1. Waterproof level
The first point we should pay attention to is the waterproof level. Not all lamps can be used as underwater lights. Let’s look at the dustproof and waterproof performance of a lamp. It mainly depends on the two digits behind IPXX
Dustproof grade from 0 to 6, the highest grade is 6;
In terms of waterproofing process, full glue filling is one of the common waterproofing processes in the manufacture of underwater lights. Under the protection of the colloid, it provides a better waterproof effect.
However, this kind of process is a double-edged sword. Because the epoxy resin is prone to chemical reactions in high-temperature environments, the lamp surface will turn yellow, which will affect the lighting effect, and its sealing will also lead to insufficient heat dissipation.
Therefore, it is a good choice to choose this type of swimming pool for ordinary swimming pools, while for hot spring pools and high-temperature pools, it is best to choose lamps with high temperature resistance.
2. Heat dissipation process
Generally speaking, aluminum substrates are used inside the lamps to enhance their heat dissipation performance. The higher the thickness of the aluminum substrate, the stronger the heat dissipation capability.
Common underwater lamps on the market generally use an aluminum substrate with a thickness of about 1mm, while our WM-SS168 uses an aluminum substrate with a thickness of up to 3mm, which can withstand a high temperature of 55°.
For some small lamps, when using high-power lamp beads, it may not be enough to use aluminum substrates as heat sinks. In order to provide stronger heat dissipation capabilities, copper substrates can also be used as radiators, which are more heat-dissipating than aluminum substrates. stronger, but more expensive.
In addition, the heat dissipation of the lamp is also related to the contact relationship between the lamp and the ground. In order to improve the heat dissipation performance, some high-temperature swimming pool lights will use more complex mold structures to increase the contact area with the ground and improve the heat dissipation effect, so as to avoid excessive operating temperature. Burn out lamps.
