Characteristics of LED garden lamp LED underwater lamp

1, voltage: LED adopts low-voltage power supply, and the power supply voltage is between 6-24V, which varies according to different products, so it is a safer power supply than high-voltage power supply, especially suitable for public places.

2. Efficiency: Compared with incandescent lamps with the same light efficiency, the energy consumption is reduced by 80%.

3. Applicability: Each unit LED die is 3-5mm square, so it can be made into devices with various shapes, which is suitable for changing environments.

4. Stability: 654.38+100000 hours, and light attenuation is 50% of the initial value.

5. Response time: The response time of incandescent lamp is millisecond, and that of LED lamp is nanosecond.

6. Environmental pollution: no harmful metal mercury.

7. Color: The color can be changed by changing the current. Light-emitting diodes can easily adjust the energy band structure and band gap of materials through chemical modification to realize multi-color emission of red, yellow, green, blue and orange. For example, LED is red under small current, and it can turn orange in turn and green at last with the increase of current.

Matters needing attention in purchasing LED underwater lights 1. Safety function: in landscape places, personal safety is the primary factor in choosing LED underwater lights.

According to the requirements of national standards, the color shall be 12V safe voltage LED underwater lamp.

2. Lighting function: The lighting function mainly refers to the luminous brightness of the light source.

Different power LED underwater lights can be selected according to the lighting height and light projection area.

Another element of lighting function is the color of underwater lanterns, generally red, yellow, green, blue and white, which can be selected according to the application situation, irradiation object and created atmosphere.

3. Appearance and shell material: Although underwater lanterns are used underwater, they are not very eye-catching.

But the shape and material are related to the proportion of the lamp.

If the specific gravity is too small, it will produce greater buoyancy, which will easily loosen the fixing screws of underwater colored lights and make the lights float on the water. If it is too heavy, it will not support the lamp holder.

At the same time, due to long-term use in water, its shell material should have certain anti-corrosion function, and the surface paint layer should be firm.

4. Economy: The economy of underwater lamps refers to the sum of one-time investment and operation cost of lamps.

Generally speaking, high-quality underwater lamps have higher price, longer service life and lower operating cost. On the contrary, low-quality underwater lanterns are often blinded by water leakage, which not only increases the operating cost, but also affects the acceptance of the whole project.
