1, introduction
Our country's energy situation trend nervous energy shortage to energy consumption of large famous manufacturing tremendous impact. Manufacturing enterprises to go energy-saving road is the trend of The Times. Enterprise has a 20% above the potential of energy saving, due to a lack of energy saving reconstruction funds and energy-saving consulting services, heavy energy cost of enterprise cost greatly improved, not only makes the power supplies are tight, also have poluted our living environment.
In the factory, lighting energy consumption occupies a certain weight. In plant lighting of lamps and lanterns choosing, how to realize the energy conservation, the environmental protection on is an important topic of factory designers. Adopting new LED light-source based lightings, except for energy conservation and environmental protection outside, it also has long life, fast response time, light color pure concentrated light etc, in recent years, widely welcomed by customers.
2, the transformation principle
As is known to all, energy consumption mainly concentrated in the industry. Reports from related media reports, 2009 guangdong industrial users of the energy consumption of the terminal 63.9%, industry cuts energy consumption this "big head" when for energy conservation and consumption reduction in a heavy emphasis on generalizing applied energy-saving lighting products is the trend of The Times. In order to meet market niche, high-end users (factory, railway, hospitals, street lamp departments such as large again already should pay much attention to the energy saving lighting industries and fields) needs, LED lamps and lanterns for such users into lighting environment improvement, energy-saving efficiency to 50% profit returns.
3, project cases
In a large state-owned enterprise one of the workshop, for example: a workshop construction area of 4,000 square meters, plant height 13 meters, illume height limit of 10 meters and existing some brand high-efficiency 400W metal halide lamp 200 sets of each lamp light source cost is RMB 52 yuan, originally lamps and lanterns in the ground as 30 - illuminance is 50LUX, the existing problems: the luminous efficien low, intensity of illumination is insufficient, poor safety; High energy consumption, light failure fast, color rendering low; Voltage instability when cannot startup, replace frequently and big workload.
3.1 illuminant choice
On market at present high power LED light source comparison of well-known brands are: CREE, NICHIA, Lumileds OSRAM, supplier in Taiwan, in addition of crystal yuan, YiDiSen and domestic encapsulation giant, shenzhen WanRun, zhuhai ruifeng, lianchuang to wait also is applied more popular brands.
To ensure the stability of the products, we choose the most famous CREE illuminant.
3.2 power options
In building lighting design meets the standard "condition, use 200 lamp 100W British platinum LED lamp can satisfy mining lighting design requirements.
3.3 cost and benefit evaluation
As is known to all, compared with high-pressure sodium lamp or metal halide lamp for workshop lighting, LED lamp initial mining cost obviously higher than traditional lamps and lanterns many. However, due to LED source has the characteristics of high efficiency, plus made when lamps and lanterns, LED light-source directionality strong advantage easily manifested, LED lamps and lanterns than traditional of lamps and lanterns efficiency is much higher, so its energy-saving characteristics can be clearly reflected. The table below for the platinum 100WLED mining lamp and traditional high-efficiency 400W metal halide lamp investment benefit analysis.
