I am a noob at blender and I created this scene(work-in-progress), and the study Lamp will be the only light source.

enter image description here

However, the light is filling the room and doesn't look realistic.

I want the bulb in the lamp holder to only emit light at the table(directional) and I don't know how to achieve this. have a look at this image to know what I mean:

enter image description here

The bulb is only emitting light at the bottom and top(since it is open) and no light is emitted like in my image(except soft light)

In a nutshell, how do I make the bulb throw light only at the table, like a spotlight? I want the rays visible.

EDIT: The first is my render. The second is an example image from google to better explain what I want.

  • What type of Lamp are you using ? this is a job for Spot Lamp for it emit light in a cone shape. – Venay Mar 16 '17 at 10:25
  • maybe start with using a real light bulb ? –  Mar 16 '17 at 10:40
  • @Venay I am using a material to emit light. UV Sphere. – 4-K Mar 16 '17 at 11:17
  • @OldMan i don't understand. – 4-K Mar 16 '17 at 11:17

    @4-K, UV sphere is good here in the principle. What is the issue exactly from that? Using Cycles, right? – lemon Mar 16 '17 at 11:29
  • And @OldMan is right: a lamp (point) is faster – lemon Mar 16 '17 at 11:46

    Try moving the sphere further back in the lamp itself, and maybe scaling it down. Remember, the actual light emitter in a real-life bulb is rather small, so just experiment with it until you get satisfactory results. – Josh Silveous Mar 16 '17 at 11:47
  • @lemon Yes, Cycles. I want the light to only strike the table. Like the light effect from a torch. In my render the light is appearing to be emitted FROM the table and enlighting the whole room. There is no rays visible from the source. – 4-K Mar 16 '17 at 12:48
  • @JoshSilveous The sphere is small and I have moved it farthest in the lamp. :( – 4-K Mar 16 '17 at 12:49

    First, make the world texture completely black, so that you have no "environment" lights. Then make the light surce a point light and make the size = zero. Then start bringing the intensity to a high value. For a realisitic look you might need to use the "Filmic Blender" http://blender.stackexchange.com/questions/46825/render-with-a-wider-dynamic-range-in-cycles-to-produce-photorealistic-looking-im –  Mar 16 '17 at 14:11

    @4-K Then I would recommend just changing the emitter to a standard light. Perhaps you could provide us your .BLEND using this website? We could do some tinkering and see if we can figure out how to solve your problem – Josh Silveous Mar 16 '17 at 14:37
  • It worked now. I had to just turn off the environment light and move the sphere even further back up. Thanks all – 4-K Mar 16 '17 at 14:47

With a "point" light as lamp and a fabric texture with translucent shader for the lampshade.

enter image description here

The point light is just a light (as suggested by OldMan in the comments):

The lampshade is composed of a fabric texture and a translucent shader:

"No more"... if you try replacing the point lamp by a sphere, this is working too, but the render is slower and more noisy.

    I would add to this response information about Filmic Blender https://www.youtube.com/watch?v=53m-17Y_zJg – elmo Mar 16 '17 at 18:42
