LED recessed ceiling downlights

for external on/off or DALI power supply units · Direct and indirect light


Downlights with direct and indirect light.

Luminaires with hand-blown opal glass with various LED outputs, half beam angles and dimensions for installation in suspended ceilings. When the appropriate installation housing is used, the luminaires are suitable for installation in concrete ceilings.

A focusing/diffusing lens made of crystal glass bundles the efficient light in the centre of the reflector for downward-directed light. At the same time, part of the stray light is used to illuminate the luminaire glass and to produce a degree of vertical illuminance.

The luminaires are available with fixed or variable colour temperature (tunable white).

By adjusting the colour temperature you can adapt the illumination perfectly to your lighting requirements or to the required mood. Colour temperatures of between 2,700 and 6,500 K can be selected, perfectly covering the colour temperature range that is felt to be ideal.

When making the recessed opening in concrete ceilings, it is advisable to use an installation housing. Installation housings are accessories and must be ordered separately.

Luminaires with fixed colour temperature can be optionally connected to an on/off power supply unit or DALI power supply unit by means of simple plug connectors. External power supply units for operating these luminaires are accessories and must be ordered separately.

Luminaires with variable colour temperature (tunable white) are delivered complete with an external DALI power supply unit. They can be controlled by DALI colour light control (DT 8, TW). We recommend our BEGA Control system for this purpose.

LED colour temperature tunable white luminaires adjustable from 2700 K to 6500 K

The required installation depths can be found in the instructions for use for these luminaires.

The luminaire luminous flux and the luminaire connected wattage quoted in the table might change as a result of technical progress. On our website you will find data sheets with information on each luminaire concerning not only the current values but also the LED service life and the luminous flux in relation to the respective colour temperature.

Planning examples

On the basis of our empirical values and the suggestions of architects and planners, we have compiled room situations for which lighting design is frequently required. In the following, we shall present possible illumination solutions for these architectural situations. It goes without saying that all technical lighting standards are complied with. In some cases, the degree of illuminance proposed by us may even exceed the standard. For us, the aesthetics of light and a high level of visual comfort are important criteria for such decisions. At the same time, the form and the size of the luminaires must fit into the architectural surroundings. For example, we often recommend larger models if a structure has large dimensions – even if smaller luminaires with lower output would be enough. In such cases, the degree of illuminance can be reduced to a suitable level by means of a light control system.


Lobby

We are entering the foyer of a hotel. We are welcomed by pleasant mood lighting. Sculptural pendant luminaires made of polished aluminium and thick-walled crystal glass illuminate the reception desk. Such lighting draws the attention to the reception. This combination of materials is repeated by other luminaires in the room. The reception area for the staff is bathed in light...

Conference room

The conference room is flooded with daylight through a large window. If required, this window can be darkened. Downlights in the ceiling illuminate the room uniformly and create a pleasant degree of illuminance of 500 lx on the table. On the end wall of the room, there is a presentation screen which is illuminated with surface washers from the ceiling. To be able to work with different media...
