Projector

Abstract

The invention relates to a projector which comprises a projector shell, an optical engine, a light source structure and a lens unit, wherein the optical engine is contained in the projector shell; the projector shell is provided with a bottom surface; the optical engine comprises a shell, and the optical engine shell is provided with an emergence opening and an incidence opening in the same direction; the lens unit and the light source structure are respectively opposite to the emergence opening and the incidence opening and form a certain height difference relative to the bottom surface; the light source structure is provided with a shell and a plurality of light sources; the light source structure shell comprises a first side plate which is attached to the lens unit and a top plate which is perpendicular to the first side plate; the top plate is parallel to the optical axis direction of the lens unit in the extending direction of the optical engine; and the light sources are fixed on the top plate, and the light-emitting directions of the light sources face to the bottom surface.

Description

technical field [0001] The present invention relates to a projector. Background technique [0002] With the advancement of projector technology, projector products tend to be more and more small in size, light in weight, easy to carry and reduce in price. In order to achieve the above-mentioned reduction in size and price, the optical engines of many small projectors have abandoned traditional light bulbs, and instead use light-emitting diode modules (hereinafter referred to as LED modules) that are small in size, difficult to generate heat, and have a long service life. light source. [0003] In the known technology, the light source of the projector is generally arranged on the side of the optical engine, so that the lateral length of the projector is increased, and the structure of the projector is not square enough. And because the space other than the side is used to accommodate the light source, there are too many unnecessary gaps in the entire projector, so that a c...

Problems solved by technology

[0003] In the known technology, the light source of the projector is generally arranged on the side of the optical engine, so that the horizontal length of the projector is increased, and the structure of the projector is not square enough.

And because the space other than the side is used to accommodate the light source, there are too many unnecessary gaps in the entire projector, so that a compact structure cannot be formed

[0004] In addition, during the molding process of the optical engine, the groove for fixing the light source needs to be formed by adding a molding slider, which increases the cost of the mold
