Would You Be Interested in a Design Challenge on Sensor Integration in Lighting?

rscasny
rscasny over 3 years ago

I spend a good amount of my week in meetings with our suppliers. We talk about what activities that they can bring to element14. And I do a lot of listening about what interests them and try to match it up with what I think its the element14 community. The results of the discussions often bring sponsored activities in the Design Challenge, Roadtest, and Essentials areas of the community, among others. 

One area of interest for our suppliers is lighting. This can include street lighting, indoor lighting and outside lighting. I think the migration from incandescent or fluorescent lighting to LED lighting is one example of their interest. )I hear about Horticulture Lighting more than you think!) They see the benefit of energy savings, while I would say you can do a lot of things with LED lighting. Some of our suppliers are putting out dev kits. So, it's an area of substantial interest.

Currently, I am speaking with a supplier who is interested in sensor integration in lighting. I suppose this phrase can mean various things. For me, it means two things: (1) the ability to run the sensor data output through the lighting system and (2) the ability to have the sensors control the state of the LED in an office or building. It could be something as simple as temp sensors or object detection/human presence sensors that would turn the lights off when no one was in a room for a designated period of time. Of course, there are many other applications or ways one can play with LED lighting. 

I'm trying to get your feedback on your interest in participating in an sensor lighting integration challenge? If you aren't, that's fine. If you are, what would you need, materials-wise.  I'm guessing the materials could include a control board, LED Driver, LEDs, Sensors, Connectors, LED fixtures, etc.

    Yes this would be an interesting design challenge. It's probably done already within office buildings but I always wanted to use a LUX sensor in combo with my LED desk lamp. In winter, for example, I would…

    I’m thinking more along the lines of tech-enhanced art these days, so I might try to set up motion or gesture sensors that trigger a series of LED patterns to light up within a painting or sculpture. Or…

    It would be interesting - I know there are some that are focusing on energy efficiency so they are using ambient lighting sensors to adjust the output of dimmable LED panels. It's a good idea, but how well it works in practice is another thing. Whether there is perceivable modulation of lighting and the response speed would be of interest. I think that something as simple as a lux-meter or even ambient light sensor module could be used to explore the intensity at a work surface under varying conditions of the day. Looking at the communications between sensor and luminaire may also be interesting.

    Colour temperature changing would be interesting too, but I wonder how well that would be implemented. Perhaps knowing sunrise/sunset times and using that without sensors could be enough for just colour temperature changing assuming the luminaire has a mixture of different white LEDs (or full RGB/W).

    I'd be interested, but we'll need 230V-rated luminaires here and any radio-based equipment will need to comply with local laws. I wouldn't imagine you shipping a 1.2m office ceiling troffer all the way down here ...

    "...Colour temperature changing would be interesting too, but I wonder how well that would be implemented..."

    This is often an issue when working with video cameras in rooms where mixed colour temperatures and levels are an issue when panning the camera around a room. Often in a meeting or seminar rooms you can end up with a mixture of tungsten, fluorescent, LED and daylight (oh and don't forget the projector / LCD screen light source too) all at different colour temperatures and brightness levels. Would be nice for light sources to play nicely together. Not only does it help the camera but it also can reduce eye-strain.
