Led street lamp PK traditional high pressure sodium lamp

- -

LED street lamp with directional light, low power consumption, good drive performance, fast response, high seismic ability, long service life, green environmental protection advantages of gradually into people's horizons, to become the world's most currently have alternatives to traditional light source advantage of a new generation of energy-saving light source, therefore, LED lights will be the best choice of the road lighting energy saving reconstruction. LED street lamp which semiconductor lighting, light emitting diode as light source, because it is a solid cold light source, green pollution-free, less consumption, high luminous efficiency, long service life, etc.

the LED street lamp with conventional high-pressure sodium lamp lights, high-power LED street lamps light source adopts low voltage dc power supply, by GaN power type blue LED yellow phosphor synthesis efficiency white light diode, with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, can be widely used in urban road lighting. Housing available PC control, high temperature resistant degree, low temperature resistant da Degrees.

the contrast between them:

. Light utilization efficiency, luminous rate

the luminous flux LED street lamp light loss minimum, unlike traditional light source, LED lamp is half space light emitting light. High pressure sodium lamp is illuminated light source, whole space needs to be one and a half space of emergent light reflector to reflect changing direction to the other half space at the same time, inevitably, to absorb the light and the light source itself. And use leds as the light source, no losses in this regard, light utilization ratio is higher than high pressure sodium lamp. Leds are currently - lumens per watt, and high pressure sodium lamp lumens/watt can be achieved. High pressure sodium lamp spectrum is more focused on yellow, color temperature - K in the fog. Sodium lamps and lanterns has a very big problem, the sodium lamp lighting sustainability is very bad. Sodium lamp under the working condition, the temperature of the cavity in the body of lamps and lanterns than degrees, and is the % of high pressure sodium lamp, LED lamp temperature in non-work state because of the negative pressure to suck in so much dust and insects, greatly affect the effect of light and life of sodium lamp. And the LED is stable.

. More

LED lights on the energy conservation and environmental protection high efficiency and energy saving, low power consumption. White LED/power consumption only for incandescent lamp, energy-saving lamps /. And the LED light source does not contain harmful metallic mercury. High pressure sodium lamp light source in the metal containing mercury, sodium metal ( After electrify into mercury vapor and sodium vapor) , short life, Relative to the LED) , the subsequent waste treatment for environmental pollution. LED lights good vibration resistance, the transportation is convenient. Solid-state encapsulation, belongs to the cold light source type. So it is very easy to transport and install.

. On the structure and the cost is

LED lamps and lanterns of particles are commonly are obvious, and its luminous position more concentrated. So the LED need to do a better design on all light, point light extend as far as possible into surface light source, improve the comfort of the eye. Then there is a lot of products can do LED dimming design, to save energy. At present, most manufacturers design and manufacture of LED street lamps and lanterns, its weight very heavy, often more than kg. Such a big bear the gravity tends to make the light pole, reducing its ability to resist wind. Most of the manufacturer of LED lamps and lanterns, all designed to replace the way to LED lamps and lanterns, namely, directly replace the existing lamps and lanterns. And to do the current of the LED to reduce the wick in the case of maintaining the brightness number to save costs, or compressed PCB area.
