Description
Technical field
The invention provides a kind of conductive module of lamp tube and manufacture method thereof; More specifically, the present invention is about a kind of liquid crystal display backlight module that uses this conductive module of lamp tube.
Background technology
Because the liquid crystal itself in the LCD is tool emitting characteristics voluntarily not, thereby for reaching display effect, must provide a backlight module to give LCD, its function is to provide the light source that briliancy is abundant and be evenly distributed to LCD.
Generally speaking, backlight module is made of basic modules such as light source, framework and a plurality of blooming pieces.The light source of backlight module can be light-emitting diode (1ight emitting diode, LED), thermal cathode fluorescent tube (hot cathode fluorescent lamp, HCFL), cathode fluorescent tube (cold cathodefluorescent lamp, CCFL), plane fluorescent tube and external electrode fluorescent lamp pipe (external electrodefluorescent lamp, EEFL).
Fig. 1 is the structural representation of traditional backlight module.Backlight module 100 comprises a plurality of fluorescent tubes 111, one first framework 170, two lamp tube fixing piece 120,130 and is arranged at other blooming piece (not shown) on those fluorescent tubes.Respectively this fluorescent tube 111 is made of a body (tube) 111a, first electrode (first electrode) 111b and second electrode (first electrode) 111c, the first conductive electrode 111b and the second electrode 111c are arranged at the two ends of body 111a outside respectively, and mercury (Hg), phosphor powder (phosphor) and inert gas (inert gas, not icon) filling are in body 111a.
Respectively the group mode of this fluorescent tube is pressed into first electrode (first electrode) 111b and second electrode (second electrode) 111c in corresponding two lamp tube fixation assemblies 120,130.Wherein, those lamp tube fixing piece 120,130 comprise a plurality of fluorescent tube folders 122.Respectively this fluorescent tube presss from both sides 122, in order to hold fixing respectively first electrode of this fluorescent tube 111 (first electrode) 111b or second electrode (firstelectrode) 111c, this lamp tube fixation assembly 120 respectively, 130 are connected to the power source supply end (not shown) again, in order to provide power supply to respectively first electrode of this fluorescent tube 111 (first electrode) 111b and second electrode (second electrode) 111c.In addition, respectively this fluorescent tube folder 122 comprises a base 121 and a plurality of conjugate foramen 124, and this base 121 sees through on the hole 175 of accommodation section 173,174 that those conjugate foramens 124 are fixed in this first framework 170.
Yet, because respectively this fluorescent tube folder 122 is the purpose of differentiate electricity, all by the metal material made, and its profile is because of being subject to the fabrication schedule of this metal forming, make that respectively this fluorescent tube folder 122 is not to possess perfect out of roundness, so only be discontinuous point-to-point the contact in fact with first electrode (first electrode) 111b and second electrode (secondelectrode) 111c, and can't reach comprehensive face contact, not only conductive effect is had a greatly reduced quality, and discontinuous contact conduction, easily cause to be similar to point discharge phenomenon, use for a long time this contact point oxidation or deterioration take place easily, thereby cause the rapid deterioration of conductivity.
Moreover, if respectively the clamping elasticity of this fluorescent tube folder 122 is if design is bad, it is excessive and damage fluorescent tube to cause fluorescent tube to press from both sides 122 chucking powers, if behind maintain and replace fluorescent tube repeatedly, easier of the 122 frequent foldings of fluorescent tube folder, and make metal generation fatigue and cause fluorescent tube to press from both sides 122 permanent deformations, and then can't effectively conduct electricity; Consider that by cost benefit this fluorescent tube folder 122 needs to design in response to different products, thus need to a certain degree mould development and manufacturing expense, extremely uneconomical.
Summary of the invention
Purpose of the present invention mainly is to provide a kind of conductive module of lamp tube, is incorporated into the tension force that groove produced of lamp tube securing holder by conductive strips elasticity, to reach the purpose that can contact the conducting end of fluorescent tube fully.
Secondary objective of the present invention is to provide a kind of conductive module of lamp tube, be incorporated into the tension force that groove produced of lamp tube securing holder by conductive strips elasticity, whole conductive module of lamp tube can be reused, and do not have the problem of permanent deformation, and the cost that does not need extra fluorescent tube folder to design and develop.
Another object of the present invention is to provide a kind of backlight module, by comprising above-mentioned conductive module of lamp tube, makes the luminous efficacy of whole backlight module have the market competitiveness more.
