Fuel stations

What the facility needs

A fuel station is three tasks on one site. Under ShNK 2.01.05-24 the dispenser area under a canopy takes 75 lx on the surface and 50 lx on the pump display (app. 9, table 2, item 3a), filling and unloading points 20 lx, entrances from the street 15 lx, the rest of the site 10 lx (table 21), the shop and checkout 300 lx (app. 9, table 1, items 79, 85). Fuel retail chains put noticeably more than the norm under the canopy in their own standards, and then we design to the specification.

A separate requirement is contrast: beyond a brightly lit canopy the driver sees nothing. So the area around the canopy is lit as well.

Why these series

Classic covers the forecourt and the driveways: bracket mounting on a column, IP65, installed at 4 to 10 m.

Line goes under the canopy: an even field of light above the dispensers without glare sources in the field of view. Under the canopy is a sheltered zone, with no jetting water and no dust storms, so the Line housing is IP54, not IP65. On this site IP65 is carried by the outdoor Classic units on the columns, the ones that stand under open sky.

Typical layout

A station with a canopy of ≈ 300 m² and a forecourt of ≈ 600 m²:

• under the canopy: SVO 01 Line 50W, ≈ 24 pcs
• forecourt and entrance: SKU 01 Classic 100W on 6 m columns, ≈ 6 pcs
• ≈ 30 luminaires in total, installed load ≈ 1.8 kW

The flux is calculated: Line 50W 7,000 lm from the module in the Line series file (1,400 lm per 10 W), Classic 100W 13,000 lm per the header of the 2018 IES file (the file itself does not agree with its curve). Utilisation factor method with MF 0.63 (app. 1, table 3, outdoor areas; safety factor 1.6, MF = 1/1.6): under the canopy with UF 0.5, 24 × 7,000 × 0.5 × 0.63 / 300 ≈ 175 lx, which covers both the 75 lx target and the 150 lx that chains typically ask for (the target alone would take ≈ 12 pcs); the forecourt with UF 0.3, 6 × 13,000 × 0.3 × 0.63 / 600 ≈ 25 lx against 20 lx at the dispensers and 10 lx elsewhere. The count depends on the number of dispensers and the height of the canopy.

What the replacement gives

Before: the same station on 18 HPS 250 W lamps at 275 W with ballast, ≈ 5 kW; at the nominal lamp flux (30,000 lm, Lisma) that is ≈ 540,000 lm on the site.

After: ≈ 1.8 kW and a calculated ≈ 246,000 lm: fewer lumens, but the light lands where the target is, under the canopy and at the dispensers, not into the sky and onto the neighbouring plot. At 12 burning hours for 365 days a year the difference is ≈ 13,800 kWh a year; in UZS, by the tariff on the date of the calculation (see the savings calculator).

A calculated estimate under the stated assumptions, not guaranteed until measured on site. Illuminance on the surface comes from a DIALux calculation against the site plan.

Built for the heat

A canopy heats up all day: the luminaire under it works at the hardest point on the site. The aluminium housing carries the heat away.
