Waterproof LED switching power supply has become more and more widely used in the field of public lighting. In practical applications, this new type of LED waterproof switching power supply not only has the advantages of constant current driving and cold lighting, but also has its own high security. Has become the first choice for domestic public lighting facilities. Then, what kind of problems should be paid attention to during the actual use of this waterproof LED switching power supply?
In the process of using the LED drain switch power supply, the first thing that engineers need to pay attention to is the self-temperature rise of the LED switch power supply. Normally, the temperature rise of the better power equipment depicted by the power supply will remain at around 25-30 °C, and the poorer temperature rise depicted will be greater than 35 °C. LED switch power supply used in public lighting and field lighting needs waterproof, need to use sealed shell, in order to improve the level of protection, manufacturers need glue processing, different gel materials cost is not the same, thermal conductivity is not the same, The sale of rubber has poor thermal conductivity and requires high temperature baking, which often results in invisible damage and tight strain of the metadevice, leaving a danger.
The problem of self-heating of the lamp itself is also a big problem that needs to be paid attention to when the LED waterproof switch power supply is used in public lighting applications. Because a lot of heat generated by the LED itself relies on the housing to dissipate heat, and the LED lamp itself is reasonably depicted. The temperature is between about 20 ° C and 25 ° C. That is to say, under the operating conditions of room temperature 25 ° C, the temperature of the lamp housing is about 45 ° C -50 ° C is normal, if it exceeds this index range, then the product has defects in temperature rise.
One problem that needs to be paid attention to here is that, in the work, the temperature of the electrolytic capacitor of the LED switching power supply will increase by 10 °C, and the life will be half-folded, which will directly affect its service life. At present, there are related technical personnel in China who are suggesting whether ceramic or solid capacitors can be used in the field of LED lighting. However, with the current capacitive skills, these two capacitors cannot be made into high-voltage and large-capacity, which is quite regrettable. The use of long-life capacitors may not necessarily ensure the power life. To improve the power life, it needs to be improved in many aspects, such as using higher life-capacitance capacitors, improving power supply, optimizing power dissipation or heat dissipation.
