Water proof LED switching power supply is widely used when using need to pay attention to

Waterproof model LED switching power supply applications increasingly widespread, in the field of public lighting in the actual application, this new type of LED waterproof switching power supply with constant current drive, not only the advantages of cold light lighting, its security is also very high, has become the first selection of domestic public lighting facilities. So, this kind of waterproof LED switching power supply, in the process of actual use, and what are the problems need to pay attention to?

in the process of the water use LED switching power supply, the first need to the attention of engineers, is the problem LED switching power supply, autologous temperature rise. Normally, the power of good power equipment will remain in 25 - temperature rise Around 30 ℃, describe more bad of the temperature rise will be greater than 35 ℃. Used in places of public lighting and outdoor lighting LED waterproof switch power supply, demand, need to choose sealed enclosure, in order to the progress of the protection grade, manufacturers need to deal with the glue, not the same as colloid material capital is not the same price, function of thermal conductivity is not the same, cheap glue, poor heat conduction function and high temperature baking, yuan equipment often forms different degree of invisible injury and a tight beam strain, leave the danger.

the temperature rise of the lamps and lanterns of autologous problems are also LED waterproof switching power supply in the public lighting applications, need to be aware of the big problem, because the LED to many of the heat itself is relying on the shell heat dissipation, reasonable description of the LED lamps and lanterns, its shell temperature is about 20 ℃ - Between 25 ℃. That is to say, under the condition of room temperature 25 ℃ homework, shell temperature of lamps and lanterns is about 45 ℃ - About 50 ℃ is normal, if beyond this range of indicators, so that the product defects in terms of temperature.

here need to be aware of a problem is, in the work, LED switching power supply, electrolytic temperature every 10 ℃, stature will halve, will directly affect the service life. There are related to the current domestic technical personnel put forward if we can use the ceramic or solid capacitors in the field of LED lighting, but with the current capacitance skills both capacitance high voltage large capacity can't make it, it is sadly. While the use of long life spans of capacitance are not necessarily can ensure power become old, yea, to improve the power full needs improvement in many ways, such as using high stature capacitance, the progress of power supply power, optimization of power depict cooling or heat lamps and lanterns, etc.
