What should be noted that the use of waterproof LED switching power supply?
Waterproof type switching power supply range of applications in LED lighting field increasingly wide public, in practical applications, this new LED waterproof power supply not only has the constant current drive, the advantages of cold light illumination, its own security is also very high, It has become the first choice of public lighting facilities. So, this type of waterproof LED power supply, in actual use, and what issues need attention?
LED switching power supply using the drainage process, the engineers first need to note that, since the temperature rise LED switching power supply problem. Typically, the power supply equipment depicted in better temperature will remain at 25-30 ℃, the temperature difference between the comparison is depicted in greater than 35 ℃. Used in public places lighting and outdoor lighting waterproof LED switch power demand, the need to use sealed housing to protection class progress, manufacturers need to gluing process, not the same price colloidal material costs are not the same, not the same thermal function, cheap plastic thermal conductivity is poor, and requires high temperature baking, tend to form element equipment is not the same degree of stealth and tight strain injury, leaving dangerous.
Lamps from the temperature rise problem is also a big problem LED waterproof power supply when public lighting applications, the need to pay attention, because a lot of heat on the basis of their own LED happening housing to heat, a reasonable depiction of its LED lamps, its own housing a temperature of about 20 ℃ -25 ℃ between. That is, at room temperature 25 ℃ operating conditions, the temperature around the lamp housing is about 45 ℃ -50 ℃ is normal, if beyond the scope of this indicator, it shows that the product is defective in terms of temperature.
One problem to note here is that, at work, switching power supply electrolytic capacitors LED temperature rise every 10 ℃, life expectancy will be binary, it will directly affect their life. Currently there are relevant technical staff is not able to make use of ceramic capacitors or solid field of LED lighting, but with the current skills capacitance capacitors are unable to make these two high-voltage large-capacity, which is more regrettable. The number of capacitors used longevity may not be able to ensure that the number of life power, the power to raise life expectancy from the need to improve in many aspects, such as the use of a higher number of life capacitors, power supply progress, optimize the power supply cooling or heat lamps depicting depicting the like.
