Claims (8)
- 光線を発する少なくとも1つの光源と、該光線を投射面上に導光する手段とを含む照明装置であって、
前記導光手段が、前記投射面に対して垂直な軸に沿って延設された円柱部分と、該円柱部分の端部に延設され、前記光源から発せられた前記光線の一部を前記投射面に向けて方向付ける少なくとも1つの凸状表面とを呈するレンズにより形成されていることを特徴とする照明装置。 - 前記円柱部分が、円形基底面、湾曲基底面、メニスカス基底面、フレネル基底面の中から選択された基底面を有することを特徴とする請求項1記載の照明装置。
- 前記レンズが、前記円柱部分の両方の端部に2つの凸状表面が延設された形状とされていることを特徴とする請求項1記載の照明装置。
- 前記凸状表面が、前記円柱部分の前記軸周りに回転対称な、半球面状の表面であることを特徴とする請求項1記載の照明装置。
- 前記凸状表面が放物面状であることを特徴とする請求項1記載の照明装置。
- 同一のレンズに対して複数の発光ダイオードを含んでいることを特徴とする請求項1記載の照明装置。
- 前記投射面が、屈折および拡散によって光を透過させるようにされた透明材料のシートであることを特徴とする請求項1記載の照明装置。
- 当該照明装置が、前記光源から見て、前記レンズよりも後方に配された光学素子をさらに含み、
該光学素子は、当該照明装置が前記投射面上に有意な像を投影するように、列ごとに描画された特徴を呈していることを特徴とする請求項1記載の照明装置。
