Case Study: Energy Efficient LED Streetlights Suit Huizhou

Category: Illumination

Huizhou city is located in southern China, in the central Guangdong province and close to Hong Kong. This is home to the latest retrofit of 150-400W high pressure sodium (HPS) streetlights to energy-efficient luminaires. The goal of the project was to upgrade 20,000 existing streetlights in a 1:1 fashion to Huizhou ForYou Optoelectronics luminaires with LUXEON T LEDs.

High luminaire reliability, high energy efficiency and low net system cost were the key requirements for this project. In addition, because the roadways feature HPS lamps with varying pole heights (5–14m), different luminaire and secondary optical designs were needed to meet the various light distribution requirements.
