Starters are classified by principle of operation
Various gas discharge light source starters can be divided into three categories according to the working principle. 1 In the discharge lamp circuit or in the structure of the discharge lamp, measures are taken to reduce the ignition voltage of the discharge lamp, and the discharge lamp is turned on under the action of the power supply voltage or a higher voltage generated in the circuit. The characteristics of this type of starter are: not necessarily a device acting as a starter, but multiple devices or the entire circuit can function as a starter. For example, some fluorescent lamp starters and high pressure mercury lamp starters. 2 In the discharge lamp circuit, there is a separate circuit part as the starter, which generates a higher pulse voltage and is applied to both ends of the discharge lamp, and the lamp is started to light up under the action of the power supply voltage. The parameters of this type of starter are: pulse voltage peak, pulse voltage width, rise time of pulse front, pulse voltage in the phase range of power supply voltage and energy. For example, a high pressure sodium lamp starter. 3 In the discharge lamp circuit, there is a separate circuit part as the starter, which generates intermittent high-frequency voltage and is applied to both ends of the discharge lamp. Under the joint action of the power supply voltage, the lamp is started to light up, which is also called high-frequency high-voltage start-up. Device. The parameters of this type of starter are: high frequency voltage peak, high frequency, repetition frequency and energy of intermittent oscillation. Generally, a discharge lamp having a high ignition voltage (up to tens of thousands of volts) uses such a starter. For example, a short arc xenon lamp starter and a partial metal halide lamp starter.
