1. An apparatus comprising:

  • a flexible substrate to which a plurality of light sources are fixed;

    a flexible substrate housing in which the flexible substrate is located;

    wherein the flexible substrate is comprised of a peripheral region and a center region;

    and further comprising a flexing device for flexing the flexible substrate by applying pressure to the center region of the flexible substrate to cause the flexible substrate to deform;

    and wherein in a first state when the flexible substrate is not deformed by the flexing device, each of the plurality of light sources emits light which is concentrated in a first direction;

    and wherein in a second state when the flexible substrate has been deformed by the flexing device, at least one of the plurality of light sources emits light which is concentrated in a second direction which differs from the first direction; and

    wherein the flexible substrate housing is comprised of a removable holder and a case;

    wherein the flexing device is comprised of the removable holder and the case;

    and wherein the removable holder can be connected onto the case; and

    and wherein the connecting of the removable holder onto the case can cause the flexible substrate to deform.
