Use led underwater light should attenton as blows:
1.The choice of LED underwater lights should be used constant current power supply. Under the control of constant current power supply, the forward voltage drop of LED wall washer, LED flood light, LED underwater light and LED underground light will become smaller as the temperature of LED chip increases, so the situation for LED water The lights did not have much impact. However, if it is constant voltage drive will cause the LED underwater light chips with the current temperature increases, the situation may even be serious, burning LED underwater lights. Therefore, LED underwater lights should be used for constant current power supply.
2.For lighting housing selection, pay attention to lamp control, supply voltage, single lamp power consumption.
3.Calculate the cable diameter: especially the use of low-voltage power supply lamps, so it involves the low-voltage high-current power supply will affect the line pressure drop, you must first calculate the pressure drop at the end of each line, stay ahead of redundancy.
4.The underwater light power supply isolation transformer and leakage switch must be arranged outside the 2, in order to avoid electric shock accident.
5.Either Ming-mounted (scaffolding underwater lights) or installation (embedded underwater lights) should be reserved for 0.6-1 meters long cable, so as to avoid problems in the future lamps, you need to let go of the water in the pool, so Even if the lamp is broken, the lamp can be mentioned from the water to make the connection with the wiring and wiring waterproofing. When installing the lamp, be sure to install the lamp in a smooth mechanism, prohibit the installation in a strenuous exercise environment.
6.The wiring must distinguish between the power cord and the control line isolation, to avoid unnecessary interference.
7.The connector must be waterproof when the connector, or may not be closing, line loss increased, and even burn the cable phenomenon.
