LED illuminating system

LED lights (Light Emitting Diodes) are an efficient and energy-saving solution for ship lighting. Due to their low energy consumption, long lifespan, and durability, they are widely used in various lighting scenarios of ships, such as cabins, decks, signal lights, and navigation lights. Compared with traditional incandescent and fluorescent lamps, marine LED lights have significant energy-saving effects and higher reliability.

Long lifespan: up to 100k hours, 80% energy-saving compared to traditional halogen lamps. Durability: low maintenance costs,

working principle

1. DC electric drive

-Low voltage drive: LED lights are typically driven by direct current, which makes them highly efficient in energy conversion. Compared to traditional halogen lamps, LEDs do not rely on heating or gas discharge to emit light, but directly convert electrical energy into light energy, avoiding additional heat generation.

2. High luminous efficiency

-Directional illumination: LED lights can emit light at a narrow angle, with strong directionality, unlike traditional light bulbs that diverge light, making it more efficient in providing illumination in narrow spaces on ships.

-Light efficiency conversion: The electro-optical conversion efficiency of LED is as high as 80% to 90%, which means that the vast majority of electrical energy is converted into light energy, with very little converted into heat.

3. Durability and reliability

-Long lifespan: LED lights typically have a lifespan of 50000 to 100000 hours, far exceeding traditional halogen lamps. This is particularly important for ships, as it is difficult to maintain lighting fixtures in marine environments. Long life lighting fixtures can significantly reduce maintenance frequency and costs.

-Seismic resistance: LED lights have no easily damaged filaments or glass shells, strong seismic resistance, and can cope with the bumps and impacts of ships in harsh sea conditions.

Energy saving effect

1. Reduce energy consumption

-Efficient electro-optical conversion: The light efficiency of LED lights can reach 80-150 lumens/watt, greatly improving energy efficiency. This means that for the same lighting demand, the energy consumption of LED lights is only 10% -20% of that of traditional lighting fixtures.

2. Reduce fuel consumption

-Auxiliary energy conservation: As the electrical energy on board ships is usually provided by generators, which generate electricity by burning fuel, reducing lighting electricity consumption directly lowers fuel consumption. Based on an 80% energy-saving rate for lighting, assuming a ship consumes 20000 kWh of electricity annually for lighting, adopting LED lights can reduce electricity demand by 16000 kWh.

-Indirect fuel savings: Each kilowatt hour of electricity reduction may result in approximately 0.25-0.3 liters of fuel savings, which means 4000-4800 liters of fuel can be saved annually, thereby reducing operating costs and environmental emissions.

3. Reduce cooling load

-Reduce heat generation: LED lights generate very little heat, and compared to traditional lighting fixtures, using LED lights can significantly reduce the heat load inside the ship. This also has an impact on the load of the ship's air conditioning system, reducing cooling demand and indirectly saving energy consumption.

4. Extend service life and reduce maintenance costs

-Long lifespan reduces maintenance requirements: LED lights have a lifespan dozens of times longer than traditional lighting fixtures, reducing the frequency of bulb replacement and maintenance, especially in the high difficulty environment of ships, which significantly reduces labor and downtime costs.

5. Reduce emissions

-Emission reduction effect: Due to the reduction of electricity consumption by LED lights, the decrease in fuel consumption directly reduces the emissions of carbon dioxide (CO ₂), nitrogen oxides (NOx), and sulfur oxides (SOx).

Marine LED lights provide a more efficient and environmentally friendly lighting solution for ship operations by significantly reducing energy consumption, fuel consumption, and maintenance costs.
