Abstract
A warmth-keeping structure of cold cathode lamp comprises a cold cathode lamp, a soft electric heating component and two insulating components. The soft electric heating component is wound around the surface of the cold cathode lamp. Two ends of the soft electric heating component are joined at two sides of the cold cathode lamp with the two insulating components slipped onto the joint portions, respectively. Through holes are formed on the insulating components so that different power sources can be provided for the soft electric heating component and the cold cathode lamp via conducting wires. The soft electric heating component can heat the cold cathode lamp in advance before the cold cathode lamp radiates to let the cold cathode lamp raise its ambient temperature in a few seconds and keep a fixed working temperature, hence stabilizing the brightness thereof and dissipating less power.
