LED lights first gets specific policy support

The state council has through the "1025" new planning, decided to speed up the energy saving products production device upgraded, call for saving, green, low carbon consumption idea, and eventually arranging financial subsidies 2.2 billion yuan, the promotion of energy-saving lamps and induction light development. Analyzed that the policy support determined the energy saving for the future of the industry support trend, LED lamp is the world's third generation lighting products, will with the leading technology and energy saving low carbon efficacy, occupies a unique advantage.

Industrial securities analysts LiuLiang, told reporters "countries each year there will be ten of energy-saving lamps few subsidies, this year's digital expanded to 2.2 billion, covering expanded to the third generation lighting products. Although the distribution proportion is not clear, but this is the first time the LED lights for specific policy support, meaning that is very clear." It is reported, the LED downlight appliance by using solid discharge mode, not only the ordinary than gas discharge energy saving lighting lamps and lanterns more province electricity, and do not contain mercury, more safety. "However, due to the high cost of LED lighting lamps, Japan market penetration rate, probably about half the highest, European and American countries is in rapid development, and domestic popularization stage because the price and consciousness, in the development stage restrictions.

The financial subsidies, advocating a clear energy saving low carbon trend, the future will certainly get more support and attention," LiuLiang added.
Reports indicate that all are being held a hearing ladder electricity price, although details of the implementation and a lot of debate, but doubt electricity price rise. LiuLiang explanation, "this energy saving lighting is certainly positive news. At present although household lighting electricity use limited, but the whole lighting also include commercial electricity and industrial lighting electricity, according to the data, the foreign a at the ratio of more than 20%, is also very big demand." Once the demand start, the development of the industry will get a driving force, plus policy support and financial aid, the future will certainly rapid development.

XiangCai securities analysts ZhuLiXu said, "involved in the business of the company is more, halogen lamp the fundamentals of related companies were different, and has the core technology companies benefit from higher level, more easier access to funds and policy tilt. Suggestions investors can long-term attention, understand the fundamentals ZhongChangXian after operation."

LED the utility load dimmers still very rare

LED need a and incandescent lamp or 7mm full spiral energy saving lamp entirely different types of drive. Incandescent lamp for a stable performance since the characteristics of pure resistance loading, LED is in need of a current source. Produce of the flux LED proportional to approximate the current flows through the device. The positive voltage with current LED increased, but with increasing temperature and reduce. In this respect, LED performance as a diode. However, in the course of work LED the positive voltage (VF) is very big. This voltage and electronic into when the photon energy produced (eV) related, this energy directly related to the color of the light again. In addition, the different production batch of VF value between can vary greatly.

Standard industry and household dimmers designed to incandescent lamp, some more advanced model can and connected to the transformer halogen lamp used together. At present specifically for the utility load LED dimmers still very rare.
Buy and install a new special dimmers of costs can be easily more than light itself, so a move light with existing infrastructure work together china LED Street Light system (such as based on NXP SSL2101 building system), will open the large market potential and space of the gate.
Because of the existing dimmers is designed to incandescent lamp (approximate resistance loading, mostly in the power 20 W and 50 W between), so we need some extra circuit to allow they are used in LED lighting systems. On the market at present is not incandescent lamp dimmers standards, so that now on the market has a lot of different performance parameters and the utility the dimmers.
The existing LED street lamp and the family common china halogen bulb solutions basically is divided into two parts, one is 220 V utility the switch to 24 V or 48 V AC-DC power adapter and, in part, LED to provide the driving current LED boost controller. This division solutions for not only more components, and takes considerable space. In order to solve these difficulties, NXP developed integrated single chip solutions SSL2101. It is also the first integrated adjustable light utility LED drive.
