Background technology
Backlight progressively forms research and development focus, and its structure, primarily of compositions such as light source, light guide plate, optical film sheet, plastic frames, has the features such as brightness is high, the life-span long, luminescence is even.The service life of LED backlight is longer than EL, and uses DC voltage, is usually applied to small-sized monochrome display, such as phone, remote controller, micro-wave oven, air-conditioning, instrument and meter, stereo audio equipment etc.The breakthrough raising of LED luminance and production cost reduce, so go into overdrive to research and develop the back light system CCFL backlight as an alternative that LED is light source, are the important directions of Ge great backlight manufacturer in the future.
This case it is important to note that existing LED backlight system also exists a lot of defect, as: lighting angle is limited, and uniform light degree is poor, and visual effect brightness is lower; Electric wire on whole plate face exposes and not neatly, safety coefficient is lower, is easy to have an impact to other circuit; Constant intensity is lower, and radiating effect is poor.Therefore, for above aspect, need reasonably to improve prior art.
Utility model content
For above defect, the LED backlight system that the utility model provides the increasing of a kind of lighting angle, uniform light, visual effect brightness increase, whole plate face do not have exposed electric wire, safety coefficient are higher, simple installation, radiating effect are better, be conducive to extending LED service life, can reduce costs, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of LED backlight system, comprises diffuse reflector, heat-dissipation aluminum sectional material, aluminium base and LED lens light source, is weldingly fixed on heat-dissipation aluminum sectional material outside each diffuse reflector by bonding or riveting;
Each heat-dissipation aluminum sectional material upper surface middle part offers a slot and this slot inner horizontal lays one piece of aluminium base, each block aluminium base is evenly arranged some LED lens light sources;
Each aluminium base wherein one end sets up a binding post and every two adjacent binding posts connect wire respectively by one connects, and each binding post being positioned at outermost two aluminium bases is drawn one separately again and connected wire and be connected to LED driving light source; Each LED lens light source outer surface arranges lens.
Correspondingly, described diffuse reflector can be set to several.
With leg bottom described heat-dissipation aluminum sectional material, heat-dissipation aluminum sectional material upper surface both sides connect one piece of diffuse reflector respectively; Described aluminium base is fixed on heat-dissipation aluminum sectional material by some fixed screws.
Described lens are with the angle between 160 °-180 °.
The beneficial effect of LED backlight system described in the utility model is:
(1) by arranging lens at lamp bead surface, being conducive to making that lighting angle strengthens, uniform light, angle between 160 °-180 ° can being improved to by 120 of traditional product °, and the uniform light degree of 88% can be reached;
(2) have reflecting plate, brightness improves, and visual effect brightness increases by 30%;
(3) on whole plate face, do not have exposed electric wire, wiring board is fixed on aluminium base, be convenient to arrange, install, safety coefficient improve and attractive in appearance, all circuits only need connect from the binding post of lower end, increase or minimizing plate other circuit is not affected;
(4) use heat-dissipation aluminum sectional material not only to strengthen constant intensity, and radiating effect is fine, extends LED service life, be conducive to reducing costs.
