Abstract
A projector apparatus and a lamp fixation structure for use with the projector apparatus are disclosed. The lamp fixation structure has a lower holder, which includes an integrally formed lower holder lens section and a lower holder lamp section. The lower holder lens section defines a lens fitting slot for fixing a lens, and a lower holder lamp section defines a lamp fitting slot for fixing a lamp. The lens fixing slot includes an upper holder connected to the lower holder. The lamp fixation structure also includes an integrally formed metal holder, which has an elastic top plate, elastic lateral plates, a front plate, an elastic bottom plate, and elastic jointing plates. The inventive lamp fixation structure of the projector apparatus consists of a fewer components and can be assembled in a simple manner, yet it is highly wrought.
