Abstract
The invention relates to a light source framework and a backlight module. The light source framework comprises a border, an edge strip and a reflector plate, wherein the edge strip is arranged on the border and provided with at least one positioning hole; the reflector plate comprises a first surface and a second surface; the first surface is an optical reflector surface, and the second surface is provided with at least one hook; and the hooks are matched with the positioning holes and used for fixing the reflector plate onto the edge strip. By adopting the invention, the production efficiency of the backlight module can be improved and the production cost is lowered.
Description
Technical field
The present invention is about a kind of light source framework and module backlight, particularly relevant for a kind of light source framework and module backlight that is applied to liquid crystal indicator.
Background technology
At present, since the demand that reduces cost, the frame side structure of liquid crystal indicator (LCD) down straight aphototropism mode set employing black and white dichroic materials embedded design more and more widely.See also Fig. 1 and Fig. 2, Fig. 1 is the schematic diagram of light source framework 10 of the prior art, and Fig. 2 is the schematic diagram of the reflector plate 12 among Fig. 1.Edge strip 11 agent structures on the frame 13 are black, and reflector plate 12 is a white, but reflection source improves light utilization.
In the prior art, embedded design how in the following ways: one, double-colored integrated injection molding, but mould and complex forming technology, equipment cost height; Two, reflector plate is partially submerged in the frame mould and irritates wrap molding, but molding cycle is long, and yield is lower; Three, utilize the ultrasonic welding machine welding again after the moulding respectively, but need purchase the ultrasonic welder in addition.
Summary of the invention
The present invention is directed to above-mentioned technical problem, utilizing grab to cooperate after the moulding respectively edge strip and the fixing assembling of reflector plate.
Light source framework provided by the invention comprises frame, edge strip and reflector plate.Edge strip is arranged on the frame, and edge strip has at least one locating hole.Reflector plate comprises first surface and second surface, and this first surface is the optical reflection face, and this second surface has at least one grab, and this grab cooperates with this locating hole, in order to this reflector plate is fixed on this edge strip.
According to light source framework of the present invention, the moulding respectively of edge strip and reflector plate.
According to light source framework of the present invention, be evenly distributed a plurality of grabs on the second surface of reflector plate, edge strip has a plurality of locating holes in the relevant position, and those grabs snap in those locating holes.
According to light source framework of the present invention, grab comprises guide surface and blocking surface.
According to light source framework of the present invention, edge strip adopts black material, and reflector plate adopts white material.
Module backlight provided by the invention comprises light source and above-mentioned light source framework, and this light source is arranged in this light source framework.
Compared with prior art, the present invention has the following advantages:
One, former, mould and technology are simple;
Two, efficient height, molding cycle is short;
Three, compare with the ultrasonic burning-on method, adopt moulding respectively, but utilize grab to snap in mode, save ultrasonic welding machine, and packaging efficiency is higher;
Four, because grab is a tight fit, do not take place so do not have the reflector plate obscission in the transportation, use also can not produce different sound because of vibration.

The specific embodiment
For making purpose of the present invention, structure, feature and function thereof there are further understanding, cooperate embodiment to be described in detail as follows now.
Light source framework provided by the invention can be applied to the module backlight in the liquid crystal indicator, and this module backlight also comprises light source, and as fluorescent tube or led light source, this light source is arranged in this light source framework.
See also Fig. 3 and Fig. 4, Fig. 3 is the schematic diagram of light source framework 30 of the present invention, and Fig. 4 is the schematic diagram of the reflector plate 32 among Fig. 3.Light source framework 30 comprises frame (figure does not show), edge strip 31 and reflector plate 32 (please in conjunction with referring to Fig. 4, being blocked by edge strip 31) in Fig. 3.Edge strip 31 is arranged on the frame, and edge strip 31 has at least one locating hole 311.Reflector plate 32 comprises first surface 323 and second surface 324, and first surface 323 is the optical reflection face, and second surface 324 has at least one grab 321, and grab 321 cooperates with locating hole 311, in order to reflector plate 32 is fixed on the edge strip 31.
In one embodiment, edge strip 31 and reflector plate 32 moulding respectively.Be evenly distributed a plurality of grabs 321 on the second surface 324 of reflector plate 32, edge strip 31 has a plurality of locating holes 311 in the relevant position, and those grabs 321 snap in those locating holes 311.The quantity of grab 321 and locating hole 311 decides according to the size of reflector plate.In actual applications, edge strip 31 can adopt black material, and reflector plate 32 can adopt white material.
Please continue referring to Fig. 5, Fig. 5 is the structure enlarged drawing of the grab 321 among Fig. 4.Grab 321 comprises guide surface 3211 and blocking surface 3212, and Portable hook 321 inserts locating holes 311, and really with reflector plate 32 secure fixation on edge strip 31.
Grab 321 is the tight fit structure with locating hole 311, gets final product among directly reflector plate 32 being snapped in black edge strip 31 during assembling.
Compared with prior art, the present invention has the following advantages:
One, compare with the integrated injection molding method, former of the present invention, mould and technology are simple;
Two, compare with irritating the wrap molding method, efficient height of the present invention, molding cycle is short;
Three, compare with the ultrasonic burning-on method, the present invention utilizes grab to snap in mode, save ultrasonic welding machine, and packaging efficiency is higher;
Four, because grab is a tight fit, do not take place so do not have the reflector plate obscission in the transportation, use also can not produce different sound because of vibration.
The present invention is described by above-mentioned related embodiment, yet the foregoing description is only for implementing example of the present invention.Must be pointed out that the embodiment that has disclosed does not limit the scope of the invention.On the contrary, change of being done and retouching without departing from the spirit and scope of the present invention all belongs to scope of patent protection of the present invention.
