摘要：
A lighting device (10) which is adapted to be converted between a flashlight mode and an area light mode includes a housing (14) to receive a power supply (28), a light source (46) associated with the housing (14) and a tubular lens (34) surrounding the light source (46), a reflector (52) mounted to said device (10) so as to slide relative to the tubular lens (34), the reflector (52) including an aperture (68) through which the light source (46) can pass, the aperture (68) having a shutter (70) associated therewith whereby the shutter (70) closes the aperture (68) when the reflector (52) is in a position which allows the device to be used in the area light mode.
