Abstract
The utility model relates to a solar energy road lamp automatic lighting device which comprises a photocell, an accumulator, a control switch and a lighting lamp, wherein, the photocell is connected with the positive pole of the accumulator by a diode. A lighting loop is composed of the accumulator, the control switch and the lighting lamp, and the control end of the control switch is connected with the positive pole of the photocell. The high electric level and the low electric level of the control end causes a switch to be respective in a cloing state and an opening state. During day, solar energy is converted into electric energy by the photocell, and the accumulator is charged by the diode. At night, a control switch is closed, the accumulator supplies electricity for the lighting loop, that is, the lighting loop is switched on by the control switch. The utility model has the advantages of simple structure, high safety and electric energy saving, and is suitable for lighting road lamps at office buildings, house buildings, etc.
Description
The utility model relates to a kind of street lighting device that solar energy converting is become electric energy.
At present, the stair of nearly all building, the illuminating lamp in the corridor is powered by AC network, and by mechanical switch control, crosses and make troubles for the night pedestrian way, if use altar lamp, has caused great energy waste again.
In order to address the above problem, the utility model provides a kind of solar street light automatic illuminating apparatus, and street lamp can throw light on automatically after the darkness, can make things convenient for the pedestrian, but saves energy again.
The utility model is achieved in that it comprises photocell, storage battery, control switch and illuminating lamp, photocell is in parallel with storage battery by diode, storage battery, control switch and illuminating lamp are formed lighting loop, control switch is a light-operated switch, control end links to each other with photocell is anodal, and the high and low level of control end is in switch respectively and closes and open two states.Its operation principle is: during daytime, photocell is exposed to sunlight, and luminous energy is changed into electric energy and charges a battery by diode, and simultaneously, control switch disconnects lighting loop; When the evening draws on, the control switch closure was connected lighting loop, and storage battery discharges to lighting loop, and illuminating lamp is lighted.
The utility model utilizes Solar Street Lighting System to throw light on automatically, has both saved electric energy, makes things convenient for the pedestrian at night again, and simple in structure, safe and reliable, can be used for the office building of enterprises and institutions, the street lighting of residential building etc. and the illumination of the extra exit of heavy construction.
Fig. 1 is the utility model block diagram.
Fig. 2 is the utility model circuit theory diagrams.
Embodiment is described in detail the utility model below in conjunction with accompanying drawing:
By shown in Figure 1, the utility model is made up of photocell 1, storage battery 2, light-operated switch 3 and 4 four parts of street lamp, its circuit theory as shown in Figure 2, it is in parallel with storage battery 2 that photocell 1 passes through diode D1, makes photocell can unidirectionally charge to storage battery.Storage battery connects into lighting loop by light-operated switch and street lamp, and light-operated switch is made up of triode Q1 and Q2 second amplifying circuit and relay J.The a pair of normally-closed contact of relay J is connected on the lighting loop, relay coil is connected between the collector electrode and ground of triode Q2, the base stage of Q1 is a control end, link to each other with photocell is anodal, be connected to voltage-stabiliser tube W between the emitter of Q1 and the ground, between the current collection collection and ground of triode Q2, the diode D2 of a reversal connection also in parallel damages Q2 with the induced voltage of avoiding coil blackout moment generation.In the time of by day, photocell 1 is exposed to sunlight, and luminous energy is converted into electric energy, and positive pole has voltage signal, Q1, Q2 conducting, and coil electricity, normally-closed contact disconnects, and lighting loop is disconnected, and photocell charges to storage battery 2 by diode D1 simultaneously; When the evening draws on, the voltage of photocell positive pole was zero, and Q1, Q2 close, coil blackout, and normally-closed contact closes, and lighting loop is connected, and illuminating lamp begins illumination.
For saves energy, also can connect the acoustic control delay switch at each lighting sub loop, like this, at photocontrol at night switch lighting loop is connected, when the pedestrian sent the sound, the acoustic control delay switch was connected lighting sub loop, and illuminating lamp is luminous, and close automatically after time-delay a period of time, can more effectively utilize solar energy to give a plurality of branch road power supplies.
Claims (3)
1, a kind of solar street light automatic illuminating apparatus comprises: photocell, storage battery, illuminating lamp, and storage battery and illuminating lamp are formed lighting loop; It is characterized in that: the photocell positive pole links to each other with battery positive voltage by diode; Be connected to control switch on the lighting loop of storage battery and street lamp composition, control switch closes and opens two states with being in respectively night by day.
2, automatic illuminating apparatus according to claim 1 is characterized in that control switch is a light-operated switch, and its control end links to each other with photocell is anodal, and the high and low level of control end is in switch respectively and closes and open two condition.
3, lighting device according to claim 1 and 2 is characterized in that also being connected on each lighting sub loop acoustic control system delay switch.
