Public lighting :LEDs or UV mercury vapours lamps ?

The public and industrial lighting faces a new challenge : to put together thousands of LEDs or to improve the old UV mercury vapours lamps.The streets of the cities must be good lighted and the industrial parks too.What is better , to glue huge surfaces of thousands of LEDs or to apply innovations to enhance the efficiency of the old lamps.A new invention made by Mr. Ion G Nemes from "nemes-invent" seems to put more emphasis on the old methods but renewing them.The new mercury lamp described in WO/2008/072990/Fluorescent light emission structure...,claims to achieve the halving of the energy consumption by a new bulb fluorescent surface and by a new UV burner made of two concentric quartz tubes and two ring shaped electrodes .The inner tube is reflective coated on its inner surface.Reducing the cross section of the electric discharging at the ring surface between the two tubes ,the electric current is also reduced and on this way the consumed power. Nobody interested to produce high efficient lamps ? DOE ,EPA or maybe NYSERDA ? Or private investors ?nemes.invent@gmail.com
