T8 led products, several problems can not be ignored

T8 led products have broad market prospects no doubt, especially in the lighting field. If the led light source 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. Now used in lighting products, led lighting more fields, such as led guardrail lamps, led lawn light, led lighting, led underwater lights, led buried lights.


The reason why more and more widely with the advantages of led light source itself are inseparable. led light on energy saving, long life, no radiation (green light), etc., we should have a better understanding, the following led products with several problems related.

Some of the DC power supply should be used in order to reduce product costs the manufacturer a "RC buck" approach to led products, power supply, this will directly affect the life of led products. Using a dedicated switching power supply (preferably constant current source) to power led products will not affect the product's life, but the product cost is relatively high.

Anti-static measures should be done in the processing of led products 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, conditional The anti-static ionic air blower can be installed, but also to ensure that the workshop about 65% humidity, the air is too dry to avoid static electricity, especially the green led is more likely to be relatively static electricity damage. In addition, the different quality grades are not the same led antistatic ability, quality, high-grade led antistatic ability is stronger.

Should pay attention to led temperature will become smaller when the external environment resistance temperature after, led light source resistance will reduce, the use of regulated power supply will cause led operating current increases, when more than its rated operating current , will affect the service life of led products, led light source will make a serious, "burnt out", so the best selection of current source power supply, to ensure that the work of led current from the outside temperature.

led products, led products, sealed no matter what, when applied to outdoor, are faced with waterproof, moisture-proof sealing problems if not properly handled will directly affect the life of led products. Now a small number of relatively high quality requirements of product manufacturers using the traditional epoxy resin "water" method to seal the led products, this method is cumbersome to operate, for the larger led products (such as led fence light) not very suitable, can also cause weight gain products.

led fence light led fence light control technology is 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 the fence light engineering, 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 light rails, so it is likely to cause "traffic paralysis" phenomenon.

In addition, under the current market is good or bad quality of led light sources vary widely, not only of good quality and high brightness led light source, light decay is also small, anti-static capability also strong, will determine its long life, but its price is cheaper than The led light source several times higher. We will often see some led 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." Choose good quality T8 led light source technology to take effective measures to ensure the quality of T5 led products is the way out.
