The working principle of a tube light is based on the flow of electric current through a gas-filled tube. The tube is coated with a phosphor layer that emits visible light when excited by the electric current. The gas inside the tube helps to facilitate the flow of electrons, resulting in the emission of light.
A tube light does not have a filament like an incandescent bulb. Instead, it uses a gas-filled tube coated with a phosphor layer. When electricity is passed through the gas, it ionizes the gas and excites the electrons, causing them to emit ultraviolet light. The phosphor coating then converts this ultraviolet light into visible light that we can see.
The starter in a tube light helps to initiate the flow of electric current through the gas-filled tube. When the switch is turned on, the starter provides a high voltage pulse that ionizes the gas inside the tube, allowing the current to flow and light up the tube. Once the current is flowing, the starter is no longer needed and the tube light stays lit until the switch is turned off.
A tube light and an LED light both use electricity to produce light, but they differ in the technology they use. A tube light uses a gas-filled tube and a phosphor coating to emit light, while an LED light uses a semiconductor material that emits light when current passes through it. LEDs are more energy-efficient and have a longer lifespan compared to tube lights.
Yes, the color of light produced by a tube light can be changed by using different phosphor coatings on the tube. The phosphor coating determines the color temperature of the light, with cooler temperatures appearing more bluish and warmer temperatures appearing more yellowish. Some tube lights also come with color-changing features, allowing users to adjust the color of light according to their preference.
