The backlight plate has good heat dissipation and backlight effects, and is particularly suitable for an advertising board in a hot outdoor environment.
Description
Technical field
The utility model relates to a kind of backlight, is specifically related to a kind of backlight that is applicable to large board.
Background technology
Existing billboard is generally to adopt LED etc. as backlight, and for large-scale billboard, an energy part that is transferred to LED is exported as light, and a part is converted into heat.Due to the general outdoor layout of billboard, in hot environment, large board can gather a large amount of heats, if can not shed in time, easily affects life of product.And existing billboard, in order to increase brightness, need to increase the quantity of LED, but this also can increase caloric value, and backlight effect is also bad.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of backlight.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of backlight, it is characterized in that, comprise panel, multiple LED-backlit plate module, power module, heat dissipating housing, described LED-backlit plate module connects power module, described panel comprises the first relative side and the second side, and described the first side is fixedly connected with heat dissipating housing, forms a seal cavity between the first side and heat dissipating housing, in described seal cavity, fill cooling fluid, described LED-backlit plate module and power module are installed in described the second side.
Aforesaid a kind of backlight, is characterized in that, described heat dissipating housing is square.
Aforesaid a kind of backlight, is characterized in that, described panel is fine aluminium panel or aluminium alloy panel.
Aforesaid a kind of backlight, is characterized in that, described heat dissipating housing is fine aluminium panel or aluminium alloy panel.
Aforesaid a kind of backlight, is characterized in that, on described heat dissipating housing, offers plug.
Aforesaid a kind of backlight, is characterized in that, described cooling fluid is water.
Aforesaid a kind of backlight, is characterized in that, is provided with multiple oval salient points in described the second side.
Aforesaid a kind of backlight, is characterized in that,, the major axis of described oval salient point and the ratio of minor axis are between 3.15-4.43, and the thickness between described oval salient point is identical.
Usefulness of the present utility model is: a kind of backlight of the present utility model has good radiating effect and backlight effect, is specially adapted to the billboard in hot environment in the open.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model panel the second side;
Fig. 2 is the structural representation of the utility model panel the first side;
Fig. 3 is the side structure schematic diagram of the utility model backlight.
The implication of Reference numeral in figure:
1, panel, 2, the second side, 3, backlight module, 4, power module, 5, oval salient point, 6, the first side, 7, heat dissipating housing, 8, plug.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Shown in Fig. 1, a kind of backlight of the utility model, comprise panel 1, multiple LED-backlit plate module 3, power module 4, heat dissipating housing 7, LED-backlit plate module 3 connects power module 4, panel 1 comprises that the first relative side 6 and the second side 2, the first sides 6 are fixedly connected with heat dissipating housing 7, form a seal cavity between the first side 6 and heat dissipating housing 7, in seal cavity, fill cooling fluid, LED-backlit plate module 3 and power module 4 are installed in the second side 2.In the utility model, select LED-backlit plate module 3 to provide brightness for billboard, selecting power module 4 to realize powers to LED-backlit plate module 3, select panel 1 to fix LED-backlit plate module 3 and power module 4, because LED-backlit plate module 3 directly contacts with panel 1 with power module 4, the heat that LED-backlit plate module 3 and power module 4 produce passes in the cooling fluid between heat dissipating housing 7 and backlight by panel 1, cooling fluid is selected the liquid that specific heat capacity is high, and the utility model is preferably water.In reality, on heat dissipating housing 7, plug 8 can be set, by plug 8, pour into cooling fluid, then seal plug 8.The heat of cooling fluid can shed by heat dissipating housing 7.Installation heat pipe heat radiation also can be set on heat dissipating housing again.Actual specific shows, arranges after heat dissipating housing, and more LED-backlit plate module 3 can be set in backlight, and panel 1 also can arrange larger, also can not produce heat and too much gather simultaneously.
For the purpose of processing, in engineering, preferably heat dissipating housing is square, but the utility model is not got rid of the heat dissipating housing that can select other shapes.Panel 1 of the present utility model is preferably selected and is not easy the material that burn into quality is light, reflecting effect good, heat-transfer effect is good, is preferably fine aluminium panel or aluminium alloy panel in reality.Heat dissipating housing of the present utility model is preferably selected and is not easy the material that burn into quality is light, heat-transfer effect is good, is preferably fine aluminium panel or aluminium alloy panel in reality.
Below, as the utility model, further improve, in the second side 2, be provided with multiple oval salient points 5.The utility model arranges these oval salient point 5 reasons and is to increase the Integral back light effect of the utility model backlight, this is because there is gap between LED-backlit plate module 3, like this, when LED-backlit plate module 3 is luminous, between LED-backlit plate module 3, will produce dark space, cause Integral back light effect not good.Existing way is to dwindle spacing between LED-backlit plate module 3, certainly will will increase like this quantity of LED-backlit plate module 3, easily raises the cost and strengthens heat dissipation capacity.The utility model has adopted oval salient point 5, and oval salient point 5 can improve LED-backlit plate module 3 and send scattering of light effect, improves the uniformity of light in the utility model product.Select the salient point of elliptical shape better than selecting other shapes, because ellipse diffuse scattering light better.Actual test shows, when the major axis of oval salient point 5 and the ratio of minor axis are between 3.15-4.43, when thickness between oval salient point 5 is identical, can make brightness everywhere of backlight of the present utility model and evenness errors below 10%.
A kind of backlight of the present utility model has good radiating effect and backlight effect, is specially adapted to the billboard in hot environment in the open.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
