How to identify quality LED lighting products
LED lighting due to energy saving, high efficiency, long life and other features, more widely loved and accepted by consumers, but the domestic LED lighting market varies greatly, product quality big difference, there are a lot of inferior products flooding the market, for the ordinary consumers, how to identify the product quality is good or bad, make sure you buy a quality qualified LED lighting products? This reporter to investigate.
LED lamps in the testing process common quality problems sulfide, chemical incompatibility, dead lights and the light fades. If the vulcanization and chemical incompatibilities To troubleshoot lighting materials testing to identify suspicious materials, do validation experiments confirmed that the material is harmful to light the lamp. If you are dead lights and the light fades, the lamp should conduct a comprehensive examination of the failure to identify the cause of failure.
To identify whether testing organizations qualified LED lighting products in two ways: the first is the reliability of the test, by thermal shock, environmental simulation to identify the quality of lighting, but this method is a long period of time (3-6 months), the price expensive, but also could not find the real reason. The second is a material identification method, identification of quality products from defects in materials and find the angle.
Come from a professional technical professional organization to identify quality LED products, but for ordinary people, can only come through a preliminary identification of a simple way. A certain brand of LED lighting manufacturers told reporters, ordinary consumers to buy LED lamps can distinguish three aspects: look at the appearance, feel the temperature and listen to the sound, which can separate the good or bad quality.
First, from the appearance of lamps, the appearance should be no cracks between loose and interfaces are prized. During the installation, demolition process, there should be no loose or tilted cap phenomenon, light engineering plastics flame retardant plastic case must be selected, and the good quality of the material on its surface texture similar to frosted glass. Ordinary plastic surface is smooth, shiny, but easy to deform and flammable, is prohibited for the production of lamps.
The second is the touch temperature ,, LED lighting fixtures under normal operating conditions, the temperature should be relatively low, if the heat is not good condition, lamp work beads at high temperatures, light body will be hot, light will be great, lamp life will be greatly reduced. Meanwhile, when the lamp is lit and off, if there is rapid flashing, also shows that there are quality problems.
Third, listen to the sound LED lights working. Electromagnetic compatibility of electrical items must be adopted, however, the project to detect very complex, depending on whether the electromagnetic compatibility testing by the national flag on the packaging when the user to purchase lights. You can also simply a small trial judge, with a short-wave radio, when the LED lights work, the radio near the lower radio receiver to noise, electromagnetic compatibility test lamp explain better, in silent environment in listening to the sound of LED lamps at work, if you can very clearly hear the voice of the lights work, and also shows good lighting quality.
Finally, to remind consumers to buy lighting, be sure to go to regular stores and buy brand lighting, meanwhile, do not forget to ask for an invoice, voucher or purchase small ticket purchase lamps, and take good care of these documents to the complaint evidence of quality problems .
