The utility model is characterized in that the display part of the utility model also comprises an electronic fluorescent screen, an electronic oscillating circuit which drives the luminescent screen to illuminate, a control switch and a power supply, the electronic fluorescent screen is connected with the high-voltage output end of the electronic oscillating circuit, and a control switch is connected in series between a power supply and the electronic oscillating circuit.

Description

Electronics fluorescence timer

The utility model relates to a kind of timer, refers to have the timer of lighting function especially.

General timer, as clock, table or other timers, can only use by day, in order to use timer at night, two kinds of methods of general at present employing: the one, in timer, place a miniature bulb, because bulb is a pointolite, brightness is extremely unequal, and light and shade is arranged, and brightness is also not enough, misunderstand the time easily, and power consumption is big; The 2nd, on timer, coat luminous paint or optical absorbing agent, the former has radiation pollution, the latter can only enter dark place at the light place when making with use can see that effect is all undesirable the back short time.

The purpose of this utility model is to propose a kind of timer that adopts electronics flourescent sheet illumination that can be luminous, the thickness of this electronics flourescent sheet can be accomplished 0.3mm～0.5mm, must not fill in the sheet and add inert gas, no tungsten filament, do not generate heat when luminous, have certain brightness, and whole luminous, brightness is even, and is satisfactory for result.

A kind of electronics fluorescence timer of the present utility model, it comprises the display part, direct supply has the electronics flourescent sheet of gauge tap and drives oscillatory circuit; It is characterized in that described electronics flourescent sheet place timer the display part below, two electrodes of described electronics flourescent sheet are connected on the high-voltage output end of oscillatory circuit, and the gauge tap of described flourescent sheet is series between the utmost point and oscillatory circuit of described direct supply.

Wherein, described display part can be a pointer-type, can be digital, also can adopt LCDs.

Below in conjunction with accompanying drawing and embodiment explanation.

Fig. 1 is the fluoroscopic basic structure synoptic diagram of electronics that the utility model adopts;

Fig. 2 is the discrete component electro coupled oscillator driving circuit that the utility model adopts;

Fig. 3 is the integrated circuit oscillator driving circuit that the utility model adopts.

The basic structure of electronics flourescent sheet described in the utility model as shown in Figure 1; wherein 1,2 is protective seam; 3 for containing the conductive layer of tin chloride; 4 is the luminescent layer of compounds such as Containing Sulfur zinc; 5 is one to be the metallic conduction rete of base material with aluminium; two electrodes 6 are drawn from 3 and 5 two conductive layers, add the alternating voltage of 70～220V on described two electrodes 6, and luminescent layer 4 will be at stimulated luminescence under the electric field action.This flourescent sheet energy consumption is extremely low, and whole luminous even, do not generate heat, and radiationless, the life-span is long, and shape can be made arbitrarily.

Fig. 2 is luminous electronic oscillating circuit and the wiring diagram thereof of driving flourescent sheet that the utility model adopts, and its effect is direct supply to be transformed into the pulse of 300～700HZ, and boosts to 70～220V.Fig. 3 is integrated circuit oscillator driving circuit and the wiring diagram thereof that the utility model adopts, and wherein IC adopts integrated oscillator circuit.Wherein K is a pushbutton switch, and direct supply is with button cell or general powered battery, and desk clock or large-scale clock can be used mains-supplied.Be added with gauge tap in the circuit, when needs throw light on, click switch, video screen promptly sends uniform light.This device power consumption is extremely low, electric enough one 3 square inches electronics video screen of one day consumption of 50W bulb luminous a year continuously.

One of embodiment of the present utility model, described electronics flourescent sheet are used to have clock, when table of LCDs, place display screen below, light source can replace light emitting diode as a setting, and it is more that LCDs is changed.

Two of embodiment of the present utility model, described electronics flourescent sheet are used for general clock, when table, can directly print when representing on described electronics flourescent sheet, the code name of minute, second or other times.Can be base plate also, add again in the above and put a slide, print on this slide that expression is advanced, the code name of minute, second or other express times with described electronics flourescent sheet.

The utility model has the advantages that fluorescent screen is area source, brightness is even, does not have when luminous Heat, radiationless, low energy consumption, the life-span is long, and is especially suitable as timer.
