Description
【０００１】[0001]
本考案は、白熱灯への供給電圧を下げることにより白熱灯を長寿命化した白熱 灯照明器具に関するものである。 The present invention relates to an incandescent lamp luminaire that extends the life of the incandescent lamp by lowering the supply voltage to the incandescent lamp.
【０００２】[0002]
従来より、白熱灯に供給される電圧を下げると白熱灯の寿命が大幅に伸び、 Ｌ＝Ｌ0 ×（Ｖ0 ／Ｖ）d という実験式が得られることは、よく知られている。ここにおいて、Ｖ0 は定格 電圧、Ｖはランプ電圧、Ｌ0 は定格寿命、Ｌは電圧Ｖでの寿命、ｄは約１３程度 の定数である。従って、白熱灯照明器具でランプ交換の頻度を少なくするために は、白熱灯への供給電圧を下げ、白熱灯の寿命を延ばせばよい。It has been well known that when the voltage supplied to an incandescent lamp is lowered, the life of the incandescent lamp is significantly extended and an empirical formula of L = L 0 × (V 0 / V) d is obtained. Here, V 0 is the rated voltage, V is the lamp voltage, L 0 is the rated life, L is the life at the voltage V, and d is a constant of about 13. Therefore, in order to reduce the frequency of lamp replacement in an incandescent lamp, the supply voltage to the incandescent lamp may be lowered to extend the life of the incandescent lamp.
【０００３】 ところが、白熱灯では、供給電圧が下がってランプ電圧が定格電圧より低くな ると、色温度が低下し赤っぽい光が照射されることになる。そのため、ランプ交 換の頻度を減らすというメンテナンス上の効果はえられても、定格電圧での色温 度に合わせて配慮されている照明効果を得ることができない恐れがあった。However, in the incandescent lamp, when the supply voltage decreases and the lamp voltage becomes lower than the rated voltage, the color temperature decreases and reddish light is emitted. Therefore, although the maintenance effect of reducing the frequency of lamp replacement is obtained, there is a risk that the lighting effect that is considered according to the color temperature at the rated voltage cannot be obtained.
