Matters needing attention when the choose and buy led lights1

With the progress and development of science and technology, now appeared on the market all kinds of street light, led street lamp is one of them. Has come under the market economy, the emergence of a large number of manufacturers. In the face of the lamps and lanterns of mixed, when the choose and buy, how should we do? Take a look at it.

a, luminous efficiency

is affect the led street lamp luminous efficiency and energy saving effect of key factors, everyone will know that the higher the efficiency, the better its effect of energy conservation and emissions reduction will be. So, when the choose and buy special attention should be paid to it. See the description about the interpretation of the luminous efficiency first, at present our country's most advanced led the luminous efficiency of lamps and lanterns in 80 lm/W. If there is no this explanation, that is about to find manufacturers, let them give yourself a detailed instructions.

2, weight of that type street light will weight will be heavier than ordinary street lamp, and manufacturers are weight research, hoping to improve the condition of this kind of heavy. I believe that in the future development of relevant manufacturer will do more and more good. At present, the manufacturer from the initial 30 kg. Now more than 10 kilograms. You can see, they are trying hard to double.

3, the stand or fall of cooling

cooling function has direct influence on the service life of lamps and lanterns, according to the current technology, the best is acicular heat dissipation technology, and there have been many manufacturers use, in the future, there will be more manufacturers to join the industry. According to the survey, the street lamp with good heat dissipation function, the maintenance work done, the service life of it in 10 years. So, it is necessary to heat, when the choose and buy must pay attention to. Four, light failure

power of lamps and lanterns, light failure will be better, if the light failure rate as high as 80%, then the lamps will be scrapped, almost no usable value, the service life of it's just a few months. So when the choose and buy, pay attention to the light failure.

these are considerations led lights when the choose and buy, only choose good product, can benefit from. If the lamp is unqualified, not only change the trouble, but also increase my cost.
