Abstract

The utility model belongs to the clock technical field, which relates to the designing, the manufacturing and the installing of the clock structure and the luminescent device. Due to the fact that an electroluminescent screen clock dial is adopted, the electroluminescent clock not only can be used at day or in bright environment, but also can be used at night or in the dark environment. Moreover, the electroluminescent clock can be doubled as the sleeping lamp, and has the function of beautifying and decorating the indoor environment. The luminescent screen used by the electroluminescent clock has little power consumption and long lifetime, and can be changed from time to time.

Description

Electroluminescence clock

The utility model belongs to luminous clock and watch technical field, relates to manufacturing and designing and clock and watch structural design and field engineering of electroluminescent device.

The clock and watch that use generally can only by day or be seen clearly under the bright light environments time that indicator is indicated now, because of its no display device brings very big inconvenience.In daily life and work, people need the night observation time, and this must open room lighting equipment, has so both wasted electric energy, influences other people again.Particularly in the open air, both not illumination was again under the situation at pitch-dark night, can't determine correct time especially.

Someone once was coated with the permanent light material on wrist-watch or miniature clock and watch, so that see the time of indicator indication under night or the dark surrounds clearly.Yet for large-scale clock and watch, adopt the permanent light material to show and be difficult to realize as clock and watch, and since the radioactivity of permanent light material be out of use gradually aspect the clock and watch demonstration.

The purpose of this utility model has provided a kind of electroluminescence clock, not only uses by day or under the bright light environments, but also can be under night or dark surrounds, clearly without other light fixture demonstrates the time.The lamp of simultaneously can double as sleeping, the effect with beautifying and decorating indoor environment.

The utility model is on existing clock, makes a luminous plaque with electroluminescent device, shows character or pattern on the dial, the position of indicator.With a switch, photosensitive device control electroluminescent panel.

Fig. 1 is a structural drawing of the present utility model.Form by clock part and display part.1 is shell among the figure, and 2 is bell jar, 3 luminous plaques, and 4 dial plates, 5, minute hand, 6 second hands, 7 hour hands, 8 movements, 9 optical receivers, 10 cover plates, 11 power control switch, 21 is battery case.Its optical receiver 9 is a photosensitive device.Wherein 4,5,6,7,8,12 is the clock part, and 3,4,9,11 is the display part.

Fig. 2, Fig. 3 are front view (FV) of the present utility model.

Fig. 4 is an electroluminescence screen structural drawing on the luminous plaque.12 organic or inorganic transparent substrates among the figure, 13 transparency conducting layers, 14 luminescent layers, 15 reflection horizon, 16 metal electrode layers, 17 organic or inorganic sealants, 18 is second contact conductor, and 19 is first contact conductor, and 20 is light-emitting area.

Fig. 1 has provided structural drawing of the present utility model.Electroluminescent panel 3 is positioned on the rear portion of dial plate 4 by shell, and the middle part is connected with movement 8.Optical receiver 9 is positioned on the appropriate location of dial plate 4, is attempted by in the power control switch 11.Power control switch 11 is fixed on the shell 1, and two lead-in wire is directly introduced civil power or come out from solar cell, through the electric current of direct current exchange conversion.Under bright light environments, because the effect of optical receiver 9 makes power control switch 11 Control current can not enter in the luminous plaque 3, but under the ambient black situation, optical receiver 9 makes power control switch 11 introduce luminous plaque 3 to electric current.Luminous plaque 3 begin luminously after having electric current to feed, at this moment can clearly see clearly on the clock face, and numeral on the dial plate 4 or character, therefore the position of indicator makes people can know definite time.Optical receiver 9 is a photoelectric cell, or photoresistance or photodiode.

Power control switch 11 is a contact relay, or the oncontacting electrical relay.Fig. 6 has provided control chart.Optical receiver 9 receives light source, and the electric current that makes power control switch 11 introduce disconnects, and luminous plaque 3 no currents therefore can not be luminous.Yet make the reception light time at optical receiver, power control switch 11 makes luminous plaque 3 have electric current to flow into, and luminous plaque 3 is luminous.

Fig. 5 is the block scheme that utilizes sun power.Solar cell becomes electric energy with transform light energy, is stored in the accumulator.Night, light-operated circuit was connected accumulator and direct-current-alternating-current converter, and voltage of intermediate frequency makes it luminous in addition on the electroluminescent panel 3 on the clock.

On one flat plate, make luminous plaque 3, as the light-emitting display device of clock with electroluminescence screen.Luminous plaque 3 is installed in the rear portion of the dial plate 4 of clock.Owing to the existence of luminous plaque 3, people can see character or pattern on the dial plate 4 clearly under dark surrounds like this, and the position of indicator, thereby determine the indicated time of clock.Character on the dial plate 4 or pattern have several ways, are transparent as character, pattern, and other parts are opaque; Perhaps character, pattern are opaque, and other parts are transparent.Luminescent screen has different colours, and as blue, yellow, green, red etc., so the character on the dial plate 4 or pattern displaying go out different colours.Minute lattice point also can be done as character, pattern, can be transparent, also can be opaque.

Luminescent screen thickness is 0.5mm-4mm, and luminosity is the 3-15 nit.The substrate of luminescent screen and sealant for organically both fluoroplastic or inorganic be sheet glass.Transparency conducting layer is the SnO that special warfare is made ₂Or In ₂O ₃Thin layer.Luminescent layer is the mixolimnion of organic bond and luminescent powder.The reflection horizon is organic binder bond and titanium dioxide mixolimnion.Metal electrode layer is materials such as vacuum coating Cu, Ag, Al.

The power supply of luminescent screen can be a civil power, also can use solar cell.Fig. 5 makes the synoptic diagram of power supply for solar cell.Photoelectric cell is adopted in the control of luminescent screen, photoresistance, and phototriodes etc., switch are contact relay or contactless relay.Fig. 6 is the control section synoptic diagram.

The utility model is electroluminescence screen of peace on existing clock, can not have the time of seeing the clock indication under illumination or the dark situations clearly at night.Electroluminescence screen has the little characteristics of power consumption, every square centimeter of consumption of having only tens microamperes.If show and the pointer illumination that as the character on the general quartzy clock face its power consumption has only 3mA-5mA, 0.05 yuan-0.10 yuan of month electricity charge.When under civilian electricity, using, reach 5 years serviceable life continuously.If utilize light-operated or other opertaing device, the life-span can reach 10 years, also luminous plaque can change at any time, therefore satisfy the requirement in serviceable life of clock fully.

Fig. 2, Fig. 3 are the synoptic diagram of two kinds of clocks.Roman number among Fig. 2 on the dial plate, plum blossom are lighttight, and other parts are printing opacities.Arabic numeral among Fig. 3 on the dial plate, pentagram are printing opacities, and remainder is lighttight.The arabic numeral of luminous plaque correspondence or the luminescent screen of Roman number size are 30mm*30mm*4mm, totally ten two, and the luminescent screen size 100mm*100mm*4mm of corresponding pointer part, one.Luminescent screen is green.
