Abstract

A kind of clock and its method of work, have the multiple characters for showing the time including dial and pointer, on the dial, and each character only shines when being directed toward by the pointer.Due to the character luminous for only having pointer to be directed toward, and remaining character does not shine, therefore under either bright or dark state, can understand and definitely recognize the time, will not cause visual misunderstanding.

Description

Clock and its method of work

The application is Application No. 2012105508938, and the applying date is on December 18th, 2012, and invention and created name is The divisional application of the patent of " light emitting diode clock ".

Technical field

The present invention relates to a kind of clock, especially a kind of light emitting diode clock.

Background technology

Traditional clock enable character clearly using huge contrast of the character on dial and dial in color It shows to Chu, so that pointer can clearly indicate out the specific time in rotary course.But even if dial exists with character In color there is again big contrast, when clock is in dark state, still cannot clearly tell the character on dial.

The content of the invention

In view of this, it is necessary to which a kind of clock for becoming apparent from display is provided.

A kind of light emitting diode clock has to show the more of time including dial and pointer, on the dial A character, each character only shine when being directed toward by the pointer.

Due to the character luminous for only having pointer to be directed toward, and remaining character does not shine, therefore either bright or black Under dark state, it can understand and definitely recognize the time, visual misunderstanding will not be caused.

Specific embodiment

Referring to Fig. 1, the light emitting diode clock 100 of one embodiment of the invention includes pointer 10, dial 20 and outer Shell 30.There are the multiple characters 22 for showing the time on the dial 20.When the pointer 10 is directed toward a certain moment, the dial Corresponding character 22 shines on 20.In the following description, it will be directed toward with pointer 10 at 3 points and just illustrate the light emitting diode for example Clock 100.

Please refer to Fig. 2-4, the pointer 10 of the light emitting diode clock 100 includes hour hands 11 and minute hand 12.It can manage Xie Di, the pointer 10 can also include second hand.The hour hands 11 are equipped on minute hand 12 on a protecgulum 13.The pointer 10 is installed on this When on dial 20, which covers the part that is surrounded by the plurality of character 22 on the dial 20, on the dial 20 only Expose the plurality of character 22 and its neighbouring part.

There is a light guide plate 21 for being not more than the protecgulum 13 on the dial 20.The plurality of character is corresponded on the light guide plate 21 22 radially offer multiple guide-lighting slots 23.Each leaded light slot 23 corresponds to a character 22.20 center position of dial It is provided with a shaft 26.The pointer 10 is rotated around the shaft 26.The dial 20 is provided with multiple corresponding to each guide-lighting slot 23 Light emitting diode 24.The plurality of leaded light slot 23 is corresponded with the plurality of light emitting diode 24.It is to be appreciated that the plurality of shine Diode 24 is side direction LED 24.The light-emitting surface of each light emitting diode 24 is towards corresponding guide-lighting slot 23.The leaded light A fluting 25 is opened up among plate 21.The shaft 26 and the plurality of light emitting diode 24 are exposed from the fluting 25.The fluting 25 Connect the plurality of guide-lighting slot 23.Preferably, each guide-lighting slot 23 is through the outer boundary of the fluting 25 and the light guide plate 21.The scale Disk 20 is installed in shell 30, preferably to be supported.

In the present embodiment, on the dial 20 there is 1~12 totally 12 characters 22, accordingly opened up on the light guide plate 21 There are 12 guide-lighting slots 23.Correspondingly, which is provided with 12 light emitting diodes 24.The dial 20 is rounded, this is more A character 22 is evenly arranged in the closing at the position of its excircle of the dial 20.The protecgulum 13 is with the light guide plate 21 in half Footpath is less than the circle of the dial 20.The fluting 25 is rounded, the equal length of each guide-lighting slot 23.It it is to be appreciated that should Dial 20 is not limited to circle, and the plurality of character 22 is also not necessarily limited to be uniformly distributed on the dial 20.With the plurality of character 22 different distributions, the distribution of the plurality of leaded light slot 23 and length also change immediately.

The plurality of character 22 is made of reflectorized material, and the plurality of character 22 and the color of the dial 20 approach.When When character 22 is not by illumination, which does not shine, and color is almost identical with the dial 20.In the present embodiment, the quarter It is in black when scale 20 is not illuminated with the character 22.Observer cannot distinguish one from the other each character 22 with carving when not examining Scale 20.When pointer 10 goes to some integral point moment, the light emitting diode 24 of corresponding position is lighted.Light by leading accordingly Light slot 23 is irradiated on corresponding character 22.Such as in this implementation, pointer 10 is directed toward 3 timings, and " 3 " on dial 20 are right The light emitting diode 24 answered is illuminated.Light is irradiated on " 3 " by light by corresponding guide-lighting slot 24, and " 3 " are sent out by reflecting Light.At this point, due to only having " 3 " to shine, and other characters 22 are in dark state, therefore no matter observer is bright or black In dark environment, it can see the time for 3 points just exactly.When pointer 10 is not directed on schedule, such as it was directed toward for three thirty When, " 3 " still shine.Preferably, the minute hand 12 and hour hands 11 can be made of luminescent material or fluorescent material, thus hour hands 11 and minute hand 12 can receive the light of light emitting diode 24 always and be maintained at luminance so that light emitting diode clock 100 can still show the specific time in dark surrounds.It is to be appreciated that the light emitting diode clock 100 further includes control Module and driving module.The light emitting diode 24 that the control module is used to that the pointer 10 to be controlled to be directed toward is opened.The driving module For lighting the light emitting diode 24 being directed toward by pointer 10.

Since the plurality of character 22 is to be shone by reflecting rather than shone in itself, save due to the use of luminescent material Make the high cost of character 22.Again since the character 22 for only having pointer 10 to be directed toward shines, and remaining character 22 is in and scale In the state of 20 almost identical color of disk, therefore under either bright or dark state, when can understand and definitely recognize Between, visual misunderstanding will not be caused.Meanwhile except when outside preceding time, all no light emitting diode 24 of other times illuminates, Therefore people can be allowed to feel the disappearance of time, so as to make one more to treasure life.In addition, the light emitting diode clock of this case 100 also great individual characteies and rich in artistic feeling, are different from other ordinary clock.
