c.V. by _tngc from uk

c.V. is an interactive lighting that shows optical illusion to the users. The optical illusion is stroboscopic effect that is one of the famous optical phenomenon. Stroboscopic effect causes the phenomenon that the moving objects becoming to be seen as stopping or moving backwards by high speed blinking of the illuminant. It is often seen in the movie that the wheels are seen as moving backwards or the extractor fans are sometimes seen as moving backwards or stopping with sunlight coming in.
The human is known as being largely depending on the visual information in the five senses. I think very few people wonder whether what they see with their eyes can actually be taken as an accurate perception or not. However, illusional phenomenon can easily take place at any time in our daily lives. Various phenomena caused by optical illusions serve to remind us that we should not always believe our visual sense. I designed this lighting fixture with the aim of creating a product that makes us aware of the vulnerability of the world we see.

c.V. has three high power LED as illuminants and a human detecting sensor, three small unimorph water pumps. When there is no human around it, it continues to illumine with dimming like repeats getting bright and dark slowly. Once human coming it detects them by the sensor and starts the continuous flash that causing stroboscopic effect. Also waterdrops drip from three nozzles beside the illuminants. We can see the situation that the waterdrops are in static state in the air or going upward as optical illusion because the illuminants repeatedly change its flash frequency.
It’s much effective to see the stroboscopic effect in the dark environment but even in the bright place we can see the effect if there is something synchronously moving with frequency of the flashing illuminants. The reason that I’ve designed it integrating with waterdrops is waterdrops can play a part for showing the effects effectively and its beautiful attractiveness that the waterdrops look like sculpture when it’s in stationary situation.

The concept of this lighting fixture is quite experimental and I think it may seem to be an artwork. The interactional factor that it reacts to the human and causes the stroboscopic effect and the its styling emphasize the biologic presence. As a reason I chose the stroboscopic effect, there are large impact for visual sensation and attractiveness of dynamism that change the space drastically. I thought this effect could be a effective way for raising user’s awareness for the fact that lightings in daily life have large effects for our visual recognition. For me this is a challenge for the future potential of next generation lighting fixture. What kind of things the lightings can do? In the field of media art installation, quite often we have seen interactive works using lights or lighting effects. However almost lightings in our daily life are still static and quite traditional. I’ve imagined we can gain great feedbacks as a coherent package from the interactive artistic sector that has done a lot of experimental trials with technologies. As a result, c.V. has a mixed character that the element of interactive artwork and the element of device as a product.
