LED underwater lights are generally LED light sources. LEDs are called fourth-generation lighting sources or green light sources, which have the characteristics of energy saving, environmental protection, long life, and small size. When it is energized, it can emit a variety of colors, colorful, and is usually installed in a park or fountain.
LED underwater lights are underwater lights produced by using LED technology. Compared with traditional underwater lights, LED underwater lights are more energy-saving and environmentally friendly, and the lights are varied and more decorative, so they are widely used in various landscape lighting systems. However, as a manufacturer of LED lamps, some problems in the installation of LED underwater lamps need special attention.
1. The LED underwater light should be powered by a DC 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 decrease as the temperature of the LED chip increases. It didn't have much impact. However, if it is driven by a constant voltage, the current of the LED underwater lamp chip will continue to increase as the temperature rises. In severe cases, the LED underwater lamp may even be burned. Therefore, the LED underwater light should be powered by a DC constant current power supply.
2. Anti-static measures must be taken. Certain anti-static measures must be taken during the processing, production and installation of LED underwater light products, such as: the workbench must be grounded, workers must wear anti-static clothing, anti-static rings, and anti-static gloves, etc., can be installed if conditions permit For the anti-static ion fan, at the same time, ensure that the air humidity is about 65% during installation to prevent the air from being too dry to generate static electricity. In addition, the antistatic ability of LEDs of different quality grades is different, and the antistatic ability of LED underwater lights of 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-proof and sealing. This is especially true for LED underwater lights. Poor sealing problems will directly affect the service life of LED underwater lights.
1. Safety function
In landscape places, the choice of LED underwater lights takes personal safety as the first element. The LED underwater lights with a safety voltage of 12V must be used in accordance with the requirements of the national standard.
2. Lighting function
The lighting function mainly refers to the luminous brightness of the light source. It can choose different power LED underwater lights according to the illumination height and 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 occasion, the illuminating object and the atmosphere created.
3. Appearance and shell material
Although LED underwater lights are used underwater, they are not very conspicuous. But the appearance and material are related to the specific gravity of the lamp. If the specific gravity is too small, greater buoyancy will be produced, which will easily loosen the fixing screws of the LED underwater lamp, which will cause the lamp to float on the surface of the water, but too heavy to make the lamp stand 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 should be firm.
4. Economy
The economy of LED underwater lights refers to the sum of the one-time investment and operating costs of the lamps. Generally speaking, better quality LED underwater lights have higher prices, longer service life and lower operating costs. On the contrary, lower quality LED underwater lights are cheap, but they often cause blindness due to water leakage and electricity leakage. , Not only increased operating costs, some even affected the acceptance of the entire project.
