Abstract

The utility model relates to an electronic fire indicator which consists of a substrate board and a lighting device and is characterized in that the substrate board is transparent organic glass and grooves with words and patterns are opened at the surface of the substrate according to indicating contents and the interior of the groove is painted with colored paint or covered with a reflecting film; a group of embedded LEDs are arranged at the periphery of the substrate board which is attached with a colored plastic film frame. The device has the advantages of easy production, low cost, low power consumption, planarization, long service life, convenient maintenance, higher brightness and convenient word and pattern making, etc.

Description

Light emitting diode-organic glass photoconduction fire-fighting electronic indicator

Technical field

The utility model relates to a kind of safety instruction board.

Background technology

At present, the major part of using in skyscraper " fire-fighting electronic indicator " is the dull and stereotyped indicator of soft screen electroluminescence (EL).It is a kind of to show that fire prompting literal, figure are the panel display of content.This display exists following shortcoming: the one, provide the interchange high-frequency electrical with converter power supply, and make really panelized of display, its thickness and is prone to electric spark more than 5CM, and voltage is higher, generally more than 100V; The 2nd, brightness is low, generally below 10cd/m2; The 3rd, under high frequency, to work, the life-span is short, and brightness just obviously descends after 1 year.

Summary of the invention

The utility model can be realized the effects such as panelized, low-voltage power supply, comparatively ideal brightness and life-span length of notice board.

Electronic director described in the utility model is made up of substrate and lighting device; It is characterized in that: described substrate can be made up of transparent engineering plastics or organic glass; Need scribe by suggestion content on its surface or mould suppresses the groove of standard compliant safety instruction literal, figure; Described groove corner is two seamed edge corner structures; In described groove, scribble colour-wash or dyestuff, or card there is the colorful film with certain transparency with certain transparency; In described groove, also can colored glass microbead reflecting film be arranged card; Be distributed with edge in described substrate periphery by certain distance and advance some light emitting diodes of substrate and the assembly that current-limiting resistance is formed, and on the substrate periphery card colored plastic sheeting frame.

Fire-fighting electronic indicator provided by the utility model has easy production, cost is low, power consumption is little, panelized, the life-span is long, easy to maintenance, brightness is higher and make advantages such as literal, figure be convenient.

Description of drawings

Fig. 1 is the structural representation of fire-fighting electronic indicator described in the utility model;

Fig. 2 is the groove schematic cross-section of fire-fighting electronic indicator described in the utility model;

Fig. 3 is that the substrate periphery of fire-fighting electronic indicator described in the utility model is bumped into the light emitting diode construction synoptic diagram;

Assembly numbering explanation in the accompanying drawing: the 1st, substrate, the 2nd, the band colored plastic film frame, the 3rd that substrate periphery is pasted, light emitting diode, the 4th, substrate recess, the 5th, band color paint or film, the 6th in the groove, the double edge angle structure of substrate recess.

Embodiment

Carve the groove 4 of certain depth on the surface of organic glass, these grooves 4 also can form with the mould compacting when substrate 1 is made.Described groove 4 is grapholect, foreign letter, graphics shape by country's promulgation.Peripheral lateral surface at substrate 1 is distributed with the light emitting diode 3 that is bumped into substrate 1 by certain distance.The periphery of substrate 1 also posts the band colored plastic film frame 2 of hiding described light emitting diode 3 usefulness.The corner of described groove 4 is two angular structures 6, and groove scribbles for 4 li and has color, coating or dyestuff 5 with certain transparency.If this device in outdoor application, posts colored glass microbead reflecting film in the groove 4, can adopt the 3M product of General Corporation.

Because this device power consumption and voltage are low, outdoor can be preferably and the solar cell adapted, not only be applicable to Fire Alarm, also can be used for other notice board, as the building doorplate etc.

Claims

1. light emitting diode-organic glass photoconduction fire-fighting electronic indicator, it is characterized in that: described substrate can be made up of transparent engineering plastics or organic glass; Need scribe by suggestion content on its surface or mould suppresses the groove of standard compliant safety instruction literal, figure; Described groove corner is two seamed edge corner structures; In described groove, scribble colour-wash or dyestuff, or card there is the colorful film with certain transparency with certain transparency; In described groove, also can colored glass microbead reflecting film be arranged card; Be distributed with edge in described substrate periphery by certain distance and advance some light emitting diodes of substrate and the assembly that current-limiting resistance is formed, and on the substrate periphery card colored plastic sheeting frame.
