Fig. 3 is the following partial schematic diagram of looking of a kind of light source module of one embodiment of the invention.Please refer to Fig. 3, the light source module 300 of present embodiment comprises power panel 210, light source 220a, light source 220b, pliability parallel conductor layout 240a, pliability parallel conductor layout 240b and backboard 230.In the present embodiment, backboard 230 has the back of the body surperficial S and a front surface (do not illustrate, i.e. another surface of backboard 230, it is positioned on the direction of incident paper), and wherein light source 220a, 220b are disposed on the front surface.On the practice, light source module 300 can be used as the backlight module in the display unit, and light source 220a, 220b can provide the display floater of display unit required light, and wherein light can be passed in the display floater with the direction of incident paper.
In the present embodiment, light source 220a, 220b for example are disposed on the front surface in two modes of growing limits of being close to display unit respectively.Therefore, light source module 300 can further be provided with LGP (not illustrating), so that line source that light source 220a, 220b are sent guiding is suitable area source.In a preferred embodiment, light source module 300 also can further be provided with blooming pieces (not illustrating) such as diffusion sheet, brightening piece, prismatic lens, to promote the luminous efficiency or the luminance uniformity of light source module 300.Yet the number of the light source in the light source module and configuration place thereof should be actual products and deciding, and the present invention also is not intended to restriction.
In the present embodiment, light source 220a and light source 220b can see through pliability parallel conductor layout 240a and pliability parallel conductor layout 240b respectively and be electrically connected to power panel 210.Because the arrangement space of display unit is limited, generally power panel 210 can be disposed on the surperficial S of the back of the body.As shown in Figure 3, the backboard 230 of present embodiment has holes 230H
1And holes 230H
2, holes 230H wherein
1, 230H
2Can run through surperficial S of the back of the body and front surface.Thus, the two ends of pliability parallel conductor layout 240a just can see through holes 230H
1To electrically connect power panel 210 and light source 220a respectively, the two ends of pliability parallel conductor layout 240b then can see through holes 230H
2To electrically connect power panel 210 and light source 220b respectively.
Specifically, the power panel 210 of present embodiment is made of body 212 and the connector 214a and the connector 214b that dispose on it, and wherein body 212 is between the S of the back of the body surface of connector 214a, 214b and backboard 230.On the practice, body 212 can further have at least one screw hole H
sAnd at least one screw A, so screw A can pass screw hole H
sSo that power panel 210 is fixed on the backboard 230.
In the present embodiment, pliability parallel conductor layout 240a has input 242a and output (does not illustrate, be positioned on the direction of incident paper), and pliability parallel conductor layout 240b also has input 242b and output (do not illustrate, be positioned on the direction of incident paper).With regard to this one side of the back of the body of backboard 230 surface S, pliability parallel conductor layout 240a electrically connects by input 242a and connector 214a, and pliability parallel conductor layout 240b is then by input 242b and connector 214b electric connection.On the other hand, pliability parallel conductor layout 240a can pass holes 230H
1And its output and light source 220a are electrically connected, pliability parallel conductor layout 240b then can pass holes 230H
2And its output and light source 220b are electrically connected.
More specifically, the body 212 of the power panel 210 of present embodiment has holes 212H
1And holes 212H
2In order to combining of power panel 210 and pliability parallel conductor layout 240a, 240b.Particularly, in a preferred embodiment, pliability parallel conductor layout 240a and pliability parallel conductor layout 240b can further pass holes 212H respectively
1With holes 212H
2And make its input 242a and input 242b electrically connect connector 214a and connector 214b respectively.Say that further pliability parallel conductor layout 240a and pliability parallel conductor layout 240b are passing the holes 230H of backboard 230 respectively
1With holes 230H
1After can be between backboard 230 and power panel 210, and then make progress from power panel 210 belows (direction of outgoing paper) passes the holes 212H of power panel 210 respectively
1With holes 212H
2, and input 242a, 242b are electrically connected with connector 214a, 214b respectively.
From the above, the pliability parallel conductor layout 240b of Bu Fen pliability parallel conductor layout 240a and part can be between the body 212 and backboard 230 of power panel 210.Because part pliability parallel conductor layout 240a, 240b between body 212 and backboard 230 are because of passing holes 212H respectively
1, 212H
2And be subjected to the interference of body 212, so that the bond strength between pliability parallel conductor layout 240a, 240b and the power panel 210 more strengthen.
Traditionally, the pliability parallel conductor layout only runs through the holes on the backboard so that its two ends electrically connect two lip-deep light source and the connectors that are positioned at backboard respectively, and wherein configuration place of light source and connector also need be yielded in the length of pliability parallel conductor layout and position.Compared to present embodiment, known techniques is not only seeming very weak in conjunction with considering of pliability parallel conductor layout and power panel, and also quite limited aspect the cost of saving the pliability parallel conductor layout.In addition, in the past for fixing pliability parallel conductor layout, also can utilize adhesive tape and the pliability parallel conductor layout is sticked on the backboard.This measure on foot increases the complexity of finishing light source module, and also can the derive problem of reliability of the quality of adhesive tape.
Yet in the present embodiment, power panel 210 has holes 212H
1, 212H
2, holes 212H wherein
1, 212H
2The phenomenon that pliability parallel conductor layout 240a, 240b and body 212 are interfered with each other, and then strengthen the bond strength between each member in the light source module 300.On the other hand, compared to traditional design, the length of pliability parallel conductor layout 240a, 240b significantly shortens, thereby saves the cost of pliability parallel conductor layout 240a, 240b.In addition, the light source module 300 of present embodiment can need not to use the combination of finishing under the situation of adhesive tape between its each member, the cost consumption of being brought when using adhesive tape and man-hour is consuming time and the complicated degree of simplifying the making step of light source module 300 except saving, and the reliability doubt that adhesive tape caused can not take place naturally yet.Thus, the yield of light source module 300 can significantly promote, and the quality of light source module 300 also with raising.
In sum, power panel of the present invention has at least one holes, this holes is applied in the light source module of the present invention, and then the bond strength between each member is promoted in the light source module, and the cost of the pliability parallel conductor layout in the light source module can significantly reduce.Generally speaking, the structural design of power panel of the present invention makes light source module of the present invention have good quality.
Though the present invention discloses as above with embodiment; right its is not in order to limit the present invention, to have in any affiliated technical field and know the knowledgeable usually, without departing from the spirit and scope of the present invention; when doing a little change and retouching, so protection scope of the present invention should be as the criterion with the claim scope.
