Abstract

The utility model discloses a control circuit of clock-controlled energy saving road lamp, which comprises an output module connected with a road lamp, wherein the output module is respectively connected with a control circuit, a timing device and a comparator, the comparator is further respectively connected with a control circuit and the timing device, and the output module further comprises a night output module and a working time output module which are connected with the output module. Since the timing device and the comparator are arranged in the control circuit of the road lamp, the road lamp can be automatically opened and closed according to the set different time, thereby realizing the aim of saving energy, and the road lamp gradually becomes bright or gradually extinguishes along with the light beam, which is more humane.

Description

The control circuit of clock energy-conserving road lamp

Technical field

The utility model relates to a kind of control circuit of street lamp, relates in particular to a kind of control circuit of energy-conserving road lamp.

Background technology

Street lamp is a part indispensable in people's daily life, and it provides road lighting for people, makes people's life more convenient, safety.But opening/closing of existing street lamp generally all is by the unified control of a certain administrative department, as staff's carelessness or control circuit fault is arranged, the risk that then exists street lamp not open or close, thus road lighting can't be provided or waste energy because of not closing street lamp.

Summary of the invention

The purpose of this utility model provides a kind of control circuit of clock energy-conserving road lamp, can open automatically or close at the time period control street lamp of setting, and realizes energy-conservation purpose.

To achieve these goals, the control circuit of the clock energy-conserving road lamp that the utility model provides, comprise the output module that is connected with street lamp, this output module is connected with control circuit, timer and comparator respectively, and this comparator also links to each other with control circuit and timer respectively; This output module also comprises output module and operating time output module at coupled night.

Further, described comparator is an analog comparator.

As seen from the above, the utility model is provided with timer and comparator in the control circuit of street lamp, can open and close street lamp automatically according to the different time that has configured, reaches purpose of energy saving, and can along with the variation of light by bright or by going out, humanized.

Description of drawings

Fig. 1 is a fundamental diagram of the present utility model.

Below in conjunction with accompanying drawing embodiment of the present utility model is done explanation in further detail.

Embodiment

The control circuit of clock energy-conserving road lamp of the present utility model, comprise the output module 4 that is connected with street lamp, output module 4 comprises output module 40 and operating time output module 41 at night, output module 4 is connected with control circuit 1, timer 2 and comparator 3 respectively, and comparator 3 also links to each other with control circuit 1 and timer 2 respectively, during work, control the output of switching time of street lamp and control light with strong and weak by the time that pre-sets timer 2.Simultaneously with reference to Fig. 1, the course of work of the present utility model is illustrated: for example the 7:00-18:30 with the every workday is set at the street lamp shut-in time, and timer 2 is in dormancy/operating state by the operating time output module 41 control street lamps of output module 4 in the time of appointment; Promptly in night and morning, the switch of street lamp can be lighted or extinguishes along with the 2 pre-set times of timer; The comparator 3 that adopts in the present embodiment is analog comparators, its control to light be by comparator 3 control output light what, the standard value of its setting is the cumulant of light, be comparator 3 also the opening/closing of output module 40 control at the night street lamps by output module 4 light gradually along with the variation of environment or extinguish gradually, not only provide illumination for the visitor, allow people feel the variation of surrounding environment, and more energy-conservation.

Comparator 3 is that an analog quantity voltage signal and one are compared with reference to fixed voltage, the two amplitude equate near, output voltage will produce transition, corresponding output high level or low level.Comparator can be formed the nonsinusoidal waveform translation circuit and be applied to fields such as analog and digital signal conversion.Thus, comparator can also adopt digital comparator, and whether be used for two groups of binary numbers of comparison identical, output (or low) high level when identical, otherwise, then export opposite level.Simple numerical comparator is a bit comparator, is an XOR gate (or with or door).

According to the utility model, timer and comparator are set in the control circuit of street lamp, can automatically open and close street lamp according to the different time, reach purpose of energy saving, and can along with the variation of light by bright or by going out, humanized.
