Title:
VEHICULAR LIGHTING FIXTURE
Document Type and Number:
Japanese Patent JPH10109587
Kind Code:
A
Abstract:

To provide such a vehicular lighting fixture that there is no fear of separation of a resistance heating element installed on the surface of a front lens.

In a vehicular lighting fixture equipped with a vesseled lamp body 9, a luminous source installed in this lamp body 9, and a front lens 18 assembled in a front opening part 9a of the lamp body, the said luminous source is composed of luminescence, while a resistance heating element (FPC heater 30) is made so as to be installed in at least one side of both inner and outer surfaces of the front lens 18, and a heating value of the luminescence is small as compared with that of an incandescent bulb, so that this resistance heating element (EPC heater 30) will in no case be separated by the heat generation of this luminescence. In addition, snow thawing and defogging actions by the heat generation of this luminescence are not expected, but these actions are carried out by the heat generation of the resistance heating element (FPC heater 30), whereby there is no problem at all.
