Abstract: A connecting unit for accommodating a wick of a cold cathode fluorescent lamp is disclosed. The connecting unit includes a substrate having a conductive layer disposed thereon, a v-shaped opening, and a c-shaped opening. The width of the front end of the v-shaped opening is greater than the diameter of the wick, and the width of the back end of the v-shaped opening is less than the diameter of the c-shaped opening and less than the diameter of the wick. The conductive layer is disposed on a surface of the c-shaped opening and the v-shaped opening.
