Description
Technical field
The utility model relates to a kind of back light unit with lamp tube fixing structure, particularly a kind of being applied in the electronic installations such as LCD, scanner, facsimile recorder, advertising lamp box or artistic lighting, and have " readily removable, group, easily change and the lamp tube fixing structure of effect such as higher stability " back light unit.
Background technology
Because advantage such as have brightness height, efficient height, power consumption is low, the life-span is long, volume is little, in light weight and thermal value is low, cathode fluorescent tube (Cold Cathode Fluorescent Lamp, be called for short: CCFL) be widely used at present making this back light unit can produce the needed light quality of above-mentioned various electronic installation in the back light unit of electronic installations such as LCD, scanner, facsimile recorder, advertising lamp box or artistic lighting.
Fig. 1 is the stereographic map of existing fluorescent tube fixture construction, and other has shown the sectional view and the partial enlarged drawing of existing fluorescent tube fixture construction at Fig. 2 A and Fig. 2 B.Wherein, existing back light unit comprises a pedestal 1 and an illuminated component 2, this pedestal 1 is provided with two sidewalls 11, each above-mentioned sidewall 11 is equipped with the lug 112 (shown in Fig. 2 B) of a perforation 111 and a relative evagination, 2 of this illuminated components comprise a fluorescent tube 21, be connected in two groups of electric wires 23 at these fluorescent tube 21 two ends and be socketed on two soft bodies 22 at these fluorescent tube 21 two ends, respectively this soft body 22 respectively remains with a slit 221 shown in Fig. 2 B relatively between the inner, described fluorescent tube 21 penetrates in this two side in 11 the perforation 111, and the lug 112 of this sidewall 11 respectively can be inserted in the slit 221 of this soft body 22 respectively, thereby fix the fluorescent tube 21 of this illuminated component 2.Wherein, fluorescent tube 21 promptly can be aforesaid cathode fluorescent tube.
Though above-mentioned existing back light unit has the function of fixed lamp tube, it also exists many shortcomings to have much room for improvement:
One, trouble is installed: shown in Fig. 2 A and Fig. 2 B, the soft body 22 of this illuminated component 2 must be inserted in fluorescent tube 21 two ends fully, described lug 112 is inserted in the slit 221, yet, the distance that this two soft body is 22 is but less than the distance between the free end of these two lugs 112, and this can cause difficulty when lug 112 is inserted slit 221.
Two, fixing built on the sand: the fluorescent tube 21 of this illuminated component 2 only relies on and two lugs 112 are inserted in the slit 221 of two soft bodies 22 and is fixed, yet owing to the size in these two slits 221 will enlarge even slack and undisciplined because of a variety of causes, and then cause the loosening of its stationary state, further can influence the desired light quality of aforementioned electronic.
Three, change difficulty: after this illuminated component 2 is decided together like that shown in Fig. 2 A, when fluorescent tube 21 damage or failure condition occur and must change the time, because two soft bodies 22 have adhered to the two ends of described fluorescent tube 21, thereby the utmost point is difficult to pull down this illuminated component 2, so it is just very difficult to change this illuminated component 2.
