Twist Lock Photocell

Longjion Intelligence has launched the JL-2 and JL-7 series of photocontrollers. The JL-2 series, based on the NEMA interface, encompasses rotary lock thermal, multi-voltage analog electronic, digital electronic, and smart cloud-connected types, all complying with ANSI standards. The products feature a cylindrical design with a transparent light-sensing window and rotary lock brass plugs, and some models are equipped with gold-plated contacts. The JL-7 series, on the other hand, adheres to Zhaga standards, offering automatic brightness adjustment, remote monitoring support, and multiple control modes including light sensing and microwave sensing. It is suitable for indoor and outdoor lighting as well as luminaire integration, simplifying the installation process. Both series boast multiple sensing methods, strong adaptability, flexible installation, high compatibility, and energy-saving features, enabling on-demand lighting control.

Haiyan Project

1. Geographic Position

Haiyan County is located in the northwest of Hangzhou Bay, belonging to Jiaxing City in Zhejiang Province, 118 km from Shanghai and 98 km from Hangzhou. It has 9 towns (subdistricts). It has a land area of 534.73 square kilometers and a population of 430,900

2. Project Context

Street lamp management has been managed by the State grid into direct government management
It has been listed as a key project of Haiyan County's "13th Five-Year Plan"
Local enterprises are determined to carry out construction for the project
It will be carried out in stages, from the town (street) to the urban area
The 106 street lights (including 6 security monitoring street lights) in the first phase of the project have been completed. The government invested 350,000 yuan in the first phase of the project, including lamps, control equipment and street light control system, excluding construction and installation
