Fig. 2 illustrates the circuit theory sketch map of luminous energy charger as shown in Figure 1.
Embodiment
With reference to the accompanying drawings, specific embodiments of the invention is done further to describe in detail.
Fig. 1 illustrates the structure composition frame chart according to the luminous energy charger of one embodiment of the invention.With reference to Fig. 1, be applicable to that the luminous energy charger that battery is carried out charging operations comprises charging module 10, battery pack 12, voltage stabilizing didoe 14 and charging indication 16 at least.Specifically, charging module 10 is electrically connected to battery pack 12.Battery pack 12 has multiple batteries, and for example, these batteries are connected in series, and battery pack 12 electrically connects voltage stabilizing didoe 14 and charging indication 16.Wherein, the battery in the battery pack 12 can be a disposable battery, such as smee cell; Also can be rechargeable battery, such as nickel-cadmium cell or Ni-MH battery.Voltage stabilizing didoe 14 is connected in parallel with battery pack 12, and the voltage that is used for that battery pack is loaded remains near the rated voltage of battery.Charging indication 16 is connected in parallel with battery pack 12, is used for after the charging process of battery pack is accomplished, and the output index signal has been full of voltage to show battery pack.For example, this index signal comes from a LED light, when LED light is lighted, explains that the charging operations of battery pack is accomplished.
Fig. 2 illustrates the circuit theory sketch map of luminous energy charger as shown in Figure 1.Should be pointed out that Fig. 2 just schematically explains the circuit theory of luminous energy charger of the present invention, but be not limited to the model or the number of the electronic component among the figure.With reference to Fig. 2, charging module 10 comprises a plurality of infrared receiving diode D1-D50, and the type and the electrical parameter of these infrared receiving diodes are identical.In order to obtain consistent charging voltage, for example, can infrared receiving diode D1-D50 be divided into five groups or five branch roads fifty-fifty; Promptly first group is D1-D10, and second group is D11-D20, and the 3rd group is D21-D30; The 4th group is D31-D40, and the 5th group is D41-D50.In addition, can know from Fig. 2 that the infrared receiving diode in each group is connected in series, and adopt and be connected in parallel between each group.
For instance; Suppose that single infrared receiving diode is 0.3V to 0.4V because of receiving the forward voltage that illumination produced among Fig. 2; The electric current of flowing through is 0.3mA to 0.4mA; And the charging voltage of the primary silver zinc battery that two joints are connected in series is approximately 3V (1.5V*2), and charging current is approximately 1.5mA to 2.0mA.According to rule of the voltage in series circuit and the parallel circuits and electric current rule, charging voltage is substantially equal to the voltage value of each parallel branch in the charging module, and charging current is substantially equal to the current values sum of each parallel branch in the charging module.So, during charging module, the parallel branch number is 5 in design, i.e. 1.5mA/0.3mA (or 2.0mA/0.4mA), and the infrared receiving diode number in each parallel branch is 10, i.e. 3V/0.3V.Be that infrared receiving diode D1-D50 shown in Figure 2 is divided into 5 groups fifty-fifty, each is organized interior 10 infrared receiving diodes and is connected in series.In addition, if the capacitance of primary silver zinc battery to be charged is 80mAH, calculate with charging current 1.5mA to 2.0mA, accomplishing charging process then needs 40 hours to 50 hours.Should be pointed out that because the voltage stabilizing function of voltage stabilizing didoe Dz can remain on the charging voltage of battery pack 12 about 3V, meet predetermined requirement.
In another embodiment of the present invention; If battery to be charged is a rechargeable battery, battery pack 12 is the rechargeable battery (nickel-cadmium cell or Ni-MH battery) that two joints are connected in series, and its charging voltage is approximately 2.4V (1.2V*2); Charging current is 150mA; The capacity of rechargeable battery is 1200mAH, and H equals 1.5*1200/150 the charging interval so, promptly 12 hours.For charging voltage 2.4V, can luminous energy charger shown in Figure 2 slightly be changed.For example; First kind of solution is; Reduce the infrared receiving diode number that each parallel branch comprised in the charging module; If single infrared receiving diode is 0.3V to 0.4V because of receiving the forward voltage that illumination produced, then can the infrared receiving diode number of each parallel branch be reduced to 8 by 10.Second kind of solution is; Keep the infrared receiving diode number in the charging module constant; With the voltage stabilizing parameter setting of voltage stabilizing didoe Dz is 2.4V; Thus, even the charging voltage that produces through charging module is 3V, but voltage stabilizing didoe Dz still is stabilized in charging voltage 2.4V with the voltage at battery pack 12 two ends.And be 150mA for its charging current of rechargeable battery, then can realize through increasing infrared receiving diode parallel branch number.
In Fig. 2, also be provided with a charging indication 16 and be connected in parallel with battery pack 12, be used for output LED index signal after charging process is accomplished.For example, this charging indication 16 is series connection branch roads, and it is made up of divider resistance R and light-emitting diode D51, D52, D53 and D54.Those of ordinary skill in the art should be appreciated that these light-emitting diodes just begin after the electric current of flowing through reaches certain numerical value luminous, designs the deixis suitable resistance value R can satisfy the charging completion so.
In the another embodiment of the present invention, between charging module 10 and battery pack 12, also comprise K switch, be used to start or close the charging operations of luminous energy charger.In addition, this K switch can also connect by open circuit after charging is accomplished.
Adopt luminous energy charger of the present invention; The forward voltage that infrared receiving diode is produced when accepting illumination is as the micro photo electric pond; Thereby battery pack is carried out charging operations; This luminous energy charger not only can make the capacitance recycling of disposable battery or rechargeable battery, can also energy savings.In addition, the electric current of the infrared receiving diode of flowing through is very small and weak, when battery pack is charged, can't damage battery because of current values is excessive.
In the preceding text, illustrate and describe embodiment of the present invention.But those skilled in the art can understand, and under situation without departing from the spirit and scope of the present invention, can also specific embodiments of the invention do various changes and replacement.These changes and replacement all drop in claims of the present invention institute restricted portion.
