The integral substrate is comb-shaped. A cross integral design is adopted conveniently, an integral PCB (printed circuit board) can be cut into two substrates conveniently, the lamp strips seem to be separate but are finally connected together, and smoothness of the integral component and brightness uniformity are guaranteed. Raw materials can be sufficiently utilized as compared with an existing integral design. As compared with a single-strip design, the multiple lamp strips share the same substrate, the quantity of connecting sockets and the quantity of connecting wire harnesses can be minimized, technological operation is simple, and reliability is high. Besides, the luminous component is attached onto a rear panel in a locking manner by depression bars and support columns, on the one hand, the PCB substrate has a movement range for heat expansion and cold contraction and accordingly cannot deform easily, and on the other hand, the technological operation is simple and speedy.
Description
Technical field
The utility model relates to module backlight, relates in particular to a kind of luminescence component that is used for down straight aphototropism mode set.
Background technology
Module backlight is one of key components and parts of panel of LCD; Its function is well-off brightness and the light source that is evenly distributed, and makes its normally show image, and down straight aphototropism mode set wherein directly is positioned over illuminating module the below of liquid crystal panel; Generally be applied to satisfy the more demand of high brightness; The normal light source that adopts is the LED particle, uses the advantage of LED to be that it has the advantages that reaction speed reaches high color rendering soon, and compliance with environmental protection requirements more; Even for the exiting surface bright dipping, when necessarily requiring to make luminescence component the LED particle almost put with the mode that is covered with and be effective.
The traditional way of down straight aphototropism mode set luminescence component has following two kinds at present:
The one, adopt the monoblock type modular design; The luminescence component of this mode is exactly an even distribution LED particle on a monoblock pcb board, is fixed on pcb board above the backboard then, and this kind mode thermal diffusivity is bad; Time has been grown and can cause the pcb board buckling deformation, influences brightness uniformity; Need the bigger pcb board of monoblock area when producing in addition, corresponding sheet material waste is more, and cost is high.
The 2nd, adopt wall scroll formula lamp plate or lamp bar to combine, a kind of LED-backlit module is disclosed like document CN101526185A, comprise a backboard; One or more LED lamp plates place on the said backboard, and said LED lamp plate comprises LED substrate and a plurality of LED lamps source; One LGP places on the said LED substrate; Wherein, Said LED-backlit module also comprises fixed part; Said fixed part tow sides all are formed with clamping part; Be formed with joint end or the blocked hole that is complementary with said clamping part on said LED substrate and the backboard, the positive and said LED substrate engaging of said fixed part is connected, and said fixed part reverse side is connected with said backboard engaging.The light source assembly that this mode forms; The quantity of lamp plate or lamp bar is too much and be difficult for installation, can not guarantee the flatness of the equidistant and lamp bar between lamp plate and the lamp bar after installing simultaneously, possibly cause brightness disproportionation; In addition; Adopt the design of this mode, every lamp plate or all will have a socket to be directly connected to LED drive plate or be connected on the LED drive plate above the lamp bar through PCB transition connection strap through connecting line, can cause socket and rat tail too much, complex structure.
The utility model content
The purpose of the utility model provides a kind of luminescence component that is used for down straight aphototropism mode set, can solve the problem of above-mentioned existence.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of luminescence component that is used for down straight aphototropism mode set comprises substrate and LED lamp bar placed on it, and said substrate integral body is pectination.
Special, the spacing of LED lamp equates on the said lamp bar.
Preferably, the spacing of said adjacent lamps bar equates.
Further, on the said substrate gang socket is installed, is used for of the connection of basic onboard led lamp with drive plate.
Further, said substrate locks with the backboard support column through press strip and is connected.
Further, the spacing distance of said lamp bar is not less than the width of lamp bar, and the cutting clout can be used for forming another piece substrate.
The beneficial effect of the utility model does, the convenient employing intersected integral design, and the whole plate of PCB can form two base boards easily through cutting; Every lamp bar sees that formula like separately but finally all connect together, has guaranteed the planarization and the brightness uniformity of whole assembly, compares existing integral design; Can make full use of raw material; Compare the design of wall scroll formula, the shared substrate of a plurality of lamp bars can drop to gang socket, rat tail quantity minimum; The simple and reliable property of technological operation is high, has guaranteed the market competitiveness simultaneously; This luminescence component locks on backboard through press strip and support column, and the PCB substrate has movable scope owing to expand with heat and contract with cold on the one hand, and is not yielding; Technological operation simple and fast on the one hand in addition.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the said luminescence component of embodiment;
Fig. 2 adopts the intersection integral design to produce the piecemeal sketch map of the said luminescence component of embodiment;
Fig. 3 is that said luminescence component is installed on the mounting structure sketch map on the backboard;
Among the figure:
1, PCB substrate; 2, LED lamp; 3, fixing hole; 4, lamp bar; 5, gang socket; 6, backboard; 7, press strip.
The specific embodiment
As shown in Figure 1, provided the said specific embodiment that is used for the luminescence component of down straight aphototropism mode set of the utility model, to form by PCB substrate 1 and LED lamp bar 4 placed on it, PCB substrate integral body is pectination, and all lamp bars 4 are co-located on the said substrate.For guaranteeing the uniformity of luminescence component brightness, the spacing of LED lamp 2 equates on the said lamp bar 4, and the spacing of adjacent lamps bar 4 equates simultaneously; The fixing hole 3 that is provided with separated by a distance on the PCB substrate 1, make things convenient for substrate in process of production with the location of mould and the assembling of LED lamp 2, compare wall scroll formula design, can guarantee the planarization of whole assembly.
