A high voltage is required when the lamp starts to ignite, and only a small current is allowed to pass during normal illumination, when the voltage across the lamp is lower than the supply voltage. This high voltage is provided by the bubble we usually say. When the power is turned on, since the two metal pieces in the bubble of the starter are not turned on, the power supply breaks through the xenon conduction. At this time, we see that the bubble emits light, and the helium gas generates heat when it is conductive, causing the bimetal in the bubble. (that is, the one we saw bent) The curvature is reduced after being heated, and the two electrodes are turned on at the same time, and a large current is passed. The high voltage required to start the fluorescent lamp is reached. After that, since the helium in the bubble is no longer conductive and emits light after the bimetal is turned on, the temperature drops rapidly, the bimetal returns to the original state, and the power is quickly cut off, and the current of the ballast suddenly changes from a large value to 0, resulting in Very high self-induced electromotive force, this self-inductive voltage is enough to break through the mercury vapor of the fluorescent lamp, so that the mercury vapor ionizes and emits ultraviolet light to stimulate the fluorescent powder to emit light. After the fluorescent tube is electrically conductive, the voltage across the fluorescent tube decreases (about 100V). This voltage can no longer make the bubble conductive (the breakdown voltage of the bubble is about 150V) and emit light, and the bimetal is no longer connected. At this time, the fluorescent lamp can continuously emit light.

A spring lock washer, also known as a split lock washer, is a type of fastener used to prevent loosening or rotation of a bolt or nut. It is made of a circular metal ring with a split cut along one side, creating a spring-like effect.

When a spring lock washer is placed between the head of a bolt or nut and the surface it is being tightened against, the washer exerts a spring force that helps to keep the fastener in place. This force creates friction and prevents the bolt or nut from loosening due to vibrations or other external forces.
Spring lock washers are commonly used in various industries and applications where secure fastening is required, such as automotive, construction, and machinery. They are available in different sizes and materials, including stainless steel, carbon steel, and brass, depending on the specific requirements of the application.
