Problems solved by technology
Generally speaking, the structure that is only fixed on the upper end will form a hanging fixing method after the lamp cup bears all the light source components of the lamp. The load of the light source of the lamp is easy to cause deformation of the lamp cup , so that the correct relative position of the light source of the lamp and the optical assembly will change, which will also affect the optical characteristics of the optical engine and reduce the quality of the projector product

The invention provides a fixing structure for a lamp of a projector. The fixing structure comprises a lamp module, a jointing member and an x ray machine casing, wherein the jointing member is provided with a first side surface and a second side surface; the first side surface is connected with the lamp module; the second side surface is positioned on the back surface of the first side surface and is connected with the x ray machine casing; the lamp module is arranged relatively to the x ray machine casing through the jointing member; the jointing member is connected with at least two combined members of the lamp module. Through the adoption of the positioning combination of the jointing member and the lamp module, the structure is firm, the deformation is avoided, and the optical performance is maintained.
Description
technical field [0001] The invention relates to a lamp fixing structure for a projector, in particular to a lamp fixing structure for a projector that avoids affecting optical performance due to deformation. Background technique [0002] The optical engine (Optical Engine) is an important key component in the structure of projector products, which includes a lamp light source and an optical component. The light source of the lamp is a modular structure, which has components such as a bulb, a lampshade, a lamp holder, and a lamp cup, and is used to generate a projected light beam to irradiate toward the optical assembly. The optical components are also of modular construction, and components including a color wheel, an integrating column, a projection lens, a polarization splitting prism, and a light combining prism are set in an optical machine housing to guide the lamp The projected light beam of the light source is subjected to optical operations such as light separation,...
