Experts at the Karlsruhe Institute of Technology (KIT) in Germany created a new type of LED light that is low on power use, more efficient, safer, cooler, and pleases the eyes.
The team created the new array of LED that would be a good candidate for street lamp use. Though, the use of LED may have pros compared to HID lamps, these form of illumination still have issues.

One of those is that LED lights have chained diodes. Meaning, if one goes out, the whole circuit does, and the more there are on one connection, the higher the voltage needed to power them. With the maximum permissible contact voltage being set at 120 volts, that limits the number of connected LEDs to 40.
Thus, KIT's Light Technology Institute came up with a method to inter-connect the LEDs, allowing for the circuit to stay lit up if individual diodes fail. This technique lets more LEDs installed. In fact, with the KIT prototype consisting of 144, it can run much more efficiently, at a tested 20 volts.
These low-power LEDs also use less electricity, they are as well cheaper to use despite of more lights being installed. The lights also accumulate less heat due to the even distribution of temperature, thus avoiding overheating.
"Many small LEDs are perceived as panel radiators from a certain distance," Michael Heidinger, inventor of the new system said in a statement
. "Their glaring effect is smaller than that of high-performance LEDs that are perceived as spot-like light sources."
Industry partners like Gratz Luminance are already working on this technology. Final products may be out later in 2017.
"For the first time, we can now construct glare-free lamps of high efficiency, which meet highest safety standards," Klaus Müller, Managing Director of Gratz Luminance told Newatlas
. "Before the end of this year, we will make available our lamp to customers for testing purposes."
