光電的轉化率特別稀缺,所以光對新農村太陽能路燈來講特別珍貴,為了更大化的利用好每一寸光,景觀燈生產廠家小編一直在研究將光型合理利用,減少道路外光的浪費。終研發出zhuanli透鏡,對光線進行二次配光,讓光線與道路平行,提升了光的利用率。家都知道新農村太陽能路燈是新能源的照明產品。在現實照明中,既可以節省經濟開支、節省能源,還能夠提高效率,這些對于新農村太陽能路燈來說至關重要。鑒于此,推薦景觀燈的(de)(de)(de)光(guang)源(yuan),也(ye)就(jiu)是我們(men)熟稱的(de)(de)(de)燈頭(tou)就(jiu)非常重要了。首先,新農村太(tai)陽能路燈的(de)(de)(de)燈頭(tou)應該(gai)使用鋁制壓(ya)鑄(zhu)或者抗沖擊擠壓(ya)生產,堅固硬度和重量的(de)(de)(de)權衡才好(hao)。再就(jiu)是,為了保證壽命在出廠前應該(gai)進行機械(xie)振動的(de)(de)(de)測試,以便保證燈頭(tou)的(de)(de)(de)質量。當然,為了光(guang)源(yuan)可以穩定(ding)的(de)(de)(de)工作。要做良好(hao)的(de)(de)(de)散熱設計,防塵、防水應該(gai)達到IP65。
