Japan earthquake, eastern peak periods, the situation is very serious cuts, Japan is considering a new nuclear policy, recently, the Japanese Environment Ministry State Secretary for the Environment said that the next year in May, Japan will stop all new nuclear power plant approvals.
On the one hand, Japan is more a lack of resources and energy, so Japan will encourage the development of solar, hydro and other clean energy sources, efforts to achieve energy diversity. On the other hand, Japan will increase the development and application of energy-saving technologies, the Secretary also said that the government is now encouraging people to use energy-saving LED light bulbs, installing energy-efficient heating system if the family will receive government financial support.
Today, most lamps and light sources using standard A19 light bulb size, and now these lamps have aLEDVersion, but expensive. For example, the equivalent of 40W or 60W bulbsBrightnessOf LED Bulbs, its retail price was $ 20 and $ 40. SomeLED lights dimmable, and some is not adjustable; some only a few specific LED lights dimming file. Usually three or four hours in the conditions of use, these LED light bulbs are claimed to have 25,000 to 50,000 hours life expectancy. If used properly and sparingly, these LED lighting bulbs are also likely to live longer than the user. However,LED bulbs Why so expensive? Are they really worth it?
In the component analysis to find scientific answers to the company MuAnalysis process, we were dismantling the five A19 LED bulb: where 1 is the Philips Products (12.5W/800Lumen), Equivalent to 60W regular bulb; the other four were from Feit, GE, Pharox and Sylvania products, equivalent to 40W regular bulb. By dismantling these five bulbs, we found lot of problems.
LED bulbs in each package with a special design, and CFL bulbs with tungsten coated heat-shrinkable packaging, these LED bulb cool packaging to increase the overall cost. Obviously, these bulbs give way yet to figure for the general merchandise; them expensive, and this trend is expected to continue.
However, in the current rapid decline in prices of electronic products of the environment, long life is no longer the sole focus of attention. So, why a light bulb a low-cost product than we have digital cameras expensive?
For such a simple product like a light bulb, the appearance is definitely a selling point. We study the dismantling of every appearance of LED bulbs are unconventional. For example, GE light bulbs with ceramic lining the neck and wings, with a glass stem and base, which more than plastic and metal products and high cost.
All bulb lights are equipped with a small neck printed circuit board, a large volume of electrolytic capacitors and transformers?? Is essential to the protagonist of the board. LED spotlight reliability factor has been greatly improved; However, in the heat of the working conditions, the electrolytic capacitor can have a long life?
Dimmable bulb Infineon or STMicroelectronics Of Power Transistor. In these lamps, we did not find silicon carbide technology.
Each lamp usesLED DriverICAre different. Pharox using four IC, 40 resistors and 16 capacitors, plus a transformer and a number of diodes. All this is equivalent to 40W for a dimming of the LED light bulb, of course, but in some cases, when you are old may not be compatible with dimmers only when the need to buy a new dimmer.
Philips uses a tiny phosphor encapsulation material depends on the wavelength conversion bulb. Lamps in more than a lutetium oxide is used as a fluorescent medium. Over the past few years, we pay attention to many kinds of LED bulbs, but has not seen with the lutetium element. Which uses such as barium and cerium-doped YAG(Yttrium aluminum garnet) phosphor and other more traditional, there is also other rare earth elements, such as europium and strontium.
Surprisingly, these LED Ceiling Light use a blue GaN LED, did not use the RGB LED. In Pharox products, and with a red LED Lens, But the lamp is on, the red LED does not work. Clearly, these red LED Ceiling Light is not used for color balance. Perhaps, only when the light bulb to be bad when it turns red bulb; bulbs or wiring used to indicate an error.
On September 14, 2011, Lighting Science Group made announcement to launch Glimpse™ LED spot light. this new spot light maintained all unique luminous output and high property that LED products owned and awarded better creative heat dissipation design to reduce the needing usage amount of raw material.

Recently, Shenzhen Fangda decoration project Co.,Ltd., wholly owned subsidiary of Fangda group, it was bidded and signed several large projects with total contract value up to 114 million yuan, those projects, such as, xindi center at Hefei, Anhui province, large and advanced curtain wall project of Diwang plaza at Jingde town, Jiangxi province, shenyang outdoor full color LED screen project and city plaza LED enlighting project.
In the upcoming Mid-Autumn Lantern Festival in Guangzhou on will be the first large LED light bulbs, this lantern will feature 20 group has a "sound, light, action" effect of light and medium-sized groups.
Green Lantern Festival is trying to convey this idea. In the previous carnivals, the incandescent lamp used more, very power. The performance of this group in the form of light, a large number of high-efficiency, energy-efficient LED lights, the total accounted for 80% of the total lighting.
Light tower in Guangzhou with the same group with the LED light-emitting materials, while changes in a multi-storey tower in different colors, highlighting the dynamic lines of the tower in Guangzhou, Guangzhou, to create a similar tower lighting effects.
According to the lighting designer introduced, the biggest highlight of this Mid-Autumn Lantern Festival Park is located in the cultural center of Central Square, the "mini-tower in Guangzhou", Guangzhou, this mini-tower height of 6.5 meters, this light will light up the group with the real tower in Guangzhou 650 m narrow times the height of the template to complete. LED light over one thousand by the material composition can change as real as the tower in Guangzhou color.
