led seet light system reliability, durability, performance index part of the adaptation to the environment, the general led lighting product design and were not taking into account the dust protection system, outdoor lighting must completely prevent the road with sand dust storm, gelatinous suspension, gravity dust accumulation on the cooling sucture, to avoid overheating of the led caused problems.
neon signage such savings may greatly increase, because the led lighting system does not need any warming period, you can "instant-on" work, so in a very short period of time to reach maximum intensity. by these lights off when not needed to, or use motion conol sensors in order to avoid these lights work 24 hours a day, this plant can also save a lot more energy. figure 3: a high brightness white led lamp with high pressure sodium lighting refinery is another major advantage of the quality of light output. as can be seen in figure 3, left part of the plant is led lighting, led full-specum white light, and high-pressure sodium lamp (right side) compared, in which light is easier to see, and high pressure sodium light from almost all regions in the chromatography of the orange, which is very difficult to distinguish colors. in the refinery, which in particular is hard for me to use the naked eye because the distinction between water vapor and smoke caused by fire is a very painful thing.
neon sign to be able to accurately identify the wire color and color im is very important (even in dim light conditions). finally, the white led with 10 million hours of working life, working 24 hours a day, will continue to use more than 11 years, compared with high-pressure sodium lamps need to be replaced every year or two. high pressure sodium lighting and compared to the current, which further reduces the overall long-term high-brightness led costs. this white led lighting applications in the summary of indusial / residential area of general lighting has led to an unprecedented acceleration of large current led driver ic for many of the specific performance requirements. from oriented refinery, power plants and other harmful indusial applications of high power external lighting to the internal moving projection lighting, there are many indusial applications.
