How to simple judge the quality of LED lights
As countries push for LED lighting, led street lights wholesale products rapid growth and popularity.Because of LED products is the new production of lighting industry, ordinary people for its very strange, manufacturers and sellers of the even part of the technology is not very good, just explain to the customer, leading to the ordinary user misunderstanding of LED lighting products, brought LED products promotion and use of certain obstacles.Help users understand and judge the quality of the LED products, here are 10 simple leds quality stand or fall of discrimination methods.1, from the brand of choice.Should choose takes the “R” brand name or trademark has been registered enterprise products, LED lights appearance luster, the fine product brand, model, specification printing is clear and beautiful, there should be no deformation off paint, color is not equal.2, T5 LED lights usually USES the aluminum radiator, radiator and air contact area is larger, the better, is conducive to heat dissipation, so the whole lamp work stability, droop small long life;Ball steep and smallpox lamp don’t have too much air holes, climb into, in order to avoid in the process of using mosquito influence lighting effect or cause unnecessary damage.3, LED bulb, ceiling lamp, shoot the light, if light on the white walls, there should be no splash, color circle, such as obvious color temperature error, if you have this kind of phenomenon, said lamp bead light source of inferior.4, when open the T8 LED lights, electricity and light have zero a few seconds to the time difference between the two seconds, is normal phenomenon, the lamp is usually driven by constant current source with IC integrated circuit, its steady flow regulator, the performance is good, steady job.5, working lamp body fever don’t too high or uneven, if has this kind of phenomenon, said lamp design or production process has a problem, droop big damage easily.6, due to the high brightness leds, two brands of the same type lamp, under the same condition, with his eyes look straight comparison method of observation, it is difficult to judge the brightness of high and low, at the same time, it is easy to damage eyes vision.Usually we recommend to cover the light source with a piece of white paper, through the white light attenuation, compare again, so it is easier to see the brightness of the light difference, the higher the brightness of the better.In addition, the color temperature close to the color of sunlight is the best.7, if time allows, you can take the same specifications of the two lights do first brightness, then one of the lights light up a week in a row, and then compared with before the lamp brightness compared, if there is no obvious darker, illustrate the light failure is small, light bead light source quality is better.8, for those smallpox to shoot the light, track light, high-power integrated light source, COB high-power light source, and can easily remove the mask to see lamp bead more chips, which can use see lamp bead light source such as electric light after close your eyes, shut off the power at the same time opened his eyes again, will see the light bead chip corner, if corner disappear time error is too big, said light bead chip quality is uneven, or FuPin inferior light bead chip.The whole lamp is easy to damage the life is short, not easy to buy.Around 9, LED lights at work, have a high-power electrical appliances such as refrigerator, air conditioner, water heater starts, there should be no brightness change subsequently, if has this kind of phenomenon, the led street lights wholesale is not constant current or constant pressure, so to have a certain effect on the lifespan of lamp.10, society a screen mobile phone use camera to observe the LED lights to judge the good or bad, so judge of lamp is not too accurate, stripe rolling blinking positive is bad, no stripe rolling blinking are not necessarily good, because we are different and cameras, the phone’s screen, which they scan the refresh rate is different, for those low resistance capacity step-down drive products, their sensitivity is not the same.
