( 1) SCR 【 SCR ( 可控硅整流器) SCR for short, is a kind of high-power electrical components, also known as the thyristor. 】 As electronic switch, the switch status in addition to inspect the size of the yue into the trigger pulse, and outside, also take decisions on the size of the thyristor trigger level itself. When the line in the change of working voltage, temperature changes and the thyristor in the manufacturing process of discreteness and other reasons, the switch status will bring a lot of randomness, thus produced by high pressure can not be well controlled, its peak in the 2000 V - high pressure Button, differences between 5000 v. ( 2) Trigger at work, Iw frequency high pressure itself. If for some reason, the device can't quit the job, so, no matter for auxiliary parts of lamps and lanterns, and itself can not stand the impact of the high frequency high voltage test for a long time. ( 3) Trigger itself produces high frequency high voltage, in the case of trigger long distance, the distributed capacitance on the circuit of high frequency energy absorption is big, so high pressure drops rapidly, and high pressure sodium lamp cannot be for a long and reliable ignition. In sodium initial stage of popularization and application of the trigger the various ills caused by the failure to fully recognize and the circuit is relatively simple steam, use very convenient also, ballast type can also be use to replace mercury lamp ballast. And therefore has a certain use value, but because the trigger often damage, other auxiliary parts because of the trigger is often damaged, also the service life of high pressure sodium lamp will not improve. A couple of these to use department with production units are responsible for a lot of trouble. In the production of light bulbs single think our bulb is good, but too much for such a long the impact of high pressure, production unit of the ballast stone to their ballast breakdown often burned, then work on improving stress levels. And production can't afford to see sometimes sodium lamp ignition trigger unit, and in improving its high voltage output, the result is a contradiction between these three have been intensified. Of the total, making the high pressure sodium lamp on the promotion of use is limited greatly.
