<P>PROBLEM TO BE SOLVED: To provide a double-sides light-emitting device which is lightweight, in a simple structure. <P>SOLUTION: The light-emitting device 1 has a plurality of LEDs 7 arranged along one side face of a case, and has a reflective face 11 on the other side face. An optical element 8 is arranged in the light-emitting direction of the LED 7, and designated directivity is given to emitting-light of the LED. The emitting-light of the LED 7 is directly discharged outside via a front-surface light-emitting section (diffusion plate 4) and a rear-surface light-emitting section (diffusion plate 5) of the case, or is discharged outside, after it is reflected once by a reflective surface 11 or a side face of the case. <P>COPYRIGHT: (C)2010,JPO&INPIT |
