Energy-saving analysis of LED fluorescent light compared with traditional fluorescent light---The development trend of worldwide lighting
隨著歐美國際陸續(xù)頒布節(jié)能、環(huán)保的各種法令,人類用白熾燈照明的歷史將逐漸成為過去,我國目前雖然尚未頒布此類法令,但節(jié)能減排已經(jīng)作為一項(xiàng)基本國策,以至中國國務(wù)院辦公廳近日頒布實(shí)施單位GDP能耗考核體系任務(wù),把節(jié)能和環(huán)保與官員的政績掛鉤,從明年(2008)起,各地官員將開展向中央上交節(jié)能答卷,若達(dá)不到節(jié)能標(biāo)準(zhǔn)的各地黨政一把手將實(shí)行一票否決制。為大力提倡使用新能源,綠色能源作為新光源的照明工具，近期國務(wù)院已設(shè)立半導(dǎo)體照明推進(jìn)辦公室，在半導(dǎo)體照明方面已清晰地看到我們國家在推廣使用方面的決心。
The history of man used incandescent lamp will become in the past gradually with a variety of laws promulgating of energy-saving and environmental protection in the European and US successively. Although laws such like that haven't been promulgated currently, energy conservation and pollution reduction have been given as a basic national policy in China. And the General Office of the State Council of China recently issued and implemented the unit GDP energy consumption assessment system for the task, which energy-saving and environmental protection will be linked to performance of officials. From 2008 on, the officials of local government will report to the central government about energy-saving task. The first in command of local party and government will be denied by one-vote-down system if they cannot reach the target of every-saving. In order to powerfully advocate and promote the use of new energy---green energy as the lighting tool of new light source, the council of state recently established promoting office of semiconductor lighting. We can see the determination to promote the use of semiconductor lighting clearly in our country.
那么半導(dǎo)體照明與傳統(tǒng)照明有哪些優(yōu)勢(shì)和優(yōu)點(diǎn)呢？為什么值得國家下大決心推廣呢？下面就此，簡單的作一些比較和論述：
Then what is the advantages and strengths of semiconductor lighting ? Why is it worthy of great determination to promote by government ? Some comparisons and concerns are as follows in brief.
一、白熾燈、LED日光燈（含一般熒光節(jié)能燈）、LED半導(dǎo)體照明燈的發(fā)光原理及其性能特征：
The luminescent configuration and theory and function features of incandescent lamp，LED fluorescent light(including common fluorescent light) and LED semiconductor light.
1、白熾燈是根據(jù)電流的熱效應(yīng)制成的發(fā)光器件，它是將燈絲（一般為鎢絲）電流通電加熱到白熾狀態(tài)，利用熱輻射發(fā)射出可見光的電光源，至500℃開始發(fā)出可見光，隨著溫度的增加，從紅-橙黃-白逐漸變化，燈絲的溫度在白光時(shí)高達(dá)2000-3000℃，40W的燈泡外表溫度約60℃，100W的可達(dá)200℃，甚至周圍物體會(huì)被烤焦，壽命低，約為1000小時(shí)，光效低，約為10-20 lm/W。
The incandescent lamp is luminescent device made fro m heat effect of the current. The filament (usually tungsten) current is electrically heated to reach incandescent status and emits electric light sources of visible light at 500 degrees Celsius through thermal radiation. As the temperature increases and red-orange yellow-white color changes, the temperature of the filament reaches 2000-3000℃when during white color, the surface temperature of the 40W bulb reaches 60℃, the 100W reaches 200℃, even some will scorch surrounded bodies. Shorter life, around 1000hrs; Lower light efficiency, only 10-20 LM/W.
2、日光燈（熒光燈）主要是通過鎮(zhèn)流器或電子鎮(zhèn)流器形成700V左右的中高壓接于兩端燈絲，燈絲開始發(fā)射電子，電子碰撞氬原子產(chǎn)生非彈性碰撞，氬原子碰撞后獲得了能量又撞擊汞原子，汞原子在吸收能量后躍遷產(chǎn)生電離發(fā)射253nm的紫外線，紫外線激發(fā)熒光粉發(fā)光，熒光燈工作時(shí)燈絲的溫度在1100℃左右，壽命不高，約為5000小時(shí)，光效率為50 lm/W，現(xiàn)在市場流行的節(jié)能燈實(shí)際為高頻的熒光燈，工作原理并無大的區(qū)別，壽命約為6000小時(shí)，光效率約為80 lm/W。
The fluorescent lightis connected with each end of filament by 700V medium-high voltage of electronic ballast. The filaments emit electrons, collisions of electrons with Argon atoms make inelastic collision, Argon atoms collide Hg atoms again after gain collision energy. Hg atoms transitions produce ionizing and emit 253nm ultraviolet radiation after absorbing energy so that the ultraviolet radiation excites fluorescent phosphor and luminesces. The temperature of the filament can reach 1100℃while fluorescent light works. Shorter life, about 5000hrs; light efficiency is 50 LM/W. Currently The popular energy-saving light in the market is actually high-frequency fluorescent light. No bigger difference for the two. The work life of the latter is about 6000hrs and the light efficiency is about 80 LM/W.
3、LED日光燈主要是由多個(gè)LED點(diǎn)光源的組合，通過導(dǎo)光板有效分光發(fā)光，LED發(fā)光為半導(dǎo)體芯片直接發(fā)光方式，所以產(chǎn)生的熱量很少，而且單色性好，光譜窄，無需過濾，發(fā)出的光即為可見光，白熾燈其色溫約在2500K-3000K，偏暖（即偏黃），日光（熒光）燈的色溫約在6000K-6800K（白色），LED燈可根據(jù)工作場地及工作性質(zhì)需要設(shè)置色溫，照明的色溫實(shí)際比日光燈的6000K更高些，即更偏冷些，人的視覺感會(huì)更舒服，一般根據(jù)工作場合可在5000K-10000K色溫區(qū)選擇，一旦完成設(shè)置，工作十分穩(wěn)定，LED日光燈的壽命可高達(dá)3萬小時(shí)，光效率可達(dá)90Lm/W以上。
The fluorescent light is composed of multiple LED point lights which effectively split light and emit light through light panel. LED luminescence belongs to direct light mode of semiconductor chips which includes less heat, better monochromaticity, narrow spectrum. It doesn’t need to filter and emits the visible light. The color temperature of incandescent lamp is about 2500K-3000K, warm and yellow; the color temperature of common fluorescent lamp is about 6000K-8000K, white. The color of temperature of LED fluorescent lamp might be configured according to work place and work category and it is higher and colder than 6000K of common fluorescent lamp. Also, it’s comfortable for man’s visual perception. Generally it’s can be chosen between 5000K and 10000K according to workplace. It will be working sufficiently stably once accomplish configuration. The work life of LED fluorescent lamp can reach 30000hrs and the light efficiency can reach 90LM/W.
二：LED燈與其他照明燈的性能對(duì)照表：略
三:LED日光燈比傳統(tǒng)日光燈的節(jié)能分析：以照度基本相同的12WLED日光燈燈和40W的熒光燈作為對(duì)比，按照地鐵站的使用情況分析如下：
The energy-saving analysis of LED fluorescent lamp and traditional fluorescent lamp: the following is the comparisons based on same illumination 12W LED fluorescent and 40W common fluorescent according to the use condition of subway station.
1、基本單價(jià)：
Basic Unit Price
※一只優(yōu)質(zhì)的12W半導(dǎo)體燈售價(jià)約為190元，（價(jià)格會(huì)不斷的下降）。
A quality 12W semiconductor lamp sells at 190RMB (the price will be lower constantly)
※一只較好的40W日光燈（含燈管）的價(jià)格約為60元（價(jià)格已穩(wěn)定）；
A better 40W fluorescent lamp (includes lamp tube) sells at 60RMB (stable pricing)
2、每天消耗電能：
Power consumption of everyday
地鐵站的照明時(shí)間每天按照24小時(shí)工作計(jì)算，標(biāo)稱40W日光燈的耗電實(shí)際約為45W，
The power consumption of the standard 40W fluorescent is about 45W. The lighting time of subway station can be calculated 24hrs everyday and we get :
※半導(dǎo)體燈每天耗能=12瓦×24小時(shí)=0.288千瓦時(shí)
Power consumption of semiconductor lamp of everyday = 12W * 24hurs = 0.288KWh
※ 日光燈每天耗能=45瓦×24小時(shí)=1..08千瓦時(shí)
Power consumption of fluorescent lamp of everyday = 45W * 24hrs = 1.08KWh
3、每天節(jié)省電能的費(fèi)用
Saving energy cost of everyday
※按照深圳市每度照明用電平均1元計(jì)算
According to Shenzhen lighting power standard: 1RMB for 1KWh
※LED日光燈每天節(jié)省費(fèi)用=1.08-0.288=0.792（元）
Saving cost of LED fluorescent of everyday = 1.08RMB – 0.288RMB = 0.792RMB
4、投入相同價(jià)格成本的平衡點(diǎn)時(shí)間（未考慮人工維護(hù)成本）
The balanced time launching same cost of price (ignore artificial maintenance cost)
※(半導(dǎo)體燈購燈成本-日光燈購燈成本) /每天節(jié)省的費(fèi)用成本,即(190-60)/0.792=165（天）,即不到一年
(The purchasing cost of semiconductor lamp – the purchasing cost of common fluorescent lamp) / The total saving cost of everyday = (190 – 60) RMB / 0.792 RMB / day = 165 days (less than a year)
5、按照使用5年時(shí)間計(jì)算的LED日光燈燈比傳統(tǒng)的日光燈節(jié)省的成本費(fèi)用（日光燈按每一年更換一只燈管計(jì)算,每只燈管按12元）
The saving cost of LED fluorescent lamp compared with traditional fluorescent lamp according to the use of 5 years time (the damage rate of traditional fluorescent lamp can be calculated that one lamp tube must be changed within one year and one lamp tube costs 12RMB)
※日光燈的總投資費(fèi)用=購燈成本+4只燈管的成本費(fèi)用+5年的電費(fèi)=60元+(12×4)元+0.045千瓦×1元×24小時(shí)×365天×5年=2079元
The total investment of traditional fluorescent lamp = the purchasing lamp cost + the cost of 4 lamp tubes + energy charge of 5 years = 60RMB + (12RMB * 4each) + 0.045KWh * 1RMB * 24hrs * 365days * 5 years = 2079 RMB
※半導(dǎo)體燈的總投資費(fèi)用=購燈成本+5年的電費(fèi)=190元+0.012千瓦×1元×24小時(shí)×365天×5年=715.6（元）
The total investment of LED semiconductor lamp = 190RMB + 0.012KWh * 1RMB *24hrs * 365days * 5years = 715.6RMB
即第5年時(shí),一12W的半導(dǎo)體燈比一40W的日光燈總成本費(fèi)用節(jié)省了2079-715.6=1363.4（元）
That’s to say, the saving cost of one 12W semiconductor lamp compared with one 40W traditional fluorescent lamp is 2079RMB – 715.6RMB = 1363.4RMB when the fifth year arrives.
四:按照10年和5年計(jì)算
The calculation based on 5years and 10years
※日光燈的總投資費(fèi)用=60元+12×9元+0.045千瓦×1元×24小時(shí)×365天×10年=4110（元）
The total investment of fluorescent lamp = 60RMB + 12RMB * (4+5) each + 0.045KWh * 1RMB * 24hrs * 365days * 10years = 4110RMB
※半導(dǎo)體燈的總投資費(fèi)用=190元+0.012千瓦×1元×24小時(shí)×365天×10年=1241.2（元）
The total investment of LED semiconductor lamp = 190RMB + 0.012KWh * 1RMB * 24hrs * 365days * 10 years = 1241.2RMB
節(jié)省成本費(fèi)用4110-1241.2=2868.8（元）
The total saving cost = 4110RMB – 1241.2RMB = 2868.8RMB
※按1000只燈計(jì)算5年和10年分別可節(jié)省成本費(fèi)用
The calculation based on 1000each within 5 years and 10 years
5年節(jié)省成本費(fèi)用1363400元
The total saving cost of 5 years = 1363400RMB
10年節(jié)省成本費(fèi)用2868800元.
The total saving cost of 10years = 2868800RMB
