Abstract

The utility model discloses an intelligent bed lamp, a DC bulb or an LED dot array, which is characterized in that: the DC bulb or the LED dot array is connected with a singlechip, a timer and a brightness regulating circuit are fixed in the singlechip, the push-buttons are connected with the singlechip and the power supply respectively, the singlechip is connected with an SSR solid state relay by a voltage converter, the singlechip signal is simultaneously connected with the control terminal of the SSR solid state relay, and the SSR solid state relay is connected with the power supply line. The intelligent bed lamp of the utility model can make the bulb brighten gradually after the push-button is pressed by the switch of the SSR solid state relay and the timer in the singlechip, and the lamp can make the bulb darken gradually when the push-button is repressed until the bulb is extinguished, which makes the eyes have a adaptive process, can release stimulation of the light to eyes, is convenient for people waking up at night.

Description

The intelligence bedside lamp

Technical field

The utility model relates to a kind of bedside lamp, especially relates to a kind of intelligent bedside lamp capable of automatic regulating brightness, belongs to technical field of electricity.

Background technology

We usually run into such problem in the daily life, are exactly when turning off the light evening, because unexpected the extinguishing of lamp, also do not come and go to bed or laying for goods is put in place, therefore just grope in the dark again, and are very inconvenient.Turn on the light when perhaps get up night, because lamp is by instant igniting, eyes also in time do not adapt to, and cause temporary transient dizzy of brain, and the old man is easy to so falls down.So occurred the various light fixtures that can regulate brightness on the market, as application number is the LED desk lamp that 200420022722 utility model discloses a kind of colour temperature and adjustable brightness, it includes a lamp holder that has light emitting diode, the support of lamp, the driver of lamp socket and light emitting diode and electric connector, it is characterized in that described light emitting diode comprises a power type white light light emitting diode and at least one coloured visible light emitting diode at least, described light emitting diode is fixed on the interior heat abstractor of lamp holder, the front of light emitting diode is mounted with Optical devices that are used to transform the output photo structure, and described driver includes switch, degree of lightening device and ager.This kind lamp is regulated brightness by electrical equipment, but the adjusting of brightness do not finish automatically, and can not close automatically on time.

The utility model content

Technical problem to be solved in the utility model provides a kind of capable of automatic regulating brightness and bedside lamp that can extinguish automatically at preset timed intervals.

For solving the problems of the technologies described above, the utility model provides a kind of intelligent bedside lamp, comprise direct current bulb or LED dot matrix, it is characterized in that: described direct current bulb or LED dot matrix link to each other with a single-chip microcomputer, be provided with timer and brightness regulating circuit in the described single-chip microcomputer, button links to each other with single-chip microcomputer, power supply respectively, single-chip microcomputer links to each other with the SSR solid-state relay by an electric pressure converter, the single-chip microcomputer signal connects the control end of SSR relay simultaneously, the effect of the unlatching of control power supply and shutoff general supply, described SSR solid-state relay and power line join.

Aforesaid intelligent bedside lamp is characterized in that: described SSR solid-state relay is TSZ2G48S.

The beneficial effect that the utility model reached:

Intelligent bedside lamp of the present utility model by the on-off action of SSR solid-state relay and the timer in the single-chip microcomputer, can make bulb brighten gradually after pushing button, and deepening gradually when pushing button once more, up to extinguishing.Make people's eyes that the individual procedure of adaptation be arranged, relax the stimulation of light, greatly facilitate the people who rises night, allow life become convenient eyes.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the hardware block diagram of intelligent bedside lamp of the present utility model, the intelligence bedside lamp comprises direct current bulb or LED dot matrix, described direct current bulb or LED dot matrix link to each other with a single-chip microcomputer, be provided with timer and brightness regulating circuit in the described single-chip microcomputer, button links to each other with single-chip microcomputer, power supply simultaneously, single-chip microcomputer links to each other with the SSR solid-state relay by an electric pressure converter, and described SSR solid-state relay and power line join.Wherein, SSR solid-state relay model is TSZ2G48S.Single-chip microcomputer can show current working state by a LED lamp.Button S1 is a double-point double-throw switch, promptly by next button, two switch closures are arranged, button has been pressed two circuit and has been connected, one the tunnel is that power supply is given connection, and another road is that effect is in the relay adhesive to low level signal of single-chip microcomputer, button is pressed once more and can be given the low level signal of single-chip microcomputer, and can cut off the electricity supply automatically after single-chip microcomputer is just spent a bit of time reaches the effect of turning off the light.

Regulating brightness is by single-chip microprocessor MCU output certain frequency PWM ripple, the different purpose that just can reach brightness regulation of the dutycycle of PWM ripple, and PWM is called for short pulsewidth modulation.

The course of work of the present utility model is:

When powering on, the SSR solid-state relay does not have control signal, and U2 not adhesive is in 0 power consumption state, transfers 220V voltage to 5V voltage through electric pressure converter when the S1 that pushes button (220V/3A double-point double-throw switch) time, supplies with single-chip microcomputer.Single-chip microcomputer is given SSR solid-state relay control signal immediately, and the SSR solid-state relay is the power turn-on switch also.At this time button unclamps does not influence circuit working.

After the single-chip microcomputer U1 turn-on current, the single-chip microcomputer timer is started working, and the light source that controls signal to that the output of PWM mouth increases dutycycle gradually promptly carries out the driving LED lamp by triode Q1, Q2, Q3, Q4.And increase the brightness that changes LED in time, realize turning on light gradually bright process.

If when button was pressed once more, single-chip microcomputer detected signal, PWM exports opposite signal (reducing dutycycle gradually), realizes the effect of deepening gradually.Remove when detecting PWM control relay signal AC_CTL smaller or equal to 10% time, U2 disconnects circuit.Get back to power-up state.

Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
