It is reported that China's first luxury cruise ship is expected to be delivered by 2021. The luxury cruise ship is regarded as the top ship type product in the world's high-end marine equipment manufacturing industry. It is the only high-tech ship product that has not yet been overcome in China. Among them, LED marine light as a lighting device for cruise ships, its product quality and performance must also undergo rigorous tests.
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
The 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
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 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
The luminaire converts the alternating current directly into direct current. The working voltage is low, mostly 1.4-3V; the working current is only 10mA, and the ultra-high brightness is only 1A.
Contains no harmful gases, and does not contain heavy metals such as lead and mercury; does not require inflation, does not require a glass casing, has good impact resistance, good shock resistance, and is not easily broken; no infrared and ultraviolet radiation in the spectrum, better LED lighting can be done There is no stroboscopic phenomenon; waste can be recycled, low heat, no pollution to the environment; no mosquitoes around the lamp body at night, making the lighting environment cleaner and 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.
Shanghai Sansi is a high-tech enterprise specializing in the R&D and production of LED application products. Based on multi-disciplinary advantages, the independent patented LED marine light series from the perspectives of optics, electricity, structure and materials can not only meet the above LEDs. All the advantages of the luminaires enhance air convection and disperse heat dissipation to prevent the LED lamps from rapidly attenuating due to overheating. The smooth surface design prevents salt spray from invading and changes optical characteristics, prolonging service life and enhancing reliability.
For luxury cruise ships, decorative lamps and lighting fixtures with both functional and amusement features are more abundant and the number is multiplied, and electric energy consumption accounts for a larger proportion. The LED marine light series developed by Shanghai Sansi has made major technological breakthroughs in optics, structure, heat dissipation, protection and control, and the energy saving effect is very obvious.
Many products have obtained the “China Energy Conservation Product Certification Certificate†from China Quality Certification Center and entered the “Government Procurement List of Energy Saving Products†and the “National Key Energy Saving Low Carbon Technology Promotion Catalogue†of the National Development and Reform Commission.
Marine lighting, represented by LED signal lights, searchlights, downlights, ceiling lamps, etc., is equipped with suitable secondary optics for different environments, and the advantages of LEDs are fully realized, and an original integrated control system has been developed. It opened a new chapter in marine LED lighting solutions and was the first to pass the certification of China Classification Society.
The construction of domestic luxury cruise ships that are of great concern is a major systematic project. New products, new technologies, new materials and new processes of independent national brands should be adopted as much as possible.
Shanghai Sansi always insists on technological innovation and product innovation as the source of enterprise development. It has mastered a large number of core technologies in LED application products, and develops independent patent LED marine light series and small-pitch LED display series that meet the certification requirements of classification society. And the intelligent street lamp system, etc., reached the international advanced level, the product's technical indicators and market share are in the forefront, is the leading enterprise in the domestic and even international LED industry.
Shanghai Sansi will continue to strive to use the international leading LED marine light series, LED display series and original integrated control system on domestic luxury cruise ships, officially setting sail for the first real luxury cruise ship built in China. Contribute.
