PURPOSE: A DLP(Digital Light Processing) optical engine is provided to automatically correct an optical axis by a floating structure of a lamp bracket when matching a lamp unit with an optical engine unit. CONSTITUTION: A lamp unit forms a white light and provides the formed white light. An optical engine unit(200) converts the light received from the lamp unit into a suitable image signal. An optical engine supporting board(300) supports the lamp unit and the optical engine unit(200). The lamp unit has a lamp, a lamp bracket, a bracket supporting plate, a lamp case(120) and a lamp housing(110). The lamp forms a white optical source. The lamp bracket fixes the lamp. The bracket supporting plate is fixed in a state in which it is possible for the lamp bracket to be floated. The lamp case(120) accepts the lamp and the lamp bracket by connecting to the bracket supporting plate so that the bracket supporting plate is formed as one side wall. The lamp case(120) is inserted into the lamp housing(110).
