How to detect the quality of LED light source

　　The most current public preferences LED lamps are made shell , light , electrical lamp composed of three parts . In light of these three components and appliances are among the most important , a good electrical light sources must be used with high quality in order to achieve the best lighting effects. So how good or bad the LED light source is detected ?

　　1 , See LED light flux, how much light can send its light ;

　　2, Measuring LED light source color temperature, color temperature that is emitted by the light source is the number of light emitted by the lamp is generally yellow and white points. In the professional field , yellow is 3000k less than white is 5000k , 3000k-5000k in between is the middle color ;

　　3, Observe the color LED lamps , light fixtures whether that is entirely correct illumination of the color of the object. The industry generally believe that sunlight can correctly reflect the true color of the object ;

　　4 , Determine the average life of LED lamps , for example, there are a number of sources, these sources generally light of the number of average life expectancy is the average lifespan of these products , pay attention to the average life expectancy at least a year and a half or more before they can ;

　　5, The light efficiency , high luminous efficiency lamps illuminated the same length of time to test LED lighting source of electricity used even less , so more high efficiency, more energy-saving.
