LED Lighting 'saves' American soldiers

According to the report, there is almost nothing more common than fluorescent lamps on US Navy ships. They are almost everywhere, including decks, emitting the familiar, sometimes flickering white light. As lighting devices installed at the head of each sailor's bed, they can make a buzzing sound large enough to make it difficult for people to sleep. However, if the new generation of light emitting diodes (LED) Light bulb manufacturers can get what they want, and classic fluorescent lamps will soon disappear, just like sound tubes and telegraph machines in engine rooms. Eric, president and Navy veteran of Energy Focus, a company specializing in LED technology. Hilliard said: The Navy has demand, not only to save more energy, but also to understand LED. They have been using very outdated technology T12 lighting ballast technology. They also have maintenance needs. T12 fluorescent lamp is a common model with a diameter of 1. 5 inch. Ballast is a device that limits current in fixed lighting devices. According to the report, the energy focus company found business opportunities. Hilliard said: from the company's point of view, this is a good opportunity for a small business. When (Market) When controlled by large companies, it is difficult to compete on a large scale. This is a niche market. Considering maritime safety, new LED products must be durable and simple. Hilliard explained: our idea at the time was to take out the existing bulb and put it in the LED bulb. The ballast and starter of the lighting device will identify whether it is a fluorescent bulb or an LED bulb. We must follow the existing specifications. There was no such thing at the time. So we must create this kind of light bulb and convince the navy of its safety. Energy Focus began to cooperate with the research projects Bureau of the Ministry of Defense and the Naval Ocean Systems Command to develop LED lighting devices and bulbs that meet the requirements of naval ships. The company has designed and manufactured four basic products: 2 feet LED lamps and bulbs of different sizes that can be installed in busy areas such as cargo holds, ammunition depots and freight elevators, explosion-proof bulbs that can be placed in munitions cabinets and gas turbines, as well as bedside lamps equipped with USB interfaces and other devices. The report said that the market demand is considerable. A typical Ali. The single-tube, double-tube and three-tube lighting devices of Burke-class destroyers require 281 bedside lamps, 201 large bulbs and 50 small bulbs, 19 explosion-proof bulbs and at least 3682 2 feet bulbs. The larger the ship is, the more bulbs are required. For example, cruisers need about 6000 2 feet lamps. Obstacles include the need to reinstall the device that holds the bulb and the bracket, but the company has manufactured a smart tube 2 feet bulb that can be placed in an existing lighting device. The report said that the price still needs to be discussed. The price of a T12 bulb in the Defense Logistics Bureau procurement system is about $4. The price of each 2 feet LED lamp sold by energy focus company to the Defense Logistics Bureau is 145 US dollars, plus the transportation cost of 13 US dollars, the cost of each lamp is 158 US dollars. However, the US Navy expects that for a destroyer with a service life of at least 35 years, the cost of installing LED lighting will be recovered within 10 years. The Naval Ocean Systems Command wrote in a statement: it is expected that there will be additional benefits of reduced maintenance and replacement costs. The Naval Ocean Systems Command wrote: reducing energy and fuel consumption and reducing maintenance and replacement costs are the main drivers for installing LED lights. The life of LED lamps is about 5 to 10 times longer than that of fluorescent lamps and incandescent lamps, and it can also save 50 to 80 energy. Dave, business development manager of energy focus. Bina said that since the approval of the batch of devices in September 2010, nearly 200 ships have installed at least some models of LED lighting devices and bulbs produced by energy focus. He said: We estimate that the life of LED bulbs on each ship is 10 years. The replacement frequency may be once every few decades. The report said that the Naval Ocean Systems command seems to be very satisfied. The command wrote in the statement: Installed in (Destroyer Preble and Chaffee) The LED lights on fully meet the standards, including impact and vibration performance. The LED lights installed on these ships have performed well since 2011 and meet all requirements. The new ship designated to be fully equipped with LED lighting is Paul, who is under construction at Ingels shipyard in pascagula, Mississippi. Destroyer Ignatius. The Naval Ocean Systems Command wrote that all Ali in the future. Burke-class destroyers will be equipped with LED lights. Stephen, chief engineer of the destroyer Preble, docked at Pearl Harbor. The captain said that improving LED lights is not always simple. However, he wrote in an email on August 25 ,(They)It is much brighter than fluorescent lamps. The life of LED lights is also longer, which helps to save money, but more importantly, it reduces the time spent manually replacing the whole ship lighting device.
