In an incandescent bulb, if there is no phosphor coating the glass, the filament produces a very glaring light that is painful to look at directly. The phosphor takes the light of the filament and turns it into a more even, and less glaring glow.

What is the toxic chemical inside cathode ray tubes?
Cadmium, Phosphor material and Lead coated glass of CRT that's so TOXIC.
Is it dangerous to break fluorescent light bulbs on your back if you drain the mercury?
Yes, and not just because of the glass it is made of. The bulbs have mercury inside of them which can make you ill.
Are sodium light bulbs made of glass?
Yes, Sodium bulbs have a glass center piece and a glass bulb surround.
What is the structure inside the nuclus that contains genes?
DNA, which looks like an hour glass.
Why is glass used to make electric bulbs?
Glass is used in light bulbs because it's clear (passes the light through), can withstand the heat generated by the filiment and does not leak air to the inside of the bulb. And, it's cheap and easily formed into the required shape(s)
What is a person that makes glass bulbs called?
A person who makes glass bulbs is called a glassblower or a glass artist specializing in glass blowing techniques. They use a combination of heat, tools, and blowing techniques to shape molten glass into various forms, such as bulbs.
What are light bulbs made out of?
glass and such
The light-producing element in a fluorescent bulb is the?
Light in fluorescent bulbs occurs when electricity excites the mercury vapor inside the tubular glass bulb.
What type of glass is used for light bulbs?
glass with powder coating
How does fluorescent work?
Fluorescent lights glow because of an electric discharge in a glass tube that causes mercury atoms to emit ultraviolet light. The inside of the tube is coated with phosphor, which absorbs the ultraviolet light and then re-emits visible light.
Who makes glass bulbs in Edison's time?
Haydyvd
What are light bulbs made of?
Incandescent light bulbs (those with a filament inside them) use a tungsten wire inside a glass envelope. Tungsten is used because it has a very high melting point so it can glow brightly without melting. The gas inside the glass envelope is used to prevent burning and so extend the life of the filament.A different answerA fluorescent lamp is a gas-discharge lamp that uses electricity to excite mercury vapor in argon or neon gas, resulting in a plasma that produces short-wave ultraviolet light. This light then causes a phosphor to fluoresce, producing visible light.More informationFor a very simple looking product, the light bulb is the result of a huge amount of research and development. This description is simplified but there it is worth reading more about light bulb technology for more information.
