Description:
BACKGROUND OF THE INVENTION 
       [0001]    (a) Field of the invention 
         [0002]    The lamp driving circuit of power source and charge/discharge device in parallel connection is disclosed by that: 1) At the preparation status of no power output to drive the lamp, the charge/discharge device is charged by an AC to DC power to maintain a good electricity storing status; 2) At parallel output status of power output to drive the lamp, the power output of charge/discharge device and AC to DC power jointly drive the lamp. Said preparation status of no power output to drive the lamp and said lamp being driven by the parallel output appear a stable periodical variation such as applications for nightly outdoor lamps, road lamps, advertising lamps, nightly warning lights, etc. are based on periods of days and nights, wherein during daytime it is at the preparation status of lamps off, the charge/discharge device is charged by the AC to DC power and during nighttime, the lamps are commonly driven by a parallel combined power output of the AC to DC power and the charge power from the charge/discharge device; further, an auxiliary type random power generator device can be optionally installed as needed such as a solar energy generation device or a wind power or hydraulic power generator device to randomly charge the charge/discharge device. 
         [0003]    (b) Description of the Prior Art 
         [0004]    The charge/discharge device such as batteries, super-capacitors, etc. are usually used as a reserved power source to power the lamps, however, when the lamps are required to be driven by a larger periodic or intermittent power, if the capacity of the charge/discharge device is enlarged so as to power the lamp by the charge/discharge device alone, the cost is higher and said charge/discharge device is required to work at a larger electric current which affects the battery life, in addition, a charge/discharge device of larger power capacity have to be used simultaneously in order to match with the charge/discharge device of larger capacity, resulting in a waste of resources and cost increase; 
         [0005]    Furthermore, if the lamps are parallel connected for powering by extension cords of the circuit, the lamp lightness is disadvantageously affected due to voltage drop at terminal end of extension cord. 
       SUMMARY OF THE INVENTION 
       [0006]    The lamp driving circuit of power source and charge/discharge device in parallel connection is disclosed to appear a preparation status and a parallel output status which are operated and controlled manually or by an environment light and darkness detector device or a timing device, or by a built-in control mode of the central control unit with reference to detected signals by a charging status detector circuit, or reference to the control or detected signals by said light and darkness detector device or timing device, wherein the circuit includes that at preparation status of lamps off, the AC to DC power is charged to the charge/discharge device, and at parallel output status, the AC to DC power and discharged power from charge/discharge device are combined to commonly drive the lamps. As discharged power of charge/discharge device and AC to DC power are parallel connected to drive the lamps, a smaller installed capacity of said charge/discharge device can be selected and the power capacity of transformer device and circuit devices for AC to DC rectification can also be relatively reduced, further when electricity generation of the optionally installed auxiliary type random power generator devices of solar power generator devices, wind power or hydraulic power generator devices, etc. is insufficient to charge the charge/discharge device completely, the charge/discharge device can also be charged by AC power.

         [0139]    As summarized from above descriptions, said lamp driving circuit of power source and charge/discharge device in parallel connection is by installing a charge/discharge device ESD 100 , the relevant charge control devices and an isolated diode for use in the following: 
         [0140]    (1) The charge preparation status in which the AC power is converted to a DC power; and 
         [0141]    (2) The parallel output status in which said two powers are parallel connected to commonly drive the lamps. 
         [0142]    Due to daytime on and nighttime off period of said lamps, said lamp driving circuit of power source and charge/discharge device in parallel connection can be embodied by that during daytime, the AC to DC power is charged to said charge/discharge device ESD  100 , and during nighttime, the lamps L 100  are commonly driven by the parallel output of the AC to DC power and the discharged power of said charge/discharge device ESD 100 , so that required power capacity of the device for voltage change and current rectification can be reduced and the required charging capacity for the charge/discharge device ESD 100  is also reduced to lower the cost and save resources. In addition, said charge/discharge device ESD 100  can be installed at terminal ends of extension cords, so that the disadvantages of too much voltage drop at terminal ends of extension cords can be avoided when multiple lamps are parallel connected by long extension cords.
