| 摘要 |
A lens (12; 32; 42; 52) comprising a transparent main body (13; 43; 53), wherein a surface (14, 15; 14, 45; 54, 55) of the main body (13; 43; 53) is at least partly covered with an internally reflecting reflection layer (17), the lens (12; 32; 42; 52) has at least one first focal point (F1) and at least one second focal point (F2), at least the first focal point (F1) lies at least partly on a non-covered surface region of the main body (15; 45; 55), and at least one phosphor element (18) bears against the main body (13; 43; 53) at a contact region (19) having at least one first focal point (F1). |
