A lighting apparatus comprises a light panel having a panel frame, and a
plurality of LEDs or other light elements secured to the panel frame.
Lenses and/or filters are adjusted in distance from the light elements,
by for example moving the lenses/filters into different slot positions of
the frame, to alter characteristics of the emitted light. Focal lenses,
diffusion lenses, and color filters may be used individually or in
combination. A compound lens includes lens elements having different
characteristics arranged in a pattern. Through groupwise control of the
intensity of the light elements, the different characteristics are
emphasized or de-emphasized. The light panel may have an integrated
battery, and may be be mounted on a stand. The panel may be modular,
allowing larger panels to be constructed from smaller panels.
