Background technology
Along with deepening continuously and the expansion of people's lives spatial dimension of reform and opening-up, China associates more frequent in international and domestic society, economy and politics etc., more needs the social overall situation of a peace and stability.Simultaneously, mass action and life style more and more diversified, masses' contradiction and standard of living will be on the rise, and this equips explosion-proof work and army and police and has proposed requirements at the higher level, will inevitably strengthen the demand with equipment to army and police.In addition, along with the day by day attention of modern society to new forms of energy and green technology, also the development to army and police's equipment has proposed new demand and new challenge.
For a long time, army and police with high high light torch (or portable illuminator) need labyrinth, larger volume, than heavy amount and high energy consumption design etc., just can put into practice, there are much inevitable technical vulnerabilities, as carry defectives such as trouble, use clumsiness, short, the easy inefficacy of lighting hours, cost height, life-span weak point.Bring numerous inconveniences for user and manager, also increased a unnecessary difficult problem (as frequent replacing dry cell, repeat purchase, the wasting of resources, management waste, environmental issue etc.) to logistics support.
Conventional portable army and police generally are made up of battery or dry cell, switch, optical reflector and lighting source four parts with high high light torch.This four part is encapsulated in a portable integral body or separate type metal or the plastic casing by different way, and generally operation principle is simple.Battery or the dry cell (or being called disposable dry cell) used with torch as traditional high strength army and police, if improper use, then often corrode electrical equipment and cause expensive electrical equipment damage, malfunctioning.Dry cell is various in style, internal resistance is big, because memory effect often causes the essence performance of dry cell capacitance to reduce.The cost height, difficulty of recycling dry cell be big, it is low to produce effects.With regard to volume and quality, discarded dry cell is inappreciable in house refuse, but its harm is very big.Contain heavy metal substances such as mercury, cadmium, lead in the dry cell, mercury has strong toxicity, and lead can cause neurological disorders, ephritis etc., and cadmium causes injury of kidney and bone disease one osteoporosis, rickets and fracture.If arbitrarily abandon scrap dry battery or it is sneaked in the house refuse landfill together, in the course of time, its heavy metal that oozes out may polluted underground water and soil, will endanger the healthy of people directly or indirectly.Scrap dry battery is also very big to the harm of environment, and compole is long during harm.The use amount of dry cell in our life increases sharply, and has been deep into each corner of our live and work.To the recovery and the processing of old and useless battery, not the problem of an area or country, but the common difficulty that the whole mankind faces.But effective solution is to use no or little to have the dry cell that pollutes character, is controlled on the source or stops from polluting.
Conventional portable army and police generally are filament bulb (as incandescent lamp, krypton lamp, Halogen lamp LED and xenon lamp etc.), fluorescent lamp (fluorescent lamp, electricity-saving lamp), arc lamp or plasma lamp etc. with the luminous and lighting source that high high light torch adopts.The light source of filament bulb mainly is to be provided and the electric energy of the tiny and fragile filament of flowing through by non-renewable power supply (as dry cell), its temperature is reach a certain height and a hot transform light energy takes place and form, fraction can be converted into luminous energy and luminous lighting but have only very, and most valuable electric energy (80%～90%) slattern with the form of heat energy.Fragile tungsten filament more is subject to foreign impacts power (as dropping on the ground) and ruptures.The service life of filament also very short (usually less than 500～1000 hours), and through being everlasting it is scrapped because of fracture before burning out naturally.As adopting fluorescent lamp as light source, its starting voltage is often higher with high high light torch for conventional portable army and police, and service life is also shorter, contains noxious material or gas simultaneously, also causes environmental pollution and harm humans health easily.
