Abstract
The utility model relates to a flashing alarm with a light-emitting screen. A light-emitting screen (3) which replaces a low-voltage incandescent bulb is formed in a method that a circuit board (6) is welded with tens of semiconductor light-emitting chips (5) and is fixed at one side of a supporting frame (7), the other side of the supporting frame (7) is formed into a light uniforming layer (8) by synthetic resin, and the light uniforming layer (8) together with the supporting frame (7) and the circuit board (6) are encapsulated and solidified. The utility model has the advantages of long service life, uniform surface light emission, and little power consumption.
Description
The utility model is to belong to the signal alarm technology, specifically is meant signal alarm glare shield luminescence technology.
Flash alarm is used for monitoring the running status of various device, if break down the timely flashing light alarm of alarm.The flash alarm light emitting source of Chinese patent CN91215336.9 is to adopt the battery lamp bubble, and its disadvantage is to use the life-span short, about 300 hours, is hit in the transportation and easily makes the light bulb filament breakdown; Light-emitting area brightness irregularities during flashing light alarm, power consumption is big.
The purpose of this utility model is intended to design that a kind of light emitting source life-span is long, and light-emitting area brightness is even, the luminous flash alarm of the screen that power consumption is little.
The utility model is by power supply (1), control circuit (2), and luminescent screen (3), shell (4) and protective cover (5) are formed.Its purpose realizes it being to substitute the battery lamp bubble as new light emitting source with luminescent screen (3), luminescent screen (3) is the side that the wiring board (6) that is welded with dozens of semiconductor light emitting stamen sheet (5) is fixed on support (7), the even photosphere (8) that opposite side is formed by synthetic resin will be together with support (7), and wiring board (6) package curing constitutes.(7) one jiaos of apertures (9) that a trouble-signal alarm sound pilot lamp is arranged of the support of luminescent screen (3), when trouble-signal input flash alarm, the alarm sound ring, a jiao of screen is bright.If there is not trouble-signal input, sound equipment still rings, and Ping Yijiao is still bright, illustrates that this flashing light alarm sound system breaks down, because warning system is equipped with tens flash alarms, the screen angle is bright to have the sound equipment self-checking function, is convenient to operating personnel's maintenance.Support (7) is to make with engineering plastics.Power supply of the present utility model (1) output two tunnel DC current, the one tunnel for luminescent screen (3), and use for control circuit (2) on another road.Control circuit (2) is according to the alternating voltage signal of the operation conditions output " 1 " or " 0 " of monitored device, and when output " 1 " and " 0 " signal, luminescent screen (3) glistens, output " 1 ", luminescent screen (3) becomes zero diopter, and trouble-signal is eliminated, and luminescent screen puts out.
After the utility model has the advantages that adopting semiconductor light emitting stamen sheet (5) to substitute existing battery lamp steeps, be increased to 50000 hour from original average 300 hours serviceable life, life-span is long, adopt tens of semiconductor light emitting stamen sheets (5) evenly distributed on the wiring board that is fixed on support (7) (6), face is luminous just seems comparatively even for itself, the even photosphere (8) that solidify to form with resin-encapsulated again, resin to the light scatter effect under, make the whole more even light emission of luminescent screen, indication identification is more remarkable.
Fig. 1 the utility model schematic diagram
Fig. 2 the utility model light emitting screen structure figure
Semiconductor light emitting stamen sheet (5) among the utility model embodiment is arranged with about 50.What can increase or reduce according to the size of luminescent screen (3) face with to strong and weak requirement of luminescent screen (3) brightness the arrangement of semiconductor light emitting stamen sheet (5).Also can select the glow color of emitting semiconductor stamen sheet not of the same race (5) according to the characteristics of different flash alarms for use, with the luminous redness that becomes of luminescent screen (3), green, multiple color such as yellow.The power supply of the utility model embodiment (1) is to adopt flash alarm self-powered, but also can adopt the public power of warning system.Protective cover (5) is injection molded with colourless transparent plastic.
Claims (2)
1, a kind of by power supply (1), control circuit (2), the luminous flash alarm of screen that shell (4) and protective cover (5) are formed, it is characterized in that luminescent screen (3) substitutes the battery lamp bubble, luminescent screen (3) is the side that the wiring board (6) that is welded with dozens of semiconductor light emitting stamen sheet (5) is fixed on support (7), and opposite side will be formed together with support (7), wiring board (6) package curing by the even photosphere (8) of synthetic resin form.
2, the luminous flash alarm of screen according to claim 1 is characterized in that (7) one jiaos on support has the aperture (9) of an accident alarming sound equipment alarm bell pilot lamp.
