Description
Technical field
The utility model relates to a kind of LED lamp bar, relates in particular to a kind of with protruding LED lamp bar.
Background technology
In modern society, LED display is visible with carving, and arrives greatly market LED curtain wall, little of shop sign, all adopt LED display, described LED display is to be all packed on buildings outer wall by a plurality of LED display module splicings, and the installation of conventional display screen needs outside the building on wall, to hole, and squeezes into steel nail, keel are installed, LED display module is fixed on keel in order, the power lead of LED display module, signal wire is connected simultaneously, completed the installation of one side LED display.
The size of LED display overall resolution is that the density of surface mounted light on the LED lamp bar in LED display module determines, the density of surface mounted light is closeer, the resolution of LED display is higher, that just sees is more clear, Picture Showing is better, so the performance of LED display depends on the performance of LED display module.
The density of surface mounted light increases, just need more LED lamp bar, an aluminium section bar of every LED lamp bar configuration, LED display overall weight will be increased, heavier LED display can increase the load of skin, add the environmental factors such as snow load and wind carry, can further increase the weight of LED display, make skin for a long time in potential safety hazard, secondly intensive LED lamp bar is arranged and is made the penetrating rate of LED display module not high, not only impact heat radiation, and can strengthen unit area snow load and wind carries.
So the design of LED lamp bar concerns the performance of whole LED screen.Traditional LED lamp bar is that aluminium section bar and PCB lamp plate form, aluminium section bar be one rectangular, xsect is matrix, the PCB lamp plate that a row is inlaid with LED lamp grain embeds in the groove of aluminium section bar, and fixes by encapsulating.Technique preferably LED lamp bar can be on PCB lamp plate enveil, increase the properties such as its waterproof, fixing, display effect.But LED lamp bar is in any case all on an aluminium section bar, to join a row LED lamp, want the resolution that increases LED screen need increase lamp bar quantity, will make LED screen overall weight increase, penetrating rate reduces, in order to obtain high-resolution, have the LED screen compared with high penetration rate simultaneously, need redesign LED lamp bar.
Summary of the invention
It is a kind of with protruding LED lamp bar that the purpose of this utility model is to provide, the in the situation that of same resolution, reduce the use of LED lamp bar, aluminium section bar, not only reduce costs, and effectively reduce deadweight, unit area snow load, the windage of LED display module, have higher penetrating rate simultaneously.
The utility model is achieved through the following technical solutions:
There is a protruding LED lamp bar, comprising: aluminium section bar, PCB lamp plate; Described aluminium section bar need have the most basic horizontal support portion and the vertical supporter of both sides as the main support member of LED lamp bar, makes the shape of aluminium section bar rank street face be " H " shape, and PCB lamp plate is embedded between the vertical supporter of both sides as light source; The relative inwardly protruding of vertical supporter of described aluminium section bar both sides, form spacing preiection, described LED lamp bar also has a PC base, LED lamp plate is fixed on the pedestal of this PC base, both sides, described PC pedestal base below have respectively button pin, described two button pin extend out to the spacing preiection below of aluminium section bar vertical supporter relatively, both sides vertical supporter upper surface just in time withstands pedestal lower surface, aluminium section bar and PC base are well fixed together, and described PC base rank street face is " π " shape;
In order to fix more PCB lamp bar on an aluminium section bar, the structure that changes aluminium section bar is comparatively loaded down with trivial details in technique, cost is also higher, but also can increase the weight of aluminium section bar, so PC base has good plasticity, change its shape and in technique, be easy to realize, cost is also lower, especially the quality of PC material is also very light, so this technology becomes " rich " font by described PC base from stripe shape, and PCB lamp plate becomes " rich " font from stripe shape equally;
PCB lamp plate can be arranged two LED lamp grains on original lamp grain node like this, and the both sides that are distributed in original lamp grain node that this two LED lamp grain is average make whole piece LED lamp plate form two row LED lamps, has realized and on an aluminium section bar, has loaded two row LED lamps.
Reach the object of loading two row LED lamps on an aluminium section bar, not necessarily leave no choice but PC base and PCB lamp plate all to make " rich " font, be namely positioned at arranging that the lamp grain of described both sides can misplace, only need to guarantee original interval of adjacent lamps grain.
The utility model is fixed a PC base between original aluminium section bar and PCB lamp plate, utilize cleverly the features such as PC material light weight and plasticity are strong that this PC base designs is become to " rich " font, PCB lamp plate is designed to " rich " font too, can distinguish lamp grain on position in the both sides of the original lamp grain of PCB lamp plate like this, form two row LED lamps, realize the effect on an aluminium section bar with two row LED lamps, the in the situation that of same resolution, reduce LED lamp bar, the use of aluminium section bar, not only reduce costs, and effectively reduce the deadweight of LED display module, unit area snow load, windage, have higher penetrating rate simultaneously.
