Bo cause prompt when in operation bender, in addition to the above data outside pipe 250 watt sodium lamps factory production strength, elongation properties also need to master the production of street light pole material, pipe bender and bend jig / Wrinkle precision sheet adjustments, which are to be noted that, after all, we do not pipe elbow 90 degrees, but there is a certain level of compliance with handsome street light pole. For the selection of the bending machine, and now many manufacturers are using versatile bender. Light pipe can be bent into any curvature can be cold formed, no heating or filling sand process. Why bending machine is versatile, because you can bend the pipe and tube, this is for street lighting manufacturers for the production of shaped lamp is useful. And the performance is also superior arc smooth, clear, deformation is small, beautiful and which ensure that the products of the street pole surface is very important. In the process of street light pole bending steel material, there are few pay attention: 1, Street tube diameter must fit the groove with bending mode, or pole steel surface prone to clashing phenomenon; 2, when bent steel poles had bent over the best 250-watt sodium lamps where to find the location to put positive, both support wheels should be symmetrical positions, in order to ensure the smooth poles pipe in the groove shape. Pole on the street about the friends know, only in accordance with the drawings steel poles bent into a certain angle, capable of making the next lamp post. Now bending machines are CNC bending machine, but still needs attention to safety in the production process of street light pole, bending the rear of staff are not allowed to stay or residence, is not allowed to stand. Pole bending pipe to be compacted during pressing to prevent its tilt wounding. Bo-saving lamps cause prompt you really saving? First of all, we must be clear about the concept of energy-saving, accurate to speak in the same resolution (CRI light source equivalent) premise of effectively receive the same illumination unit area of ??power consumption The lower the light, the more energy-efficient. Of which there are several key points: first, the same clarity, sharpness depends largely on the color temperature of the light source, since the 5000K-6500K white light to maximize the reduction of the original color of objects, natural in the human visual clarity on higher. Why the emphasis on effective area, which is designed to light a problem, because a lot of light is 360 degrees or 180 degrees luminous light, and the angle of lighting we need may be 120 degrees or 90 degrees. Third, the same illuminance consumed less power, because the power company is based power tariff collection, of course, less power consumption and therefore the less, be pointed out that power with power factor is not directly related to the consumption of 250 watts sodium lamps, power factor does not affect the level of power, but the issue relates to line loss. Now we use these standards to weigh the energy-saving lamps, first look at the color rendering index, CRI universal saving about 70, pure three-color phosphor should be able to do about 75, should be in terms of the color rendering index is a good ; and look luminous efficiency, energy-saving lamps light efficiency generally in 45-50LM / W, pure three-color phosphor should be done 50-55LM / W; finally see the utilization of 250 watt sodium lamps price how do you know, since the energy-saving lamps a surface light source, the light emitting area is large, light itself is more difficult, besides saving lamps either spiral or U-tube light issued basically horizontal direction, and all we need light generally vertical direction, Hence the need for a big mirror to change the direction of the light cover to make it down the photos. How 250 watt sodium lamps cause of value _ _250 watt sodium lamps cause by Henan Bo Lighting Equipment Co. Henan cause Bo Lighting Equipment Co., Ltd.
