Abstract

The utility model discloses a plate shell, which is a convexity transparent LED dot matrix module, relating to a combination mode of the matrix and a structural shape of the plate shell. The utility model is composed of a plate shell, a Double-Sided circuit board and a luminous diode chip. The facade of the Double-Sided circuit board is provided with a plurality of white reflecting surface to shape a dot matrix, the distances between the center latitudinal and longitudinal direction of the matrix are equal; the place except the white reflecting surface is coated with black; a LED chip is affixed on the reflecting surface; the plate shell is a dot matrix convexity transparent cover, and is shaped a same dot matrix by the light gathering heads which has the same number with the reflecting surface; the shape of the spot light head is corresponding to that of the reflecting surface, that is solid of squareness, or roundness or ellipse. The utility model has the advantages of excellent visual effect, low extraneous light interference on brightness and low cost. The utility model has a wide application because of the high cost performance.

Description

A kind of plate shell is the transparent LED lattice module of convex

Technical field

The utility model relates to the LED lattice module, specifically, relates to the array mode of module and the planform of plate shell thereof.

Background technology

LED (light emitting diode) lattice module can replace charactron, symbol pipe and rice word pipe; Not only can display digit, also can show all letter words and symbol.If, can constitute big screen display screen with polylith combination, be used for the demonstration of Chinese character, figure, chart etc., be widely used in the occasions such as indication, explanation, advertisement of airport, station, harbour, bank and many public places.

Existing LED lattice module generally is made up of plate shell, double-sided wiring board, led chip.The plate shell is a kind of square plastic plate, and the dot matrix reflection hole (as 5 * 5,8 * 8 etc.) of recessed proper alignment is arranged on the plate shell, the center of Kong Yukong its in length and breadth between distance equate that the planform of reflection hole determines the shape of luminous bright spot; Be double-sided wiring board below the plate shell, the reverse side of double-sided wiring board is connected with integrated circuit and pin for connection; The center fixation of the front of double-sided wiring board and reflection hole bottom has led chip, and the back that powers on is luminous.

Existing LED lattice module, its shortcoming are that vision is little, and brightness is subjected to the interference of external light bigger.

Along with the progress of society, along with the raising of living standards of the people and esthetic sentiment, require good visual effect such as the shown Chinese character of big screen display screen, figure, chart, pleasing.

Also require to reduce production costs as the manufacturer.

Summary of the invention

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect that existing LED lattice module exists, and is the transparent LED lattice module of convex and a kind of plate shell is provided.

The purpose of this utility model is achieved in that and identical with above-mentioned existing LED lattice module is: form by plate shell, double-sided wiring board, led chip; Different is: on the existing plate shell recessed dot matrix reflection hole is arranged; This plate shell is a kind of dot matrix convex translucent cover.Its described " convex ", or be square convex, or be circular convex, or be oval convex; Its described " transparent ", or colourless, or coloured (red, orange, yellow, green, blue or green, blue, purple).

The utlity model has following advantage and good effect:

1. because " convex " promptly has the convex lens effect, make good visual effect, be subjected to the interference of external light little, good brightness.Specifically, square convex makes good visual effect; Circular, oval convex makes and is subjected to the interference of external light little, good brightness.

2. therefore the plate shell is produced easily by transparent resin material moulded section, and cost reduces significantly.

In a word, the utility model ratio of performance to price height had wide application prospect.

Embodiment

The utility model is made up of plate shell 1, double-sided wiring board 2, led chip 3; On the reverse side 2.2 of double-sided wiring board 2, be connected with integrated circuit and pin for connection;

As shown in Figure 1, on the front 2.1 of double-sided wiring board 2, form dot matrix by some white reflectings surface 4, its center in length and breadth between distance equate; The shape of reflecting surface or is circular on demand or be square, or be ellipse.The place is coated with full black beyond the white reflecting surface 2; Because in sharp contrast, contrast is big, makes illumination effect good.On reflecting surface 4, be pasted with led chip 3.

By Fig. 2,3,4 as can be known, plate shell 1 is a kind of dot matrix convex translucent cover, by forming same dot matrix with the optically focused head of reflecting surface 4 same numbers; The shape of optically focused head is corresponding with the shape of reflecting surface 4, and is promptly three-dimensional or be square, or be circle, or is ellipse.
