The plant layouts of the refinery and oil tank plant are extremely complex, with not only major light barriers but also working surfaces of different heights.

.

Floodlights at high altitudes are installed at several locations outside the hazardous area to provide lighting for safe walking and some piece counting tasks. In other places where this system cannot provide sufficient illuminance, some scattered local lighting fixtures, such as stairs, aisles, valves, and metering areas, need to be installed.

The installation location of these lamps should be carefully selected to avoid glare when viewed from different horizontal directions. Most of the local lighting equipment has bulkheads or well-shaped glass frames, and uses high-pressure or low-pressure gas discharge lamps, and needs to be compatible with the operation and the hazard level of the materials in the area.

Cargo loading and unloading area and stockyard lighting requirements

These areas are mostly used for the storage and transfer of containers or other large goods, so light barriers have once again become a major design issue. Since most obstacles are movable, fixed local lighting equipment cannot be used.

In addition, the movement of cargo trucks, forklifts, lift arms and gantry cranes must also be considered. Floodlights installed on high poles, high towers or construction sites can provide general lighting for locomotives on rails, vehicles on roads and the safe actions of workers, while local lighting for cargoes is installed on crane racks. The project-light lamp on is completed. Because there will be vibrations at these locations, gas discharge lamps with better seismic performance are more suitable, but it must be noted that the fluctuation range of the control voltage cannot exceed the standard of the lamp, otherwise the lamp is extremely prone to damage.
