Description
Technical field
The utility model content belongs to the technology of semiconductor illumination application field, relates to the LED navigation light or the aviation obstruction beacon of the AC-battery power source assembly power supply that a kind of employing is made up of photovoltaic cell, ultracapacitor and ferric phosphate lithium cell.
Background technology
Marine greatly in the great river, in order to prevent that the naval vessel from hitting a submerged reef or stranded, the navigation light of the signal that must setting can flash is with thinking indication course, passing naval vessel.In the skyscraper field, bump in order to prevent buildings such as airborne aircraft and high-rise building, television tower, communication iron tower, also must be at can the flash aviation obstruction beacon of signal of the disconnected installation in these buildings top.The electric power system that this class flash lamp of past all adopts photovoltaic cell and battery to form is with incandescent lamp as light source.Because when flash of light took place incandescent lamp, the transient pulse electric current was very big, in order to satisfy the requirement of instantaneous large-current pulsed discharge, just must select the very big battery of capacity for use, so system cost is very high; Because incandescent lamp often is in flash state, and reduce service life greatly, therefore need often to change again, maintenance cost increases.
The utility model content
The purpose of this utility model is to solve at the subject matter that prior art exists, and provides that a kind of novel structure, cost are low, long service life, LED navigation light or aviation obstruction beacon by ultracapacitor and supplying power for photovoltaic cell that power savings is good.
The technical solution that adopts is so to achieve the above object of the invention: provided by the LED navigation light of ultracapacitor and supplying power for photovoltaic cell or aviation obstruction beacon by photovoltaic cell, storage battery charge controller, ultracapacitor and ferric phosphate lithium cell mixed power supply system are formed with the LED lamp array that is built-in with the constant-current discharge control circuit, storage battery charge controller connects and is located between photovoltaic cell and ultracapacitor and the ferric phosphate lithium cell mixed power supply system, and the power end of ultracapacitor and ferric phosphate lithium cell mixed power supply system adds on the working end that is connected on LED lamp array.In the real work, photovoltaic cell to ultracapacitor and the charging of ferric phosphate lithium cell mixed power supply system, provides constant impulse discharge current by the constant-current discharge control circuit for the high-powered LED lamp array by ultracapacitor and ferric phosphate lithium cell mixed power supply system by storage battery charge controller then.
Compared with prior art, one of characteristics of the present utility model are to have adopted semi-conductor lighting lamp (LED) technology that has obtained developing rapidly application in recent years.The major advantage of LED has that power savings is remarkable, luminous intensity is high, the power of monomer led light source can reach more than the 200W at present, it successfully has been applied to aspects such as street lamp, garden lamp, military high light torch, test through domestic authoritative optical research, with compare with the power incandescent lamp, the luminous intensity of LED lamp is more than 13 times of incandescent lamp, compares with the electricity-saving lamp with power, and the luminous intensity of LED lamp is more than 3 times of electricity-saving lamp.The advantage that has again of LED is to use the life-span long especially, and its theoretical life-span can reach 100,000 hours, and also surpass 50,000 hours actual life, for incandescent lamp and electricity-saving lamp tens times even up to hundred times; To light speed very fast for the LED lamp in addition; almost there is not time delay; and group flashing light had no effect to the life-span; furthermore accomplish scale production so far owing to LED; the cost of product reduces greatly, so it is specially adapted to require long-life, high energy-conservation flash of light navigation light or aviation obstacle flash lamp.In order to guarantee enough luminous intensities, led light source of the present utility model can be formed array by series-parallel system by many led chips.
Another characteristics of the present utility model are to have adopted the mixed power supply system of being made up of photovoltaic cell, ultracapacitor and lithium iron phosphate storage battery.Ultracapacitor is the novel energy storage device of a kind of performance that had just grown up in recent years between battery and ordinary capacitor, its energy density (Wh/kg) exceeds more than 10 times than conventional capacitor, power density (W/kg) is tens times of conventional accumulators, even hundred times, need to be specially adapted to the electronic equipment (such as flash lamp) of heavy-current discharge pulse.Ultracapacitor allows quick charge, usually can be in 1～2 minute full charge, the discharge cycles number of times of ultracapacitor can reach 10 simultaneously
5, be the hundred times of conventional accumulators even several thousand times, by the mixed power supply system that super capacitor and battery compose in parallel, both can bring into play the advantage that accumulator capacity is big, cost is low and can power for a long time, also can realize the requirement that super-large current discharges and recharges.Ferric phosphate lithium cell also is just to begin the novel storage battery used in recent years, it have security performance good, have extended cycle life, volume is little, advantage such as in light weight, cycle life can reach 3500 times at present, the overdischarge ability of overcharging is also strong especially, AC-battery power source with the ultracapacitor composition, can reduce the volume and weight of navigation light and aviation obstruction beacon greatly, also can increase the service life greatly.
After the utility model adopts above-mentioned design, because LED lamp power demand reduces greatly, and ultracapacitor can provide the super large pulse current, the luminous intensity of having guaranteed the LED flash lamp is up to state standards, therefore, the capacity of required photovoltaic cell and battery can descend significantly, and system cost reduces greatly; Simultaneously because the time delay of lighting a lamp of LED flash lamp is extremely short, and when being operated in flash state, the life-span is unaffected, battery is with after ultracapacitor is in parallel, and pulse high current is mainly provided by ultracapacitor, also can prolong the life-span of battery greatly.
