Luminous efficiency and cost effective continuous improvement LED lighting application prospects

In the LED market, LED lighting ratio is not high, but the growth of each application field is the fastest LED plate, special application of LED lighting market in the past mainly used in building wall lights, decorative lights and bicycle brake lights, but with the improvement of LED luminescence efficiency and costs continue to drop, in recent years has been advanced the state used in indoor lighting and street lamp field, in the future to further enhance the cost-effective, is expected in the market has been more than occupies an important position in the lighting market is $100 billion. High brightness LED market will be developed to LED display, backlight and lighting as the focus of the LED market can be divided into high brightness LED and general LED market, among them, the growth of demand comes from the application of high brightness, high brightness LED therefore accounted for the overall LED market share has been close to 8. The application of high brightness LED proportion, the past is the backlight to the screen of the mobile phone keys, but with the mobile phone market growth slowed down, and too many manufacturers to enter this market led to falling prices, expected future LED mobile phone market will gradually decline, the proportion of high brightness LED market will run from 2007 45% to 2011 25%. The new growth area is including LED display, TV/NB backlight and LED lighting LED, expected in 2011, the high brightness LED LED accounted for the overall market size proportion by 7% in 2007, increased to 13% in 2011 2011, when the LED lighting market size of up to more than $1 billion.

LED display backlight applications and LED lighting will be the most growth of high brightness LED project

Lighting market size LED for main breakthrough in power saving and long life global lighting market in 2008 for more than $110 billion, although the overall market has entered a mature stage, between the annual growth rate of only 3~5%, but because of life and urban construction essential supplies, so it can ensure the stability of the demand, if the LED can enter the the market, whether it is the lamp or lamps (Lamps) (Fixtures), opportunities in the future can not be ignored. Lighting market has a characteristic, that is in a lamp or household light bulb product life cycle, the main cost from electricity and maintenance costs (such as American workers repair the lights attendance cost up to $80~100 per hour), therefore, LED can overcome the problem as long as the price is high, the power consumption and characteristics with long life will be very favorable LED application in this market.

As the semiconductor industry according to the Moore's law for decades, the LED industry has its Moore law, Haitz law Roland Haitz is proposed, the law is analyzed since 1965, the output of every 10 years, LED lighting (output) increased 20 times, while the LED component unit cost is reduced by 90%. The current progress in the application of LED products in the lighting, or even slightly more than Haitz's prediction of the law, the industry is also expected to continue to grow in the medium and long term 2007~2016 will continue to grow in this law. As long as LED products in terms of efficiency and cost reduction can maintain this trend, LED industry will be able to continue to grow. If the U.S. Department of energy (DOE) and the 2010 Forecast of 2007 commercial LED light source and lighting technology standard, is expected in 2010, in the warm light (warm) and the total efficiency of lamps lighting efficiency white LED light source lighting, LED lamps are at least double level, so it can be expected in the future will be more LED lamps power (due to increased luminous efficiency) and lower cost, cold type LED light source and the lamp also has the same progress.

Of LED lighting market development in the long-term favorable factors, mainly in the energy and environmental protection trend LED substantial improvement in luminous efficiency and cost reduction, Haitz law progress continued in 2016. Lighting accounts for 8% of the total energy consumption of the United States, also accounted for 22% of U.S. electricity consumption (in other countries is relatively low, but the global average is about 20%), the United States alone, every year the light is required for lighting energy costs up to $45 billion or more, therefore, the main developed countries will encourage the application of energy saving technology.

LED indoor lighting, the price is still high at LED in indoor lighting universal problem, mainly is the price, compared to the general household lighting and LED traditional incandescent lamps or energy-saving light bulbs, LED lights, although the power consumption is low, but the price is still high, the service life of the LED lamp for 5 years to estimate, although during the bulbs the average service life of only 30 weeks, need to be replaced several times, but the overall cost (bulb + electricity) LED is higher (about 40% more), it depends on LED lighting costs continue to decrease, to benefit the general family conversion for the LED lamp bulbs. Incandescent bulbs due to environmental protection and power consumption will be eliminated, and therefore not enough to block the popularity of LED lights in home lighting.

LED is also used in retail and office / factory lighting in indoor lighting applications, LED is mainly used in retail display (Retail Display) related purposes, because the LED lamp can show cosmetics, jewelry and other items required for special lighting effects, and the use of LED light consumers do not feel loose, so nearly 3 years in a based on the average annual growth rate of more than 70%. In addition, convenience stores and other supermarket chains, due to the efficiency of LED at a low temperature is better, so the application of the refrigerator in the refrigerator light source, the effectiveness of LED can be seen. After all, only 4 hours a day for home lighting, street lights only turn on the lights every day for 10 hours, but in the supermarket freezer LED lights are likely to use for about 16 hours or even 24 hours, LED lamps will be able to play a more effective electricity saving.
