In recent years, the national power situation has been extremely severe, and energy conservation has become the consensus of the people throughout the country. Energy saving, ease the energy shortage; control environmental pollution, improve the quality of life overall lighting quality and environment of our city is imminent.
According to the State Council's work on building a conservation-oriented society, in order to alleviate the tremendous pressure on resources and the environment, and to achieve the energy conservation goals of the “Eleventh Five-Year Planâ€, the country is stepping up the energy-saving and environmental protection and economic reform projects. Currently, China is in the capital construction. During the period, the lighting quality and efficiency of industrial enterprises in most cities and regions were still very backward, and the potential for energy conservation was great, and they needed to be reformed. To this end, we report on the authenticity, importance, reliability and safety of power saving .
The status quo and analysis of lighting product development
(1) Light source:
The indoor lighting source is mainly fluorescent lamps, and the most widely used ones are:
1. T8 medium-diameter (26MM) straight tube type calcium halophosphate powder fluorescent lamp, with 36W as the standard, luminous flux of about 2600LM, average life expectancy of 7000 hours ; poor color rendering, fast light decay, 3000 hours of use, luminous flux attenuation of 30%.
2, T8 in the small diameter (26MM) straight tube fluorescent rare earth triphosphor: high luminous efficiency, subject to 36W, the luminous flux of about 3250LM, the average life of 12,000 hours; light is small, the use of 3000 hours, the luminous flux attenuation of only 10 %. It has good color rendering and is one of the most ideal light sources for energy saving, comfort, environmental protection and green lighting in the 21st century .
3, T5 straight tube type rare earth tri-color powder fluorescent lamp: high luminous efficiency, based on 28W, luminous flux is about 2600, average life expectancy 8000-10000 hours; light decay is small, 3000 hours, the luminous flux is only attenuated by 10%. It has good color rendering and is one of the most ideal light sources for energy saving, comfort, environmental protection and green lighting in the 21st century .
4, compact energy-saving lamps: electronic integrated energy-saving lamps; PLC lamps; PLL lamps.
(2) Ballast:
Inductive ballasts and electronic ballasts are used to illuminate fluorescent lamps.
1. Inductive ballast:
2, electronic ballast: high-performance electronic ballast (in line with national certification)
The following compares the power consumption of high-performance electronic ballasts with magnetic ballasts:
1, theoretical calculations:
Configure comparison objects:
Design: Inductive ballast T8, 36W, 1 / 1 set of lamps (national standard).
Electronic ballast T8, 1×36W, 1 / 1 set of lamps (3AAA).
Electronic ballast T5, 1 × 28W, 1 / 1 set of lamps (3AAA).
The inductor ballast is a power frequency 50HZ frequency lighting; the electronic ballast is a high frequency 20KHZ-50KHZ frequency lighting; the luminous efficiency of the lamp at high frequency is 10% higher than the power frequency, therefore, in the same brightness, the electronic town is used. The overall power saving of the device is more than 20% than that of the magnetic ballast . The indoor temperature rise of the magnetic ballast when working, and the electricity cost for cooling in the summer is not counted.
Comparison of power saving and operating costs:
Take industrial lighting as an example.
Example 1: T8 high-performance electronic ballast replaces T8 magnetic ballast If you need to set up T8 straight tube three-color fluorescent tube 36W 4000; 300 days per year; two shifts per day, work 21.5 hours; electricity fee 0.69 yuan / KW budget: Inductance ballast / only: its own power consumption 10W (national standard magnetic ballast), input total power 36W + 10W (national standard magnetic ballast), electronic ballast / only: its own power consumption 4W (3AAA electronic ballast ), input total power 32.00W + 4W (3AAA electronic ballast).
Ballast total power consumption (GB Ballast) :( 36 + 10) W / 1000 (KW) × 4000 ( only) × 300 (days) × 21.5 (hours) = 1,186,800 (degrees)
Total annual electricity consumption of electronic ballasts (3AAA): (32+4) W/1000 (KW) × 4000 (only) × 300 (days) × 21.5 (hours) = 928,800 (degrees)
Inductance ballast annual electricity fee (national standard inductance ballast): 0.69 yuan / KW × 1186800 = 8.189 million yuan Electronic ballast annual electricity fee: (3AAA): 0.69 yuan / KW × 928800 = 640,900 yuan
