Description
Technical field
The present invention relates to lamp box fields, and in particular to a kind of backlight module of modularization cambered surface lamp box.
Background technique
It is well known that the application of lamp box and be it is extensive, it is related to building field, industrial circle, commercial field, medical leads
Domain, advertizing field etc., wherein advertizing field should have the most extensively.
Currently, advertising lamp house structure mainly has the following two kinds: one is the lamp boxes of side entrance back source structure, mainly by leading
Tabula rasa and light source composition, are mounted on light guide plate side for light source, are equipped with light guiding points made of engraving or printing in light guide plate bottom.
Due to guide-lighting distance limitation, the lamp box of side entrance back source structure is applicable in the lesser product of light-emitting area.It is usually used in small dimension
Decoration painting, Window Display, plate lighting etc..But the two sides of light guide plate or surrounding setting light source, make light guide plate two sides or
There are the dark spaces caused by light source body for surrounding, cannot achieve no shadow splicing.Another kind is the lamp box of direct backlight source structure,
It is mainly made of panel, light source and cabinet, panel is mounted on cabinet front, light source is mounted on rear side of cabinet, light-dispersing effect
It is set by the distance between astigmatism plate and light source, therefore, the lamp house thickness of direct backlight source structure is far longer than side entering type
Back light unit, since it has the advantages such as brightness is high, light source controllability is strong, the application of direct-type backlight unit is extremely wide
It is general, such as advertising lamp box, signboard lamp house, guiding plate lamp box and show window lamp box.But the cabinet surrounding of direct-type backlight unit is
Lighttight box body wall, serious shadow can also be gone out between rear box by splicing, and therefore, also cannot achieve no shadow splicing.It is above-mentioned can
Know, mainstream advertising lamp box is only limitted to the lamp box of small breadth at present.The large format advertisement of outdoor advertising communication sphere is still stuck in
Painting advertisement, three faces turn over four kinds of advertisement, LED display advertisement and luminescent characters advertisement mainstream open air carriers.
With the development of the global economy, constantly promoting under the new situation in Global Urbanization and smart city, spirit text
Bright and material progress to significantly improve, more stringent requirements are proposed to visual aspects by people, the development of various promotional display terminals
It is more unprecedented surging.Therefore, there is an urgent need to develop the back light unit presentation device of large area light emitting, especially arc light-emitting surface
Backlight presentation device, such as cambered surface lamp box, arc dynamic lamp box and arc backlight show equipment, to meet the market demand.
Summary of the invention
Place and existing defect in order to overcome the deficiencies of the prior art, the present invention provide it is a kind of shine uniformly, structure it is simple,

Case；When support frame 9 is arc, the modular lamp box of composition is cambered surface lamp box；Since backlight module is strip, broad-ruler
Very little smaller, the tangent line for the arcwall face being spliced into is also smaller, so that modularization cambered surface lamp box shape is more beautiful；Due to the light source
Module 3 is mounted on the rear side of Housing Base 11, the dismounting of light source module 3 is influenced due to avoid the picture on front side of lamp box, thus just
In maintenance；Backlight module of the present invention can not only be spliced into the lamp box of large area light emitting, and can also be spliced into arc and shine
The mould lamp box in face.The modularization cambered surface lamp box formed is spliced by above-mentioned backlight module, uniform, structure is simple, shape with shining
It is beautiful, be easily installed advantage with maintenance.
Fixed card slot 12 on the shell according to above-described embodiment, as shown in Figures 2 to 4, consolidating on two shells
Card slot 12 is determined by mirror settings, so that 12 notch of fixed card slot on two shells is opposite；Fixed card slot 12 on the shell by
Card slot bottom plate 121 and the card slot bottom plate 121 are to inward side to the card slot cell wall of two of the protrusion certain distances that are parallel to each other, keep
122 and two clamp bar slots cell wall, 122 edge department formed by the relatively raised card slot detents 123 of mirror image, two clamp bar slot detents 123 it
Between keep certain distance, to form a straight card slot notch 12a, the inside of two clamp bar slot cell wall 122 and card slot bottom plate 121
Between be respectively equipped with step 124 on the inside of cell wall, the distance between step 124 on the inside of two cell walls and card slot notch 12a
Size cooperation, card slot bottom plate 121 are connect with 11 rear side both sides edge department of Housing Base.When installation, nut or bolt head are from fixation
It after 13 both ends of card slot are inserted in, and can be slided in fixed card slot 13, this fixed card slot 13 is conveniently adjusted fixed position.
Clamping close device 23 on the mask according to above-described embodiment, as shown in Figure 3, Figure 4, the engaging dress on the mask
23 are set by being located at limited block 23a of 22 inside of mask side plate far from after on the side plate of portion's protrusion and being located at 22 inside of mask side plate
Strip 23b composition after on the side plate of portion's protrusion；Mask 4 is mounted on 1 front side of supporing shell, the limited block on side plate
23a keeps off the front side portion of the connection convex block 14 on substrate, and the strip 23b on side plate is stuck in the detent of the connection convex block 14 on substrate
Portion.
According to above-described embodiment, a kind of light source module 3 provided by the invention is mounted on the fixation side of 11 rear side of Housing Base
Case: as shown in figure 3, the spacious hole 32 on light source module is fixed with the screws clamp slot 15 on substrate via screw.This fixation side
The advantage of the specific firm stable of case.
According to above-described embodiment, lamp bar 3 is mounted in the light trough 13 on shell, fixed via expansion post 131；The expansion post
131 are located between the lamp hole 13a of the light trough bottom of 13 bottom of light trough on shell, and the corresponding expansion post 131 of lamp bar 3 is equipped in lamp bar
Spacious hole 32, the spacious hole 32 in the lamp bar is connected together with expansion post 131, consequently facilitating assembly.
According to above-described doubling circuit, for convenient for lamp bar 3 for electrical connection, a kind of doubling connection provided by the invention
Scheme: as shown in Figures 3 to 5, above-mentioned lamp bar power connection end is a kind of connector body 30 being welded in lamp bar 3, doubling circuit 4
Be made of multiple connector plugs 41 and the electric wire 4a being connected between the connector plug 41, the connector plug 41 with connect
Device socket 30 connects, consequently facilitating connection.
According to above-described doubling circuit, for convenient for lamp bar, for electrical connection, another kind doubling provided by the invention connects
Connect scheme: as shown in Figure 6 to 7, above-mentioned lamp bar power connection end is a kind of connector body 30 being welded in lamp bar 3, doubling electricity
Road 4 corresponds to the connector plug 41 that the connector body 30 of lamp bar 3 is arranged with doubling circuit board 4b by doubling circuit board 4b, and
The power connection end of line circuit 4 is located at close to the intermediate position of doubling circuit board 4b, and connector plug 41 is connect with connector body 30,
Doubling circuit power connection end 42 is connect with power supply line 6.In this way, being not only convenient for connection, and route is more neat and artistic.
Below with reference to modularization cambered surface lamp box of the present invention backlight module Detailed description of the invention to above-described embodiment into one
Step corrective measure clearly and completely describes.
