Lighting apparatus with adjustable lenses or filters

An illumination system comprising:

• a light panel comprising a panel frame;
• a plurality of semiconductor light elements disposed on the panel frame;
• and
• an adjustable lens system for altering a characteristic of the light emitted by the semiconductor light elements, said adjustable lens system providing different beam spread angles for said semiconductor light elements through a user-activated electronic control;
• wherein said light panel is adapted for being mounted to a movable camera apparatus, a stand, or a yoke.

An illumination system, comprising:

• a light panel comprising a panel frame;
• a plurality of semiconductor light elements disposed on the panel frame;
• and
• an adjustable lens system for altering a characteristic of the light emitted by the semiconductor light elements, said adjustable lens system comprising a first plurality of focusing elements for altering the light emitted by a first group of said semiconductor light elements and a second plurality of focusing elements for altering the light emitted by a second group of said semiconductor light elements;
• wherein said first plurality of focusing elements and said second plurality of focusing elements provide different color temperature characteristics for the emitted light;
• and
• wherein said first plurality of focusing elements and said second plurality of focusing elements are disposed in a checkerboard pattern.
