Abstract
Disclosed is a mounting structure for a lamp comprising a lamp having a funnel, a frame attached to a front end of the funnel and a connecting bolt provided at a rear portion of the funnel a lamp holder, which is adapted to hold the lamp therein while maintaining a desired lateral gap at each side of the frame of the lamp, have a bottom plate, a front plate and a pair of side plates. The lamp mounting structure maintains an alignment of the optical axis of the lamp while effectively preventing the lamp from being damaged due to a thermal expansion thereof.
Claims19
A mounting structure for a lamp comprising:
- a lamp having a funnel, a frame attached to a front end of the funnel and a connecting bolt provided at a rear portion of the funnel;
- a lamp holder, which is adapted to hold the lamp therein while maintaining a desired lateral gap at each side of the frame of the lamp, have a bottom plate, a front plate and a pair of side plates;
- and
- a guide that elastically support the lamp in position comprises hinges formed at the opposite ends of the guide and mounted on the bottom plate of the lamp holder in a manner that allows the hinges to rotate, an engagement member arranged at an intermediate portion of the guide and placed at an upper end of the front plate of the lamp holder and a contact member formed at the opposite sides of the engagement member and comes in contact with the lamp.
A structure for mounting a lamp of a projector comprising:
- a lamp having a funnel, a frame attached to a front end of the funnel, and a connecting bolt provided at a rear portion of the funnel;
- a lamp holder that adapted to hold the lamp includes a pair of side plates arranged at opposite sides of the frame of the lamp while maintaining a desired lateral gap from an associated one of the opposite sides of the frame, a front plate being in contact with a front surface of the frame while applying a force to the lamp in a direction toward the lamp, and a bottom plate being in contact with a bottom surface of the frame and supporting the frame in a downward direction;
- and
- a tension guide that adapted to elastically support the lamp in position includes the hinges provided at opposite ends of the guide and hingably mounted to the bottom plate of the lamp holder, contact members having at least four contact points with the funnel where the tension guide come into contact with the funnel of the lamp and engagement member, which is an extension of the contact members, arranged at an intermediate portion of the guide and engaged with an upper end of the front plate of the lamp holder.
A structure for mounting a lamp in a projector, comprising:
- a lamp support adapted to support the frame of the lamp while maintaining a desired gap from the frame;
- and
- return means having at least four contact points to apply an elastic force to the lamp when the lamp moves out of the position, thereby returning the lamp to an original position thereof where an optical axis of the lamp is aligned in position.
