High current LED, also known as high power LED, refers to a type of LED with a luminous flux of more than 100 lumens and a drive current of more than 350 mA. In recent years, with the continuous development of LED technology and the increasing demand for high brightness and energy-saving lighting, high current LED has become an important research direction in the field of LED industry. This article will introduce the high current LED industry, including its definition, development history, application fields, and future prospects.

Definition and Classification of High Current LED

High current LED is a kind of LED with high luminous flux and high drive current. According to the drive current, high current LED can be divided into three types: high power LED, super high power LED, and ultra-high power LED. High power LED has a drive current of 350 mA-1 A; super high power LED has a drive current of 1-10 A; ultra-high power LED has a drive current of more than 10 A.

Development History of High Current LED

The development of high current LED can be traced back to the 1990s. At that time, with the continuous improvement of LED technology, the luminous efficiency and light quality of LED gradually reached the level of traditional lighting. However, due to the limitations of driving current, the luminous flux of LED was still relatively low. In order to meet the needs of high brightness and energy-saving lighting, high current LED technology was born.

In the early 2000s, the high current LED technology was mainly developed in Japan, South Korea and the United States. At this stage, the main research direction was to improve the luminous efficiency and lifespan of high current LED. In the late 2000s, with the rapid development of semiconductor materials and manufacturing technology, the luminous efficiency and lifespan of high current LED were greatly improved, and the application fields of high current LED were further expanded.

Application Fields of High Current LED

High current LED has a wide range of application fields, mainly including the following aspects:

1. General lighting: High current LED can be used for street lighting, indoor lighting, commercial lighting, and other fields. Compared with traditional lighting, high current LED has high luminous efficiency, long lifespan, and low energy consumption, which can save a lot of energy and reduce carbon emissions.

2. Outdoor display: High current LED is used in outdoor advertising screens, information screens, and other fields. It has the advantages of high brightness, long lifespan, and wide viewing angle, which can meet the needs of various outdoor display applications.

3. Special lighting: High current LED is also used in stage lighting, car lighting, and other special lighting fields. It can provide high brightness and high color purity lighting effects, which is widely used in various occasions.

Market Analysis of High Current LED

At present, the high current LED market is growing rapidly. According to the data released by the market research report, the global high current LED market size will reach $XX billion in 2025, with a compound annual growth rate of 15%.

From the regional perspective, the high current LED market in China has the largest scale and the fastest growth rate. This is mainly due to the strong policy support and the rapid development of the domestic LED industry. In addition, the high current LED market in Europe and the United States is also developing rapidly, driven by the continuous improvement of consumer demand and the expansion of application fields.

Future Prospects of High Current LED

In the future, with the continuous development of LED technology and the continuous expansion of application fields, the high current LED industry will have the following prospects:

1. Higher luminous efficiency and longer lifespan: With the continuous optimization of LED materials and manufacturing processes, the luminous efficiency and lifespan of high current LED will be further improved, which will greatly reduce the cost of lighting applications.

2. More application fields: As the application technology of high current LED continues to improve, its application fields will continue to expand, such as intelligent lighting, medical lighting, and other fields.

3. Green and low-carbon development: High current LED has high luminous efficiency and low energy consumption, which is in line with the green and low-carbon development concept. In the future, high current LED will become an important force for promoting the development of green lighting.

In conclusion, high current LED has become an important research direction in the field of LED industry. With the continuous development of technology and the expansion of application fields, high current LED will play a more important role in the future lighting market.
