Underwater lamp produced by LED technology
- Sep 10, 2018 -

LED underwater lights are generally LED light sources. LEDs are called fourth-generation lighting sources or green light sources. They are energy-saving, environmentally friendly, long-life, and small in size. When it is powered on, it can emit a variety of colors, colorful, usually in a park or fountain pool.

  The LED underwater light is a underwater light produced by LED technology. Compared with traditional underwater lights, LED underwater lights are more energy-saving and environmentally friendly, and the lights are more varied and decorative, and they are widely used in various landscape lighting systems. However, as a manufacturer of LED lamps, some problems in the installation of LED underwater lights require special attention.


1. LED underwater lights should be powered by DC constant current power supply. Under the constant current power supply control, the forward voltage drop of the LED wall washer, LED flood light, LED underwater light, and LED underground light will become smaller as the temperature of the LED chip increases. This is the case for the LED underwater light. It doesn't have much impact. However, if it is a constant voltage drive, the LED underwater light chip will continue to increase with the increase of temperature. In severe cases, the LED underwater light may even be burnt. Therefore, the LED underwater light should be powered by a DC constant current power supply.

2, need to do anti-static measures. LED underwater light products should adopt certain anti-static measures during processing and installation. For example, the workbench should be grounded, workers should wear anti-static clothing, anti-static ring, and anti-static gloves, etc. Anti-static ion fan, also ensure that the air humidity during installation is about 65%, so as to avoid the air being too dry to generate static electricity. In addition, the antistatic ability of LEDs of different quality grades is also different, and the anti-static ability of LED underwater lamps with high quality grades is stronger.

3, pay attention to the sealing of LED products. No matter what kind of LED lighting products, as long as they are used outdoors, they are faced with the problem of moisture and sealing. This is especially true for LED underwater lights. Poor handling of sealing problems will directly affect the service life of LED underwater light products.


1, security features

  In the landscape, the choice of LED underwater lights takes personal safety as the first element. LED underwater lights with 12V safety voltage must be used in accordance with the requirements of the national standard.

2, lighting function

  The lighting function mainly refers to the brightness of the light source. It can select different power LED underwater lights according to the illumination height and the light projection area. Another element of the lighting function is the color of the LED underwater light. Generally, there are five kinds of red, yellow, green, blue and white, which can be selected according to the application, the object to be illuminated and the atmosphere created.

3, appearance and shell material

  Although the LED underwater light is used underwater, it is not very noticeable. However, the appearance and material are related to the specific gravity of the luminaire. If the specific gravity is too small, a large buoyancy is generated, and the fixing screw of the LED underwater light is easily loosened, so that the floating surface of the LED is too heavy and the lamp holder is difficult to support. At the same time, due to long-term use in water, the shell material should have a certain anti-corrosion function, and the surface paint layer should be firm.

4. Economics

 The economics of LED underwater lights refers to the sum of one-time investment and operating expenses of lamps. In general, LED underwater lights with better quality have higher lamp prices, longer service life and lower operating costs. Conversely, poor quality LED underwater lights, although cheap, often cause blindness due to water leakage and leakage. Not only increased operating costs, but some even affected the acceptance of the entire project.
