KDC Q21 Series LED Street Light: Innovative Detachable Power Supply Design

The KDC Q21 Series LED street light features an external plug-in power supply, combining exceptional design philosophy with an innovative detachable structure. It brings a transformative upgrade to outdoor lighting applications. This series is tailored for various outdoor lighting scenarios, including street lights, shoebox lights, courtyard lights, and high mast lighting. Power ranges include 35W, 50W, 75W, 100W, 150W, 240W, and 300W.

At this year’s Guangzhou International Lighting Exhibition, the Q21 Series attracted significant attention from visitors and potential partners thanks to its unique external plug-in power supply design.

As outdoor lighting evolves toward greater efficiency, convenience, and intelligence, the Q21 Series stands out with the following key features.

NFC Wireless Programming Technology

The power supply supports NFC (Near Field Communication) programming, enabling fast and efficient parameter adjustment without wiring or powering on. A simple tap is all it takes, significantly improving installation and maintenance efficiency.

Integrated Smart Photocell Control

Equipped with a built-in multi-point light-sensing circuit, it accurately distinguishes natural and artificial light, eliminating the need for external photocell modules. This simplifies system design while enhancing stability and reliability.

Detachable External Power Supply

The plug-in rotary design allows for quick installation, removal, and replacement of the power supply. It improves maintenance efficiency, reduces labor costs, and allows the power supply to be shipped as a separate accessory, lowering import costs for distributors.

High Efficiency & Long Lifespan

With an efficiency rate of up to 94.5%, the power supply helps reduce energy consumption. Timer-based dimming and switch control support energy-saving strategies tailored to regional or seasonal needs. The external power design enhances airflow for better heat dissipation, prolonging the lifespan of the luminaire.

Compact Design for Cost-Effective Logistics

The external power supply reduces the size of the luminaire’s internal cavity, minimizing overall product dimensions. This optimization lowers packaging volume, storage costs, and transportation expenses.

Reliable Performance with Rigorous Testing

The power supply passes 5G vibration testing, ensuring it remains secure after installation. It also meets IP66/IP67 waterproof standards and undergoes 1000-hour salt spray, UV resistance, and IK08 impact tests—guaranteeing performance in harsh environments. A 5-year warranty is provided for added assurance.
