菊花電照省電方式之研究:最佳化之電燈架設

摘  要
 

   本文以物理光學上照度之計算,推估菊花進行電照時,在不同水平距離下之最佳電燈架設高度及平面配置,藉以節省電費。最佳架設高度為量測點至電燈水平距離除以 1.414 。若為矩形配置,正方形為最佳平面配置,而最佳架設高度為正方形邊長之半。考慮菊花之生長造成高度之減少,適宜高度為最佳高度加上 30 cm 。若以光量 ( 照度×時間 ) 為電照需求基準,提高架設燈泡密度及照度並減少照明時間,可以節省用電量。

關鍵字: 菊花、暗期中斷、電燈架設、最佳化 。

E nergy Saving in Chrysanthemum Night-break: Optimum Light Installation

ABSTRACT

   Light intensity is one of basic consideration of night-break in chrysanthemum commercial production. The optimum installing height of light and configuration calculated by physical and mathematical principle was described for saving energy. The optimum height of light is the horizontal distance between light and measured point divided by 1.414. The best arrangement for lighting area is a square if a rectangle area is used. Considering the growth of chrysanthemum, height will be reduced between light and plant. It was suggested adding 30 cm of optimum height as an appropriate height. If light amount is considered as a critical factor, increasing installation density and light intensity as well as reducing time of lighting could reduce energy cost.

Key words: chrysanthemum, night-break, light installation, optimum .
