Now more and more municipal engineering began to use the LED street light, because the LED street light compared with common traditional street lamps have obvious good, normal traditional street lamps light source is using high pressure sodium lamp, the luminous efficiency of high pressure sodium lamp is low, and 360 are
at present, the municipal engineering in growing Numbers are beginning to use LED lights, because of the traditional street lamp LED street lamp is superior to the ordinary. Ordinary traditional street lamps using high pressure sodium lamp and overall high pressure sodium lamp luminous efficiency is lower, there are 360 lamp light, this is a great waste of electricity. In addition, the ordinary street lamps in use process will produce a lot of calories, short service life. Led lamp is a kind of semiconductor light-emitting diodes as the light source of street lamp. LED street light has the characteristics of high efficiency, energy saving, low power consumption. White light-emitting diodes (leds) power consumption is only 1/10 of incandescent lamp and energy-saving lamp of a quarter. The light emitting diode lamp light source does not contain harmful metallic mercury. The luminous flux LED street lamp light loss is very small. Different from the traditional light source, led street lamp is in the form of light. High pressure sodium lamp is a glowing light between all empty, so it is necessary to a half empty between the emergent light between the direction of change for the other half empty internal reflector reflects, at the same time inevitably absorbs light and stop the light source itself. Use led lamp as light source in this area will not cause any loss, square street light utilization ratio is higher than high pressure nano light.
