Abstract

The utility model discloses a night visual clock, which comprises a transparent cover cap, a dial plate equipped with pointers, a shell, and a semiconductor solid-state lighting device consisting mainly of an electrical source and an illuminant. The electrical source is arranged in the shell, and the illuminant is arranged on a side wall between the transparent clock cover and the dial plate. The panel of the shell is provided with a night vision switch which is connected to a loop through which the electrical source supplies electricity to a light-emitting diode. The utility model has the advantages of simple structure and strong practicability. Moreover, the utility model can provide lighting for dial-plate in darkness to see the time clearly, and does not disturb other sleeping roommates when in use.

Description

Night visual clock

Technical field

The utility model relates to the clock and watch technical field, particularly has lighting function, makes things convenient for the clock of seeing clock night to make the field.

Background technology

The clock that generally uses in the bedroom comprises mechanical activation clock or electronic type clock, and the two must be under the illumination of visible light, and people just can find out " time " that pointer is indicated.

Not having at night when especially midnight, people woke up, usually needs the understanding time under the dark surrounds of illumination.If the time also early all can wish to continue sleep.But the time of seeing clearly need turn on the light.Other people can be had influence on like this, and own further sleep can be influenced.

The utility model content

The purpose of this utility model provides a kind of visual clock at night that dial plate illumination can be provided in the dark, see the time clearly.

This novel purpose is achieved in that visual clock at a kind of night, comprise transparent cover, dial plate, the casing of pointer are housed, also has the semiconductor solid lighting device of mainly forming by power supply and luminophor, power supply is arranged in the casing, luminophor is arranged on the sidewall between transparent cover and the dial plate, machine shell panel is provided with the night vision switch, and the night vision switch is connected in the loop of power supply to the light emitting diode power supply.

The luminophor of above-mentioned semiconductor solid lighting device is a light emitting diode.

The technical program is that the semiconductor solid lighting technology is applied on the existing clock, solves the lighting problem of recognize time in the dark.The semiconductor solid lighting technology is very ripe, and light emitting semiconductor device wherein is also a lot.As the LED light emitting diode promptly is cheap, widely used emitting components.

Adopt this programme, people wake up midnight, only need press the night vision switch on the casing, the power supply power supply, and light emitting diode is lighted, and with dial illuminance, even under the drowsy situation, also can see the sensing of pointer on dial scale, thereby find out the definite time.

The beneficial effect of this programme is:

1, makes things convenient for and see clock night

People can only need closed night vision switch under not turning on light situation night, dial plate can obtain illumination, thereby finds out the concrete time;

2, do not influence sleep with the chamber people

Turn on light and see that clock can influence the sleep with the chamber people, and the illumination of the light emitting diode of this programme only guarantees the illumination of dial plate is got final product, thereby the luminous illumination of institute is minimum, can not form substantially interference and influence with the chamber people;

3, low cost of manufacture is easy to promote the use of

4, energy consumption is minimum

The night vision switch is the normal off open type, and is general only closed in use.In obsolete most times, there is not power consumption.

Description of drawings

Fig. 1 is this novel stereographic map;

Fig. 2 is the assembling synoptic diagram of shown in Figure 1 novel casing, transparent cover, decoration trim ring.

Embodiment

Fig. 1 Fig. 2 illustrates, and is provided with core section in the casing 1 of clock, or the mechanical type movement, or the electronic type movement, on the dial plate of clock pointer is housed, as, hour hands and minute hand (second hand can also be arranged).Normally, transparent cover 2 also is provided with decoration trim ring 3 with the junction of casing.Semiconductor solid lighting device (electron emitting structure of also can saying so) is made up of power supply and luminophor.Power supply is provided with in the idle space of casing, and luminophor generally adopts the LED light emitting diode.Light emitting diode 4 is arranged on the sidewall between transparent cover and the dial plate.Usually, also be provided with (as gluing) decoration trim ring 3 (Fig. 2) on the transparent cover 2 of casing.

Night vision switch 5 is connected in the loop of power supply to light emitting diode power supply, and the night vision switch is arranged on the bottom of machine shell panel, with handled easily.Light emitting diode is generally 2-4, selects for use according to the dial plate size.As shown in Figure 2, its 4 of light emitting diodes, equally spaced being distributed on the sidewall.A plurality of light emitting diodes can in parallelly use, and the night vision switch then is located in the total loop of power supply.

By day or when not needing to add illumination night and showing the time, generally put the night vision switch in off-state, only when night, can press this switch, light-emitting diodes is in control power supply, sends small light, illuminate dial plate, the end user then can see the position of pointer clearly, thus the time of determining.One, can saves energy, prolong clock serviceable life; Two, can get rid of turns on light sees that clock disturbs the drawback with chamber people sleep.

This night, visual clock was if provide 220 volts of voltage supports, then can add radio function again.Can conveniently utilize the standard time of radio station broadcast to calibrate clock like this, and can the radio station broadcast be set to alarm clock.

The utility model is simple in structure, but practicality is very strong, after wakeing up night, can easily, not check the time with influencing other people, and is very energy-conservation during use, thereby, can finely satisfy people's needs, have the bigger market demand.
