摘要
Abstract
In this paper,the COB(Chip On Board) packaging technology is adopted in LED products to meet the requirements of high efficiency and low power dissipation.The optical features of LEDs are analyzed first.Subsequently,different packaging technology and materials are introduced to make a comparison between each other's effects on the flux,luminous efficiency and color temperature.Finally,the COB packaging technology is presented.After the introduction of its structure,advantages and practical utility,experiments are conducted.The experimental results show that the COB packaging not only has the capability of protecting the LED chips,but improves the efficiency and achieves specific optical distribution.Consequently,the proposed packaging technique achieves an increase on the luminous efficiency and adjusting of color temperature.关键词
