In this paper, we consider the problem of designing energy efficient light emitting diodes (LEDs) layout
while satisfying the illumination constraints. Towards this objective, we present a simple approach to the
illumination design problem based on the concept of the virtual LED. We formulate a constrained optimization
problem for minimizing the power consumption while maintaining a near-uniform illumination throughout
the room. By solving the resulting constrained linear program, we obtain the number of required LEDs and
the optimal output luminous intensities that achieve the desired illumination constraints.
