Abstract

A foam vertical luminary letter relates to a utility model that applies a LED luminescent diode on foam vertical letters so that they can radiate at night to have the effect of advertising. The LED luminescent diode (3) is arranged in a foam (1) to radiate wholly, and the LED luminescent diode (3) is arranged on the surface profile of the foam letter organic board (2) to radiate hollowly. The utility model is characterized in that: 1. the typeface is attractive because the color relies on the organic plate and the luminescent diode which has the following colors: red, yellow, blue, green, purple and the like; 2. the utility model is energy and electricity saving in that low voltage of 220 is used and no heat is produced while the LED light source is shining; 3. it is low in costs and simple to manufacture, and no special device is needed so that it is easy to popularize and spread; 4. the light source is long-lasting and the failure rate is low in that it is not destructible.

Description

The foam stereo luminous character

Technical field:

The utility model relates to the making of advertising luminous characters pattern.

Background technology:

The foam vertical letters is widely used in commercial advertisement signboard field already, and it sticks on organic plates (claiming acrylic board again) has on the certain thickness cystosepiment, presses the vertical letters pattern that the character pattern profile cut forms.Its making elegant in appearance, with low cost, easy is well received deeply.But at the environment of unglazed photograph at night, it can not be continued to see, lose due advertising effects by human eye.Literal luminescence technology at multiple night such as at present existing neon bulb, plastic uptake luminescent characters, but influence the daytime that they have literal attractive in appearancely, power consumption is big, failure rate height (referring to neon bulb); Need complete specialized equipment during the making that has, make difficulty by hand, cost height (referring to the plastic uptake word); And all do not relate to and being applied on the foam vertical letters.

Summary of the invention:

For overcoming the deficiency of luminous poor visibility not at foam vertical letters night, the utility model solves the technical scheme that its technical matters adopts: be made up of foams (1), the literal organic plates of pattern (2) and LED light emitting diode (3), each LED light emitting diode (3) head and the tail is connected in series successively, be embedded in foams (1) inside, produce the entirely lighting effect, (see that Fig. 2 and Fig. 1 a) or with LED light emitting diode (3) pin assign into the literal organic plates of pattern (2) word table facial contour, produce hollow luminous effect.(seeing Fig. 3 and Fig. 1 b) makes its electrified light emitting, still can clearly see the foam vertical letters at night, and the color of word depends on the color of organic panel and the coloured light of LED light emitting diode, and still keeps the foam vertical letters elegant in appearance by day.

Compare with literal luminescence technology at night such as neon bulb, plastic uptake luminescent characters, the beneficial effects of the utility model are: use 220 volts of low-voltages, led light source light but not heats, energy saving; With low cost, make simply, do not need complete large-scale specialized equipment, penetration and promotion easily; The led light source life-span is long, is difficult for broken the damage, and failure rate is low.

Description of drawings:

Fig. 1 is a foam stereo luminous character design sketch.A is an entirely lighting word effect, and b is hollow luminous word effect.

Fig. 2 is that light emitting diode is inlaid into the foams schematic internal view.

Fig. 3 is that light emitting diode assigns into foam word organic plates schematic surface.

Fig. 4 is light-emitting diode group connecting circuit figure.

Embodiment: the unilateral conduction of pressing light emitting diode at ordinary times is with several light emitting diode head and the tail series connection welding successively.The foam word has been carried out, seal off some ditches with thermoelectric flatiron at each stroke back side foams (1) of foam word, with the careful crooked LED light emitting diode of nose pliers (3), LED light emitting diode (3) is filled in foams (1) inside from ditch, the three-dimensional entirely lighting word of foam is promptly made.LED light emitting diode (3) heating seldom, foams (1) are not afraid of and are scorched.LED light emitting diode (3) is installed in the surperficial method of foam word organic plates (2) is, heats to led pins with the heating electric soldering iron, while hot pin is inserted in the organic plates (2), and cooling back organic plates (2) is about to LED light emitting diode (3) and fixes.The connection lead (4) of LED light emitting diode (3) penetrates foams (1), connects power supply from the word back side, and each word connects a rectifier power source (DT) separately usually.

LED light emitting diode (3) is pressed Fig. 4 circuit and is connected, and several light emitting diodes (Dn) series connection forms one group, and the quantity of diode is decided by the withstand voltage and the supply voltage of light emitting diode, generally at 120-150.Plurality of groups of LEDs (3) is connected in parallel, and inserts on 220 volts of direct currents of bridge rectifier (DT) rectification, and the group number depends on the size of character pattern.Last group light emitting diode (Dn) is if quantity is not enough, with resistance (R1) dividing potential drop, guarantees voltage on each light emitting diode in rated voltage (1.5V-2.5V) scope, and makes its brightness consistent with the brightness of other group.(R2) be current-limiting resistance in the circuit, protection LED light emitting diode (3) is not subjected to rush of current.(R1) resistance to 50 kilohms, (R2) is 1 watt 1-2 kilohm resistance at thousands of ohm.

Claims

1, a kind of foam stereo luminous character, form by foams (1), the literal organic plates of pattern (2) and LED light emitting diode (3), it is characterized in that: each LED light emitting diode (3) head and the tail is connected in series successively, be embedded in foams (1) inside, perhaps LED light emitting diode (3) pin assigned into the literal organic plates of pattern (2) word table facial contour.
