A hot toaster is luminous because it emits visible light as a result of its high temperature. When the toaster's heating elements reach a certain temperature, they begin to glow due to incandescence, which is the process of emitting light from heat. This occurs because the thermal energy excites the atoms in the metal, causing them to release photons in the visible spectrum. Thus, the glow is a byproduct of the energy being converted from electrical to thermal, and then to light.

Is it possible for a toaster to convert light energy to heat energy if not what energy would it convert?

A toaster takes in electricity from some power source, then it uses this electricity to heat coils within the toaster. The coils get very hot, and emit heat in the form of electromagnetic radiation (light). The bread/bagel/sock that you put into the toaster absorbs this radiation and gets hot.
