This article (“An illuminating experience”) mischaracterized TransLight Corp.’s new LED products. TransLight is readying a new patent pending LED headlight for locomotives and other train maintenance equipment. The patent covers the use of this device for all other similar headlight or lighting devices that benefit from projected beam patterns applications, rather than bright surface illuminations with limited projected beam patterns.
At this time, TransLight believes that projected beam patterns are essential for train and vehicle traffic control signal for penetrating inclement weather conditions, and with incandescent lamps lasting up to 50,000 and 100,000 hours, the extra cost for LEDs may not be justifiable, especially with the railroad paying a much higher cost for replacing failed LEDs vs. incandescent lamps.
Therefore, TransLight has a patent pending reflector that mounts on the generic incandescent lamps for wayside color-light signals that increases the beam pattern candela by up to four times. They also have designed a patent pending LED with a miniature reflector that mounts into existing lamp sockets and has a focal distance that mates with the existing designed optical color light lens set of existing color light signals. This concept means only the lamp will be replaced with the reflectorized LED configuration, thereby saving railroads the cost of replacing signal fixtures or lens sets.
