Electric energy into machinery to promote the fan rotation
The rotor of the DC cooling fan includes the DC cooling fan blades, which is the source of the air flow, the fan shaft, which is used to support the balance blade rotation, the rotor ring, the permanent magnet, the key to switch the speed of the magnetic level, Fixed magnetic ring. In addition, it also includes the support of the spring, through which the components are fixed to the tuberculosis to rotate the entire part, the motor part, the production rotation direction, and the dynamic size of the rotation speed key. Its speed performance, control is simple. DC Fan Portable Dc Fan ,Dc Usb Led Fan, 12 Volt Dc Fan, Dc Ceiling Fan Ningbo APG Machine(appliance)Co.,Ltd , http://www.apgelectrical.com
LED lamp price <br> <br> frequency shrunk recently, Fujian Bandai good Photoelectric Lighting Co., Ltd. Chairman Wu Ching-label announced that its products across the board price cut of more than 25%. This move instantly "exploded the pot" in the industry, and was quickly interpreted as the beginning of the "price reduction tide" in the domestic LED residential lamp market.
Wu Qingbiao once said in an interview with the media that "the purpose of price cuts is to attract large orders from international giants, achieve mass production, seek further price cuts, and quickly open up the domestic market."
After Bandai’s price cuts, the price war in the domestic LED residential lamp market has intensified. “The number of LED lights in the civilian sector on the market has rapidly increased from less than 10 years ago to more than 40, and the price has been 'shrinking'.†Mr. Liu, a well-known LED manufacturer in Xiamen, told reporters, for example, a 7W Light bulbs can be sold for 40-50 yuan last year, but this year they can only sell for 20 yuan. Some small factories' products can be sold for 12 yuan - 13 yuan.
A marketing department of Tongshida also told reporters that nowadays, many domestic manufacturers sell LED lights, which are usually lowered once a quarter, and the price adjustment range is 3%-5%.
Behind the “price war†in the civilian market , the huge market potential of LED residential lamps is being highlighted.
The reporter learned that since the beginning of this year, many local LED SMEs' export orders have shown a downward trend, and foreign customers have also deliberately lowered prices, resulting in a gradual decline in the industry's profit margin. At the same time, as the technical standards of the LED industry have increased, the price of upstream chips has continued to decline. The industry believes that with the rapid decline in the price difference between LED lights and traditional lighting, the domestic LED civilian market will become a new battleground for corporate Nuggets.
“In the past, the domestic LED civilian market share was less than 5%, but now it is increasing at a rate of 200% per year.†Topstar officials told reporters that in order to seize the market, the company has developed 40 new models. The products, all of which are civilian lamps, will be put on the market in the near future.
At the same time, the reporter visited and learned that at present, there are nearly 100 kinds of LED lamp brands that can be bought in the Xiamen market, about one-third of which are civilian products, which is nearly four times higher than two years ago. .
Companies complain the public applauded <br> <br> Reporter survey found that "price war" only superficial excitement, for many companies, it is increasingly sad day. LED manufacturer Mr. Liu said, "The profit may be even lower in the future, and some companies may be eliminated."
However, the company is complaining, but the public is applauded. “Before all the LED lights were being promoted, but the price has been very high.†Mr. Li told reporters that nowadays, as the price of LED lights continues to drop, ordinary consumers can afford them, which is really a good thing.
However, the reporter visited and found that although there are many varieties of civilian LED lamps currently on the market, the prices are not uniform. "Objectively speaking, although the domestic sales price of LED lamps has been reduced to varying degrees, it has not yet reached the same low price as ordinary lighting products." A person from the Xiamen Optoelectronics Industry Association told reporters that, in addition, due to the current domestic LED The national standard of the product has not yet been formulated, so the brand is messy. When the public buys, they should not choose the low-quality products because they are cheap, resulting in unnecessary losses.

A "price war" set off by an ordinary LED civilian light bulb
An ordinary LED civilian light bulb, from last year to this year, the price has shrunk more than doubled.
