Multilayered lighting device

摘要

A light device and a method of making the same. The light device having a casing, or body, in the form of a multilayered stack that includes a supporting base layer, a scattering layer above the base layer, and an outermost protective layer above the scattering layer. The light device further includes a lighting unit contained within the casing, for emitting light outside the light device. The multilayered stack of the casing may further include a spacer arrangement, either as a separate layer between the base layer and the scattering layer, or as an integrated arrangement of one or both of the base layer and the scattering layer. The outermost protective layer may also be a prism layer having a one-way light transmitting character, and a one-way light reflecting character. The bottom layer may include a fastening element for releasably fastening the light device to a separate mounting unit.

1. A light device comprising:
a multilayered stack comprising a supporting base layer, a spacer layer above the base layer, a scattering layer above the spacer layer, and a prism layer above the scattering layer; and a lighting unit comprising a power source, a light source, a switch, and a circuit electrically connecting the power source, light source, and switch, wherein the base layer of the multilayered stack comprises a fastening element on a bottom side for joining with a mating fastening element, the lighting unit is contained within the multilayered stack, below the scattering layer, the spacer layer comprises a recess dimensioned to receive the lighting unit in a manner to limit lateral movement of the lighting unit within the multilayered stack, the scattering layer is made of a light-transmitting material that diffuses light emitted from the light source, the scattering layer comprising a hole that extends entirely through the scattering layer, and the prism layer is made of a prismatic material having a one-way light-transmission character that allows light emitted from the light source to pass outside the multilayered stack, and having a one-way light-reflective character that reflects light originating from outside the multilayered stack.
