The Car Body refers to the part of the vehicle used to carry people, and also refers to the whole vehicle. The body of some vehicles is both the driver's workplace and the place where passengers and goods are accommodated. The body includes windows, doors, cockpit, passenger compartment, engine compartment and luggage compartment. The shape of the body is several types, such as a box type, a fish type, a ship type, a streamline type and a wedge type, and the structural form is divided into a single compartment, a hatchback and a sedan. The body structure is the body language of the vehicle, and its design will directly affect the performance of the vehicle.
The body shell is the basis for the installation of all body car auto parts, usually referred to as the rigid bearing structure of the main bearing elements such as the longitudinals, beams and struts and the elements connected to them. Most of the bus body has an obvious skeleton, while the car body and truck cab have no obvious skeleton. The body shell usually also includes materials and coatings for sound insulation, heat insulation, vibration, corrosion, sealing, etc. laid thereon.

The competition in an industry was not fierce at the beginning, but with the rapid development of the industry, a large number of enterprises emerged. The disorderly competition and homogenization competition became one of the laws of the industry. Under this rule, customers often cannot clearly perceive the differences between the products of various enterprises, so the price becomes the dominant factor, thus forcing enterprises to use price as the main competitive means of differentiation.
The LED lighting industry began to emerge in the lighting industry from the ten cities and towns launched by the Ministry of Science and Technology in 2009, and expanded rapidly in the next few years. LED driver power supply, which is one of the core links in the LED lighting supply chain, is no exception. Especially in recent years, the law of homogenization and price war competition seems to be getting worse.
Entering 2014, the domestic and international LED lighting sector policies are positive. The US government's comprehensive ban on the production and import of incandescent lamps has officially entered into force, and the incandescent lamp phase-out plans in Canada, the European Union and other countries and regions have also begun to take effect in batches. Various policies have made LED companies see the dawn of hope. LED practitioners are also more convinced that the first year of LED lighting will be launched in 2014, and the next three to four years will be the golden development period of the LED industry.
In addition to the global favorable policies, the cost reduction driving terminal price drop is also the main factor that triggers the outbreak of the lighting market. Recently, the industry's call for LED lighting is getting higher and higher. Simple, cheap and easy to use are the key points emphasized by these supporters.
In 2014, the driving power supply should do this: ensure reliability and safety, pursue efficiency and constant current accuracy, try to suppress ripple and noise, and properly adjust the linearity. Dong Pei, chairman of Dongguan Feiwang Electronics Co., Ltd., said in pursuit At the same time, we must consider the price of the product, and ensure that the low price is the constant pursuit of the LED light source manufacturers.
Then how to measure this price/performance ratio? What is the low price? Is a 1 yuan 3*1WLED bulb built-in drive power, is 3.8 yuan high efficiency (90) 3 * 1W thyristor dimming power 3w drive power, or open circuit protection and overvoltage protection of 5 yuan full voltage high Power factor (0.97) non-isolated lamp drive?
Long life is one of the advantages of LED lighting energy saving. Low price may benefit in a short period of time, but if quality is not enough, quality problems will be sooner or later. According to the market feedback news in the first quarter, due to the safety hazard caused by insufficient insulation of the products, the European Commission issued a consumer warning to the Chinese-made Goobay brand LED light chain, and took measures to withdraw the market and recall the product.
In addition, from the results of the quality inspection of the energy-saving lamps and LED bulbs sold in Guangzhou City, the 26 samples of 46 samples were judged as the overall unqualified supervision, and the qualified rate was insufficient. 50%. To this end, industry experts said: the quality of LED lighting products below 30 yuan is difficult to guarantee. Apply the sentence in "Infernal Affairs": it is necessary to come back sooner or later.
Of course, China's LED industry can achieve such rapid development in just a few years, and many companies have deeply realized this and have been trying to open up a new route.
In the context of the industry's falling product prices in the domestic market, how to get rid of low-cost, disorderly competition, develop and produce more high-quality, high value-added, cost-effective products become the blue ocean that these enterprises seek in the fierce competition. Our products are on the high route, positioning the high-end market, do not do low-cost market, a LED power company responsible person said.
The market is classified by price, and the market can be divided into three grades: high, medium and low, each grade has different consumption needs. At present, the immature LED industry is often very passive in meeting customer needs, which also implies that enterprises need to further improve product performance, price, value and advancement of the industry.
