Today i want to have a further researching which makes me understand products deeply. What is LED, what is made of LED, what are LED characters? LED full name is Light Emitting Diode. LED is a kind of diode which transfers electric energy to luminous energy. LED is so different basic theory from traditional lights. Obviously, LED is working much more time, more luminous efficacy and lower power cost. Our LED lamp housing is normally made of aluminum which is the best cost performance. In the LED industry, luminous flux(lm), luminous intensity(cd), luminous(cd/m2) and color temperature(K) is among the standards to measure LED lamp.
The Color Temperature shows illuminant photochromic measurement and its unit is K(Kelvin). The white range is divided to three parts: warm white, neutral white and cold white. The warm white always spread <3300K, the neutral white between 3000--5000K and the cold white over 5000K. Core-lead supplies all these three kinds of LED lights. The China scenery is normally 8000k--9500k. Core-lead does 3000k, 4000k and 6000k mostly. According to Chinese Fengshui, warm white is the best choice for home lightings. 3000k LED lights could be a good option. When you are walking into your room, the light make you feel so warm. Every member of your family will feel so peaceful and enjoy the family life. Whereas some European customer prefer 4000K which is less warm but gives more brightness. 6000K would be more preferred in offices, schools or factories where higher luminous flux is required.
