Fig. 2 is master controller block diagram in the present invention.
Embodiment
In order to technological means of the present invention, creation characteristic, reach object and effect is easy to understand, below in conjunction with specific embodiment and diagram, set forth the present invention further.
As described in Fig. 1-2, a kind of solar domestic illuminator, it comprises solar panel, storage battery, master controller, DC/AC inversion control and lighting load, also comprise DC/DC conversion to control and voltage sample, described solar panel is connected with storage battery with relay switch by forward-biased diode, due to the discontinuity of sunlight, solar panel at night or overcast and rainy generating of having no idea, farthest can utilize sky sun energy by the design of forward-biased diode and relay switch.Described lighting load is connected by switch and civil power are for subsequent use, can tackle the defect of the electricity shortage that long-time continuous rainy weather causes, and ensures that illuminator is run safe and reliable.Described master controller comprises overcharge protection circuit, over-discharge protection circuit, load over-current protection circuit, anti-reverse charging protection circuit display circuit and temperature-compensation circuit; avoid damaging system unit etc. due to improper use; can guarantee that illuminator normally, reliably works, and effectively extend the useful life of whole system.
The input of described master controller is connected with voltage sample, and data are passed to master controller by the voltage be used in monitoring system.
The output of described master controller and DC/AC inversion control convert with DC/DC and control to be connected, because photovoltaic cell output voltage is unstable, can have an impact to back-end circuit like this, therefore first circuit is converted by DC/DC conversion control, carry out inversion by DC/AC inversion control again, obtain required stable alternating current.
Described overcharge protection circuit is connected with anti-reverse charging protection circuit with storage battery, display circuit, temperature-compensation circuit, and wherein anti-reverse charging protection circuit is directly connected with solar panel.
Described over-discharge protection circuit and storage battery and display circuit are in series.
Described over-discharge protection circuit also converts with current foldback circuit, DC/DC and to control and DC/AC inversion control is in parallel.
The inverter of self-excitation inverting inversion selected by described DC/AC inverter.
On daytime, solar panel receives the luminous energy of the sun and converts electric energy to, is stored in storage battery; At night, the transformation of electrical energy stored in storage battery becomes the 50Hz alternating current required for normal lighting for throwing light on by controller, thus reaches the object of energy-conserving and environment-protective.Due to the discontinuity of sunlight, solar panel at night or overcast and rainy generating of having no idea, so storage battery is connected together by forward-biased diode and relay switch and storage battery by one by native system design, farthest solar energy can be utilized.Because the capacity of storage battery can not maintain by long-time rainy weather again, therefore system disposition civil power is for subsequent use, the electricity shortage that the long-time cloudy weather for several days running weather of main reply causes.
In illuminator, solar panel directly can convert sky solar ray energy to electric energy; Storage battery can store the electric energy that solar cell provides, and uses for during needs; Master controller mainly ensures that illuminator normally, reliably works, extend the useful life of system unit (particularly storage battery), it comprises overcharge protection circuit, over-discharge protection circuit, load over-current protection circuit, anti-reverse charging protection circuit display circuit and temperature-compensation circuit, avoids damaging system unit etc. due to improper use; DC/AC inversion control and DC/DC conversion control, it is the AC DC electric direct current that solar panel and storage battery export converted to required for lighting load, because solar panel output voltage is unstable, can have an impact to back-end circuit like this, therefore first circuit is converted by DC/DC conversion control, carry out inversion by DC/AC inversion control again, obtain required stable alternating current.And selecting of lighting load also will consider the problem with DC/AC inversion control Proper Match, i.e. the voltage and current waveform of reasonable design filament preheating time and excitation fluorescent tube.Reasonably preheating filament will extend the useful life of lighting load effectively, and the method that preheating filament adopts has the pipeline start up by preheating such as filament series connection starter, filament series relay, thermistor preheating filament.
Under the effect of controller, solar panel is to charge in batteries, and evening, storage battery supplied electrical power to load.Controller comprises overcharge protection circuit, over-discharge protection circuit, load over-current protection circuit, anti-reverse charging protection circuit display circuit and temperature-compensation circuit etc.; can under any condition; guaranteeing that storage battery can not be destroyed because overcharging or excessively put, farthest utilizing sunlight.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand, and the present invention is not restricted to the described embodiments, and without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
