LightDim is the next revolution of LED Lighting Market, offering a more efficient, reliable and smart solution, creating new communication interfaces between citizens and machines.
The standard durability offered actually for LED Lighting Manufacturers is around 50.000 hours, though in some cases it can be granted up to 75.000 hours, the main solution most implemented to avoid overheating of LED Bulbs has mainly been based on aluminium foil designs, allowing a greater heat dissipation but including its corresponding cost overruns
LightDim is a remote controlled small device for LED lighting. Its mission is to optimize the function of the lamps offering greater durability and a full range dimming from 0 to 100%.
LightDim develops specific codes which enables the refresh of LED bulbs by means of inserting at a very high speed on and offs, so they can be refreshed without any discomfort to human eye, therefore, although the dissipated heat is the same, the maximum temperature obtained is reduced.
Accordingly, intensity lighting level of LED Bulbs can be controlled by changing the work cycle of signal excitation in a complete range from 0 to 100% in each one of luminaries, allowing to intensify in an exclusive way only those street lightings located in critical areas as crossings and intersections, while the rest of the lighting circuit can be reduced their range dimming just at security levels.
The added value of this application is that the light output can create optical wireless signaling networks through traffic lights and street lighting systems, without interference or noise associated electromagnetic fields, interacting with citizens, persons of reduced visibility or tourists and giving a new meaning to smart cities.
A new concept for Smart Cities
LightDim allows converting streetlights and traffic lights in a huge smart grid for pedestrians, tourist or blinds. This application, awarded by Vodaphone in 2010, offers a navigation system for Blind People by means of led light beam.
- Allows the blind to perceive the state of a semaphore (could be any other element of urban signage)
- Avoids uncertainties and prevents system noise
- Provides guidance aids located within the city
- The audio message from the receiver can be adaptable to any language
- SINAI use other external light sources (lamps, neon signs) or indoors (lighting in hallways of buildings).
- Creates an optical smart grid like a “GPS” virtual (even where conventional GPS fails)
