Abstract
The utility model discloses a LED dot-matrix module having highly effective reflection hole; the utility model relates to a LED dot-matrix module consisting of a packaging shell 1, a copper clad laminate 2, a double-sided circuit board 3 and a LED chip 4; the copper clad laminate 2 is arranged under the packaging shell 1; the double-sided circuit board 3 is arranged under the copper clad laminate 2; a dot-matrix consisting of a white catopter 3.1.1 is arranged on a right side 3.1 of the double-sided circuit board 3; the LED chip 4 is arranged on the white catopter 3.1.1; the copper clad laminate 2 is a square epoxide resin plate with black copper film covering on the right side; a sunken dot-matrix reflection hole 2.1 corresponding to the LED chip 4 is arranged on the copper clad laminate 2; a white reflection film 2.1.1 is covered on the surface of the reflection hole 2.1; the white reflection film 2.1.1 is tin film, silver film, aluminum film or platinum film. As the white reflection film is covered on the surface of the reflection hole, reflectivity is high and visual effect is good; as the copper film is covered on the right side of the copper clad laminate, the LED chip radiates evenly.
Description
Technical field
The utility model relates to a kind of LED lattice module, specifically, relates to a kind of LED lattice module that efficient reflection hole is arranged.
Background technology
LED (light-emitting diode) lattice module can replace charactron, symbol pipe and rice word pipe; Not only numeral can be shown, also all letter words and symbol can be shown.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 front of double-sided wiring board is that the center fixation of reflection hole bottom has led chip, and the back that powers on is luminous.
Existing LED lattice module, its shortcoming is: reflection hole is the part of plate shell, is a kind of white plastic goods, reflectivity is low, poor visual effect.
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.
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 a kind of LED lattice module that efficient reflection hole is arranged is provided.
The purpose of this utility model is achieved in that
Identical with above-mentioned existing LED lattice module is: form by plate shell, double-sided wiring board, led chip;
Different is: the plate shell is divided into two into encapsulating shell and copper-clad plate.
Copper-clad plate and double-sided wiring board are worked to fix, encapsulate in encapsulating shell areflexia hole.Copper-clad plate is the square epoxy resin board plate that a kind of front is coated with the black copper film, and the dot matrix reflection hole of recessed proper alignment is arranged on it, 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; At the surface coverage adularescent metal film of reflection hole, as the high tin film of reflectivity, silverskin, aluminium film, platinum film etc.At the back side of copper-clad plate is insulating surfaces, can not cause the short circuit of the double-sided wiring board below it.
The utlity model has following advantage and good effect:
1. because the surface coverage adularescent metal film of reflection hole, reflectivity height, good visual effect;
2. because the front of copper-clad plate is coated with copper film, make the led chip heat radiation evenly.

2-copper-clad plate, 2.1-reflection hole, 2.1.1-reflectance coating;
3-double-sided wiring board, 3.1-front, 3.2-reverse side;
4-led chip.
Embodiment
Further specify below in conjunction with drawings and Examples.
The utility model is made up of encapsulating shell 1, copper-clad plate 2, double-sided wiring board 3, led chip 4; At encapsulating shell is for 1 time copper-clad plate 2, is for 2 times double-sided wiring board 3 in copper-clad plate, on the front 3.1 of double-sided wiring board 3, forms dot matrix by white reflecting surface 3.1.1, and led chip 4 is arranged on reflecting surface 3.1.1;
Copper-clad plate 2 is square epoxy resin board plates that a kind of front is coated with the black copper film, and the recessed dot matrix reflection hole 2.1 corresponding with chip 4 positions arranged on it; Surface coverage adularescent reflectance coating 2.1.1 at reflection hole 2.1.
The utility model operation principle is as follows: luminous after led chip 4 powers on, through the efficient reflection of the white reflection film 2.1.1 of reflection hole 2.1, produce the visual effect that is better than existing LED lattice module.
