Abstract
The utility model discloses an LED (light-emitting diode) display device which is characterized by comprising a circuit board, a light transmission film and a light blocking layer, wherein the light transmission film, the light blocking layer and the circuit board are sequentially arranged from top to bottom; the circuit board is in circuit connection with an LED lamp and a control chip which controls the LED lamp to emit light synchronously with music; light transmission patterns are printed on the light transmission film, and the part on the light transmission film only with the light transmission patterns is light-transmitting; the light blocking layer is internally provided with a hollow light blocking groove; and the light blocking groove corresponds to the LED lamp on the circuit and the light transmission patterns on the light transmission film in position. The LED display device provided by the utility model has the advantages of small energy consumption, energy conservation, environment friendliness and low production cost.
Description
Technical field
The utility model relates to scale display device technical field, is a kind of technology that is used for the LED display device of scale display module specifically.
Background technology
In daily life; The equipment of playing back music such as common audio amplifier, radio; On equipment, all be provided with a scale display surface, it can rise and fall according to the height of volume, and perhaps the speed of speed changes optical screen; Let Music Appreciation person when enjoy music is brought, also can obtain satisfying of vision.The scale display module at initial stage is to use versicolor light-emitting diodes light to show; This equipment integral is all more coarse; And the serviceable life of two aurora is generally all shorter; If equipment has been grown service time, some two aurora can damage, and will influence the normal display effect of scale display module like this.Afterwards, people had invented fluorescence radiation again, and were luminous by it through the high pressure excitated fluorescent powder, and this light-emitting mode can make pattern luminous through phosphor pattern is set, and can let illumination effect more optimize, but manufacturing cost is higher, and very power consumption.
Summary of the invention
The purpose of the utility model provide that a kind of energy consumption is low, production cost is low the LED display device.
Realize through following technical scheme below:
A kind of LED display device; It is characterized in that: said LED display device comprises circuit board, light-transmissive film, separated photosphere; Light-transmissive film, separated photosphere and circuit board set gradually from top to bottom; Circuit is connected with the control chip of LED lamp, control LED lamp and music synchronous light-emitting on circuit board; The position of printing opacity pattern printing opacity is only arranged being printed on the light-transmissive film on printing opacity pattern and the light-transmissive film, at separated the light groove that in photosphere, is provided with hollow, the position of separated light groove is corresponding to LED lamp on the circuit and the printing opacity pattern on the light-transmissive film.
Said control chip is controlled the quantity that LED opens according to the rhythm of music.
The utility model compared with prior art has the following advantages.
The utility model is owing to stamp corresponding printing opacity pattern on light-transmissive film, and makes printing opacity pattern relevant position light-permeable, other position shadings; And the separated light groove in photosphere is a hollow, and the position is corresponding to LED lamp on the related circuit and corresponding printing opacity pattern, when LED is luminous; Light can be collected the corresponding printing opacity pattern of directive by the wall at a distance from the light groove, makes the pattern printing opacity luminous, simultaneously; Through the program on the circuit board; Can realize that LED follows music synchronous, control the quantity that LED opens, thereby on light-passing board, realize the scale effect according to the rhythm of music.This shows that the utility model energy consumption is low, energy-conserving and environment-protective, and also production cost is low.

Fig. 2 is the utility model LED display device light-transmissive film structural representation;
Fig. 3 is that the utility model LED display device is at a distance from the photosphere structural representation;
Fig. 4 is the utility model LED display device board structure of circuit synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model LED display device is described in further detail.
Shown in Fig. 1-4; The utility model LED display device; Comprise circuit board 1, light-transmissive film 3, separated photosphere 2, also be reflection shield or reflective plastic plate at a distance from photosphere 2, light-transmissive film 3, separated photosphere 2 and circuit board 1 set gradually from top to bottom; Circuit is connected with the control chip of LED lamp 11, control LED lamp and music synchronous light-emitting on circuit board 1; The position of printing opacity pattern printing opacity is only arranged being printed on the light-transmissive film 3 on printing opacity pattern 31 and the light-transmissive film, at separated the light groove 21 that in photosphere 2, is provided with hollow, at a distance from the position of light groove 21 corresponding to the printing opacity pattern 31 on LED lamp on the circuit 11 and the light-transmissive film.Wherein control chip rises and falls according to the height of the rhythm of music or volume and controls the quantity that LED lamp 11 is opened.When LED lamp 11 is luminous; Light can be collected the corresponding printing opacity pattern of directive by the wall at a distance from the light groove, makes the pattern printing opacity luminous, simultaneously; Through the control chip on the circuit board; Can realize that LED lamp 11 is synchronous with music, control the quantity that LED lamp 11 is opened, thereby on light-passing board, realize the scale effect according to the rhythm of music.
Claims (2)
