Lighting

Although it can be considered as a basic human need alongside food, water and shelter, 1.6 billion people all over the world have no access to stable and safe source of light. It's a situation that two bright young Architecture graduates are aiming to combat with the LuminAID solar-powered lantern. Like the Solar Pebble initiative, the LuminAID lantern is designed to address dependence on kerosene lamps in the developing world and its extremely lightweight and easy to transport inflatable design is also targeted at use in disaster relief situations ... plus it makes a very handy addition to your camping kit.  Read More

With incandescent light bulbs in the process of being phased out around the world, LEDs are one of the most promising technologies for taking over our day-to-day lighting needs – they use less energy, provide more light, contain less toxic substances, and are tougher than incandescents. That said, they may not be the one and only best choice. Lasers are even more efficient than LEDs at high amperages, although scientists have long believed that the quality of white light produced by diode lasers would be unpleasing to the human eye. According to a study recently carried out by Sandia National Laboratories, however, the human eye appears to like their light just fine.  Read More

The arrival of high-intensity LEDs has certainly made a huge difference to the brightness of bicycle headlights. Some people, however, are now looking at using the bulbs not just as a means of lighting the cyclist’s way, but of making their bicycles more visible to motorists. A couple of examples include the Aura and Revolights systems, both of which incorporate LEDs into a bike’s wheel rims. Another system, that looks like it might be considerably less involved yet still effective, is called LED by LITE.  Read More

Perhaps you’ve performed that old camping trick before, where you created a lantern by shining a flashlight into a water-filled bottle. While that may have helped you find your marshmallows in the dark, imagine how much brighter that bottle would have been if it were lit directly by the Sun. Bright enough, it turns out, that it could brilliantly light up the interior of a one-room house. That’s the idea behind the Isang Litrong Liwanag (A Liter of Light) project – it’s bringing daytime indoor lighting to the homes of the poor in the Philippines, by installing water-filled plastic pop bottles through holes in their roofs.  Read More

In the past decade, LEDs have become increasingly popular for use on cars, mainly for use as turn signals, brake and park lights, and daytime running lamps, but more recently, also for use in headlights. Now BMW has revealed it is taking the next step in the development of vehicle headlight technology by working on the introduction of laser light headlights. The company says that laser light not only offers energy - and therefore fuel - savings, but could also enable entirely new design possibilities and light functions on vehicles to improve safety. It aims to have the technology ready for series production "within a few years."  Read More

The future of ambient lighting might lay in glowing walls, according to Philips. The company has announced its plans to develop wallpapers containing integrated LEDs. The luminous sound-absorbing textiles would glow in variety of colors accordingly to the user's requirements. To develop the luminous wallpaper panels, Philips is collaborating with customizable acoustic panels manufacturer Kvadrat Soft Cells, based in Denmark.  Read More

Combining lighting with audio by using a light socket to power a wireless speaker is a two-in-one approach that appears to be gaining traction and this latest example - the Sound of Light speaker - grabbed our attention on both the functionality and aesthetic fronts. The Sound of Light system uses a Texas Instruments 2.4 GHz Purepath Digital Signal Transmitter to set up a wireless link between an audio device such as an MP3 player, smartphone or tablet and up to four speakers within a 300 ft range.  Read More

Much has been written about the “internet of things.” Right now, not every human being has an IP but in the very near future, low cost smart chips will be added to every device to give it an IP address and everything in one’s life will become part of your private secure network to be monitored and controlled (and hence become smart) via a smartphone, tablet or PC. Earlier this week, Dutch-based NXP Semiconductors announced its GreenChip, which for the cost of about US$1.00, enables every light bulb to have its own wireless IP address. NXP has subsequently announced it is to make its JenNet-IP, ultra-low-power, IEEE 802.15.4-based, wireless network layer software available under an Open Source license in Q4, 2011. This development is very significant as it reduces the cost and greatly simplifies adding “smart” connectivity and two-way communication into a wide range of devices, and might well establish a cross-application standard for wireless connectivity in both residential and industrial environments.  Read More

Currently the brightest options for those looking to ditch their incandescent light bulbs in favor of the longer life and more energy efficient LED variety are those equivalent to 60 watt incandescent bulbs, such as the GeoBulb II. Things got a little brighter last month when California-based Switch Lighting announced its 75 watt-equivalent LED bulb and now the company has gone one better with the announcement of what it claims is the world's first 100 watt-equivalent LED bulb.  Read More
