Bo tells cause LED street light for the study has been uninterrupted, research on small series light source is also very concerned about the progress of the research can be largely reflected in the horizontal direction and development of the development of this industry, in the following articles and we talk about some of the research questions about the industry. Spectral energy distribution of the light source to a recent test showed the presence of spectral energy is mainly reflected in the impact on facial identification. One study varied by changing the LED light on the human face of vertical illumination changes to test facial recognition ability of different SPD LED light source. Previous articles have mentioned, emitting blue LED lighting is the human eye is damaging. For facial recognition, it was found, too, the blue content is higher the more negative facial recognition, but is less favorable. When using LED lights long here that refers to the use of long life LED lights lights factory, before the introduction of LED lights very little about the life of the issue, of course, except street light pole, street light pole after the test is relatively simple, but the LED lamp life Calculation is relatively difficult, professional and technical personnel to use IES TM21 and boundary function were calculated to test Zhengzhou 250W sodium lamps manufacturers, projections certainly there are some flaws, so now the research study, the test conditions accelerated methods to test products life but will be more accurate. LED street light illumination range study involving two faces, a model of reflective glass factory in Zhengzhou 400W metal halide lights, one is irradiated surface. A lens reflector cup Riga, add the irradiated surface illumination grid. The researchers observed through the relationship between the size and half-light LED illumination, and to make a final judgment. Cause Bo think the traditional steel street light pole Zhengzhou 400W sodium lamps manufacturers, in fact, is still very popular. And here we said the new steel street light pole means a toggle-type steel street light pole, street light pole because the general life mostly in a decade, while the toggle steel street light pole, although in 2001 when he applied for a national patents, but the real starting time has been widely used or shorter. In this article, the author from the ordinary steel street light poles and light poles to distinguish the new process design and use of the presentation: Pole production process: General: The tube is bent into Shuhei blank ends, at one end welded on bottom flange and ribs, plasma cutting kerf to ensure a straight line. Socket weld and in the middle of the door lock to keep the level above. According to national standards for galvanized poles, street light pole ensure a smooth surface, no color, can not have sagging. After the spray galvanized street light pole polished surface with a polishing wheel. New: support shaft end consolidation sphere has two steel discs, the support shaft in which the force is transmitted. And then places it on the inner poles to steel disc cue lower end of the support shaft (made mostly of stainless steel) and on the circumference of the coupling poles fixed to the lower end of the support shaft ball sphere into the support base of the inner sphere circle then circumferentially welded and fixed, so that the light pole, the ball support shaft and the support base connections combined into one; then from the upper end of the support base into the next section in the lower section of the lamp socket holder, and fixed at its circumferential welding. Streetlight poles of service use: Normal: servicing or maintenance, the need to lift vehicles and aerial work (generally street construction team have a special 14 m / 16 m altitude vehicles and street maintenance vehicles). In this process, involving the unloading, cranes, lifting, not only costs of working hours, but also difficult. If the non-governmental sector, the need to find a professional street construction units are divided for each street light pole charge. Zhengzhou 150W metal halide lights manufacturers | cause (certified) | streetlights cause manufacturers to provide by the Henan Bo Lighting Equipment Limited. Henan cause Bo Lighting Equipment Co., Ltd. (www.zzdybcdj.com) is Zhengzhou City View light fixtures leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the cause of the leadership with the staff warmly welcome all inquiries negotiations to create the great cause of a better future.
