Embodiment
With reference to Fig. 2 a, backlight module 1 of the present invention comprises two holding frame for luminous tube 10, a backboard 20, a plurality of fluorescent tube 30 and two supporters 40.Will be appreciated that backlight module 1 also comprises other assemblies such as diffuser plate and blooming piece, but, omit its diagram and related description at this because other assemblies such as diffuser plate and blooming piece are identical with the known backlit module.In addition, supporter 40 is identical with known technology, and it is in order to support the two ends of each fluorescent tube 30.
With reference to Fig. 2 b, 3a and 3b, holding frame for luminous tube 10 is in order to support a plurality of fluorescent tubes 30 (being four in Fig. 2 a), and each holding frame for luminous tube 10 comprises a substrate 11, a plurality of support portion 12, a plurality of maintaining part 13 and two joint assemblies 14, and wherein each support portion 12 and the maintaining part 13 corresponding with it constitute a fixation kit.In addition, will be appreciated that,, be not limited to this, quantity is set adjusts according to the quantity that is provided with of fluorescent tube of holding frame for luminous tube though in Fig. 2 a, only show two holding frame for luminous tube 10.
In addition, under the prerequisite of considering reflecting effect, it is preferred that each holding frame for luminous tube 10 is set up in the mode that is not located along the same line each other.In the same manner, can in substrate 11, form a plurality of notch parts 111, reducing the shared area of holding frame for luminous tube 10 as far as possible, and then guarantee the effect that reflects.In addition, will be appreciated that,, be not limited to this, be provided with thereon as long as the shape of substrate 11 can make support portion 12, maintaining part 13 and engage assembly 14 though in Fig. 3 a, only in substrate 11, form four notch parts 111.
Each support portion 12 is arranged on the upper surface 11a of substrate 11, and has an arc surface 121 respectively, and fluorescent tube 30 is placed on the arc surface 121 of support portion 12.It should be noted that the curvature of arc surface 121 shown in Fig. 3 c, is the line contact thus, thereby can reduces contact area between the two as far as possible less than the curvature of fluorescent tube placed thereon 30 between fluorescent tube 30 and the support portion 12.
Each maintaining part 13 is arranged in the substrate 11 in the mode corresponding with support portion 12, and has two right cylinders 131 respectively, and it lays respectively at the both sides of corresponding support portion 12.In addition, each right cylinder 12 position approximately therebetween is formed with a barb 132, and it extends towards direction of substrate 11, with fluorescent tube 30 butts that are placed on the support portion 12 so that fluorescent tube 30 is fixedly remained on the support portion 12.
Have, because the shape of barb 132 forms the shape of switching the order, this just can put into fluorescent tube 30 on the support portion 12 easily again, but is difficult for therefrom taking out.In addition, because barb 132 is positioned at the middle part of right cylinder 12 haply, when desire is taken out fluorescent tube 30, can just can take out fluorescent tube 30 easily by the right cylinder 131 that pulls open barb 132 tops.
In addition, in Fig. 2 b, two right cylinders 131 of maintaining part 13 are on same surface level (the y coordinate of two right cylinders 131 is identical), but be not limited to this, considering under the factor that light advances, the right cylinder 131 ' of same maintaining part 13 ' is staggered (dislocation), backlight module 10 ' as shown in Figs. 4a and 4b, can reduce whereby has too many light to be blocked on same surface level.In addition, support portion 12 and maintaining part 13 can be integrally formed in substrate 11.
Each engages on the lower surface 11b that assembly 14 is arranged on substrate 11, and has a bar 141 and a semi-girder 142 respectively, as shown in Figure 5.In addition, backboard 20 is being formed with a conjugate foramen 21 corresponding to the position that engages assembly 14, and conjugate foramen 21 has a large-diameter portion 211 and a minor diameter part 212.When desiring in conjunction with holding frame for luminous tube 10 in backboard 20, after making joint assembly 14 enter in the conjugate foramen 21 via large-diameter portion 211, then, move along as shown in Figure 5 arrow and to engage assembly 14 up to entering minor diameter part 212, engage this moment the bar 141 of assembly 14 and semi-girder 142 respectively with minor diameter part 212 butts, make joint assembly 14 engage and be fixed in the conjugate foramen 21, and then holding frame for luminous tube 10 is fixed on the backboard 20 with minor diameter part 212.
As mentioned above, because holding frame for luminous tube only contacts with fluorescent tube with the barb (put and contact) of support portion (line contact) and maintaining part, promptly adopt the design of two one lines to reduce the contact area of fluorescent tube and holding frame for luminous tube, can reduce the amount that the initial stage heat is pulled away from surface of the light tube, just can keep surface of the light tube temperature homogeneity preferably thus, minimizing produces slightly dark situation because of support place initial stage surface temperature is lower, also can reduce the area that light is blocked.
Though the present invention discloses as above with preferred embodiment; but it is not that any those skilled in the art is not in breaking away from design of the present invention and scope in order to qualification the present invention; can make a little change and retouching, so protection scope of the present invention is defined with accompanying Claim.
