20090129104 | Floor mat - A conventional room lamp or foot lamp has a problem that the place where user's feet are is difficult to see and poor in visibility, and on the other hand, when the lamp is made unnecessarily bright to cause luminance distribution in the field of view to be discontinuous, an unpleasant phenomenon called glare occurs. A surface EL light emitting body is entirely coated with a transparent waterproof sheet and then it is sandwiched and bonded between upper and lower sheets to form on mat. At least a part of the upper sheet is formed transparent, a lead wire is fixed to the EL light emitting body, and a connector to be connected to a power supply outlet in a vehicle is provided at the forward end of the lead wire. A light control circuit for altering the emission intensity of the EL light emitting body and a circuit for automatically turning off the power upon disconnection of the lead wire are provided in the middle of the lead wire, and the EL light emitting body is made to emit light at a luminance of 0.5-4.0 cd/m | 05-21-2009 |
