High Pressure Sodium Light vs LED Street Light2Jare2012-04-26 02:15:55
High Pessure sodium lamp spectrum are relatively concentrated in the yellow, the color temperature is only 2000 - 2500K, but the temperature of the LED lamp color is greater than, until 3500 - 4500K or more. Sodium lamp high Pessure starts around much of the light can not reach the road. Sodium high rate Pessure Lamp color is poor, only 20 to 40, and lightheadedness, but the LED is much higher, you can get to 75-80, so the road looks bright and comfortable illumination of sodium lamp high Pessure. From the practical standpoint glow, the LED lamp is much higher than the high sodium lamp Pessure. 100W LED lamp can replace the 250W sodium lamp high Pessure. 100W LED lamp output only about 6250 light output (missed something across the optical design of a second), but you can get the light output 6000, when he reached the road, and can reach 16Lux (pole 12m high lamp ) of the mean. 250W high pressure sodium lamp output Pessure of l20, 000 lumen, but the road to reach only 7,000 light output and only about 30 40Lux for the average. Because the coefficient of difference of color, LED illumination lamp correction factor is 2.35 times the sodium lamp high Pessure is only 0.94 times. After checked 100W LED lighting of the lamp is 37.6Lux the road, while the sodium lamp high Pessure is 28.2-37.6 Lux. Both pretty. Therefore, the LED lamp of 100W can replace the sodium lamp of 250W high Pessure. LED lamp can save energy of 2.5 times the sodium lamp high Pessure. In addition, the LED lamp has a long life. High Pessure sodium lamp life of 20,000 hours is designed, but due to voltage variations and the impact of high starting current, real life is less than 2 years. Therefore, the actual duration of life is usually only 4000 hours, assuming 10 hours per day, 400 days can only work. A little over a year to replace the lamp, while high power LED lamp life is 50,000 hours, assuming 10 hours of work each day, after thirteen and seven tenths to be replaced.
