摘要： A lamp unit with a light control function for the light emitted from this lamp unit, for which a high pressure mercury lamp is used which is filled with at least 0.15 mg/mm 3 mercury and which has a hermetically enclosing arrangement, an essentially hermetically enclosing arrangement or an arrangement in which there is a flow path for actively flowing cooling air within. The lamp unit for a projector has a high pressure mercury lamp of the short arc type with a wall load of at least 1 W/mm 2 which is filled with at least 0.15 mg/mm 3 mercury, a concave reflector which surrounds this mercury lamp, a front cover which covers the front opening of this concave reflector, a cooling arrangement which can be controlled with respect to its cooling intensity for cooling of the concave reflector and/or the mercury lamp and a control device by which the power of the mercury lamp can be changed, the cooling and the control device being made such that, by controlling the two, a value in the range of 1 3 ) is the inside volume of the concave reflector, W (in W) is the rated power of the mercury lamp and G (in W/mm 2 ) is the wall load. Furthermore, a process for light controlling such a lamp unit is given.

摘要： There is provided a light source unit for a liquid crystal projector such as a so-called two purpose type liquid crystal projector which can advantageously be used in a device which does not discriminate between the top and bottom plates being oriented in an upward or downward position and in which the inner space of the light source unit is kept substantially hermetically sealed and can be efficiently cooled. Foreign bodies such as pieces from the breakage of the lamp do not drop out of the light source unit and thus do not damage the other components due to the specific construction of the light source unit which is comprised of a light source lamp, a concave reflector for projecting reflected light from the light source lamp in a substantial horizontal direction, a transparent front plate covering the front opening of the concave reflector, and aeration ports formed near the front circumferential edge of the concave reflector which are arranged only at the lateral side of the light source unit.
