Photoluminescent light bulbs

Photoluminescent light bulbs, also known as glow-in-the-dark light bulbs, are a type of lighting technology that uses phosphorescent materials to emit light without the need for electricity.

These bulbs work by absorbing and storing energy from ambient light or other light sources, such as incandescent or LED bulbs. The phosphorescent material inside the bulb then emits this stored energy as a soft glow, even after the light source has been turned off.

The technology behind photoluminescent light bulbs is based on the principle of photoluminescence, which is the emission of light from a material after it has absorbed light. In the case of these light bulbs, the phosphorescent material is typically a type of rare earth element or a mixture of phosphors that are designed to emit light in a specific color or wavelength.

Photoluminescent light bulbs are often used in emergency lighting applications, as they do not require a power source and can continue to emit light for several hours after the power has been cut.

Carbon filament light bulbs

Carbon filament light bulbs are a type of incandescent light bulb that uses a carbon filament to produce light. These bulbs were first developed in the late 1800s and were widely used in homes and businesses until the 1920s, when they were largely replaced by more efficient types of bulbs.

The carbon filament in a carbon filament bulb is made by heating a strand of carbonized bamboo or other plant material until it becomes charred and black. The resulting filament is then wound into a coil and placed inside a glass bulb that is filled with an inert gas, such as nitrogen or argon, to prevent the filament from burning up.

When an electric current is passed through the filament, it heats up and begins to glow, producing light. The color of the light produced by a carbon filament bulb is determined by the temperature of the filament. At lower temperatures, the light is more orange or yellow, while at higher temperatures it is more white or blue.

Carbon filament bulbs are known for their warm, amber-colored light, which is often associated with vintage and Edison-style bulbs. However, they are not very energy-efficient and have a relatively short lifespan compared to other types of bulbs, which has led to their decline in popularity in recent years.
