Abstract
The utility model discloses a magnetic absorption-type light-emitting device which comprises a transparent shell (1), and a printed circuit board (3) arranged inside the transparent shell (1) and provided with a light-emitting element (2), and also comprises positive and negative magnetic material strips (4) communicated with a power supply; and the back side of the printed circuit board (3) is provided with positive and negative magnets (5) connected with the printed circuit board and respectively and correspondingly connected with the positive and negative magnetic material strips (4) by magnetic absorption at intervals. After two iron bars are electrified, an LED inside a letter of the transparent shell is electrified and emits light and displays a character or a pattern. When the character or the pattern needs to be changed, only a character unit needs to be moved and recombined and then magnetically absorbed on the positive and negative magnetic material strips, thus being very convenient. The flexible detachable connection causes the maintenance to be simple and the packaging and transportation to be convenient.
Description
Technical field
The utility model relates to LED luminescent characters signboard starter gear is installed, and relates in particular to a kind of light-emitting device that is used for indoor displaying advertisement.
Background technology
Along with science and technology and The development in society and economy, increasing information is propagated by variety of way.Transmit the traditional approach of information by all kinds of LED signboards, because it is attractive in appearance, eye-catching and be convenient to be located at the big region of medium acceptor flow, thereby lasting.The circuit connection complexity of original LED luminous pattern and literal needs the professional to install.After the installation, literal just can not arbitrarily move, more impossible fractionation and the recombinant that literal is replaced or carry out literal.If there is a literal to open circuit in addition in its Circuits System, then all literal need whole dismounting just can carry out maintenance and inspection, and the maintenance in later stage is very loaded down with trivial details.Its original serial connection mode has also caused packed and transported inconvenience or the like problem.
Summary of the invention
The utility model is in order to solve the problems of the technologies described above, but proposes a kind of arbitrary combination, magnetic-type light-emitting device easy to maintenance.
For solving the problems of the technologies described above, the technical solution of the utility model is a kind of magnetic-type light-emitting device of structure, comprises transparent shell, is located at the printed circuit board (PCB) that has light-emitting component in this transparent shell.Also comprise the positive and negative electrode magnetic material strip that is communicated with power supply; The back side of described printed circuit board (PCB) is interval with the positive and negative electrode magnet that is electrically connected with P.e.c. and be connected with the corresponding magnetic of described positive and negative electrode magnetic material strip difference.
Preferred version of the present utility model, described transparent shell can be rearranged by a plurality of independently figures and/or text unit.
Another preferred version of the present utility model, described transparent shell also can be made up of single figure and/or literal.
The utility model adopts circuit and the power connection of magnetic-type syndeton with neon bulb luminous pattern and literal.This is a kind of removable flexibly connection, and figure, text unit can arbitrarily move, and promptly figure, text unit can be replaced or carry out the fractionation and the recombinant of literal.If there is a literal to open circuit in addition in its Circuits System, do not need whole dismounting to carry out maintenance and inspection, safeguard very simple.Packed and transported is also very convenient.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is described in detail, wherein:
Fig. 1 is the assembling synoptic diagram of the utility model preferred embodiment;
Fig. 2 is the synoptic diagram of positive and negative electrode iron bar among Fig. 1;
Fig. 3 is the synoptic diagram at Fig. 1 letter back side.
Embodiment
As shown in Figure 1, be the basic structure of the utility model preferred embodiment, described magnetic-type light-emitting device comprises transparent shell 1, is located at the printed circuit board (PCB) that has light-emitting component 23 (consulting Fig. 3) in this transparent shell.Also comprise the positive and negative electrode magnetic material strip 4 (consulting Fig. 2) that is communicated with power supply.The back side of printed circuit board (PCB) 3 is provided with the positive and negative electrode magnet 5 that is electrically connected with P.e.c..These positive and negative magnet connect with described positive and negative electrode magnetic material strip 4 respectively corresponding magnetic.In this example, positive and negative electrode magnetic material strip 4 also can adopt the magnetic material of other conductions to make by the iron bar material, as, material such as steel bar, nickel bar.The light-emitting component 2 that printed circuit board (PCB) 3 has is LED.And transparent shell 1 by four independently the letter " OPEN " rearrange.In addition, transparent shell 1 also can be made up of a plurality of independently figures or character arranging, perhaps is made up of a plurality of independently figures and character arranging.In addition, transparent shell 1 can also be made up of single figure and/or literal.Magnet 5 is connected the effect that can play switch in fact with the magnetic of magnetic material strip 4, and promptly when magnet 5 and magnetic material strip 4 are separated, circuit just disconnects, the figure and the literal of maintenance that can be safe or replacing transparent shell 1.Certainly, the magnetic connection also can be provided with conversely, promptly at the back side of printed circuit board (PCB) 3 the positive and negative electrode piece of magnetic material that is electrically connected with P.e.c. is set, and the positive and negative electrode magnetic material strip that will be communicated with power supply is arranged to magnetic stripe.Setting also can be finished function of the present utility model like this, but effect is not good enough, cost is higher.
During actual the use, be positive and negative electrode magnetic material strip 4 secured in parallel that will be communicated with power supply in wall, according to the arrangement requirement that designs, letter (or figure etc.) is magneted on the positive and negative electrode magnetic material strip 4 and (consults Fig. 1).After two magnetic material strips energisings, the inner LED of letter will electrified light emitting and show literal or figure.If when need changing literal or figure, only need with text unit move reorganization be magneted in again on the positive and negative electrode magnetic material strip just can, very convenient.This removable flexibly connection makes and safeguards simply that packed and transported is also convenient.
