DOE releases LED energy saving assessment report for market segments

LED light-emitting diode, also known as solid-state lighting (SSL), provides a new and revolutionary source for electrical lighting market, this source can save energy, and improve its quality, performance and service. Today, LED is able to provide high quality products and cost-effective performance, therefore, LED is trying to compete with traditional light sources through different types of applications.

This report describes the results of 12 kinds of LED for different market segments, namely LED is started from the traditional source market competition or for war, such as incandescent lamps, halogen lamps, high intensity discharge lamp (HID) as well as some type of fluorescent light. The report based on the current LED market penetration level, to assess the level of energy saving in 2010 LED lighting. In addition, if all of these different market lights are replaced by advanced LED lighting, the report will also be on the LED outdoor lighting energy saving technology potential assessment. People realize that these 12 market segments were identified on LED does not represent the progress of all applications made in the market, but these are the selected market can be used to reflect the current LED growth trends and growth potential. It is generally believed that some people use the term "niche" to describe the small or special market range, but the purpose of the report, "niche" not only refers to a variety of market segments, but regardless of its size, including the entire lighting market.

First, the 3 major markets for energy efficiency assessment

The market analysis of the report is divided into three parts: general lighting, outdoor lighting, consumer electronics display lighting.

In the application of these 12 segments of the market, LED products are being used and replaced by traditional lighting technology.

For general lighting, the current technology has been replaced by the LED, so in 2010 LED annual savings of 380 billion kwh of electricity. In terms of general lighting, LED has a longer service life (greater than 50000 hours), directionality, small size, ease of control and dimming, compared with the current technology. If these four kinds of ordinary lighting applications completely converted into LED, then save up to 133 trillion kwh per year.

LED is very suitable for outdoor lighting applications, in addition to its limited light pollution and light invasion, low temperature resistance, high resistance and high quality light source characteristics, but also has a significant energy saving potential. In these outdoor lighting applications, in 2010, LED total power savings of 2 trillion and 200 billion kwh, if all outdoor lighting is replaced by LED, it is estimated that the annual savings of electricity at 131 trillion kwh. Finally, it is worth mentioning that, because LED can provide better contrast light and improve the color gamut, has compact structure design, reliable mechanical design, long service life, fast response control and improve the energy saving, therefore, LED has been widely used in consumer electronic display field.

The results of the analysis report shows that in 2010, in consumer electronics applications, LED power savings of 1 trillion and 300 billion kwh. However, due to the existence of the high permeability and high efficiency of LED backlight technology, consumer electronics applications have the lowest energy saving potential. If all of the consumer electronics applications are replaced by LED backlight display, then, LED annual savings of up to 30 trillion and 700 billion kwh of electricity can be achieved.

Two, 12 market power saving effect and electricity saving potential analysis

In the report, from the following 12 segments of the field of electricity saving total analysis chart, figure ES.1 outlines the market segments of the field of electricity saving and power saving potential of the maximum value. At the same time, the power consumption of the family is concerned, the graph also makes a generalization of the equivalence of energy conservation. 2010, in the 12 segments of the market analysis in this report, the current market penetration of LED has achieved an annual total electricity savings of 3 trillion and 900 billion kwh.

Save power ES.1 chart was selected in 2010 the market segments

As shown in figure ES.1, in 2010, the main cause of power saving is attributed to LED applications, accounting for market dominance is the outdoor parking lighting, the market penetration is expected to reach 4.3% LED.

The chart shows that in 2010, about 40% of the energy savings from LED applications. Following the parking lot lighting, in 2010, the second major energy savings in the market is the application of regional and flood lighting, the total amount of electricity savings has reached 20%, and the market penetration of LED is about $0.72%. For desktop monitors, notebook computer and TV with LED backlight, LED MR16 and lamp, has significant energy saving effect, and accounted for 45% of the total energy savings in 2010. In other lighting areas, such as 2 feet x 2 feet of light bulbs and A lights, LED penetration rate is not high, less than the total energy saving of 2010.

Figure ES.2 summarizes the 2010 two market segments in the field of power saving potential application field, the report of the 3 group analysis report that in 2010 the energy saving potential and the total potential of the 12 segments of the market application field of power saving. The analysis shows that the total annual energy saving potential of up to 263 trillion kwh, if converted into LED, the total annual energy saving potential of up to 250 trillion BTU. This energy saving potential is equivalent to more than 21 million U.S. households consumed electricity.
