Light absorbing and light emitting devices, light admitting assemblies, and methods of absorbing and emitting light

A light absorbing and light emitting device, comprising:

• a first structure;
• and
• a holder,
• the first structure is supported by the holder,
• at least a first portion of the first structure has a first side,
• the first portion of the first structure comprises at least one phosphorescent material or at least one phase change material,
• the first structure is movable relative to the holder at least between a first structure first position and a first structure second position,
• in the first structure first position, the first side of the first portion faces a first direction,
• in the first structure second position, the first side of the first portion faces a second direction,
• the first direction differs from the second direction,
• the holder is rotatable about a first holder axis, and
• rotating the holder about the first holder axis causes the first structure to wrap completely around the holder in a plurality of windings.

A light absorbing and light emitting device, comprising:

• a first structure;
• a holder;
• at least a first bracket;
• and
• at least a first stop,
• the first structure is supported by the holder,
• at least a first portion of the first structure has a first side,
• the first portion of the first structure comprises at least one phosphorescent material or at least one phase change material,
• the first structure is movable relative to the holder at least between a first structure first position and a first structure second position,
• in the first structure first position, the first side of the first portion faces a first direction,
• in the first structure second position, the first side of the first portion faces a second direction,
• the first direction differs from the second direction,
• the first bracket and the holder define a first structure-retaining region through which the first structure extends and in which it is slidably retained,
• the first stop is attached to the first structure, and
• the first stop, the first structure, the first bracket and the holder are shaped, sized and oriented such that the first stop is prevented from passing through the first structure-retaining region upon sliding movement of the first structure relative to the first structure-retaining region.
