Here is a quick tutorial to obtain some rays of light like the ones radiating from the star of the below Christmas tree:
Star Christmas tree
Start with a blank square document. It is important for the document to be square in order to generate the correct shaped star.
Select the needed colors for the star (foreground and background).
In the top menu go to Filter->Sketch->Halftone Pattern. Make contrast max (50) and Pattern Type to line. Make sure the size you choose is large.
Again in top menu go to Image -> Rotate Canavas -> 90CW (clockwise) and then crop the image to a square if it is not already square.
Now it’s time to make the stripes a star. To do that go to Filter -> Distort -> Polar coordinates (select Rectangular to polar).
Depending of the use you can appy more effects, for example I used two masks to create the fade.
