Description

A kind of long afterglow surface light source device of side entrance back
Technical field
It the utility model is related to extraordinary light emitting device field, and in particular to a kind of long afterglow area source device of side entrance back Part.
Background technology
Long after glow luminous material belongs to a kind of light-accumulating luminous material:It sends visible ray under the exciting of excitation source, and The part luminous energy of acquisition is stored;After exciting stopping, it slowly releases the energy of storage in the form of luminous energy.By In this characteristic, long after glow luminous material obtains in fields such as emergency lighting, fire-fighting life-saving, traffic security protections more and more should With.
Traditional long afterglow product is grown mainly using ambient light come inspired long-lasting phosphor, but in routine use Afterglow materials excite generally not enough fully, therefore brightness is relatively low, it is impossible to reach actual operation requirements.
Therefore, make the long afterglow that actively lights it has been proposed that long after glow luminous material is combined with active illuminating source Device, by controlling active illuminating source to be lighted with certain cycle or dutycycle interval come inspired long-lasting phosphor, from And the luminosity of long afterglow product is improved under low-power consumption.Again due to the particular advantages of LED light source, typically now preferably LED long-afterglow devices are made as excitation source in LED light source.
The existing common practices for actively lighting long-afterglow device is directly to set to excite in the bottom surface of long after glow luminous material Light source.The problem of so doing is:According to luminosity theory --- luminous intensity and distance square are inversely proportional, if long afterglow Luminescent material and actively excite the distance between spot light too near, then long after glow luminous material apart from actively excite spot light compared with Near region excites luminous energy superfluous, excites luminous energy insufficient what distance actively excited the region of spot light farther out, cause to grow more than Brightness luminescent material is excited uneven so as to forming hot spot;If long after glow luminous material and actively exciting distance between spot light too Far, decay occurs in way is propagated for exciting light so that exciting light can make full use of, and afterglow materials, which are stimulated, does not fill Divide and cause brightness relatively low.As patent No. CN205723621U propose a kind of long afterglow LED, in LED exciting lights Long after glow luminous material is directly set above source, is analyzed more than, overall luminosity can be caused not uniform enough;As having again People proposes a kind of solar LED long afterglow ball lamp, and long after glow luminous material, the top of ball lamp are equably mixed on ball lamp housing Portion sets solar energy photovoltaic panel, and the cavity center of ball lamp sets LED excitation sources, by solar energy photovoltaic panel to LED excitation sources Power supply and inspired long-lasting phosphor;Because LED excitation sources are spot light, therefore luminosity is not uniform enough;And LED swashs Light emitting source apart from long after glow luminous material too far so that exciting for long after glow luminous material is insufficient, and brightness is relatively low;It is and whole The cost of housing doping long after glow luminous material is too high.
Because the long-afterglow device that actively lights is the new things that just grew up in recent years, mostly in primary simple application It is stage, technically ripe not enough, therefore problems in every respect be present:Such as the luminous length of in general active in the market For twilight sunset device under the low-power LED shooting condition using regular size, the twilight sunset of long after glow luminous material maintains brightness general No more than 1cd/m2, the overwhelming majority is in tens to hundreds of mcd/m2Between, it is impossible to reach practical standard;Particularly some Product needs luminosity height, luminous area source uniform, purity of hone is good, energy standard batch produces, and using existing Technology is also difficult to reach above-mentioned requirements.
How existing actively light long-afterglow device non-uniform light is overcome, by exciting insufficient caused luminosity inclined Low and poor purity of hone technological deficiency, and the standard standardized product that modularized production obtains reliable in quality is formed, particularly The launching efficiency of light source and the after-glow brightness and purity of hone of long-afterglow material are further improved, so as to improve product quality and production Industryization is horizontal, into problem urgently to be resolved hurrily in the industry.
