Abstract

A solar charging torch is characterized in that illumination light source which is composed of a reflector and a high-brightness white light-emitting diode group is arranged on the top of the torch, which has the advantages of big brightness, long irradiation distance and long service life, the torch is provided with a single-crystal silicon photo-voltaic cell with a protecting cover, when the torch is turned on, solar energy is utilized to charge the torch, so that the electric power is saved, when the torch is turned off, increase of the reflectance which is coursed by the pollution of the surface, the effect to the photovoltaic effect and damages of accidents are avoided, a nickel-hydrogen battery is used as a power supply, poisonous elements such as cadmium, lead, hydrargyrum and the like are not contained, and the torch is beneficial to health and environment protection, especially is suitable for using in travelling, field operations, night outgoing in area without power supply and is used for lighting during safeguarding on duty.

Description

The solar charging electric torch

Affiliated technical field

The utility model belongs to ligthing paraphernalia, and especially the portable lighting utensil is made the field.

Background technology

The employed rechargeable battery of commercially available chargeable electric torch, as ickel-cadmium cell and the storage battery formula battery formed by sulfuric acid-lead, though can repeatedly use but in charging, still expend many electric power resources, can't use in the place that does not have power supply especially, this class battery all contains infringement health and the heavy metal that causes environmental pollution simultaneously, as materials such as mercury, cadmium, lead.

Along with living standard, the raising of health, environmental consciousness, existing flashlight can not satisfy the illumination needs of people's daily life and special occasions.

Summary of the invention

Can't use in the place that does not have power supply for solving existing chargeable electric torch, and the deficiency that contains hazardous substance in the battery, the utility model provides a kind of solar charging electric torch of being made power supply by Ni-MH battery.

The technical scheme that its technical problem that solves the utility model adopts is: be provided with a cap, dustproof glass and one at the top of torch by reflection shield, high brightness white hair optical diode group, the lighting source formed; be used for night illumination; both sides, stack shell middle part are provided with over cap and are installed in monocrystalline silicon photovoltaic cell on the over cap, over cap can along with the combination of stack shell machinery after active section open, close.

Power supply is supplied with also available other rechargeable battery by the Ni-MH battery group that is arranged in the stack shell.

Monocrystalline silicon photovoltaic cell, charge controller, rechargeable battery, power switch, current limiter, high brightness white hair optical diode group are electrically connected in proper order, after adopting Ni-MH battery to make power supply, this battery does not contain poisonous elements such as cadmium, lead, mercury, can not work the mischief to healthy and environment, simultaneously because the Ni-MH battery volume is little, capacity is big, can reduce the volume of flashlight.

During charging the both sides over cap opened and make the monocrystalline silicon photovoltaic cell, after having charged over cap is closed, can prevent that monocrystalline silicon photovoltaic cell surface from because of the contaminated reflectivity that increases, influencing photovoltaic effect and unexpected failure in the face of sunlight.

The beneficial effects of the utility model are: by reflection shield and high brightness white hair optical diode group; the lighting source brightness of forming is big; irradiation distance is far away; life-span is long; the monocrystalline silicon photovoltaic cell that has over cap; utilize solar recharging to save electric power resource during unlatching; can prevent when closing increases reflectivity because of the surface is subjected to polluting; influence photovoltaic effect and unexpected failure; adopt Ni-MH battery to make power supply; do not contain cadmium; plumbous; poisonous element such as mercury is beneficial to health and environmental protection, is specially adapted to tourism; going out night in field work and non-transformer area, on dutyly guards illumination and use.
