在以往气体放电和电弧技术的基础上，等离子体技术得到迅速发展，照明学者为了满足节能减排对大功率照明的要求，一直致力于将无极放电等离子体应用于照明领域。高频无极放电灯是应用电感耦合等离子体技术的一种新型电光源，影响无极灯光效的因素较多，但无极灯的光效与Hg253．7nm谱线有直接的关系，Hg253．7nm谱线的相对强度I253.7nm可以作为光效的参考量。通过测量不同放电条件研究了等离子体电特性对Hg253．7nm谱线的强度的影响，实验研究发现随频率的增加，253．7nm辐射强度先迅速增加，然后缓慢增加且趋于平稳；随放电功率的增加，253．7nm辐射强度先增加后下降；随填充气体Ar气压增加，253．7nm紫外辐射先增加后减小。该实验结果为提高无极灯功率和光效提供依据。

On the basis of the gas discharge and arc technology, plasma technology has been developing rapidly, in order to meet the requirements of energy-saving high-power lighting. High-frequency electrodeless discharge lamp, a new type of electric light uses inductively coupled plasma technology. The luminous efficiency of electrodeless lamp is directly related to the efficiency of Hg253.7 nrn resonance spectrum lines. We experimentally studied the glowing characteristics of electrodeless lamp, and found that, with discharge frequency increasing, Hg253.7 nm radiation intensity first increased rapidly, then increased slowly and tended to he stabilized; with discharge power increasing, Hg253.7 nm radiation intensity first increased and then decreased; with the pressure of Ar increasing, Hg253.7 nm ultraviolet radiation first increased and then decreased. The experimental results provide a basis to improve the power and luminous efficiency of the discharge lamp.
