“How do fluorescent light bulbs work?”
All around the world, conventional filament-based light bulbs are being phased out in favor of this technology called fluorescent light bulbs. However, what exactly are these devices and how do they work? Well, let’s use our engineering mindset to find out. All electrical devices start with two components, an anode and a cathode. Now, electrical lights work by passing a current through the anode and cathode to generate current. Fluorescent light bulbs use a most ingenious way to accomplish this, instead of using a current to heat up a wire, the ends of the electrodes are separated by a mercury-containing gas. When electrons are passed through this material, they will collide with the mercury atoms which will become “excited” and release ultraviolet rays. The tube that connects both electrodes will be coated in a special coat that absorbs the dangerous UV rays and releases safe white light, therefore providing safe and efficient lighting. Fluorescent bulbs can produce between 50 and 100 lumens per watt., making them four to six times more efficient than incandescent bulbs
