    摘要: An optical scanning device (1) for scanning an information layer (4) of an optical record carrier (2), the device (1) comprising a radiation source (11) for generating a radiation beam (12, 15, 20) and an objective system (18) for converging the radiation beam on the information layer, the information layer being covered by a transparent layer (3) of thickness td and refractive index nd. The objective system comprises a lens having a protection device projecting away from the lens towards the optical record carrier such that the distance between the protection device and the optical record carrier is less than the free working distance. The lens satisfies the condition: where D is the entrance pupil diameter, FWD is the free working distance, and D, FWD, t and td are all expressed in millimeters and where FWD+td/nd

    摘要: The disclosed embodiments relate to a light guide (100) and a luminaire (700) including such a light guide (100). The light guide (100) guides light emitted in a first direction (500) from a light source (200) comprising at least one light emitting diode (210). The light guide (100) directs a major part of the light in a second direction (600), wherein the first direction (500) is not equal to the second direction (600). The light guide (100) comprises an upper part (110) having a shape of a cone, and a center axis (120) of the upper part (110) is in the first direction (500). The light guide (100) can be used with reflectors (800) that have originally been manufactured for use with high intensity discharge lamps or halogen lamps but because of the light guide (100), the reflectors (800) can be used together with light sources (200) in the form of at least one light emitting diode (210).
