LED lighting design

In today's world is a pursuit of efficiency but also attaches great importance to the concept of cost time. Especially in the development and utilization of energy. LED appears to cater to the needs of this era. From the performance of the LED light source, in the same brightness, its service life is 100 times longer than ordinary incandescent lamp and energy consumption is only about 1/10, the cost of daily maintenance is very low. Of course, the lighting effect of the LED is not inferior to the traditional lighting equipment. From the point of view of environmental protection, LED light source will not produce light pollution to the surrounding environment, is recognized as green lighting. Of course, it is not limited to these advantages, it is not without drawbacks, however, believe that with the development of lighting technology, its advantages will be developed more, shortcomings will be improved.

Lighting column this period will be introduced in Losangeles in the United States Vincent Thomas bridge for you, it is one of the world's few through the bridge to illuminate the LED, hope to get more information about the LED lighting cognition we can from it.

This seat is located in the Losangeles Harbour Bridge Vincent Thomas height of 365 feet; 185 feet away from the surface (about 35 storeys high). A total length of 6060 feet, wide (Road) of 52 feet.

Bridge on November 15, 1963 officially pass, which is based on the former state senator Vincent Thomas (1908-1980) named. It is in this person's implementation, and now, this bridge has become very important to the Losangeles harbour road.

In early 2000, due to the prohibition of the U. S. government released all unnecessary decorative lighting projects (including bridges) regulations, and coincides with the California encounter the problem of energy crisis, many lighting project was cancelled.

Most of the bridge lighting project, such as the Golden Gate Bridge of San Francisco is in the lighting on consuming a lot of energy. Therefore, at the time of lighting engineering planning, many supporters of the efforts of the state energy problems have become a bubble. However, the Vincent Thomas lighting Committee and its chief executive, Dominguez, did not give up the project.

Bridge lighting Committee CEO Dominguez said, in a period of time before, when the problem of energy crisis, they realized that LED might be the only effective choice.

Fortunately, today's world LED lighting one of the giants of LEDTronics, is located in California near torrance. It was not until the last few years or so that LED developed from a single miner's hat and the use of traffic lights to a variety of lighting applications. LED lamps have a strong advantage is very suitable for the bridge lighting project, that is "energy saving".

Each LED lamp is only 20 watts, but his light output is equivalent to a 150 watt incandescent lamp output. After solving the problem of energy conservation, the committee responsible for bridge lighting realized that they could provide all the energy needed for bridge lighting by using an appropriate 4.5 kW solar energy device. Some analysts said that if the use of lighting is the traditional type of light, the entire bridge covering the 160 LED lamps will require a minimum of 70KW solar system for energy.

The average life expectancy of these 5 mm diameter LED for 100000 hours, which is extremely effective reduces the maintenance cost of the project.
