LED光源与高压钠灯光源对比分析

LED路灯与传统灯的眩光、色温与显色性对比

Comparison between Lens Flare, Color Temperature, and Color Rendering Index of LED Lamp & High Pressure Sodium Lamp

200W传统灯

200W High Pressure Sodium Lamp

60WLED路灯

60W LED Street Light

在同等的照度下两种光源比对效果。对比可以发现,在同等光照下,白光LED路灯显色性好,物体清晰可辨;而高压钠灯尽管光线很足,但显色性差,物体原色的视觉还原能力差,所以,在同等照明效果下白光LED光源所需要的照度值可底一些。

Under the same level illumination, the Color Rendering Index of white light LED Lamp is much better that the objects are very clear to distinguish, while, though the High Pressure Sodium Lamp is also very bright, its Color Rendering Index is very poor, the vision for objects’ primary color is bad! So at the same level illumination, the Luminous Lux of white light LED source could be lower than the traditional lamp.

LED路灯耗电低/运行费用低

Low Power Consumption and Cost of LED Street Light

NS01

As picture NS01, NSRL-005 E40 100W LED Street Light ( Below One) equals to the 250W High Pressure Sodium Lamp (above one, the actual power consumption is 290W.)

Comparison diagram for 2 years Power Consumption of LED Street Light & High Pressure Sodium Lamp (10 working hours per day):

可以看出:采用LED路灯替代传统路灯每年每盏路灯节约600度电,如果每度费为1元,则每年每盏LED路灯节约的电费为600元如果某个城市装有1万盏传统路灯,那么全部更换为LED路灯后每年节约600万度电;如果每度为1元,则每年节约电费600万元人民币。所以采用led路灯照明替换传统路灯照明可以大大降低运营成本。

From the above picture we could see that each LED Street Light could save 600Kwh power per year, if the power cost is 0.2USD/Kwh, then each LED Street Light could save 120USD; if there 10000PCS traditional lamp will be replaced by LED Street Light, then could save 6 million Kwh power per year, and 1.2 million USD. It’s obvious that using LED Street Lamp could save very big cost.

铜电缆使用量少/建设投资底

Low Use of Copper Cable and Investment

某城市在100公里的新建道路上安装1450盏路灯,灯杆间距为35m,灯杆高度为10m,双侧布置,没杆单灯头。如果安装标称250W的高压钠灯(启动电流高达4.54A),那么在正常的1.5公里布置1个变压器的情况下,通常选取杆间铜线缆为4X35m²,价格为人民币¥12/m。而如果安装朝鹏100W的led路灯,那么可以选取杆间铜线缆为4x10mm²,价格为¥28/m;杆内铜线为1x1.5mm²,价格为¥5/m。下图给出了传统高压钠灯和LED灯照明的铜材消耗量情况对比如下图:

Install 1450PCS street lamp on both sides of a 100 kilometre new street, distance between lamp pole is 35m, height is 10m, if use High Pressure Sodium Lamp(Start-up current 4.54A), then it will use 4*35m²Copper Cable on the normal situation of on the distance of 1.5kms to install one transformer; while, if NSRL-005 100W LED Street Light, then it will only use 4*10mm²Copper Cable between poles, its 4.2USD/M; and 1*1.5 mm²in the pole, its 0.75USD/M. The below picture is comparison diagram for Copper Consumption between LED Street Light & High Pressure Sodium Lamp:

传统高压钠灯和led灯照明的铜材资金投入情对比

Comparison diagram for Copper Investment between LED Street Light & High Pressure Sodium Lamp

通过比较可以发现,新建道路伊始即采用LED路灯照明将节约铜材206.7吨,减少铜电缆支出938万元。此外,led路灯照明方案还能减少变压器的使用数量以及工程施工量。所以,即使LED路灯较传统路灯价格要高一些呃,但综合路灯、铜线和变压器三部分的投入,LED路灯整体照明方案与传统路灯照明方案的建设投资基本持平甚或底一些。

From the above comparison we could find that to use LED Street Light on the new street we could save copper 206.7tons, and 1.41million. Otherwise, we could reduce use of transformer and the project construction. So integrate the investment of lamp, copper cable, and transformer we could find out that the construct investment of LED Street Light illumination is almost the same as traditional Street Lamp illumination , even a little lower, though the cost of LED lamp is higher than the traditional Street Lamp.

工作寿命长/路灯更换成本底

Long Lifespan & Low Replacement Cost

The lifespan of LED Street Light is more than 2.5 times of High Pressure Sodium Lam’s. Each High Pressure Sodium Lamp need to be replaced per 2 years, while, the LED Street Light is no need maintenance for continuously working 5 years. The below picture is comparison diagram for lifespan of LED Street Light & High Pressure Sodium Lamp

资源节约/环境友好

Resource conservation & environment friendly

采用Led 路灯照明,除了带来可观的经济利益外,还会带来巨大的社会效益。一万盏250W高压钠灯在采用Led 路灯更换后每年可以节约600万度电。

Uses the Led street light illumination, besides brings the considerable economic interest, it will also bring huge social efficiency.  Every year could save 6 million Kwh power after replacing 10 thousand High Pressure Sodium Lamp by LED Street Light.

So much power conservation means the reducing of coal use, and also reduce the waste of sulfide and carbide. The below picture shows each resource conservation and the reducing waste after replacing 10 thousand High Pressure Sodium Lamp by LED Street Light.

智能化程度高

High Intellectualization

因为Led 光源是通过PWM方式进行驱动,所以一些智能控制功能比如分时控制、声光控制、网络控制、无线控制及自动适应控制等都很容易实现。

As the driver of LED source is carried out by PWM way, that makes some of the intelligent control function such as time control, acousto-optic control, network control, wireless control and automatic adaptive control realize very easy.
