Problems solved by technology
[0004] However, in actual operation, due to component tolerances in the design of the multiple light-emitting elements and multiple reflectors of the solid-state light source array, or due to the light source characteristics of the light-emitting element itself (such as the light output angle), the light reflected by the reflectors The light beam cannot be directed to the condenser lens for focusing, and there is no appropriate adjustment mechanism for multiple reflector groups, so that the light source provided by the solid-state light source array cannot be effectively converged, resulting in energy consumption and reducing the use efficiency of the light source system In addition, insufficient light intensity entering the projection device will affect the imaging quality and brightness, and because the reflected light beam does not travel along a specific light path, it will also cause the problem of thermal temperature rise in the light source system

The invention discloses a light source system which is suitable for a projection device and at least comprises a first light source module comprising a plurality of first light sources, each first light source providing a first light beam; a first reflector group comprising at least one first reflector arranged on an optical axis of the first light source correspondingly; at least one first fixation device for fixing the first reflector; and at least one first adjusting mechanism coupled with the first fixation device, wherein the first fixation device can move and rotate along the axial direction of the first adjusting mechanism in an adjustable manner to translate and rotate the position and angle of the first reflector with respect to the first optical axis to allow the first light beam reflected by the first reflector to be guided to a specific light path. The light source system is allowed to reach the optimum efficiency in utilization, and meanwhile, can prevent the problems of energy loss and overheat of the light source system due to errors in assembly or of components or in an existing light source system.
Description
technical field [0001] The invention relates to a light source system, in particular to a light source system with a light source array reflection adjustment mechanism. Background technique [0002] In recent years, various projection devices, such as projectors (Projector), have been widely used in families, schools or various business occasions to enlarge and display an image signal provided by an image signal source on a screen. . With the development of projection devices towards thinner, high image quality and low energy consumption, in order to meet the aforementioned requirements, the light source system (Illumination System) of current projection devices uses solid-state light-emitting elements, such as light-emitting diodes or laser elements, to replace traditional High-density gas discharge lamp (HID Lamp) or high-pressure mercury lamp. [0003] Generally speaking, light source systems using solid-state light-emitting elements are mostly designed as group light s...
