Yes, law of conservation of energy is strictly followed in interference phenomenon. Of course there is redistribution of energy but there is no net loss or gain of energy in accordance with the conservation law of energy.

Is the law of conservation of energy obeyed by interference phenomenon of light?

Yes, the law of conservation of energy is obeyed in the interference of light. While energy is redistributed between constructive and destructive interference regions, the total energy across the entire interference pattern remains constant. No energy is created or destroyed in the process.
