<P>PROBLEM TO BE SOLVED: To provide a floor light emitting device preventing uncomfortable feeling even when a user is in contact with a floor part by preventing the floor part from being heated while maintaining brightness of the floor part at a desired value. <P>SOLUTION: The floor light emitting device 1 includes the translucent floor part 2, and a light source part 3 for emitting light from the floor part 2. The floor part 2 includes a flow channel 21 for running a cooling fluid L1 for cooling the floor part 2 with temperature raised due to heat generated from the light source part 3. Because the floor part 2 is cooled by the fluid L1, the temperature rise of the floor part 2 is suppressed. Therefore, the floor part 2 is not heated and the user does not feel uncomfortable even when the user is in contact with the floor part 2. In addition, it becomes unnecessary to reduce an emitted light amount of the light source part 3 and suppress an amount of heat generation in order to prevent uncomfortable feeling even when the user is in contact with the floor part 2, and the brightness of the floor part 2 can be maintained at the desired value. <P>COPYRIGHT: (C)2010,JPO&INPIT |
