Abstract:
1. A lamp having a planar light-emitting source comprising: a plate-shaped light-guiding structure having at least one light-emitting plane, a rear plane and a plurality of side planes, each side plane being substantially perpendicular to said light-emitting plane, said rear plane is disposed with a reflecting portion, a thickness of 1 mm to 10 mm being between said light-emitting plane and said rear plate; a light-emitting portion having an electric circuit portion and a plurality of point-shaped lighting units; said light-emitting portion emitting a plurality of point-shaped light beams toward at least one predetermined side plane; a shading supporting seat for securing said light-guiding structure and receiving said light-emitting portion; so that said point-shaped lighting units emitting a plurality of point-shaped light beams, through said corresponding side plane and then entering said light-guiding structure, turning substantially 90 degrees to emit a uniform planar light from said planar light-emitting source, wherein said light-guiding structure is disposed with a plurality of optical micro-structures, and wherein said shading supporting seat is connected to a portable folding lamp, said portable folding lamp including: a horizontal plate having a thickness between 1 mm to 20 mm; a vertical plate having a thickness between 1 mm to 20 mm. two opposite ends of said vertical plate being pivoted with two pivoting portions for connecting with said shading supporting seat and said horizontal plate; so that said carrying lamp seat has a folding condition with a total thickness smaller than 50 mm.
