the commercial fishing industry is a demanding and dangerous field where the stakes are as high as rewards. Often working around the clock and deal with some of the worst weather conditions, commercial fishermen are familiar with the importance of having reliable equipment that can withstand the most abusive environments and continue to function without fault. With operations often take place in the night of fishing, the lighting is one of the teams that play a fundamental role in the security and productivity that can not be compromised on.
commercial fishing vessels generally use HID lighting systems in the shape of high-pressure sodium lamps in their work covers. Powerful and efficient, these lighting systems have provided an appropriate way if only the lighting which has been the standard for many years. Since these vessels are far offshore for long periods and must rely on independent sources of energy, energy efficiency and are key factors in determining the type of lighting to be used and to date systems, HPS have been the most practical.
two of the largest problems with HPS lighting in commercial fishing vessels have been very poor quality of light and moisture sensitivity. The light produced by an HPS lamp has a color other than orange color which produces poor in contrast and colour reproduction, reduction of visual acuity for those on the deck. HPS bulbs also run very hot, and any exposure to moisture while it is running can cause a light bulb to shatter or explode even violently and given the fact that these ships are exposed to some of the most humid marine conditions possible, everything happens too often. Despite all this, HPS systems have remained popular because of the long service life of the lamps and their very high luminous efficiency on the order of 120 lumens per watt. Less energy consumed by the lighting, the less fuel that is burned during them operations, improve the amount of time of a ship can remain in the sea pulling in them catches and reducing them costs associated with the fuel.
modern lighting technologies however change all this and offers some advantages that many commercial fishing operators are already capitalizing on. In particular, LED lighting systems have come to the fore that offer to provide durability and efficiency you need a fishing boat and not only this, but provide much better performance that the old HPS systems are replacing. For what this is going to look at some statistics with respect to the two types of lighting and how they stacked against each other.
lumens per watt production by HPS systems stockings 120 lumens per watt and is one of the most efficient ways of lighting available.
color temperature range of around 200 HPS Kelvin, put under incandescent light bulbs and resulting in a distinctive reddish orange color light output. HPS does colors, has poor contrasting qualities, and is usually used in applications where these qualities are not considered very important as the street and parking lot lighting applications.
life of the bulb lamps HPS average 20-40, 000 hours of useful life and are among the longest lived light sources available. However, HPS lamps are prone to a phenomenon known as “bicycle” where the age of the lamp, is made more difficult for ballast to maintain a high enough voltage to keep the lamp lit. Finally the voltage necessary to maintain the focus on exceeds the maximum capacity of ballasts and light bulb goes off. Once the lamp cools down less voltage is needed to turn it on and turn on the lamp back. This cycle continues until the fault lamp fully.
light bulbs HPS are very fragile as glass and are converted into very hot while in operation. As a result, they need comprehensive protection in the form of resistant covers, sealing joint and extensive of mounting to survive the harsh conditions of the marine environment of vibration absorption. As little as a single drop of water in contact with a hot HPS bulb is enough to cause it to fail explosively. Because of this, HPS lighting systems require frequent maintenance and inspection to prevent failures.
of LEDs-LED illumination of an average of 60 to 100 lumens per watt and is tied with fluorescent lighting for second place in the category of efficiency.
color lights temperature varies depending on the configuration and can establish a specific parameter. LEDs are available in 2700K, 4500K, 5000K, 6000K and color temperatures. LEDs for commercial fishing applications are typically in the range of 4500K to 6000K and as a result produce a very strong white light. In addition, LEDs provide good contrast and good color rendering, making them very suitable for applications where high visual acuity is important.
hours 50,000 + average life of LED lamp, and many accessories are available that you can reach 100,000 hours of life. In addition, as the LEDs age they do not experience significant changes in the operation. LED simply grow dimmer with time, and most manufacturers consider LEDs have reached the end of its useful life when they fall to 70% of its original production of lumen.
the LEDs are a form of solid-state lighting which is highly durable and versatile. They don’t have any glass they cannot break and don’t stay hot and thus are not so prone to the bankruptcy of exposure to small amounts of water. LEDs are highly resistant to damage is shock and vibration, which makes them ideal for applications where rough handling and abusive conditions.
LEDs offer to operators of commercial fishing, an alternative to lighting that can provide highly efficient performance coupled with much better quality light HPS systems. The light produced is whiter and stronger with better contrast and colour reproduction, which in turn helps with visual acuity during the performance of complex tasks. LED lamps ship are also much more durable than HID systems and are able to withstand the rough handling that could cause premature failure of a HPS lamp.
in general, commercial fishing operators speaking can improve safety and productivity in their housings without compromising the effectiveness of the lighting. More reliable, better performance and more durable, more lights boat represent a step up old systems HPS style that is hard to beat.
