LED light systems and device for locomotives and narrow beam and multi beam applications

An LED light system for locomotives and alike narrow beam, multi-beam angle applications comprising:

• an LED lamp having at least one LED cluster mounted on a thermally conductive enclosure with substantially transparent cover, the at least one LED cluster including multiple LEDs placed on a surface in close proximity for generating higher luminous stearance and attached to the thermally conductive enclosure, at least one LED of the multiple LEDs having at least one single external lens and at least one LED of the multiple LEDs having at least one two lens arrangement for
• collimating the light from the at least one LED for generating a desired directional beam for distant illumination and spatial distribution control;
• and
• a power source connected to said LED Lamp through an output unit, wherein:
• the output unit includes at least one under and over control means (UOM), at least one sensing means, and a multi-feedback means (MFM) connected to said at least one under and over control means operating on the feedback from said at least one sensing means, the state of the at least one under and over control means depending upon the input received from said at least one sensing means;
• and
• a first lens of a two lens arrangement is positioned close to at least one LED and acts as a light collector for collecting most of light exited from the at least one LED and direct the collected light onto a second lens of the two lens arrangement mounted for collimating the collected light and generating the desired directional beam.
