1. A first device, comprising:
- a support;
a first substrate movably coupled to the support and movable between a first position and a second position;
a plurality of lighting devices disposed on the first substrate, wherein the plurality of lighting devices comprises a first portion of lighting devices and a second portion of lighting devices, andan energizing component, wherein the energizing component is configured to selectively energize the first portion and the second portion of lighting devices based on a position of the first substrate relative to the support,wherein the support comprises a housing that is provided with an opening, through which the first substrate is received and through which the first substrate is movably coupled to the support, whereby the first substrate can be retracted into or pulled out of the housing, through the opening, between the first position and the second position, thereby the housing is configured to selectively contain or expose the first and second portions of the lighting devices disposed on the first substrate,wherein the energizing component is configured to energize the first portion when the first portion is not contained within the housing, and to not energize the first portion when the first portion is contained within the housing.
