Product Description
40cm round ceiling lights light colour adjustable Dali dimmable 30% indirect light UGR19
Completely new series of round dimmable ceiling lights with 40cm outer diameter and an approx. 30% light component that indirectly illuminates the ceiling and thus leads to a filling room effect. The round ceiling lights 40cm are available in the two colours black or white. The very reliable round dimmable ceiling lights use high quality SAMSUNG® LED chips and have an outer diameter of 400 mm and a mounting height of 86mm. (45mm illuminated area and 41mm inner mounting ring).
LED chips and have an outer diameter of adjustable light colour (Kelvin selector 3000K - 4000K- 5700K).
The light colour can be set to 3000 Kelvin warm white | 4000 Kelvin neutral white or cool 5700 Kelvin daylight white using the selector switch on the top of the ceiling light. In this case, 30% of the light emitted is directed upwards to the ceiling to create a room-filling effect. If desired, the brightness, which is around 2600 lumens, can be dimmed even further. You can read more about how to dim the light below.
2 different mounting options for 40cm round ceiling lights
The standard mounting of the round ceiling luminaires is direct ceiling mounting. This way, the 30% indirect light component is ideally used for a visually appealing and beautiful room effect. The inner ring is mounted to the ceiling and the body of the luminaire is attached directly to the ceiling ring after the electrical connection. The luminaire creates an impression of floating in the room.
The second option is an optional pendant suspension. In this case, the ceiling luminaire is suspended from the ceiling up to a maximum of 1.5m with the accessory pendant kit. The price of the accessories also includes a visually appealing textile cable for the electrical connection.
Suitable for office workplace / computer workplace with UGR<19
The structured, microprismatic luminous surface or glare-reduced version with UGR<19. This again ensures significantly lower glare and allows use in offices or workplaces with VDU workstations. A glare value of UGR <19 is ideal for glare-free and fatigue-free work. This complies with the specifications of DIN EN 12464-1 Lighting of indoor workplaces. In addition, flicker-free power supply units are installed, enabling ergonomic and trouble-free working.
40cm round ceiling lights 3 different dimming types in one luminaire.
This 400mm round ceiling surface mounted luminaire supports various dimming modes
1. dimming DALI via DALI-BUS
The DALI power supply unit complies with the latest DALI 2 standard. This enables high compatibility with many existing DALI bus systems. The power supply unit is ENEC and TÜV/GS certified and thus guarantees a high level of electrical safety. The LED driver can be reset to a slightly lower brightness with DIP switches as standard. The round DALI dimm ceiling luminaire is often integrated into large building or home automation systems via DALI or KNX.
2.dimming via PUSH dimming
The power supply unit is flicker-free and supports push dimming in addition to DALI dimming. Push dimming also runs via a dimming line and is ideal where it is not worth setting up a DALI network with a gateway due to the small number of luminaires.
3. 0-10Volt dimming via dimming line
With 0-10V analogue dimming, a thin control cable is needed and a suitable 1-10Volt wall dimmer. Dimming is very clean and even without flickering and flickering in the light. The minimum dimming is about 10%. In existing buildings, however, there is usually no 5-core cable for a dimming line! This often makes implementation in existing buildings difficult. The power supply unit can be reset with DIP switches to a slightly lower brightness if the basic setting is too bright and no complex dimming is to be realised.
The power supply unit is ENEC certified and therefore guarantees a very high level of electrical safety.
