LED lights and traditional high pressure sodium 200 watts of solar light how much light contrast

LED lights and traditional high pressure sodium lamp lights, LED street lamp USES the low voltage dc power supply, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, can be widely used in road. Resistance to high temperature of 135 degrees, the low temperature of



the LED street lamp' LED street lamp is made of street lamp, LED lamps and lanterns with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, the city lighting energy saving is of great significance. 】 Unlike traditional high pressure sodium lamp lights, LED street lamp USES the low voltage dc power supply, safety, energy saving, environmental protection, long service life, fast response speed, color rendering index [ Light source for color is called color rendering of the object, is by reference or reference light source with same color temperature ( Incandescent lamp or light) The comparison of the object color appearance. 】 Higher unique advantages, can be widely used in the way. Resistance to high temperature of 135 degrees, da at low temperature 45 degrees.

the LED street lamp advantages:

1, the characteristics of itself - — The unidirectional light, no light diffusing, guarantee the light efficiency.

2, LED street lamp has a unique secondary optical design, LED street lamp light to the lighting area, further improve the efficiency of the light, in order to achieve energy saving purpose.

3, LED has reached 110 - 130 lm/W, also has the very big development space, and the theoretical value of 360 lm/W. And high pressure sodium lamp luminous efficiency was increased with the increase of power, therefore, is better than high pressure sodium lamp LED street lamp lighting in general; ( The overall smooth effect is theoretically and actually 250 w high pressure sodium lamp light efficiency is higher than on the led street lamp manufacturers led lights) 。

4, LED street light light color rendering many higher than the high-pressure sodium lamp and high pressure sodium lamp only around 23, color rendering index and the LED street light color rendering index above 75, think in terms of visual psychology, to achieve the same brightness, LED street light can an average of more than 20% lower than the high-pressure sodium lamp,.

5, light failure is small, light failure is less than 3% a year, still meet the requirements of the road to 10 years, and high pressure sodium light failure is big, has fallen by more than 30% a year or so, therefore, the LED street light on the design of the use of power can be lower than the high-pressure sodium lamp.

6, LED street light automatic control and energy saving device, can realize under the condition of meet the requirements of different times lighting the biggest possible to reduce the power, saves the electricity. Can realize the computer dimming, period and control, light control, temperature control, humanized functions such as automatic inspection.

7, long service life: can use more than 50000 hours, provide quality assurance for three years. Deficiency is the power of life is not guaranteed.

8, high light efficiency: the use of more than 100 lm or chips, compared with traditional high pressure sodium lamp energy saving more than 75%.

9, installation is simple: don't need to add buried cable without rectifier, etc. , will be installed directly on the light pole connected to or nested original lamp shell.
