DMX-controlled LED wall-washing, floodlights, and roofline lighting bring energy-saving night illumination to Tiejiangjun's factory park in Zhongshan, China.
At the Tiejiangjun factory park in Dongfeng, Zhongshan, Guangdong, this project designed a night-time architectural lighting scheme covering the main building, the expert building, the dormitory block, and the entrance canopy, modeled in DIALux against the site's white 100×100mm ceramic-tile façade (maintenance factor 0.8, 18% reflectance).
The scheme specifies LW-24WW 24W LED wall washers (DC24V, DMX-controllable, 3000–4000K warm white) mounted about 2m above grade and 0.5m off the wall, spaced 1.5m apart and angled 5° inward toward the sky; LN 903300 50W LED flood lights (AC220V, 3000–4000K warm white) at the four main structural columns, five fixtures per column; and LW-10005050-D4816 8W LED tube fixtures (DC12V, DMX-controllable) mounted flush along the roofline, aimed 90° outward across the parapet face.
Lighting is run on a DMX512 control network with two programmed states — full-rated output and a reduced, half-brightness mode after midnight for energy saving — switched automatically by a GPS-referenced sunset/sunrise signal.
Rather than reinstall the original metal-letter Tiejiangjun sign, at risk of damage, deformation, and imprecise hole spacing if removed, the design calls for a new sign fabricated from 2.0mm laser-cut aluminum panel, about 2m × 2m × 0.2m, outlining the characters with 9mm-diameter white LED point-light strings (12mm mounting holes, DC5V) set at a 25mm hole pitch and powered from a rooftop supply for weatherproofing and ease of maintenance.
Together, the wall-washed façades, column floodlighting, roofline outlining, and illuminated signage give the factory park a coordinated night identity, while the DMX/GPS dimming schedule keeps running costs down after midnight.
