Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
As an aspect of of the present present invention, a kind of lamp bar is provided, as shown in Figures 4 to 6, multiple illuminating parts 12 that this lamp bar comprises matrix 11 and is arranged on this matrix 11, matrix 11 comprises multiple lug boss 111 and is arranged on the spacer portion 112 between adjacent two lug bosses 111, multiple illuminating part 12 is separately positioned on multiple lug boss 111, and/or multiple illuminating part 12 is separately positioned in multiple spacer portion 112.Illuminating part 12 can be light emitting diode.
In the present invention, lug boss 111 protrudes from spacer portion 112, compared with prior art, the surface area of the matrix 11 in the present invention increases, that is, the area of dissipation of matrix 11 increases, thus improve the radiating effect of lamp bar, improve the light quality of illuminating part 12, and extend the service life of illuminating part.Improve in the technical scheme of lamp bar radiating effect with existing other, the lamp bar structure in the present invention is comparatively simple, can improve radiating effect without the need to increasing other radiator structures.
It should be noted that, above-mentioned " lug boss 111 protrudes from spacer portion 112 " refers to, for the surface being provided with illuminating part 12 of matrix 11, lug boss 111 protrudes from spacer portion 112.Be understandable that, for the surface deviating from illuminating part 12 of matrix 11, spacer portion 112 protrudes from lug boss 111.
Illuminating part 12 can be LED, illuminating part 12 all can be arranged on lug boss 111 (as shown in Figure 4 and Figure 5), or be arranged on (as shown in Figure 6) in spacer portion 112, also can the illuminating part 12 of a part of quantity be arranged on lug boss 111, another part is arranged in spacer portion 112, as long as matrix 11 can be made can to dispel the heat to the even heat that multiple illuminating part 12 produces.
As a kind of detailed description of the invention of the present invention, lug boss 111 comprises protruding fixed part 111a and protruding connecting portion 111b, protruding connecting portion 111b is connected between protruding fixed part 111a and adjacent spacer portion 112, and protruding fixed part 111a is used for fixing illuminating part 12.As noted before, illuminating part 12 can be arranged on lug boss 111, or is arranged in spacer portion 112, and when illuminating part 12 is arranged on lug boss 111, as shown in Figure 4 and Figure 5, protruding fixed part 111a is used for fixing illuminating part 12.
Further, the angle between protruding connecting portion 111b and protruding fixed part 111a, between 60 ° ~ 120 °, increases as much as possible to make the surface area of matrix 11.Preferably, protruding connecting portion 111b can be mutually vertical with protruding fixed part 111a, thus make space one timing shared by matrix 11, the surface area of matrix 11 is relative to increasing more in prior art, when angle between protruding connecting portion 111b and protruding fixed part 111a is 90 °, the surface area of matrix 11 is the surface area of protruding connecting portion 111b relative to the area increased in prior art.Aborning, the angle between protruding connecting portion 111b and protruding fixed part 111a can be set to 90 ° ± 5 °.
Protruding fixed part 111a, protruding connecting portion 111b are identical with the thickness of spacer portion 112, thus prevent the subregion thickness of matrix 11 thicker, to ensure the heat dispersion of matrix 11 while increase matrix 11 area of dissipation.The side view of lamp bar as shown in Figure 5.
In order to improve the radiating effect of lamp bar, matrix 11 is made up of metal material, and described metal material can be iron, copper, aluminium etc., also can be alloy material.The method of punching press can be adopted to form the structure of above-mentioned matrix 11.
Preferably, described metal material can comprise aluminium, and due to the good heat dispersion performance of aluminium, low price and easily processing, therefore adopts aluminium can improve radiating effect as the material of matrix 11, reduce production cost.
Above-mentioned is description to lamp bar provided by the present invention, can find out, in the present invention, the matrix of lamp bar comprises lug boss and spacer portion, lug boss protrudes from spacer portion, thus make length one timing of lamp bar, the surface area of matrix increases, thus improves the radiating effect of lamp bar, improve the light quality of illuminating part, extend the service life of illuminating part.
As another aspect of the present invention, provide a kind of backlight, comprise above-mentioned lamp bar.Because the radiating effect of above-mentioned lamp bar is better, the light quality that illuminating part is launched improves, and therefore, use the light-out effect of the backlight of described lamp bar better, the life-span is longer.
Described backlight can be side-edge type backlight, described backlight also comprises light guide plate, described lamp bar is arranged on the side of the backboard of backlight, illuminating part is towards the incidence surface emission of light of described light guide plate, for the ease of the setting of lamp bar, described backboard is provided with the groove corresponding with spacer portion 112, between adjacent two described grooves, forms casting lug thereon, spacer portion 112 is arranged in groove, and described lug boss is arranged on described casting lug thereon.Because described groove and spacer portion 112 correspondence are arranged, therefore, described lug boss and described casting lug thereon are also corresponding, thus are fixed on backboard by lamp bar.Preferably, the shape of described groove and described casting lug thereon can be consistent with the shape of described lug boss and described spacer portion, to make the back side of matrix 11 and described backboard fit completely, thus keeps the stable setting of lamp bar on backboard.
Further, jointing material can be provided with between the backboard of described backlight and matrix 11, with further fixed light bar, the backboard of the subregion of matrix 11 and described backlight can only bond by described jointing material, also whole matrix 11 all can be bonded with the backboard of described backlight, as long as lamp bar can be fixed on backboard.
As another aspect of the invention, provide a kind of display unit, this display unit comprises above-mentioned backlight.Because the radiating effect of lamp bar of the present invention is better, thus can improves the light-out effect of backlight, thus improve the display effect of display unit.
