Q:LED underwater lamp features of LED underwater lamp

LED underwater lamp shall be powered by DC constant current power supply. In the constant current power supply under the control of LED wall lamp, LED lamp, LED underwater lights, LED lights buried according to the pressure drop increases with the temperature of LED chip becomes smaller, so the situation is not too large for LED underwater lights. But if it is a constant voltage drive, it will cause LED underwater lamp chips to increase with the temperature, the current is increasing, and in serious cases may even destroy the LED underwater lamp. Therefore, the LED underwater lamp should be powered by DC constant current power supply.

Q:LED how many protection levels does the underwater lamp have?

Protection grade of concrete, is the need to test the side can draw the conclusion that the common LED is divided into IP20, IP40, IP65, IP68, if LED underwater lights, at least to just above IP65, IP higher level of security, if the product quality is good, IP65 can meet the.

Q:How to arrange and install a fountain lamp?

Q:LED what's wrong with the underwater light?

Waterproof when installingSometimes customers say that the lights are broken, and in the field inspection, it is found that some of the wire skin has been obvious water.

Q:Installation method of underwater lamp and matters needing attention

First of all, for lamp type selection, we should pay attention to the water resistance of the lamp, the power supply voltage and the power consumption of the single lamp

Q:What are the components of the LED underwater light source?

The last one to use 5630 beads, each 0.5W, usually used as a floodlight (such as lamp, lamp panel, Mian Guangyuan), the lens is relatively small, with a kind of light diffusion plate.

Q:What is an underwater light? What's the English name of the underwater lamp?

Because LED underwater light is used in the water below, to withstand the pressure, it is generally made of stainless steel materials, 8-10MM tempered glass, good waterproof joint, silicone rubber seal, multi angle refraction curved glass, waterproof, dustproof, anti leakage, corrosion resistance.

Q:What are the main parts of LED spotlights?

LED spotlights generally less power, only a few watts, it is not suitable for large area lighting. Before the lamp is halogen lamp light source, there are 20W, 50W, 71W of different specifications, LED light source than halogen lamp with high light efficiency, about 1W is equivalent to the original 5W, this is the current high technology, possible future development, you have to do, more suitable for local lighting.

Q:How to do waterproof treatment for underwater lamp joint?

After filling the waterproof and filling adhesive, the outer layer of the filling rubber is wound with a self adhered waterproof adhesive tape or stretched with self adhered waterproof adhesive tape to wrap the multi-layer, but the thickness is not too thick, so as not to be too large, and the insulating sleeve is not allowed to enter.
