Best Led Light Brands Trend Report

Football is a lot of people like sports, to have a lot of people every weekend football to play football. Same night there will be a lot of people want to go to the stadium movement, this time on the football field lighting requirements and high range is very large, so the course in general with more than 30 meters high


football is many people like sport, many people play football in the football field every weekend. At the same time, many people want to go to the gym in the evening. At this point, the lighting requirements and the length of a football field range is very high. Therefore, the stadium is usually equipped with more than 30 meters high lamp. Do you know how to configure them? Today, the high lamp series of small manufacturers will take your brother understand configuration method of high lamp on the football field. On structure design, the stadium of light, lamp plate and light pole is one of the mostly, because this kind of light, lamp plate, uneven distribution of weight is different from ordinary square high lamp, use 360 degrees; The circular lamp panel. Square light lamps are installed on a surface, that is to say, all are focused on a point, the weight of the whole lamp plate weight imbalance, this is also the stadium light, rarely designed to be the main reason for the lifting structure. Because it can't be designed to lift structure, high lamp manufacturers recommend the design of a total length of the ladder. Because of the use of the lamps and lanterns is inevitable there will be a problem, if there are no ladders, the lamp panel can't lift, maintenance costs will be high at a time. The stadium of light, lighting requirements are very high. We know a regular football field is 105 m * 68 m, the area of this means that the light irradiation ability must achieve the range of 50 meters, this is the normal 400 w high pressure sodium lamp cannot reach. The stadium of light, the most commonly used lamp is the big lamp, using 2000 w osram metal halide lamp, the price of a single tube is in 2000 yuan. Although the stadium lighting lamp without lifting function, but it much more expensive than the same height of lift light pole lamp. The key is the stadium lighting is much taller than other light pole in the configuration.

Often pay attention to our friends will know that in high lamp light, today small make up to you to introduce high lamp manufacturer security calculations, let's together to simply look at it. 1) Light, lamp plate ( Including the lamps and lanterns) Windward area: by




often pay attention to our friends will know that in high lamp light, today small make up to you to introduce high lamp manufacturer security calculations, let's together to simply look at it.
　　1) Light, lamp plate ( Including the lamps and lanterns) The windward area: because of the light plate with different shape, make the lamp panel of windward area is uncertain. Now take common enclosed flying saucer shaped lamp panel as an example, the lamp panel appearance of orthographic projection as the windward side reference area S lamp plate = ( d1+d2) H1/2;
　　2) High light pole of windward area: high light pole body tend to use ( Taper about 1000:5) Cone or cylinder solar led street lamp body. The wind area of the shaft that increases with the increase of shaft length. The body S = ( D1+D2) H2/2;
　　3) Light of the basic wind pressure is perpendicular to the plane of the airflow direction wind pressure calculation by wind pressure, according to the Bernoulli equation that the standard air pressure relationship formula. The wind of the dynamic pressure is: the WP = 0. 5*r*V2/g=0. 5*ro*V2( ro = r / g) WP for wind pressure, the unit KN/M2. Ro for air density, the unit KG/M3. V for wind speed, the unit is M/S. R for severe air, unit KN/M3.

Continuing the hot market last year, the LED industry was popular in the capital market. The logic behind the market speculation is that incandescent lamps will be banned in the United States from 2014, and LED lighting is expected to copy the European market last year. Industry insiders admit that the US sales channel is different from domestic, and market development is not easy. Despite this, Guan Yong, general manager of sunshine lighting, is still optimistic: In 2014, the profits of the whole industry increased by at least 20. Blue-chip the company performance will double 2013 LED lighting products in commercial lighting and home lighting field shine LED indoor lighting application the first time beyond outdoor landscape lighting to more than 80 of speed growth. The popularity of downstream lighting also benefits the middle and upper-stream enterprises in the LED industry chain. This year, commercial lighting will blossom and bear fruit, and home lighting will start quickly. Guan Yong is full of confidence in this year's market at the high-tech industrial investment strategy meeting. He believes that the opening of the downstream market will bring huge profits to the entire industrial chain, and the overcapacity of upstream chips has been effectively alleviated. In the past few years, local governments have introduced subsidy policies for imported LED epitaxial chip production equipment, resulting in a large number of outsourcing production equipment by upstream chip manufacturers, resulting in local overcapacity (Oversupply of medium and low power chips). However, the LED lighting market started last year and digested some of the production capacity. At present, the chip market is basically balanced. Zhang Xiaofei, president of Gaogong LED, said in an interview with reporters. Under this situation, Sanan Optoelectronics, a leading domestic chip manufacturer, recently launched a private placement to raise funds, doubling its original production capacity. For good enterprises, the profits in 2014 should at least double, and enterprises with a profit growth rate of only 50 may have problems. Guan Yong believes that the LED sector in the capital market experienced a round of gains last year, and most listed companies can fulfill market expectations this year. However, under the general trend of industry integration, small enterprises with weak financial strength will have a crisis. The traditional packaging manufacturers are facing a crisis. The director of Ruifeng Optoelectronics Technology, Xiaoming, has a premonition of the crisis in industry integration, but he believes that the crisis does not come from capital but from technological changes. With the transformation of Packaging Technology, traditional packaging enterprises will face a survival crisis. Pei Xiaoming said that chip-level packaging technology is beginning to rise in the industry at present. After this technology matures in the future, it may occur that upstream chip manufacturers directly skip packaging manufacturers to provide lamp beads to downstream application manufacturers. traditional packaging manufacturers in the middle reaches will be short-circuited. The integration of chip manufacturers and packaging manufacturers is an inevitable trend in the industry. Pei Xiaoming believes that at present, some manufacturers have begun to try to integrate the upper and middle reaches of the industrial chain, and some enterprises even have the integration of the whole industrial chain. For example, the chip manufacturer Tongfang shares recently acquired the Hong Kong Stock Company Zhen Mingli and expanded downstream. Guan Yong believes that the real purpose of TongFang's acquisition of zhenmingli is to take a fancy to the company's sales channels in overseas markets. The company's lighting products once accounted for 50% of overseas markets. Talking about the US market, Guan Yong said frankly: The US sales channel is mainly supermarkets, and domestic brands are difficult to enter the United States. At present, in the US market, the old lighting brands Philips, Osram and other products are still relatively strong, and LED lighting companies are also more prominent. Domestic companies enter the US market, mainly based on OEM. Zhang Xiaofei believes that the OEM mode is the process of the transfer of LED lighting production capacity in the United States to China. Although the profit margin is low, there is still room.
