Claim:
An illuminating device with adjustable light beams, comprising: a substrate; multiple light-emitting units disposed on the substrate; an optical element disposed in the path of a light emitted by at least one of the light-emitting units; and a driving unit driving a first or second set of the light-emitting units, wherein a light beam formed by light that is emitted by the first set of the light-emitting units and passes through the optical element has a different shape or projection angle from a light beam formed by light that is emitted by the second set of the light-emitting units and passes through the optical element; wherein the light beam formed by the light that is emitted by the first set of the light-emitting units and passes through the optical element has a different intensity from the light beam formed by the light that is emitted by the second set of the light-emitting units and passes through the optical element.
