Abstract

The utility model belongs to the clock technical field, which relates to the combination and the installation of the clock structure and the electron luminous component. Due to the fact that optical controlling circuit controlling luminous component is adopted, when the environmental luminous ray becomes dark, a clock lighting lamp can be automatically lighted to light, which makes the people can clearly see the indicating time of the clock at night, moreover, the soft luminous ray can be doubled as the sleeping lamp, which facilitates the night sitting. The optical controlling luminous clock has simple process, low power consumption, long service life; the lighting lamp does not need to be changed.

Description

Optocal controlling luminous clock

The utility model belongs to the clock and watch technical field, relates to the clock and watch structure, the combination of electron device and installation.

Existing clock and watch generally can only use by day or under the bright light environments, do not light the time that illuminating lamp does not just see indication at night.

Existing clock and watch lean against on the dial plate He on the indicator and coat radioactive luminescent material, so that the time indication at night to be provided.But its brightness is very low, and distance slightly far just is difficult to see clearly.And As time goes on, its brightness is also more and more lower.Other has some night illumination clock and watch also to exist some deficiency, looks into application number 89202286.8, lacks the automatic control of photosensitive device, after energized, light emitting diode is kept burning day and night round the clock, this has come loss a lot of unnecessary electric energy, and two influence the serviceable life of element.Look into application number 88216569.0, for the time of seeing must go out the sound, so both influenced other people and had a rest when wake up night, not too convenient again.

The purpose of this utility model provides a kind of light-operated luminous clock, by the variation of light round the clock of natural light, realizes opening bright automatically and extinguishing the clock and watch illuminating lamp, and the lamp but the while double as is slept carries out daily life illumination at night.

The utility model is on existing clock and watch, controls light emitting diode with photoresistance, and timepiece dial is thrown light on.

1. 2. light emitting diode of photoresistance

Structure of the present utility model as shown in Figure 1, it by clock and watch and the illumination two parts form.Light emitting diode (6) is installed in the front or the back of dial plate (7), photoresistance (3) is installed on the watchcase (5), circuit board (2) is fixed on the inside of watchcase (5), and power lead (1) is connected on the power supply (14), and reflective lining ring (13) is installed in the front of dial plate (7).

Circuit theory of the present utility model as shown in Figure 3.Connect on the 220V power supply, by transformation, rectification, dividing potential drop.Photoresistance is the power of induced environment light 1., control triode (BG) conducting or disconnection, thus the control light emitting diode is 2. luminous.

When light emitting diode among Fig. 1 (6) is lighted, reflective lining ring (13) can reflection ray, thereby increased the brightness that projects the light on the dial plate, because power supply (14) is in the outside of clock and watch, thereby can not produce influence of magnetic field to the travel time system of mechanical clock, can not influence the timekeeping performance of clock and watch.

The utility model is on existing clock and watch the light-controlled electronic circuit to be installed, dial plate is thrown light on, except that having the original characteristic of clock and watch, increased night or do not have and also can see the clock and watch function of instruction time under the illumination condition clearly, but and the double as lamp of sleeping, make things convenient for daily life activity at night.Because it is rational in infrastructure, clock and watch there is not the magnetization influence, technology is simple, and power consumption is less than 0.9 watt, and cost is low, long service life, thereby be suitable for being installed on the various clock and watch such as machinery, quartz, electronics, widely applicable, be convenient to popularize, be beneficial to large-scale production.

Claims
