常用裝飾藝術照明電光源之白熾燈

發(fā)布時間： 2020.02.29 來源：長沙裝修公司

白熾燈的發(fā)光原理是：當鴇絲通過電流時，產生大量的熱，使鈣絲溫度升高 2400 K-3000 K,達到白熾燈的程度。白熾燈產生可見光，用于照明。但白熾燈光的總量中只有15%左右可產生可見光，剩余能量以紅外線的形式輻射出去。其種類有普通白熾燈、反射型白熾燈、磨砂白熾燈以及石英燈等。其特點是：①高度的集光性和顯色性；②安裝簡便，適合于頻繁開關；③光效率低，壽命短；④受電壓波動影響較大。

由于白熾燈色溫在2700 K-3000 K,因此發(fā)出的光與自然光相比呈紅黃色，有溫暖感，常適用于家庭、賓館、飯店及藝術照明等，具有很強的實用性。但白熾燈的熱輻射較高，應注意光源的散熱性能。另外，白熾燈還有鹵鈣燈、碘鈣燈等多種形式
