A light bulb is not a change in and of itself but the process by which it gives off light is physical. While an electric current causes a given component of the bulb to glow (it may be the filament of an incandescent bulb or the vapor in a fluorescent one), but that substance does not change its chemical identity.

Is turning on a light bulb on a physical or chemical change?
The reason why turning on a light bulb is a physical change is because there is a process of electrical energy being converted into light and heat. You still have the light bulb intact and no new substance is formed.
Is turning a light bulb on a chemical change?
No.
Is electric bulb glowing a example of chemical or physical changes?
It is a physical change. When you supply electricity, the electrons jump to higher energy state. When they come back to their level, it emits energy which falls in the visible region of light. The atoms of the filament (Tungsten) are not going through any change, that changes their chemical properties. Tungsten, still remains tungsten!

No.
Is a filament of a light bulb glows when an electric current flows through it is a chemical change?
It is a physical change brought about by the exitation of molecules producing heat and light. A general rule of thumb is that a physical change can be repeated on an article and chemical change cannot. Remove the current from a filament and it is still a filament.

Did a chemical change take place in a light bulb?
Possible oxidation of the metallic filament with traces of oxygen existing in the light bulb.

Does a light bulb convert light in to chemical energy?
No a light bulb does not use chemical energy. Even though it uses the chemical mercury to create light. Hope this helps =)
