Abstract

The utility model discloses a variable message sign by the adoption of LED modules for direct postback of single-point detection data. The variable message sign is characterized in that the variable message sign is mainly composed of a mark scan card (1) and more than one LED module; all the LED modules are connected to each other through pins; and the mark scan card (1) is connected to the first row of LED modules (2) through flat cables (3). The variable message sign provided by the utility model breaks through conventional limit of traditional LED modules by cooperation between long flat cables and a single-point detection board for pixel detection. According to the variable message sign, 14 pins are directly arranged on the LED modules so as to carry out data postback. Thus, usage amount of the flat cables is reduced to the maximum, and stability of the LED modules is raised greatly.

Description

A kind of LED of employing module directly returns the changeable-message sign that single-point detects data
Technical field
The utility model belongs to LED field of traffic, specifically refers to that a kind of LED of employing module directly returns the changeable-message sign that single-point detects data.
Background technology
LED lamp is the most frequently used a kind of electrical lighting elements of current people, and because it has low in energy consumption, stable performance and the feature such as volume is little, therefore, it has been widely used in various changeable-message signs.The GB 23826-2009 standard that country promulgates has proposed concrete strict regulations to the detection of LED module light emitting pixel.At present, common the adopted detection method of people is, last row's module of screen body is detected by single-point check-out console, then the data of this detection returned to minute to sweep card and process.Because the needed winding displacement of LED module is not only a lot, and very long, therefore can cause the stability of LED module poor, the wiring in casing also has difficulties.Meanwhile, very long to the winding displacement of minute sweeping card owing to connecting single-point check-out console, so line drop is larger, make single-point detect can carry out, and just must improve voltage, thus the insulating property of equipment are required just higher, can great increase cost of manufacture.
Utility model content
Poor, the difficult wiring of existing LED module performance when the purpose of this utility model is to overcome current LED module light emitting pixel and detects, and the defect higher to insulating requirements, provide a kind of simple in structure, the employing LED module that can effectively overcome above defect directly returns the changeable-message sign that single-point detects data.
The purpose of this utility model is achieved through the following technical solutions: a kind of LED of employing module directly returns the changeable-message sign that single-point detects data, mainly by dividing, sweep card, and formed by more than one LED module, and all by contact pin, interconnect between all LED modules; Within described minute, sweeping cartoon crosses winding displacement and is connected with first row's LED module.
In order better to realize the utility model, on each LED module, be equipped with 14 pins and 14 pin holes.
The utility model is compared and is had the following advantages and beneficial effect compared with prior art:
(1) the utility model has been broken through traditional LED module and with long winding displacement and single-point check-out console, has been used in conjunction with to carry out the routine restriction of pixel detection, 14 contact pins are directly set on LED module, with this, carry out data passback, thereby farthest reduced the use amount of winding displacement, improved greatly the stability of LED module.
(2) the utility model does not need to re-use single-point check-out console, has not only saved hardware cost, makes circuit more succinctly attractive in appearance, and can also save installation time.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Reference numeral name in above accompanying drawing is called:
1-minute sweep card, 2-LED module, 3-winding displacement.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, the quantity of LED module 2 of the present utility model is more than one, and can be combined into arbitrary shape according to actual conditions, as rectangle, square or circular etc.
In order to improve the stability of LED module 2, reduce the use amount of winding displacement, the utility model is equipped with 14 pins and pin holes on each LED module 2.Between every two adjacent LEDs module 2, by contact pin, interconnect, with this, just LED module 2 can be connected in series.Minute sweep card 1 and by winding displacement 3, be connected with first row's LED module 2, divide and sweep 1, card and need to pass through winding displacement 3 and be connected with the first LED module 2 of the LED module 2 being connected in series.
By with upper type, any 4 passages that the utility model just can make full use of on 14 passages of LED module 2 carry out the passback that single-point detects data, thereby overcome the existing various defects of traditional approach.
As mentioned above, just can well realize the utility model.

Claims (2)

1. adopt LED module directly to return the changeable-message sign that single-point detects data, it is characterized in that: mainly by dividing, sweep card (1), and formed by more than one LED module (2), and all by contact pin, interconnect between all LED modules (2); Within described minute, sweeping card (1) is connected with first row's LED module (2) by winding displacement (3).
