FIELD OF INVENTION
The present invention is directed to a hand cranking lamp for automobile. This invention relates to a light source which can be charged by hand cranking to be used in automobile. More particularly, the present invention provides hand cranking charging for a light source as well as the battery of the vehicle and vice -versa.
BACKGROUND & PRIOR ART
In the field of automobile, rechargeable battery technology has become increasingly important. Users of such devices rely on the batteries to be charged so that the device may be used throughout, in all locations. Typically, batteries are charged using a conventional outlet (e.g., 120 volts AC) and a transformer with a cord that connects to the device and sometimes in connection with a "docking station" or similar base used to recharge the battery of the device.
A problem occurs when the battery requires charging and the user cannot access a conventional power supply. In an emergency situation, it is particularly important for the user to be able to charge the vehicle battery so as to avoid the risk of security.
US publication no 20080157712 relates to a holder and battery charger system for portable electronic devices comprises a back panel and a releasably detachable front panel. The back panel itself comprised of a plurality of integrated sources of power for charging a device. Amongst the plurality of integrated sources of power for charging a device are: a flip out AC plug. A slide out USB connector slides out from within the back panel. A car plug and a car plug sheath attached to the side of the back panel.

Further objects and advantages of this invention will be more apparent from the ensuing description when read in conjunction with the accompanying drawing and wherein:
Fig 1 shows the block diagram of a hand cranking lamp for automobile according to the present invention.
DETAIL DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWING:
Reference may be made to fig. 1, which shows the block diagram of an improved manually-operated lamp 1 with a battery charger which can be used by a vehicle in emergency situations while travelling. The lamp 1 is charged through hand cranking and used to charge the vehicle's battery. Lamp can be charged through the battery of the car as well as hand cranking or grid power and in emergency situation hand cranking lamp can charge the battery of the vehicle. The lamp 1 according to the invention comprises a multidirectional DC/ DC converter with controller (2) which is interfaced with the battery (3) of the vehicle, hand held and rectifier section (4), AC/ DC converter (5), constant current source with charge storage device to drive light source 6 and communication interface 7 with the external device. The communication interface is connected to the external interface device 9 (hand held device with display). The controller 2 receives and stores the battery 3 information. The communication interface 7 receives the information from controller 2 and forwards it to the user's handheld device 9 (external device with display).
In one embodiment, the crank assembly includes a drive mechanism that couples the crank assembly to the rotor component. The drive mechanism is connected to a rotor and rectifier section 4 which converts mechanical energy into electrical energy controlled by the controller 2. The controller 2 forwards this energy to the battery 3 of the vehicle during the requirement. Alternately, this is fed to the output of the lamp 1 through constant current source with charge storage device to drive light source 6 if required.

The present invention has real time management using communication media or hand held device for remote monitoring. The user can monitor the status of the battery of the vehicle using a hand held device and can charge vehicles battery accordingly. The device displays battery parameters and gives audible alarms when the charge of the battery of the vehicle goes below a predetermined level.
It is to be understood that the above-described embodiments are illustrative of only a few of the many possible specific embodiments, which can represent applications of the principles of the invention. However, numerous and varied other arrangements can be readily devised in accordance with these principles by those skilled in the art without departing from the spirit and scope of the invention.
