LED underwater light is a kind of low water filling. Simple refers to the light installed in water and water. The appearance is small and exquisite, beautiful and elegant. The appearance is similar to some buried lights, but there is more installation chassis. The chassis is fixed with screws. Because the LED lamp underwater light is used under the water bottom, it needs to bear a certain pressure, so it is generally made of stainless steel material, 8-10MM tempered glass, high quality waterproof joint, silicone rubber sealing ring, curved multi-angle refractive tempered glass, waterproof, Dustproof, leakproof, and corrosion resistant.
LED underwater light range: large swimming pools, fountains, aquariums and other places for underwater lighting.
LED underwater light purchase considerations
Due to the particularity of underwater lantern applications, it is an electrical product that works underwater, so it also has special requirements for its technical indicators.
First, the protection indicators of underwater lanterns: the protection indicators of underwater lanterns are divided into two aspects: dustproof and waterproof. The IEC standard stipulates that the international common protection marking symbols are as follows:
1. Dust-proof level: According to the national standard, the dust-proof level of the lamps is divided into 6 levels. The sixth level is the highest, and the dust level of the underwater lantern should reach level 6 with the symbol: IP6X.
2, waterproof rating: national standard regulations, the waterproof rating of the lamps is divided into 8 levels. Level 6 which is a type of water splashing, led lights having the order of 7 watertight, the watertight 8 is pressurized. The eighth level is the highest, and the waterproof level of the underwater lantern should reach the level 8 requirement, and the symbol is IPX8.
In combination with the above two requirements, the underwater lantern has a dustproof rating of 6 and a waterproof rating of 8 and its symbol is IP68.
Second, anti-shock safety indicators: National standard on the anti-shock indicators of lamps are divided into four categories: namely O, I, II, III. At the same time, the national standard clearly stipulates that underwater lighting fixtures for swimming pools, fountains, splash pools and the like should be protected against electric shock. The operating voltage of its external and internal lines should not exceed 12V.
Third, the rated working voltage: the rated working voltage of the lamp is the indicator of the electrical parameters of the lamp, which directly determines the environment in which the lamp is used, that is, the actual working voltage must be consistent with the rated working voltage. Otherwise, it is not because the voltage is too high to burn out the light source, or because it is too low to achieve the illumination effect of the light.
The choice of LED underwater lights should consider the following aspects:
1. Safety function: In the landscape place, the choice of LED underwater light takes personal safety as the first element. LED underwater lights with 12V safe voltage must be used in accordance with the requirements of the national standard.
2, lighting function: lighting function mainly refers to the light level 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 underwater lanterns. 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: underwater lights, although used underwater, 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 underwater lantern is easily loosened, so that the lamp floats on the water surface and is too heavy to make the lamp frame 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. Economical: The economics of underwater lanterns refers to the sum of one-time investment and operating expenses of lamps. Generally speaking, the underwater light with better quality has higher lamp price, longer service life and lower operating cost. On the contrary, the underwater light with poor quality is cheap, but often due to water leakage and leakage. Leading to blindness, not only increased operating costs, and some even affected the acceptance of the entire project.
LED underwater light installation precautions
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 situation is for LED water. The lights don'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, such as: workbench should be grounded, workers should wear anti-static clothing, with anti-static ring, and with anti-static gloves, etc. Install an anti-static ion fan, and also ensure that the air humidity during installation is about 65%, so as to prevent the air from being too dry to generate static electricity. In addition, the antistatic ability of LEDs of different quality grades is also different, and the antistatic ability of LED underwater lamps with high quality grades is stronger.
3, should pay attention to the sealing of led products . No matter what kind of LED lighting products, as long as they are used outdoors, led lamps are faced with the problem of moisture and sealing, especially for LED underwater lights. Poor handling of sealing problems will directly affect the service life of LED underwater light products.
