"China's lighting industry is in a period of rapid development. More enterprises with high economic strength and high management level are bound to improve the overall level of the industry." Liu Shengping, secretary general of China Lighting Association, said in an interview with reporters recently. At present, China's lighting industry has problems such as low industrial concentration, research and development capabilities to be strengthened, and product quality to be improved. The industry as a whole needs to be integrated and upgraded.
It is understood that in recent years, the output value of China's lighting industry has grown rapidly. According to statistics from the China Lighting Association, the annual sales of China's lighting products has exceeded $38 billion. Among them, the growth rate of LED is particularly alarming. In the first quarter of this year, the output value of LED applications in China was 19.9 billion yuan, a year-on-year increase of 42%.
“Undoubtedly, the lighting industry has ushered in new opportunities for rapid development. However, there are still too many areas in the industry for marketing and brand building. The entry of big brands can inject new strength into the lighting industry. The national brand of its own is of great significance. According to Liu Shengping, the current status of the lighting industry is that almost no lighting company has a market share of more than 2%. When it comes to brands, people often think of "foreign brands" such as Philips and Osram. Although in recent years, domestic companies have gradually begun to focus on brand building, however, compared with mature industries such as home appliances, there may be a long way to go.
According to the data, the new base invested by the US for 500 million yuan will be mainly used to produce energy-saving lamps. After the project is completed and put into production, it is estimated that the annual production capacity will not be less than 200 million, and it is expected to achieve a sales scale of 2 billion yuan. Midea said that lighting electrical is positioned to do industry quality, will not participate in the existing market competition through low-cost, low-end products, and will not repeat investment and construction of low value-added or backward industrial chain, and will focus on LED research and development in the future. And production, committed to providing consumers with energy-efficient green lighting products.
"In a low-carbon, environmentally-friendly social and economic environment, more responsible companies need to actively implement and work hard to build a green industry, and the lighting industry, which is in a period of rapid development, needs the demonstration effect of the first sheep." Liu Shengping said that with The world's focus on energy-saving emission reduction and low-carbon economy, industrial upgrading and technological innovation in the lighting industry is imminent. Midea's entry into the lighting industry will make new contributions to the overall development of the Chinese lighting industry. With the continuous investment of Midea in the lighting industry, Guixi may even become another important production base of the domestic lighting industry after the five major production areas of Guangdong, Zhejiang, Jiangsu, Fujian and Shanghai, and will include supporting supply chains. The entire industrial chain, including production technology and R&D investment, has a positive impact from many aspects.
During the '11th Five-Year Plan' period, the state supported high-efficiency lighting products to replace incandescent lamps and other inefficient lighting products with high-efficiency lighting products, which accelerated the promotion and use of high-efficiency lighting products. Benefited from infrastructure construction such as Shanghai World Expo and Guangzhou Asian Games. Pulling, China's lighting industry may enter a new round of gold (1192.60, 4.40, 0.37%) development period."
First of all, industry companies should work hard to improve product quality and focus on transformation and upgrading.
Second, strengthen corporate brand building.
Third, increase innovation, strengthen management of production links, and focus on protecting the environment.
Fourth, industry enterprises should further strengthen norms and self-discipline, and establish an internal self-discipline evaluation and guarantee system.
In order to enable industry enterprises to take the lead in the fierce market competition and remain invincible, we should further accelerate the application and promotion of energy-saving products in the lighting industry.
The structure of the core barrel is generally divided into single - acting double core tube and most of the fishing apparatus. The double tube section consists of an outer tube assembly and an inner tube assembly. The outer pipe assembly includes; The main structure and working principle of the cartridge stopper, cartridge chamber, stable joint outer pipe, diamond reamer and diamond bit are as follows:
(1) Spear structure is composed of spear head and recovery spring. When coring, the fishing device is lowered to the upper part of the inner tube assembly in the drill pipe, and the fishing hook grasps the fishing spear, lifts the fishing device up, picks up the recycling card barrel, and inwardly compressing the cartridge card, so that the inner tube assembly and the outer tube are separated, so that the inner tube assembly is lifted up.
(2) The clip structure is mainly composed of the clip frame, clip, spring and other components. Its function is that when the inner tube sits on the outer tube, the clip expands with the help of the elastic force of the expansion spring and sticks to the inner wall of the clip chamber, so that the drilling tool can achieve positioning.
(3) Buffer structure by spring, locking mother, split pin composition. Protecting the inner tube when pulling the core.
(4) Single action structure is realized by two pairs of thrust bearings.
(5) Adjust the length of the inner pipe assembly and the outer pipe assembly of the structure, and fine-tune the lower shaft and the locking mother to achieve the gap required by the end of the spring seat and the step inside the drill bit.
(6) The fishing structure, also known as the fishing device, is mainly composed of fishing hook, hammer and safety rope. The fishing hook is used to hold the spearhead while fishing the inner pipe, and the weight is used to speed up the fishing device's descent to save fishing time. The safety rope is a thin rope. When the inner pipe is stuck for some reason and cannot be lifted, the safety rope can be forcefully lifted and then the drill can be lifted.
