Description

Escape way uses luminous license plate

The utility model belongs to a kind of luminous sign board, is mainly used in escape way.

All escape ways are provided with sign board now, but this sign board effect on daytime is apparent in view, when night of ambient light illumination difference or overcast and rainy foggy days, these sign boards have lost due effect, escape way was arranged originally, owing to can't see any sign and come reminds people evening, make the people feel dangerous on the contrary.

The purpose of this utility model provided in the night and overcast and rainy foggy days of a kind of daytime and poor visibility, a kind of escape way that the effect of sign board can both be given full play to uses luminous license plate, making it is benchmark with Fire Exit Signs board content, can both be high-visible in one day twenty four hours.

This purpose realizes with following technical proposal: panel, base plate that it includes sign board reach side plate all around, between panel and base plate, be provided with the camber reflection plate, base plate is provided with the photoelectric control circuit plate, side plate is provided with light and shows circuit board, described panel is two-layer up and down, the upper strata hollow out has " escape way " and floor printed words, and Decorative frame is arranged around the panel; Described light-operated circuit is by power circuit, be serially connected with light-operated driving circuit successively in its output, on-off circuit constitutes, output serial connection light inlet at on-off circuit shows circuit and forms light-operated display circuit, and the output at power circuit is serially connected with online back-up source in addition.Described power circuit is by high-voltage alternating electric capacity C, and the bridge rectifier circuit that step-down current-limiting circuit that resistance R constitutes and diode D1～D4 constitutes is formed; Online power backup circuit is by rechargeable battery E and stabilivolt WC and connects and form.Light-operated driving circuit is the sample circuit that is made of photoresistance RL, and bleeder circuit and triode BG1 amplifying circuit that resistance R 1, RL constitute are formed.On-off circuit is made up of with switch triode BG2 inclined to one side value resistance R 2.It is by a group light emitting diode L1, L2, L3 that described light shows circuit ... the square formation network that the mutual connection in series-parallel of L24 constitutes and forming.

This sign board, monnolithic case is elegant in appearance, is furnished with corresponding color, and the sign board content is along with the big or small automatic luminous demonstration of ambient light illumination.Have online back-up source in the sign board light-operated circuit, can be after the power failure along continuous work 10 hours.The simple power consumption of one-piece construction is little, and power consumption is about the 0.5 degree/moon.

Describe one-piece construction of the present utility model and principle of work thereof in detail in conjunction with following accompanying drawing:

Fig. 1 is the utility model front view.

Fig. 2 takes down left view behind the left plate for the utility model.

Fig. 3 is light-operated display circuit block diagram.

Fig. 4 is light-operated display circuit fundamental diagram.

As shown in Figure 1, 2, this escape way uses luminous license plate to have panel 1, base plate 2, side plate 3 arranged all around.Between panel and base plate and near base plate, be provided with camber reflection plate 4.Photoelectric control circuit plate 5 is arranged on the base plate, and light shows the inboard that circuit board 6 is arranged on side panel.Panel 1 is two-layer up and down; The upper strata hollow out has " escape way " and floor printed words 8, is provided with Decorative frame 9 around the panel 1.On base plate, also be provided with mounting hole 7.Panel 1 can add the compound injection molded with the AS engineering plastics, the upper strata color can be Lan Se or redness, doorplate content (escape way, Stall) is carved by engraving machine, literal behind the engraving is shown by panel lower floor color, the milky that is translucent, surperficial blue look (or red) background sets off the milky literal, and daytime is clear easily debates, when night or environment low visibility, sign board is luminous automatically.Decorative frame around the panel can be decorated with the stainless steel mirror panel, and the frosting bar is the mould molding parts.Reflecting plate 4 adopts stainless steel mirror board by mould molding, and light source forms evenly soft light-emitting area through baffle reflection, reflexes on the panel literal.The side plate of doorplate and base plate can be used the engineering plastics ABS injection mo(u)lding.

Shown in Fig. 3,4: light-operated circuit is by power circuit, be serially connected with light-operated driving circuit in its output, and the output of light-operated driving circuit is connected to on-off circuit and constitutes; In the output of on-off circuit and be connected to light and show circuit and form light-operated display circuit.In addition, the output at power circuit also is parallel with online back-up source.Power supply B is by exchanging 220 volts of power supplies, power circuit mesohigh capacitor C parallel resistance R step-down current limliting, bridge rectifier through diode D1～D4 composition, output full-wave rectification electric current, provide operating voltage to light-operated circuit, showing circuit to light provides quasi-stationary current, and the online back-up source of power circuit configuration is made of rechargealle battery E and stabilivolt WC parallel connection.When civil power has a power failure suddenly, this back-up source can provide power supply about 10 hours.Power circuit is that triode BG2 shows circuit supply to light by the on-off circuit of connecting with the apparent circuit of light, and this light shows circuit and is made up of the square formation network of the mutual connection in series-parallel cluster of light emitting diode L1～L24.Light-operated driving circuit is by photoresistance RL sample circuit, and resistance R 1, RL dividing potential drop and triode BG1 amplifying circuit are formed.On-off circuit is made up of with switch triode BG2 resistance R 2.Its principle of work: ambient light illumination is sampled by photoresistance RL, resistance R 1 dividing potential drop of connecting with RL, resistance R L voltage changes with ambient light illumination, this voltage promotes triode BG1 amplifying circuit, the trapezoidal half-wave voltage signal of this amplifying circuit output change amplitude when ambient light illumination is lower than 5 luxs, is exported trapezoidal mean value minimum, when ambient light illumination during, export trapezoidal half-wave voltage signal mean value and increase greater than 30 luxs.This signal drives the on-off circuit of being made up of power switch transistor BG2, switch triode BG2 is by the trapezoidal wave amplitude control of driving circuit output, when trapezoidal half-wave drive signal mean value is increased to certain value, triode BG2 begins conducting, show circuit supply to light, when triode BG2 was saturated, light showed circuit by the electric current maximum, and light emitting diode is the brightest.When the trapezoidal half-wave voltage signal mean value of driving circuit output is little during to certain value, triode BG2 blocking-up does not show circuit supply to light, and light emitting diode is not luminous.Light show the light emitting diode L1～L24 cluster of circuit all pressure, the current-sharings of square formation network, there is fault arbitrary unit in square formation, does not influence the operate as normal of other unit.
