Description

A kind of Luminous wrist watch

Technical field

The utility model relates to wrist-watch, relate in particular to a kind of can be under dark surrounds self luminous wrist-watch.

Background technology

Wrist-watch is a kind of timing tool that can carry, can let the user understand the time whenever and wherever possible, and work and life are had very great help.When using wrist-watch night, need auxiliary illumination to see clearly the time, in some wrist-watch light structures is installed at present; So that auxiliary light to be provided; For example light emitting diode is set around the dial plate, and is the battery of led powered in the wrist-watch set inside, above-mentioned light structures is complicated; And light structures is installed is made the volume of wrist-watch increase, be unfavorable for the attractive in appearance of wrist-watch.

The utility model content

The purpose of the utility model provides a kind of Luminous wrist watch, and complicated light structures need be installed, can autoluminescence, and make things convenient for the user under dark surrounds, to see the time clearly.

To achieve these goals, the utility model embodiment provides a kind of Luminous wrist watch, comprising:

Watchcase;

Dial plate is arranged in the said watchcase, and said dial plate is provided with scale marker;

Indicator is arranged at the center of said dial plate through an indicator axle;

By first luminescent layer that phosphor material forms, covering is arranged on the said indicator.

Wherein, said indicator comprises hour hands and minute hand.

Wherein, said Luminous wrist watch also comprises:

Second luminescent layer that is formed by phosphor material covers and is arranged at least on the said scale marker of part.

The Luminous wrist watch of the utility model has following beneficial effect:

When 1, this wrist-watch perhaps has light-illuminating by day; The luminescent layer that is coated with on the indicator can absorb energy, and changes the energy that absorbs into visible light, when do not have sunshine or light-illuminating night; It still can continue luminous, under dark surrounds, sees the time to make things convenient for the user clearly.

2, the luminescent layer that on the scale marker of dial plate, is coated with is luminous at night, makes the user can conveniently understand the time apace.

3, because the initial briliancy of luminescent layer is every square metre of 7400cd; Visual after time is more than 80 hours; Therefore can guarantee that wrist-watch all is in luminous state at any time; It does not realize illumination according to other light structures, and is simple in structure, and can not occur causing the defective that can't throw light on because light structures breaks down yet.

Description of drawings

Fig. 1 is the structural representation of the Luminous wrist watch of the utility model.

Embodiment

The Luminous wrist watch of the utility model embodiment; On the indicator on the Luminous wrist watch, be coated with the luminescent layer that one deck is formed by phosphor material; When receiving light source irradiation, this luminescent layer absorbs energy; And change the energy that absorbs into visible light, and can continue after stopping luminously exciting, therefore can make things convenient for the user under dark surrounds, to see the time clearly.

Be illustrated in figure 1 as the structural representation of the Luminous wrist watch of the utility model, this Luminous wrist watch comprises:

Watchcase 101;

Dial plate 102 is arranged in the said watchcase 101, and said dial plate 102 is provided with scale marker 103; This scale marker 103 can be the random time point symbol in " 1-12 ", also can be the scale mark that is used for express time point.

Indicator 104 is arranged at the center of said dial plate through an indicator axle;

By first luminescent layer (scheming not shown) that phosphor material forms, covering is arranged on the said indicator 104.

Said indicator 104 comprises hour hands and minute hand, and is current, also can comprise second hand.

Certainly, the Luminous wrist watch of the utility model can also comprise:

One second luminescent layer (scheming not shown) that formed by phosphor material covers and is arranged at least on the said scale marker 103 of part.

Like this, not only luminosity, luminous volume all can increase, and make the user can conveniently understand the time apace.

In the specific embodiment of the utility model; In order to guarantee that Luminous wrist watch can both emit beam at any time; Phosphor material can adopt the long Persistence and high brightness fluorescent materials of synthetic to process; This long Persistence and high brightness fluorescent materials is a matrix with the alkali earth metal aluminate of boracic, and more than one RE element is an activator, and its chemical molecular formula is: MO _n[(Al _1-aB _a) _2-b/3O _3-b(OH) _b]: cRE, wherein:

M representes to be selected from least a earth alkali metal in magnesium, calcium, strontium or the barium;

RE representes to be selected from lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, at least a REE in the lutetium;

N is smaller or equal to 10, more than or equal to 0.5;

A is smaller or equal to 0.5, more than or equal to 0.0001;

B is smaller or equal to 2, more than or equal to 0.0001;

C is smaller or equal to 0.6, more than or equal to 0.0001;

Part is by OH displacement at least for oxygen atom in the crystal structure that burns till body that above chemical molecular formula is represented, and it is to carry out wet grinding through the material solution with one or more, makes each composition in the raw material be ground to particle diameter and prepares for the 50-10000 nanometer.

And the long Persistence and high brightness fluorescent materials of above-mentioned synthetic can prepare through following method:

At first, take by weighing raw material, and it is ground to particle diameter is the 50-10000 nanometer by proportioning;

Secondly, the raw material after grinding is inserted crucible, and this crucible is put into the pressure electric furnace, under reducing atmosphere, calcining is 2-5 hour under the 600-1200 degree celsius temperature;

Once more, will burn till body and from electric furnace, take out cool to room temperature;

At last, the cooled body that burns till is ground to form powder.

The initial briliancy of the luminescent powder of preparation is every square metre of 7400cd as stated above, and visual after time is more than 80 hours.

Certainly; Should be understood that above-mentioned phosphor material also can other phosphor material, like disclosed phosphor material in No. 95109878.0 patents; And for example disclosed phosphor material etc. in 97100694.6,99100285.7, No. 98123460.7 patents is not described at this one by one.

The Luminous wrist watch of the utility model has following beneficial effect:

When 1, this wrist-watch perhaps has light-illuminating by day; The luminescent layer that is coated with on the indicator can absorb energy, and changes the energy that absorbs into visible light, when do not have sunshine or light-illuminating night; It still can continue luminous, under dark surrounds, sees the time to make things convenient for the user clearly.

2, the luminescent layer that on the scale marker of dial plate, is coated with is luminous at night, makes the user can conveniently understand the time apace.

3, because the initial briliancy of luminescent layer is every square metre of 7400cd; Visual after time is more than 80 hours; Therefore can guarantee that wrist-watch all is in luminous state at any time; It does not realize illumination according to other light structures, and is simple in structure, and can not occur causing the defective that can't throw light on because light structures breaks down yet.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
