Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a backlight unit having a lamp fixing structure, and is particularly applied to an electronic product such as a liquid crystal display panel, a scanner, a facsimile, a commercial lamp box, and an art lighting means, and is easily detachable and assembled. The present invention relates to a backlight unit having a lamp fixing structure having characteristics such as easy replacement, easy replacement, and high stability.
[0002]
Now, cold cathode fluorescent lamps (abbreviated as CCFLs) are widely used in the near future because of their excellent features such as high brightness, high efficiency, low power consumption, long lighting life, small size, light weight, and low heat generation. In the backlight unit of electronic products such as liquid crystal display panel, scanner, facsimile, commercial lamp box, artistic lighting means, etc., the required light of each said electronic product is applied to the backlight unit. Quality can be generated.
[0003]
As shown in the conventional backlight unit shown in FIGS. 1, 2 and 2A, it includes a base 1 and a light emitting member 2, and the base 1 has two side walls 11, The side wall portion 11 has a perforation 111 and a flange 112 (see FIG. 2A) protruding outward, and the light emitting member 2 includes a lamp 21, an electric cord 23 connected to both ends of the lamp 21, and both ends of the lamp 21. 2A, and two soft covers 22 attached to the soft cover 22. A slit 221 as shown in FIG. 2A is retained at a corresponding inner end of each soft cover 22, and the lamp 21 is perforated between the side wall portions 11. 111, and the flanges 112 of the respective side walls 11 are inserted into the slits 211 of the respective soft covers 22, thereby securing the lamp 21 of the light emitting member 2. To. As the lamp 21, a cold cathode fluorescent lamp (CCFL) as described above can be used.
[0004]
Although the above-mentioned conventional backlight unit has a function of fixing the lamp, it still has many disadvantages as follows. That is,
First, as shown in FIGS. 2 and 2A, the flange 112 can be inserted into the slit 221 when the soft cover 22 of the light emitting member 2 is completely attached to both ends of the lamp 21 as shown in FIGS. Since the distance between the two soft covers 22 is smaller than the distance between the free ends of the two flanges 112, when the flanges 112 are inserted into the slits 221, inconvenience and trouble are caused.
[0005]
2. Unstable: the lamp 21 of the light emitting member 2 is fixed by simply inserting the two flanges 112 into the slits 221 in the two soft covers 22, and the size of the two slits 221 is easily adjusted. Due to various causes, the light is enlarged or loosened, so that the fixing quality is apt to be loosened, which may adversely affect the light quality required by the electronic device.
[0006]
3. Difficult to replace: If the lamp 21 breaks or breaks down after the light emitting member 2 is fixed as shown in FIG. 2, two soft covers 22 are already attached to both ends of the lamp 21. The light-emitting member 2 is difficult to remove, and the light-emitting member 2 is difficult to replace.
[0007]
[Problems to be solved by the invention]
In the present invention, in addition to having a structure for fixing a lamp in a backlight unit, the lamp fixing structure has an effect of being easily removed and mounted, and has a convenient, easy to replace, and after assembly, SUMMARY OF THE INVENTION It is a main object of the present invention to provide a backlight unit having a lamp fixing structure characterized by having an effect such as being extremely gentle.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a backlight unit including a base having both side walls and a light emitting member disposed on the base, wherein a notch is formed in each side wall of the base. And the light emitting member has a lamp, two electric cords connected to both ends of the lamp, two covers attached to both ends of the lamp, and a projection formed on the cover. And a groove formed in each of the protrusions, and the groove is formed so as to correspond to the notch, and the protrusion is fitted into the notch by the groove. And a backlight unit having the same.
[0009]
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0010]
[Embodiment of the invention]
As shown in FIGS. 3 to 5, the backlight unit having the lamp fixing structure according to the present invention includes a base 3 and a light emitting member 4. The side wall 31 has a notch 311.
[0011]
The light emitting member 4 includes a lamp 41, two electric cords 44 connected to both ends of the lamp 1, two covers 42 attached to both ends of the lamp 41, and a projection 43 formed on the cover 42. , A groove 431 formed in the protrusion 43, the groove 431 in each protrusion 43 corresponds to the notch 311, and the protrusion 43 is fitted into the notch 311 via the groove 431, The portion 43 is positioned in the notch 311, and the lamp 41 or the entire light-emitting member 4 is gently fixed between the side walls 31 of the base 3 by these treatments.
[0012]
As shown in FIGS. 4 and 5, each of the protrusions 43 is fitted into the notch 311 of the side wall 31 of the base via the groove 431, and a sliding fitting effect generated between the groove 431 and the notch 311 ( In the state of tight fitting, the "sliding-in effect" produces not only the effect of favorable stability and the effect of favorable positioning of the present invention, but also the effect of easily replacing the light emitting member 4.
[0013]
Among them, columnar objects can be adopted as the cover 42, and the convex portions 43 of the cover 42 are formed in a rectangular block shape or in a protruding annular shape arranged and arranged in a ring shape on the cover 42, and the notch 311 is also formed in a rectangular notch. In addition, the inner diameter of the notch 311 is formed to be smaller than the outer diameter of the convex part 43, and the convex part 43 can be directly and conveniently fitted into the notch 311 via the groove part 431 by these measures.
[0014]
The lamp 41 used as the light emitting member 4 of the present invention is a cold cathode fluorescent lamp (CCFL) having excellent features such as high brightness, high efficiency, low power consumption, long operating life, small size, light weight and low heat generation. Alternatively, a hot cathode fluorescent lamp or another type of lamp may be employed, and the lamp 41 may be formed in a straight tube shape, or may be a U-shaped or other shape. The backlight unit according to the present invention can be applied to electronic products such as a liquid crystal display panel, a scanner, a facsimile, a commercial lamp box, and an art lighting means.
[0015]
[Effect of the invention]
Since the present invention has the above configuration, it has at least the following excellent points. 1. Easy to remove and attach: the present invention can be directly fitted into the notch 311 of the base 3 by using the protrusion 43 having the groove 431, and the groove 431 and the notch 311 Regardless of the case of attachment or removal due to the "slipping fit effect" between them, there is an effect that all can be easily and conveniently executed.
2. The light-emitting member 4 is extremely stable after assembly: the light-emitting member 4 of the present invention is tightly fitted into the notch 311 by the groove 431 of the projection 43, and the gap between the groove 431 and the notch 311. It can be set to have an excellent stability by aiming for the purpose of less likely to be loosened by the “sliding-in effect”.
Third, it is advantageous for replacement: the present invention has the effect described in the above point 1, and thus has an effect that the light emitting member 4 can be easily replaced.
