Embodiment Construction

[0035] The invention provides a cold cathode fluorescent lamp system with low-voltage grounding. The low-voltage electrode end of the lamp tube and the back plate are jointly grounded by the conductive ring of the conductive component, so that the current flowing through the lamp tube is balanced, so as to improve the performance of the backlight. overall luminous efficiency. And the simplified design of the conductive ring of the conductive component increases the convenience of assembly. The CCFL system of the present invention is suitable for backlight modules of liquid crystal displays (LCDs) and LCD TVs, or for display devices with backlight modules.

[0036] refer to Figure 3A and Figure 3B , which respectively show the top view and the side view of the CCFL module according to the first embodiment of the present invention. The CCFL module 300 mainly includes a lamp tube 302 , a first insulating component 304 and a conductive component 306 . The lamp tube 302 has a...

Abstract

The invention relates to a cold cathode fluorescent lamp system with low-voltage connected to the ground, wherein the invention comprises: a back plate, several tubes, several first insulated elements and several conductive elements, wherein each tube has the first electrode end, the second electrode end, and the first and second wires extending from the first and second electrode ends; the first insulated elements are arranged on the back plate, while each one has the first contain area and combined with the first wire; the first contain area is used to contain the first wire; each conductive element is relative to each tube to combine the first wire of tube; said conductive elements have one conductive ring electrically connected to the first wire; and the conductive ring is electrically connected to the back plate.

Description

technical field [0001] The present invention relates to a lamp tube structure, in particular to a cold cathode fluorescent lamp system with low voltage grounding, which is used in a backlight module of a liquid crystal display (Liquid Crystal Display, LCD). Background technique [0002] Liquid crystal displays are generally classified into transmissive liquid crystal displays, reflective liquid crystal displays, and semi-transmissive / semi-reflective liquid crystal displays. The transmissive liquid crystal displays are provided with a backlight module. The light sources used in the backlight module can be roughly divided into cold cathode fluorescent lamps (Cold Cathode Fluorescent Lamp, CCFL), hot cathode fluorescent lamps, light emitting diodes or other electroluminescent components (ElectroLuminescent Device, EL device), the current mainstream is cold cathode fluorescent lamps (CCFL ). [0003] The traditional backlight module is activated by the high voltage of the exter...
