Research Status of LED Flood Light Integrated Package

Compared with traditional light sources, LED has such advantages as high luminous efficiency, energy saving and environmental protection, short response time, safety and reliability, etc., which have attracted people's attention since its invention. In recent years, LED flood lights has been more widely used, recognized by the industry the main direction of development, with great potential. With people's concerns about the global energy shortage intensified, the prospect of LED has attracted much attention. Now all countries in the world have formulated their own plans for LED development. Our "12th Five-Year Plan" has also clearly described the LED development goals and is listed as a key energy-saving project during the 12th Five-Year Plan. Emerging industries in the energy-saving environmental protection industries and new materials industries.

Currently, there are two ways to achieve high-power LED flood lighting: First, single high-power LED chip package, and second, multi-chip integrated package. For the former, with the development of the chip technology, the size is increased and the quality is improved, the high-power LED can be driven by a large current, but at the same time, the chip size is limited, and the latter has greater flexibility and development potential , According to different illumination to change the number of chips, while it has a high cost, making LED integrated package LED packaging become one of the mainstream.

A high school football field can be lighted for approxi- mately $200,000. This includes lighting levels of 30 foot- candles and assumes that power source is adequate and within 100 feet of one of the four poles. Costs could range up to $400,000 depending upon the field's location and specifications. Razorlux’s selection of football field lights and mounting adapters contains all that a small to mid-sized field requires to solve the problems of shadow and glare. Inadequate football field lights can lead to serious injury in either case, as shadow makes it hard for players to navigate the field, and glare can blind the eyes in moments of intense play.  Add to that the fact that most of the football fields we light are for children in pee wee and little leagues, or for junior high and high school teams, and the requirements for safety become even more paramount when we consider that it is the safety of children— and the very reputation of the game as a sport that makes America great
