Abstract

The utility model relates to a lighting decoration device for clock and watch, which relates to the technical field of the electro-optical lighting technology. The lighting decoration device for clock and watch utilizes the circuits (such as limit current circuit, light modulation circuit, light control circuit and direct current transformation circuit, etc.) or part of which to light up the colored electric light source or the white electric light source; then the light source is put on the back surface or the lateral surface of a semitransparent watch dial to light up the watch dial, then the watch dial can dispatch the beautiful and soft light; the lighting decoration device for clock and watch can be used for the time lighting at night, and can be doubled as the sleeping light. If the watch dial is made into the chromatic watch dial or is perforated or is inserted with the colored glass beads, the plastic diamonds and the light-emitting diode, etc., which can cause the clock face to illuminate to be more beautiful. The lighting decoration device for clock and watch can be doubled as the decorative lamp, and acts the function that one thing is provided with multiple functions.

Description

Light decoration device for clocks and watches

The utility model is a kind of clock and watch illumination and decoration device, relates to the electric light lighting technical field.Conventional clock and watch do not have lighting device, just can't give the correct time by reading when dark, and the illumination and decoration that also is far from being more can not be done long-term illumination in night with two joint dry cell power supplies and give the correct time.The present invention's purpose just is to address these problems, and will give the correct time, throws light on, decorate and be melted into a whole, and makes it one-object-many-purposes.The enforcement of the utility model is to utilize circuit such as current limliting, light adjusting circuit are light-operated, DC converting or wherein a part of circuit to light colour or white light source, dial plate is illuminated in the back side or the side that light source are placed on translucent dial plate again, so dial plate just can send beautiful soft light; The lamp but the illumination double as that gives the correct time when can be used as dark is slept, if dial plate is made colour or stamped the hole in the above, samlto pearl, plastics diamond, light emitting diode etc. just can make clock face glittering, and be beautiful more, has the function of interior decoration illumination concurrently.The utility model also can utilize dry cell, by current-limiting circuit, lights 14 light emitting diodes of different colours, and its electric current is limited between the 0.2-5mA (can regulates electric current according to user's needs, can certainly transfer more greater or lesserly).Therefore just can day and night lighting clock and watch some months with two joint dry cells, be assemblied on the crystal clock of conventional use dry cell and just can make it more practical and attractive.The utility model can be used direct current work, and also available alternating current work, but also AC/DC have and gives the correct time, throws light on, decorates three kinds of effects, also has power saving, cost is low, making is simple, small investment, advantage such as applied widely.

Description of drawings:

Fig. 1 is a clock and watch back lighting decoration device structural map.

1, dial plate 2, colourful transparent plastics diamond or light emitting diode 3, double-colored five or seven lamps (a kind of fluorescent lamp that does not need ballast resistor) 4, light adjusting circuit 5, the light-operated circuit of helping secretly.

Fig. 2 is the clock and watch illumination and decoration device R that 14 light emitting diodes are formed ₁, R ₂, R ₃, R ₄Current-limiting resistance; E is a dry cell.

Embodiment 1, as shown in Figure 1, put two double-colored five or seven lamps 3 behind at clock and watch plastic front board 1, the first half of lamp is red, Lower Half is green, light sees through dial plate takes on a red color dial plate top, it is green that the bottom is, pointer and numeral are because the light tight black that is, again owing to only penetrate to come and transmit dial plate from the translucent dial plate back side, so the color of light is very soft quiet and tastefully laid out, if 12 at dial plate get the plastics diamond of inlaying green and redness on the position respectively ready or load onto light emitting diode 2 again, then light see through diamond glitter beautiful more, but since lamp have certain brightness so double as is slept lamp, can install light adjusting circuit 4 additional if dislike too bright, to adjust light intensity, for further economize on electricity can add light-controlled switching circuit 5 again, it is thrown light on when dark, also can install DC transfer circuit additional and use dry cell, accumulator or solar cell work, certainly for the decorative lighting function is all arranged round the clock, or state circuit, five or seven lamps directly are connected on the civil power in order to reduce cost also can not load onto.

Embodiment 2, as shown in Figure 2,14 light emitting diodes are divided into three groups, form by three kinds of colors, for example be contained on the long and short hands of clock with two small size yellow light-emitting diodes, be placed on an orange luminescence diode on positive 12 positions of clock, remaining 11 red light emitting diodes is placed on 1 o'clock to 11 o'clock the timing position, and three groups of light emitting diodes are separately after the parallel connection, by three current-limiting resistance R that resistance is different ₁, R ₂, R ₃Receive on the positive pole of power supply, the negative pole of power supply is by variable resistor R ₄Be connected with the negative pole of 14 light emitting diodes, adjust R ₁, R ₂, R ₃Value can adjust three groups of relative brightnesses between the light emitting diode, regulate R ₄Can adjust total current and total light intensity, general total current can be adjusted between the 0.2-5mA, also can regulate according to customer requirements, and therefore battery of two joints just can be put first-class some months, cooperates conventional batteries formula crystal clock to use very convenient.
