Abstract
The utility model provides a time display device of a low illumination which is characterized in that: the device consists of light emitting diodes which are arranged at pointers of a clock or a hanging clock; and an electronic control device which controls the operations of the light emitting diodes. Because the utility model makes use of the semiconductor light emitting diodes with a high luminous efficiency and a long service life as the light resource, arranges the diodes at the pointers and the numbers or characters on a clock panel and uses the electronic controller to light the light emitting diodes, the time can also be displayed normally in the low illumination and the utility model has not only the strong practicality, but also a certain enjoyment. Therefore, the utility model is a time display device of a low illumination with the controllable luminescence time, the high brightness, the long service life, which does not produce any pollution.
Description
The utility model relates to a kind of display device, especially a kind of device that is used in the time that still can demonstrate on desk clock or the wall clock when low-light (level).
Pointer wall clock or the desk clock of selling on the market comprises crystal clock and mechanical clock at present, can only just can find out the time indication in the high occasion of illuminance, then can't indicate in the occasion that illuminance is low.For solving the time showing problem of low-light (level), prior art is to be coated with fluorescent powder on the hand of a clock or on the character of clock face, or is coated with the fluorescent powder that has participated in radioelement.Not only fluorescent lifetime was short after single fluorescent powder was stimulated, and brightness is low; Overcome above-mentioned deficiency though participated in the fluorescent powder of radioelement, brought environmental pollution and human body is caused murder by poisoning.Therefore, be necessary prior art is improved.
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of fluorescent lifetime controlled, and the brightness height does not produce the low-light (level) time display apparatus of any pollution.
The technical solution of the utility model is: a kind of low-light (level) time display apparatus is characterized in that it is made of the electric controller of being located at the light emitting diode on the pointer and controlling this diode operation.Light emitting diode on the described pointer is located on one or more points of pointer, perhaps is located on the line of pointer, perhaps is located on the face of pointer, so that when low-light (level), knows the time that demonstrates by the luminous second tube sheet on the pointer.Light emitting diode on the described pointer is located on hour hands and the minute hand, is used for accurately showing a certain concrete time.Described light emitting diode also comprises is located at the numercal light emitting diode of clock panel, so that demonstrate different time locations intuitively.Described electric controller is made of armature circuit and electronic control circuit.Described armature circuit is made of the brush and the collector ring that are installed between pointer, so that light light emitting diode on the pointer by electronic control circuit, reaches the purpose of demonstration time.Described electronic control circuit comprise the illumination switch formed by photoresistance and triode and by integrated circuit and triode form between cease oscillator.
The utility model compared with prior art has following advantage and effect: because this device utilizes the semiconductor light-emitting-diode of luminescence efficiency height, long service life to make light source, and be installed in it on pointer and the numeral or character of clock panel on, by electronic controller light emitting diode is lighted, thereby under low-light (level), also can normally show the time, not only has stronger practicality, but also has certain sight, therefore, be that a kind of fluorescent lifetime is controlled, the brightness height, long service life does not produce the low-light (level) time display apparatus of any pollution.
