PURPOSE: A device for coupling a lamp of a projection system is provided to control a position of a lamp reflection mirror for realizing an optimum designing of required parts and easily evaluate the optical performance without using any jig by setting an assembling position with a protrusion part and controlling the assembling position by a position control screw. CONSTITUTION: In a device for coupling a lamp of a projection system, of which illumination optical part includes the lamp as a light source, a reflection mirror(3) surrounding the lamp, and a lamp holder part(2) for supporting the reflection mirror, the reflection mirror is supported by a reflection mirror holder(7) and the reflection mirror holder is supported in the lamp holder by a coil spring(6), wherein bosses(5) are formed on a front surface part of the lamp holder for maintaining a uniform distance between the lamp and the lamp holder and screws are inserted into thread parts of a bending part on a front surface of the lamp holder for controlling assembling angles in beta and gamma directions. |
