Ecboo headlight

NEW DELHI: From April 2017, headlighttwo-wheelers in India will have to have a headlight that will light up the instance the engine is turned on. The government has issued the notification that all new two-wheelers manufactured in the country from next year to have a provision of automatic headlamp on (AHO) like Daytime camping lightsRunning Lamps found on cars.

Once this system is fitted in two-wheelers, riders won't have a switch to turn the headlight off as it would be automatic. Earlier, the Supreme Court-appointed committee on road safety had also pushed the proposal considering the fact that AHO has been found beneficial in reducing crashes involving two-wheelers in many parts of the world. This has been a feature in European countries since 2003.

Two-wheelers as a single category of vehicles accounted for the highest number of fatal road crashes (32,524) in 2014. Another 1,27,452 people were of instances where people on road (including riders) suffered injuries. Experts on automobile safety said AHO has improved visibility of and for two-wheelers during day and at dawn and dusk.

Sources said this visibility can be enhanced by optimizing the lamp's colour, luminosity and intensity.

some indication as to what lies ahead. Now researchers have developed a system that allows even more precise control through the ability to switch on and off any of 1,000 individual LED pixels.

Existing designs rely on up to 100 separate LEDs to provide individual sources of light, each with their own precisely aligned optics. Now, researchers at Germany's Fraunhofer institute have worked out a way to up this resolution to more than 1,000 LEDs, while still maintaining control over each individual pixel.

They were able to achieve this by connecting 256 pixels across four separate LED chips to a driver chip. Working with pixels 125 microns in size, they team discovered two ways to do this while ensuring a solid connection and sufficient cooling of the chip. The first technique involves a gold-tin alloy fitted to the chip in a fine grid structure with intermediate distances as small as 15 microns. The second approach instead relies on a gold, porous nano-sponge that can compress just like a regular sponge, allowing it to absorb any unevenness in the chip.
