Opto Engineering提供光(guang)(guang)強(qiang)度(du)控制(zhi)(zhi)器(qi)作為附件，可(ke)精確(que)調(diao)整各(ge)種照(zhao)(zhao)(zhao)明(ming)燈(deng)(deng)的(de)(de)光(guang)(guang)強(qiang)度(du)。任何機(ji)器(qi)視(shi)覺應用(yong)(yong)(yong)(yong)(yong)都采用(yong)(yong)(yong)(yong)(yong)某種光(guang)(guang)控制(zhi)(zhi)器(qi)。燈(deng)(deng)光(guang)(guang)控制(zhi)(zhi)器(qi)廣泛用(yong)(yong)(yong)(yong)(yong)于(yu)優(you)化照(zhao)(zhao)(zhao)明(ming)強(qiang)度(du)并獲得(de)燈(deng)(deng)光(guang)(guang)和視(shi)覺相(xiang)機(ji)之(zhi)間可(ke)重(zhong)復的(de)(de)觸發順(shun)序。該控制(zhi)(zhi)器(qi)是緊湊型(xing)單元，旨在(zai)用(yong)(yong)(yong)(yong)(yong)于(yu)計算機(ji)視(shi)覺中的(de)(de)連續(xu)，低閃爍(shuo)的(de)(de)照(zhao)(zhao)(zhao)明(ming)應用(yong)(yong)(yong)(yong)(yong)。它包括(kuo)電(dian)(dian)源調(diao)節和電(dian)(dian)流(liu)強(qiang)度(du)控制(zhi)(zhi)。使用(yong)(yong)(yong)(yong)(yong)前(qian)面板(ban)可(ke)訪問的(de)(de)4向DIP開關(guan)，根(gen)據(ju)燈(deng)(deng)光(guang)(guang)規格選擇輸出(chu)電(dian)(dian)流(liu)的(de)(de)范圍(wei)。然后，可(ke)以(yi)使用(yong)(yong)(yong)(yong)(yong)前(qian)面板(ban)旋鈕或(huo)外部模(mo)擬0-10 V調(diao)光(guang)(guang)信號來調(diao)節輸出(chu)電(dian)(dian)流(liu)。邏輯0-24 V使能(neng)輸入可(ke)用(yong)(yong)(yong)(yong)(yong)于(yu)打(da)開和關(guan)閉連接的(de)(de)燈(deng)(deng)。提供0-24 V邏輯故障輸出(chu)以(yi)指示(shi)過(guo)(guo)熱或(huo)故障。除(chu)了使用(yong)(yong)(yong)(yong)(yong)4向DIP開關(guan)，前(qian)面板(ban)旋鈕和上(shang)述三個離散信號之(zhi)外，還(huan)可(ke)以(yi)通過(guo)(guo)PC使用(yong)(yong)(yong)(yong)(yong)集成的(de)(de)串(chuan)行RS485或(huo)以(yi)太網接口完全設置(zhi)控制(zhi)(zhi)器(qi)。配置(zhi)保存(cun)在(zai)非(fei)易失性(xing)存(cun)儲器(qi)中，以(yi)便控制(zhi)(zhi)器(qi)在(zai)重(zhong)啟(qi)后恢復運行。輔(fu)助熱傳感器(qi)輸入可(ke)用(yong)(yong)(yong)(yong)(yong)于(yu)感應光(guang)(guang)線溫度(du)（如果光(guang)(guang)線中有熱傳感器(qi)可(ke)用(yong)(yong)(yong)(yong)(yong)）。輔(fu)助風扇(shan)輸出(chu)可(ke)用(yong)(yong)(yong)(yong)(yong)于(yu)為外部冷卻風扇(shan)供電(dian)(dian)（如果照(zhao)(zhao)(zhao)明(ming)設備中有風扇(shan)）。

大(da)多數LED制(zhi)造商建議使用恒(heng)定(ding)電(dian)(dian)(dian)流源而(er)不(bu)是恒(heng)定(ding)電(dian)(dian)(dian)壓(ya)源來驅動(dong)其產品。這是因為，使用恒(heng)定(ding)電(dian)(dian)(dian)壓(ya)驅動(dong)時，LED上溫度(du)或電(dian)(dian)(dian)壓(ya)的(de)微小變化會(hui)導致(zhi)其亮(liang)(liang)度(du)發生明顯變化。由于亮(liang)(liang)度(du)隨電(dian)(dian)(dian)壓(ya)的(de)非(fei)線(xian)性，用電(dian)(dian)(dian)壓(ya)進行(xing)亮(liang)(liang)度(du)控(kong)(kong)制(zhi)也非(fei)常困難。相(xiang)反，亮(liang)(liang)度(du)與(yu)電(dian)(dian)(dian)流近似成線(xian)性關系，因此(ci)通過(guo)以已(yi)知(zhi)電(dian)(dian)(dian)流驅動(dong)LED，強度(du)控(kong)(kong)制(zhi)呈線(xian)性關系。該數字控(kong)(kong)制(zhi)器具有單個可(ke)編程的(de)，電(dian)(dian)(dian)流控(kong)(kong)制(zhi)的(de)連續輸出，電(dian)(dian)(dian)流范圍為零至4A。
