Description

LED curtain screen unit piece

Technical field

The utility model relates to the decorative lighting technical field, and especially a kind of LED curtain screen unit piece is particularly suitable for large-screen and decorates use.

Background technology

The luminous component of LED display is to be assemblied to form by LED (being light emitting diode), its advantage is that power consumption is few, brightness is high, at the bottom of the WV, drive simple, the life-span is long, stable performance, be used widely in a lot of places.In the prior art, large display screen is to be assembled by many unit piece, by the decoration corporation that respectively bears engineering design cell piece voluntarily; Mainly by underframe, wiring board, LED lamp and face shield, it is not of uniform size, and architectural feature is different; Generally all pass through optimal design, the ubiquity unreasonable structure, the dress folding is inconvenient; Connect insecure and be not easy weak point such as manufacturing, therefore on promoting, still have significant limitation.

The utility model content

The purpose of the utility model is to solve the problems referred to above that existing LED curtain screen unit piece exists, and provides a kind of structural strength good, and the dress folding makes things convenient for accumulating easily, the LED curtain screen unit piece that is connected firmly.

Above-mentioned task realizes by this way; A kind of LED curtain screen unit piece includes base plate, wiring board, LED lamp and face shield, it is characterized in that: described base plate is one and is provided with 6 ~ 14 row LED lamps from top to bottom; Every row lays 12 ~ 24 LED lamps; Spacing between each LED lamp is 8 ~ 16 millimeters a support plate, on the base plate between two the LED lamps in base plate both sides, upper end, respectively is provided with an outwards clasp of protrusion, on the base plate between two corresponding LED lamps of both sides, base plate lower end, respectively is provided with an interior concane gap; In breach, be provided with a coupling shaft with the clasp snapping, respectively be provided with an engaging lug with holes in the both sides of base plate.

Such scheme also can take following measure further perfect.

Described base plate is to lay 8 row LED lamps, and every row is provided with 16 LED lamps, and it is suitable that the spacing of each LED lamp is 12 millimeters.

On the plate face between the every row of base plate intermediate power supplies and the signal connector inner chamber both sides LED lamp, have the ventilation and heat slotted hole, on the face shield of correspondence, also be provided with onesize ventilation and heat slotted hole.So that help the heat radiation of LED lamp.

Described clasp is that an opening is a clasp wide outside and narrow inside, that endoporus is a circle, Open Side Down.

The cross sections of described coupling shaft is a cydariform, and its arc surface external diameter equates with clasp endoporus internal diameter, two sections and plate face balance, and its thickness equates with the slot width of clasp opening.When two pieces connected, first clasp opening with a piece turn 90 degrees and is in horizontality, and the coupling shaft of aiming at another piece then is inserted in the coupling shaft; Go back to horizontal level again, this moment, two cheap levels of piece linked together, and the endoporus of clasp engages with the coupling shaft arc surface; Very link together securely, can not skid off, only if just wherein a piece go to 90 degree and can deviate from; Otherwise can't break away from, thereby improve the security of using widely.

The utility model is to use like this; During use; LED curtain screen unit piece is turn 90 degrees, let its clasp aim at the coupling shaft of another piece LED curtain screen unit piece, turn over after being inserted in the coupling shaft and turn 90 degrees; Let two LED curtain screen unit pieces horizontally connect together; So analogize, just can polylith LED curtain screen unit piece be linked together up and down, and then with the engaging lug with holes of each LED curtain screen piece both sides, unit of steel wire penetrating it is connected in series and just can constitutes the very big LED display of a width of cloth.

The utility model beneficial effect is following: visible from the structure and the operating position of the utility model, the utility model dress folding is convenient and swift, is connected firmly; Be not easy to come off; Can make up with the shape and the concavo-convex variation of ladder of wall, very big adaptability and dirigibility arranged, in addition; The new shape of this practicality also has simple and practical, advantage such as makes and easy to utilize easily.
