The basic structure of the LED lamp is an electroluminescent semiconductor materials , placed on a wire rack, then sealed with epoxy resin around , protecting the inner core wire , so the seismic performance of the LED is good. LED is a rapid development of technology, is widely used for many general lighting applications , commonly referred to as solid State lighting. LED lighting is a typical application : indoor lighting ( for commercial , industrial and residential environment ), outdoor lighting ( street lights, parking lot lighting) and build Building, decorative lighting , initially, because of the light emitting diode capable of emitting the entire spectrum of color and are used for decorative lighting.

 LED has become an effective solution for architectural lighting . Compared to other lighting technologies,its superior performance makes led become General lighting market mainstream programs:

 1. Compared to other lighting technologies , LED has a longer service life. LED operating life of up to 50,000 hours, while the incandescent lamp life only 1,000 to 2,000 hours , compact fluorescent lamps (CFL) life of approximately 5,000 to 10,000 hours. Significant advantage showing LED is ideal for those who need to get into a larger human cost of replacement lamps for commercial and industrial applications.

2. Energy efficiency higher than incandescent and halogen lamps, equivalent to fluorescent lamps. In addition, LED 's efficiency is improving ; white LED (WLED) efficiency is expected to increase about 50% in the subsequent 3 to 4 years.

3. The smaller dimensions. LED lights Dimensions equivalent to the MR16 and GU10, while CFL unable to meet such applications.

4.The drive can be used to provide adequate brightness adjustment.The need to adjust the brightness of the application , fluorescent technically limitations. While traditional LED design also encountered a similar problem, but Walstar LED driver provides innovative solutions compatible with triac dimming and dimming design along.

5. With a strong directional lighting.Differently from other lighting technologies,LED is ideal for directional lighting applications, such as : small-angle reflector lamps.

6. When the temperature is lower with a higher efficiency. The efficiency of fluorescent lamps at low temperatures will drop . In contrast , LED is ideal for low temperature environments, such as:Refrigerator lights.

7. Can be easily changed luminous color. This advantage makes it an ideal choice for RGB LED buildings and scene lighting , it is possible to change the lights in real time according to specific requirements Light colors.

 In short , LED incandescent and fluorescent lamps do not have many advantages . Based on these advantages , designers continue to find suitable LED lighting solutions for More Applications.
