You have quite a few options. The easiest would probably be to simply increase your EV value. EV stands for exposure value, and will allow you to quickly make the scene brighter or darker as you wish. On your Nikon D7000, the button is denoted by a +/- symbol and it is located right next to the shutter release button and on/off button on the top of the camera. Just select that button, and use your scroll wheel to increase the brightness(+1,+2,+3) or decrease the brightness(-1,-2,-3). Technically this is called increasing or decreasing the exposure.
If you have a scene that has a very bright light source(the sun) as well as dark shadows, this might beyond the capabilities of your camera sensor to capture it with a single exposure. This is where HDR photography can come in handy. It allows you to capture a scene at multiple different exposure values, and combine it into one image.
A third option would be to change the metering mode that you are using. If you are in P mode I am guessing that is set to automatic or some type of evaluative metering of the entire scene. You can test out spot metering, where you are only evaluating a small portion of the scene for the correct exposure. I am not sure if the D7000 allows you to do this in P mode or not, but take a look at the manual and see where it talks about metering modes, and that should give you a good place to start.

After reviewing the image, I think your main issue here is the metering mode. Try switching that up to see how your results differ. You could easily setup a scene like this in your own house to test the differences.
In response to this comment "What I can do to make light source be darker and the rest of dark scene be brighter?":
As others have stated, this is beyond the capabilities of your camera sensor. Your camera simply cannot expose the very bright bulb and the foreground at the same time. HDR is your friend in this case.
