摘要:
An LED indication lamp has desired luminous intensity distribution characteristics without need for any light-emitting diode of a special shape. The LED indication lamp comprising a plurality of light-emitting diodes and having specified luminous intensity distribution characteristics is further provided with a condenser lens. The light-emitting diodes are arranged in a pattern corresponding to a luminous intensity distribution pattern determined according to the luminous intensity distribution characteristics. The light-emitting diodes thus arranged and the condenser lens are arranged so that light emitted from the light-emitting diodes in the luminous intensity distribution pattern through the condenser lens satisfies the luminous intensity distribution characteristics.

Electrophotographic transfer paper having a coating layer provided on at least one surface of base paper and pigments and adhesive agents as main components, wherein resistivity (VR) and surface resistivity (SV) of electrophotographic transfer paper after the humidity has adjusted to 10.degree. C., 30% RH for 12 hours satisfy the expression Log(VR/SR).ltoreq.1.5. Using such electrophotographic transfer paper, occurrence of discharge mark and occurrence of density irregularity in a high-density image region are prevented to thereby make it possible to provide electrophotographic transfer paper excellent in fixing characteristic, nonshowthrough, partial deletion and generation of paper dust.
