I want to make this texture emit light but only from the lamp. I make a glow shader than what? If i will add in shader - q3map_surfacelight  it will be on the whole texture . How to make it only from the lamp?

You'd need to have the "bulb" surface as its own texture afaik.

AAaaa You mean add in shader a line : Surfaceparm bulb ?

[Ramikad]

I think he meant the bulb part to be a completely different part from the texture, with a specific shader to emit light.

Yeah, the q3map_surfacelight setting affects an entire surface (as the name suggests). You need to separate your shaders (and brushes) into a wall shader and a light shader.

You could have an overlay texture as part of the shader with cull twosided and q3map_alphashadow, if youre not worried about extra rendering passes.
