Very high visual comfort

ERCO has developed luminaires with special housing designs and highquality optical components specifically for demanding visual tasks to provide enhanced visual comfort.

Outstanding uniformity

To meet the stringent standards of vertical illuminance, ERCO has developed luminaires specifically to produce exceptionally uniform levels of illuminance.

Wallwashing for high rooms

Multi-storey spaces pose specific lighting challenges. Previously, wallwashers had to be mounted in very high-ceilinged rooms at a disproportionately great distance from the wall; however, the ideal position for the recently developed Atrium double-focus wallwashers is now at a distance of only one fifth of the height of the room.

Also suitable for sloping ceilings

As variants with a pivot angle of up to 30°, double focus downlights can also be mounted in sloping ceilings.

Covered or flush mounting detail

As standard, all recessed luminaires have overlapping installation details. Flush mounting rings are available as accessories.

Atrium double focus downlights are particularly suitable for use in high rooms. The lens systems generate narrow downlight distributions or, as wallwashers, create uniform vertical illumination, even at short distances to the wall. The black anti-glare cone provides particularly high visual comfort. The silver anti-glare cone is ideal for elegant integration in bright ceilings. For inclined ceilings, a recessed version is available that compensates for inclination angles up to 30°. In-house developed control gear enables uniform operating behaviour of luminaire groups and dimming down to 1% – perfect for auditorium lighting in cinemas, theatres and concert halls.

Atrium double focus: Light effect and planning aid

Lighting tool

Light distribution

Ambient lighting produced by wide beam light distribution.

Lighting technology
Luminaire arrangement

Downlights

Wide beam, rotationally symmetrical light distribution for general lighting. Good visual comfort in rooms with high ceilings.

Light source
6W - 112.1W
593lm - 13748lm
Downlights

Downlights

For uniform general lighting, the luminaire spacing (d) between two Atrium double focus downlights can be half the height (h) of the luminaire above the working plane (rough guide).

Arrangement: d = h / 2

Application area: rooms with high ceilings, e.g. foyers or event halls.

The wall offset should be half the luminaire spacing.

Arrangement: a = d / 2

Vertical illuminance for brightening and dividing the space.

Luminaire arrangement

Lens wallwashers

Asymmetric light distribution for very uniform illumination of high walls.

Light source
9.3W - 30.4W
836lm - 4074lm
Lens wallwashers

Lens wallwashers

Atrium double-focus wallwashers enable uniform illumination of high walls. The ideal spacing to the wall (a) is a fifth of the room height (h).

Arrangement: a = 1/5 x h

Application area: positioned close to the wall, these luminaires are ideal for atriums and foyers with room heights above 6m, but work just as well in rooms with lower ceilings.

For wallwashing with good and uniform horizontal illuminance, the spacing (d) of double-focus wallwashers may be up to 1.3 times the offset from the wall (a).

Arrangement: d ≤ a x 1.3
