Abstract
The utility model discloses an L-shaped tube group of a side light type backlight module, which comprises two L-shaped tubes and a connector which is applied to connect the L-shaped tubes and a inverter, wherein the low pressure end of the two L-shaped tubes is connected by one wire, the high pressure end of the two L-shaped tubes is connected on the connector by two wires. The L-shaped tube group of the side light type backlight module of the utility model reduces the connector quantity and the wire material, which saves the trimming time and the assembly working time for fixing the low pressure wire, and further improve the manufacturing efficiency.
Description
Technical field
The utility model relates to a kind of side-light type module backlight of LCD, particularly a kind of L shaped light tube group that is used for the side-light type module backlight of LCD.
Background technology
LCD (LCD) is widely used in computer, communication apparatus and other various displays.General LCD mainly is made up of liquid crystal panel and module backlight.Wherein liquid crystal panel itself is not luminous, and the light source of panel is provided by module backlight.Module backlight can be divided into two kinds of side-light type and straight-down negatives.
LCD adopts the side-light type back light module unit structure mostly, light source arrangement is in the side of LGP incidence surface, light source directly or indirectly enters LGP and propagates, via the optics site of LGP below and reflector plate to total reflection phenomenon destruction after, light source spreads ejaculation at an angle by the front of LGP, is distributed in the light-emitting zone uniformly.Via blooming piece the light source angle of visibility is adjusted again, in the angle of visibility that makes light can accumulate in LCD is selected, with of the characteristic requirement of fluid,matching crystal display to optics.
The fluorescent tube that side-light type module backlight uses has straight shape and L shaped two kinds.L shaped fluorescent tube be general CCFL (Cold Cathode Fluorescent Lamps, CCFL), it has, and caliber is thin, the life-span is long and the light efficiency advantages of higher, it is low-pressure end electrode and high-pressure side electrode that the two ends of L shaped fluorescent tube have an electrode respectively.The L shaped configuration of tube mode of prior art as shown in Figure 1.The low-pressure end electric wire 2 of two L shaped fluorescent tubes 1 need be walked around very long distance and arrive the fluorescent tube high-pressure side, is connected on the connector 5 with fluorescent tube high-pressure side electric wire 3.Every L shaped fluorescent tube 1 must correspondingly dispose a connector 5, by the high-pressure side electrode discharge driving of L shaped fluorescent tube.Low-pressure end and high-pressure side at every L shaped fluorescent tube 1 have a rubber cap 4 to be used for the location respectively.
There is following shortcoming in the L shaped light tube group of existing side-light type module backlight: the one, and the low-pressure end electric wire need extend to high-pressure side, is connected on the connector with the high-pressure side electric wire again, needs a large amount of wire rod costs; The 2nd, every L shaped fluorescent tube must correspondingly dispose a connector and two rubber caps, needs a large amount of connector and rubber cap; The 3rd, when assembling arrangement and fixedly low tension wire is loaded down with trivial details consuming time.
Summary of the invention
For addressing the above problem, the utility model provides that a kind of material expends less, the L shaped light tube group of side-light type module backlight easy to assembly.
For achieving the above object, the L shaped light tube group of side-light type of the present utility model module backlight, comprise two L shaped fluorescent tubes and the connector that is used to be connected described L shaped fluorescent tube and inverter, the low-pressure end of described two L shaped fluorescent tubes is linked to each other by a wire, and the high-pressure side of described two L shaped fluorescent tubes is connected on the described connector by two wires.
The low-pressure end of described L shaped fluorescent tube, high-pressure side are connected by welding manner with electric wire.
The bending part of described L shaped fluorescent tube utilizes heat-shrinkable T bush to coat.
L shaped light tube group by side-light type of the present utility model module backlight, because two low-pressure ends of two L shaped fluorescent tubes are connected to form the loop, high-pressure side electric wire by high-pressure side is connected on the connector, saved a large amount of low tension wires, and the connector that fluorescent tube is required and the quantity of rubber cap reduce by half, and have saved inventory charge greatly.
The L shaped light tube group of side-light type of the present utility model module backlight has been saved arrangement and fixing assembling man-hour of low tension wire, has improved production efficiency.
Description of drawings
Fig. 1 is the configuration mode schematic diagram of the L shaped light tube group of existing side-light type module backlight;
Fig. 2 is the configuration mode schematic diagram of the L shaped light tube group of the utility model side-light type module backlight;
Fig. 3 is the structural representation of the L shaped light tube group of the utility model side-light type module backlight.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 2 is the configuration mode schematic diagram of the L shaped light tube group of the utility model side-light type module backlight, and Fig. 3 is the structural representation of the L shaped light tube group of the utility model side-light type module backlight.As shown in the figure, the L shaped light tube group of the utility model side-light type module backlight comprises two L shaped fluorescent tubes 21, low-pressure end electric wire 22, two high-pressure side electric wires 23, connector 24, the low-pressure end of two L shaped fluorescent tubes 21 is weldingly connected by low-pressure end electric wire 22, high-pressure side electric wire 23 of high-pressure side welding of each L shaped fluorescent tube, two high-pressure side electric wires 23 are connected on the connector 25, and connector 24 is used to connect L shaped fluorescent tube 21 and inverter (not shown).Two electrodes of fluorescent tube high-pressure side electrion simultaneously drive.
The low-pressure end of described L shaped fluorescent tube 21, high-pressure side and low-pressure end electric wire 22, high-pressure side electric wire 23 can also by connector or screw crimping, shell fragment crimping etc. reliably mode be connected.
The low-pressure end of two L shaped fluorescent tubes 21 is fixed in the low-pressure end rubber cap 24, and low-pressure end electric wire 22 penetrates low-pressure end rubber cap 24, utilizes low-pressure end rubber cap 24 location; The high-pressure side of two L shaped fluorescent tubes 21 is fixed in the high-pressure side rubber cap 26, and high-pressure side electric wire 23 penetrates high-pressure side rubber cap 26, utilizes high-pressure side rubber cap 26 location.
The bending part of L shaped fluorescent tube 21 utilizes heat-shrinkable T bush 27 to coat, and avoids light leakage phenomena to take place.
The light tube group configuration mode of the side-light type back light module that present embodiment provided, its needed number of connectors reduces by half than prior art, the low-pressure end electric wire consumption that needs simultaneously is less, assembles very conveniently, has saved wide variety of materials and has expended and assemble man-hour.
