Street lighting installation reference<\/h2>\n\n\n\n

The supplied installation photograph shows workers using an elevated work platform beside a road luminaire. A blue control device is visible on top of the luminaire. The photograph illustrates a mounting arrangement; the specific controller model, project location, installed quantity and commissioning date have not been independently confirmed.<\/p>\n\n\n\n

Illustrative energy calculation: LED dimming<\/h2>\n\n\n\n

The following calculation is a separate illustrative scenario based on assumptions presented in the 2019 UMELINK solution brochure, pages 14\u201315. It is not a measured result from the photographed installation.<\/p>\n\n\n\n

Assumptions: 10,000 luminaires, 11 operating hours per day, 365 days per year and an illustrative electricity price of RMB 0.86\/kWh. The dimmed case assumes a 70 W average input over those operating hours.<\/p>\n\n\n\n

Annual result<\/th>100 W LED baseline<\/th>Assumed 70 W average with dimming<\/th><\/tr><\/thead>
Electricity consumption<\/td>4,015,000 kWh<\/td>2,810,500 kWh<\/td><\/tr>
Electricity cost<\/td>RMB 3,452,900<\/td>RMB 2,417,030<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The calculated annual reduction is 1,204,500 kWh (30%) and RMB 1,035,870. Annual consumption = quantity \u00d7 average input watts \u00f7 1,000 \u00d7 operating hours. Annual electricity cost = annual consumption \u00d7 electricity price.<\/p>\n\n\n\n

These figures are recalculated from the stated assumptions rather than copied from the brochure\u2019s inconsistent totals. The brochure\u2019s combined 75% claim includes a lamp-replacement comparison and must not be attributed to a receptacle or controller alone.<\/p>\n\n\n\n

Applying the example to a project<\/h2>\n\n\n\n

Actual savings depend on the load, driver dimming response, operating schedule, required illumination, metering boundary and control-system consumption. Confirm electrical compatibility, wiring, orientation and sealing against the applicable installation instructions. Compare measured consumption under equivalent lighting-service conditions before claiming project savings. A receptacle alone does not provide the dimming strategy.<\/p>\n\n\n\n
