LED lighting began to move from government projects to civilian markets

In 2010, the entire LED industry will usher in a tipping point, and it is not the government's “Ten Cities and Ten Thousands” project that ignited this fire, but pure commercial engineering such as large-size LCD TV backlights, indoor lighting and large display screens. According to isuppli, global 40-inch and larger LED-backlit LCD TV shipments will increase more than six times in 2010 from 2009, from 2.5 million units in 2009 to 18.8 million units. In 2010, global LCD TV shipments were approximately 180 million units, and LED-backlit LCD TV penetration was approximately 10%. However, penetration data is still changing, and the more optimistic forecast is to reach 20%. In the field of LED indoor lighting, in fact, the momentum of rapid growth has begun to appear at the end of 2009, and the export orders of mainland LED companies are in short supply.

 

    “The government attaches great importance to the LED industry. It is at the peak of the development of Shenzhen. It is also the peak period in the country. However, if the company only relies on the government to replace the LED lights to support the entire industry, it will not be realized. What is the driving role of LED? The key is that LED enterprises should develop in depth.” Chen Yingchun, deputy mayor of Shenzhen, expressed his presence at the 4th LED Summit Forum held recently. He gave Shenzhen, the LED packaging company occupying half of the country's cities, pointing out a very correct direction.

    Liu Zhen, president of Quantum Optoelectronic Technology International Co., Ltd., an LED packaging manufacturer in Shenzhen, explained the popularity of LED indoor lighting as follows: “The advancement of TOP (reflective cover-filled SMD-LED) technology has promoted the application of LED lighting in indoor work areas. Due to the quantum efficiency in the low-power LED chip and the increase in quantum efficiency outside the TOPLED package (120 lm/W), the heat generation is greatly reduced. The TOPLED, which has various problems, can be widely applied, thereby driving the heat of the LED fluorescent lamp. pin."

    However, he also analyzed, "In fact, in terms of cost performance, LED fluorescent lamps and three primary color T5 fluorescent lamps are still in the face of the possibility of competition, and now the user's enthusiasm for LED lights may be more impulsive." So, in the LED indoor lighting Also expect more technological breakthroughs, in which the improvement of LED luminous efficiency will be the most direct influencing factor. “It is clear that as the luminous efficiency increases, the number of LED particles in the LED fluorescent lamp will drop significantly, which will directly bring about a cost reduction.”

    Liang Zhihua, deputy director of finance of Shenzhen Lanke Electronics Co., Ltd. also said that the company is a member of the National Semiconductor Lighting Technology Standards Working Group. He explained that because the current indoor lighting generally uses low-power LEDs below 0.5W, a 20W flat-panel lamp will have nearly 200 LED particles. If the LED luminous efficiency increases, the LED particles will decrease, and the cost will naturally fall. .

    Zhong Qun, director of China Semiconductor Lighting Engineering Technology R&D Center, also pointed out: "Technically, indoor lighting is easier to develop than outdoor lighting. LED indoor lighting products of many Chinese companies have been exported in large quantities. But because of the current energy saving than traditional light sources. There are not many LED chips, and the market needs to wait for a large-scale development."

    However, there is a field that has really set sail on a large scale, which is the LED backlight of large-size LCD TVs. "Because of the advancement of LED backlight components, the LCD TV billboard market has entered the harvest period in advance." Liu Zhen said.

    Samsung is the hero of the LED-backlit LCD TV in the world. Stimulated by Samsung's continuous increase in LED-backlit LCD TV production, the world's mainstream LCD manufacturers have all followed, and Chinese LCD TV manufacturers are also rapidly following. At present, mainstream LCD TV manufacturers in China have all launched LED-backlit LCD TVs. This wave of unexpected expectations has led to a serious shortage of LED chips. It is reported that Samsung has increased the shipment of LED-backlit LCD TVs in 2010 from 2.5 million units in 2009 to 10 million units, which makes it consume most of the production capacity of Taiwan's LED chip maker Jingyuan Optoelectronics. The supply of many Chinese LED package manufacturers has become quite tight. Because many LED packaging manufacturers in China use crystal chips.

    According to the optimistic estimate of the China Electronics Chamber of Commerce, the sales of domestic LED-backlit TVs will increase by 4 times in 2010 to 4 million units, and the penetration rate of LED-backlit LCD TVs in the Chinese market will exceed 15%. Zhong Qun pointed out that "China has little backwardness in the field of LED backlight technology, and the opportunity is very large, as long as China's TV manufacturers can give local LED backlight companies more opportunities." A mobile phone screen requires about 10 LED devices, but A 42-inch LCD TV requires 1000 LEDs. This huge market will bring unlimited business opportunities to China's LED backlight companies, and it is likely to create a group of leading LED packaging companies.

Plate non-damaged desulfator with Smart pulse,Simple and Safe,Save your money, time and worry.
Most of Electric vehicle use lead-acid battery bank(12V /6V /8V cells packed in Series)as the power source. The design lifespan of battery is 2~3 years, but actually the battery is usually failure after 6~12 months used which State-Of-Capacity gradually decline and even some scraped. Through analysis by cutting a large number of failure batteries, the battery water loss and sulfation is quite prominent. Such as the phenomenon of battery sulfation and dehydration can be effectively inhibited to prolong the service life greatly up to 2 times.
Battery Smart Pulse Charging Restorer is a new generation of high-tech products developed specifically for restoring Electric vehicle battery and UPS power system when it is charging every time, it utilizes the energy from the charger, generating electronic smart pulse with special frequency to be resonance with the thick lead sulfate crystals in battery charging process. Under the disturbance by the specific frequency pulse, the recrystallization of lead sulfate can be prevented effectively.
Battery Charger And Restorer 2-in-1 is a multiple-stage charger with smart pulse maintenance ability. This innovative, state-of-the-art battery restorer smartly knows how to restore battery in charging process, Unlike other common chargers on the market, you don't need to select the battery type. It works smartly on any type of 12/24/36/48/60/72-Volt lead-acid battery – VRLA, AGM and flooded. Proprietary algorithms combined with microprocessor & IC controlled technology measure the battery's voltage and current to automatically determine and deliver the precise pulse frequency and duty cycle based on the size and condition of the individual battery.
It is more than a common pulse charger and desulfator.  During the restorative battery charging cycle, VoltaTech's patented, optimized frequency pulsing and smartly changeable duty cycle constantly work to minimize and reduce battery sulfation and internal resistance.  By reducing the size and number of lead sulfate deposits on the battery plates- the No.1 cause of battery failures, increase capacity and release energy to keep battery in new conditions, your battery will charge deeper, maintain greater reserve capacity and last longer service lifespan– up to 2 times longer.
