In the blink of an eye, 2014 has entered the last month. What characteristics of the LED industry have shown in the past year, we analyze it from the five major segments. In 2014, the LED display field showed the following characteristics: 1. In the first half of 2014, China's LED display market changed little compared with last year, and corporate orders were relatively stable, but many SMEs' profits were in a low-profit state, and there were widespread difficulties in returning funds. The problem, triangular debt is still a common problem in the LED display industry. 2. The new market segment has become a new growth point for LED display companies. The outdoor advertising media, indoor small spacing and other market segments still maintain good growth, making the LED display industry maintain a certain growth. Such as Lehman Optoelectronics layout sports media field. 3, LED display small age small pitch LED screen. The world's major LED manufacturers began to compete to launch their own small-pitch strategy, and the prospects for small-pitch LED products are also optimistic at home and abroad. Among them, the high-density small-pitch LED display is an important emerging market in the industry, and it is also one of the markets with high profit margins. In 2014, the field of LED street lamps showed the following characteristics: 1. The overall environment of LED street lamps tends to be stable. However, due to many objective factors such as government change and anti-corruption, the LED street lamp propulsion speed is significantly lower than expected this year, and the growth rate is slowing down. The market is more rational. 2. Overall, LED street lights have made great progress in terms of overall road illumination, uniformity and glare control. However, due to the tight market demand and the huge base of LED street lamp manufacturers, the market competition is fierce. Larger enterprises, in addition to the quality of the LED street lamp manufacturers in the future is to fight the price, seeking new economic growth points is also the goal of the public LED street lamp manufacturers. 3. The structural design of LED street lights has changed, and the modularization of light sources has become a new trend in the future. The previous monolithic and modular design had to be replaced by the entire lamp once the luminaire had a problem, but only the electronic control part was replaced after the light source was modularized, although it did not save costs from the perspective of the single lamp, but the cost in the long run Lower. 4, the application of intelligent control systems on the LED lights gradually increased, many domestic and foreign companies began working smart lights LED lights R & D, such as Philips, GE and other international giants, Kingsun, Optronic and other domestic comer. Intelligent LED street lights can save energy in the original LED energy-saving technology, but the stability of the intelligent LED street light system is insufficient, the failure rate is doubled, and the system may be worse than the lights. In 2014, the LED chip/extension film field showed the following characteristics: 1. In the first half of 2014, LED chips continued to grow. At the same time, the concentration of LED chip industry is getting higher and higher, and the polarization phenomenon of domestic LED chip factories is becoming more and more serious. 2, three optical and BDO Runda led by mainland LED chip, wafer plants rise, the domestic LED chip has been gradually recognized by the local market, grab the original stage production of LED chip market share in the Mainland market. 3, LED chip design and manufacture to the small size, high current, low voltage, high lumen direction, the same optical effect, but of smaller size, or the same size, higher luminous efficiency. 4, limited market capacity determines the relationship between enterprises is a trade-off. Extension of the current LED industry, from chip to the package until the downstream applications, overall overcapacity situation has not changed, China's chip market is still digesting capacity. 5. The three quarterly reports of LED listed companies have been released in succession. In the first three quarters of this year, more than 50 LED chip factories have achieved good results. The listed LED chip companies are polarized. It is expected that the LED chip factory will change its market position in addition to the top three. In 2014, the field of LED light source showed the following characteristics: 1. LED tube and bulb became the top two LED light sources in China. China is the world's largest lighting production, sales and use country, and China's high-efficiency lighting products account for more than 80% of global production. The LED bulb market will continue to maintain a rapid development trend. 2, LED fluorescent tubes, bulbs and other conventional products to maintain the trend of price cuts, will be fierce price-performance competition in the next two years. Is expected to end 2015, with luminous efficiency of LED lamps and energy-saving price to the price of 1: 1 ratio, costs and prices continue to decline 30. 3. The sales volume of LED light sources in e-commerce channels is getting higher and higher, and more and more LED lighting manufacturers are developing e-commerce. 4, LED light source to the direction of intelligent lighting development. In 2014, the driving power supply field showed the following characteristics: 1. LED lighting drive power supply grew at a high speed. As of the end of 2013, the number of LED driver power companies in China exceeded 400. 2. The growth space is large, but the gross profit level continues to decline. Some power companies lack the power to release their performance, and LED street lamp power competition is becoming increasingly fierce. These companies are seeking transformation. 3. The market needs high quality LED driver power products. In foreign countries, customers are extremely demanding on the efficiency conversion, effective power, constant current accuracy, power supply life and electromagnetic compatibility of LED drive power. In China, the power supply market has gradually turned to the demand of high-end brands. In addition, since September 1, 2014, the LED driver power supply has been included in the scope of 3C compulsory certification. The implementation time of the 3C certification is September 1, 2015. The state has incorporated it into the 3C compulsory certification system, which means that LED power companies must meet the 3C certification standards before they can go on sale, which will be a blow to companies that do not follow the rules. 4. The modularization and intelligentization of LED power supplies has become a trend in general lighting. After the modularization of LED power supply, the cost will be lower, and the intelligence can meet people's living needs, such as dimming and temperature adjustment.
Designed to perform the shearing and removal of the excess of metal accumulated during the welding, leveling in a homogeneous way the portion of the welded rail. It consists of a powerful hand pump which moves two hydraulic cylinders with the mobile shearing blade applied on, that, during the removing of the material, leans against the fixed cutting blades. The cutting blades are easily replaceable so as to adapt the tool to the rail profile to be processed. Two handles are placed in a well-balanced point, allowing an easy movement of the machine.
