How to discern the stand or fall of LED street light products1

Many LED lights when the choose and buy, basically will be fooled by their prices as well as the appearance, don't know how to tell the good or bad, you say how to discern the stand or fall of LED street light products. Wavelength at the first,

the same LED wavelength, their color is almost the same, if the requirement is a special color, natural price will be higher. And if there is no LED light color separation instrument manufacturers, is also difficult to produce the color is more pure LED street light products.

the second, the leakage current of LED street lamp belongs to the one-way conductive lights, in the form of assumptions have reverse current, it is called leakage. If leakage current big LED street lamp, their life is short, nature price is lower, whereas the LED street lamp price will be higher. Third, light Angle

the LED street lamp USES different, their light Angle is not the same. If the LED street lamp light Angle is special, their price is higher is. Like a luminous and the diffuse Angle of 360 degrees, or is in the form of light distribution and so on all LED lights price will be much higher.

4, life want to make sure the quality is not the same as the LED street light where the key is to see their life, and life is determined by the light failure. Droop small LED street lamp life is long, life is long, certainly the price will be higher, and the average life span for the LED lights are longer than the traditional street lamp.

5, the LED chip LED may shine is because the chip inside, not the same chip, their price difference is very big. Such as the United States, the Japanese chip is expensive, and Chinese and Taiwanese manufacturers LED chip price is much lower, most of the LED street light price is focused on the chips, it is similar to the heart of LED street light.

in the end, the judge of the LED street lamp products is to look at the power of chip size, high power chips must be better than small power. Nature LED street light price is proportional to the chip power and choose and buy when it is good to note that these.
