LED tube can not be ignored several key issues
LED tube products have broad market prospects no doubt, especially in the lighting field. If the LED tube light is widely used in lighting the field would be a revolution in the history of mankind lighting. But by technology and other factors not currently widely. Lighting is now used in lighting the field of Led tube more and more today.
The reason why more and more widely with the advantages of LED light source itself are inseparable. LED tube light on energy saving, long life, no radiation (green light), etc., we should have a better understanding, here are a few with LED tube-related problems.
DC power supply should be used
Some manufacturers use in order to reduce product cost, “RC-buck” approach to the LED tube products, power supply, LED tube that will directly affect the life of the product. Using a dedicated switching power supply (preferably constant current source) to the LED tube power supply will not affect the product life of the product, but the product cost is relatively high.
Anti-static measures should be done
LED tube products in the process to be used during the production of certain anti-static measures, such as: bench to ground, the workers wear anti-static clothing, with anti-static ring, and with anti-static gloves, anti-static conditions can be installed ion fan, but also to ensure the plant is about 65% humidity, the air is too dry to avoid static electricity, especially the green LED tube relatively more easily damaged by static electricity. In addition, the different quality grades of LED tube antistatic ability is not as high quality LED tube grade antistatic ability is stronger.
Should pay attention to LED tube temperature will become smaller resistance
When the outside temperature increases and then, LED tube light source resistance will reduce, the use of regulated LED tube power supply will cause the operating current increases, when more than its rated current, LED tube will affect the life of the product, LED tube light source will make a serious, “burnt out”, so the best selection of current source power supply, LED tube to ensure that the operating current from the outside temperature.
Sealed LED products
Whatever the LED tube products, when applied to outdoor, are faced with waterproof, moisture-proof sealing problems if not properly handled will directly affect the LED tube product life. Now a small number of relatively high quality requirements of product manufacturers using the traditional epoxy resin “water” method to seal the LED tube products, this method is cumbersome to operate, for the larger LED tube products are not very suitable products can also cause weight gain.
LED tube control technology :
LED tube currently the most widely used control technique is the “serial communication” approach (to DXM512 protocol based). The advantage is that each light rails no specific “code” can be any exchange between each to facilitate the production and installation. But its biggest drawback is that if there is a damaged, it will directly affect all the fence behind the lights, as in the single lane of cars on the highway, if there is a car “broke down”, it will cause all the cars behind it can not be normal operation. For the hundreds or even thousands of meters of Led tube works, due to external factors and the quality of the product itself and other factors, it is difficult to ensure that every problem is not a Led tube, so it is likely to cause “traffic paralysis” phenomenon.
In addition, the next LED tube light source on the market today The quality varied widely, not only of good quality and high brightness LED tube light, light decay is also small, anti-static capability also strong, will determine its long life, but its price LED tube light than cheaper several times higher. We will often see some LED tube lighting project at the beginning is indeed very beautiful, but soon “incomplete incomplete,” and some delays can not even hand over the project. Therefore, manufacturers and users not in the price, “flame.” Use good quality LED tube light, take effective measures to ensure the technical quality of the products LED tube is the way out.
