Energy saving lighting: LED lighting era has been widely used in the field

LED illumination cost with the fluorescent lamp and the gap has been less than 5 times. Cost per watt is still 10 times higher than fluorescent lamps and other commonly used efficient light source, however, due to the characteristics of one-way LED light source, detailed product design and efficient drive circuit, the cost of illumination within 5 times. The illumination corresponds to the number of lumens in a particular area, which is a real concern for the user. The significance of the difference between the cost per watt and the cost of illumination is that the LED lamp will have a power saving effect of about 50% compared to that of a fluorescent lamp.

At present, cold white LED lamps in the field of non residential lighting has been economic. Consider the results of the calculation shows that the use of LED lights about 10000 hours to recover the cost, and product life has significantly exceeded this level. In order to consider the influence of the value of time, we are using a 20% discount rate, the current price is still found, 10 hours / day, 250 days / year of use has a positive economic value, which will include most of the non resident lighting applications.

There is still a huge decline in the cost of space, including the improvement of light efficiency, scale effect and return to reasonable industry. Chip prices have started at the end of 2011, LED light illumination cost will be lower than the current decline in 30-40%, we believe that the price will start after the warm white, or 4-6 hours / day, which includes most of the non resident lighting applications, and Home Furnishing lighting will start in 2012.

November LED lighting demonstration project will change the user's understanding of the characteristics of the LED products, early non-standard market competition and the use of experience to make it difficult for users to identify LED 20000 hours of long life. Demonstration application projects shortlisted companies mainly in Zhejiang sunshine (35.80, -0.46, -1.27%) and NVC.

Massive LED market, LED lighting involves chips, packaging, thermal conductive materials, light guide material, drive and other different areas. Global electricity consumption is about 20% of lighting, LED lighting will save more than half of the electricity consumption, which is the potential market capacity of LED.

Packaging and application of back-end in 2011 is more of a concern, because the chip supply chain including chip prices, and will trigger the lighting application expectation; LED lighting chip currently accounts for only about 15% of the price of the whole lamp, huge value-added products is in the period of manufacturing and channel links; and before the TV Backlight Market Chinese enterprises it is difficult to cut, the global lighting manufacturing capacity has been focused on the Chinese, China enterprises will become the dominant force. Focus on nationstar (42.00,1.39,3.42%), the Zhejiang sun, attention Fu Jing Technology (18.44,0.58,3.25%).

Chip focus on the field of micro Bo (23.32, -0.06, -0.26%), the Great Wall development (, -0.11, -0.86%). Despite the short-term LED lighting chip prices are in decline, but the lighting demand will eventually improve the pattern of supply and demand. Silan display chip is less affected by the decline in value, the green and blue chip belongs to the domestic first-class level; the development of the Great Wall with large-scale manufacturing management capabilities, in support of the wafer and billion light is expected to become the integration of upstream and downstream first-class manufacturers.
