Try using a LDR (Light Dependent Resistor) as a sensor switch for it to shut down when the sun sets. There are existing design on web and just copy their designs and modifying it to satisfy your need. I'm an Electronics Engineer and now has a business of sellingink for printers. But still I can help you design your circuit. It's good to refresh my knowledge in designing circuit boards.

you can use a incandescent light bulb 5 or 10 bulbs you can use

Have you got the LEDs Sarfraz ?
