For the semiconductor lights, people concern so much about the efficiency and lumen maintenance. For instance, if the efficiency of single tube is less than 80lm/W, it will not be used for a light. The LED light which meets the criteria had also broken after using a short time, therefore, the service life of the light is still the major concern of people. Actually, both the efficiency and lumen maintenance have had got a radical transmission in the recent years. The electric source and controlled circuit become the main problems of the device, meanwhile, the laser diode and supporting policies of semiconductor lighting also need more attention.
According to statistics, seventy percent of LED light malfunctions are caused by the electric source, and twenty percent of malfunctions are caused by the line and construction problem. Only ten percent of malfunctions are related to the quality of the light. Choosing the proper electric source management is vital for energy saving, such as the AC-DC drive. The supply unit efficiency of AC-DC drive can reach eighty five percent. If the constant integrated circuit is connected with the drive, the efficacy is only seventy seven percent.
Compared with the high pressure sodium lamp, the LED light can save fifty percent of energy because of its strong directivity. Other advantages of the LED light can be found out compared with the high pressure sodium lamp, for instance, the brightness can be controlled via the circuit; the light can be opened in a very short time. All these characteristics can be used up to improve the performance of light. Methods can be taken to save the energy more, for example, the brightness changes in accordance with the surroundings and the number of pedestrians.
The laser diode is a special form of LED, which has single frequency and concentration energy. The laser diode is widely applied in many fields, such as the communication, military, memory and medical care field. The landscape lighting, stage lighting and laser display are the main parts of laser diode. The development of the laser diode has been taken into the agenda of different countries; therefore, it must change the life of people so much. The related integrated circuit is Z02201.
