Abstract
The utility model relates to an assembled lens spotlight type luminous diode lattice display. Luminous diode chips are arranged in lattice on a circuit base plate and external wires are led out. Refraction cavity holes are mounted on the circuit base plate, which are respectively corresponding to each luminous pixel point and are sealed by a plurality of epoxy resin convex glasses. The convex glasses are one-to-one corresponding to each luminous diode chip in the refraction cavity holes, and the light emission angle of the luminous diode chip is adjusted by the curvature of the convex glass and the projecting height of the convex glass. The utility model is characterized in that each luminous pixel is formed by a plurality of convex glasses according to the number of the luminous diode chips, and each chip is positioned on the center position of each convex glass, thereby realizing the favorable mixed color effect of each chip. And the utility model is sealed in lattice, which can improve the unit area pixel density of an outdoor display, increase the clearness of pictures, reduce the cost, and improve the functions.
Description
Technical field
The utility model belongs to indicating device or the circuit engineering field that shows variable information with quiescent processes, is specifically related to a kind of electronic color display of making light source of diode.
Technical background
Light-focusing type LED array display of the prior art, usually by circuit base plate, the shell of light-emitting diode chip for backlight unit that dot matrix is arranged and band reflection cavity is formed, and each reflection cavity shell is sealed by formed in mould epoxy resin convex lens.It overcomes the deficiency of flat-panel screens, the luminous intensity height, and the optically focused performance is good.If but in a pixel encapsulation a plurality of different colours light-emitting diode chip for backlight unit, because each chip position departs from same convex lens, can not keep the parallel of normal, therefore the vision acceptor is very big at the aberration of different coloured light that angle is experienced, and the colour mixture effect of a plurality of chips is bad in the same pixel.
The utility model is at the prior art above shortcomings, purpose is to provide a kind of each light emitting pixel point being made up of a plurality of convex lens according to what of light-emitting diode chip for backlight unit, and make each chip all be in the center of each convex lens, thereby realize the lens combination converged LED array display of the colour mixture effect that each chip is good.
Summary of the invention
A kind of lens combination converged LED array display, it has a circuit base plate, dot matrix arranging light emitting diode chip on the circuit base plate, and draw outer lead, circuit base plate is provided with the shell of band reflection lumen pore, and each reflects respectively corresponding each the light emitting pixel point of lumen pore.Respectively reflecting on the lumen pore by a plurality of epoxy resin convex lens sealings of described shell, convex lens are corresponding one by one with each light-emitting diode chip for backlight unit in the reflection lumen pore, by the curvature of convex lens and the light emission angle of protrusion height adjusting light-emitting diode chip for backlight unit.
Adopt the following advantage that the utlity model has of said structure:
1. corresponding convex lens of each chip both can improve the luminosity of each pixel, can solve the inconsistent problem of each chip light emitting colour mixture angle of same pixel again.
2. owing to adopt the form of dot matrix encapsulation, be different from general outdoor display screen light-emitting component: as lightening tube etc., and can significantly reduce the diameter of each light emitting pixel, thereby the light emitting pixel density (picture element density than lightening tube improves 2.5-6.5 doubly, even higher) that improves the outdoor display screen unit area greatly strengthens image sharpness.Also can simplify the manufacture craft of outdoor display screen, reduce cost greatly, improve function.

Fig. 1 is the side view of this lens combination converged LED array display;
Fig. 2 is the sectional view of this lens combination converged LED array display;
Fig. 3 is the planimetric map of this lens combination converged LED array display.
Embodiment
As depicted in figs. 1 and 2, the bottom of lens combination converged LED array display is a circuit base plate 5, dot matrix arranging light emitting diode chip 4 on it, and draw outer lead 3.Cover one plastic casing 2 on the circuit base plate 5, plastic casing 2 dot matrix are established 6, four light-emitting diode chip for backlight unit of reflection lumen pore 4 and are constituted a light emitting pixel point, and reflection lumen pore 6 is corresponding one by one with each light emitting pixel point that dot matrix is arranged.Each reflects on the lumen pore 6 by 1 sealing of four epoxy resin convex lens again, and interior each light-emitting diode chip for backlight unit 4 of epoxy resin convex lens 1 and reflection lumen pore 6 is corresponding one by one, forms a complete display thus.The light intensity of light emitting pixel point and angle can be adjusted the curvature and the height of projection of epoxy resin convex lens 1 and control when sealing.
Can encapsulate the light-emitting diode chip for backlight unit of a plurality of different colours in each light emitting pixel point of the present utility model as required.
