Not long ago, according to Xinhuanet, China’s energy conservation and emission reduction efforts were unprecedented in 2007. “Energy saving and emission reduction†has become one of the eight most popular hot words used in China's economic life in 2007.
Although people are familiar with energy conservation. But when it comes to lighting energy conservation, energy-saving lamps seem to be the only words of people. In the face of ordinary incandescent lamps, energy-saving lamps are indeed responsible for the energy-saving task. But we should see that lighting products are developing, and more and more energy-saving light sources are being used. Before we move forward in the general direction of energy conservation, we should first understand the meaning of energy conservation.
Than one ratio - energy saving kung fu test depth
How to carry out “speaking and solving words†for lighting energy saving? Light efficiency, luminous flux maintenance rate and average life expectancy are three important parameters. At the same power, the higher the light efficiency of the light source, the higher the lumen maintenance rate and the longer the life, the more energy efficient.
Who is an energy-saving light source in the field of industrial lighting in China? At present, mercury lamps, high-power energy-saving lamps and metal halide lamps are three kinds of light sources commonly used in industrial lighting.
Now, we use the above indicators and consider the investment cost factors in the actual application, and these three will be “energy-saving competitionâ€.
Light efficiency / average life comparison mercury lamp self ballast mercury lamp energy saving lamp (CFL) metal halide lighting effect (lumen / watt) 45 22 55-80 75-106 average life (hours) 15000 10000 5000-10000 8000-20000
As can be seen from the above table, mercury lamp is the most widely used light source for industrial lighting, but it consumes the most electricity; the high-power energy-saving lamp takes the second place; the metal halide lamp consumes the lowest power. Although the initial investment in metal halide lamps is slightly more expensive and mercury lamps are the cheapest, metal halide lamps and high-power energy-saving lamps have advantages over mercury lamps in terms of total operating costs (initial investment, maintenance, and total power consumption). Taking one year and lighting for 12 hours a day, for example, in the case of achieving the same lighting effect, the metal halide lamp saves 45% more than the mercury lamp, and the energy-saving lamp saves 22% compared with the mercury lamp. Therefore, the metal halide lamp and the high-power energy-saving lamp are far higher than the mercury lamp in terms of return on investment.
Before the energy-saving indicators, mercury lamps apparently “unmatched†high-power energy-saving lamps and metal halide lamps.
Energy-saving light sources show their talents
Metal halide lamps and high-power energy-saving lamps are energy-saving solutions for replacing mercury lamps, but their advantages and applications vary. The advantage of metal halide lamps is that they have the largest amount of energy savings, and both high and low ceilings are suitable. High-power energy-saving lamps have certain energy-saving effects. The advantage is that the initial investment is small and the replacement is convenient. In particular, the self-ballasted mercury lamps below 250W are replaced, but only suitable for low-rise buildings. In a high-ceiling environment, high-power energy-saving lamps are “powerless†in terms of energy conservation. Here, the energy-saving stage is handed over to the metal halide lamp.
According to Mr. Xu Zhiwei, senior engineer of Shanghai Baosteel Engineering Technology Co., Ltd., since the mid-1990s, Baosteel has replaced the high-ceilinged factory with metal halide lamps in the new project. The metal halide lamp not only has a long service life, slow light decay, but also high illumination and good color rendering, and has become the "toon" of the industrial lighting high-bay factory.
What is the real lighting energy saving? The chairman of the China Lighting Society, President Wang Jinxi, concluded that energy conservation is not only a technical issue, but also a consciousness issue. In order to make different energy-saving light sources do their best for different lighting environments, we can guide the future road of energy saving in a farther direction.

It has long-strip shape, and it is mainly used for decorative lighting of building or outline of huge buildings. With a large number of models, it has many advantages such as bright and luminous efficiency, energy saving, rich in color, bright and beautiful patterns, high light efficiency, long working life as long as 50,000 hours, resistant to high temperature and low temperature, non-pollution, etc.. The Wall Washer Light includes seven-color wall washer light, full-color wall washer light and multi-color wall washer light. Its power capability determines the distance of its projection, and it is mainly divided into different levels of 18W, 24W, 36W and 48W, etc.. The power can be changed flexibly according to the requirements. It can be controlled by microchip to achieve many dynamic effects such as gradual change, hopping change, color flashing, random flashing and alternating gradual change.It is widely used in commercial properties, hotels, exterior walls of buildings, squares, staircase lightposts, parks, roads, garden trees, ancient buildings and so on. In recent years, LED Wall Washer Light is commonly used in lighting project.
