Calculation will be
10*60 parallel arrays 600mA/1A
7*3.4 series arrays 23.8V/25.4V
★LED quantity can be adjusted when it is needed
Apply the dimming system at the circuit
Reflector setting(Using mirrors and so on)
Outlet designing and scaling
Luminance examination(whether it is following industry standards)
LED panel, temperature distributions of heat sinks and of the surrounding air were properly assumed for the numerical heat transfer analysis.
As the results, surface area, the heat transfer coefficient, the heat performance, and optimum fin spacing of three different fins depend on their shapes.

led the discussion in class.
Our group agreed that we don’t have much time for everyone to share their ideas if the whole class becomes a group. Moreover, we observed from last discussion that the debate became concentrated to some students who were active. Consequently there were some other people who didn’t make many statements. To solve these problems, we’ve decided to divide students
우리의 실생활에 있어서 전기는 매우 유용하다. 만약 전기의 빛이 없으면 인간은 벌써 생존하지 못하고 죽었을 것이다. 만물이 생존하려면 물과 빛이 있어야 가능하기 때문이다. 현재 지구촌은 지구온난화로 인한 온실효과를 줄이기 위한 방편으로 백열전구 대신 LED조명을 선호하고 있다.
