Problems solved by technology

[0011] However, if the width of the light source inlet is increased, the performance of the optical instrument 10 will be greatly reduced, so the situation of using more than two light sources to increase the amount of light is comparable to that of keeping the width of the light sources in half and using only one lamp. than, the amount of light is the same or lower

Embodiment Construction

[0025] For other purposes, properties and characteristics of the present invention, please refer to the accompanying diagrams and descriptions of the embodiments. Embodiments of an optical integrator using optical tracks according to the present invention will be described below with reference to the drawings.

[0026] FIG. 3 is a schematic diagram of an optical integrator using an optical rod or an optical tunnel in the present invention. As shown in Fig. 3, in the optical integrator where the light emitted from the light source is collected within a certain area, the optical integrator includes the following parts: at a position parallel to the optical axis of the first light source 300, for the emitted light The main integrator (MI) 100 that the light source plays a converging role; at least one or more is arranged on the side of the main integrator 100, and from more than one light source 300' different from the above-mentioned first light source 300, at a position paralle...

Abstract

The invention relates to an optical integrator, i.e. on the condition of using above two light sources, able to effectively increase the emitted light quantity without increasing inlet width of the optical orbit and playing a role in collecting the light emitted from the light sources, and it comprises: a main integrator to collect the incident light parallel with the axis of the light emitted from the first light source, where the sides of the main integrator are provided with at least one sub integrator to collect the light from the first light source and sub light source into the main integrator.

Description

technical field [0001] The present invention relates to optical instruments, and in particular to integrators used in projector systems. Background technique [0002] Recently, imagers such as lamps, liquid crystals, DMDs, and LCoS are used in projectors to form images. Uniform, generally use an integrator (Integrator), the integrator uses FEL (Fly Eye Lens: flying eye lens) and light rod or light tunnel (Light Rod (Tunnel)). [0003] At this time, the structure of the optical system can be simplified by using the fly-eye lens in the optical tunnel. The light rod is a hexagonal rectangular block, which acts as an integrator through internal total reflection. The light tunnel mentioned above utilizes the reflection of four mirrors to realize the function of the integrator. The basic principles of use of the two integrators are the same. [0004] FIG. 1 is a schematic diagram of an optical integrator using an optical rod or an optical tunnel in the prior art. It produces ...
