To provide a simple and inexpensive means capable of achieving effective thawing of ice on a cover glass of an illumination device for an automobile, which does not lead to undesired local variations in temperature dependence of light distribution.SOLUTION: In the present invention, a cover glass 12 can be heated. To achieve heating of the cover glass 12 as uniformly as possible, the cover glass 12 in a beam path 19 includes a conductive layer 26 having at least one nanotube formed of a conductive material. A voltage U is applied to the layer 26 at least temporarily, and an electric current I flows through the layer 26. As a result, this layer 26 is heated uniformly, and the heat of the layer 26 heats the cover glass 12.SELECTED DRAWING: Figure 3

    【課題】自動車用照明装置のカバーガラスの効果的な解氷を実現すると同時に、このことが配光の温度依存性の不所望な局所的変動につながらない、簡単で安価な手段を提供する。【解決手段】本発明は、カバーガラス12は加熱可能である。可及的に均一なカバーガラス12の加熱を可能にするために、ビームパス19におけるカバーガラス12が、少なくとも1つの導電性材料からなるナノチューブを有する導電層26を備え、少なくとも一時的にこの層26に電圧Uが印加され、それによって、この層26を通って電流Iが通流し、その結果、この層26が一様に加熱され、この層26の熱がカバーガラス12を加熱する。【選択図】図3
