Guide: Luxury cruise ships sail on the surface of the water. They are exposed to high salinity, high humidity and high vibration for a long time. They often encounter bad weather with strong winds and waves, and have high requirements for the reliability and stability of lighting equipment.
Luxury cruise ships sail on the water surface and have long been in a high salinity, high humidity, high vibration environment. They often encounter bad weather with strong winds and waves, and have high requirements for the reliability and stability of lighting equipment. Luxury cruise lamps originally used traditional light sources such as halogen lamps, incandescent lamps, fluorescent lamps, high-pressure mercury lamps and high-pressure sodium lamps. These lamps have low luminous efficiency, short life, high energy consumption, large maintenance workload, and many mercury pollution and frequency. Problems such as flashing exist, so the replacement of luxury cruise lighting has become increasingly important.
As a marine lighting fixture, LED lights have the following obvious advantages:
First, high light efficiency, low power consumption, saving energy
LED single lamp power is generally 0.05-1W, which can meet different needs through clustering, and waste is very small. The LED is driven by DC, and the light source has high luminous efficiency and relatively low power consumption. Compared with the luminous intensity, the energy consumption is only 10% of the incandescent lamp and 50% of the fluorescent lamp. The use of LED lighting can save a lot of lighting energy.
Second, strong earthquake resistance, long service life
LED is small in size and light in weight. The outer casing is made of epoxy resin. It is not afraid of seawater corrosion and has strong seismic resistance. It not only protects the internal chip, but also has the ability to collect light and light. As long as it is designed for marine fixed structures, it is no longer necessary. The design of the extra explosion-proof lampshade is simpler and lighter in structure, and the service life of the light source is generally between 50,000 and 100,000 h.
Third, green, high security
LED luminaires convert AC power directly into DC power. The operating voltage is low, mostly 1.4-3V; the operating current is only 10mA, and the ultra-high brightness is only 1A.
LED does not contain harmful gases, and does not contain heavy metals such as lead and mercury. It does not need to be inflated, does not require a glass casing, has good impact resistance, good shock resistance and is not easily broken. There is no infrared and ultraviolet radiation in the spectrum, and good LED illumination can be used. There is no stroboscopic phenomenon; waste can be recycled, low heat, no pollution to the environment; no mosquitoes around the lamp body at night, so that the lighting environment is cleaner and more tidy, known as "green energy."
Fourth, high luminous efficiency, high efficiency of lamps
The luminous efficacy of incandescent and tungsten halogen lamps is 12-24 lm/W (lumens/watt), the luminous efficacy of fluorescent lamps is 50-80 lm/w, and the luminous efficacy of sodium lamps is 90-140 lm/W. Most of the power consumption becomes Heat loss. The LED light effect can be improved to 50-200 lm/W, and the light has good monochromaticity and narrow spectrum, and can directly emit colored visible light without filtering.
The traditional fluorescent lamp is 360°, and the opposite direction of illumination is useless. Generally, the efficiency of traditional fluorescent lamps is only 70%, while the illumination angle of LED lamps is usually 120°, which can be adjusted according to demand, and the luminous efficiency is higher than that of traditional lamps. .
Five, no noise, no radiation
Qualified LED luminaires have no noise and are more suitable for cockpits, chart rooms, workplaces that require a high concentration of attention, and the rest of the crew. Traditional luminaires use alternating current, so they produce 100~120Hz strobes. A better quality LED luminaire converts AC power directly into DC power, so there is no stroboscopic phenomenon and the radiation is very low.
Sixth, rich in color, providing a comfortable living environment for tourists and crew
Light of different color temperatures will give people a different feeling. The color temperature is below 3300K, and the light color is reddish to give a warm feeling. When the color temperature is 3000-6000K, there is a refreshing feeling. The LED's selectable color temperature range is 2000-9000K, which provides a very good lighting environment and rich lighting color for cruise ships.
