Cold cathode fluorescent lamp

摘要

A light transmitting container is used to house a cold cathode fluorescent lamp (CCFL) to reduce heat loss and to increase the luminous efficiency of the lamp. An electrical connector configuration is connected to an electrode of the lamp and adapted to be electrically and mechanically connected to a conventional electrical socket. A driver circuit in the container converts 50 or 60 Hz power to the high frequency power suitable for operating the CCFL. At least one of the electrodes of the CCFL is outside of the container to facilitate heat dissipation. A CCFL having an elongated tube portion and enlarged portions for housing larger electrodes is proposed to enhance the longevity and brightness of the CCFL. Larger electrodes are used to generate more electrons in the CCFL, thereby generating more light. Larger electrodes also reduces the temperature of the tube material of the CCFL to enhance the lifetime of the device.
