Traditionally light-focusing systems have consisted of either a lens, or a reflector.We are pull together the strengths of the lens and lens into one combined system, then achieve more clear, more focus for long-distance viewing and bring more light output.
We have own patent in USA and China
Patent application number: USA 14/010,036

As picture:
Single lens have the advantage of emitting a homogonous light pattern for up-close reading, yet over long distances luminous flux is small |

 |
As picture:
Double lens structure can make the LED light beam angle become smaller,then through the same area irradiation on the reference substance,then the luminous flux will increases accordingly |
