Does your control equipment require 24/7 power supply?
No. All our equipment can be powered off for the day without problems.
I already have a central management system to control my lighting infrastructure. How does Lumine fit in with this?
Our system is designed so that it can sit on top of any control system which is based on switching the power on and off at the electrical cabin level. In such a case you can see our system as a way to optimize the amount of light offered in your lighting infrastructure. From your current management software you are able to see reduced power consumption in the cabins that power luminaires equipped with our system.
If your system has wireless light fixture specific controllers, the deployment of our system would require you to uninstall the present wireless controllers from your luminaires.
We will also introduce interoperability with equipment and software from other devices.
What happens if one control device is broken down?
The luminaire with the broken device and adjacent luminaires returns to full power.
What dimming interfaces does your system support?
We support dimming by both DALI-protocol and a 0-10 V analog voltage.
Are all led-luminaires compatible with your system?
A vast majority of modern led-luminaires are compatible with the dimming interfaces we support. Some luminaires however utilize programmable drivers with the dimming interfaces disabled by default, even though they are marketed dimmable. To be sure, you should always consult your luminaire provider about compatibility before starting a project.
I want to utilize your system to control my old luminaires (mercury vapor, high pressure sodium etc.). Is this possible?
It is possible if your luminaires are equipped with dimmable electronic ballasts. Generally if they are not equipped with dimmable ballasts, we would suggest that you rather invest in LED’s than retrofit existing luminaires with dimmable ballasts.
You utilize PIR-sensors. Wouldn’t radar-technology be more reliable?
PIR-sensors are based on measuring the temperature difference between ambient and objects. This makes it reliable in outdoor solutions where heat sources other than humans, animals and cars are rare. Radars instead are based on detecting the changes in frequency between transmitted and received signal, also known as the Doppler-effect. To detect slow moving pedestrian the sensor has to be set up to trigger on a small change in frequency, which makes it vulnerable for swish of tree leaves caused by wind. So in general PIR-sensors are more reliable than radar in outdoor applications.
Do little animals cause false motion detections?
Animals the size of mice or squirrels does not cause motion detection. To verify reliable detection of humans and cars, slightly larger animals such as larger hares cause false motion detections. In our current installations, the false detection rate averages in less than 5 % of verified detections.
You utilize mesh-networks. Does this mean that the individual control devices do not have to be in range of the Master-device?
Yes, each individual control device is capable of routing messages to other devices. Due to this each added device extend the effective range of the network by approximately 100 meters.
So how long apart can the control devices be from each other?
Maximum reliable range is 100 meters, so the lighting fixtures should not be located further away than this.
Does the network survive if a control device is broken down?
Yes, if there is one device broken down, the messages are re-routed so that the broken device is skipped.
Isn’t the 2.4 GHz frequency band too crowded?
The 2.4 GHz frequency band is split to many small slots. Some of these slots are relatively crowded by Wi-Fi networks close to city centers. We utilize IEEE 802.15.4 standard, which defines an extremely narrow band compared to Wi-Fi. This allows us to utilize those slots that are not crowded by WiFi.
What happens if the internet-connection to the Master-device is broken?
The system continues its normal operation. The receiving of motion detection and other measurement data to the Manager is delayed until the internet-connection has been re-established. If settings are changed when the Master-device seems to be offline, the new settings are uploaded immediately after the internet-connection has been re-established.
