In the process of using the waterproof switching power supply, the first thing that engineers need to pay attention to is the self-temperature rise of the switching power supply. Normally, the temperature rise of the better power equipment depicted by the power supply will be kept at about 25-30°C, while the temperature rise of the poorer depicted will be greater than 35°C. The switching power supply used in public lighting and outdoor lighting places needs to be waterproof, and a sealed enclosure is required. In order to improve the protection level, the manufacturer needs to fill the glue. The price of different colloidal materials is different, and the heat conduction function is also different, which is cheap. Selling glue has poor thermal conductivity and requires high-temperature baking, which often results in invisible damage and tight strains of different degrees of equipment, leaving danger.
One problem that needs to be noted here is that during work, every time the temperature of the electrolytic capacitor of the switching power supply rises by 10°C, the life span will be halved, which will directly affect its service life. At present, related technical personnel in China have proposed whether ceramic or solid capacitors can be used in the lighting field. However, with the current capacitor technology, neither of these two types of capacitors can be made into high-voltage and large-capacity, which is rather regrettable. However, the use of long-life capacitors may not ensure the power life. To increase the power life, improvements need to be made in many ways, such as using capacitors with higher lifespans, increasing power supply power, optimizing power supply heat dissipation, or lighting heat dissipation, and so on.
