonding and high-reliability epoxy encapsulation. Its long lifespan of 50,000–60,000 hours and low DC operation make it more energy efficient than incandescent and most halogen lamps.

3. Typical Application Scenarios of Green Through Hole LEDs

• Indicator & Status Lights: Power-on indicators, charging status lamps and fault alerts in power supplies, chargers, appliances and industrial control panels.
• Display & Signage: Dot-matrix message boards, elevator floor indicators, exit signs and channel letters where the green light LED delivers crisp visibility day and night.
• Automotive & Traffic Lamps: Dashboard tell-tales, brake light monitors and traffic signal modules requiring long-life, high-reliability led through hole components.
• Backlight & Decorative Lighting: LCD backlights, craft flashlights, reading lamps and decorative fixtures benefiting from uniform green emission.
• LED Modules & Strips: Easy PCB assembly for signage modules and flexible strip lighting in indoor and outdoor environments.

4. Why Buy from Dongguan Lanjin Optoelectronics?
