Abstract

Due to the highly complex nature of fluorescent lamp discharge, its electrical behavior and interaction with ballast can only be fully investigated and understood in the framework of a self-consistent model. Collisional-radiative modeling provides the capability to describe in details the microscopic reactions in the discharge on the basis of three groups of continuity equations: particle balance, electron energy and gas temperature. This paper discusses the formulation of these equations and later applies them to modeling the lamp's electrical behavior in a ballast environment. Prototypes of the conventional magnetic ballast and half-bridge LCC inverter ballast were constructed to verify the model accuracy. The self-consistency of the model has enabled the computer design of lamp ballast for any given lamp parameters, that is: lamp radius, wall temperature, buffer gas pressure, power supply voltage or current, frequency and power.
在自洽碰撞辐射模型的基础上对荧光灯的电气行为进行建模
由于荧光灯放电的高度复杂性,其电气行为和与镇流器的相互作用只能在自一致模型的框架内进行充分的研究和理解。碰撞辐射模型提供了在粒子平衡、电子能量和气体温度三组连续方程的基础上详细描述放电中微观反应的能力。本文讨论了这些方程的公式,并将其应用于模拟镇流器环境下的灯的电气行为。建立了常规磁镇流器和半桥LCC逆变镇流器样机,验证了模型的准确性。该模型的自一致性使计算机能够对任意给定的灯参数,即灯半径、壁温、缓冲气体压力、电源电压或电流、频率和功率进行灯镇流器的设计。
