In the past two years, the capacity of led lamps installed in the United States has increased 10-fold, from 4.5 million in 2010 to 49 million in 2012. This has resulted in an estimated annual savings of 675 million dollars in terms of the cost of energy. The latest report from the United States Department of Energy (united states department of energy, doe) states that this increase can be attributed to the fact that the number of led lamps installed in the United States was released. By the year 2030, it is anticipated that led lighting will account for 75% of total lighting sales; the energy saved may be utilized to power 26 million homes throughout the United States. • energy minister ernest moniz recently stated that the department of energy would finance five industrial research and development initiatives to promote efficient lighting solutions. This announcement was made by ernest moniz. It has been estimated that the luminous efficiency of led lighting products has reached 6-7 times greater than that of conventional lighting, which may be up to 25 times. doe intends to make an investment of ten million United States dollars in order to assist activities relating to the firm that are involved in research and development. According to moniz, funding research and development activities related to industry through energy efficient lighting will save consumers more energy and create more employment opportunities. This is an example of the win-win economic role that is brought about by research and development related to energy efficiency. Despite the fact that the costs of the replacement cycle are very appealing, the initial installation of led and oled lighting can be quite expensive. As a result, the Department of Energy (doe) is hoping that funding will contribute to a significant reduction in the costs associated with the production equipment, all the while maintaining lighting quality and performance. We can see that the energy saving advantage of led lighting has been realized, and the United States has been gradually replacing traditional lighting with led lighting. At the present time, led outdoor lighting such as led flood light, led tunnel lights, and led street light has gradually occupied dominance of commercial lighting and decorative lighting. On the other hand, for led indoor lighting such as led tubes, we need to increase the strength to popularity led bulbs.

Lead lighting is a professional led lighting manufacture that specializes in producing indoor and outdoor lighting. Dedicated research and development teams are increasing their efforts to improve technology so that the price of led lighting and its applicability are much closer to our lives.
