成都霓虹發光燈帶特點:
霓(ni)虹燈是一(yi)種特殊的低壓冷陰極(ji)輝光放電(dian)(dian)電(dian)(dian)光源。與其他弧光燈不同(tong),霓(ni)虹燈是在(zai)高壓電(dian)(dian)場作用下,通過玻(bo)璃管中填充的低壓惰性氣體發光的。
霓虹(hong)(hong)(hong)燈(deng)的(de)光(guang)(guang)色是由(you)惰性氣(qi)體(ti)的(de)光(guang)(guang)譜特(te)性決定的(de):霓虹(hong)(hong)(hong)燈(deng)充滿氖氣(qi),霓虹(hong)(hong)(hong)燈(deng)發出(chu)紅光(guang)(guang);熒(ying)光(guang)(guang)霓虹(hong)(hong)(hong)燈(deng)充滿氬和汞(gong),霓虹(hong)(hong)(hong)燈(deng)發出(chu)藍色和黃色的(de)光(guang)(guang)。這兩種霓虹(hong)(hong)(hong)燈(deng)是通(tong)過(guo)燈(deng)管中工(gong)作氣(qi)體(ti)原子的(de)受激輻射發光(guang)(guang)的(de)。
