What is the advantage and application of LED technology challenge of LED in general lighting.

LED has highly efficient and durable advantage. These advantages enable us to achieve energy conservation, save money, make our costs under control and prolong the service life of the lamp. Because of the light radiation range of LED is a fixed arc, are not caused by the absorption of light of the lighting device loss or because of the light radiation angle at which light pollution from all sides. On the other hand, when LED is used in the lighting industry, to the fixed arc its radiation angle challenges. Lighting design using LED as the light source can ensure that the light in the irradiation range is the mean of the distribution.
