LED lamp – a semiconductor device that converts electric current into light radiation. In led lighting, as opposed to incandescent or fluorescent lamps, electric current is converted directly into light radiation, with significantly lower losses in the generated heat. led lamp emits a narrow part of the spectrum, the color is pure, which is especially appreciated by designers, and ultraviolet and infrared radiation, are generally lacking. led lamp mechanically robust and extremely reliable and its service life up to 100,000 hours, which is almost 100 times greater than that of incandescent lamps, and 5 – 10 times greater than that of discharge. Finally, the led – a low-voltage electrical appliance, and therefore, safe. led technology allows for more than three times the cost of electricity and requires no maintenance costs for Compared with conventional lighting systems and appliances. Efficiency and energy conservation using led lamps for street lighting will be completely re-equip the city streets on a new source light close to natural. The main differences of led lighting technology from the tube: All tubes, traditionally used in street lamps give light in a radius of 360 . These bulbs consume 80% of energy on its own heating. Luminaries such lamps have reflectors to create the desired direction of radiation, which lost about 35% of the luminous flux due to loss of light emitted by the reflector. Frequent past while modernization by replacing incandescent lamps drl on hps lamps, or dnz when the same power and declared a high efficiency, does not lead to real savings.
