Abstract

The utility model discloses a clock controlled desk lamp, which belongs to the field of illumination tools. The apparatus comprises a desk lamp, a time clock IC circuit, switches K2 and K3, an amplifying transistor T, and a magnet D. The output end of the time clock IC circuit is connected with the amplifying transistor T, the output end of the amplifying transistor T is connected with one end of the magnet D, the other end of the magnet D is connected with one end of the connection switch K3, the switch K3 is connected with the other output end of the time clock IC circuit, the switch K2 in connected in parallel with the switch K1 of the original desk lamp, and the switch K2 is close to the upper end of the magnet D. The utility model has advantage that the clock alarms and the lamp is lightened at the time predetermined by user, living and working is thus facilitated, and the desk lamp has simple structure and low price.

Description

Clock control desk lamp

Technical field

The utility model relates to the illuminations aspect, specifically is a kind of Clock control desk lamp, is suitable for family, hotel and the place of the office that is used to throw light on, and needing at night to be particularly suitable for the people in control time.

Background technology

For the people who gets up night or getting up early is gone to work, regularly be absolutely necessary with alarm clock.It is as dark as a stack of black cats that but quarter-bell rings in the backhouse, and this environment is unfavorable for people timely, and people are when ringing quarter-bell surely for this reason, always more as early as possible, so that have time enough to go to regain consciousness, and this fashion is in the people of twilight state, it is very inconvenient going in the dark to turn on light.Desk lamp miscellaneous is arranged in the market, and people have designed soft-touch control desk lamp, lamp dimmer and energy-saving multiple lighting in recent years, but they all just have the function of single illumination.Some are also arranged about desk lamp regularly, but structure is complicated.

Summary of the invention

At the deficiencies in the prior art, the utility model provides a kind of Clock control desk lamp, can finish automatically according to people's preset time to give the correct time and the bright dual-use function of lamp.

The utility model is realized with following technical scheme, and a kind of Clock control desk lamp comprises desk lamp and clock IC circuit, also comprises K switch 2, K3, amplifying triode T and electromagnet D; Described clock IC circuit and electromagnet D form a closed-loop path, are in series with amplifying triode T and K switch 3 between clock IC circuit and electromagnet D; Described K switch 2 is connected in parallel on the two ends of former desk lamp switch K1, and K switch 2 is near the upper end of electromagnet D.

Operation principle is: Closing Switch K3 configures the time that alarm clock rings, when arriving the time of setting, drive current after the audio signal of clock IC circuit output is amplified by amplifying triode T is at 3～6mA, and logical the powering on of electromagnet D this moment is K switch 2 adhesives, at this moment the desk lamp circuit is connected, and desk lamp is bright.

The beneficial effects of the utility model are: it is bright to ring the while lamp at the pre-set time clock of people, the live and work that is convenient for people to, and it is simple in structure, cheap simultaneously.

Description of drawings

Accompanying drawing is the utility model circuit theory diagrams.

The specific embodiment

As shown in drawings, a kind of Clock control desk lamp, comprise desk lamp, clock IC circuit, K switch 2, K3, amplifying triode T and electromagnet D, the output of described clock IC circuit connects amplifying triode T, the output of amplifying triode T connects the end of electromagnet D, the other end of electromagnet D connects an end of K switch 3, and K switch 3 is connected to another output of clock IC circuit; Described K switch 2 is connected in parallel on the two ends of former desk lamp switch K1, and K switch 2 is near the upper end of electromagnet D.Described K switch 2 is magnet control spring contacts, and amplifying triode is a NPN type triode.

Closing Switch K3, when arriving predefined time, the drive current after the audio signal of clock IC circuit output is amplified by amplifying triode T is at 3～6mA, logical the powering on of electromagnet D this moment, K switch 2 adhesives, at this moment the desk lamp circuit is connected, and desk lamp is bright.Do not allow desk lamp bright if only want to allow alarm clock ring, as long as cut-off switch K2 is just passable.

Claims

1. a Clock control desk lamp comprises desk lamp and clock IC circuit, it is characterized in that: also comprise K switch 2, K3, amplifying triode T and electromagnet D; Described clock IC circuit and electromagnet D form a closed-loop path, are in series with amplifying triode T and K switch 3 between clock IC circuit and electromagnet D, and described K switch 2 is connected in parallel on the two ends of former desk lamp switch K1, and K switch 2 is near the upper end of electromagnet D.

2. Clock control desk lamp according to claim 1 is characterized in that: described amplifying triode T is a NPN type triode; Described K switch 2 is magnet control spring contacts.
