Description
Technical field
The present invention relates to lamp box fields, and in particular to a kind of constructive method 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,

Doubling circuit between the lamp bar forms a kind of backlight module of strip；Supporing shell is a kind of by casing substrate and the shell
Both sides edge department is connected on rear side of structure base board the fixed card slot on shell, the casing substrate between the fixed card slot on the shell
Light trough and casing substrate both sides edge department on the shell of the opening of upper setting backwards is on the shell with detent of front projection
The profile that convex block is constituted is connected, and the light trough trench bottom on shell is equipped with the lamp hole of multiple equally distributed light trough bottoms；Face
Cover is a kind of from panel, the panel two sides to the mask clamping close device structure of the mask side plate of rear projection and the mask side plate rear lateral portion
At section at the profile of U-shaped, mask clamping close device is connected together with the connection convex block on shell；Lamp bar includes lamp bar power connection end
Light source is equipped with the lamp hole of corresponding light trough bottom；The lamp bar is fixedly mounted in the light trough on shell, and light source is made to be placed in light trough bottom
In the lamp hole in portion, and lamp bar power connection end is connected via doubling circuit doubling.Then by more backlight modules by vertical or horizontal
Mutually splicing is mounted on fixed bracket, is fixed via the fixed card slot bolt on shell, the power connection end of doubling circuit is via confession
Electric line is connect with power supply power supply, to constitute modularization cambered surface lamp box.
According to the fixed card slot on above-described shell, the fixed card slot on the shell presses mirror settings, so that two
Fixed card slot notch on shell is opposite；Fixed card slot on above-mentioned shell from card slot bottom plate and the card slot bottom plate to inward side to
Two of protrusion are parallel to each other, keep the card slot cell wall of certain distance and the two clamp bar slots cell wall edge department relatively raised by mirror image
Card slot detent composition, keep certain distance between two clamp bar slot detents, to form a straight card slot notch, two cards
The step being respectively equipped between card slot bottom plate on the inside of groove groove wall on the inside of cell wall, the distance between the step on the inside of two cell walls
Cooperate with card slot notch size, card slot bottom plate is connect with both sides edge department on rear side of casing substrate.
According to above-described mask clamping close device, it is by being located at mask side plate interior sides far from after along the side plate of portion's protrusion
Limited block and be located at mask side plate interior sides strip on the side plate of portion's protrusion after and form；Mask is mounted on supporing shell
Front side, the limited block on side plate keep off the front side portion of the connection convex block on shell, and the strip on side plate is stuck in the connection on shell
The detent portion of convex block.
According to above-described backlight module, lamp bar is mounted in the light trough on shell, is fixed via expansion post；The expansion
Column is located between the lamp hole of the light trough bottom of the light trough bottom on shell, and lamp bar corresponds to expansion post equipped with the spacious hole in lamp bar, is somebody's turn to do
